The Limping Child
4 year old child presents to the emergency department with a chief complaint of limping for two days
No report of trauma Afebrile No additional systemic symptoms PMH negative for joint problems or chronic disease Nontender to palpation and no pain with passive
ROM but limps when bears weight Differential? Workup?
3
Transient Synovitis - Definition
Also known as “irritable hip” or “toxic synovitis” The #1 cause of acute hip pain in children Benign self limited disease of uncertain etiology
most commonly affecting the hip joint Usually occurs in children age 3 to 10 years 4 cases in adults have been reported Almost always unilateral Causes pain and limitation of the movement of the
hip, with or without an effusion Pain is the worst when walking, usually presents
with a limp or refusal to bear weight
4
Transient Synovitis – Etiology, Treatment
Due to transient sterile inflammation of the synovium of the hip
No clear precipitants, ?post viral Sudden onset, gradual resolution Self limited, usually lasts 4-7 days Treated with OTC analgesics: ibuprofen and tylenol Study done showed ibuprofen decreased median
duration of symptoms from 4.5 days to 2 days No residual long term deficits Most important thing to do is distinguish it from
septic arthritis
5
Septic Arthritis - Definition
Results from bacterial invasion of the joint space Can occur at any age but 50% of cases reported
occur in children under the age of 3 years Acute onset Usually monoarticular Usually the large peripheral joints Organisms can invade the joint by three possible
mechanisms:• Usually through hematogenous seeding• Adjacent osteomyelitis• Direct inoculation from a penetrating wound
6
Septic Arthritis - Bugs
• Staphylococcus aureus• Streptococcus
GBS S pneumoniae S pyogenes
• Neisseria gonorrhoeae• Haemophilus influenzae
7
Septic Arthritis - Presentation
Most commonly involves the hip joint “septic coxitis”
Symptoms include:• Fever• Joint pain• Limp and an inability to
bear weight• Pain with active or
passive range of motion• Joint swelling, effusion,
warmth, tenderness The patient holds their leg in
a flexed, abducted, externally rotated position
8
Septic Arthritis - Presentation
May be extremely difficult to diagnose in infants and nonverbal children
Fever, irritability, and decreased po intake may be your only clues
May fuss more when handled due to movement of the affected extremity
May have decreased movement of an extremity Predisposing factors include recent URI or otitis,
skin or soft tissue infections, traumatic puncture wounds, femoral venipunctures, underlying chronic disease, or immunosuppression
9
Septic Arthritis - Differential
Differential can include:• Transient synovitis• Viral arthritis• Traumatic arthritis• Periarticular cellulitis• Osteomyelitis• JRA• Acute rheumatic fever (JONES criteria)• Lyme disease• Post-infectious reactive arthritis• Oncologic process (eg. leukemia, osteosarcoma)
10
Septic Arthritis - Diagnosis
Laboratory: CBC with diff shows elevated white count with a left
shift Blood cultures are positive 40-50% of the time CRP elevated ESR elevated Joint aspiration shows elevated WBC’s 10,000-
250,000 (normal is less than 200), >75% segs, and decreased glucose
Imaging:• Plain films may show a displacement or blurring of
periarticular fat pads as well as an increased hip joint space
• MRI
11
Septic Arthritis - Diagnosis
Study done by Jung, et al. (2003*) found five predictors that correlated with a high probability of septic arthritis to help distinguish from transient synovitis whose presentation can be similar• Temperature >37 degrees Celsius (37.7 vs. 36.6)• WBC >11,000/mL (18.2 vs. 8.2)• CRP >1mg/dL (10.1 vs. 0.66)• ESR >20mm/h (79.2 vs. 20.3)• Joint space difference >2mm between the
affected and unaffected sides (difference of 4.0mm vs. 1.2mm)
• No significant difference found in platelet count
12
Septic Arthritis - Treatment
Treatment:• Prompt orthopedic consultation• Surgical debridement of the hip through
arthrotomy• Hospitalization until fever defervescence and
signs of clinical improvement post operatively• Intravenous antibiotics for 4 weeks• Usually requires central line placement for home
administration of antibiotics
13
Septic Arthritis - Treatment
Antibiotic Therapy• <2 months of age: oxacillin or nafcillin plus
gentamicin for Gram negatives• 2 months to 3 years: ampicillin-sulbactam or
ceftriaxone• >3years: oxacillin, nafcillin, or ceftriaxone• Adjust based on gram stain and culture results• Consider Clinda or Vanc if suspect MRSA
14
Septic Arthritis - Outcomes
Complications• Osteomyelitis, osteonecrosis• Avascular necrosis due to the pressure on blood
vessels and cartilage in the femoral head area• Epiphyseal separation• Pathologic dislocation• Growth arrest and subsequent leg length
discrepancies up to several inches• Sepsis
15
Septic Arthritis - Outcomes
Prognosis• Joint destruction can occur within days leading to
longterm disability, residual deformity, arthritis, and decreased range of motion
• Prior to the discovery of antibiotics, pediatric mortality rates averaged 50%
• If diagnosed early before changes seen on plain films, have an improved prognosis
• Note that joint destruction as a result of gonococcal infection is uncommon
16
SCFE: Slipped Capital Femoral Epiphysis
An acquired growth plate injury The separation of the proximal femoral epiphyses from
the metaphysis at the level of the growth plate Most commonly occurs in adolescents and
preadolescents who are vulnerable to slippage due to widened and weakened growth plates during periods of rapid growth
Occurs in 2-10 per 100,000 adolescents in the US Peak age is 10-13 in females and 12-16 in males Rarely occurs after menarche More common in males, male to female ratio is 2.5 :
1.6 More common in Pacific Islanders and African
Americans
17
SCFE - Etiology
The epiphysis is located at the top of the femur and is connected to the metaphysis via the physis or growth plate
The head of the femur stays within the acetabulum while the femur slips
Occurs when the shearing stress exerted onto the femoral head is greater than the resistance provided by the physis
Occurs in the hypertrophic zone, the weakest zone of the physis
18
SCFE - Risk Factors
• Obesity resulting in mechanical overload of an immature growth plate, 81% of cases are in children over the 95th percentile for BMI
• Local trauma• Hypothyroidism• Panhypopituitarism• Growth hormone administration• Renal osteodystrophy• Previous radiation therapy
19
SCFE - Presentation
• Limp• Hip, groin, thigh, or knee pain• Hip pain often referred to the knee due to the pathways of
the obturator and femoral nerves• 15% of patients report pain only in the distal thigh and
medial knee• If stable, can still bear weight• As the slip progresses, eventually get external rotation of
the toes when walking• Decreased range of motion of the hip• If chronic or unrecognized, may develop atrophy of the
thigh and gluteal muscles• A stable chronic slip may suddenly worsen and become
unstable with what seems like minor trauma
20
SCFE - Diagnosis
Radiography: bilateral A/P and frog leg x-rays of the hips
“Ice cream falling off the cone” the femoral head is the ice cream that falls off the femur which is the cone
21
SCFE – Grades of severity
22
SCFE - Treatment
• Screw fixation under fluoro to prevent further slippage
• Strict non weight bearing leading up to surgery and then partial for 6-8 weeks after surgery
• Never attempt to reduce the slip during surgery or will increase the risk of avascular necrosis
• For severe slips, a corrective osteotomy may be required
23
SCFE - Treatment
• Technically only need fixation until the growth plate fuses but would be too invasive to remove the screw, so they are usually left in unless complications develop
• Some will do prophylactic pinning of the contra- lateral hip if at high risk for a bilateral slip
• Casting or bracing not required postop
• Sports restrictions for 3-6 months
24
SCFE - Complications
• Avascular necrosis: altered blood supply to the proximal femoral head and physis leading to bone death, most commonly occurs in severe or unstable slips, can lead to rapid hip deterioration and severe progressive arthritis
• Chondrolysis: necrosis of the articular cartilage, can progress to severe pain, decreased range of motion, and contracture of the hip
25
SCFE - Prognosis
• Occurs bilaterally in 25-40% of cases• Most contralateral slips occur within 6-12 months
of the index case• Most stable or chronic SCFE’s are treated
effectively with minimal complications, makes up >90% of all slips
• The more severe the slippage, the more altered are the mechanics of hip movement, and the sooner the hip wears down, leading to premature arthritis
• The most severe cases may eventually require total hip replacements
26
Legg-Calve Perthes Disease
Aseptic necrosis of the femoral head and neck Results from a disruption of the blood supply Onset usually between the ages of 4-8 years Male to female ratio of 5:1 Bilateral in 10% of cases Present with a limp Pain may refer to the knee, medial thigh, or groin
along the distribution of the obturator nerve Exam reveals limited hip abduction and medial
rotation More advanced cases may show leg length
shortening or thigh muscle atrophy
27
Legg-Calve-Perthes Disease
The exact cause is unknown but can be related to anything that may damage the blood supply to the hip:
28
Legg-Calve-Perthes Disease
Radiographs show:• Smaller denser femoral head• Relative osteopenia of the adjacent proximal femur and pelvis• Widened joint space• Subchondral lucent area• Irregular physeal plate, fragmented in later stages• Blurred and lucent metaphysis
Confirm with MRI or bone scan
29
Legg-Calve-Perthes Disease
A temporary condition Occurs in 4 phases:
• 1. From several months up to one year, blood supply is absent, portions of the bone die, the femoral head collapses and looses it’s shape
• 2. From one to three years, the dead cells are replaced with new bone cells
• 3. Also from one to three years, the femoral head begins to remodel and obtain its shape again
• 4. Completion of the healing process
30
Legg-Calve-Perthes Disease
Treatment:• Rest, often with the aid of crutches, wheelchair• Activity restrictions• NSAIDS• Traction, casting, or bracing to hold the femoral head in the
hip socket to preserve the round shape of the femoral head during remodeling
• Surgery to secure the femoral head in the hip socket• Physical therapy to keep the hip muscles strong and
maintain range of motion Complications:
• Limited hip motion• Leg length differences• Arthritis long term
31
Osgood-Schlatter Disease
Tibial tubercle apophysitis Due to traction of the patellar ligament on the tibial
tuberosity An overuse syndrome Occurs most frequently in boys age 11-15 years
who are active in sports Pain to palpation of the tibial tubercle, pain with
quadriceps contraction May have overlying soft tissue swelling Radiographs are either normal or may show an
irregular tibial tubercle with or without fragmentation Often mistaken for avulsion fractures
32
Osgood-Schlatter Disease
Self limited Cured by fusion of the
tubercle Treatment is limitation of
physical activity to the point of pain tolerance and RICE• Rest• Ice• Compression with ace
wrap or neoprene sleeve• Elevate
NSAIDS may help with acute pain exacerbations
33
Osteomyelitis - Definition
An infection of the bone 90% of cases involve a single bone Pathogens can spread to the bone from the blood
stream from distant infections, from direct penetration from trauma, or from spread from overlying soft tissue infections
Long bones of the lower extremity are the most commonly affected from hematogenous seeding
Usually beneath the epiphyseal plates in the rapid growth areas
Up to 25% may occur in short or nontubular bones
34
Osteomyelitis - Bugs
• Staphylococcus aureus is the number one cause in any age group! 70-90% of cases!
• Haemophilus influenzae• GBS and enteric rods in neonates• Salmonella in sickle cell patients• Pseudomonas aeruginosa in foot
punctures
35
Osteomyelitis - Presentation
Symptoms:• Limp• Difficulty bearing weight• Bone pain, gradual onset, constant• Infants are usually fussy, febrile, and may not be
moving all extremities equally• Fever over 38.5 C in up to 80% of patients
Physical Exam:• Point tenderness on exam• Local erythema and edema once purulent
material has ruptured through the bone cortex
36
Osteomyelitis
37
Osteomyelitis - Diagnosis
• Laboratory White blood cell count is normal in up to two thirds of
cases! An elevated ESR is more sensitive, elevated in up to
90% of cases, peaks at day 3-5 of treatment, normalizes by 3 weeks
CRP is best for monitoring response to treatment, elevated in up to 98% of cases, peaks at day 2 of treatment, normalizes in as little as one week in uncomplicated cases
Blood culture yields an organism in 30-50% of cases• Bone aspiration for gram stain and culture yields an
organism in 50-70% of cases
38
Osteomyelitis - Diagnosis
Radiographs may be normal early in the course but as bony destruction occurs, may see periosteal reactions (in 3-10 days) or lytic lesions (in 10-12 days)
Technetium-99 bone scan will show areas of increased blood flow due to inflammation, sensitivity >90% (note: your bone scan won’t be affected by needle aspiration)
If have a poor treatment response, consider MRI which can aid in finding drainable subperiosteal abscesses
If have a pelvic osteomyelitis, consider MRI early in the course of evaluation due to an increased occurrence of abscesses in these cases, or can use MRI to replace bone scan in the diagnosis of these cases
39
Osteomyelitis
40
Osteomyelitis
41
Osteomyelitis - Treatment
• All cases must be admitted for IV antibiotics• Immediate orthopedic consultation is required for surgical
debridement and draining of any subperiosteal abscesses• Total antibiotic course of 3-4 weeks, up to 6 weeks in
complicated or extensive cases• Sickle cell patients who may have areas of poorly perfused
bone as well as immunocompromised patients require longer treatment duration
• Use the max dosage range listed for the antibiotic chosen• IV route until clinical symptoms improved and afebrile for at
least 3-5 days• Can then complete treatment course with oral high dose
antibiotics
42
Osteomyelitis - Treatment
Antibiotic Therapy:• Anti-staphylococcal penicillins:
Oxacillin (and gentamicin) in neonates Nafcillin or oxacillin monotherapy in older
children• First generation cephalosporins
Ancef (cefazolin)• Clindamycin if suspect MRSA• Vancomycin if clinda resistant or D test positive
for inducible clinda resistance• Linezolid as last resort for highly resistant
organisms
43
Osteomyelitis - Outcomes
Complications:• Bony and cartilaginous destruction• Growth arrest• Permanent deformity• Sepsis• Chronic or recurring osteomyelitis
Prognosis:• Complications occur in only ~5% of cases,
usually when there was a delay in diagnosis or treatment
• Recurrences can occur up to 30 years later, usually the same organism, often reactivated by local trauma
44
Compartment Syndrome
Due to an increase in intracompartmental pressure From anything that decreases compartment size:
• Tight closure of fascial defects• Tight dressings or casts
Or from anything that increases comparment components:• Bleeding from fractures or trauma• Increased capillary permeability from burns• Venous obstruction• Muscle hypertrophy
Can result in ischemic muscle necrosis and subsequent contracture and dysfunction
45
Compartment Syndrome
The lower leg is most susceptible due to its small fascial compartments
Irreversible muscle injury may occur in as little as 6 hours from onset of ischemia
Diagnosis “The Five P’s”• Pain out of proportion to the injury, exacerbated
by passive stretching of the muscle• Paresthesia• Pallor• Paralysis• Pulselessness
46
Compartment Syndrome
Treatment• Loosen all restrictive dressings or splints• Direct measurement of compartment pressures if
pain not immediately relieved• Incisional release or fasciotomy required if any
compartment pressures are over 30mmHg
47
Fractures: Definitions
Alignment: refers to angulation or rotation of the fracture fragments in reference to each other
Apposition: refers to the amount of end to end contact between the fractured bone fragments
Avulsion: “chip fracture”, small fracture near a joint that usually has a ligament or tendon attached
Closed: “simple fracture”, no overlying open wound Open: “compound fracture”, open wound present Comminuted: multiple fragments Dislocation: “luxation”, disruption of the continuity of a joint Displaced: the two bone ends are separated Epiphyseal: involves the growth plate or epiphysis Greenstick: incomplete fracture Impacted: broken ends are driven into each other Intra-articular: involves the joint surface of a bone
48
Fractures: Definitions
Delayed union: slower than normal healing Malunion: healing in an unsatisfactory position Nonunion: failure of bone healing Occult: can’t see the fracture on the plain films but other
positive signs suggest a fracture such as a posterior fat pad on a lateral elbow film
Pathologic: due to an underlying bone weakness, usually cysts, neoplasms, or metabolic bone disease
Stress: occurs when weak bone is stressed normally or when normal bone is stressed excessively, usually in weight bearing bones
Subluxation: partial disruption of a joint, an incomplete dislocation, most common in pediatrics is nursemaid elbow
Torus: “buckle fracture”, caused by compression of the cortex, most commonly occurs in the distal radius
49
Pediatric Fractures
Fractures in children differ from those in adults Nonunion is rare due to the active periosteum and
abundant blood supply surrounding the growing bone
Continued bone growth after the fracture is healed allows for correction of minor deformities
The closer the fracture is to the end of the bone and the younger the patient, the greater the amount of angulation that is acceptable
The distal radius may correct up to 10-15 degrees per year
Side to side apposition is acceptable in long bone fractures in boys under 12yrs and girls under 10yrs
50
Pediatric Fractures
Slight shortening (overlapping of 2 bone ends) is acceptable and may even be desirable in leg fractures due to the acceleration of growth seen after a displaced fracture, the tibia and femur may overgrow up to 1cm
Exceptions:• Rotational malalignment will not correct itself• Angulated midshaft fractures will not realign
Sprains are rare in children under age 12 yrs, if tenderness is present over a growth plate coupled with overlying soft tissue swelling, assume a fracture even if x-rays are negative
51
Epiphyseal Fractures
The epiphyseal plate consists of zones or layers:• Germinal cell layer, closest to the joint• Zone of proliferation• Zone of hypertrophic cartilage• Zone of provisional calcification
Most epiphyseal fractures occur through the weakest zone, the zone of hypertrophic cartilage
52
Epiphyseal Fractures
Salter I and II fractures are transverse and do not extend vertically across the germinal cell layer, prognosis for normal healing is good
Salter III, IV, and V fractures extend vertically across the growth plate and have the highest risk for growth disruption and angular deformity, accurate reduction is mandatory and often requires surgery
Salter V fractures are crush injuries and have the worst prognosis
53
Pediatric Fractures
Call orthopedics for all of the following fractures:• Open fractures, often require meticulous cleaning
and debridement to prevent infection• Femur fractures, require prolonged traction,
special casting, or surgery• Displaced supracondylar humerus fractures• Salter III, IV, or V fractures (except fingers, toes)• Any closed angulated or displaced fractures for
which reduction attempts are unsuccessful• Any injury involving neurovascular compromise
or signs of compartment syndrome
54
Pediatric Fractures
Immediate care when patient presents to the ER:• Elevate and ice• Stabilize obvious fractures on an armboard, in a
sling, or on a stack of towels• NPO except for pain meds• Pain control depending on severity
IV Morphine PO Lortab
• Document last po intake• Consent signed for sedation if has obvious
deformity• Assess neurovascular status distal to the injury
55
Buckle Fractures
Torus or buckle fracture of the distal radius
The most common fracture in the pediatric population
Occurs from a fall onto an outstretched hand
May present a few days after the injury with mild wrist pain
Stable fracture, treated mainly for comfort
Treat with a lower arm sugartong splint in the ER
Later get a short arm cast or a removable volar wrist splint for 3-4 weeks
56
Clavicle Fractures
Occurs from a fall onto the shoulder or falling onto an outstretched hand Surgical correction only if open, skin tenting present, comminuted, or
has neurovascular injury Better to accept angulation/deformity than to attempt open reduction in
most cases The scar from an open reduction is usually more displeasing to the
patient and family than the bony prominence of a malunion Simple sling and swathe for 2-3 weeks or until painfree
57
Proximal Humerus Fractures
Common between the ages of 9-15yrs Occurs from a fall onto the arm or a direct hit The proximal humeral growth plate has an amazing
ability to remodel Reduction is only needed in patients near skeletal
maturity whose fracture has more than 50-70 degrees of angulation, in open fractures, or if has neurovascular injury
Most common complication is axillary nerve injury, test deltoid function and sensation lateral deltoid
Immobilize in a simple sling for 3-4 weeks Gentle pendulum exercises and shoulder range of
motion exercises can be started in the second week
58
Proximal Humerus Fractures
59
Supracondylar Fractures
Make up 60-80% of all pediatric elbow fractures Peak incidence ages 5-7 years Results from a fall with the elbow hyperextended, the
hyperextension forces the olecranon into the olecranon fossa transmitting the force up into the distal humeral metaphysis
The distal fragment is usually displaced posteriorly The anterior humeral line which should bisect the capitellum, is
malaligned anterior to the capitellum Has the highest complication rate of any pediatric fracture
including neurovascular injury, compartment syndrome, and malunion• Vascular injury occurs in ~2.5%, most commonly the
brachial artery• Neuronal injury occurs in ~17% of Type III fractures, can
affect the radial, median, or ulnar nerve
60
Supracondylar Fractures
Type I is nondisplaced Type II is displaced partially
with the posterior periosteal hinge intact
Type III is displaced completely with no contact between fracture fragments
61
Supracondylar Fractures
Type I can be treated with a posterior long arm splint with the elbow in 90-110 degrees of flexion, will later get a long arm cast for 3-4 weeks
Type II and III are usually treated with closed reduction and percutaneous pinning
62
Forearm Fractures
The distal radius physis is the most commonly injured physis in the body
Salter II fractures are the most common type of radial physis injury
Most displaced fractures involve apex volar angulation with the distal fracture fragment being displaced dorsally
63
Forearm Fractures
Most distal forearm fractures can be treated with closed reduction, but midshaft fractures are more unstable and often require pinning or plate fixation
Remodeling of the distal radius may correct up to 10-15 degrees of angulation per year
Therefore, angulation up to 30 degrees may be accepted in children under the age of 10 years, and up to 15 degrees in children older than 10 years as long as they have open physes
Remember, rotational deformities will not remodel
64
Forearm Fractures
Place a sugartong splint in the ER and then a cast for 4-6 weeks
Most common complication is growth arrest, occurs more commonly with difficult or open reductions
65
Boxer’s Fracture
Distal 4th or 5th metacarpal fractures
Results from hyperflexion of the metacarpal neck due to punching or hitting a hard object or wall
Treated with an ulnar gutter splint, then a cast for 3-4 weeks
Never reduced in the ER, all go to ortho clinic for follow up and have outpatient surgical repair if residual dysfunction is present
66
Femur Fractures
62% occur in the shaft of the femur or diaphysis
One of the most common fractures in children
The most common fracture requiring hospitalization
Between the ages 1-6 yrs, usually due to falls
Between the ages 6-9 yrs, usually due to auto vs. ped
Over the age of 10 yrs, usually due to MVC’s, sports accidents
Under the age of 12 months or in any child who is not yet walking, 80% are due to non accidental trauma
67
Femur Fractures
Treatment is often age dependent• Newborns to age 6 months: Pavlik harness• 6 months to 5-8 years: spica cast• 6-12 years:
Traction followed by a spica cast External fixation Flexible intramedullary nailing, no casting, just
a knee immobilizer needed post op, rods are removed 9-12 months later
• Skeletally mature with closed physes: Rigid intramedullary locking nails Compression plate fixation
68
Femur Fractures
Pavlik harness Spica cast
69
Femur Fractures
Remodeling of an infant treated with Pavlik harness
Flexible intramedullary nailing in an older child
70
Femur Fractures
External fixation Rigid intramedullary interlocking nails
71
Tibia Fractures
50% occur in the distal third of the tibia
39% occur in the midshaft region 30% have associated fibular fractures Due to falls, sports, MVC’s, and auto
vs pedestrian accidents Proximal third tibia fractures are rare
but the most complicated, tend to heal with a valgus deformity, treated with a varus molded long leg cast with knee flexed 10 degrees for 4-6 weeks, some valgus deformities resolve spontaneously so they aren’t surgically corrected unless persist into adolescence
72
Tibia Fractures
Middle and distal third tibia fractures require long leg splints in the ER followed by casting
Casting duration dependent on age• Young children wear a long leg cast for 3-4 weeks• Adolescents wear a long leg cast for 4 weeks, then switch
to a short leg cast for 4 weeks, then an aircast walking boot for 4 weeks
73
Toddler’s Fracture
Nondisplaced spiral fracture of the distal third of the tibia
The most commonly identified fracture in preschool-aged children presenting with a limp
Occurs from a fall that causes a twisting torque on the lower leg
Typically seen in patients aged 1-3 years as they are learning to walk, but can occur in children as old as 6 years
Long-leg or below-the-knee walking cast for 3-4 weeks
74
Ankle Fractures
Ankle inversion/eversion injuries can cause avulsion fractures of the lateral/medial malleolus tips respectively, or distal fibular physis fractures
Avulsion fractures of the distal medial or lateral malleolus may persist radiographically despite casting
Sometimes confused with a normal ossification center, if tender with overlying soft tissue swelling, treat as a fracture
Salter Harris I fractures of the distal fibula account for 15% of pediatric ankle fractures, often cannot be seen radiographically, it must be presumed in a growing child with tenderness over the physis
75
Ankle Fractures
Normal Pediatric Ankle Medial malleolus avulsion fracture
76
Nursemaid Elbow
Subluxation of the radial head due to a pulling or sudden traction injury followed by entrapment of the annular ligament between the radial head and the capitellum
Age 1-5 years Left side more common Slightly higher incidence in girls Usually caused by someone
lifting up a toddler by the lower arm or when a child suddenly pulls away or drops down while holding hands with a parent, also occurs from swinging a child as in playing “airplane”
77
Nursemaid Elbow
Presents with the arm hanging limp down by the side, nontender to palpation, but the child refuses to use the arm
Can reproduce pain with elbow flexion or supination
Reduced by applying pressure to the lateral aspect of the radial head while applying traction to the lower arm followed by supination and flexion at the elbow
This method works in 80-90% of cases
78
Nursemaid Elbow
An alternative method is hyperpronation at the wrist If unable to reduce, splint with elbow flexed at 90
degrees and send for orthopedic clinic follow up Often hear or feel a click Child usually cries briefly 10 minutes later the child is using it fully and
reaches for a toy or popsicle No splinting or sling necessary Motrin or Tylenol for soreness Tends to recur in 26% of cases
