The surface cells form more cartilaginous layers, so enlarging the body over time. (2018) Journal of orthopaedic trauma. The AO classification of distal femoral fracturesis one of the commonly used fracture classification systems in orthopedics. Specifically it is when the ballshaped head of the femur (femoral head) separates from its cupshaped socket in the hip bone, known as the acetabulum.The joint of the femur and pelvis is very stable, secured by both bony and soft-tissue constraints.With that, dislocation would The use of the term "loose" is frowned upon by some authors because the fragments do not necessarily move around in the joint ref - the term intra-articular body or fragment is a safer alternative.

Patients may be entirely asymptomatic or complain of pain, clicking and locking, depending on the location and mobility of the fragment as well as any associated secondary degenerative disease, and symptoms from the underlying cause. A Shepherd fracture refers to a fracture of the lateral tubercle of the posterior process. Classification. An elongated lateral tubercle of the posterior process of the talus is referred to as a Stieda process, so occasionally these fractures are described as Stieda process fractures.. A Cedell fracture is a fracture of the medial tubercle of the posterior The AO classification divides the distal femoral fracturesinto three groups, A, B and C with complexity and severity increasing 1. The distal femur system's prefix is 33, indicating it is the femur (3) and the distal portion of the femur (3). Deeper cells receive less nutrition resulting in cell death and calcification 2.
