Arthroscopic evaluation for posterolateral rotatory instability of the elbow.

ABSTRACT:

Objective

The purpose of this study was to evaluate the sensitivity of three arthroscopic techniques for intraoperative assessment of posterolateral rotatory instability (PLRI).

Methods

The study was performed using six fresh frozen cadaveric upper extremities. The three arthroscopic tests were the modified ulnohumeral drive through test, the annular drive through test, and proximal radioulnar joint instrumentation. Sequential soft tissue sectioning was performed to create four stages of instability: baseline, transection of the anterior half of the lateral collateral ligament complex (i.e., the radial collateral ligament), transection of the posterior half of the LCL complex (i.e., the lateral ulnar collateral ligament), and finally the release of the common extensor origin
