Marjolin's squamous cell carcinoma of the hallux following recurrent ingrown toenail infections.

Marjolin's squamous cell carcinoma (SCC) affecting the toe is rare. Due to resemblance with benign conditions it can often result in misdiagnosis. We report a case of Marjolin's SCC affecting the proximal hallux in a patient with recurrent ingrown toenail infections.

Protrusio acetabuli: a rare cause of pulmonary embolus.

Protrusio acetabuli is an uncommon complication of total hip arthroplasty, which results in intrapelvic implant migration after erosion of medial acetabular wall. We present a case of severe prosthetic migration with the formation of haematoma and impingement on iliac vessels leading to thrombosis and subsequent pulmonary embolus. This is the first reported case of protrusio acetabuli as a cause of pulmonary embolus.

Bilateral distal tibial stress fractures in a healthy field-hockey goalkeeper.

Stress fractures occurring within the lower limbs are relatively common in athletes and military personnel. The specific bones affected are often predictable when the patient's activities are considered. We present an unusual case of bilateral distal tibial stress fractures sustained while playing as a goalkeeper in field hockey, in an otherwise healthy 46-year-old woman.

Implant failure caused by non-union of bisphosphonate-associated subtrochanteric femur fracture.

Bisphosphonate use has been identified as a contributory factor in atypical subtrochanteric fracture of the femur. These fractures are commonly treated with an intramedullary device. We present a case of implant failure of an intrameduallary device caused by non-union of an atypical subtrochanteric fracture.

Transstyloid, transscaphoid, transcapitate fracture: a variant of scaphocapitate fractures.

Transstyloid, transscaphoid, transcapitate fractures are uncommon. We report the case of a 28-year-old man who sustained this fracture following direct trauma. The patient was successfully treated by open reduction internal fixation of the scaphoid and proximal capitate fragment, with a good clinical outcome at 1-year follow-up.

Metastatic transitional cell carcinoma of the tibia radiologically mimicking osteosarcoma.

We report a case of a 73-year-old lady with transitional cell carcinoma and no evidence of metastatic disease presenting with gradual weight loss, pretibial swelling and painful weightbearing. Investigations revealed a lesion of the right tibial diaphysis. The radiological and clinical appearance was that of primary osteosarcoma.

Snowboard, wakeboard, dashboard? Isolated fracture of the lateral process of the talus in a high-speed road traffic accident.

We present a 23-year-old man who sustained an isolated fracture of the lateral process of the talus (LPT) in a head-on vehicle collision at a combined speed of 200 km/h. The driver of the other vehicle sustained fatal injuries at the scene. The LPT was openly reduced and fixed with successful outcome at 3 months.

Clavicle fractures: a comparison of five classification systems and their relationship to treatment outcomes.

We compared five classification systems for clavicle fractures. The aim of this study was to evaluate the prognostic value of each system. Over a two-year period we reviewed all new radiographs of the shoulder region and identified 487 clavicle fractures.
