Ilizarov segmental bone transport of infected tibial nonunions requiring extensive debridement with an average distraction length of 9,5 centimetres. Is it safe?

ObjectivesTo evaluate the results of one stage radical debridement and segmental bone transport with circular fixator in the treatment of infected tibial non-union requiring extensive debridement with an average defect size of 8 cm and distraction length of 9,5 cm.DesignRetrospective study.SettingLevel I trauma centre at an academic university hospital.PatientsThirty patients with infected tibial non-union with an average of 2,9 previous failed operations after a mean 12,5 months post-injury were treated consecutively. The mean age was 39,5 years (R:16–68). After radical debridement and irrigation, all patients were treated with segmental bone transport using Ilizarov circular fixator. All patients except 3, managed with an open docking protocol without bone grafting. In 2 patients a planned ankle arthrodesis with transport was done.Main outcome measurementsBone union, resolution of infection, external fixation index (EFI), external fixation time (EFT), bone and functional results for this big defect size.ResultsUnion and eradication of infection was achieved in all patients. Mean follow-up was 32,5 months (R: 12–72 mo.) The average bone defect after debridement was measured 8.1 cm (R, 6–15). The total distraction length to restore the debridement defect and previous LLD was 9,5 cm (R, 6–15). The mean external fixation time was 13,7 months; the mean external fixation index was 1,49 mo./cm. One non-union, one refracture and one late valgus deformity was managed successfully with plating or nailing and all were healed uneventfully at the completion of the treatment. According to Paley & Maar and Katsenis criteria, the bone results were excellent in 24 and good in 6, functional scores were excellent in 21, good in 7, and fair in 2 patients. Minor complications were 1,36 per patient, major complications were 0,4 per patient and permanent complications were 0,2 per patient in the study group.ConclusionIn the management of large post-infectious bone defects requiring an average 9,5 cm distraction; segmental bone transport is safe in terms of union and eradication of infection. The EFI, EFT, complications, bone and functional results do not differ from the other published studies with smaller defect size.

The reconstruction of defects in the femoral shaft with vascularized transfers of fibular bone

Seven major reconstructions of the femoral shaft using a vascularized graft of bone from the fibula were performed at the Massachusetts General Hospital from 1981 to 1984. Three patients had a post-traumatic infected non-union; one, extensive osteomyelitis of the femoral shaft; one, a fractured allograft; one, an atrophic non-union associated with radiation therapy; and one, post-traumatic loss of a ten-centimeter segment of bone. Six of the seven patients had a skeletal femoral defect, ranging from seven to fifteen centimeters in length. The average length of fibula that was used for reconstruction was 19.6 centimeters. Primary skeletal union occurred in five of the seven patients. Two patients had healing only at the distal junction and required a conventional bone graft and supplementary internal fixation of the proximal junction. At an average length of follow-up of thirty-four months, all of the patients were able to walk. Only two patients, both of whom had an extreme limb-length discrepancy, required additional support.     

Comparison of internal bone transport and vascularized fibular grafting for femoral bone defects

OBJECTIVE: To compare results between vascularized fibular grafting and internal bone transport for large bone defects of the femur. DESIGN: Retrospective review of patients. SETTING: University teaching hospitals. PATIENTS: This study included 37 patients with femoral bone loss: 20 patients were treated with internal bone transport and seventeen patients were treated with vascularized fibular grafting. MAIN OUTCOME MEASUREMENTS: The outcomes investigated were external fixation time, external fixation index, bone results (union, infection, deformity, leg length discrepancy), and functional results. RESULTS: The mean amount of filled defect was 8.4 cm with internal bone transport and 8.9 cm with vascularized fibular grafting. The external fixation index was 1.4 months/cm with internal bone transport and 1 month/cm with vascularized fibular grafting. The bone results and functional results of the internal bone transport were excellent in 65% and 0%, good in 5% and 45%, fair in 5% and 40%, poor in 25% and 15%, respectively, whereas those of the vascularized fibular grafting were excellent in 35% and 0%, good in 25% and 47%, fair in 5% and 35%, and poor in 35% and 18%. CONCLUSION: With vascularized fibular grafting, careful monitoring of circulation and early intervention surgery is necessary to avoid vascular failure. With internal bone transport, repeated radical debridement until control of infection is achieved, bone grafting at the docking site for early union, and avoiding stress fracture are recommended to improve bone results.     

Tetrafocal (three osteotomies) and pentafocal (four osteotomies) bone transport using Ilizarov technique in the treatment of distal tibial defect—preliminary outcomes of 12 cases and a description of the surgical technique

ObjectiveTo evaluate the preliminary outcomes of tetrafocal (three osteotomies) and pentafocal (four osteotomies) bone transport using Ilizarov technique for the treatment of distal tibial defect and describe the surgical technique.MethodsA total of 12 eligible patients with distal tibial defect > 6 cm caused by direct trauma or posttraumatic osteomyelitis who were admitted to our institution from January 2017 to January 2019 were treated by tetrafocal or pentafocal bone transport using Ilizarov technique. Detailed demographic data, including age, sex, etiology, defect size, number of osteotomies (three or four), external fixation time (EFT) and external fixation index (EFI), were collected, and the bone and functional outcomes were evaluated by the Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system. Complications during the surgery and the follow-up period were recorded and evaluated by the Paley classification at a minimum follow-up of two years after removal of the fixator.ResultsThere were 9 men and 3 women with an average age of 37.4±7.8 years. The etiology included posttraumatic osteomyelitis in 8 cases and posttraumatic bone loss in 4 cases. The mean bone defect after radical debridement was 7.1±0.6 cm. Tetrafocal bone transport was applied in 9 cases, and pentafocal bone transport was applied in 3 cases. The average EFT and EFI were 5.2±0.8 months and 0.7±0.2 months/cm, respectively. The average time of follow-up after removal of the external fixator was 28.5±3.3 months without recurrence of osteomyelitis. The bone results were good in 7 cases, fair in 4 cases, and poor in 1 case, and the functional results were good in 5 cases, fair in 6 cases, and poor in 1 case. The most common complication was pin tract infection, which occurred in all cases, but there were no major complications, such as nerve or vascular injury.ConclusionTetrafocal and pentafocal bone transport using Ilizarov technique could be an alternative treatment option in selected cases with distal tibial defect > 6 cm. It could shorten the distraction period, fasten regeneration, and reduce the associated complications.

Masquelet technique versus Ilizarov bone transport for reconstruction of lower extremity bone defects following posttraumatic osteomyelitis

ObjectiveThis study was to compare the effectiveness of Masquelet technique versus Ilizarov bone transport in the treatment of lower extremity bone defects following posttraumatic osteomyelitis.Patients and methodsWe retrospectively reviewed 39 patients who had been treated at our department for lower extremity bone defects following posttraumatic osteomyelitis. They were 30 males and 9 females with a mean age of 39.18 (range, 12–63 years). The infected bone defects involved 26 tibias and 13 femurs. The mean length of the bone defects after radical debridement was 6.76 cm (range, 2.7–15.7 cm). Masquelet technique (MT, group A) was used in 20 patients and Ilizarov bone transport (IBT, group B) in 19 ones. The measurements were bone outcomes (union, deformity, infection and leg-length discrepancy) and functional outcomes (significant limping, joint contracture, soft tissue dystrophy, pain and inactivity).ResultsThe mean follow-up after removal of the apparatus was 25.26 months (range, 14–51 months). The mean finite fixator time was 10.15 months (range, 8–14 months) in group A versus 17.21 months (range, 11–24 months) in group B. The bone outcomes were similar between groups A and B [excellent (5 vs. 7), good (10 vs.9), fair (4 vs. 2) and poor (1 vs. 1)]; group A showed better functional outcomes than group B [excellent (8 vs. 3), good (9 vs. 6), fair (3 vs. 8) and poor (0 vs. 2)].ConclusionsIn the treatment of segmental lower extremity bone defects following posttraumatic osteomyelitis, both IBT and MT can lead to satisfactory bone results while MT had better functional results, especially in femoral cases. IBT should be preferred in cases of limb deformity and MT may be a better choice in cases of periarticular bone defects.
