Results of vancomycin-impregnated cancellous bone grafting for infected tibial nonunion 总被引:2,自引:0,他引:2
Introduction Bone grafting plays a critical role in promoting bone healing in infected nonunion, although recurrent infection is of concern. Cancellous bone grafting as an antibiotic delivery system has been reported as an effective method to combat infections. In this study, we report the clinical results of vancomycin-impregnated cancellous bone grafting for the treatment of infected tibial nonunion.Materials and methods Between January 1996 and March 2001, 18 patients with infected tibial nonunion treated with vancomycin-impregnated cancellous bone grafting were available for follow-up. According to the Cierny-Mader classification, all patients belonged to type IVA and IVB osteomyelitis. Adequate debridement, stabilization with external fixation, and staged vancomycin-impregnated cancellous bone grafting were used in all patients. Regular clinical and radiographic follow-ups were conducted.Results Infection control was obtained in all 18 patients with a 100% infection arrest rate. Bone union was achieved in 13 of 18 patients at an average of 5.8 months. Bone union was obtained subsequently in the remaining five patients after closed nailing in four, and plating and bone grafting in one patient. Radiographs showed good consolidation and hypertrophy of grafted bone at an average follow-up of 48 months.Conclusion We conclude that vancomycin-impregnated cancellous bone grafting is a safe method for the treatment of infected tibial nonunion. 相似文献

BackgroudThe aim of this study was to evaluate results of osteoperiosteal decortication and autogenous cancellous bone graft combined with a bridge plating technique in atrophic and oligotrophic femoral and tibial diaphyseal nonunion.MethodsWe retrospectively reviewed 31 patients with atrophic or oligotrophic femoral and tibial diaphyseal nonunion treated with osteoperiosteal decortication and autogenous cancellous bone graft between January 2008 and December 2018. Patients with hypertrophic nonunion, infected nonunion, and nonunion treated with autogenous cancellous bone graft alone were excluded. The nonunion site was exposed by using the Judet technique of osteoperiosteal decortication. Nonunion with a lack of stability was stabilized with a new plate using a bridge plating technique or augmented by supplemental fixation with a plate. Nonunion with malalignment was stabilized with a new plate after deformity correction. Autogenous cancellous bone graft was harvested from the posterior iliac crest and placed within the area of decortication. A basic demographic survey was conducted, and the type of existing implants, mechanical stability of the implants, the type of implants used for stabilization, the operation time, the time to bone union, and postoperative complications were investigated.ResultsThe average follow-up period was 33.3 months (range, 8–108 months). The operation time was 207 minutes (range, 100–351 minutes). All but 1 nonunion (96.7%) were healed at an average of 4.2 months (range, 3–8 months). In 1 patient, bone union failed due to implant loosening with absorbed bone graft, and solid union was achieved by an additional surgery for stable fixation with a new plate, osteoperiosteal decortication, and autogenous cancellous bone graft. There were no other major complications such as neurovascular injuries, infection, loss of fixation, and malunion.ConclusionsOsteoperiosteal decortication and autogenous cancellous bone graft combined with stable fixation by bridge plating showed reliable outcomes in atrophic and oligotrophic diaphyseal nonunion. This treatment modality can be effective for treating atrophic and oligotrophic diaphyseal nonunion because it is very helpful stimulating bone union. 相似文献

The data presented in this article support the view that first saucerizing the infected bone and then grafting give good results. Immediate bone grafting, that is, bone grafting within a few days or weeks of saucerization, will fail when insufficient care has been employed in preparing the area for bone grafting. Using finely divided cancellous bone combined with a suitable fixator is important. Treatment of a nonunion can be successful without bone grafting if, after complete saucerization, stability is achieved by a brace, cast, or external fixator. Failure in all categories of patients is, in the main, due to failure to control the infection or inadequate stabilization. Posterolateral bone grafting may be an excellent alternative and was used in 20 per cent of the patients with tibial nonunion and a substantial loss of tibial shaft. 相似文献

This prospective cohort study compared opening wedge high tibial osteotomy with use of the Puddu plate and the Vitoss synthetic cancellous bone versus closing wedge high tibial osteotomy with use of the AO/ASIF L-plate, focusing on complications (nonunions, infections, loss of correction, reoperations) and patient satisfaction (visual linear analog scale). During a 10-month period, we performed high tibial osteotomy for 40 patients experiencing medial knee osteoarthritis and a varus deformity. The average follow-up was 11 months. The complication rate in patients treated with the opening wedge technique was significantly higher regarding tibial nonunion, loss of correction, and material failure. Patients in the closing wedge group were more satisfied with the postoperative result. This study found that the Puddu plate, despite 6 weeks of non-weight bearing facilitating the osseous consolidation with Vitoss cement, was not able to maintain the correction during the time required for bone healing. 相似文献

Forty-two consecutive patients with chronic osteomyelitis complicating persistent tibial nonunion and chronic osteomyelitis complicating tibial fracture with segmental bone loss were treated from January 1979 through December 1986 using a protocol including either open cancellous bone grafting (Friedlaender-Papineau technique), posterolateral bone grafting (Harmon technique), or local or microvascular soft-tissue transfer before cancellous bone grafting. Each patient had undergone surgical debridement and intravenous antibiotic therapy before inclusion in this study. Patients were classified using a staging system which included consideration of anatomic location of the infection within the bone; extent of bone involvement; quality of soft-tissue envelope and vascular integrity; and generalized host status. The overall success rate for arresting the osteomyelitis and healing the nonunion was 62% (26/42). If the six patients who refused additional bone graft surgery, the one patient who represented poor patient selection, and the patient who refused ankle arthrodesis are eliminated, the success rate for healing of the nonunion and resolving the osteomyelitis in this difficult patient population is: open bone cell graft, 66% (12/18); soft-tissue transfer 87.5%, (7/8); and posterolateral bone grafting, 87.5% (7/8). Use of a standardized classification system allows comparison of treatment results. Adequate debridement is crucial in treating osteomyelitis complicating established long bone fractures and nonunions. Determining the extent of debridement has proven to be the single most difficult aspect technically. Patient selection and pretreatment education are crucial. Caring for these patients is not only labor intensive and demanding of personnel and hospital resources, but demanding of the patients as well. 相似文献

Treatment of tibial defect and bone nonunion with limb shortening with external fixator and reconstituted bone xenograft 总被引:6,自引:0,他引:6
Objective: To explore the effect of external fixator and reconstituted bone xenograft (RBX) in the treatment of tibial bone defect, tibial bone nonunion and congenital pseudarthrosis of the tibia with limb shortening. Methods : Twenty patients ( 13 males and 7 females)with tibial bone defect, tibial bone nonunion or congenital pseudarthrosis of the tibia with limb shortening were treated with external fixation, Two kinds of external fixators were used: a half ring sulcated external fixator used in 13 patients and a combined external fixator in 7 patients.Foot-drop was corrected at the same time with external fixation in 4 patients. The shortened length of the tibia was in the range of 2-9 cm, with an average of 4.8 cm. For bone grafting, RBX was used in 12 patients, autogenous ilium was used in 3 patients and autogenous fibula was implanted as a bone plug into the medullary canal in 1 case,and no bone graft was used in 4 patients. Results: All the 20 patients were followed-up for 8 months to 7 years, averaging 51 months. Satisfactory function of the affected extremities was obtained. All the shortened extremities were lengthened to the expected length. For all the lengthening area and the fracture sites,bone union was obtained at the last. The average healing time of 12 patients treated with RBX was 4.8 months. Conclusions: Both the half ring sulcated external fixator and the combined external fixator have the advantages of small trauma, simple operation, elastic fixation without stress shielding and non-limitation from local soft tissue conditions, and there is satisfactory functional recovery of affected extremities in the treatment of tibial bone defects, tibial bone nonunion and congenital pseudarthrosis of the tibia combined with limb shortening.RBX has good biocompatibility and does not cause immunological rejections. It can also be safely used in treatment of bone nonunion and has reliable effect to promote bone healing. 相似文献

BackgroundThe purpose of this study is to introduce and review the clinical outcomes of a new technique for harvesting autogenous cancellous bone grafts in association with tibial intramedullary (IM) nailing.Materials and methodsWe retrospectively reviewed 21 patients who received autogenous cancellous bone grafts obtained from the entry portal of a tibial IM nail for fracture gaps, malalignment or nonunion in the lower extremities. All patients were scheduled to receive IM nailing or had already received IM nailing for the fixation of an ipsilateral tibia shaft fracture. A total of 33 patients who received only tibial IM nailing were selected as a control group. Through the follow-up, postoperative complications related to the bone harvest were monitored. Further by taking serial X-rays, radiographic changes of the donor site and the knee joint were closely observed. Knee pain (visual analogue scale (VAS)) and function (Lysholm knee score) were compared between the study group and the control group.ResultsAt the last follow-up, the average VAS in the study group was 1.28 (0–5), which was not significantly different from the control group (VAS: 1.36, range 0–7) (P = 0.985). The range of motion of the knee joint was similar in both groups, averaging 130.23° (range: 115–135°) and 131.36° (range: 115–135°), respectively. There was no significant difference in the Lysholm knee score between the study and control groups (P = 0.610). All patients exhibited complete fracture healing at an average of 6 months and no complications associated with the bone donor site were observed.ConclusionsBy using the new technique, autogenous cancellous bone grafting can be performed conveniently and safely to treat fracture gaps, malalignment or nonunion in the lower extremities without additional morbidity at the donor site. 相似文献

Intercalary tibial allografts following tumor resection: the role of fibular centralization 总被引:4,自引:0,他引:4
Options to reconstruct intercalary tibial defects include allografts, vascularized bone transfers, autogenous cortical grafts, endoprostheses, and Ilizarov bone transport. Five patients underwent intercalary bulk allograft reconstruction following en bloc resection of tibial sarcomas. Two patients underwent immediate fibular centralization and iliac crest bone grafting in addition to the allograft. Two patients who underwent fibular centralization during primary reconstruction united uneventfully. The remaining three patients developed nonunion, of which one was successfully salvaged by fibular centralization. A combined allograft transplant and fibular centralization with iliac crest bone grafting is an effective procedure to reconstruct the tibial diaphysis, as well as a salvage procedure for allograft nonunion. 相似文献

The treatment of 25 tibias in 25 patients with posttraumatic chronic osteomyelitis was reviewed. The approaches to soft tissue management fell into three groups: 1) muscle flap coverage; 2) primary closure with suction irrigation; and 3) open cancellous bone grafting. Treatment success was judged by the presence or absence of drainage and the local signs or symptoms of infection, and by the status of the tibial nonunion. Overall, 19 of 25 tibias (76%) had successful treatment. We found flap coverage to have a higher success rate (80%) than either primary closure with suction irrigation (45.5%) or open cancellous bone grafting (40%). These results further attest to the refractory nature of chronic osteomyelitis. 相似文献
