These range from subtle ligamentous sprains, often seen in athletes, to fracture dislocations seen in high-energy injuries. Accurate and early diagnosis is important to optimise treatment and minimise long-term disability, but unfortunately, this is a frequently missed injury. Undisplaced injuries have excellent outcomes with non-operative treatment. Displaced injuries have worse outcomes and require anatomical reduction and internal fixation for the best outcome. Although evidence to date supports the use of screw fixation, plate fixation may avoid further articular joint damage and may have benefits. Recent evidence supports the use of limited arthrodesis in more complex injuries.

We performed histological examination of the femoral heads and cancellous bone biopsies from four regions of the proximal femur in patients undergoing total hip arthroplasty. A control group consisted of 19 patients with osteoarthritis. All histological specimens were examined in a blinded fashion.

Some experts have advocated augmentation with the flexor hallucis longus (FHL) tendon in patients over age 50 and those with more severe tendon disease. We hypothesized that FHL augmentation would be associated with superior clinical outcome scores and greater ankle plantar flexion strength compared with Achilles debridement alone. Consecutive patients older than 50 years who had failed nonoperative treatment for chronic insertional Achilles tendinopathy were randomly assigned to Achilles decompression and debridement alone (control group) or Achilles decompression and debridement augmented with FHL transfer (FHL group). Outcome measures included American Orthopaedic Foot & Ankle Society (AOFAS) ankle/hindfoot score, visual analog scale (VAS) for pain, ankle and hallux plantar flexion strength, and a patient satisfaction survey. A total of 39 enrolled patients had a minimum 1-year follow...
