We report the case of a pediatric patient with Ewing’s sarcoma of the tibia treated with vascularized fibular autograft where the resulting limb deformity and leg length discrepancy (LLD) were corrected using Ilizarov external fixator. A 14-year-old girl presented to our outpatient clinic with a deformity of the right proximal and distal tibia and an 11.7 cm of LLD after tumor reconstruction surgery. Deformity correction and limb lengthening were simultaneously performed using double corticotomy on the right proximal and distal tibia. One year postoperatively, the union of the right proximal tibia had progressed, but nonunion was observed at the right distal corticotomy site. To address this, osteosynthesis with tricortical iliac bone allograft was performed after the removal of the Ilizarov external fixator. After 6 months, the union of the distal tibia was confirmed, and the varus deformity of proximal and distal tibia improved. The LLD was also decreased, but the left lower limb was still longer by 3 cm. This report shows that vascularized fibular autografts can potentially be used for the gradual correction of LLD and deformities. However, for the treatment of multiple deformities in bones previously reconstructed with vascularized fibular graft, the possibility of impaired bone forming potential of the fibular graft should be considered.

The free vascularized fibular graft is nowadays the preferred technique for pediatric mandibular reconstruction. Despite the versatility and proven efficacy for restoring the facial appearance and maxillomandibular function, those mandibular reconstructions with free vascularized fibula associate difficulties for a simultaneous restoration of the alveolar height and facial contour, which are derived from the height discrepancy between the fibula and the native mandible. In addition, the donor-site growth and morbidity are of special concern in the pediatric patient. We report a novel technique for pediatric mandibular reconstruction, in an 11-year-old girl, using a combination of a bone allograft segment with a vascularized fibular periosteal flap (VFPF), after resection of an Ewing sarcoma located at the right body of the mandible. The patient has showed optimal cosmetic, functional, and radiological outcomes, which have been maintained for 2.5 years, without detecting donor-site complications. Through this original technique, and based on the powerful osteogenic and vasculogenic properties of the pediatric VFPFs, we could effectively reconstruct a large mandibular defect providing a functional and aesthetic reconstruction, while avoiding the potential morbidity associated with the fibula resection.

<p class="abstract"><strong>Background:</strong> Determining the incidence of deep venous thrombosis (DVT), a prospective study, in patients treated with Ilizarov external fixators for lower extremity fractures, fracture non unions or deformity correction.</p><p class="abstract"><strong>Methods:</strong> A Prospective, observational and cross sectional study. 49 Patients with complex lower extremity injuries, deformities and non-union of fractures were treated with Ilizarov external fixator application, were assessed clinically and radiological (Venous Doppler) at regular intervals- 6 days post-surgery then at 6 weeks, 12 weeks and between 4 to 6 months post-operative. None were given chemoprophylaxis for the prevention of DVT and everyone were assessed pre operatively with a questionnaire and wells criteria was taken for assessment of high risk for developing venous thrombosis.

Abstract. Mycobacterium senegalense infection is rare. We present the third documented case of M. senegalense infection and the first to involve the musculoskeletal system. A 55-year old immunocompetent male developed chronic osteomyelitis of the ankle and required antibiotic spacers, an Ilizarov external fixator and multiple antibiotic regimens to eradicate the infection.

Technical Considerations

Supramalleolar osteotomies are performed to realign the distal tibia and to improve foot and ankle function. This procedure requires a thorough preoperative and intraoperative understanding of limb-deformity parameters and of the center of rotation of angulation method of surgical planning. Radiographic, gait, and clinical analyses along with intraoperative fluoroscopic images are paramount to deformity correction. This article describes the radiographic and clinical analyses and technical considerations in performing a focal dome supramalleolar osteotomy. (J Am Podiatr Med Assoc 95(1): 72–84, 2005)
