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.

Background: The purpose of this study is to compare clinical and radiological outcomes between trans-acromial fixation with Kirschner's wire (K-wire) and AO locking hook plate fixation for acute acromioclavicular (AC) joint dislocation. Methods: This study included 61 patients who underwent either closed reduction and trans-acromial fixation with K-wire (group A, 23 patients) or open reduction and internal fixation with AO locking hook plate (group B, 38 patients). Pain on a visual analogue scale (VAS) score, the University of California Los Angeles (UCLA) shoulder score, the American Shoulder and Elbow Surgeons (ASES) score, and active range of motion (ROM) were used in the functional evaluation. For radiological evaluation, coracoclavicular distance (CCD) was measured on both clavicular anteroposterior view and compared between groups. Results: At one-year follow-up, no significant differences in VAS pain score, UCLA shoulder score, ASES score, and active ROM were observed between groups, despite five cases (22.7%, 5/23) of complication in group A. The side-to-side difference between normal and affected CCD was $2.4{\pm}2.2mm$ in group A and $0.2{\pm}0.7mm$ in group B. This difference showed a statistical significance between groups (p<0.001). Conclusions: For the treatment of acute AC joint dislocation, the K-wire trans-acromial fixation group showed a significantly greater CCD than the AO locking hook plate group. In addition, during the follow-up period, much higher incidence of complication related to implant was observed in the trans-acromial fixation group. Although clinical outcomes between groups were not significantly different, these results should be interpreted carefully.

Traumatic anterior dislocation of the shoulder is one of the most common directions of instability following a traumatic event. Although the incidence of shoulder dislocation is similar between young and elderly patients, most studies have traditionally focused on young patients due to relatively high rates of recurrent dislocations in this population. However, shoulder dislocations in older patients also require careful evaluation and treatment selection because they can lead to persistent pain and disability due to rotator cuff tears and nerve injuries. This article provides an overview of the nature and pathology of acute primary anterior shoulder dislocation, widely accepted management modalities, and differences in treatment for young and elderly patients.

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.

We report two cases of migration of K-wires from the acromioclavicular joint to the neck. A 73-year-old man complained of right shoulder pain for one month and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 27 years earlier. Another 56-year-old man complained of left shoulder pain and neck pain for 5 years and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 25 years earlier. In both cases, we took X-rays to look for the cause of shoulder pain and discovered broken and migrated K-wires in the neck. We removed the K-wires from the trapezius muscle and the paraspinal muscle respectively. K-wire fixation technique is simple and effective but should be followed up with X-rays periodically. In addition, we should warn patients of the possibility of migration of K-wire. And it is desirable for us to avoid using K-wire near major neurovascular structures like the sternoclavicular joint and the clavicle.

Eccentric muscle contraction is more effective than concentric and iosmetric muscle contraction in increasing muscle strength. Also, eccentric or concentric-eccentric training has greater effective in neural activation and muscle hypertrophy than concentric training. In some study, eccentric exercises have been shown to reduce pain and improve function on Achilles tendinopathy. The purpose of this study was to evaluate the effect of eccentric isokinetic exercise in a patient with dislocation of the tarsometatarsal joint by traffic accident. After eccentric isokinetic training, peak torque, average work, and average power were increased. Also, the patient was fully weightbearing with a pain free normal gait thus making good recovery.

Fractures at the lateral end of the clavicle inevitably require surgical treatment as there is high potential for delayed union or nonunion. Acromioclavicular dislocation also requires stable and solid fixation for healing, and surgical treatment is recommended for the maintenance of joint function. The hook plate maintains the biomechanics of the acromioclavicular joint, enabling early range of motion. Therefore, for the past 10 years, the hook plate has been widely used in distal clavicle fractures and acromioclavicular joint injuries. However, the hook plate is associated with several complications, such as proximal clavicle fractures, widening of the hook hole, rotator cuff tear, subacromial impingement, and often acromial fractures. We report on two unusual cases of acromion fracture after hook plate fixation in patients with distal clavicle fracture and acromioclavicular dislocation alongside a literature review.
