Computed tomography measurement of humeral head retroversion: influence of patient positioning.
For accurate humeral head arthroplasty, the surgeon needs to know some geometric data, such as, for example, the retroversion angle of the humeral head. Only a few reports have described and evaluated the use of computed tomography (CT) to measure humeral head retroversion. The humerus position relative to the roentgen beam is variable from one subject to another depending on the patients' morphology. ⋯ Our study tries to clarify technical problems that occur during CT examination. Geometric considerations that can modify the measurements are presented. A reliable method of humeral head retroversion angle measurement is recommended, which could be useful to the shoulder surgeon.

The use of a blade plate and autogenous cancellous bone graft in the treatment of ununited fractures of the proximal humerus.
Stable internal fixation is essential to obtain healing of an ununited fracture of the proximal humerus. Standard plate and screw fixation may be inadequate to secure a small, osteopenic proximal fragment. We used blade plates and autogenous cancellous bone graft to repair ununited fractures of the proximal humerus in 25 patients (19 women and 6 men) with a mean age of 61 years. ⋯ Objective and subjective instruments documented substantial functional improvement in patients with healed fractures. The results were classified as good or excellent in 20 of 25 patients, and few complications were encountered. Blade plate fixation facilitates successful treatment of ununited fractures of the proximal humerus.
