Locked intramedullary flexible osteosynthesis. A mechanical and clinical study of a new pin fixation device.

We report the use of a new method of locked intramedullary flexible osteosynthesis (LIFO) in the treatment of 118 unstable fractures of the femur and tibia. The implant utilises a set of flexible pins with a separate locking device for their proximal ends. The LIFO system proved capable of stabilising unstable fractures, and most of the complications occurred during the early testing. At follow-up, 19 of 21 femoral fractures had healed; one become infected and one showed defective callus. Of the 78 tibial shaft fractures, five failed to consolidate and five had inadequate callus. Reaming of the tibial medullary canal was never necessary. Of 28 open fractures only one became infected. The system was most difficult to use in comminuted distal fractures of the tibia, with five failures of healing in 19 cases; these cases require considerable technical proficiency. The flexibility of the system appears to promote earlier consolidation of open fractures, and normal consolidation times for fractures with interfragmentary gaps of up to 10 to 12 mm. A comparative study of callus density in tibial fractures showed a mean improvement of 50 days in cases treated by the LIFO system compared with similar cases treated by rigid nailing.

[A computer-directed measuring device to analyse pathological gaits].

The clinical observation of the walk is still the only current way to define the limp, but is obviously quite a rough valuation. Taking advantage of previous studies and recent improvements in electronics, the authors have built a measuring unit-including a computer-designed for daily clinical use. This unit provides in a few minutes the variations of the ground reaction to the human body during the walk, and the displacement of the point to which this reaction is applied. Seven to ten patients per hour may be examined, including previous analysis of the results by the computer.
