The Impact

This study compares two surgical techniques used to treat patients with posterior shoulder dislocation with an engaging reverse Hill–Sachs lesion. We assessed ten patients who were treated at the Surgical Orthopedic and Traumatological Institute (ICOT) of Latina and the Clinic of Orthopedic and Traumatological Surgery of the ASST Sette Laghi of Varese between 2016 and 2019. The patients were divided into two groups: the first comprising six patients who underwent the open surgery McLaughlin procedure as modified by Neer, the second including four patients who underwent the arthroscopic McLaughlin procedure. All patients received postoperative rehabilitation to achieve the best possible functional recovery of the affected shoulder. We then assessed the shoulder range of motion, the pain level, and the impact on quality of life with four tests: the Constant Scale, the Simple Shoulder Test (SST), the OXFORD Scale, and The University of California—Los Angeles (UCLA) Shoulder Scale. The mean scores of the first group were: 81.3 ± 9.8 SD (Constant Scale), 10.8 ± 1.06 SD (SST), 42.5 ± 5.4 SD (Oxford Scale), 30.8 ± 3.02 SD (UCLA Shoulder Scale); we calculated the following mean scores in the second group: 80.25 ± 4.1 SD (Constant Scale), 11.5 ± 0.8 SD (SST), 42 ± 4.06 SD (Oxford Scale), 32 ± 2.9 SD (UCLA Shoulder Scale). We found no significant differences between the two groups.

Mclaughlin Procedure

Abstract Purpose This study aims to investigate the clinical and functional outcomes of the all-arthroscopic McLaughlin procedure in a clinical series of patients suffering by neglected locked posterior shoulder dislocation. Methods A retrospective clinical study based on prospectively collected data was conducted in a single center regarding 10 patients with neglected locked posterior shoulder dislocation and concomitant reverse Hill–Sachs lesion, who were treated with the all-arthroscopic Mclaughlin procedure. The average humeral bone defect was 39 ± 7% according to the preoperative computed tomography evaluation. The mean time of follow-up was 77 ± 16 months (range, 63–104 months). Results No patient had suffered a new dislocation, whereas all of them were satisfied with the surgical outcome and returned to their previous activities of daily living. External rotation was restored to every patient studied from 0 degrees at the baseline. At the last follow-up, the median external rotation beside the body was 90 degrees (range, 50–90 degrees; p < 0.01) and the respective measurement at 90 degrees of abduction was 90 degrees (range, 80–90 degrees; p < 0.01). The active forward flexion was increased (p < 0.01), from 60 degrees (range, 30–180 degrees) at the baseline to 180 degrees (range, 160–180 degrees) at the last follow-up and the internal rotation was gained (p < 0.01) from the level of buttock (range, lateral thigh–T12) at the baseline to the T11 level (range, T7–L3) at the last follow-up. The median UCLA score was increased from 8 (range, 4–22) to 35 (range, 33–35; p < 0.01) and the Oxford instability score from 5 (range, 3–16) to 46 (range, 43–48; p < 0.01), respectively. Conclusion The arthroscopic McLaughlin procedure in substantial reverse Hills–Sachs lesion caused by locked posterior dislocation leads to excellent clinical and functional results in the long-term follow-up. Level of Evidence This is a therapeutic study, case series with no comparison group, Level IV.

Objectives: A 32 year old man who was admitted to the emergency department with serious pain and absent movement of the right upper extremity due to passing the ball in a basketball game. He had no shoulder dislocation in his medical history. The right shoulder position was flexion and adduction. The shoulder range of motion was restricted and the neurovascular examination was intact. Posterior shoulder dislocation was diagnosed in radiographs.The aim of the study is pointed out an unusual mechanism of the posterior shoulder dislocations which is related microtrauma. The main problem in treatment of this kind of dislocation is correct and timely diagnosis. Methods: After diagnosing the posterior shoulder dislocation, we reducted the shoulder joint immediately and immobilized in abduction and external rotation with Velpeau bandage. We took radiographs and computerized tomography to confirm the reduction of the joint and diagnose the additional bone pathology. Reverse Hill Sacks lesion was diagnosed. Two weeks later after diagnosing passive range of movement exercises were applied. Magnetic resonance imaging was done to diagnose the additional pathology. Results: There was no spesific finding in radiographs and reverse Hill Sachs lesion and anterior labral tear were determined in magnetic images finding. Conclusion: Shoulder joint dislocations are the most seen pathology in the emergency department. On the other hand posterior shoulder dislocations are less common than anterior dislocations, but more commonly missed. Posterior shoulder dislocations are caused by high energy trauma, seizures, electric shocks and microtrauma.

Modified Mclaughlin Procedure

Posterior shoulder dislocation (PSD) with a reverse Hill-Sachs lesion is a rare injury with challenging management. This article is a technical note, describing the combination of both, modified McLaughlin procedure with posterior Bankart repair, for the surgical treatment of traumatic PSD associated with a substantial reverse Hill-Sachs lesion. Two patients with mid-term follow-up are presented. Approaching and repairing both sides of the joint, balance and congruency are restored, the humeral head is centralized in the glenoid and the patient starts early mobilization and rehabilitation safely.

The Veil

<p><strong>Objective.</strong> To describe a new radiographic sign, “veil of obscuration”, associated with posterior glenohumeral joint (shoulder) dislocations and determine its incidence and validity compared to other known classic radiographic signs.</p><p><strong>Methods.</strong> Four-year retrospective study identified 30 acute posterior shoulder dislocation patients. Radiographs reviewed in consensus by 2 musculoskeletal radiologists for the “veil of obscuration”, seen on AP shoulder radiographs and representing a comminuted fracture of the lesser tuberosity projecting over the humeral head or glenohumeral joint. Incidence of this radiographic sign of posterior glenohumeral joint dislocation in addition to other previously described classic radiographic signs, and association with other fractures, surgery, and mechanism of injury were evaluated. Continuous data was analysed with student t-test and categorical data with Chi-Square test.</p><p><strong>Results. </strong>There were 20 right and 10 left posterior shoulder dislocations. Majority of injuries resulted from vehicle crash (44%). In most cases, reverse Hill-Sachs lesion (83%) and fixed internal rotation of the humeral head (76%) were present, followed by trough line (43%) and “veil of obscuration” (40%). Trough line was seen in significantly more major trauma and vehicle crashes (78% and 46%; P=0.015), while “veil of obscuration” was seen in more seizures (86%; P=0.037) and in all surgical patients.  No significant difference in presence of other classic radiographic signs in regards to surgery.</p><p><strong>Conclusion. </strong>The newly described radiographic sign of posterior shoulder dislocations named the “veil of obscuration” has comparable incidence as other classic radiographic signs and may be useful in the recognition and diagnosis of these injuries.</p>
