Kyphectomy for congenital kyphosis due to meningomyelocele: a case treated with a modified approach to skin healing

Abstract

This study is a case report of a meningomyelocele patient with congenital kyphosis who was treated with kyphectomy and a special approach to soft tissue healing. The objective of this study is to show a step by step approach to surgical treatment and postoperative care of a meningomyelocele patient with congenital kyphosis. In meningomyelocele the incidence of kyphosis is around 12-20%. It may cause recurrent skin ulcerations, impaired sitting balance and respiratory compromise. Kyphectomy has first been described by Sharrard. This surgery is prone to complications including pseudoarthrosis, skin healing problems, recurrence of deformity and deep infections. A 15-year-old male presented with congenital kyphosis due to meningomyelocele. He had back pain, deformity and bedsores at the apex of the deformity. The wound cultures showed Staphylococcus epidermidis colonisation at the apex. He was given appropriate antibiotic prophylaxis. During surgery, the apex of the deformity was exposed through a spindle-shaped incision. After instrumentation and excision of the apex, correction was carried out by cantilever technique. Two screws were inserted to the bodies of L3 and T11. After the operation, the skin was closed in a reverse cross fashion. He was sent to hyperbaric oxygen treatment for prevention of a subsequent skin infection and for rapid healing of skin flaps post operation. The patient's deformity was corrected from a preoperative Cobb angle of 135°-15° postoperative. The skin healed without any problems. Preoperative culture and appropriate antibiotic prophylaxis, spindle-shaped incision, reverse cross-skin closure and postoperative hyperbaric oxygen treatment can be useful adjuncts to treatment in congenital kyphosis patients with myelomeningocele to prevent postoperative wound healing and infection problems. Reduction screws and intracorporeal compression screws help to reduce the amount of screws and aid in corection of the deformity.
