An orthopaedic surgical instrument may include an elongated body with a proximal end and distal end. A clamp lever may be pivotally coupled to the proximal end of the elongated body. The clamp lever may be moveable between a locked position and an unlocked position. A biasing element may be configured to bias the clamp lever to the locked position.

Femoral surgical instrument and method of assembling same

An orthopaedic surgical instrument assembly includes a system handle configured to clamp a broach and femoral stem trial assembly. The system handle includes a clamp lever and a release lever both pivotally coupled to the system handle, and a leaf spring connecting the clamp lever and the release lever. When the release lever is moved from an unclamped position to a clamped position, the leaf spring is put in tension, and the clamp lever engages a flange of the broach, securing the broach to the system handle. Methods of assembling the system handle are described and claimed.

A surgical instrument extraction system includes a first extraction tool having a first body that extends between a first end and a second end. The first extraction tool has a first plurality of threads formed on the first end and a second plurality of threads formed on the second end. A second extraction tool has a second body that extends between a first end having a first diameter and a second end having a second diameter greater than the first diameter. The second extraction tool has a first plurality of threads formed on the first end and a second plurality of threads formed on the second end The first body of the first extraction tool is sized to extend through a bore of the second extraction tool. The second body of the second extraction tool is sized to extend through a bore of the first extraction tool.

Orthopaedic surgical instrument extraction system and method

A method of using an orthopedic surgical instrument assembly that includes an instrument handle configured to clamp a broach and femoral stem trial assembly. A depth stop is configured to removably couple to the instrument handle. When the broach and femoral stem trial are advanced into a medullary canal of a patient's femur, a substantially planar proximal surface of the depth stop is configured to engage the distal surface of the femur, determining the depth of the broach in the medullary canal. The proximal surface of the depth stop is parallel to the joint line, defining an oblique angle to the anatomical axis of the femur. The depth stop may be attached to the instrument handle at a number of positions to control the depth of the broach. The assembly may include a spacer plate removably coupled to the depth stop that distalizes the broach in the medullary canal.
