## Indications for use
The Trauma Internal Fixation System is used for fracture fixation in the proximal and distal regions of the femur. In particular, indications for use in adult and pediatric patients are as follows: Adult indications: 1. Intracapsular fractures of the femoral neck. (For high subcapsular fractures it may be more prudent to select a prosthesis in lieu of internal fixation to reduce the risk of a nonunion or avascular necrosis of the femoral head). 2. Trochanteric or subtrochanteric fractures with appropriate additional postoperative precautions about weight bearing and more than sedentary activity. 3. Osteotomies for patients with diseases or deformities of the hip. 4. Hip arthrodesis. 5. Supracondylar fractures and distal femoral fractures using a supracondylar plate. 6. Ipsilateral femoral shaft/neck fractures (IMHS only). Pediatric indications: 1. Congenital coxa vara. 2. Congenital dislocation of the hip. 3. Subluxation or dislocation secondary to neurologic disorders such as cerebral palsy, myelomeningocele, poliomyelitis, etc. Usually valgus-anteversion deformities. 4. Coxa plana (Legg-Calve-Perthes disease) for containment of the head completely within the acetabulum.
