All-Arthroscopic, 270° Reconstruction of the Inferior Glenohumeral Ligament With Palmaris Longus Autograft.

Numerous factors play a role in anterior shoulder stability. The inferior glenohumeral ligament, especially the anterior band, is the main passive anterior stabilizer in the end range of motion. Surgical treatment of this pathology continues to be a challenge in patients with capsular deficiency, in whom the recurrence rate of soft-tissue arthroscopic repair increases significantly. There is not yet a fair solution for these patients without glenoid bone loss, in whom the poor tissue quality determines recurrent instability. We present an all-arthroscopic technique for reconstruction of the inferior glenohumeral ligament by means of palmaris longus autograft as an alternative to nonanatomic bone block procedures

Improved identification of unstable acromioclavicular joint injuries in a clinical population using the acromial center line to dorsal clavicle radiographic measurement.

BACKGROUND Accurate classification and subsequent management of acromioclavicular (AC) joint injuries remains a contentious topic. The updated Rockwood classification acknowledges "stable IIIA" and "unstable IIIB" injuries, a watershed accepted by ISAKOS and important in guiding clinical management. Traditionally, the coracoclavicular distance is used to classify these injuries, despite well-documented limitations. This study aimed to evaluate displacement in AC joint injuries by measuring both coracoclavicular (CC) distance and the newly proposed acromial center line to dorsal clavicle (AC-DC) distance, in a cohort of patients, and correlate the results between the 2 measurements and relationship to Rockwood grade. MATERIALS AND METHODS Ninety consecutive cases of AC joint injury were evaluated radiographically for Rockwood classification, CC distance on anteroposterior radiographs, and AC-DC distance on Alexander view radiographs. Inter- and intraobserver reliability for each measurement was calculated as well as correlation between the 2 measurement types and the degree to which each measurement accurately represented the Rockwood classification. RESULTS Although both CC and AC-DC measurements showed very high inter- and intraobserver reliability, the CC distance systematically underestimated the degree of AC joint displacement when compared with the AC-DC measurement as the severity of injury increased, particularly in the presence of posterior horizontal displacement such as that seen in Rockwood IV injuries. CONCLUSION The AC-DC measurement and use of the Alexander view provides the clinician with a more realistic appreciation of true AC joint displacement, especially in defining watershed cases (ie, IIIA/IIB/IV) and may better inform the decision-making process regarding management options and recommendations

Free Vascularized Fibular Graft for Reconstruction of the Lateral Clavicle: A Case Report and Review of the Literature.

CASE A 50-year-old female patient presented with significant (40%) bone loss of the lateral clavicle extending to the acromioclavicular (AC) joint, as a result of multiple, failed revision surgeries following a fracture-dislocation. She was treated with a free vascularized fibular graft and biplanar stabilization of the AC joint. At 4 years of follow-up, the patient had experienced resolution of painful symptoms with a Constant-Murley score of 72. CONCLUSIONS Reconstruction of large, lateral clavicle defects with a free vascularized fibular graft and biplanar stabilization of the AC joint may provide a satisfactory clinical outcome

High degree of consensus achieved regarding diagnosis and treatment of acromioclavicular joint instability among ESA-ESSKA members

Purpose To develop a consensus on diagnosis and treatment of acromioclavicular joint instability. Methods A consensus process following the modified Delphi technique was conducted. Panel members were selected among the European Shoulder Associates of ESSKA. Five rounds were performed between October 2018 and November 2019. The first round consisted of gathering questions which were then divided into blocks referring to imaging, classifications, surgical approach for acute and chronic cases, conservative treatment. Subsequent rounds consisted of condensation by means of an online questionnaire. Consensus was achieved when >= 66.7% of the participants agreed on one answer. Descriptive statistic was used to summarize the data. Results A consensus was reached on the following topics. Imaging: a true anteroposterior or a bilateral Zanca view are sufficient for diagnosis. 93% of the panel agreed on clinical override testing during body cross test to identify horizontal instability. The Rockwood classification, as modified by the ISAKOS statement, was deemed valid. The separation line between acute and chronic cases was set at 3 weeks. The panel agreed on arthroscopically assisted anatomic reconstruction using a suspensory device (86.2%), with no need of a biological augmentation (82.8%) in acute injuries, whereas biological reconstruction of coracoclavicular and acromioclavicular ligaments with tendon graft was suggested in chronic cases. Conservative approach and postoperative care were found similar Conclusion A consensus was found on the main topics of controversy in the management of acromioclavicular joint dislocation. Each step of the diagnostic treatment algorithm was fully investigated and clarified
