#### DEVICE INFORMATION:

### INTENDED USE:

Trochanteric reattachment whenever the trochanter is osteotomized in any of the procedures listed below.

- 1. Primary total hip arthroplasty
- 2. Revision total hip arthroplasty
- 3. Any procedure using anterolateral or lateral approaches

#### DEVICE DESCRIPTION:

The Cabling System Trochanteric Hook is made of Ti-6Al-4V. The trochanteric hook is used in conjunction with 2.0mm diameter cobalt chrome cables and cobalt chrome clamps from the Smith & Nephew Orthopaedics Cabling System (K031162). The trochanteric hook features one hook to attach to the trochanter and one hole to allow a cable to be routed through the device. The cable is routed through the hole in the device and around the femur. The cable will be tensioned and secured with a clamp. The hook is designed to prevent proximal migration of the trochanter. The device is intended for single use.

## SUBSTANTIAL EQUIVALENCE INFORMATION:

The Cabling System Trochanteric Hook is similar to the Smith & Nephew Orthopaedic Cabling System Trochanteric Grip (K031162) in that both devices are used with the same cables and clamps for trochanteric reattachment whenever the trochanter is osteotomized. The grips in the predicate system feature two hooks to attach to the trochanter, multiple holes to allow cables to be routed through the grip and clamps to secure the cables. The Cabling System Trochanteric Hook features one hook to attach to the trochanter and one hole to allow a cable to be routed through the device and a clamp to secure the cable.

The Cabling System Trochanteric Hook is similar to the Howmedica Dall-Miles Cable Grip (K984432), Pioneer System Greater Trochanteric Reattachment Device (K961267) and the Biomet BMP Cable System (K982545) in that all devices are used with cables and clamps for trochanteric reattachment whenever the trochanter is osteotomized.

The Cabling System Trochanteric Hook is similar to the Smith & Nephew Hook Piate in that both devices are used for trochanteric reattachment whenever the trochanter is osteotomized. The trochanteric hook is used with cables and clamps to secure the bone. The hook plate is used in conjunction with screws to secure the device to the bone.
