We report of a ten year old patient with soft tissue damage and bone defect of the tibia as a sequel of osteomyelitis. After excision and stabilization with an Ilizarov fixateur segment transportation was started. In order to avoid skin and soft tissue entrapment in the docking region, we used a metal cage as a space provider, which was shortened as segment transportation progressed. To our knowledge this simple method has not been described so far.Résumé Nous présentons le cas d'un enfant de dix ans, victime de mine, qui a développé une ostéomyélite sévè-re avec dégats importants des parties molles et défect osseux du tibia. Après excision et stabilisation avec un fixateur externe d'Ilizarov le transport d'un segment osseux a eté commencé. Pour éviter l'incarcération des parties molles au niveau de la zone de réunion osseuse, on a utilisé une cage métallique pour maintenir l'espace interfragmentaire. On a raccourcit la cage avec la progression du transport du segment. A notre connaissance cette méthode simple n'a pas eté décrite jusqu'à présent.
IntroductionIn treating chronic osteomyelitis with sequester and posttraumatic defects stabilization of the limb can be achieved by applying an Ilizarov ring fixateur [3][4][5]. This method can be used for segment transportation as well. Little attention has been paid to the problem of how to preserve the space for the transported segment and how to avoid tissue entrapment in the docking region. To our knowledge no methods other than surgical excision of interfering tissue have been published to solve this problem. We report on a patient in which a metal cage usually used in spine surgery was inserted to avoid deep and large entrapment of the skin in the docking area.
Case reportA ten year old African boy sustained an open tibial fracture with soft tissue damage in a landmine accident during the Angolan war. Six month after the accident the child was admitted to our department. The general condition as well as the local status was poor and a severe osteomyelitis with sequestration ( Fig. 1) had developed. A soft tissue defect (approximately 20×5cm) with bad smelling pus was apparent on the lower leg (Fig. 2). The complete cortical bone of the anterior tibia had disappeared. Infected soft tissue as well as the osteomyelitic bone and the sequester were removed and excessive debridement was carried out. The lower leg was stabilised with an Ilizarov ring fixateur. Antibiotic treatment was given parenterally.The segment transport with the Ilizarov fixateur was started after improvement of the condition. Using vessel loops we did skin banding in order to achieve some soft tissue coverage. We had been able to leave a small ventral skin bridge above the area of the removed tissue. This skin bridge dropped down and started to heal to the dorsal soft tissue leaving no tunnel for the transported segment to reach the distal bone fragment. The situation was endangered of skin entrapment in the docking area. To avoid this we inserted a cage (normally used in spine surgery) o...
