Intended Use

Intramedullary Hip Screws are indicated for intracapsular fractures of the femoral neck; trochanteric or subtrochanteric fractures; osteotomies for patients with diseases or deformities of the hip; hip arthrodesis; supracondylar fractures and distal femoral fractures using a supracondylar plate; ipsilateral femoral shaft/neck fractures; intertrochanteric fractures; femoral neck fractures; subcapital fractures; comminuted neck and shaft fractures; femur reconstruction following tumor resection; leg length discrepancies secondary to femoral inequality; and prophylactic nailing of impending pathologic fractures. Smith & Nephew, Inc. Intramedullary Hip Screws are for single use only.

Device Story

Intramedullary Hip Screw is a metallic bone fixation device; used for stabilization of femoral fractures and reconstruction. Device implanted by surgeons in clinical/OR settings; provides mechanical support to bone segments during healing. Operates via internal fixation; designed to withstand in vivo loading. Single-use device; provides structural stability to facilitate bone union and patient mobility. Benefits include fracture stabilization and correction of femoral deformities.

Clinical Evidence

Bench testing only; no clinical data provided. Mechanical test data indicates the device is equivalent to predicate devices and capable of withstanding expected in vivo loading.

Technological Characteristics

Metallic bone fixation appliance; single/multiple component design. Materials and design features are consistent with legally marketed predicate devices for orthopedic fixation.

Indications for Use

Indicated for patients with femoral fractures (intracapsular, trochanteric, subtrochanteric, supracondylar, distal, shaft/neck, intertrochanteric, subcapital, comminuted), hip deformities/diseases requiring osteotomy or arthrodesis, femur reconstruction post-tumor resection, leg length discrepancies, and prophylactic nailing for impending pathologic fractures.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.
