Modified Mclaughlin procedure for neglected posterior dislocation of shoulder: short-term results

<p>Between 2017 to 2020, A prospective case series for assessment of short-term outcomes was carried out on 10 shoulders with 3 being bilateral cases and diagnosed as neglected posterior dislocation of shoulder at a tertiary care centre and treated with the Modified Mclaughlin procedure. All patients had articular defect ranging from 27-46% as confirmed with computerised tomography. All the surgeries were carried out by a single team of surgeons. After 24 weeks follow up of 10 shoulders with mean age 32 years, all patients were found to have excellent results in terms of ROWE and constant score. Patients had significant reduction in VAS score. Timely diagnosis of articular involvement plays a vital role in management for which computed tomography has a pivotal role. Depending upon the articular involvement, line of management is to be decided. So, it can be concluded that, in cases of articular defect &gt;25% following posterior dislocation of shoulder, better outcomes can be achieved with modified Mclaughlin procedure in terms of radiographic union and clinical scoring.</p>

Posterior Shoulder Dislocation with Engaging Reverse Hill–Sachs Lesion: A Retrospective Study of Ten Patients Treated with Arthroscopy or Open Reduction and Stabilization

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.

Posterior shoulder dislocation with reverse Hill-Sachs lesion. A technical note and report of two cases

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.

All-Arthroscopic McLaughlin's Procedure in Patients with Reverse Hill–Sachs Lesion Caused by Locked Posterior Shoulder Dislocation

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.
