["Biorigid" interlocking after unreamed intramedullary nailing of tibial shaft fractures].
Between April 1996 and December 1999, 76 tibial shaft fractures were treated at the Department of Trauma Surgery of the Justus-Liebig-University in Giessen, Germany and the Department of Orthopedic Surgery of the University of Louisville, USA with a newly developed, unreamed, solid, small diameter tibial nail interlocked "biorigidly" with screws in grooves of the nail. 69 Patients were reviewed with a minimal follow-up period of 16 months. In 65 patients, the fractures united without exchange nailing, although four of these fractures showed a delay of healing. In further four cases, non-union occurred, one of which was associated with the only break of a nail located at a distal interlocking groove of the nail. In one patient, a late medullary infection so far has not recurred following treatment. In 358 implanted interlocking screws, no implant failure was observed. First clinical experience suggests that, especially due to the low rate of material fatigue, the biorigid nail is an alternative to other implants for unreamed intramedullary nailing of the tibia.
