ABSTRACT
Avascular necrosis of the lunate is a process that is not well understood. The cause is uncertain, but a common theory persists that it is caused by disruption of the vascular supply to the lunate. This article discusses an approach to assessment that respects the articular cartilage and places at the front of the decision-making process the pathoanatomic components of the articular cartilage. It primarily respects the articular cartilage in the patient with avascular necrosis. This approach was developed for avascular necrosis of the lunate, but in principle applies to other joints with avascular necrosis as well.

Biceps or triceps ruptures are rare but can cause a significant disability. Surgical repair has become the preferred method of treatment for the complete rupture, but the decision when to treat partial tears is less clear. Reconstruction of the tendon is the preferred method when patients have a delayed presentation.

Neurovascular complications have been reported from both plate osteosynthesis and intramedullary fixation of midshaft clavicle fractures. We wish to report a case of limb threatening ischemia from screw penetration of the axillary artery after plate osteosynthesis for a clavicle nonunion. A literature review of vascular trauma from midshaft clavicle fractures is presented.
