The authors present a case of transient postoperative inferior subluxation of the shoulder after arthroscopic surgical stabilization for recurrent anterior dislocation. The patient was a 61-year-old woman with myasthenia gravis (MG). The first anterior shoulder dislocation occurred because of a fall to the ground. Despite a successful closed reduction, two more dislocations occurred in 3 weeks. Magnetic resonance imaging revealed an anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion, an engaging Hill-Sachs lesion, and large tears of the supraspinatus and infraspinatus tendons. The patient underwent arthroscopic rotator cuff repair and ALPSA repair with a remplissage procedure. Intraoperatively, no tendency for instability was found; however, a widened glenohumeral joint space and inferior subluxation of the humeral head without functional compromise was observed on the day after surgery and disappeared spontaneously on radiographs 2 weeks later. To the authors' knowledge, this is the first report documenting the occurrence of transient postoperative inferior subluxation of the shoulder in a patient with MG.

Mechanism of the peroneal tendon dislocation is mainly the ankle trauma and commonly caused by severe peroneal tendon contraction at ankle dorsiflexion state. Peroneal tendon tears are frequently combined in recurrent dislocation. The peroneal tendon dislocation from the fibula groove can be confirmed with ultrasound scanning. Recurrent dislocation needs surgical treatment and usually gains good clinical outcome with fibula groove deepening procedure. Tibialis anterior tendon rupture is frequently found in old age but active patients who had tendency of tendon weakness due to chronic tendon attrition, repeated steroid injection, diabetic tendinopathy or inflammatory arthropathy.

We report 4 patients who developed change of occlusion which seemed to be related to anterior disc dislocation without reduction, but there was no distinct evidence of condylar destruction or collapse. They experienced sudden occurrence of occlusal change, anterior open bite in 2 patients, lateral CR-CO discrepancy in 1 patient, and anteroposterior CR-CO discrepancy in 1 patient. Also, this report is to find out if there is a relation between sudden occurrence of occlusal change and anterior disc dislocation without reduction.

Pure anterior bilateral shoulder dislocations are rare clinical features, especially in traumatic forms. They are most often posterior, occurring during an epileptic seizure. Few cases are described in the literature, and the mechanism varies from case to case. We report a specific case of pure bilateral anterior shoulder dislocation in a 29-year-old judo player following an accident during his training and discuss the circumstances, mechanism, treatment, and prognosis.

The glenohumeral joint is one of the most commonly dislocated joints. When dislocated, the humeral head typically moves anteriorly and medially within the soft tissues adjacent to the glenoid. We present a case of a 64-year-old female who presented with a locked anterior shoulder dislocation with impaction of the humeral head onto the coracoid. To our knowledge, this is the first reported instance of humeral head impaction onto the coracoid causing the shoulder dislocation to be irreducible by closed means. Complications of this dislocation can include humeral head deformity, pseudoparalysis, brachial plexus injury, and significant pain.

Four patients with shoulder problems that were traumatic in etiology presented to us with delays in seeking care ranging from 6 to 12 weeks due to the coronavirus disease 2019 (COVID-19) lockdown. The care of three cases (a 3-month-old neglected anterior shoulder dislocation with a greater tuberosity fracture in a 30-year old man, a 3-month-old neglected anterior shoulder dislocation in a 17-year old boy, and a 2-month-old neglected greater tuberosity fracture in a 31-year old man) was delayed due to the lockdown and the ensuing travel restrictions, while that of one case (a 6-week-old fracture-dislocation of the proximal humerus in a 55-year-old woman) was delayed because the patient was undergoing treatment for COVID-19 at the time of injury. This report intends to present the exceptional circumstances around these cases. The unique treatment challenges and their outcomes are also described to advise the surgeons of the nuances and difficulties in treating these injuries.

Purpose: These case reports have been prepared to highlight the uncommon occurrence of anterior shoulder dislocation after an epileptic seizure, the recognition of which is important as this type of injury is associated with bony lesions and a high incidence of recurrence. Materials and Methods: We report two cases of recurrent anterior dislocation of the shoulder due to grand mal epilepsy. These cases were treated as usual anterior dislocations of the shoulder, and were regularly followed to detect any recurrence of shoulder instability. Results: Outcome of the surgery in the two cases was different because of the differences in seizure control. In the patient in whom seizures were well-controlled, there was no recurrence of instability, while the patient with poorly controlled seizures developed a recurrence of the dislocation following shoulder repair. Conclusion: The authors emphasize the need to control seizures in order to prevent injury recurrence in this subset of patients.

Purpose: In the traumatic anterior shoulder instability, the laxity of joint capsule and ligament is frequently demonstrated. Although a arthroscopic procedure to address anterior instability with joint capsular redundancy have generally provided good results, its recurrence rate is higher than open procedure. By reducing the capsular redundancy, thermal shrinkage is likely to improve the outcome of arthroscopic anterior stabilization. The objective of this study was to evaluate additional thermal capsular shrinkage as a treatment of joint capsular redundancy in anterior shoulder instability. Materials and Methods: From March 1999 to June 2000, 25 shoulders of 23 patients of recurrent anterior shoulder dislocation underwent arthroscopic Bankart repair with shrinkage procedure. The mean follow up was 29 months and average age at the time of operation was 26 years. Of these patients, 20 were male and 3 were female who had been experienced the average 8 times of dislocation before operation. Thermal shrinkage alone without Bankart repair was performed in two cases who did not have Bankart lesion. The clinical result was evaluated in according to Modified Rowe Score. Results: The Modified Rowe Score was improved from preoperative 35 points to postoperative 88 points. None of cases showed recurrence of dislocation. But, in two cases, temporary sensory hypesthesia of the axillary nerve was developed and in two cases of postoperative stiffness, arthroscopic capsular release and brisement were performed. Conclusion: Additional capsular shrinkage in arthroscopic technique to address recurrent anterior shoulder instability could treat effectively the capsular redundancy.

Purpose: We compared the results of open and arthroscopic Bankart repair in traumatic recurrent anterior dislocation ,3f the shoulder. Materials and methods: We analysed 7 cases underwent open Bankart repair (group I) and 13 cases underwent arthroscopic Bankart repair (group Ⅱ). The average follow-up period was 68.1 months (51-113 months) in group I and 41.1 months (16~57 months) in group Ⅱ. All patients in group I and Ⅱ were non-athletes. We analyzed statistically objective evaluation, such as the stability of shoulder joint, the range of motion, pain, impaired throwing, Bankart rating system by Rowe and subjective evaluation, visual analog scale (VAS) between two groups. Results: In terms of dominant and non-dominant shoulders, the age at initial episode of dislocation, the elapsed time from injury to surgery, the number of preoperative dislocations associated with susceptibility to apprehension. respectively, there was no statistically significant differences between two groups. In group I the average Rowe's scortls was 84.3 and 3 cases (43%) had excellent results,4 cases (S7cfo), good ones. In group H the average Rowe's scores was 87.3 and 7 cases (54%) had excellent results,6 cases, good ones. There was tendency to show more excellent results in group ll, but there was no statistically significant differences. The average VAS were 90.3 points in group I and 88 points in group Ⅱ, which showed also no statistically significant differences. Conclusion: Open and arthroscopic Bankart repairs had no significant difference and showed also good results in travinatic recurrent anterior dislocation of shoulder.
