| ABSTRACT Background: To our knowledge, no previous studies have been conducted to comprehensively examine the morphology of the distal clavicle. The purpose of this study was to examine the distal clavicle morphology by assessing the dimensions and the angles of the distal clavicle in relation to the design of a potential distal clavicle prosthesis. Methods: Twenty cadaver clavicles were examined. The dimensions of the distal clavicular joint facet were directly assessed using a digital micrometer. Other angles and dimensions of the distal clavicle were assessed by taking measurements from the photographs of these clavicles taken from the anterior, the superior, and the inferior views. Radiographs were used to assess the cortices of the distal clavicle. Results: The average dimension of the distal clavicle joint facet was 14.7 mm (95% confidence interval [CI], 13.2Y16.1 mm) by 10.0 mm (95% CI, 9.2Y10.9 mm). The average dimension of the clavicle at 2 cm from its distal joint facet was 19.5 mm (95% CI, 17.6Y21.4 mm) by 10.0 mm (95% CI, 9.0Y11.0 mm). The average distal curvature length was 38.7 mm (95% CI, 36.7Y40.6 mm). The average distal curvature angle was 81 degrees (95% CI, 75Y87 degrees). The average normal length was 34.2 mm (95% CI, 30.8Y37.5 mm). The lateral tilting angle was measured to have an average value of 81 degrees (95% CI, 78Y84 degrees). The cortices of the distal clavicle were deficient. Conclusions: The results of this study suggest that the dimension of the distal clavicle joint facet, 13.2 to 16.1 mm (95% CI) by 9.2 to 10.9 mm (95% CI), would provide reference values for the size of the head piece of a distal clavicle prosthesis. The distal curvature length of 36.7 to 40.6 mm (95% CI) and the normal length of 30.8 to 37.5 mm (95% CI) would provide reference values for the length of the stem part of the prosthesis. The lateral tilting angle 78 to 84 degrees (95% CI) should be met to reproduce the natural distal clavicle anatomy.

“…There are disadvantages associated with surgical treatment including pain, infection and failure of the selected technique. Some surgeons feel that surgery is only indicated in the patient who continues to suffer pain after three to six months of nonoperative treatment and rehabilitation (Berkowitz et al, 1997).…”

The acromioclavicular joint is involved in four out of ten shoulder injuries. The joint is prone to injury due to its anatomy and relative lack of soft tissue cover. Sportsmen involved in contact sports are likely to suffer damage to the joint during their professional careers. Most subluxations of the joint can be treated nonoperatively whilst dislocations are generally treated operatively except in those individuals at significant risk of re-injury, for example, rugby players. This article looks at the anatomy and physiology of the acromioclavicular joint, injury classification and presents the current evidence regarding treatment options for these injuries.
