Case ReportsTibial hypo-/aplasia with preaxial syn- and polydactyly.
Tibial hypo-/aplasia with preaxial syn- and polydactyly is a rare autosomal dominant condition. Fewer than 20 cases have so far been described. One is presented here.

Reaming versus non-reaming in medullary nailing: interference with cortical circulation of the canine tibia.
Medullary nails have only been used with reluctance in the treatment of open fractures since reaming interferes with the cortical circulation. The technique of interlocking offers the interesting possibility of inserting a relatively stiff nail which does not necessarily require reaming. ⋯ Nail insertion without reaming provided clear advantages for the bone's blood supply, while reaming disturbed perfusion in two-thirds of the cortical area and regionally extended through the entire thickness of the cortex. The disturbance without reaming was limited to the inner layer of the cortex and involved only one-third of the cortical cross-section.

Case ReportsModification of the Wagner lengthener to permit dynamic axial loading.
The Wagner lengthener is mechanically excellent, but it lacks a function allowing dynamic axial loading (dynamization), which stimulates bone consolidation at the lengthened section. The authors devised a simple metal insert with which they modified the Wagner lengthener to permit dynamization. The modified appliance was successfully used in two patients.

Ultrasonographic detection of foreign bodies in soft tissue. A human cadaver study.
The usefulness of ultrasound in the detection of foreign bodies was examined in a blind study in human cadavers using glass, plastic and wood as foreign bodies. Of 65 foreign bodies placed in 102 cicatrices, 58 were found using a 5 MHz transducer. The sensitivity was 89% and the specificity 93% making ultrasound a useful clinical tool for this purpose.

Comparative StudyDisplaced distal radius fractures. A comparative study of early results following external fixation, functional bracing in supination, or dorsal plaster immobilization.
A comparison of the radiographical and functional results after displaced distal radius fractures in 41 patients treated by external fixation (EF), 36 patients treated by functional bracing in supination (FUSU), and 49 patients treated by dorsal plaster immobilization (DPI) was performed. The rate of initial complications after EF was 53%, compared with 22% after FUSU and 14% after DPI. The radiographical result after EF was significantly better than after nonoperative treatment, but the functional result after 3 and 6 months demonstrated no significant difference between the three series. Consequently, EF and FUSU do not restore wrist function faster than conventional plaster treatment (DPI), but EF improves the radiographical result, though the rate of complications is higher.
