Various exemplary embodiments relate to a method of performing an anterior approach hip replacement. The method may include: exposing a surgical site including the femoral neck and acetabulum using a plurality of retractors secured to the plurality of accessory arms; cutting the femoral neck to remove the femoral head; preparing the acetabulum for insertion of an acetabular cup; preparing the femur for insertion of a femoral implant by lifting the femur using a femur hook and the femur distractor; and closing the surgical site. In various alternative embodiments, the method may include using a lesser trochanteric retractor coming from a direct medial approach and a greater trochanteric retractor coming from a lateral, posterior, proximal approach.

Surgical process for anterior hip replacement

A retractor assembly has a first clamp adapted to be mounted to a table, a first vertically oriented post supported by the clamp, a first main arm mounted for at least one of angular and lateral movement relative to the first post, and lockable in a selected position, and a tree assembly configured at one end of the second post. The tree assembly has at least two accessory arms, with each accessory arm having a first ball joint on a first end, and a pivot lock knob at an immediate portion, and each accessory arm having a second end configured to accept the mounting of a retractor to the accessory arm. The retractor assembly may also include a J-shaped hook mounted to a ratcheting linearly movable distractor assembly and trochanteric retractors mounted to the accessory arms for femoral elevation and exposure.

Anterior hip replacement retractor assembly

Various exemplary embodiments relate to a method of performing an anterior approach hip replacement using a retractor assembly. The method may include: providing a retractor assembly including a first vertical post, a plurality of accessory arms mounted to the first post, a second vertical post, and a femur distractor mounted to the second post; exposing a surgical site including the femoral neck and acetabulum using a plurality of retractors secured to the accessory arms; cutting the femoral neck to remove the femoral head; preparing the acetabulum for insertion of an acetabular cup; preparing the femur for insertion of a femoral implant by lifting the femur using a femur hook and the femur distractor; and closing the surgical site. In various alternative embodiments, the retractors may include a lesser trochanteric retractor coming from a direct medial approach and a greater trochanteric retractor coming from a lateral, posterior, proximal approach.

A connector for a surgical retractor is shown. The connector includes a body member having an opening for receiving a nipple of a retractor blade. The connector also includes a retainer pivotally attached to the body member between an open position and a closed position. A lock mechanism locks the retainer in the closed position so that the nipple of the retractor blade is locked in the connector.
