Introduction and Objective. Lower limb fractures are amongst the most common surgically managed orthopaedic injuries, with open reduction and internal fixation (ORIF) as the conventional method of treatment of the fibula. In recent years, dedicated intramedullary implants have emerged for fibula fixation in tandem with the move towards minimally invasive surgery in high-risk patients. This is the largest multicentre review to date with the aim of establishing the clinical outcomes following intramedullary nail (IMN) fixation of the fibula and to identify the absolute indication for fibula IMN fixation. Materials and Methods. A retrospective study of adult patients in all UK hospitals, who underwent fibula nail fixation between 01/01/2018 and 31/10/2020 was performed. Primary outcome measures included time to union, infection rate, other post-operative complications associated with the fixation and length of hospital stay. The secondary outcome measure was to identify the indication for fibula nailing. Data tabulation was performed using Microsoft Excel and analysis was performed using SPSS Version 23 (SPSS Statistics). Results. 2 Major Trauma Centres (MTCs) and 9 Trauma Units (TUs) were eligible for inclusion. 102 patients were included and 91% were classified as ankle fractures of 68% (n=69) were Weber B, 24% (n=24) Weber C and 8% (n=9) were either distal tibial fractures with an associated fibula fracture or pilon fractures. The mean age was 64 years of which 45 were male patients and 57 were female. The average BMI was 30.03kg/m. 2. and 44% of patients were ASA 3. 74% of patients had poor pre-op skin condition including swelling and open wounds. The calculated infection rate for fibula nail was 4.9% and metal-work complication rate was 4.9%. The average time to union was 13 weeks and length of inpatient stay was 15 days (SD +/− 12 days). Conclusions. MEFNO has demonstrated that fibula nail is an ideal implant in patients who have a physiologically higher risk of surgery, poor skin condition and a complex fracture pattern. The time to union, complication and infection risks are lower than that reported in literature for ankle ORIFs

Aims. Congenital pseudarthrosis of the tibia (CPT) has traditionally been a difficult condition to treat, with high complication rates, including nonunion, refractures, malalignment, and leg length discrepancy. Surgical approaches to treatment of CPT include intramedullary rodding, external fixation, combined intramedullary rodding and external fixation, vascularized fibular graft, and most recently cross-union. The current study aims to compare the outcomes and complication rates of cross-union versus other surgical approaches as an index surgery for the management of CPT. Our hypothesis was that a good index surgery for CPT achieves union and minimizes complications such as refractures and limb length discrepancy. Methods. A multicentre study was conducted involving two institutions in Singapore and China. All patients with CPT who were surgically managed between January 2009 and December 2021 were included. The patients were divided based on their index surgery. Group 1 included patients who underwent excision of hamartoma, cross-union of the tibia and fibula, autogenic iliac bone grafting, and internal fixation for their index surgery. Group 2 included patients who underwent all other surgical procedures for their index surgery, including excision of hamartoma, intramedullary rodding, and/or external fixation, without cross-union of the tibia and fibula. Comparisons of the rates of union, refracture, limb length discrepancy, reoperations, and other complications were performed between the two groups. Results. A total of 36 patients were included in the study. Group 1 comprised 13 patients, while Group 2 comprised 23 patients. The mean age at index surgery was four years (1 to 13). The mean duration of follow-up was 4.85 years (1.75 to 14). All patients in Group 1 achieved bony union at a mean of three months (1.5 to 4), but ten of 23 patients in Group 2 had nonunion of the pseudarthrosis (p = 0.006). None of the patients in Group 1 had a refracture, while seven of 13 patients who achieved bony union in Group 2 suffered a refracture (p = 0.005). None of the patients in Group 1 had a limb length discrepancy of more than 2 cm, while ten of 23 patients in Group 2 have a limb length discrepancy of more than 2 cm (p = 0.006). In Group 1, four of 13 patients had a complication, while 16 of 23 patients in Group 2 had a complication (p = 0.004). Excluding removal of implants, four of 13 patients in Group 1 had to undergo additional surgery, while 18 of 23 patients in Group 2 had to undergo additional surgery following the index surgery (p = 0.011). Conclusion. A good index surgery of excision of hamartoma, cross-union of the tibia and fibula, autogenic iliac bone grafting, and internal fixation for CPT achieves union and minimizes complications such as refractures, limb length discrepancy, and need for additional surgeries

Introduction. Fibula shortening with an intact anterior tibiofibular ligament (ATFL) and medial ligament instability causes lateral translation of the talus. Our hypothesis was that the interaction of the AITFL tubercle of the fibular with the tibial incisura would propagate lateral translation due to the size differential. Aim. To assess what degree of shortening of the fibular would cause the lateral translation of the talus. Methodology. Twelve cadaveric ankle specimens were dissected removing all soft tissue except for ligaments. They were fixed on a specially-designed platform within an augmented ankle cage allowing tibial fixation and free movement of the talus. The fibula was progressively shortened in 5mm increments until complete ankle dislocation. The medial clear space was measured with each increment of shortening. Results. The larger AITFL tubercle interaction with the smaller tibial incisura caused a significant increase in lateral translation of the talus. This occurred in most ankles between 5–10mm of fibular shortening. The medial clear space widened following 5mm of shortening in 5 specimens (mean=2.0725, SD=±2.5338). All 12 specimens experienced widening by 10mm fibula shortening (Mean=7.2133mm, SD=±2.2061). All specimens reached complete dislocation by 35mm fibula shortening. Results of ANOVA analysis found the data statistically significant (p<0.0001). Conclusion. This study shows that shortening of the fibula causes a significant lateral translation of the talus provided the ATFL remains intact. Furthermore, the interaction of the fibula notch with the ATFL tubercle of the tibia appears to cause a disproportionate widening of the medial clear space due to its differential in size. Knowledge of the extent of fibula shortening can guide further intervention when presented with a patient experiencing medial clear space widening following treatment of an ankle fracture

Introduction. The use of vascularised fibula grafts is an accepted method for reconstructing the distal femur following resection of malignant childhood tumours. Limitations relate to the mismatch of the cross-sectional area of the transplanted fibula graft and thel ocal bone, instability of the construct and union difficulties. We present midterm results of a unique staged technique—an immediate defect reconstruction using a double-barrel vascularised fibula graft set in in A-frame configuration and a subsequent intramedullary femoral lengthening. Materials & Methods. We retrospectively included 10 patients (mean age 10 y)with an osteosarcoma of the distal femur, who were treated ac-cording to the above-mentioned surgical technique. All patients were evaluated with regards to consolidation of the transplanted grafts, hypertrophy at the graft-host junctions, leg length discrepancies, lengthening indices, complications as well as functional outcome. Results. The mean defect size after tumour resection was 14.5 cm, the mean length of the harvested fibula graft 22 cm, resulting in a mean (acute) shortening of 4.7 cm (in 8 patients). Consolidation was achieved in all cases, 4 patients required supplementary bone grafting. Hypertrophy at the graft-host junctions was observed in78% of the evaluable junctions. In total 11 intramedullary lengthening procedures in 9 patients had been performed at the last follow up. The mean Muskuloskeletal Society Rating Scale(MSTS) score of the evaluable 9 patients was 85% (57% to 100%)with good or excellent results in 7 patients. Conclusions. A-frame vascularised fibula reconstructions showed encouraging results with respect to defect reconstruction, length as well as function and should therefore be considered a valuable option for reconstruction of the distal femur after osteosarcoma resection. The surgical implementation is demanding though, which is emphasized by the considerable high number of com-plications requiring surgical intervention, even though most were not serious

Introduction. Reconstruction of large defect of tibia following infection is considered as one of the most difficult problem facing the orthopaedic surgeon. Amputation with modern prosthetic fitting is a salvage procedure to treat big defects, which gives a functional result with unpredictable psychological impact. Materials & Methods. Between January 2000 and January 2021, 56 patients (30 males and 26 females) with big defects following infection and post traumatic injury of the tibia were treated. The mean age of the patients at the time of surgery was 20.5 years (4–24 years). The fibula was mobilized medially to fill the defect and was fixed with Ilizarov fixator. The average size of the defects reconstructed was 18.5 cm (17–20 cm). Results. The average time for complete union was 8.6 months (range, 5–9 months). At final follow-up all patients had fully united. We found leg length discrepancy in 52 patients and that was corrected by re-lengthening of the solid new regenerate bone. Conclusions. The Ilizarov method has been shown to be an effective method of treating Tibialization of fibula for reconstruction of big tibial defects

Introduction. The purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration. Materials & Methods. Sixteen patients in Northern Ireland had free vascularised fibula grafting. Inclusion criteria included grafting to humeral defects secondary to osteomyelitis. Six patients were included in this study. Patients were contacted to complete DASH (Disabilities of the Arm, Shoulder and Hand) questionnaires as our primary outcome measure. Secondary outcome measures included radiological evaluation of osteointegration and associated operative complications. Complications were assessed via review of Electronic Care Record outpatient and in-patient documents

Background. In fixation of the fibula in ankle fractures, AO advocate using a lag screw and one-third tubular neutralisation plate for simple patterns. Where a lag screw cannot be placed, bridging fixation is required. A local pilot service evaluation previously identified variance in use of locking plates in all patterns with significant cost implications. The FAIR study aimed to evaluate current practice and implant use across the United Kingdom (UK) and review outcomes and complication rates between different fibula fixation methods. Method. The study was supported by CORNET, the North East trainee research collaborative, and BOTA. Data was collected using REDCap from 22 centres in the UK retrospectively for a one-year period between 1. st. January 2019 and 31. st. December 2019 on injury mechanism, fracture characteristics, comorbidities, fixation and complications. Follow-up data was collected to at least two-years from the time surgery. Results. 1448 ankle fractures which involved fixation of the fibula were recorded; one-third tubular plate was used in 866 (59.8%) cases, a locking plate in 463 (32.0%) cases and other methods in 119 (8.2%) cases. There was significant difference between centres (p<0.001) in implant type used. Other factors associated with implant type were age, diabetes, osteoporosis, open fractures, fracture pattern and the presence of comminution. Incidence of lateral wound breakdown was higher in locking plates than one-third tubular plates (p<0.05). There was no significant difference in infection, non-union, fixation failure or removal of metalware. Conclusion. There is significant variation in practice in the UK in implant use for fixation of the fibula in ankle fractures. Potentially unnecessary use of locking plates, where a one-third tubular shows equivalent outcomes, incurs additional cost and may increase the risk of lateral wound breakdown. We would encourage surgeons with high locking plate usage to evaluate their own unit's practice against this data

The aim of this study was to assess the incidence of fibula non-union in patients undergoing distraction osteogenesis, and the incidence of symptoms following this. A consecutive series of 58 patients undergoing distraction osteogenesis at a tertiary centre under a single surgeon were included. Data was collected prospectively. Plain radiographs were reviewed retrospectively by a blinded reviewer. Union was defined as the presence of bridging callous on two views. There were 58 distraction procedures performed. The mean age was 37.2 years (range 16.0 to 80.6). There were 36 males and 22 females. The mean follow-up was 23.4 months (4–70 months). 9 (15.5%) went onto non-union at frame removal. 3 (33.3%) of the 9 fibulas that did not unite developed symptoms. 2 (66.7%) of these required surgery in the form of fibula plating. Both of these patient's symptoms resolved following surgery. 3 (33.3%) of the 9 non-united fibulas also had tibial non-union compared to 1 of the 49 where the fibula united. There was no association between location of fibula osteotomy and development of non-union. 35 fibula osteotomies were performed in the third quarter. Of the fibulas that united, the mean fibula lengthening was 9.25 mm (range 1.2–27.8 mm). In the fibulas that went onto non-union the mean lengthening was 23.66 mm (range 5.1–51.5 mm) (P = 0.004). 54 (93.1%) of the tibias united following osteotomy and distraction, whilst 4 (6.9%) went onto non-union requiring operative treatment. Of the 4 tibias that did not unite, 3 (75%) also had fibula non-union (P = 0.01). Fibula non-union is a relatively common complication following osteotomy in distraction osteogenesis. The length of fibula distraction and tibia non-union are significant risk factors for the development of a fibula non-union. We recommend surgical intervention for those patients who have symptomatic fibula non-unions

Introduction and Aim: This project reports on patients treated with malignant fibula pathology at the London Bone Tumor Service with the aim of reporting on the prognosis for such patients. Method and Results: Over a 15-year period, The London Bone Tumor Service has treated 39 patients with malignant fibula pathology: Osteosarcoma (23), Ewing’s sarcoma (16). Proximal fibula pathology was more common (29), distal (five) and diaphyseal (five). Thirty-two patients were treated with wide local excision initially, one below knee amputation, three above knee amputations, two were not fit for surgery and two died while receiving chemotherapy. Two patients required subsequent above knee amputations and one patient a hip disarticulation. Relapse was very common in proximal fibula osteosarcoma. Only 7/23 patients avoided both metastasis and local recurrence. The five-year survival rate of osteosarcoma of the proximal fibula is 33%, distal fibula 100% and diaphyseal 100%. Ewing’s sarcoma of the proximal fibula is 40%, diaphyseal 50% and distal fibula 100%. Conclusion: Despite relatively early presentation of symptoms, the prognosis of proximal fibula osteosarcoma and Ewing’s remains poor. Unlike the prognosis of both distal and diaphyseal pathology, which remains excellent

Introduction. The optimal treatment of elderly patients with unstable ankle fractures is a widely contested and as yet unresolved issue. Whereas the AO technique of anatomical reduction and plate fixation has been shown to give good functional results it is associated with a wound complication rate of up to 40%. This has led some surgeons to believe the risks of operative intervention are too great. The fibula nail is an intra-medullary device with the benefit of requiring minimal soft-tissue dissection. It provides lateral column support over a greater area than the standard plate. The study aims were to assess the clinical and radiographic outcome of a cohort of patients managed with the Fibula Nail (Acumed). Methods. A prospectively collected group of 36 patients with an unstable Weber B or C fracture were managed with a fibula nail. Outcome measures at one-year follow-up were Olerud and Molander ankle scores, radiographic measurements and complications. Results. At one-year follow-up the average Olerud and Molander score was 89/100. Four patients had died and none were lost to follow-up. Twenty-nine patients had normal radiographic measurements, one required a fusion due to fixation failure and two had signs of osteoarthritis. There were two lateral wound infections which both settled without metal work removal. Conclusions. Our case series has demonstrated similar one-year clinical and radiographical results for the fibular nail as previously published with the standard plate and screw technique with few wound complications. The results do indicate the fibula nail has a role in the management of this notoriously difficult fracture. Whether this cohort continues to do well however is unknown and will be the focus of future research

Aim. We present the greatest study of patients with proximal fibula resection. Moreover we describe a new classification system for tumour resection of the proximal fibula independent of the tumour dignity. Method. In 57 patients the functional and clinical outcome was evaluated. The follow up ranged between 6 months and 22.2 years (median 7.2 years). Indicationfor surgery was in 10 cases benign tumours and in 47 cases malignant tumours. In 32 patients a resection of the peroneal with resulting peroneal palsy was necessary. Results. In 13 of 45 patients, where a resection of the lateral ligament complex was done, knee instability occurred. Patients with peroneal resection had a significant worse functional outcome than patients without peroneal resection. An ankle foot orthosis was tolerated well by these patients. 3 of 4 patients with pathologic tibia fracture had a local radiation therapy. There was no higher risk of tibia fracture in patients with partial tibia resection. There was a significant better outcome of patients with benign than of patients with malignant tumours. Conclusion. Resection of tumours in the proximal fibula can cause knee instability, peroneal palsy and in case of local radiation therapy a higher risk of delayed wound healing and fracture. Despite the risks of proximal fibula resection good functional results can be achieved

In vitro experiments have shown, that stabilisation of the fibula in complete fractures of the lower leg give more stability compared to a single stabilisation of the tibia. However it is not known how this biomechanical conditions influence the bone healing process. To investigate the effect of fibula stability in tibia fracture healing tibial osteotomies in rats with and without fibula fractures were compared. Male wistar rats (n=18) were operated by a transverse osteotomy of the proximal tibia of the left leg. Fracture was stabilised by intramedullary nailing. In 8 cases an additional closed fibula fracture was performed. The healing period was 21 days. Each whole leg was examined by x-ray. After explantation of the tibia and removing of the nail and the fibula, the tibia was examined by CT-Scan, three-point-bending and histological evaluation. Animals, who had a fibula fracture along with the tibia fracture presented with delayed healing. Density in CT-scan was 30% lower (p=0,0002) in animals with a fibula fracture (405mg/ccm, SD:64) compared to those without a fibula fracture (mean=577mg/ccm, SD:17). In three point bending the bending stiffness was 79% lower (p=0,0006) in animals with a fibula fracture (mean=252Nmm/mm, SD:118) compared to animals without a fibula fracture (mean=1219Nmm/mm, SD:478). The breaking force was 59% lower (p=0,0004) in animals with a fibula fracture (mean=17,5N, SD:6) compared to animals without a fibula fracture (mean=42,4N, SD:14). Complete fractures of the lower leg healed considerably worse than solitary fractures of the tibia. We conclude that the missing of rotational stability of our k-wire fixation of the tibia with a unfixed fibula fracture is one of the reasons for the delay in fracture repair. The results support the in vitro findings of the biomechanical importance of the fibula for the stability of tibia fractures

Background:. The axis of the fibula in the sagittal plane are known as a landmark for the extramedullary guide in order to minimize posterior tibial slope measurement error in the conventional total knee arthroplasty (TKA). However, there are few anatomic studies about them. We also wondered if the fibula in the coronal plane could be reliable landmark for the alignment of the tibia. This study was conducted to confirm whether the fibula is reliable landmark in coronal and sagittal plane. Methods:. We evaluated 60 osteoarthritic knees after TKA using Athena Knee (SoftCube Co, Ltd, Osaka, Japan) 3-D image-matching software. Angle between the axis of the fibula (FA) and the mechanical axis (MA) in the coronal and sagittal plane were measured. Results:. The mean angle between the FA and MA was 0.86 ± 2.0° of varus in the coronal plane (range 6.0° of varus to 4.2° of valgus) and 2.6 ± 2.3° of posterior inclination in the sagittal plane (range 6.8° of posterior inclination to 2.8 of anterior inclination), respectively. The percentage of subjects in which FA was within 3° of the MA was 77% in the coronal plane and 58% in the sagittal plane, respectively. Conclusions:. The FA used as a landmark for the alignment of the tibia in the conventional TKA differed from MA relatively in this study, and not be used safely if the differences are considered

Purpose. This study compares outcomes in patients with complete congenital fibula absence treated with an amputation protocol to those using an extension prosthesis. Introduction. Complete fibula absence presents with significant lower limb deformity. Parental counselling regarding management is paramount in achieving the optimum functional outcome. Amputation offers a single surgical event with minimal complications and potential excellent functional outcome. Method. 32 patients were identified. 9 patients (2M: 7F, median age at presentation of 22yrs) utilized an extension prosthesis. 23 patients (16M: 7F, median age at presentation of 10 months) underwent 25 amputations during childhood: only two underwent tibial kyphus correction. Mobility was assessed using SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. Results. 19 Syme and one Boyd amputation in 19 patients were performed early (mean age 15 months). 4 Syme and one trans-tibial amputation in 4 patients took place in older children (mean age 6.6 years). K Scores were significantly higher (mean 4 versus 2) and pain scores lower in the amputation group allowing high impact activity compared to community ambulation with an extension prosthesis. The SIGAM and PedsQL scores were all better in the amputation group, but not significantly so. Conclusion. Childhood amputation for severe limb length inequality and foot deformity in congenital fibula absence offers excellent short term functional outcome with prosthetic support. The tibial kyphus does not need routine correction and facilitates prosthetic suspension. Accommodative extension prostheses offer reasonable long term function but outcome scores are lower

Introduction: Extent of fibular resection dramatically alters limb function. Aim of our study was to evaluate the functional outcome following resections for 23 malignant tumors of fibula. Methods: 23 biopsy proven malignant tumors of fibula were included in the study. There were 11 cases of Ewings sarcoma (PNET), 8 osteosarcomas, 2 malignant fibrous histiocytoma and 1 each of synovial sarcoma and chondrosarcoma. Following chemotherapy (wherever indicated) limb salvage surgery was done in all cases. There were 9 proximal, 6 middle and 9 cases of distal third of fibula. Type I resection was done in all proximal and 4 tumors of middle third fibula. Type II fibular resection with reconstruction of ankle joint was done in 10 cases. Reversal of contralateral fibula to reconstruct the ankle was done in 7 cases. Allograft was used in 3 patients. Results: Average follow up was for 4.5 years (2 to 7 years). 17 patients (68%) were alive after 4 years of surgery. Local recurrence was seen in 3 cases and these were treated by above knee amputation. 3 patients died within 1 year of surgery. 82% of survivors had a good to excellent functional outcome according to the MSTS functional evaluation criteria and 65% were able to bear full weight and had unlimited activity. Recurrence was commonest in patients with PNET. All patients undergoing reversed fibular grafting showed good functional outcome. Discussion and Conclusion: Results of limb salvage in malignant fibular lesions is infrequently reported. Site of fibular lesion is critical in salvage surgery and need for further reconstruction. Good results are obtained with reversed contralateral fibular reconstruction of the ankle

Purpose. This study compares outcomes in patients with complete congenital fibula absence, associated with severe lower limb deformity, treated with an amputation protocol to those using an extension prosthesis. Method. 32 patients were identified. 9 patients (2M: 7F, median age at presentation of 22 yrs) utilized an extension prosthesis. 23 patients (16M: 7F, median age at presentation of 10 months) underwent 25 amputations during childhood: only two underwent tibial kyphus correction to facilitate prosthetic wear. Mobility was assessed using the SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. Patients undergoing amputation were further subdivided by age, below and above 2 yrs at the time of surgery. Results. 19 Syme and one Boyd amputation in 19 patients were performed early (mean age 15 months). 4 Syme and one trans-tibial amputation in 4 patients took place in older children (mean age 6.6 years). K Scores were significantly higher (mean 4 versus 2) and pain scores lower in the amputation group allowing high impact activity compared to community ambulation with an extension prosthesis. The SIGAM and PedsQL scores were all better in the amputation group, but not significantly so. There was no significant difference in the scores based on the time of amputation. Conclusion. Complete fibula absence can present with significant lower limb deformity. Parental counselling regarding management is paramount in achieving the optimum functional outcome. Childhood amputation for severe limb length inequality and foot deformity in congenital fibula absence offers excellent short term functional outcome with prosthetic support. The tibial kyphus deformity does not need routine correction and facilitates prosthetic suspension. Accommodative extension prosthesis does offer reasonable long term function but outcome scores are lower

Purpose: Reconstruction using a revascularised fibula has advantages in terms of remodelling the transplant to the stress forces and of better resistance against infections. Osteosynthesis offers mechanical advantages (stabilisaton facilitating primary and stress fracture healing) but with the risk of preventing hypertrophy of the fibula which is not exposed to the stress forces. Material and methods: Our series of 25 vascularised fibular transfers (maximum follow-up 15 years) concerned post-trauma tissue loss (11 cases) and tumour resections (14 cases). For this study of remodelling, we retained only oncological reconstructions because in the event of trauma sequelae, many factors can interfer (infection, preservation of the homolateral fibula with tibial tissue loss). None of the patients were lost to follow-up and remodelling was assessed at two years or more. Results: There was one failure requiring leg amputation (infected nonunion of the distal tibia on a radiated osteo-sarcoma). All the other fibulae healed. Three metaphyseal resections of the distal femur were assembled with a lateral plate using the fibula as a medial strut under compression. This type of assembly favours remodelling and excellent results were obtained in three cases. Five arthrodeses of the knee were performed using a fibula with a femorotibial nail. Healing was slow and the fibula thickened little, particularly when it was simply apposed on the tutor (three cases) rather than encased under compression (two cases). For five proximal humeri, use of a thin plate in three cases (forearm plate) was sufficient to allow healing without inhibiting remodelling. Discussion: For the lower limb, good remodelling is obtained with an assembly allowing compression of the fibula placed medially to the shaft alignment. For metaphyseal loss, we advise a lateral plate with a fibular strut medially. For arthrodesis, a nail is probably more prudent. The position of the lateral tutor decreases the stress on the fibula and is recommended less than the medial strut position. For the humerus, synthesis is required but may be minimal to allow optimal remodelling. Conclusion: Vascularised fibula transfer is a reliable technique which can be recommended for major resections (mean 160 mm) in active subjects. Axial compression forces applied to the graft and use of light osteosynthesis appear to favour healing and remodelling

Aims:Vascularized fibula has been widely used in limb salvage surgery to reconstruct large bone defects. Aim of this study is the analysis of the complications related both to the donor and the recipient site in a series of patients affected by bone tumors. Material and methods: In the period from 1988 to 2002, 114 patients ranging in age between 4 and 64 years underwent bone reconstruction by mean of a vascularized fibula graft. There were 64 men and 50 women and all them were affected by malignant neoplasm. The upper limb was involved in 25 cases and the lower extremity in 89 cases. The length of resection ranged between 7 and 28 cm, the follow up between 6 and 166 months. Results: Several complications have been noted either at the donor or at the recipient site. The most common complications affecting the donor leg, have been the retraction of flexor tendons (6), the valgus deformity of the ankle (3) the retraction of extensor hallucis longus (1) and a transient palsy of the peroneal nerve (1). The most frequent complications observed at the recipient site has been a fracture of the graft (15) followed by non union (12), infection (5 cases), failure of plate (5), skin necrosis (4), transient palsy of the peroneal nerve (3) and joint stiffness. Because of complications, a total failure of the procedure occurred in 4 cases. Conclusions: Although the vascularized fibula graft is the recommended procedure in dealing with challenging reconstruction of large diaphyseal defects, this option is not free of complications. However, in our experience, when conservative treatment of complications was not successful, further surgery was able to lead to recovery in the majority of cases

Introduction. Different techniques for fixation of lateral malleolus have been described. We report our results of using fibula rod for unstable ankle fractures in level one major trauma centre. Methods. We reviewed the results of 40 ankle fractures (14 open and 26 closed) with significant soft tissue injuries and open fractures that were treated with a fibula rod between 2012 and 2015. The median age of patients was 60 (17–98 years). Results. Satisfactory fracture reduction was achieved in all of these patients Two patients had loss of syndesmosis fixation. All fibula fractures healed but 3 medial malleolus non unions occurred which did not need further surgery. 1 patient developed post-operative deep infection and had removal of metalwork. The median physical component Short-Form 12 (PSF12), Olerud and Molander score (OMS), and American Academy of Orthopaedic Surgeons Foot and Ankle outcome scores (AOFAS) were 40 (19 to 52), 57 (0 to 85) and 75 (20 to 95), respectively. The median PSF12, OMS and AOFAS were 33, 35 and 47 for open fractures and 42, 60 and 78 for closed fractures respectively. Conclusion. Using the fibula rod resulted in good radiological and satisfactory functional outcomes with minimal complications. In spite of lower scores in the open fracture group, only one patient needed removal of metal work for deep infection. We recommend using the fibula rod in unstable ankle fracture in patients with significant soft tissue injuries and consider its use in open injuries

Competence of the extensor mechanism is the major determinant of functional outcome after resection of the proximal tibia and tumor prosthesis implantation. Restoration of a compromised active extension of the knee and an extension lag still remains a difficult challenge. Various techniques have been proposed in the past twenty years including direct attachment of the patellar ligament to the prosthesis, transposition of the medial gastrocnemius muscle possibly associated with other muscle flaps, transposition of the fibula and combination of these techniques. Transposition of the fibula was first reported by Kotz in 1983 but not sufficiently described, so that surgeons who want to plane and manage such a procedure can have some difficulties. We present our technique of fibula transposition and report the functional results about seven patients treated for high-grade sarcomas of the proximal tibia. Fibula transposition is carried out only if the entire fibula and its soft-tissues can be preserved. Resection of the tumor and reconstruction is carried out using the same anteromedial approach. After implantation of the prosthesis, the fibula and its muscles are mobilized anteriorly in a ‘baionnette’ shape obtained by performing a two-level osteotomy. The peroneal nerve and the anterior tibial vessels are previously identified and released to prevent tension on these structures during transposition. Care must be taken to preserve as much as possible the muscular insertions on the fibula so that probability of bone fusion increases. The biceps tendon and the lateral collateral ligament inserted in the fibular head are sutured to the patellar ligament. The knee is immobilized in a knee-ankle orthosis for 6 weeks. We have performed this technique in seven cases. A medial gastrocnemius muscle flap was associated in 3 cases to cover the prosthesis. Fusion was achieved in all cases. Full active extension was obtained in all cases with an extensor strength rated 5/5. All patients were ambulatory without external support at the last follow up
