“…The techniques for reconstructing the coracoclavicular ligaments through transferring the coracoacromial ligament or using biological or synthetic grafts present the complication of loss of reduction. This has been found in up to 24% of the cases treated using the Weaver-Dunn method 15 , 22 . The lower resistance of the coracoacromial ligament and the change in direction of the force vector in relation to the coracoclavicular ligaments are the main causes of this complication (23) .…”

Objective: To evaluate the results from surgical treatment of 84 cases of acute acromioclavicular dislocation, using a posterosuperior access route. Methods: Eighty-four cases of acute acromioclavicular dislocation (grade III in the Allman-Tossy classification) operated between November 2002 and May 2010 were evaluated. The patients’ mean age was 34 years. The diagnoses were made using clinical and radiographic evaluations. The patients were operated by the same surgical team, within three weeks of the date of the trauma, using a posterosuperior approach to the shoulder to access the top of the base of the coracoid process for placement of two anchors, which were used in reducing the dislocation. The minimum follow-up was 12 months. The postoperative clinical-radiographic evaluation was done using the modified Karlsson criteria and the University of California at Los Angeles (UCLA) score. Results: 92.8% of the 84 patients treated presented good or excellent results, and 7.2% presented fair or poor results, using the UCLA assessment score. According to the modified Karlsson criteria, 76.2% were assessed as grade A, 17.9% as grade B and 5.9% as grade C. Conclusion: The posterosuperior access route to the shoulder is a new option for accessing the coracoid process and treating acromioclavicular dislocation, with clinical and radiographic results equivalent to those in the literature.

“…Although most common vascular injuries following AC joint stabilization may involve the great subclavian vessels [ 5 , 6 , 8 ], disruption of small vessels may also occur after modified Weaver-Dunn's procedure leading to osteolysis of the clavicle. Special care must be taken when performing modified Weaver-Dunn's technique not to elevate too much of periosteum from the lateral clavicle, since its main blood supply is provided by the periosteum, and also to avoid damage of clavicular and acromial branches of the thoracoacromial artery.…”

“…This technique provides adequate stabilization of AC joint with satisfactory clinical outcomes and low complication rate [ 2 – 4 ]. Most common complications include infection, clavicular erosion, neurovascular injury, continued pain, coracoclavicular calcification, keloids, cosmetic complaints, coracoid fracture, aseptic foreign-body reaction, AC osteoarthritis, or AC joint instability [ 4 – 8 ].…”

Distal clavicle osteolysis after acromioclavicular joint stabilization has only been described after the use of hardware for clavicle stabilization or synthetic graft causing a foreign body reaction. This paper reports a very rare case of distal clavicle osteolysis after modified Weaver-Dunn procedure for the treatment of chronic acromioclavicular joint dislocation. The paper also provides a comprehensive review of complications of this surgical technique and discusses a potential vascular etiology and preventive strategies aimed at avoiding clavicle osteolysis.

“…Commonly used techniques for management of ACJ dislocation include: (1) fixation of ACJ using wires/screw/sutures/hook plate, etc., which can be done along with repair of ligaments, (2) coracoclavicular fixation using screw/anchors/free tendon graft with ACJ reconstruction, and (3) excision of distal part of clavicle along with coracoclavicular ligament reconstruction, especially in arthritic joint. 5 6 7 8 9 However, the best operative treatment for ACJ reconstruction remains debatable. 5 9 10 11 …”

Background:The debate about the ideal surgical procedure for acromioclavicular joint (ACJ) dislocation is still unresolved and newer techniques are being evolved continuously. The present study evaluates functional outcome of ACJ reconstruction using the modified Weaver Dunn procedure.Materials and Methods:35 patients (26 males, 9 females) with ACJ dislocation, between the age group of 18–48 years (mean age 31 years), were operated using modified Weaver Dunn procedure at our center from May 2005 to June 2010. The dominant side was involved in 25 patients (22 right, 13 left). The mean period from the time of injury to the surgery was 14 days (range 4–26 days). All the patients were assessed with Oxford shoulder score and the time required to return to preinjury level was recorded.Results:At the mean followup of 95 months (range 72–120 months), the mean Oxford Shoulder Score improved from 25 ± 7.2 to 43 ± 6.9. 85% (30 out of 35) patients had satisfactory results, while 15% (5 out of 35) had mild shoulder dysfunction using this scoring system. Five patients had radiological evidence of Grade 2 ACJ subluxation. Out of these five patients, two developed ossification around the coracoclavicular ligament. Three patients had intermittent mild pain without any functional disability, and one had a moderate restriction of shoulder movements.Conclusion:ACJ reconstruction, using the modified Weaver Dunn procedure in ACJ dislocation, is a reproducible procedure and provides a good functional outcome.
