2 Case Report J Korean Soc Spine Surg Dec;24(4): Paraplegia in an nkylosing Spondylitis Patient with a Neglected Spine Fracture after Osteosynthesis for Fracture of the Femur - Case Report - Jae Won You, M.D., Sin Wook Kang, M.D., Hong Moon Sohn, M.D. Department of Orthopaedic Surgery, School of Medicine, Chosun University, Gwangju, Korea Study Design: Case report. Objectives: To report a case of paraplegia in a patient with thoracic kyphosis after osteosynthesis for a fracture of the femur. Summary of the Literature Review: There are few reports about cases of paraplegia after low extremity fracture surgery in patients with thoracic kyphosis with ankylosing spondylitis. Materials and Methods: n 86-year-old female patient presented with right hip pain. She had undergone surgery for an intertrochanteric fracture of the femur in the supine position under general anesthesia. Immediately after surgery, she showed paraplegia. Postoperative thoracolumbar spine images revealed a fracture through the disc at T12 and L1. However, she did not complain of back pain or any neurologic deficits before surgery. Results: lthough the patient underwent emergent posterior decompression and fusion surgery, her neurologic compromise did not improve during 1 year of follow-up. Conclusions: It is necessary to check preoperative spine radiographs before surgery in elderly patients who have a kyphotic deformity and lower extremity fractures. Surgeons should consider changing the position of the patient and the type of anesthesia used during surgery when spine stability is in doubt. Key words: nkylosing spondylitis, Spine fracture, Lower extremity fracture, Paraplegia, Thoracic kyphosis 강직성척추염은전, 후종인대와황색인대및극간인대의골화와추간판의석회화로상하척추가융합되어탄력성, 운동성의상실과긴지렛대작용으로가장약한부위에응력이집중되고골다공증과동반되어사소한외상에도골절이잘발생한다. 강직성척추염은흉요추부의원형척추후만증 (round kyphosis) 를일으키고, 국소골절이있을경우예각상척추후만증 (acute angular kyphosis) 를일으키기도한다. 1) 후만변형이온상태에서골절이발생할경우주로추간판을통한골절부위전이전위가일어나신경학적증상이발생할수있고상하관절이모두유합되어있는상태라서골절부위가상대적으로매우불안정한상태라서가능한빨리고정수술을해야한다. 저자들이경험한증례는낙상에의해우측고관절전자간골절및추간판을통해제 12흉추- 제 1요추간골절및탈구가발생하였으나전혀신경학적인증상은없었다. 하지만전신마취및우측고관절골절수술에서앙와위자세를취하였고, 이로인한제 12흉추- 제 1요추간탈구악화로인한척수원추증후군이발생하여척추에대한응급수술시행하였던경우였다. 이 증례는고령의척추변형을동반한환자에서반드시척추방사 선사진을확인하고환자에따라수술자세의변화가필요함을 일깨워주는좋은경험이기에보고하는바이다. 본연구는본원기관생명윤리위원회의승인을얻어연구를 진행하였다 (IR No ).

Postoperative pelvic radiographs show that the fracture was fixed by a cephalomedullary nail (). Fig. 2. Lumbar spine radiography before hip surgery showed bamboo spine with extensive fusion across the entire spine (). On the lateral view, there was a gap between T12 and L1 (). Thoracolumbar lateral spine radiographs after hip surgery show a more displaced thoracolumbar fracture and deviated spine alignment (C). C 247

요추단순방사선상척추전체에걸쳐광범위한척추유합으로대나무척추 (bamboo spine) 소견을나타냈고 (Fig. 2), 측면사진에서제 12흉추와제 1요추사이간격이벌어져있었고, 제 2요추압박골절로제 1요추체가전방으로전위되어있어제 12흉추- 제 1요추사이의추간판을통한골절로제 1요추의전방전위가발생하였던것으로추정할수있었고, 흉요추부에원형척추후만증이관찰되었다 (Fig.

이를통해제 12흉추- 제 1요추의골절및탈구로발생한척추원추증후군으로진단할수있었다. 환자의마비를인지한이후약 8시간경과이후응급수술로후방접근법을통한골절의정복및후방기기고정술, 감압술, 골유합술을시행하였다. 수술소견에서제 1요추체가전하방으로전위되어있었고제 1요추의좌측척추경골절및우측횡돌기의골절그리고극돌기의골절소견관찰되었다.

Patel 등 3) 에의하면강직성척추염환자에서발생하는척추골절은대부분이응력이집중되는경추부의추간판을통한골절 (transdiscal fracture) 이며흉요추부의경우운동성이남아있는흉요추부이행부 (thoraco-lumbar junction) 에서잘발생하며추체를통한 (transvertebral) 골절은드물다고보고하였다. 강직성척추염의척추골절은매우불안정하며신경학적증상이경추골절의경우많게는 91% 에서동반되고, 흉-요추골절의경우빈도가경추골절에비하여드물지만 33% 의신경학적증상이동반된다고한다. 4) Good 5) 은전신마취하에고관절조작을한이후발생한요추골절및하반신마비가발생한강직성척추염환자를보고한바있다. Osgood 등 6) 은신경학적증상이있는경우에는감압술및내고정술을시행해야한다고주장하였다. 그리고치료시에강직성척추염에서발생한골절의치료는가벼운외상등에의한골절의발생으로과신전손상과같은손상기전에중점을두 어강직성척추염의병적특성인골다공증에대한고려가필요하다. 특히 Ghozlani 등 7) 은강직성척추염에서작은외상과함께골질의저하를동반한골다공증이강직성척추염에서척추골절이발생하는부수적인원인이아닌주원인이라고주장하였다. Olerud 등 8) 은골다공증이심한강직성척추염환자에서발생한제 12흉추의골절에대하여단순감압술및후방기기고정술후금속기기의이완을경험하였다고하며, 전후방고정술을동시에시행한경우기기의이완이없음을강조하며전후방고정술을시행하자고하였다. 저자들은후방접근법을통한골절의정복및후방기기고정술을시행하였고후궁판을충분히노출시켜망상골이최대한이식골과많이접촉할수있도록한후이식부위에충분한양의동종골이식을하는후외방골유합술을시행하였다. 저자들이경험한증례에서는수술부위가아닌척추손상을간과하여수술적치료이후하지마비가발생하였고이후이환기간의증가및재수술의위험도증가, 의료비증가라는손실이발생하였다. Danish 등 9) 은적절한처치를시행하여도신경학적회복이관찰되는예는드물어수술시행전일차적인예방을하는것이중요하다고하였다. 따라서강직성척추염이있는환자및심한후만변형이있는고령의환자에대해서는환자를이동시키거나, 자세변경, 전신마취하수술진행시반드시척추골절에대한위험성을인지하고대비하여야한다. REFERENCES 1.
