Sleeve fracture of the patella in a child
1Faculty of Medicine and Health Sciences, Universiti Malaysia Sarawak, Kuching, Sarawak.
Abstract:
Sleeve fracture of the inferior pole of the patella is a rare and distinctive fracture in children with few published reports. These fractures are frequently misdiagnosed and neglected. We highlight a case of a neglected and misdiagnosed sleeve fracture of the patella in an eleven-year-old boy. This was initially diagnosed as an avulsion fracture of the tibial tubercle. A good outcome was achieved after open reduction and internal fixation.

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 procedure...
