ABSTRACT
[Objective]To investigate the causes and treatment methods of postoperative complications of femoral fractures treated with interlocking intramedullary nails.[Method]A total of 243 cases of femoral fractures from Jan 1999 to Dec 2004 were treated with interlocking intramedullary nails.There were 14 cases having complications,delayed union in 1,nonunion in 3,nailing failure in 6(locking scerw loosen in 4,locking scerw folding in 1,locking scerw breakage in 2),nail breakage in 1,re-fracture in 1 and knee ankylosis in 1.Two cases with delayed union to convert the fixation from statictody namicin time;3 cases with nonunion were treated with bone grafting.Breakage nail and re-fractuer cases were treated with enlarging intramedullary tunels,exchanging nails and bone grafting.One of locking scerw loosen were treated with exchanging nails and bone grafting.Knee ankylosis were treated with quadriceps plasty.[Result]Through treatment,the delayed union and the nonunion were all healed and got recovery of knee function.[Conclusion]Though it has certain complications,the interlocking intramedullary nails used for femoral fractures have more advantages than other internal fixations.It needs to take valid measures to reach a satisfying result when complication appears.
ABSTRACT
Objective To study surgical treatment of complex fractures of the tibial plateau. Methods Forty eight cases of complex fractures of the tibial plateau were treated with internal fixation from January 1997 to December 2001. According to Schatzker classification, 12 cases were type Ⅲ, 9 cases type Ⅳ, 14 cases type Ⅴand 13 cases type Ⅵ. They were treated with open reduction and internal fixation with buttress plates and allograft implantation for defective fractures. Results Forty six cases of the forty eight were followed up for 1 to 4 years. The excellent and good rate was 77%. Conclusion The complex fractures of the tibia plateau should be treated surgically, and the operation procedures should be varied according to the fracture types.
