RESUMO
Twenty-eight patients with tibial plateau fractures treated by closed reduction using forceful traction and percutaneous stabilization with pins or screws were reviewed. For six bicondylar fractures, transfixion pins with an external fixation device were used. In six cases, an arthroscopic exam was also done. For 21 patients, external support was used postoperatively. Twenty-one patients were followed an average of 26 months. All fractures healed. Functional ratings were: 14 excellent, 6 good, and 1 poor. Radiographic ratings were: 11 excellent, 9 good, and 1 fair. For fractures with large fragments without excessive comminution or severe central depression, this technique yields good results with minimal surgical morbidity.

Computerized tomography is an established modality for use in the evaluation of acetabular fractures. As open reduction and internal fixation of acetabular fractures becomes more common, the need for an accurate understanding of the fracture anatomy is critical. An anatomic study of the innominate bone is reported and the relevant standard radiographic landmarks as seen with computerized tomography are illustrated.

Neonatal pigs were used to develop a surgical biopsy procedure to remove bone tissue from the ilium of small animals, with potential application for infants and small children. While the neonatal pig was under general anaesthesia, a scalpel was used to make a punch incision down to the ilium. Then a Craig Biopsy Trephine was used to remove a core sample of the bone. The samples ranged from 5 to 15 mm in length and 2 to 3 mm in diameter, with an average dry weight of 34.4 mg. The samples were adequate for mineral (calcium and zinc) analysis in our laboratory and may be equally suitable for histological or biochemical analyses. Surgical trauma was minimal, which permitted each pig to be biopsied every 7 days for 5 weeks without adverse consequences.
