Impinging exostoses of the proximal radius: a report of two cases with distinct clinical features.

Owing to the rotatory motion of proximal radius and the closely apposed anatomic structures, cortically based osseous lesions at the level of the proximal forearm may produce symptomatic impingement. While osseous impingement onto the adjacent proximal ulna may result in limited forearm rotation, impingement on the surrounding soft-tissue structures may produce symptoms as well. Here, we describe two cases of symptomatic proximal radius exostosis, each of which produced distinct clinical symptoms.

Fix it or discard it? A retrospective analysis of functional outcomes after surgically treated patella fractures comparing ORIF with partial patellectomy.

Objectives: The goal of this study was to compare functional outcomes of patients with patella fractures treated with open reduction and internal fixation (ORIF) with those treated with partial patellectomy (PP).

Design: Retrospective cohort study.

Setting: Urban Level I Trauma Center.

Murine patellar tendon biomechanical properties and regional strain patterns during natural tendon-to-bone healing after acute injury.

Tendon-to-bone healing following acute injury is generally poor and often fails to restore normal tendon biomechanical properties. In recent years, the murine patellar tendon (PT) has become an important model system for studying tendon healing and repair due to its genetic tractability and accessible location within the knee. However, the mechanical properties of native murine PT, specifically the regional differences in tissue strains during loading, and the biomechanical outcomes of natural PT-to-bone healing have not been well characterized.

Management of extra-articular fractures of the distal tibia: intramedullary nailing versus plate fixation.

Intramedullary nailing and plate fixation represent two viable approaches to internal fixation of extra-articular fractures of the distal tibia. Although both techniques have demonstrated success in maintaining reduction and promoting stable union, they possess distinct advantages and disadvantages that require careful consideration during surgical planning. Differences in soft-tissue health and construct stability must be considered when choosing between intramedullary nailing and plating of the distal tibia.
