In one group of rats, the medullary cavity was reamed and bone cement was injected. In a control group, only reaming was performed. ⋯ No differences were found between the two groups. It is concluded that acrylic bone cement in the medullary cavity does not impair the healing of non-immobilized fractures in young rats.

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
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.

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)

In a retrospective study in children aged 0-18 years, 457 ankle fractures in children were classified traumatologically according to Gerner-Smidt or Lauge-Hansen. Anatomically, ankle fractures with open growth plates were classified according to the Salter-Harris classification. Pronation injuries constituted 18% of the ankle injuries and showed different fracture patterns. ⋯ Pronation-dorsal flexion showed a physeal-metaphyseal fracture in four cases with an anteriorly situated metaphyseal fragment (Stages I-II); one case also had a metaphyseal fracture of the distal fibula (Stage III). Pronation-eversion injuries showed frequently displacement and were more commonly treated by reduction than pronation-abduction and supination injuries including supination-eversion injuries of intra-articular type. However, complete reduction of pronation-eversion injuries with closed methods often proved difficult.
