“…The locked posterior dislocation is accounted for about one-third of posterior dislocations that strongly can change the therapy and prognosis (6). In the Benhamida study, one close reduction out of three locked posterior dislocation was failed and open reduction and using a special technique for stability were needed in all three cases (9). In this report, open reduction, subscapularis transfer or the McLaughlin technique were used.…”

Introduction: Posterior shoulder dislocation associated with fracture of the lesser tuberosity is considered as a rare shoulder trauma. It can lead to the locked shoulder with a very high possibility of unsuccessful closed reduction. Case Presentation: In this case, the patient was a 30-year-old male motorcyclist with the right shoulder injury who had posterior shoulder dislocation with lesser tuberosity fracture. Early attempt for closed reduction was unsuccessful and led to iatrogenic brachial plexus injury. This patient is treated by open reduction and fracture fixation with screw. Subscapularis partial rupture was repaired. Finally, full stability was achieved. Conclusions: Fracture fixation plays a crucial role in stability after reduction. Several techniques have been suggested for surgical treatment including fixation with screw and the modified McLaughlin technique. Similar to the previous case reports, according to our experience, careful attention to the fracture concomitant with posterior dislocation is of the utmost importance.

“…Le traitement chirurgical des luxations postérieures de l’épaule par transfert musculaire est plus favorable, elle consiste au transfert du sous scapulaire avec comblement de l'encoche par le trochin ce qui oppose la surface arrondie ostéo-articulaire au bord postérieur de la glène lors de la rotation interne et évite aussi l'avalement de l'encoche lors de ce mouvement [ 2 , 3 ]. Ce transfert du sous scapulaire bride la rotation interne par tension du muscle qui se coude sur le bord antérieur de la glène lors du mouvement luxant.…”

La luxation postérieure de l’épaule constitue une lésion rare et un piège diagnostique et mettant en jeu le pronostic fonctionnel de l'articulation de l’épaule. Les signes cliniques et radiologiques des luxations postérieures de l’épaule ont été bien définis dans la littérature par Bernageau et Patte, mais elles passent le plus souvent inaperçues. Nous rapportons un cas de luxation postérieure de l’épaule chez un sujet sportif de 22 ans pratiquant le Hand-Ball, traité par la technique de transfert pédiculé du sub-scapulaire.

“…The diagnosis is often missed in the acute stage due to inadequate imaging or physical examination, unlike the high accuracy of Dugas sign in anterior dislocation [8][9][10]. Additionally, in terms of the limitation of shoulder function, some patients may only show external rotation dysfunction and abnormality on the X-ray of axial and standard anteroposterior views [11,12].…”

Background Posterior shoulder dislocation is an uncommon orthopaedics injury and is frequently missed or misdiagnosed, accounting for 2%-4% of all shoulder dislocations, and is associated with the reverse Hill-Sachs lesion. Once posterior shoulder dislocation develops into a chronic disease, it will bring a lot of trouble to the treatment, especially in repairing the humeral defects. Surgical strategies are also developing and innovating to deal with this injury, including transfer of subscapularis tendon or lesser tubercle, humeral rotational osteotomy, autogenous bone graft or allograft. Shoulder replacement seems to be the ultimate and only option when the injury becomes irreparable, although some studies have shown unsatisfactory follow-up results. Considering no gold-standard treatment for locked posterior shoulder dislocation, we described a novel modified McLaughlin procedure for locked chronic posterior shoulder dislocation and evaluated the functional outcomes. Methods This study included five locked chronic posterior shoulder dislocation patients with an associated reverse Hill-Sachs lesion, in which the compression surface covered 30–40% of the humeral head. The mean period from injury to receiving surgery was 11.6 weeks (6–24 weeks). All five patients underwent the modified McLaughlin procedure, mainly divided into three steps, including open reduction, transfer of the partial lesser tuberosity and artificial bone to repair the reverse Hill-Sachs defects. The kernel technique was to fix the transferred tuberosity with two lag screws and strengthen it with two Ethibond sutures. The Constant-Murley score (CMS), the range of shoulder motion and the complications were recorded to assess and compare the functional situation of the shoulder postoperatively and postoperatively. Results After an average of 19.8 months (12–30) of follow-up, the mean CMS improved to 85.8 ± 4.9 (79–91) compared with 46.0 ± 4.5 (40–52) preoperatively, which showed a significant difference (p = 0.001). In the final follow-up, all five patients showed no symptoms of shoulder instability, and there was no pain or limited activity in daily life, thus all patients were satisfied with the results. Conclusion Repairing the reverse Hill-Sachs lesion by transferring the partial lesser tuberosity combined with artificial bone fixed by lag screws and sutures can ensure shoulder stability and provide pain relief and good function in patients with locked chronic posterior shoulder dislocation associated with the humeral head defect.
