    CHAPTER I

    INTRODUCTION

    Supracondylar fractures of the humerus are a common pediatric elbow injury that are

    historically associated with morbidity due to malunion, neurovascular complications, and

    compartment syndrome. True anteroposterior and lateral radiographs are essential not only

    for an accurate diagnosis, but also for creating a treatment plan for these injuries. A staging

    system (based on the lateral radiograph) for classifying the severity of the fracture helps

    guide definitive management. Nondisplaced fractures are treated initially with a posterior

    splint, followed by a long-arm casting. Closed reduction and percutaneous pinning is the

    preferred treatment for displaced or unstable fractures. If there is any question about fracture

    stability, patients should be seen within 5 days postoperatively for repeat radiographs to

    ensure that the reduction and pin fixation has been maintained. Understanding the anatomy,

    radiographic findings, management options, and complications associated with this fracture

    allow physicians to limit the morbidity associated with this relatively common pediatric

    injury.

    Supracondylar fractures are a common elbow injury in children accounting for 16% of all

    pediatric fractures [1] and two-thirds of all hospitalizations for pediatric elbow injuries [2].

    These are often significant fractures that may be associated with morbidity due to malunion,

    neurovascular complications, and compartment syndrome. Historically, a majority of these

    fractures were treated with closed reduction and long arm casting with the elbow in a position

    of greater than 100 of flexion. This flexed posture helped maintain the fracture reduction,

    but lead to problems with vascular compromise and subsequent Volkmans contracture. After

    a closed reduction, percutaneous pinning maintains fracture reduction without the need for

    immobilizing the elbow in significant flexion.

    CHAPTER II

    CONTENTS

    Definition

    Supracondylar fracture is a fracture of the distal end of the humerus located above the

    condylar region.3

    Epidemiology

    Supracondylar fractures are a common elbow injury in children accounting for 16% of

    all pediatric fractures and two-thirds of all hospitalizations for pediatric elbow injuries. 2,3

    Ambulant children of any age are vulnerable to supracondylar humeral fractures but the

    peak incidence occurs between the ages of 5 and 7 years, with the left arm most commonly

    affected. Boys sustain the majority of fractures but the gender gap is narrowing, reflecting a

    change in childhood activity.4

    Age is a key factor in the incidence of supracondylar fractures. This is a fracture that

    occurs more frequently in skeletally immature children than adults. The peak age for

    supracondylar fractures is between 6 and 7 years of age.6At this age, the supracondylar area

    is undergoing remodeling and is typically thinner with a more slender cortex, predisposing

    this area to fracture.

    Etiology

    The fracture is usually caused by a fall from height. Children under 3 years of age usually

    sustain the injury by falling from furniture, while older children sustain their fractures when

    falling from playground apparatus. It is very rare for this injury to be caused by physical

    abuse.

    Coincidental injury to any of the three major peripheral nerves around the elbow can

    occur and has a reported incidence of up to 15%. It may be detected immediately following

    the injury or may not be noted until after the subsequent treatment.4 The anterior interosseous

    nerve appears to be the most susceptible to damage from the original injury and radial nerve

    dysfunction is slightly less common.5 The ulnar nerve is the most vulnerable to iatrogenic

    injury from medial wire fixation.

    Associated ipsilateral fractures need to be excluded but are rare (5%).6 The vast majority

    of supracondylar fractures are closed (99%), with major vascular injury occurring in 3% or

    fewer children.5

    Classification

    There is 2 types of supracondylar fracture:

    - Extension type (95%)- Flexion type (5%)Gartland classification of extension fracture:

    Type I Undisplaced

    Type II displaced with posterior cortical hinge intact

    Type III displaced with no cortical contact

    Type I fractures can also include minimally displaced fractures with some separation of

    the anterior cortex in the sagittal plane, but the anterior humeral line still passes through the

    capitellum. Any rotational deformity qualifies the fracture as a type III. Intra-articular exten-

    sion of the fracture line can also be seen in some type III fractures.

    Leitch et al9proposed adding a type IV to describe the rarer but highly challenging severely

    displaced fracture with no intact periosteal hinge. The resulting multidirectional instability

    only becomes apparent under anaesthesia. From a practical point of view the introduction of

    this additional category does not influence the management, which is the same as for a type

    III injury.

    Pathogenesis of injury

    The ability to hyperextend the elbow joint is common in children owing to the normal,

    physiological ligament laxity of childhood.

    Supracondylar humeral fractures most frequently result from forced hyperextension of

    the elbow (95%). A fall on the outstretched arm results in hyperextension of the elbow, with

    the olecranon acting as a fulcrum in its fossa. Tension in the anterior tissues then exaggerates

    the effect with further force resulting in fracture of the medial and lateral columns of the

    relatively thin supracondylar region of the humerus. Continued extension force results in the

    proximal humeral segment being forced distally and anteriorly, which is when buttonholing

    of the bicipital aponeurosis and damage to the anterior neurovascular structures can occur.

    This mechanism results in disruption of the anterior periosteum but the posterior periosteum

    usually remains intact. This aids treatment by facilitating reduction and adding stability to the

    correctly reduced fracture. Integrity of the medial or lateral periosteum will be suggested by

    the lateral or, more commonly, medially displaced fracture. The direction of displacement in

    the coronal plane is indicative of the soft tissue structures at risk. With a medially displaced

    fracture the radial nerve is at risk, while lateral displacement is more likely to entrap the

    median nerve and brachial artery.

    The fracture line is usually transverse in the sagittal and coronal planes but a more

    oblique fracture line in either plane should alert the surgeon to the potential for greaterdifficulty in obtaining and maintaining a sound reduction.7

    The far less common (5%) flexion type supracondylar fracture results from a fall onto the

    point of the olecranon with the elbow flexed. Completely displaced flexion fractures can be

    very challenging to reduce and are associated with a risk of ulnar nerve damage.

    It is of interest to note that children who sustain a supracondylar fracture do not have a

    greater range of elbow hyperextension than those who sustain a fracture of the distal radius. 8

    Clinical Manifestation

    The child will present with pain, swelling, and limited elbow range of motion

    (ROM). A displaced fracture in extension typically has an S-shaped deformity. Swelling can

    be very rapid. Younger children can present with the appearance of a dislocated elbow.

    Always examine for associated injuries. A thorough neurological examination including

    screening of the median, radial and ulnar nerves should be undertaken and documented. If the

    median nerve is injured, patient failed to do opposition, and if the anterior interosseus nerve

    (branch of the median nerve) is injured, the digiti I and II failed to do flexion (pointing sign).

    If the radial nerve is injured, patient failed to do extension of the thumb and extension of the

    metacarpophalangeal joint. If the ulnar nerve is injured patient failed to do abduction and

    adduction of the finger. The radial pulse should be felt and documented. The skin should be

    assessed for swelling and bruising.

    Peripheral circulation problem may occur, it will shows palor of the skin, pulsesness,

    capillary refill time more than 2 second, poikilothermia.

    If the fracture is completely displaced at the distal humerus, the arm assumes an S-shaped

    deformity (Fig.2a). A pucker, dimpling, or ecchymosis of the skin just anterior to the distal

    humerus may indicate that the proximal, anteriorly directed fragment has penetrated the

    brachialis muscle and possibly the subcutaneous layer as well (Fig.2b). These physical exam

    findings often indicate that the fracture may be difficult to reduce by simple manipulation

    alone.

    Clinical signs that indicate urgent orthopedic review include :

    - Absence of radial pulse- Ischemia of hand : pale, cool- Severe swelling of forearm and or elbow- Skin puckering or anterior bruising- Open injury- Neurological injury

    Laboratory finding

    Low hemoglobin may occur in severe bleeding. Leucocytosis appear as an inflammatory

    responce because of the cell injuries or because of an infection.

    Diagnostic Imaging10

    The radiographic study of the injured limb should include an anteroposterior (AP) and a

    lateral view of the elbow and any other sites of deformity, pain, or tenderness. On the AP

    view, Baumanns angle is commonly used to evaluate fractures as it maintains an estimation

    of the carrying angle (the varus or valgus attitude of the distal humerus and elbow). This

    angle is created by the intersection of a line drawn down the axis of the humeral shaft and a

    line drawn along the growth plate of lateral condyle of the elbow (Fig.3a). Varus deviation in

    relation to the proximal humerus produces an increase in Baumanns angle. Radiographs of

    the contralateral elbow should be used for comparison, if needed, as Baumanns angle varies

    among all individuals.

    Figure 3

    (a) Baumanns angle is obtained on the

    anteroposterior radiograph by measuring the angle

    between a line perpendicular to the longitudinal axis

    of the humerus and a line parallel to the growth plate

    of the capitellum.

    (b) The anterior humeral line is a vertical line drawn

    directly on the anterior aspect of the distal humeral

    shaft that should pass through the mid-portion of the

    capitellum

    On the lateral view, the relationship between the anterior humeral line (a line drawn along

    the anterior aspect of the humerus) and the ossification center of the capitellum (Fig.3b)

    should be examined. In a normal elbow this line should pass through the capitellum.

    Additionally, on lateral view one may visualize a posterior fat pad sign which indicates an

    intraarticular effusion. An oblique view may be needed to visualize clinically suspected

    fractures that were not seen on AP or lateral views, especially isolated condyle fractures with

    intraarticular extension.

    Gartlands staging system, based on the lateral radiograph, is widely used for

    supracondylar fractures as it can help guide treatment. Gartlands Type I fractures are

    nondisplaced. Type II fractures are displaced with angulation, but maintain an intact posterior

    cortex (Figs.4ac). Type III fractures are completely displaced and lack cortical contact

    (Fig.5aand b).

    Treatment10

    After clinical assessment and

    diagnosis, the elbow should be splinted

    in a position of comfort (approximately 2030 of flexion) to provisionally stabilize the

    11

    limb. Splinting in full elbow extension is contraindicated because it stretches the

    neurovascular bundle over the fracture site in displaced or unstable fractures. The application

    of a comfortable, well padded, and appropriately applied splint is a critical part of the initial

    management of these injuries, regardless of their definitive treatment.

    Nondisplaced (Type I) or minimally displaced fractures in young children can potentially

    be treated with an above-elbow cast at 90 of flexion for 4 weeks. While it is often easiest to

    visualize displacement or angulation on the lateral radiograph, the Baumann angle on the AP

    radiograph can be a useful tool to identify and measure varus impaction. When there is varus

    angulation at the fracture site, strong consideration should be made for closed reduction and

    percutaneous pinning. More than 10 of varus malalignment (compared to the contralateral

    arm) is an indication for operative reduction and pinning. As a general principle, larger

    diameter pins convey better stability and are more effective at maintaining fracture reduction

    and alignment.

    Angulated fractures that maintain an intact posterior cortex, but have an anterior humeral

    line that passes anterior to the capitellum on the lateral radiograph (Type II) require

    reduction. These may become stable after closed reduction and casting at 90 of flexion. If

    more than 90 of flexion is needed to maintain reduction, then an operative reduction of the

    fracture with percutaneous pinning should be performed to minimize risks of complications

    associated with the increased elbow flexion required to maintain reduction in these injuries.

    Fractures that create significant displacement of the distal humerus (Type III) are

    particularly prone to neurovascular compromise. Closed reduction and percutaneous pinning

    is the preferred treatment for displaced fractures (Fig.5c and d). Fractures with displacement

    treated by closed reduction and casting have a higher incidence of residual deformity that

    those managed with operative reduction and pinning. After a careful clinical evaluation that

    finds no neurovascular injury, an operative fracture may be splinted and managed safely in a

    delayed fashion (within 24 h) while awaiting operative fracture reduction. Recent studies

    have shown that delayed surgical intervention does not increase complication rates or the

    quality of the reduction. However, it is still our feeling that the optimal management of a

    displaced fracture consists of an operative reduction and percutaneous pinning in an urgent

    manner and at least within 24 h. Certainly, a child with an operative fracture should be

    admitted for close observation of the neurovascular status while waiting for operative

    treatment.

    An open reduction is indicated in cases where the fracture is irreducible by closed

    methods or if the brachial artery has been compromised and requires exploration.

    Preoperative arterial insufficiency may be improved by operative reduction and pinning, in

    that a kinked brachial artery, draped over the distal end of the proximal fragment, may

    become patent after manipulative reduction of the fracture. Lastly, all open supracondylar

    fractures warrant a surgical debridement of the fracture followed by stabilization.

    While postoperative protocols vary from surgeon to surgeon, a typical regiment calls for

    a long arm, ulnar gutter-type splint or a split long arm cast to control elbow motion and

    forearm rotation for 4 weeks, followed by pin removal and early range of motion or

    continued splinting for additional 12 weeks. If a stable closed reduction and pinning of the

    fracture is achieved by an experienced pediatric orthopedic surgeon, follow-up may safely be

    delayed until the day of pin removal. However, if there is any uncertainty about fracture

    reduction or stability after pinning, the first follow-up visit should be within 7 days of

    surgery. This early follow-up for unstable fractures allows for a repeat closed manipulation

    and pinning if there has been a loss of reduction.

    Exercises are commonly prescribed to patients with a supracondylar fracture

    following confirmation that the fracture has healed, and that the orthopaedic specialist has

    indicated it is safe to begin mobilization. You should discuss the suitability of these exercises

    with your physiotherapist prior to beginning them. Generally, they should be performed 3

    times daily and only provided they do not cause or increase symptoms.

    - Elbow Bend to StraightenBend and straighten your elbow as far as possible pain free (figure 3). Aim for no more than a

    mild to moderate stretch. Repeat 10 times provided there is no increase in symptoms.

    - Forearm RotationsBegin this exercise with your elbow at your side and bent to 90 degrees (figure 4). Slowly

    rotate your palm up and down as far as possible pain free. Aim for no more than a mild to

    moderate stretch. Repeat 10 times provided there is no increase in symptoms.

    possible and comfortable without pain. Hold for 5 seconds and repeat 10 times.

    Complication

    EARLY- Vascular injury. The great danger of supracondylar fracture is injury to the brachial artery,

    which, before the introduction of percutaneus pinning, was reported as occurring in over 5

    percent of cases. Nowadays the incidence is probably less than 1 percent. Peripheral ischemia

    may be immediate and severe, or the pulse may fail to return after reduction. More commonly

    the injury is complicated by forearm oedema and mounting compartment syndrome which

    leads to necrosis of the muscle and nerves without causing peripheral gangrene. Undue pain

    plus one positive sign (pain on passive extension of the fingers, a tense and tender forearm,

    an absence pulse, blunted sensation or reduced capillary refill time) demands urgent action.

    The flexed elbow must be extended and all dressings removed. If the circulation does not

    promptly improve, then angiography (in the operating table if it saves time) is carried out, the

    vessel repaired or grafted and a forearm fasciotomy performed. If angiography is not

    available, or would cause much delay, then Doppler imaging should be used. In extreme

    cases, operative exploration would be justified on clinical criteria alone.

    - Nerve Injury. The radial nerve, median nerve (particularly the anterior interosseus branch) orthe ulnar nerve may be injured. Fortunately loss of function is usually temporary and

    recovery can be expected in 3 to 4 months. If there is no recovery the nerve should be

    explored. However, if a nerve, documented as intact prior to manipulation, is then found to

    have failed after manipulation, then entrapment in the fracture is suspected and immediate

    exploration should be arranged. The ulnar nerve may be damaged by careless pinning. If the

    injury is recognized, and the pin removed, recovery will usually follow.

    - Compartment syndrome. Increased interstitial pressure within a closed fascial compartmentcan lead to compartment syndrome. This increased pressure can result in compromised

    circulation to the nerves and muscles in that compartment. Elevated tissue pressure obstructs

    venous outflow from the compartment, which further contributes to the increased pressure

    and swelling. Ischemia occurs once the pressure rises above arteriolar circulation. Muscle and

    nerve tissue becomes damaged as soon as 46 h after the onset of abnormal pressures.The

  • 8/13/2019 Supra Con Diler

    14/20

    14

    first sign of compartment syndrome is disproportionate pain requiring increasing doses of

    pain medication. Other findings include sensory changes such as paresthesias, loss of active

    movements in the effected compartment, forearm tenderness, palpable tenseness of the

    muscles of the forearm (or arm), and pain with passive flexion or extension of the fingers. It

    is important to note that distal pulses and capillary refill are not reliable indicators of

    compartment syndrome. In young children the physical signs of compartment syndrome may

    be difficult to accurately assess. As a consequence, tissue pressure measurements should be

    obtained when the diagnosis is uncertain.

    LATE

    - Angular malunions of the distal humerus are a possible complication of supracondylarfractures. The remodeling potential of the distal humerus is somewhat limited due to the fact

    that the distal physis contributes only 20% to the growth of the distal humerus. Remodeling

    of the angulation in the sagittal plane can occur, but angular deformities in the coronal plane

    are less likely to remodelresulting in a cubitus varus or valgus deformity.

    - Cubitus varus, or gun-stock deformity, is the most common late complication ofsupracondylar fracture. This deformity is the result of fracture malunion and occasionally the

    partial growth arrest of the medial condylar physis. Proper anatomic reduction and fixation

    during initial management prevents malunion. Minor varus angulation is generally considered

    a cosmetic, rather than functional, deformity. A corrective osteotomy may be performed to

    improve clinically significant malunions

    Prognosis

    Patients with a supracondylar fracture usually make a full recovery with appropriate

    management (whether surgical or conservative). Return to activity or sport can usually takeplace in weeks to months and should be guided by the treating physiotherapist and specialist.

    In patients with severe injuries involving damage to other bones, soft tissue, nerves or blood

    vessels, recovery time may be significantly prolonged.

    Delayed treatment or wrong treatment (manipulated or massage by a traditional bone

    healer) of supracondylar fracture leads to malunion such as varus deformity, or gun stock

    deformity.

    Anatomy

    The humerus is the longest and largest bone of the upper extremity; it is divisible into a body

    and two extremities.

    Upper Extremity.The upper extremity consists of a large rounded headjoined to the body

    by a constricted portion called the neck, and two eminences, the greater and lesser

    tubercles.

    1. The Head (caput humeri).The head is directed upward, medialward, and a littlebackward, and articulates with the glenoid cavity of the scapula.

    2. The Anatomical Neck (collum anatomicum) is the line separating the head from therest of the upper arm.

    3. The Greater Tubercle (tuberculum majus; greater tuberosity).The upper surface isrounded and marked by three flat impressions: the highest gives insertion to the

    Supraspinatus; the middle to the Infraspinatus; the lowest one to the Teres minor.

    4. The Lesser Tubercle (tuberculum minus; lesser tuberosity).Above and in front itpresents an impression for the insertion of the tendon of the Subscapularis.

    5. The line separating the upper end of the humerus from the shaft is called the surgicalneck.

    The Body or Shaft (corpus humeri).The shaft is rounded in the upper half and triangular

    in the lower half. It has three borders and three surfaces.

    The Lower Extremity.The lower end of humerus forms the condyle which is expanded

    from

    side to side, and has articular and non articular parts.

    The articular part includes the following :

    1. The capitulum is rounded projection which articulates with the head of the radius.2. The trochlea is a pulley shaped surface. It articulates with the trochlear notch of the

    ulna. The medial edge of the trochlea projects down 6mm more than the lateral edge:

    this results in the formation of the carrying angle.

    The non articular part includes the following :

    1. The medial epicondyle is a prominent bony projection on the medial side of the lowerend. it gives attachment to the ulnar collateral ligament of the elbow-joint, to the

    Pronator teres, and to a common tendon of origin of some of the Flexor muscles of the

    forearm; the ulnar nerve runs in a groove on the back of this epicondyle. The

    epicondyles are continuous above with the supracondylar ridges.

    2. The lateral epicondyle is a small, tuberculated eminence, curved a little forward, andgiving attachment to the radial collateral ligament of the elbow-joint, and to a tendon

    common to the origin of the Supinator and some of the Extensor muscles.

    3. The lateral supracondylar ridge is a sharp lateral margin just above the lower end.4. The coronoid fossa is a depression just above the anterior aspect of the trochlea. It

    accommodates the coronoid process of the ulna when the elbow is flexed.

    5. The radial fossa is a depression present just above the anterior aspect of thecapitulum. It accommodates the head of the radius when the elbow is flexed.

    6. The olecranon fossa lies just above the posterior aspect of the trochlea. Itaccommodates the olecranon process of the ulna when the elbow is extended.

    CHAPTER IV

    SUMMARY

    Supracondylar fracture is a fracture of the distal humerus just above the epicondyles.

    Supracondylar fracture of the humerus are a common pediatric elbow injury that are

    historically associated with morbidity due to malunion, neovascular complications, and

    compartement syndrome.1There is 2 types of supracondylar fracture the extension type (95%)

    or posterior displacement type and flexion type (5%) or anterior displacement type. Gartland

    classification of extension fracture: type IUndisplaced, type II displaced with posterior

    cortical hinge intact , type IIIdisplaced with no cortical contact.

    The child will present with pain, swelling, and limited elbow range of motion

    (ROM). A displaced fracture in extension typically has an S-shaped deformity. Swelling can

    be very rapid. Younger children can present with the appearance of a dislocated elbow.In the

    laboratory result low hemoglobin may occur in severe bleeding, leucocytosis appear as an

    inflammatory responce because of the cell injuries or because of an infection. The

    radiographic study of the injured limb should include an anteroposterior (AP) and a lateral

    view of the elbow and any other sites of deformity, pain, or tenderness. On the AP view,

    Baumanns angle is commonly used to evaluate fractures as it maintains an estimation of the

    carrying angle (the varus or valgus attitude of the distal humerus and elbow).

    Complication of supracondylar fracture is defided in early and late complication. For

    early complication there are vascular injury, and nerve injury, and for the late injury there are

    malunion, cubitus varus deformity and elbow stiffness and myositis ossificans.

    Patients with a supracondylar fracture usually make a full recovery with appropriate

    management (whether surgical or conservative). In patients with severe injuries involving

    damage to other bones, soft tissue, nerves or blood vessels, recovery time may be

    significantly prolonged. Delayed treatment or wrong treatment (manipulated or massage by a

    traditional bone healer) of supracondylar fracture leads to malunion such as varus deformity,

    or gun stock deformity.
