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. 相似文献

BACKGROUND: Distal tibial reconstruction with use of an external fixator when there is bone loss, limb-length discrepancy, and/or ankle instability is associated with many problems. The technique of limb-lengthening, ankle arthrodesis, and segmental transfer over an intramedullary nail has been introduced to overcome these problems. The present study investigates this combined technique. METHODS: Between 2002 and 2005, six patients, who ranged from seventeen to seventy years old, underwent distal tibial reconstruction and ankle arthrodesis with use of a circular external fixator and an intramedullary nail to treat a distal tibial defect following resection for chronic osteomyelitis or tumor or to treat a limb-length discrepancy combined with ankle instability. Functional and radiographic results were evaluated, with use of the criteria described by Paley et al., at an average follow-up of thirty-four months. RESULTS: The mean size of the bone defects in three patients was 5.3 cm (2, 7, and 7 cm), and the mean amount of the limb-shortening in four patients was 5.25 cm (range, 4 to 6 cm). The mean external fixation time was 3.5 months, and the mean external fixator index was 0.57 mo/cm. There was no recurrence of infection in the two patients with osteomyelitis. All six patients had excellent bone results, and the functional results were excellent for two patients and good for four patients. There were four complications, three of which were categorized, according to Paley, as a problem (a difficulty that occurs during lengthening and is resolved without operative intervention) and one that was categorized as an obstacle (a difficulty that occurs during lengthening and needs operative treatment). CONCLUSIONS: The combined technique is an improvement over the classic external fixation techniques of distal tibial reconstruction with ankle arthrodesis. It reduces the duration of external fixation, thus increasing patient acceptance, and it is associated with a low complication rate facilitating more rapid rehabilitation. 相似文献

BACKGROUND: Although long bone defects may be treated by callus distraction, frequent complications arise from the long duration of external fixation. To reduce such complications, bone transport over an intramedullary nail (BTON) has been done for tibial bone defect. METHODS: In 12 patients (mean age, 46.1 years) of chronic osteomyelitis or bone defect, segmental transport was done using external fixator over an intramedullary nail. Prior to the index procedure, all patients had had serial debridements and five required myocutaneous or free flaps for covering of soft tissue defects. Using Mekhail's criteria, functional results were evaluated. RESULTS: The mean transported amount was 5.9 (range, 3.5-12) cm. The mean external fixation index was 26 days/cm, and healing index was 62.6 days/cm. The primary union of distraction and docking site was achieved in all, except for one failure in union at the docking site, which required another bone graft. Except for one patient with associated ankle injury, all had excellent or good functions. There was one recurrence of osteomyelitis and one procurvatum of the proximal tibia of 10 degrees . CONCLUSION: BTON may be a successful method in tibial reconstruction and allows patients to return to daily life earlier with relatively few complications. 相似文献

Ilizarov bone transport for massive tibial bone defects 总被引:6,自引:0,他引:6
Abdel-Aal AM 《Orthopedics》2006,29(1):70-74
This article reports the treatment of massive tibial bone defects by bone transport using the Ilizarov external fixator. Fifteen patients were treated using this technique (3 females and 12 males). The defect size ranged between 7 and 22 cm (average: 10.6 cm). Etiology was infected nonunion in 9 patients, nonunion in 5 patients, and recurrent giant-cell tumor in 1 patient. The affected site was the tibial diaphysis in 10 patients, the lower tibial metaphysis in 4, and the upper tibial epiphysis in 1 patient. The external fixation time ranged from 9 months to 17 months (average: 12.27 months). External fixation index ranged from 21.8 to 42.5 day/cm (average: 35.7 day/cm). There was no recurrence of infection, no recurrence of the tumor, nor fractures after frame removal. We had to graft the docking site in 2 patients for delayed union and 2 patients developed equinus deformity and had tenoplasty for the Achilles tendon at the time of frame removal. Four patients had pin tract infection at > or =1 of the wires and this was successfully treated by antibiotic injection at the wire site. This study suggests that Ilizarov bone transport is a reliable method to fill massive bone defects. 相似文献

Segment transport employing intramedullary devices in tibial bone defects following trauma and infection 总被引:2,自引:0,他引:2
OBJECTIVES: To compare two different methods of segment transport in posttraumatic and postseptic tibial defects by employing intramedullary tibial nails as the fixation system and to evaluate differences in the complication rate between external fixation and wire towropes as the transport system. DESIGN: Randomized, prospective, nonblinded study. SETTING: Level 1 trauma center. PATIENTS: Thirty patients with posttraumatic or postseptic defects of the tibial shaft were admitted at our center between January 1994 and December 1995. For study purposes, they were divided into two groups with fifteen patients in each. METHODS: All thirty patients underwent a standardized therapy protocol consisting of three phases: (a) eradication of infection, (b) restoration of soft tissue defects, and (c) bone segment transport. The first two phases were identical for both groups. The third phase was different: in Group A transport of the segment was performed with a combination of intramedullary nail and wire towrope; in Group B the intramedullary nail was combined with an external fixation device. We then evaluated both subjective data (patient comfort, restrictions in physiotherapy) and objective data (mobility of knee and ankle joint, transport time, reoperations, complications) to determine treatment success. RESULTS: Both methods are useful for segment transport in patients with tibial shaft defects following trauma and infection. The relative transport time was shorter in Group A than in Group B (12.2 versus 13.7 days/centimeter; p = 0.002). Group B also recorded a significantly higher complication rate than did Group A (septic complications, twenty-six versus six events; necessary recorticotomies, four versus zero events). CONCLUSIONS: An intramedullary nail and wire towrope proves to be a reliable combination for segment transport in tibial defects following trauma and infection and provides a relatively high patient comfort rate and a low complication rate. 相似文献
