RESUMEN
Posterolateral corner injuries are a severe and often unrecognized pathology. Injuries to these structures are difficult to identify using magnetic resonance images. Physical examination tests including the dial test, frog-leg test, and varus stress test can be difficult to perform. In addition it is difficult to correctly evaluate the results in a multiligament injury setting. The correct diagnosis of this pathology is essential to determine the proper treatment and improve outcomes. Furthermore, failure to recognize this pathology is associated with a high risk of failure following isolated anterior cruciate ligament reconstructions. The purpose of this Technical Note is to present an alternative method for the evaluation of posterolateral corner injuries using radiographic images.
RESUMEN
Acromioclavicular (AC) joint instability is a fairly common and particularly limiting injury that may result in persistent pain and reduced quality of life. In most cases, conservative management is successful. However, in the case of a severe AC joint dislocation, surgical intervention may be warranted. Previous surgical techniques for treatment of AC joint instability include screw fixation between the coracoid and clavicle, coracoacromial ligament transfer from its acromial insertion to the clavicle, and reconstruction of the coracoacromial and/or coracoclavicular ligaments. The purpose of this Technical Note is to describe our preferred technique for the treatment of a high-grade AC dislocation through coracoacromial ligament transfer to the lateral clavicle and nonabsorbable suture fixation between the coracoid process and clavicle.
