This study demonstrates that harvesting a vascularized fibular graft has a significant number of minor complications. These complications do not result in significant morbidity but could be avoided by other newer methods of managing bony defects and avascular necrosis such as porous bone substitute rods. The purpose of this study was to evaluate functional outcomes of the foot and ankle following vascularized fibula graft harvest, using validated outcome measures. This study agrees with previous reports in that minor complications are commonly associated with free fibula harvest. Functional outcome scores demonstrate significant differences in pain and disability; however, the disability associated with daily activities is small. This is the first study to assess the outcomes of vascularized fibular grafts with validated outcomes measures. It is one of a few studies to assess the outcomes of vascularized fibular grafts on an otherwise normal lower extremity. Twenty-two patients were available for study, with ten attending for examination. All had undergone free fibula transfer for mandibular reconstruction. Functional outcome was assessed using MODEMS (includes SF-36) and Foot Function Index (FFI). A radiographic analysis was performed. All patients had a normal contralateral foot and ankle which was used as a control. Mean follow-up is 3.1 years. Sixty percent of patients were satisfied following surgery. Subjective complaints of weakness, instability and numbness were reported. Minor wound complications were seen in twenty-three percent of patients and clawing of the lesser toes in eighteen percent. No significant difference was seen in the SF-36 categories when compared to population norms. The FFI identified significant differences in Pain and Disability means when compared to the contralateral side. Radiographic analysis failed to demonstrate increased arthritic change or instability. Two patients had undergone further surgery for toe clawing and persistent ankle pain

Vascularised bone grafts have been most commonly applied in reconstructions of the lower extremities. However, the indications for vascularised bone grafts in the upper extremities have now been expanded, as this technique is becoming more widely appreciated. Between 1993 and 2000, 12 patients who had segmental bone defects following trauma of the forearm received vascularised fibular grafts, among them six men and six women. The average age was 39 years (range 16–65 years). The reconstructed sites were the radius in eight patients and the ulna in four. The length of the bone defect ranged from 6 to 13 cm. In four cases the fibular graft was raised as a vascular osteoseptocutaneous fibular graft. For fixation of the grafted fibula, plates were used in ten cases, screws and Kirschner wires in two. In these two cases an external skeletal fixator was used for immobilisation of the extremity. The follow-up period ranged from 93 to 10 months. In 11 patients grafting was successful. There were no instances of fractures of the grafted bone; however, non-union occurred at the proximal site in one case and only one patient required an additional bone graft. No patient showed evidence of resorption of the graft or symptoms related to the donor leg. No recurrence of local infection was encountered in the patients with previous osteomyelitis. The mean period to obtain radiographic bone union was 4.8 months (range 2.5–8 months). With the use of fibular grafts a segment of diaphyseal bone can be transferred that is structurally similar to the radius and ulna and that is of sufficient length for the reconstruction of most skeletal defects in the forearm. A vascularised fibular graft is indicated in patients with intractable non-unions, where conventional bone grafting has failed or for large bone defects (in excess of 6 cm) in the radius or ulna

Introduction and Aims: The treatment of bone defects secondary to congenital pseudoarthrosis of the tibia, infections and tumors is problematic. The vascularised fibular graft has been used for many years as a way to improve blood supply and successfully achieve union. Lengthening the limb prior to grafting can improve outcomes. Method: Forty-one patients with major bone defects secondary to tumor resections, infections and congenital pseudoarthroses had reconstruction with a vascularised fibular graft. Of these, 10 patients had limb length discrepancies, which were treated by application of an external fixater for lengthening through the bone gap. Following restoration of length with an external fixater, a vascularised fibular graft was inserted to bridge the bone defect. The external fixater was not removed until union of the graft to the host bone and initial hypertrophy occurred. Results: The 10 patients (five males and five females) were aged 2.5 to 14.5 years (mean 7.6 years). The affected bones included eight tibias, one humerus and one ulna. The limb length discrepancies ranged from three to 20cm (mean 6.44cm). The duration of lengthening prior to definitive vascularised fibular graft ranged between one to 15 weeks (mean seven weeks) in nine patients. In the patient with a discrepancy of 20cm, lengthening spanned 52 weeks. At the time of the definitive vascularised fibular graft procedure, the fixater was partially disassembled to facilitate surgery and microvascular anastomosis. The frame was then reassembled and used as the fixation device to protect the graft. The fixater was removed from seven to 24 weeks (mean 16 weeks) after definitive surgery. There were no complications during the lengthening process. However, two patients experienced non-unions, which were successfully treated by autologous bone grafts. One patient had a fracture of the vascularosed fibular graft, which healed uneventfully. Conclusion: A staged approach to reconstruction of major long bone deficiencies leads to a better outcome than insertion of vascularised fibular grafts without addressing the limb length discrepancy. In this type of procedure, the patients not only bridged their bone defect, but achieved limb length equality as well

Introduction: Osteochondral reconstruction following tumour resections has a high complication rate. We hypothesized that the vascularised fibular graft as a supplement to the allograft reconstruction following tumour resections would provide a biological solution. Purpose of the study: A prospective study of the results of patients receiving large fragment allografts and vascularised fibular grafts following tumour resections around the hip and the knee. Patients and methods: 18 patients underwent resection of primary malignant bone tumors followed by reconstruction with large fragment allograft and vascularised fibular graft. 8 patients underwent resection arthrodesis of the hip, six underwent resection arthrodesis of the knee and five underwent intercalary resections around the knee followed by a large fragment allograft and vascularised fibular graft reconstruction to span the gap left by resection. The patients were assessed clinically (MSTS scoring system) and radiologically at regular intervals. Results: There were 14 males and 4 females, with a mean age of 26 years (12–70). Mean follow-up was 65 months (8–144). Five patients died of metastatic disease but without local recurrence. In six of the patients with resection arthrodesis of the hip, there was evidence of fracture of the allograft but without the failure of the construct. One fibula fractured but eventually healed uneventfully. There were no cases of non-union in cases of intercalary resections. All the patients scored good or excellent in the MSTS scoring system. Discussion: Our experience clearly indicates that tumour resection followed by reconstruction with large fragment allograft and vascularised fibular graft is a useful limb salvage procedure providing a biological long-term solution with superior results when compared to prosthetic reconstruction

This is a prospective study assessing the results of patients receiving large fragment allograft and a vascularised fibular graft following primary malignant tumour resections around the hip and the knee. 18 patients underwent tumor resection followed by reconstruction with large fragment allograft and vascularised fibular graft. Eight patients underwent resection arthrodesis of the hip, four underwent resection arthrodesis of the knee and six underwent intercalary resections. Following tumour resection with adequate margins, an appropriate sized allograft fragment was internally fixed with either a plate or an intramedullary nail. A vascularised fibular graft was used to span the gap between the remaining host bones. Osteosarcoma was the commonest diagnosis. The patients were clinically assessed by MSTS functional scoring system and radiologically assessed at regular intervals. The mean age was 26 years (range12–70) and majority of the patients was men. 11 patients received preoperative chemotherapy. Mean follow-up was 85 months (range 8–153). Six patients have died of metastatic disease at a mean of 33 months. Complications included local recurrence in two, deep infection in one and stress fracture of the fibula in two cases. One patient with local recurrence and the other with deep infection underwent an amputation. Majority of the patients had good or excellent MSTS scores at final follow-up and 75% of the patients are engaged in physically active occupations. Graft hypertrophy was evident in majority of the patients. Our experience clearly indicates that reconstruction with large fragment allograft and vascularised fibular graft is a useful limb salvage procedure with the fibula hypertrophying slowly with time. The eventual fracture of the allograft or failure of the allograft-plate composite is to be expected but is not deleterious due to the physiological response of the vascularised fibula to the weight bearing stresses over time. We feel that this biological solution is likely to demonstrate superior long-term results compared to a prosthetic reconstruction

We present a case of a 19-year-old white female patient with neurofibromatosis type I who, 10 years ago, underwent free vascularized fibular grafting for isolated congenital pseudarthrosis of her left radius. An external fixator was applied for gradual distraction and correction of the deformity of the pseudarthrosic site for five weeks. Wide resection of pseudarthrosis with surrounding fibrotic and thick scar tissue and bridging of the gap with a free vascularized fibular graft followed. Four months postoperatively, union was established in both graft ends. At the last follow-up, 10 years postoperatively, the patient has excellent function with full wrist flexion-extension and forearm pronation-supination. Free vascularized fibula transfer is considered the treatment of choice for congenital radial pseudarthrosis. It allows complete excision of the pathologic tissue and covering of the gap in one operation. Due to the vascularity of the free vascularized fibular graft both sides of fibula unite easily with no additional intervention

Aims: The purpose of this study is to to assess the surgical results, complications, and long-term results of vascularized fibula in the treatment of congenital pseudarthrosis of the tibia. Methods: Seven patients who had congenital pseudarthrosis of the tibia were treated consecutively at our clinic between 1992 and 2000 with free vascularized fibular graft. There were four females and three males. The mean age at the time of operation averaged 6.5 years (range 1–12 years). Four left tibias and 3 right tibias were involved. Stability was maintained with internal fixation in four patients, external fixation in two patients and intramedullary pin in one patient. Results: The average follow-up was 2.6 years (range 6 months to 8 years). In five patients, both ends of the graft healed primarily within 2.7 months (range 1.5 to 3 months), and hypertrophy of the fibular graft occurred rapidly with a well-formed medullary canal. In one patient the distal junction did not unite and although required three subsequent operations still not healed. Stress fracture occurred in one patient underwent four additional operations before union achieved. Conclusions: Despiting the continuing problems and the relatively high complication rate, the ultimate results with free vascularized fibula transplant are generally good specially as compared with published series in whom conventional grafting techniques had failed. However, even achieving union of pseudarthrosis is not enough for the resolution of this disease and is only half of the problem; the other half is to maintaining

In order to investigate the efficacy of free vascularised fibular graft (VFG) after bone intercalary tumour resection in tibia, we present our results with a minimum follow-up of 2 years. From 1988 to 2001, 47 patients affected by high-grade tibial sarcoma in 31 cases (66%), and low-grade diesease in 16 cases (34%) were treated in our department. Average age was 19 years (range 5–60 years), with a male/female ratio of 1.35. The average length of tibial resection was 15 cm, while the average length of the fibular graft was 19 cm. In 11 cases (21%) VFG was assembled alone, while in 36 cases (79%) a massive bone allograft was associated to the fibula. Three patients developed a deep infection, treated by amputation in two cases and by graft removal and an Ilizarov device in one case. Minor complications occurred in 28 cases (55%) (stress fractures, wound slough, osteosynthesis breakage), all healed by minor surgery or conservative treatment. At an average follow-up of 108 months (range 24 to 185 months), four patients had died of disease and three were lost to follow-up. Regarding the overall results, the combined group of fibula plus massive allograft showed to be more effective than the group of fibula alone in terms of early weight bearing (6 versus 12 months), while VFG showed intrinsic efficacy in achieving early bony fusion at the osteotomy lines and hypertrophy of the graft in both groups. Furthermore, using the combined assembly the articular surface could be spared in all the trans-epiphyseal resections, while VFG alone appeared to be electively indicated for infected or irradiated fields. In conclusion, despite the demanding surgical technique, VFG appears to be a long-lasting and definitive biological reconstruction procedure after intercalary tibial resection

Introduction:. The anterior column of the spine is often destroyed by trauma or disease. It is reconstructed by using autograft, allograft, or synthetic cages. The fibula strut graft provides good strength, incorporates quickly and has less risk of disease transmission, which is a big advantage in communities with high incidence of HIV. Various authors cite that its major drawback is the size of its foot print. We could not find any literature that measures its size. We undertook a study to measure the size of the footprint of the fibular in relation to the surface area of the endplate. The clinical relevance is that it may guide the surgeon in deciding how many struts of fibular are required in reconstructing the anterior column, and also quantifies the statement that the fibular strut has a small footprint. Material and Method:. CT angiograms are done frequently for peripheral vascular diseases. These angiograms also show CT scans of the lumbar and thoracic vertebrae, and fibulae of the same patient. We retrospectively examined the first 35 scans done during the year 2012 at Steve Biko Academic Hospital. From the CT we measured the surface area of the endplate of the vertebral bodies T6, 8, 12, L2, and the surface area of the cut surface of the proximal, middle and distal thirds of the fibular, all in square millimetres. We then compared the areas of the vertebral measurements to the area of the fibular measurements. Results:. The middle third of the fibular had the biggest cross sectional surface area. This fact, together with anatomical features of the fibula, explains why the middle part of the fibular is the preferred graft donor site. The ratio of the fibular surface area to that of the vertebral endplate is 1:3–6. It is difficult to advise in a biological system how many struts are required, as compared to a mechanical system. However these ratios suggest that more than one fibular strut graft is required to reconstruct the anterior column. Conclusion:. This is the first time to our knowledge that the surface area of the fibular graft is quantified against the vertebral end plate surface area. The study shows that at least 2 fibula struts are required to reconstruct the thoracic and lumbar anterior columns

Introduction: It is very important to evaluate the healing process in the femoral head after free vascularized fibular graft (VFG) in osteonecrosis of the femoral head (ONFH). Bone scintigraphy combined with a pinhole collimator, which is simple and not expensive, is used for very high resolution images of small organs, such as thyroid and certain skeletal regions. The purpose of this study was to assess the changes using pinhole bone scintigraphy in ONFH after VFG. Materials and Methods: Changes of Tc-99m-HDP pinhole bone scintigraphy were analyzed in 22 cases of ONFH which were treated with VFG and had satisfactory results in patient evaluations at least 2 years after surgery. Harris Hip Scores were 90 points or more; and femoral head collapse was less than 2 mm. Results: The results were: (1) At 1 week, the pinhole image showed no significant change in cold area but two linear RI uptakes corresponding to the fibular graft were noted. (2) At 3 months, localized hot uptakes just above the tip of the graft were observed in 17 cases (77.2%), and diffuse increased uptake surrounding the cold area were observed. (3) At 6 months, localized hot uptake were increased in size and replaced cold areas and delineated the shape of the superolateral aspect of the femoral head. (4) At 1 year, increased RI uptake of the superolateral aspect of the femoral head expanded medially in all cases. (5) After 2 years, cold areas faded away in 18 cases (81.8%). Discussion: In conclusion, the authors believe that the Tc-99m-HDP pinhole bone scintigraphy is an excellent method to delineate the healing process in ONFH after VFG

Fifteen patients (11 males, 4 females) with a median age of 16 years (range, 7–25) were treated in our centre by intra-articular resection of the proximal femur, and hip arthrodesis using a vascularized fibular graft. Eight patients had Ewing’s sarcoma, 5 osteogenic sarcoma, and 2 chondrosarcoma. After a mean follow up of 58.2 months, 13 patients were alive with no evidence of disease. All fibular grafts united at a mean time of 7.6 months (range, 7–9 months). Four patients had stress fractures of the vascularized fibular graft, all healed after a mean period of 6.5 weeks. Failure of the fixation system occurred in two patients. Deep infection developed in one case which necessitated plate removal. Three of these patients with complications underwent a second procedure, giving a re-operation rate of 20%. The mean MSTS functional score was 85.9% at the time of the latest follow-up. We conclude that hip arthrodesis using a vascularized fibular graft is a viable alternative to endoprosthetic replacement after proximal femoral resections. It should be considered as an effective and durable reconstructive technique in young patients with high physical demands

We are presenting the outcome of a young adult with extensive epithelioid hemangioendothelioma of the femur treated with wide excision and vascularised fibular graft. An 18-year-old builder was referred with an aggressive primary bone tumor of the right femur. Initial staging showed no evidence of distant disease but tumor confined to a 26.5cm diaphyseal segment of the femoral shaft. The patient’s pre-operative Oxford knee score was 28 and the AKSS scores were 74 (observational) and 65 (functional). True cut open biopsy confirmed low grade angiosarcoma. The patient underwent a wide excision of the lesion through a lateral approach leaving a generous cuff of bone and muscle tissue around the tumor. Clear resection margins were assessed intraoperatively. Histologically, the tumor was found to be epithelioid hemangioendothelioma. The 29.5cm defect was filled with a vascularised bone graft of the ipsilateral fibula. The graft was secured with a 22-hole DCS bridging plate and screws at both ends. Intraoperative knee range of motion was from 0 to 125 degrees without recurvatum and graft movement. The patient had an unremarkable recovery. At the latest follow-up, one year after his operation, the patient had made an excellent functional recovery with non-symptomatic full weight bearing and had also returned to his work as a builder. He demonstrated a knee range of motion of 0 to 115 with a slight genu varum. The patient’s post-operative Oxford knee score was 40 and the AKSS scores were 70 (observational) and 90 (functional). Radiographs showed excellent union at the distal aspect of the graft and a healing stress fracture of the fibula graft at the proximal aspect. Vascularized fibular graft with plating is a safe reconstruction limb salvage option for defects of long bones after tumor resection

Aim. To compare the functional outcome of proximal femoral reconstruction using endoprosthetic replacement and hip arthrodesis using a vascularised fibular graft. Material and Methods. The study included thirty-five patients who had proximal femoral reconstruction following resection of a malignant bone tumour. Patients were divided into 2 groups according to the reconstructive modality used. Group 1 (15 patients) reconstructed by hip arthrodesis using a vascularised fibular graft. Group 2 (20 patients) reconstructed by endoprosthesis. The mean age of group I was 14.9 years (range, 7-25). 8 patients had Ewing's sarcoma, 5 osteogenic sarcoma, and 2 chondrosarcoma. In group 2, the mean age was 35 years (range, 14-61). Eight patients had osteogenic sarcoma, 2 chondrosarcoma, 2 Ewing's sarcoma, 1 lymphoma, 1 MFH, 1 synovial sarcoma, 1 parosteal osteosarcoma, and 4 metastatic carcinomas. Results. In group 1 failure of the fixation occurred in two patients, and deep infection developed in one patient. These patients were managed with revision of internal fixation and debridement respectively. The mean MSTS functional score was 87% (range 70 – 96%) at the time of the latest follow-up (mean = 64 months). The average limb length discrepancy was 2 cm (range 1 to 4). In group 2, two patients developed deep infection, one patient had a dislocation, and one had loosening of the implant with a re-operation rate of 20%. After a mean follow up of 49.1 months, the mean MSTS functional score was 79% (range 60 – 93%). Conclusion. The functional outcome of hip arthrodesis using a vascularized fibular graft is comparable to endoprosthetic replacement after proximal femoral resections. It should be considered as a durable reconstructive modality in children and young active patients with long life expectancy

For decades the treatment of chronic posttraumatic osteomyelitis associated with bone exposure has been one of the most serious problems in the field of orthopedic surgery. “Sterilization” of the osteomyelitic site, that is radical debridement of all infected tissue, is the basic requirement of the treatment; in the past, the remaining defect of the debrided area was closed with skin grafts, which were removed in a further stage, when the infection was ceased; then the defect was filled with muscle flap and bone graft of various types. Both soft tissue and osseous reconstruction took a relatively long period of time requiring several-stage treatment. We performed a retrospective study on 9 patients treated for chronic osteomyelitis of the upper limb (6 forearm – 3 arm) by means of free fibula vascularized bone graft, between 1992 and 2003 (7 male 2 female). All patients had been more than 2 previous surgical attempt with conventional treatment (sterilization and bone graft). In most of them (7 cases) a two-stage treatment was performed (resection and sterilization, eventually with muscle transfer, in the first stage and bone transfer in the second one); in other 3 cases a one-stage treatment was performed. Two cases required a composite tissue transfer with a skin pad to cover the exposure. The length of bone defect after extensive resection of necrotic bone from septic pseudoarthrosis ranged from 5 cm to 12 cm. In all cases there was no evidence of infection recurrence in the follow-up period. The mean period to obtain radiographic bone union was 4.1 months (range 2.5–6 months). In 2 cases secondary procedures have been carried out due to an aseptic non union in one site of synthesis (cruentation and compression plate). Functional results were always satisfactory although in the forearm a complete range of motion has never been achieved (plurioperated patients with DRUJ problems). Fibular grafts allow the use of a segment of diaphyseal bone which is structurally similar to the radius, ulna and humerus of sufficient length to reconstruct most skeletal defects. The vascularized fibular graft is indicated in patients where conventional bone grafting has failed or large bone defects, exceeding 5 cm, are observed. The application of microsurgical fibular transfers for reconstruction of the extremities allows repair of bone and soft-tissue defects when shortening is not possible with good functional results

Aims: Free vascularized fibular graft for osteonecrosis of the femoral head is a well established procedure based on the assumption that the graft will provide mechanical support, blood supply to the osteonecrotic head and to introduce mesenchymal stem cells into the affected area of the femoral head. Methods: We reviewed 25 cases to delineate the pathological features of femoral heads with AVN treated by vascularised fibular grafts which were retrieved at revision surgery when the construct was deemed clinically to have failed. Results: Review of the patients’ records disclosed that 60.8% were on steroid therapy when the AVN was diagnosed. The recorded time from first symptoms of failure to conversion to total hip arthroplasty was an average of 55 months. The length of the graft was divided into three zones : zone 3 the femoral neck; zone 2 the lower femoral head or “metaphysis”; zone 1 the more apical or epiphyseal component of the femoral head. The intention was to follow the vascularization of the pedicle and the changes in the three diverse areas of the specimen. The graft showed incorporation with the host bone. In the pedicle there was preservation of vascular patency and tissue viability. Conclusion: However, this healing process involved a slow reparative resorptive activity which undermined the joint surface. This could suggest that non-resorbable materials in place of tissue grafts can be expected to avoid the negative effect of creeping substitution as an undermining force in the repair and revascularisation of the necrotic area in the head

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

The purpose of this study was to compare the clinical and radiological findings in patients with avascular necrosis of the femoral head after management with vascularized fibular graft (VFG) compared to porous tantalum implant. The study included 60 hips in 50 patients, who were followed prospectively for 2–4 years. 28 patients (30 hips) were treated with VFG and 22 patients (30 hips) were treated with a porous tantalum implant. The two patient groups were matched for age, gender, etiology, pre-operative stage and Harris Hip Score (HHS). Of the VFG group, 14 hips were stage II and 16 were stage III, while of the tantalum group, 1 hip was stage I, 11 hips were stage II and 18 hips were stage III, according to Steinberg classification system. Mean operative time was 3 hours for VFG and 30 min for porous tantalum. At final follow-up, there was no significant statistical difference in the radiological stage (p=0.246), and radiological progression of the disease (p=0.329) was observed between these two groups. Using HHS, the mean clinical results improved in the VFG group from 61 points preoperatively to 90 points at final follow-up, while in tantalum group HHS improved from 63 to 81 points (p=0.022). Three hips from each group underwent total hip arthroplasty. The results of the present study suggest that although the management of AVN with VFG appears to show better results compared to the use of porous tantalum using clinical evaluation Methods: (eg HHS), further controlled studies with larger patient groups and longer follow-up are required

We evaluated the clinical, radiographic, and functional outcome of uncemented total hip arthroplasty (THA) following vascularized fibular grafting for avascular necrosis (AVN) of the femoral head. A group of twenty-two patients who had been converted from a vascularized fibular graft to THA was compared to a similar group of twenty-two patients who had received a THA with no prior graft. The graft group was found to have worse outcomes than the control group as measured by SF-36, and WOMAC scores, as well as a hip score. These results show that vascularized fibular grafting complicates future THA. The Purpose of this study was to evaluate the clinical, radiographic, and functional outcome of uncemented total hip arthroplasty (THA) following vascularized fibular grafting for avascular necrosis (AVN) of the femoral head. These results indicate that functional and clinical outcome following post-graft THA is worse than outcome following THA performed as a primary intervention. Judicious use of the vascularized fibular graft procedure is critical in order to minimize the number of graft failures and avoid the negative outcomes associated with THA after failed vascularized fibular grafting. Twenty-six hips in twenty-two patients who had a THA following a failed vascularized fibular graft were compared to a group of twenty-three hips in twenty-two age and sex-matched patients who had received a THA with no prior graft (combined mean age: 39.0 yrs). Primary outcome measures included the SF-36 (patient-based general health assessment – total score and physical sub-component) and WOMAC (patient-based arthritis specific score) scores at matched follow up times (mean: 6.2years, range: two to fourteen years). An objective hip score was also used, as were several radiographic variables. The post-graft group had lower SF-36 final scores (p< 0.006), lower SF-36: physical function scores (p< 0.001), and lower WOMAC scores (p< 0.045) than the control group. Post-graft THA was complicated by longer operative time (p< 0.025) and greater subsidence of the femoral prosthesis (p< 0.004) compared to controls. Additionally, the post-graft group had worse hip score values (p< 0.05) than controls. Vascularized fibular grafting is a commonly used procedure to cure or delay progression of AVN in the hip. Currently this procedure is used for young (< 40 years) patients with hip AVN who are in an early, pre-collapse stage of the disease. Although the efficacy of vascularized fibular grafting has been proven, up to 29% of grafts fail at five years and need to be converted to THA (Urbaniak et al., 1995). This study shows that THA after failed vascularized fibular grafting has a worse outcome than THA as a primary intervention. Therefore judicious use of the graft procedure is critical in order to minimize the number of graft failures and avoid the negative outcomes associated with it

Any intervention for limb with compromised bone and soft tissue in paediatric age group is often studded with complications of flare of infection, wound breakdown, delayed healing or failure of grafting. We report our experience with managing 8 such cases with periosteal sleeve taken from tibia along with fibular grafting. The lesion was gap non-union following bone sequestration in 7 cases (2 proximal humerus; 4 femur and one metacarpal) and one case tibia vara in post osteomyelitic tibia. The infective lesions were silent for minimum of 1 year before this procedure. The periosteal sleeve was taken from proximal tibia and fibular graft was also procured from same leg. Following freshening of bone ends, the fibular graft was applied at non-union/osteotomy site and enclosed in the freshly harvested periosteal sleeve. The limb was protected in plaster cast for 6 weeks and assessed clinicoradiologically at 3 and 6 weeks intervals. Uneventful union followed in 7 cases in 6 weeks time. In one case of proximal humerus, the osteosynthesis attempt failed. The periosteal and fibular graft site posed minimal morbidity for the child. Conclusions. Periosteal sleeve and fibular grafting offers a promising alternative for interventions in post osteomyelitic bone with compromised soft tissue

Aim. The number of operatively treated clavicle fractures has increased over the past decades. Consequently, this has led to an increase in secondary procedures required to treat complications such as fracture-related infection (FRI). The primary objective of this study was to assess the clinical and functional outcome of patients treated for FRI of the clavicle. The secondary objectives were to evaluate the healthcare costs and propose a standardized protocol for the surgical management of this complication. Method. All patients with a clavicle fracture who underwent open reduction and internal fixation (ORIF) between 1 January 2015 and 1 March 2022 were retrospectively evaluated. This study included patients with an FRI who were diagnosed and treated according to the recommendations of a multidisciplinary team at the University Hospitals Leuven, Belgium. Results. We evaluated 626 patients with 630 clavicle fractures who underwent ORIF. In total, 28 patients were diagnosed with an FRI. Of these, eight (29%) underwent definitive implant removal, five (18%) underwent debridement, antimicrobial treatment and implant retention, and fourteen patients (50%) had their implant exchanged in either a single-stage procedure, a two-stage procedure or after multiple revisions. One patient (3.6%) underwent resection of the clavicle. Twelve patients (43%) underwent autologous bone grafting (tricortical iliac crest bone graft (n=6), free vascularized fibular graft (n=5), cancellous bone graft (n=1)) to reconstruct the bone defect. The median follow-up was 32.3 (P. 25. -P. 75. : 23.9–51.1) months. Two patients (7.1%) experienced a recurrence of infection. The functional outcome was satisfactory, with 26 out of 28 patients (93%) having full range of motion. The median healthcare cost was € 11.506 (P. 25. -P. 75. : € 7.953–23.798) per patient. Conclusion. FRI is a serious complication that can occur after the surgical treatment of clavicle fractures. Overall, the outcome of patients treated for FRI of the clavicle is good, when management of this complication is performed by using a multidisciplinary team approach. The median healthcare costs of these patients are up to 3.5 times higher compared to non-infected operatively treated clavicle fractures. Expert opinion considers factors such as the size of the bone defect, the condition of the soft tissue, and patient demand to guide surgical decision making
