Segmental bone defects following osteomyelitis in pediatric age group may require specifically designed surgical options. Clinical and radiographic elements dictate the option. Different elements play a role on the surgeon's choice. Among them, the size of the defect, the size and the quality of the bone stock available, the status of the skin envelope, the involvement of the adjacent joint. When conditions occur, vascularized fibula flap may represent a solution in managing defects of the long bones even during the early years of life. A retrospective study, covering the period between October 2013 and September 2015, was done. Fourteen patients, nine males, five females, aged 2–13 years, with mean skeletal defect of 8.6 cm (range, 5 to 14 cm), were treated; the mean graft length was of 8.3 cm. The bones involved were femur (4), radius (4), tibia (3) and humerus (3). In 5 cases fibula with its epiphysis was used, in 5 cases the flap was osteocutaneous and in the remaining 4 cases only fibula shaft was utilized. After an average time of 8 months from eradication of infection, the procedure was carried out and the flap was stabilized with external fixators, Kirschner's wires or mini-plate. No graft augmentation was used.Aim
Method
Scaphoid non-unions can result in debilitating wrist problems. This study compared treatment of scaphoid non-unions using either a non vascularised (NVBG) or a vascularised bone graft (VBG). Twenty one cases of scaphoid non-unions were treated by two surgeons between 2005 and 2008 using either a NVBG from the iliac crest or a VBG from the radius based on a 1,2 intercompartmental supraretinacular artery pedicle.Purpose
Method
We did a retrospective comparative analysis of twenty five patients treated with Ilizarov bone transport [IBT] and twenty one patients treated with vascularised fibular graft [VFG] from 1994 to 2003 in one institution, for post traumatic tibial bone defects of more than six centimetres. The aim of the study was to find out if there were any differences in achieving radiological end points, bone and functional score and return to work (final outcome), hospital stay and operating time (logistic factors) and complication rates. The mean defect size in the IBT group was 11.9 centimetres and in the VFG group 14.6 centimetres. Twenty one and sixteen patients in the IBT and VFG group respectively achieved the radiological end point that is union of the defect and graft hypertrophy [p 0.5]. Nineteen patients in the IBT group and fifteen in the VFG group returned to productive work [p 0.72]. Bone and functional results were analyzed by Paley's evaluation system and there were no significant differences in the two groups of patients [bone result p 0.97 and functional result p 0.1]. The logistic factors were significantly less of IBT group [p < 0.05]. Two patients in the IBT group and one patient in the VFG group had amputation and one patient in VFG group died. Three cases in the VFG group had flap loss. Stress fracture of the graft occurred in eight patients in the VFG group [p 0.0007]. The final outcome was same in both groups. Hospital stay, operating time and refractures were significantly less in IBT group.
A defect following resection of Giant Cell Tumour of the distal radius (GCT-DR) is reconstructed by either vascularised free fibular transfer (VFF) or non-vascularised structural iliac crest transfer (NIC). The purpose of this study was to compare these procedures. Twenty-seven patients at two centres were identified, 14 underwent VFF and 13 NIC. The two groups were comparable for age, sex, and tumour grade. Functional outcomes were assessed with TESS, MSTS, and DASH. In the VFF group, ankle joint morbidity was assessed with the Ankle Osteoarthritis Scale. In the NIC group, iliac crest morbidity was assessed with a short questionnaire.Objectives
Methods
Purpose. We retrospectively evaluated the outcome of fibula grafts in upper limb post infectious diaphyseal gap nonunions and assessed the following modifiers: age, site, vascularised/ nonvascularised, and length of the graft on time to union, graft incorporation, complication rate and reoperation rate. Methods. Thirty seven paediatric upper limb segmental defects treated over a period of 10 years were identified. Twenty two post septic defects in 21 children were treated with intramedullary fixation and vascularised/ nonvascularised fibula grafting. Union time was assessed from records and radiographs. Graft incorporation was assessed using Pixel value ratio (Hazra et al). Complications were defined as nonunion, delayed union, implant failure, refractures, graft loss and infection. Results. Twenty one children with 22 nonunions, 9 boys and 12 girls, mean age 6.5 years were followed up for a mean of 24 months. Defects (humerus-8, radius-8, ulna-6) ranged from 10 mm to 85 mm before surgery. Seven vascularised grafts(mean length = 69.9 mm) 3 in ulna and 4 in radius and 14 nonvascularised (48.8 mm) were 8 in humerus, 4 in radius, 3 in ulna. Primary union was 81% at a mean of 4.7 months. Mean pixel value for graft incorporation was 1.3 (SD = 0.2) on immediate postoperative radiograph and 1.08 (SD 0.16) at mean of 2 years. Complications included nonunion requiring surgery in 4, delayed union in 6, wire migration in 6, refractures in 4, infection reactivation in 2 with loss of graft in 1. Time to union was 5.5 (SD 2.9) months in nonvascularised and 3.1 (SD 0.6) in vascualrised group (P = 0.04). Complication rate was 1.2 and 0.2 in nonvascularised and vascularised grafts(p = 0.04). Bone, age and the graft length did not significantly affect union time, graft incorporation, complication and reoperation rate. The complication rate was significantly higher in children ≤8 year; however other outcomes were not significantly different. Conclusion.
