Modified Phemister grafting in potentially infected non-union of tibial shaft fractures.

Modified Phemister bone grafting consisting of the raising of an osteoperiosteal flap, bone petalling and a cancellous onlay graft for non-union of tibial shaft fractures was tried in 43 cases. Thirty-eight out of 43 fractures united after one bone grafting procedure, giving a success rate of 88%. The procedure can even be used in the presence of low-grade, active infection. This method of bone grafting is simple and has no significant complications. Knee motion recovers well but ankle and toe stiffness do not improve appreciably from the preoperative status. We recommend that Phemister grafting be performed early.

Microstructural organization of carbon induced neotendon.

Experiments have been conducted in guinea pigs to replace the calcaneal tendon with carbon fibers. The new tendon formed has been studied macroscopically, histologically and by scanning electron microscopy, and shows a close resemblance to the normal tendinous structure but is adherent to the surrounding tissues. It is suggested that the surface characteristics of carbon fibers play an important role in that these attract and allow fibrinous exudate to spread on their surface, into which fibroblasts grow. This, together with the large surface area available, is probably responsible for the orderly longitudinal arrangement of collagen fibers parallel to the carbon fiber implant.
