The effect of malunion on functional outcome after plate fixation of fractures of both bones of the forearm in adults.

Fifty-five adults who had a fracture of both bones of the forearm were managed with plating and were followed for a mean of six years (range, one year to sixteen years and two months) with functional and radiographic assessment. Malunion was quantified by measurement of the amount and location of the maximum radial bow in relation to the contralateral, normal forearm. Fifty-four of the radial and fifty-four of the ulnar fractures united. Eighty-four per cent of the patients had an excellent, good, or acceptable functional result, according to the criteria of Grace and Eversmann. Bone-grafting did not affect the rate of union. Restoration of the normal radial bow was related to the functional outcome. A good functional result (more than 80 per cent of normal rotation of the forearm) was associated with restoration of the normal amount and location of the radial bow (p less than 0.05 and p less than 0.005). Similarly, the recovery of grip strength was associated with restoration of the location of the radial bow toward normal (p less than 0.005).

Biological fixation of subtrochanteric fractures by external fixation.

Fifty-one subtrochanteric fractures have been stabilized by external fixation over the last 9 years. Union occurred in all types of fractures, usually within 6 months. Soft tissue interposition led to non-union in three patients. Refracture in one patient and significant limb-length discrepancy in two patients was seen. The technique is versatile, easily reproducible and 'biological'. Protected weight-bearing is not necessary after removal.

Conversion from temporary external fixation to definitive fixation: shaft fractures.

Temporary external fixation is the most common method of initial stabilization of diaphyseal fractures in forward surgical hospitals. Once the patient arrives at a stable environment, usually the United States, the fracture is managed with intramedullary nailing, small-pin external fixation, or a modified external fixator. Future research should be directed toward improving methods of care. It is not precisely known when is the best time to convert to definitive fixation without increasing the risk of infection. The risk factors leading to infection and nonunion are not well-established, making that determination even more difficult. Clinical studies of a suitable size should provide insight into these problems. Although temporary external fixation is commonly used, an optimal construct has not been determined. Data from studies of in vivo fracture-site motion after application of the temporary external fixator should be compared with biomechanical testing of similar constructs. These data could be used to recommend optimal temporary external fixation constructs of tibia, femur, and humerus fractures using currently available devices as well as to provide groundwork for the next generation of fixators.

Effects of fixation stiffness on fracture healing. External fixation of tibial osteotomy in the rabbit.

In rabbit tibial osteotomies, the effects on bone healing of three different degrees of stiffness of external fixation were investigated. Redislocation occurred in one third of the osteotomies with the least rigid fixation, and the amount of external callus was greater in this group. At 6 weeks there were no significant differences between the groups regarding bending strength and stiffness of the bones.
