Biomechanical analysis of dorsal plate fixation in proximal phalangeal fractures.

The biomechanical properties of three minifragment plate and screw systems were compared to determine whether plate systems primarily designed for maxillofacial reconstruction are biomechanically sound for use in proximal phalangeal fracture fixation. A middiaphyseal transverse osteotomy was created in each of 30 fresh-frozen human proximal phalanges to simulate an unstable fracture. Each osteotomy was then fixed with four 2.0ml screws through one of three different four-hole minifragment plates in a middorsal position. Plating systems tested included a vitallium plate with self-tapping screws (Luhr), a stainless steel plate with tapped screws (Synthes), and a titanium plate with tapped screws (Synthes). Testing was performed to failure in an apex volar three-point bending mode. The titanium-plated phalanges were the stiffest construct and required the greatest load and total energy absorbed to failure. However, only the load to failure for titanium versus stainless steel was significantly different. Therefore, there is no biomechanical disadvantage to using the titanium or vitallium plate and screw systems in the setting of unstable proximal phalangeal fractures.

Duration of fracture healing after early versus delayed internal fixation of fractures of the femoral shaft.

The effect of delayed internal fixation in closed uncomplicated fractures of the femoral shaft was studied by comparing 40 patients from a hospital where this fracture was principally treated within 24 hours of the injury, with 46 patients from another hospital where this type of fracture was principally treated after a mean period of 13 days in skeletal traction. The two groups of patients were similar with regard to age, level of fracture, type of fracture and incidence of comminution. All fractures were treated by stable internal fixation. In the group treated by early operation considerably longer AO plates were used. Although delayed fixation resulted in more callus and although secondary bone healing was more frequent than in the group with early internal fixation, no difference in the rate of union of the fractures could be demonstrated.

Internal fixation of distal fibula fractures: a case presentation demonstrating a unique technique for a severely comminuted fibula.

The laterally comminuted fracture-dislocation of the ankle can be associated with devastating consequences. Previously described surgical as well as nonsurgical-treatment results have been disappointing. Accurate anatomical reduction and rigid fracture stabilization of a comminuted fibula can be extremely difficult. This manuscript presents some of the more common methods of comminuted fibular fracture fixation described in the literature. A case report demonstrates successful anatomical stabilization of a comminuted fibula, utilizing a method for internal fibular fixation which has been previously employed, but has not been advocated, in the literature. Clinical and radiographic results at 12 and 20 months post-injury are promising.
