In treatment of tumors, we usually reconstruct after resection of the entire femur using only metallic modular endoprostheses among many procedures and defined it as a total femur replacement. We studied the interrelation between the preservation of rectus femoris and the functional outcome after total femur replacement.
We rated the functional outcomes of 21 patients who underwent total femur replacement. We categorized the subjects into 2 groups: group A (rectus femoris preserved) and group B (rectus femoris unpreserved). We examined them based on the Mann-Whitney U test between the 2 groups in average through the Musculoskeletal Tumor Society functional scores.
The average score of group A was 20 of 25 (11-25; 80%), whereas the average score of group B was 10 of 25 (4-13; 40%). There was significant difference between the groups (P = 0.00168877).
We found that the preservation of rectus femoris is imperative for achieving the favorable functional outcome in total femur replacement.
在肿瘤治疗中，在多种手术方式中，我们通常在切除整个股骨后仅使用金属模块化假体进行重建，并将其定义为全股骨置换。我们研究了股直肌保留与全股骨置换术后功能结果之间的相互关系。
我们对21例行全股骨置换术的患者的功能结果进行了评分。我们将受试者分为两组：A组（保留股直肌）和B组（未保留股直肌）。我们通过肌肉骨骼肿瘤学会功能评分，在两组之间平均基于曼-惠特尼U检验对他们进行了检查。
A组的平均得分为25分中的20分（11 - 25分；80%），而B组的平均得分为25分中的10分（4 - 13分；40%）。两组之间存在显著差异（P = 0.00168877）。
我们发现，保留股直肌对于在全股骨置换术中获得良好的功能结果至关重要。
