Abstract:
Objective To observe the clinical effects of tibial locking multidirectional interlocking intramedullary nail (TLMIIN) for tibial plateau fractures. Methods 38 cases with closed tibial plateau fractures treated by TLMIIN from October 2008 to May 2012 were retrospectively analyzed. There were 22 males and 16 females, with an average age of 48.7 years (range, 28-67 years). There were 24 fractures on the left side while the other 14 factures were on the right side, which were all fresh frac?tures. According to AO/OTA classification of tibial plateau fractures, there were 4 cases of B1, 1 case of B2, 14 cases of B3, 8 cas?es of C1, 5 cases of C2 and 6 cases of C3. Close reduction were performed on 4 cases (10.5%of all cases). Open reduction were performed on the other 34 cases. The limited incision was decided by the distribution of the fragments and fracture line. Hohl?Luck evaluation system was applied for the follow?up. Results The mean follow?up period was 18.1 months (range, 11-23 months). All fractures were healed at an average period of 87.4 days (range, 48-131 days). The average time from operation to full weight?bearing was 108.9 days (range, 80-128 days). Hohl?Luck evaluation system was used in the final follow?up. The excellent and good rate of functional score was 94.7%(36/38), including 28 cases excellent, 8 cases good and 2 cases fair from functional as?pect. The excellent and good rate of radiological score was 84.2%(32/38), including 23 cases excellent, 9 cases good and 6 cases fair from radiological aspect. No complications such as infection, breakage and loosening of the screw, malunion, nonunion oc?curred at the time of the latest follow?up. 6 cases with serious swelling of the knee joint and the soft tissue of crus were cured by an?ticoagulation, dehydration and physiotherapy treatments after operation. The 2 cases with a little exudates and incrustation was bacterial cultured negative and healed after 16 days and 18 days on the incision. 1 case had lost of reduction due to weight?bearing 1 week after operation, who had 25 degree of varus deformity, which was left dispose, and the bone healing and joint function were unaffected. Conclusion The intramedullary support, restrictive and non?restrictive multidirectional tridimensional fixation of TLMIIN technology had satisfactory effects in treating plateau fractures. It can supply a new therapeutic method, with little dam?age of soft tissues when taking out the internal fixation and reduce some postoperative complications.
