Many conditions produce femoral deformities that complicate primary total hip arthroplasty (THA). In each patient, treatment must be individualized to address the level of the deformity, the type of deformity, and bone quality, as well as surgeon preference. The S-ROM femoral component (DePuy Orthopaedics, Warsaw, Ind) is useful for many deformities from the level of the greater trochanter to the diaphysis. The S-ROM stem optimizes proximal and distal implant stability, allows maximal torsional stability during osteotomies, and permits easy adjustments to anteversion, offset, and leg length to provide optimal biomechanical reconstruction of the deformed femur in THA. Clinical results with few complications are achievable when using the S-ROM stem in complex deformities.
许多病症会导致股骨畸形，使初次全髋关节置换术（THA）变得复杂。对于每位患者，治疗必须个体化，以应对畸形的程度、畸形的类型、骨质以及外科医生的偏好。S-ROM股骨组件（美国印第安纳州华沙市的DePuy骨科公司）适用于从大转子水平到骨干的多种畸形。S-ROM柄优化了近端和远端植入物的稳定性，在截骨术期间允许最大程度的扭转稳定性，并便于对前倾角、偏心距和腿长进行调整，以在THA中为畸形股骨提供最佳的生物力学重建。在复杂畸形中使用S-ROM柄时，可取得并发症较少的临床效果。
