Abstract：
UNASSIGNED: Synovial chondromatosis is a condition where the cells lining a joint form benign cartilaginous tumors. This benign cartilage metaplasia results in the formation of multiple intra-articular loose bodies within a joint.
UNASSIGNED: This case is a 59-year-old female that presented with constant, severe left hip pain that was localized to the groin and began 2 years ago. There were severe limitation of hip flexion, extension, pain on internal rotation, and a half inch left leg shortening. Radiographs demonstrated multiple round opacities surrounding the left femoral neck. MRI showed numerous, small rounded intra-articular loose bodies, measuring about 5-6 mm each within the left hip joint.
UNASSIGNED: A lateral approach toward the hip was used to perform an osteotomy at the portion of the greater trochanter. The hip capsule was identified and an S-shaped incision was then made through the capsule. Repetitive hip dislocations allowed for improved visualization making further removal of the difficult fragments much easier. The capsule was closed and the osteotomy was reattached. Range of motion was found to be significantly improved compared to preoperatively. No further fixation was necessary and the patient\'s subcutaneous tissue was closed in normal fashion.
UNASSIGNED: The technique used in our case involves a lateral approach with a trochanteric flip osteotomy to preserve the medial femoral circumflex artery and external rotators. This is similar to the approach described by Ganz in 2001 who used a posterior approach. Following the approach, the hip is then dislocated and exposed anteriorly with full visualization of the joint with a gap of about 11 cm between the femoral head and acetabulum. Surgical dislocation allows for the removal of difficult chondromas and osteophytes around the femoral head-and-neck junction. Multiple studies support the idea of surgical dislocation as an exceptional treatment method for SC.

摘要：
未经证实：滑膜软骨瘤病是指关节内的细胞形成良性软骨肿瘤。这种良性软骨化生导致在关节内形成多个关节内松散体。
未经调查：这是一个59岁的女性，严重的左髋部疼痛位于腹股沟，2年前开始。髋关节屈曲严重受限，扩展,内旋疼痛，和半英寸的左腿缩短。射线照片显示左股骨颈周围有多个圆形混浊。MRI显示大量,小圆形关节内松散体，在左髋关节内约5-6毫米。
UNASSIGNED：使用髋部外侧入路在大转子部分进行截骨。识别髋囊,然后通过囊形成S形切口。重复的髋关节脱位可以改善可视化，从而更容易地进一步去除困难的碎片。关闭胶囊并重新连接截骨术。与术前相比，发现运动范围显着改善。无需进一步固定，患者的皮下组织以正常方式闭合。
UNASSIGNED：我们案例中使用的技术涉及采用股骨转子翻转截骨术的外侧入路，以保留股骨内侧旋支动脉和外部转子。这类似于Ganz在2001年使用后入路描述的方法。按照这种方法，然后，髋关节脱位并向前暴露，关节完全可视化，股骨头和髋臼之间的间隙约为11厘米。手术脱位可以去除股骨头和颈部交界处周围困难的软骨瘤和骨赘。多项研究支持手术脱位作为SC的特殊治疗方法的想法。
