SUMMARY: This study describes the distribution of the normal bone mass in the mature human ulna, as knowledge of distribution may provide information to orthopaedic surgeons for the treatment of such fractures while advancing the understanding of the responses of osteosynthesis elements during bone repair. A random sample of 41 dry ulnas was studied with a DXA system using a Norland XR-26 densitometer. Two projections were performed, lateral and antero-posterior. In both projections five regions of interest (ROI) were selected: proximal (ROI 1), proximal-intermediate (ROI 2), intermediate (ROI 3), distal-intermediate (ROI 4) and distal (ROI 5). All statistical calculations were performed using Stat graphics Plus (version 5.1) and SPSS (version 15.0). Bone mineral density (BMD) and bone mineral content (BMC) were calculated. Paired data were analysed using parametric Student t-Test to compare BMD and BMC in every region in both projections. DXA show that the higher BMD is in the proximal-intermediate region (ROI 2). The higher BMC is found in the proximal region (ROI 1). Lower BMD and BMC are found in the distal region (ROI 5). The total BMD shows significant statistical differences (p≤0.001), which indicates the heterogeneous nature of the distribution of bone mass in the studied bone. Bone densitometry, measured by the DXA technique, is useful for assessing trabecular architecture of the human ulna.

“…Semiconstrained designs are usually used, allowing a certain degree of valgus/varus of the ulnar component in the hinge mechanism. One of the complications of these TEA at follow-up is wear of the polyethylene bushings in the hinge, and axle failure [5][6][7][8][9][10]. We report the case of repeated failure of the axle component due to excess valgus in a patient 8 years after initial TEA for nonunion of a supracondylar fracture of the distal humerus and propose treatment.…”

a b s t r a c tSemiconstrained (linked design) total elbow arthroplasty is indicated in a wide variety of cases. Long-term survival is better than with non-linked prostheses. However, mechanical failure of the hinge mechanism is a complication that may occur during follow-up. We report a case of failure of the axle assembly of a Coonrad-Morrey elbow prosthesis 8 years after implantation for nonunion of a supracondylar distal humerus fracture. Initial revision surgery included changing the axle and the polyethylene bushings. Revision surgery was necessary 1 year later when the axle failed again. A custom-designed locking axle had to be used to stabilize the hinge mechanism. After 3 years follow-up, the hinge was intact, there was no loosening of the components and function of the elbow was good.
