Abstract:

Background: The acromion clavicular joint dislocations are common injuries of the shoulder. The severity is dependentupon the degree of ligamentous injury. Surgical treatment is typically performed in higher grade acromioclavicularseparation with several static and dynamic operative procedures with or without primary ligament replacement.Methods: 47 patients with acute Rockwood type III, IV, and V injuries were treated surgically with LARS reconstruction.The success of technique was evaluated by radiographic outcomes for each patient at every follow-up visit (one,three, 12 months), while to assess pain reduction and clinical evaluation Visual Analogue scale score (VAS) andConstant-Murley score (CMA) was performed, respectively. An One Way Analysis of Variance (Kruskal-Wallis test), amultiple comparison Turket test, or a t-test (Mann-Whitney Rank Sum Test) were used when required.Results: Follow-up radiographs revealed maintenance of anatomical reduction in 41 patients, and no bone erosionshas been identified. In short-term joint functional recovery has been observed. Indeed, after 12 months pain on theVAS-scale in all groups decreased significantly (P < 0.05), and the CMS revealed a significant overall improvement(P < 0.05).Conclusion: These data demonstrate that the use of the LARS allows to provide stability to the joint and especially toensure its natural elasticity, relieving pain and improving joint function already one month post-surgery.Level of evidence: III

Comparison of Acute Acromioclavicular Joint Dislocation Treatment by Screw Fixation with and without Ligament Reconstruction

Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...

Complete dislocation of the acromio-clavicular joint.

(‘omplete dislocation of the acromio-clavicular joint is not a common injury. A review of the literature fails to disclose a carefully followed series numbering more than twenty-five identically treated cases. Treatment is indeed varied, and end-results uncertain. In the past four years we have been fortunate in encountering twenty-seven cases of complete acromio-clavicular dislocation (Fig. 1)...

Comparison of Results between Hook Plate Fixation and Ligament Reconstruction for Acute Unstable Acromioclavicular Joint Dislocation

BACKGROUND In the present study, we aimed to compare clinical and radiographic outcomes between hook plate fixation and coracoclavicular (CC) ligament reconstruction for the treatment of acute unstable acromioclavicular (AC) joint dislocation. METHODS Forty-two patients who underwent surgery for an unstable acute dislocation of the AC joint were included. We divided them into two groups accor...

Surgical treatment of chronic dislocation of the sterno-clavicular joint.

The costo-clavicular ligament is always ruptured in dislocation at the sterno-clavicular joint. Anterior, superior or posterior displacement of the medial end of the clavicle may occur. Acute dislocation usually responds to conservative treatment and operation is seldom required. Chronic, or recurrent, dislocation may cause pain and disability on strenuous activity and necessitate surgical trea...
