改良股前外侧入路治疗股骨远端C型骨折的应用解剖
Applied anatomy of modified anterolateral approach for type C fractures of the distal femur
目的 为改良股前外侧入路治疗股骨远端C型骨折提供解剖学基础。 方法 福尔马林防腐成人下肢标本12例，解剖观察大腿下段前外侧的主要肌肉、韧带的分布；采用改良前外侧手术入路，测量该入路相关的神经、血管走行特点。 结果 改良股前外侧入路可充分显露股骨远端，不损伤重要神经血管，不损伤髂胫束并减少了对股四头肌的损伤，有效地保护了伸膝装置。 结论 改良股前外侧入路治疗股骨远端C型骨折具有安全，损伤较小，暴露充分等优点，有一定的推广价值。
Objective To provide anatomic basis for treating type C fractures of the distal femur by the modified anterolateral approach of the thigh. Methods Main anterolateral muscles, ligaments were observed on 12 lower limbs of adult cadavers; the modified anterolateral approach was used, and the vessels and nerves related to the posterolateral approach were measured. Results The modified anterolateral approach could fully expose the distal femur without risk of injuring the important nerves and vessels. What's more, it did not affectthe iliotibial band and could attenuate the damage to the quadriceps femoris, which could effectivelyprotectthe extensor mechanism of the knee joint. Conclusions The treatment of the fracture of the distal femur by the modified anterolateral approach is safe, less traumatic and and greater in exposure.it is worth of further promotion.
