Lower limb injuries among motor vehicle occupants are relatively common and are one of the principle causes of permanent disability. The author has reviewed the current literature and his own experience as an orthopaedic surgeon and research accident investigator concerning lower limb injuries among motor vehicle occupants. An unreported series of knee, thigh, hip, pelvis injuries with indepth accident investigation is reported.Incidence rates for specific injury diagnoses are not available. Gross tabulations reveal that lower limb injury is second only to head injury in frequency among injured motor vehicle occupants. Lower limb injuries are possibly the commonest cause of permanent disability and impairment resulting from motor vehicle accidents.Accident investigation studies have identified the mechanisms of the more common lower limb injuries which are as follows: Treatment of lower limb fractures is necessarily prolonged because of the necessity for bone healing and rehabilitation of injured joints. Cast immobilization of 6 weeks to as much as a year may be necessary. Certain fractures are best treated by open reduction and internal fixation with plates and screws, intramedullary nails, circumferential wires and bands. Occasionally, immobilization in traction or external fixation with the use of trans-fixation pins extending trhough the skin into the bone, is necessary. Soft tissue damage and loss must be repaired or replaced by graft or substitution with an artificial implant. Minimum healing time is seldom less than 3 months, typically requires 6-12 months, and may extend as long as several years.Permanent disability frequently results from lower extremity injuries. Fractures extending into major joints,' the hip, knee and ankle frequently cause traumatic (degenerative) arthritis. Total joint replacement of the hip and knee, and fusion of the ankle are ultimately often necessary to provide even partial relief from such disability. Ligamentous injuries of the knee may lead to long term instability and traumatic arthritis. Deformities due to bone loss, malunion and infection are also common sequelae of more severe fractures of the lower limb.
