Pyomyositis is rarely seen in temperate climates. Typically, it presents with the formation of an abscess requiring surgical drainage and it has been reported as a differential diagnosis for septic arthritis of the hip. We describe the occurrence of pyomyositis of the iliacus muscle in a ten-year-old girl which was diagnosed by MRI and blood culture. Formation of an abscess did not occur despite marked focal inflammation and swelling of the muscle. Conservative treatment with antibiotics alone led to complete clinical and radiological resolution of the infection. We could find no previous description of pyomyositis in a child in the British orthopaedic literature. Orthopaedic surgeons, particularly those with a paediatric interest, should be aware of this condition and its presentation, diagnosis and treatment.

Angioplasty is useful in the treatment of long-segment femoropopliteal atherosclerotic disease.

Pseudoangiomatous stromal hyperplasia (PASH) is a rare benign proliferating breast condition. It was first reported in 1986 when Vuitch, Rosen, and Erlandson described nine cases of benign well-circumscribed, breast masses that simulated vascular lesions consisting of mammary stromal proliferations (Vuitch et al. (1986)). Since then there have been few reported cases of PASH in the literature (Taira et al. (2005)). We describe a large PASH, mimicking inflammatory carcinoma in a young lady that was excised with excellent cosmetic results.

Posterior dislocation of the sternoclavicular joint is an uncommon injury. Since 1824, when Sir Astley Cooper described the injury, little more than 100 cases have been described, and the majority of these have been in the last decade, identified by computed tomography. The significant morbidity and mortality associated with this injury is based upon serious damage to important anatomical structures found in the vicinity of the joint. We present a case report, describe the relevant clinical anatomy of this region, and review associated complications.
