The goal of this study is to determine the efficacy of the surgical treatment of lateral Hoffa fracture with a locking plate and cannulated or lag screws through the lateral approach.
A total of 12 isolated lateral Hoffa fractures were identified during the study period (February 2005 to February 2010). All fractures were treated by open reduction through the lateral approach. Internal fixation was performed with a contoured locking plate and cannulated or lag screws introduced from the non-weight-bearing area of the cartilage surface of the lateral femoral condyle. Radiological and functional outcome analysis was performed using Knee Society scores.
Bony union of Hoffa fracture was achieved in all patients. The articular surface of lateral femoral condyle was anatomically reduced. There was no loss of reduction and fixation. Functional outcome of knee measurements showed a continuous significant improvement over the follow-up period.
Fixation with a locking plate and cannulated or lag screws for lateral Hoffa fracture seemed to be effective and reliable. The lateral approach had advantages for reduction and fixation of lateral Hoffa fracture during operation.
本研究的目的是确定采用锁定钢板及空心钉或拉力螺钉经外侧入路手术治疗外侧Hoffa骨折的疗效。
在研究期间（2005年2月至2010年2月）共识别出12例单纯外侧Hoffa骨折。所有骨折均采用经外侧入路切开复位治疗。使用塑形锁定钢板及从股骨外侧髁软骨面非负重区置入的空心钉或拉力螺钉进行内固定。采用膝关节协会评分进行放射学和功能结果分析。
所有患者的Hoffa骨折均实现了骨愈合。股骨外侧髁的关节面解剖复位。复位及固定无丢失。膝关节测量的功能结果在随访期间持续显著改善。
采用锁定钢板及空心钉或拉力螺钉固定外侧Hoffa骨折似乎有效且可靠。外侧入路在手术中对外侧Hoffa骨折的复位及固定具有优势。
