Spondyloepiphyseal dysplasia is a type II collagenopathy with resulting spinal and extremity deformities. The clinical manifestations include short stature, hearing loss, kyphoscoliosis, and complex knee deformities. Genu recurvatum can be a challenging surgical problem, especially when the deformity is severe. In this report, we present a case of severe genu recurvatum in a 14-year-old female that was treated with a pediatric circular fixator with the addition of two z-plates. At one year follow-up, the patient demonstrated improved knee range of motion, tibial alignment with the radiographic union, and good ambulatory ability. The hexapod fixator with the use of two Z-plates may help ensure that appropriate ring strut angles are achieved. Larger studies regarding the efficacy of this treatment option in spondyloepiphyseal dysplasia are required.
脊椎骨骺发育不良是一种II型胶原病,可导致脊柱和四肢畸形。临床表现包括身材矮小、听力丧失、脊柱侧凸和复杂的膝关节畸形。膝反屈可能是一个具有挑战性的手术问题,尤其是当畸形严重时。在本报告中,我们介绍了一名14岁女性严重膝反屈的病例,该患者接受了儿童环形固定器治疗,并附加了两个Z形钢板。在一年的随访中,患者的膝关节活动范围有所改善,胫骨对线良好且影像学显示骨愈合,行走能力良好。使用两个Z形钢板的六足固定器可能有助于确保获得合适的环形支柱角度。需要针对这种治疗方案在脊椎骨骺发育不良中的疗效进行更大规模的研究。
