ABSTRACT

Background: With the growing interest in long bone distraction several types of distractors have been introduced; all have the same principle of an outer structure which acts like a scaffold and the distracting mechanism is a separate device which is mounted on this outer structure.

Objectives: We have used a simple and very light weight external fixator we designed and discuss the results of distraction and advantages of this device .

Materials and methods: We applied our distractor to treat 14 men and four women, with a mean age of 39 years. There were three thumbs and 23 fingers; 26 digits (18 patients) lengthened by distraction callotasis and second stage bone grafting evaluated accordingly.

Results: All patients but one were satisfied with the results and a stable pinch and grip was obtained. After lengthening, all patients maintained sensation of the finger pulp, as assessed by the Semes - Weinstein test.

Conclusions: The superiority of this device for manoplasty lies in its simplicity of construction in addition to being, lightweight and also eases of application.

Mentions: The objective of this study was to test the effectiveness of the distractor we have designed; it is radically different from the current types because the distracting device is the outer structure (scaffold) or the "rods" themselves; the rods in currently available distractors act as only scafold and the distracting device is mounted over these rods. In our device the rods are long screws with an "eye" at one end and the sliding sleeve with two "eyes" for the pins which will distract the bone and these sleeves slide over the rods by tightening the bolts behind the sleeve on the rods (Figures 1, 2, 3).
