“…They are more frequently found in impacts with the humerus, and their effect on the stability of the elbow is proportional to the amount of fractured coronoid. They are also associated with radial head fractures (Weber et al, 2009). …”

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.

“…These markers identified the landmarks where cartilage thickness was to be measured. 23,38 The coronoid landmarks were as follows: coronoid tip, medial aspect of coronoid tip, lateral aspect of coronoid tip, trough in anteromedial facet, trough in anterolateral facet, point above sublime tubercle, ridge in anteromedial facet (between tip and sublime tubercle), transverse groove at guiding ridge (point distal to bare area), and midpoint along guiding ridge (between bare area and coronoid tip) (Fig. 1).…”

“…1,3,38 Despite the crucial role of the coronoid process in elbow stability, little information on the detailed anatomy of the coronoid process is available in the literature. Of special interest in this study is the proposed significance of the articular cartilage overlying the coronoid process in relation to coronoid fracture classifications and fixation.…”

Proximal ulna fractures are common injuries in the upper extremity. The severity of injury ranges from isolated olecranon fractures to complex elbow fracture dislocations. Relevant anatomic features of the proximal ulna for fracture management are presented in the first part of this article. Furthermore, standard and recent techniques of surgical treatment are described in detail for olecranon and Monteggia fractures as well as for fractures of the coronoid process. Functional outcome and complications of fracture treatment are discussed.
