The Role of Computed Tomography in Evaluating Intra-Articular Distal Humerus Fractures.

Computed tomography (CT) is often used to evaluate intra-articular distal humerus fracture patterns, but it increases radiation exposure and cost. We conducted a study to determine the effect of adding CT evaluation to plain radiographic evaluation on the classification of, and treatment plans for, intra-articular distal humerus fractures. Nine blinded orthopedic surgeons evaluated 30 consecutive fractures for classification and surgical approach.

Primary partial humeral head resurfacing: outcomes with the HemiCAP implant.

Background: Humeral head defects such as degenerative disease or avascular necrosis are often treated with stemmed hemiarthroplasty or total shoulder arthroplasty. Despite its historical and clinical significance, stemmed humeral head replacement poses inherent technical challenges to placing spherical implants at the anatomically correct head height, version, and neck-shaft angle.

Purpose: The aim of this study was to assess humeral head inlay arthroplasty as a joint-preserving alternative that maintains the individual head-neck-shaft anatomy.
