Abstract
Hip fractures are a leading cause of disability among the elderly. Treatment goals for this patient population include early mobilization with restoration of the anatomic alignment of the proximal part of the femur and maintenance of the fracture reduction. More than 90% of hip fractures in patients after the 5th decade of age are intertrochanteric fractures with 20-30% of these cases experiencing complications and a mortality rate of approximately 17%. Intertrochanteric fractures of the femur occur between the greater trochanter, the attachment site to the hip abductor and extensor muscles, and the lesser trochanter, the attachment site of the hip flexor muscle. Operative treatment is the best option in most cases of hip fractures. There are several devices that may be used for fracture fixation. The Dynamic Hip Screw (DHS) is a screw that allows for controlled dynamic sliding of the femoral head and is used to fix both the femoral head and the device to the shaft of the femur. The dynamic compression allows the weight-bearing stresses to stabilize the femur so that it may undergo remodeling and proper fracture healing. After 30 weeks, 75% of the patients had their normal function restored.
