Abstract:
We present a rare, previously undescribed case of a superior patella sleeve fracture in a skeletally immature adolescent male, just 1 month following surgery for an ipsilateral traumatic inferior pole patella fracture. This was initially missed resulting in a delay to surgery. We recommend a high index of suspicion is key in these patients who re-present following subsequent trauma and alternative X-ray views such as a flexed lateral can be extremely beneficial.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
