我们对18例股骨内假体患者进行了步态分析：12例远端，3例近端，3例全端。术后平均随访12年（0.6 ~ 19年）。测量步态参数为步行速度、步长、站立阶段和摇摆阶段持续时间。在自由步伐行走时测定双腿的髋关节、膝关节和踝关节的几何角度。对所有患者进行肌肉骨骼肿瘤协会（MSTS）的功能结局评分和活动评分。平均自由步行走速度是正常人的88%。未受累腿的步长大于受累腿的步长。涉入腿的摆动阶段比未涉入腿长，涉入腿的站立阶段比未涉入腿短。角度测量显示受累腿部有三种异常模式：10例患者膝关节僵硬步态，6例患者膝关节屈曲步态，9例患者髋关节屈曲-伸展异常模式。未受累腿的几何形状正常。MSTS平均评分为22分（72%）。这显示出与步行得分显著正相关，但与任何时间变量无关。我们的研究结果表明，无论是有意识的还是无意识的，在相关腿上的负荷时间都减少了。需要后续研究来评估观察到的不对称步态模式和异常的角度测量结果对假体相关并发症发展的影响。
We performed gait analysis in 18 patients with a femoral endoprosthesis: 12 distal, 3 proximal and 3 total. Follow-up after surgery was mean 12 (0.6-19) years. The gait parameters measured were walking velocity, step length, duration of stance phase and swing phase. Goniometry of the hip, knee and ankle in both legs was determined during free-paced walking. The functional outcome score of the Musculoskeletal Tumor Society (MSTS) and the Ambulation score were also assessed in all patients.The mean free-paced walking velocity was 88% of normal. The step length of the uninvolved leg was longer than that of the involved one. The swing phase of the involved leg was longer than that of the uninvolved leg, and the stance phase of the involved leg was shorter than that of the uninvolved leg. Goniometry showed three abnormal patterns in the involved leg: a stiff knee gait in 10 patients, a flexed knee gait in 6, and an abnormal flexion-extension pattern in the hip in 9. Goniometry of the uninvolved leg was normal. The mean MSTS score was 22 points (72%). This showed a significant positive correlation to the Ambulation score, but no correlation to any of the temporal variables.Our findings indicate that the time of load on the involved leg, whether conscious or not, is reduced. Follow-up studies are needed to evaluate the effects of the asymmetrical gait pattern observed and the abnormal goniometric results on the development of endoprosthesis-related complications.
