Hip dislocations excluding the anterior, posterior or central variety have rarely been published. We report an atypical and unclassifiable dislocation of the hip joint with incarceration of the capsule and labrum. The aim of the presentation was to describe an uncommon type of hip dislocation with entrapment of the soft tissue.
18-year-old patient, with no specific pathological history, was involved in a road traffic accident causing an unusual right hip joint displacement. After the first reduction, the control X-rays showed persistent enlargement of the joint line, strongly suggesting soft-tissue impingement. Computed tomography confirmed soft tissue entrapment in the anterior area between the head and the acetabulum. An Hueter approach carried out two weeks after the injury, revealed incarceration of the capsule and anterior labrum; which was released and repositioned. At 2-year follow-up, the patient complained of the pain and the Postel Merle d'Aubigné (PMA) score was 17. We observed the peritrochanteric calcifications but without signs of osteonecrosis femoral head.
Posterior and anterior hip dislocations are the main types. Forms excluding these types have rarely been reviewed. The last ones are usually surgical treatments, which help remove the obstacle, such as soft tissue or a bone fragment. However, the choice of approach depends on the displacement.
Atypical dislocation of the hip must be carefully reduced, due to the high risk of soft-tissue incarceration. An enlarged joint line on a control X-rays should lead to suspicion of a capsule or labrum interposition and a surgical strategy is required.
除前脱位、后脱位或中央脱位外的髋关节脱位鲜有报道。我们报告一例伴有关节囊和盂唇嵌顿的非典型且无法分类的髋关节脱位。本文的目的是描述一种伴有软组织嵌顿的罕见髋关节脱位类型。
一名18岁患者，无特殊病史，因道路交通事故导致右髋关节出现异常移位。首次复位后，对照X线片显示关节间隙持续增宽，强烈提示存在软组织撞击。计算机断层扫描证实股骨头与髋臼之间的前部区域有软组织嵌顿。受伤两周后采用许特尔入路，发现关节囊和前部盂唇嵌顿；予以松解并重新复位。在2年的随访中，患者诉说疼痛，波斯特尔·梅勒·德奥布涅（PMA）评分为17分。我们观察到转子周围有钙化，但无股骨头坏死迹象。
髋关节后脱位和前脱位是主要类型。除这些类型之外的情况很少被综述。最后这些情况通常采用手术治疗，以帮助清除障碍物，如软组织或骨碎片。然而，手术入路的选择取决于移位情况。
由于软组织嵌顿风险高，非典型髋关节脱位必须仔细复位。对照X线片上关节间隙增宽应引起对关节囊或盂唇嵌入的怀疑，并需要采取手术策略。
