Comparative Study
Resection of the lateral end of the clavicle. A 3 to 30-year follow-up.
Fifty patients, operated on with resection of the clavicle, were evaluated postoperatively after an average of 9 years. There was no significant difference between the traumatic and non-traumatic group. ⋯ Radiographic examination of 30 shoulders showed newly formed bone at the resected clavicle in one third and radio-opaque deposits in the resection gap in another third. These findings were consistent with good outcome.

Rereduction was carried out in 5% of all treated Colles' fractures and they were externally fixated with a one-bar Hoffmann apparatus. The results of 57 of the first 69 patients treated with a follow-up time of at least 1 year are presented. Using Frykman's criteria, 18 patients were judged as "excellent", 25 as "good" and 14 patients were judged as "unsatisfactory". ⋯ Among the first patients, five cases of pin-loosening were seen, but there were no adverse effects in the final result. There were no pin-tract infections. The results justify using the method as a routine when a redislocated Colles' fracture is rereduced.

Comparative Study
Size, site and clinical incidence of lipoma. Factors in the differential diagnosis of lipoma and sarcoma.
All 428 patients who had a non-visceral lipoma histopathologically diagnosed during 1 year in a defined population (0.74 million inhabitants) were analysed retrospectively as regards the age, duration of symptoms, size, site (location and depth) and multiplicity of the lipomas. Solitary subcutaneous lipomas were uncommon in the hand, thigh, lower leg and foot, and four-fifths of them (264/338) were smaller than 5 cm. Multiple subcutaneous lipomas were found in 61 patients, most of them young males. ⋯ Based on these data, the annual clinical incidence of lipoma (number of patients consulting a doctor for a lipoma, even if not histologically verified) was estimated to be 1/1000. When the data for solitary lipomas were compared to those for soft-tissue sarcoma, it was found that patient age and duration of symptoms were of minor value in the clinical differential diagnosis. However, if a tumour were (a) larger than 5 cm, irrespective of depth and location, (b) located in the thigh, irrespective of depth and size, or (c) deep, irrespective of location and size, it was more likely to be a sarcoma.(ABSTRACT TRUNCATED AT 250 WORDS)
