A Rare Case of Patella Fracture in Osteopetrosis: A Case Report.

Case: Fractures in patients with osteopetrosis pose unique technical challenges to the orthopaedic surgeon. We present a case of a 43-year-old man with osteopetrosis who underwent tension band wiring of a patella fracture. The intraoperative appearance of osteopetrotic bone, technical difficulties in passing wires through dense bone, and how this was overcome are presented.

The Anatomic Pattern of Injuries in Acute Inversion Ankle Sprains: A Magnetic Resonance Imaging Study.

Background: There are little data on the incidence and patterns of injuries seen on magnetic resonance imaging (MRI) in acute inversion ankle sprains. This study may help in the understanding of the pathomechanics, natural history, and outcomes of this common injury.

Study Design: Case series; Level of evidence, 4.

An unusual case of "locking" of the knee four years post fixation of an open supracondylar femur fracture.

Unlabelled: The introduction of locking plate devices have increased the number of viable options for fracture fixation. An understanding of the indications and contraindications and technique limitations are important to minimise associated adverse events. We report the case of a patient who presented with a single broken screw head four years following fixation of a supracondylar femur fracture, resulting in symptoms of migratory knee pain and locking.

A colonic submucosal lipoma presenting with recurrent intestinal obstruction attacks.

Colonic submucosal lipomas are rare benign tumours of the colon, which may be discovered incidentally at colonoscopy, through imaging such as CT or at autopsy. These tumours can cause complications such as bleeding, intussusception and bowel obstruction. We describe the case of a patient in whom a small submucosal lipoma was identified at the time of colonoscopy and who did not receive follow-up treatment.

A systematic review of brain metabolite changes, measured with 1H magnetic resonance spectroscopy, in healthy aging.

Background: (1)H MR spectroscopy (MRS) can identify metabolite abnormalities in age-related, neurological diseases. However, there is little information on how metabolites change with healthy aging.

Methods: We systematically reviewed the literature on MRS, from 1980 to 2006, for studies where healthy young subjects (<60 years) were compared to healthy older subjects (>60 years).
