Adaptation of Ilizarov ring fixator to the economic situation of developing countries.
Especially in countries with low per capita income, poor patients with open fractures and non-unions are unable to purchase modern, commercially produced surgical implants. To alleviate this situation, we initiated the production of a locally made ring fixator. The rings were cut from tubes cast from scrap aluminium. ⋯ The subacute infections in 11 (27.5%) patients were not due to the fixator itself but to low standards of hygiene and the delay of treatment in the prehospital phase. Reusing the fixator at least three times reduces the cost for the individual patient to US$ 13.60. A locally made fixator is cost-effective and can be recommended for surgical treatment under similar economic situations.

Between September 1980 and May 1982, 112 primary unilateral total hip arthroplasties with the original cemented M. E. Müller Straight stem (manufactured from Protasul-10, a CoCrNiMo alloy) were inserted in 109 consecutive patients, all combined with non-cemented, non-coated polyethylene RM cups. ⋯ Subsidence of over 2 mm was found in 20 hips (41%), 6 of them within the cement mantle. There was no correlation between subsidence and pain. The cause for the poor results is primarily the high rate of aseptic loosening of the non-coated, non-cemented all-polyethylene RM cups, with a loosening rate of 63% and a revision rate of 25% after 15 years.

Case ReportsPrimary intramuscular hydatidosis of supraspinatus muscle.
Hydatid disease of the muscle is very rare and represents approximately 3% of all patients with hydatidosis. Since the infection closely resembles a soft-tissue tumor on clinical examination, the preoperative radiologic diagnosis is very important to avoid biopsy. We report an unusual case of primary intramuscular hydatidosis with its magnetic resonance imaging appearance, clinical and pathological findings.

Case ReportsOsteoid osteoma of olecranon process of ulna in subchondral location.
We present a case of a 15-year-old girl with osteoid osteoma in an unusual subchondral localization of the olecranon. Unspecific complaints and minimal X-ray findings at the onset of the disease led to an incorrect diagnosis and more than 2 years of inefficient treatment.

Clinical TrialTailor's bunion: results of a scarf osteotomy for the correction of an increased intermetatarsal IV/V angle. A report on ten cases with a 1-year follow-up.
The aim of this study was to analyze clinical and radiological results of scarf osteotomy for the correction of an increased intermetatarsal IV/V angle in patients with symptomatic tailors bunion. ⋯ The scarf osteotomy is an adequate surgical procedure for the correction of an increased IMA in patients with symptomatic tailor's bunion.
