The proximal ulna, particularly the course of the posterior border, has a complex three-dimensional (3D) morphology which has been highlighted recently due to its clinical relevance in relation to surgical treatments. 3D computed tomography (CT) reconstruction and computer-aided design (CAD) based software can help to visualize the complex anatomy and thus aid the investigation of the more detailed morphology of the proximal ulna. ⋯ In conclusion, variations in the proximal ulna have to be considered when anatomically contoured dorsal plates are applied. Knowledge of the 3D morphologic anatomy of the proximal ulna would provide important information on fracture reductions, and the design of a precontoured dorsal plate or a prosthetic ulnar stem.

The aim of this dissection study was to describe the anatomical insertions of the medial patello-femoral ligament (MPFL), and to assess its relationship with surrounding structures to improve its surgical reconstruction. ⋯ The adductor tubercle appeared to be a better landmark than the MFE for the femoral tunnel positioning during surgical reconstructions of the MPFL because it was easier to identify and its relationship with the femoral insertion of the MPFL was constant (10 mm below).

Given the severity and incidence of injury to the common fibular (peroneal) nerve (CFN), there is a need to further clarify its anatomical location and branching patterns. This project attempts to consolidate current anatomical understanding of this nerve and provide physicians with reproducible measurements regarding the CFN and its branches. ⋯ These findings allow physicians to better assess a patient's individual CFN anatomy based on correlations with measureable physical traits and will contribute to anatomic education and successful completion of various surgical, anesthetic, and physical therapy procedures.
