femur shaft fractures
TRANSCRIPT
Femoral Shaft FracturesDr. Ajay Alex
CMC, Ludhiana
Anatomy
Long tubular bone, anterior bowed forward and has oblique course from the neck to distal end.
Compartments of thigh Muscle of the thigh are arranged in three Compartments1-anterior compartment of thighContains the sartorius and the four large quadriceps2-medial compartment of thigh(gracilis ,pectineus, adductor longus, adductor brevis, adductor magnus, and obturator externus)
3-posterior compartment of thigh contain three large muscle termed the ‘”hamstring”Femur is surrounded by massive musculature ,which provide the blood supply to femur
Fracture Shaft Of Femur• A femoral shaft
fracture is a fracture of the femoral diaphysis occurring between 5 cm distal to the lesser trochanter and 5 cm proximal to the adductor tubercle
Epidemiology
-Common injury due to major violent trauma
-1 femur fracture/ 10,000 peoplemore common in people < 25 yr or >65 yr
-Motor vehicle, motorcycle, auto-pedestrian, fall from height, and gunshot wound
Mechanism Of Injury• In Young Adults, almost always the result of
high-energy trauma,– Motor vehicle accident– Gunshot injury, or– Fall from a height
• Pathologic fractures, especially in the elderly, commonly occur following a trivial fall• Stress fractures occur mainly in military
recruits or runners
Symptoms Diffuse pain or ache, and tenderness and swelling in the thigh or groin.
Bleeding and bruising in the thigh (uncommon).
Weakness and inability to bear weight on the injured leg.Paleness and deformity
Clinical Evaluation• A full trauma survey is indicated (ABC)• The patient is–Non ambulatory with pain–Variable gross deformity of thigh – Swelling,– Shortening of the affected extremity.
• A careful neurovascular examination is essential
• A careful assessment of hemodynamic stability is essential,Average expected Blood loss of 750-1500ml• Thorough examination of the ipsilateral hip
and knee should be performed• Knee ligament injuries are common,
however, and need to be assessed after fracture fixation
Associated Injuries
• Ipsilateral femur neck, intertroch, distal femur #s
• Patella, tibia, acetabular, pelvic ring #s• Soft tissue injuries of knee• Thoracic & abdominal injuries(5-15%)
X-ray Will confirm the diagnosis and establish the sites ,line ,extent and
displacement
• AP and Lateral views of the femur, hip, and knee
• AP view of the pelvis should be obtained
• Look for evidence of an associated femoral neck or intertrochanteric fracture, knee injuries
Winquist and Hansen , 1984
* Type 0 - No commination
* Type 1 - Insignificant butterfly fragment with transverse or short oblique fracture,
* Type 2 - Large butterfly of less than 50% of the bony width, > 50% of cortical contact
* Type 3 - Larger butterfly leaving less than 50% of the cortex in contact
* Type 4 - Segmental commination
AO classification
Management-paediatrics
Pavlik Harness for Age<6months
Hip Spica Castfor Age upto 5 years
Gallows Traction
PaediatricThomas Splint
Flexible Intramedullary Nail Fixation
Adults-Non operative
• Traction- Skeletal, thomas splint• Cast braces- uncommonly used
For patients in whom surgery needs to be delayed, temporary stabilisation with
Skeletal traction is required
Operative Fixation Options
• Intramedullary Fixation• Open Reduction and Plate Fixation• External Fixation
(For Open/ Infected Fractures)
Intramedullary Fixation
Plate Fixation
Indications for plating
• Patients wit extremely narrow medullary canal
• Fractures around or adjacent previous malunion
• Fractures extending proximally or distally into the pertrochanteric or metaphyseal region
• Ipsilateral neck fractures
External Fixation• Severe soft tissue
injuries• Contamination• Associated vascular
injuries• Polytrauma-temporary
method
COMPLICATION
1-GENERALBlood loss, shock ,fat embolism, and acut respiratory distress are common in high-energy injuries
COMPLICATION
2-Vascular injury3-Nerve injury-iatrogenic(femoral, sciatic, pudendal, peroneal)4-Thromboembolism5-Compartment syndrome(1-2%)6-Infection 7-Delayed union and non-union8-Joint stiffness, knee & hip pain9-Heterotrophic ossification
