Summary

Posterior shoulder dislocation associated with reverse Hill-Sachs fractures is an uncommon injury; however, it can occur in 30-90% of cases following the first episode of posterior shoulder dislocation, potentially leading to secondary instability, glenohumeral reluxation, and early osteoarthritis. Currently, accurate diagnosis and appropriate treatment for these types of injuries represent a chal

Abstract

Posterior shoulder dislocation is a rare desease presentend in aproximately 4% of the total population with shoulder dislocation. This lession have mor than 50% of relation with reverse Hill Sachs Injury or fracture of the antero-medial portion of humeral head.
We present the case of a 39 years old man with a hooking reverse Hill Sachs Injury + anterior subscapularis tendon injury ISAKOS II, which was treated with open Mclaughlin technique.
This type of disease are not diagnosticaded in the emergency room, up to 80% have to wait to a orthoapedic valoration and specific imaging studies to reach a diagnosis.
We identify in magnetic nuclear resonance hooking mclaughlin type injury with loss of bone in more than 28.3% of articular surface according to Gerber method.
We realized an open Mclaughlin technique using a deltopectoral approach. We did a biceps long head tenotomy, reduction of glenohumeral articulation, we look up to the bone loss of 20x30 milimeters in anteromedial portion of humeral head, and perform a mclaughlin technique positioning a corckscrew 3.5 milimeters anchor and transosseous suture.
The patient was inmovilized for 3 weeks with a universal shoulder inmobilizer, and after that iniciate with pendular exercises, showing better functional outcomes and decreased pain using Constant-Murley score.
As a aconclusion, we demonstrate that open mclaughlin technique with the use combined of anchors and suture have excellent outcomes treating posterior shoulder dislocation with reverse Hill Sachs Injury.
