Free Vascularized Fibula Graft as Primary Salvage Procedure for Acute Cervical Osteomyelitis Caused by Epidural Abscess.

Acute cervical osteomyelitis due to an epidural abscess and pyogenic spondylodiscitis in an immunosuppressed patient with progressive myelopathy is a challenge for the reconstructive surgeon. This report presents our novel approach to treat such a condition in a 56-year-old patient in whom antibiotic treatment and decompression of the medulla by laminectomy of C4-C6 failed. Under general anesthesia, debridement of all infected tissue, including anterior corpectomy of C4-C6, was performed. Simultaneously, a free vascularized fibula graft (FVFG) was harvested, adapted to the bone defect, and anastomosed to the superior thyroid artery and external jugular vein. The graft was stabilized with an anterior plate. A scheduled posterior stabilization was performed 1 week later. Staphylococcus aureus was cultured from bone samples and was treated with antibiotics. The postoperative course was uncomplicated besides a dorsal midline defect 6 weeks postoperatively that was closed with a sensate midline-based perforator flap. Five years on, the patient is infection free, and regular control computed tomography and magnetic resonance imaging scan images show progressive fusion and hypertrophy of the fibula to C3/C7 vertebrae. An FVFG combined with posterior stabilization could be a promising primary salvage procedure in cases with progressive myelopathy caused by acute cervical osteomyelitis due to spinal infection. The FVFG contributes to blood circulation, delivery of antibiotics, and an immunological response to the infected wound bed and can stimulate rapid fusion and hypertrophy over time.

Can locking plate fixation and free Vascularised fibular transfer with skin island achieve good functional outcome in the treatment of large bone defects of Tibia ? A study of 26 cases

BackgroundDespite the availability of multiple treatment options, management of tibial bone loss continues to be a challenge. Free vascularized fibula graft (FVFG) with a skin paddle offers better advantages over the other methods. We aimed to study the functional outcomes and QALY of patients with large tibial bone defects following FVFG with a locking plate in 26 patients. Materials and MethodsWe analyzed 26 consecutive patients with large tibial bone defects treated by free vascularized fibular graft (FVFG) and stabilization using a long locking plate between 2009 and 2018. All were followed up for a mean period of 42 months (24 months to 120 months). Bony union, graft hypertrophy, and complications such as stress fracture and infections were assessed. Multivariate regression analysis was performed to identify any association between demographic factors, injury characteristics, treatment-related factors, and fibular hypertrophy. Additionally, The EQ-5D quality-of-life (QOL) indices were obtained using the SF-12 score to evaluate the patients' overall quality of life. ResultsThe mean age of the patients at the time of presentation was 36.26 yrs (range, 18–60 years). The cause of bone loss was open injury in 16 patients and infected nonunion in 10 patients. Complete union was achieved in 25 patients (96 %) without any requirement of additional surgical procedures. The mean union time of the graft was 4.04 months (range, 3–6 months). The mean fibular hypertrophy calculated by De Boer index was 0.61 %, 11 %, 28.24 % and 52.52 % at 3,6 months and 1 and 2 years respectively. Patients with metaphyseal bone loss have significant fibular hypertrophy. Participants in our study experienced a quality of life equivalent to 0.88 (range 0.79–0.99) of perfect health. ConclusionsFVFG with skin paddle and LCP fixation for massive tibial bone loss achieved satisfactory outcome and QALY even in the challenging healthcare environment of South India, a developing country.It maintains alignment, promotes graft hypertrophy, and prevents stress fractures.

Long-Term Results in the Treatment of Avascular Necrosis of Femoral Head with Free Vascularized Fibular Graft

Objective: to evaluate outcomes of vascularized fibula flap used for Avascular necrosis of femoral head. Outcomes were recorded by post-operative Harris hip and radiological improvement of the femoral head. Study Design: Retrospective longitudinal study. Place and Duration of Study: Department of Plastic Surgery, Shifa International Hospital, Islamabad Pakistan, from Jan 2019 to Jan 2020. Methodology: Cases were recruited from 2005-2018 (SIH) performed by the same Orthopaedic and Plastic Surgeon. Data from 30 patients was reviewed. Ethical approval and consent of the patient were taken before the utilization of their data. Results: A total of 30 patients were included, comprising 27(90%) males and 3(10%) females. The mean age was 28.3± years. Pre-operative Harris Hip scores were fair in 17(56.7%) and poor in 13(43.3%) patients. Post operatively these scores improvedv and were noted to be excellent in 10(33.3%), good in 18(60%) and fair in 2(6,7%) patients. Radiological improvement was seen in 20(80%) patients, 8(23.3%) showed no change and 2(6.7%) went into progression. The radiological improvement was significantly associated with aetiology (p=0.004) and Avascular necrosis of HIP (p=0.007). Conclusion: A vascularized fibular graft is an effective treatment option for avascular necrosis of the femoral head in terms of improved radiological outcomes and post-operative Harris Hip scores.

Biological Prosthesis (Hollow 3D-Printed Titanium Custom-Made Prosthesis and Bone Graft) for Humeral Reconstruction in Pediatric Oncologic Patients: Surgical Indications and Results.

This study presents the mid-term outcomes of a novel "biological prosthesis" for pediatric humerus reconstruction after major bone tumor removal. This approach involves a hollow 3D-printed titanium custom-made prosthesis combined with bone grafting. The primary aim was to preserve and revitalize the unaffected autologous proximal or distal humeral stump. Between 2017 and 2021, we treated five pediatric patients (mean age 11.2 years; range 7-17) with humeral bone sarcomas. A one-stage surgical procedure involved tumor resection and implanting a hollow 3D-printed custom-made prosthesis. In two cases, we preserved the proximal humerus; in two, the distal part; and in one, both. Graft materials included homologous bone chips in three cases and free vascularized fibular grafts in two cases. All patients were clinically and radiographically assessed after a mean follow-up of 32.2 months (range of 14-68). No significant complications were observed, and no implant revisions were needed. Osseointegration was evident in all cases within eight months post-surgery; vascular support for the remaining autologous stump was demonstrated in all cases. Our hollow 3D-printed custom-made prosthesis and bone grafting offer the potential for partial or complete articular surface preservation. This approach encourages revascularization of the epiphysis, leading to satisfactory outcomes in humerus reconstruction within the pediatric population.

Combining non-vascularized fibula and cancellous graft in the masquelet technique: A promising approach to distal femur compound fracture management with large defects

IntroductionCompound fractures of the distal femur with large defects pose a significant challenge in management, with several options available, including external fixators, bone grafting, the Masquelet-induced membrane technique, and free vascularized fibular grafts. The Masquelet-induced membrane technique involves placing a cement spacer in the defect to create a biologically active membrane. In the second stage, the gold standard for filling the defect is an autologous cancellous bone graft of 1–2 mm in size. This study aims to examine the effects of using a non-vascularized fibula as a support combined with a cancellous graft in the Masquelet technique for treating compound fractures of the distal femur. MethodsThe study was conducted between December 2017 and December 2020 and included 11 patients who underwent the Masquelet technique. The procedure involved a lateral locked plate and an antibiotic-impregnated bone cement spacer, followed by a 20–30 mm longer ipsilateral fibula used as a strut graft. The remaining area was filled with cancellous bone from the iliac crest. The size of the defect, Time to the bony union, the average range of motion of the knee, and any complications are analysed. The final evaluation was done at 18 months using the Lower Extremity functional scale to assess functional outcomes. ResultsThe study included 11 patients (8 male and 3 female) with a mean age of 45.8 years. The average time to bony union was 6.6 months, and the average range of motion of the knee was 2.2° to 93.3 ° (0–110 °). No complications such as infection, non-union, or implant failure were observed. ConclusionThe Masquelet Technique combined with a fibular strut graft is a feasible solution for complex distal femur fractures with bone loss. The non-vascularized fibula graft provides both structural support and reduces the amount of cancellous bone graft needed, which results in earlier weight bearing and improved functional outcomes.

The Use of Free Vascularized Fibula Graft in Spinal Reconstruction: A Comprehensive Systematic Review.

The extensive search included the following databases: PubMed, ScienceDirect, Web of Science, Cumulative Index to Nursing and Allied Health Literature, and Cochrane for relevant studies published up to January 20, 2023, according to PRISMA 2020 guidelines. Demographic data, flap success, recipient vessels, and flap-related complications were evaluated. We identified 25 eligible studies involving 150 patients, consisting of 82 men and 68 women. Spinal reconstruction utilizing FVFG is mostly reported in the case of spinal neoplasm, followed by spinal infection (osteomyelitis and spinal tuberculosis) and spinal deformities. The cervical spine is the most common vertebral defect reported in the studies. All studies summarized in the present study reported successful spinal reconstruction, while wound infection was the most reported postoperative complication after spinal reconstruction utilizing FVFG. The results of the current study highlight the ability and superiority of using FVFG in spinal reconstruction. Despite being technically challenging, this strategy provides enormous benefits to patients. However, a further additional large-scale study is required to corroborate these findings.

Free vascularized fibula graft for staged reconstruction of infected humerus nonunions.

To evaluate the union rate and rate of post-operative complications in patients with septic nonunions of the humerus following a two-stage reconstruction using a free vascularized fibula graft. Retrospective case series. Academic, tertiary referral center. Adult patients with staged reconstruction for infected nonunion of the humerus with at least 2 years follow up after vascularized fibula graft transfer. First, infected nonunion debridement with antibiotic spacer and external fixator placement. After antimicrobial treatment, free vascularized fibula transfer with internal fixation. Time to union, pain, affected extremity range of motion and function. 10 patients with septic humerus nonunion treated with staged reconstruction using a free vascularized fibula graft, with a mean follow-up of 32.3 months were included. Following the two-stage reconstruction using a free fibula, radiographic union was achieved in 6/10 patients, with a mean time to union of 19.9 weeks. The remaining four patients required an additional procedure with graft augmentation and/or implant revision. After the revision procedure, union was noted in 3/4 patients, 21 weeks post-operatively. Mean patient visual analog scale pain scores improved from 5.8 pre-operatively to 0.9 at final follow up (p=0.02). Post-operatively mean elbow flexion was 110±20 degrees and extension 15±7.5 degrees. A two-stage reconstruction using a free fibula graft can be used in patients with septic nonunions of the humerus in the setting of multiple failed prior surgeries and compromised local biology. Additional procedures may be needed in some to achieve final union. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Management of bone loss in acute severe open tibial fractures: a retrospective study of twenty nine cases-a treatment strategy with bone length preservation.

The present study investigated the outcomes of bone loss associated with acute open tibial fractures classified as Gustilo-Anderson classification grade III B (GIIIB) using a bone length preservation strategy. Among acute GIIIB open tibial fractures, 29 limbs of 29 patients requiring bone loss treatment were included. The reconstruction methods for bone loss were selected among the Masquelet technique (MT), bone transport (BT), acute shortening followed by gradual lengthening (ASGL), and free vascularized fibula graft (FVFG). Primary outcome measures were the rate of bone union and time to bone union. The median radiographic apparent bone gap (RABG) was 46.75mm. Bone loss was treated with ASGL only in two patients in whom it was not possible to cover large soft tissue defects by a single free latissimus dorsi (LD) myocutaneous flap (with the serratus anterior (SA) muscle). The other 27 patients underwent soft tissue reconstruction and bone loss treatment with the preservation of bone length, including the MT for 23, BT for six, and FVFG for one. The bone union rate was 75.9%, and the median time to bone union was six months. Salvage surgeries were performed on all seven patients with nonunion; all of whom eventually achieved bony union. Bone loss associated with acute GIIIB open tibial fractures were treated with "bone length preservation" if the size of the soft tissue defect was less than the size that was covered by a single LD myocutaneous flap (with the SA muscle).

Outcomes of Sling Procedure Using a Free Vascularized Fibular Graft After Resection of the Proximal Humerus.

The proximal humerus is a common site for both primary and metastatic bone tumors. Although various methods have been developed for reconstruction following resection of the proximal humerus, a consensus on which technique is best has not been established. We focused on the sling procedure using a free vascularized fibular graft (FVFG) and conducted what we believe to be the largest retrospective study of patients to undergo this surgery to date. We retrospectively reviewed the data of 19 patients who underwent the sling procedure with use of an FVFG at our hospital between 1998 and 2022. The median age was 20 years, and the median follow-up duration was 63.1 months. Surgical data, oncological outcomes, the postoperative course, complications, and functional outcomes as measured with use of the Musculoskeletal Tumor Society (MSTS) score were thoroughly reviewed. The median operative duration was 555 minutes, and the median blood loss was 374 mL. The median length of the bone defect was 17.0 cm, and the median length of the graft was 20.0 cm. With respect to oncological outcomes, 9 patients were continuously disease-free, 9 patients had no evidence of disease, and 1 patient was alive with disease. Bone union was present in 13 of the 17 patients for whom it was evaluable. The median time to bone union was 4 months. Graft growth was observed in 2 pediatric patients. Postoperative fracture was a major complication at the recipient site. The incidence of pseudarthrosis significantly increased when the FVFG could not be inserted into the remaining humeral bone or was split in half (p = 0.002). Although a few patients demonstrated peroneal nerve palsy at the donor site, the symptom was temporary. The overall functional outcome was favorable, with an average MSTS score of 66.9%. The sling procedure demonstrated a low complication rate and a favorable functional outcome overall. Therefore, we believe that this procedure is a useful reconstruction method for patients in a broad age range who have a wide defect of the proximal humerus. Therapeutic Level IV.

Use of Three-Column Reconstruction and Free Vascularized Fibular Grafts for the Repair of Large Tibial Defects after Tumor Resection.

This study aimed to evaluate the clinical outcomes of three-column reconstruction of the lower leg using a single-barrel contralateral vascularized fibular graft (VFG), medial locking plate, and the ipsilateral fibula for the repair of large tibial defects after tumor resection. In this retrospective study, we reviewed 12 patients who underwent three-column reconstruction using a single-barrel contralateral VFG, medial locking plate, and the ipsilateral fibula between June 1996 and May 2020. These patients had large tibial bone defects following tumor resection. The mean age of the patients was 26.3 years (range, 11-63 years), and 7 of them were women. The mean follow-up period was 104.8 months (range, 26-284 months). The mean size of the tibial bone defect after tumor resection was 17.8 cm (range, 11-26.8 cm). The clinical and radiological outcomes were evaluated at the final follow-up. All patients survived beyond the final follow-up without recurrence of the primary bone tumor. The mean time from reconstruction to bony union at both host-graft junctions was 12.9 months (range, 4-36 months). The mean Musculoskeletal Tumor Society score was 82.3% (range, 60%-97%). All tibial defects were reconstructed with adequate bone healing. There were 4 cases of stress fracture and graft failure; these were resolved by using longer plates and more screws. All patients were ambulatory without assistance and showed no permanent complications. Large tibial defects that occur after tumoral resection can be effectively reconstructed by three-column reconstruction using a medial locking plate, an inlay single-barrel VFG harvested from the contralateral side, and the intact ipsilateral fibula. This technique permits early weight-bearing before fibular hypertrophy and bony union.

Outcomes of total hip arthroplasty after failed free vascularized fibular grafting for osteonecrosis of the femoral head.

Total hip arthroplasty (THA) after vascularized fibular grafting (VFG) is technically demanding with poorer outcomes compared to primary THA in patients with osteonecrosis of the femoral head (ONFH). The purpose of this study was to compare the outcomes of THA after VFG after removal of the graft with that of primary THA. ONFH patients treated by VFG at a single institution were studied retrospectively. THAs after VFG performed by single arthroplasty surgeon with a single type of THA prosthesis were enrolled in the study. A control cohort of patients was created by 1:1 matching with the THA after VFG cohort according to age, gender, and American Society of Anesthesiology (ASA) score from ONFH patients treated by primary THA. Early and long-term outcomes were compared between the two groups. A total of 24 hips were included in the THA after VFG group and compared with 24 primary THA hips. No significant difference was noted in stem position. The THA after VFG group had increased blood loss and longer duration of operation time. There were two cases of intraoperative femur fractures in the THA after VFG group. The femoral stem of both groups were stable, with no cases of revision, and similar HHS scores at the last follow-up. THA after VFG may have similar short to midterm outcomes with primary THA after removal of the residual abutting bone graft and correct positioning of the femoral stem.

Clinical results of free vascularized fibula graft in the management of precollapse osteonecrosis of the femoral head: A retrospective clinical study.

This study aimed to evaluate clinical results, femoral head survival, and the need for total hip arthroplasty (THA) in patients with precollapse osteonecrosis of the femoral head (OFH) (Steinberg stage II and III) treated by free vascularized fibula graft (FVFG) application. We retrospectively reviewed 54 hips of 47 patients (39 males, eight females; mean age 36 ± 14 years) who underwent FVFG due to OFH, with at least two years of follow-up. The patient data, including Harris Hip Score (HHS), Visual Analogue Scale (VAS), and conversion to THA, were documented. The right hip of 26 patients and the left hip of 28 patients were involved. Bilateral FVFG surgery was performed on seven patients due to bilateral OFH. The mean follow-up time was 5.5 (range 2-14) years. Survival of the femoral head was observed in 39 hips (72.2%), while the femoral head collapse was observed in 15 femoral heads (27.8%). The mean preoperative HHS increased from 46.5 (range=12-85) to 86.5 (range=33-100) postoperatively (P < 0.001). The mean preoperative VAS score improved from 8.2 (range=2-10) to 1.3 (range=0-10) postoperatively (P < 0.001). THA was performed on seven hips at a mean follow-up time of 1.8 years (range=0.7-3.3). There was no significant difference in the collapse rate between unilateral or bilateral OFH (P=0.175). A higher survival rate was observed in the Steinberg stage II femoral head patients compared to the stage III femoral head (P=0.021). This study has shown that FVFG surgery can be a good option for managing patients with Steinberg stage II and III precollapse OFH to prevent femoral head collapse and joint function.

Primary bone tumors and tumor-like lesions of the wrist: a single-center experience

Aim: The incidence of primary bone tumors of the wrist is increasing. The aim of this study was to examine the characteristics, treatment protocols, complication rates, and functional outcomes of bone tumors of the wrist treated in a tertiary orthopedic oncology center.&#x0D; Material and Method: We retrospectively analyzed 93 patients with bone tumors located in the wrist (63 distal radius, 23 distal ulna, 7 carpal bone) who were operated on between 2005 and 2020. Demographic information was recorded. Functional outcomes were evaluated with the Musculoskeletal Tumor Society System (MSTS) scoring system.&#x0D; Results: There were 57 male and 36 female patients. The average follow-up period was 32 months (range 16-163). There were 82 benign and 11 malignant lesions. Distal radius was the most common site of involvement. The most common type of benign tumor in the distal radius and distal ulna was the giant cell tumor (GCT; 26 and 10 patients, respectively). Among the malignant tumors in the distal radius, 5 were Ewing sarcoma, and 2 were osteosarcoma. All patients with malignant lesions underwent wide surgical resection and free vascularized fibular graft (FVFG) reconstruction. Of the malignant tumors in the distal ulna, 3 were Ewing sarcoma, and 1 was osteosarcoma. These were treated with wide resection and FVFG reconstruction (n=3) and wide resection and fibular strut graft (n=1). The rarest site for tumors in the wrist was the carpal bones. Carpal bone lesions included scaphoid (n=5) and lunate (n=2) tumors. In all of these patients, pathological examination indicated intraosseous ganglion cysts. The average MSTS score of all patients was 27 (range 24-30). Of the 36 patients with GCT, 4 (11%) developed local recurrence. One patient with Ewing sarcoma developed local recurrence and underwent secondary amputation. Distant lung metastasis was observed in 5 of 8 patients with Ewing sarcoma. &#x0D; Conclusion: Our study confirmed that bone tumors in the wrist are rare. Most benign tumors can be treated with curettage and cement augmentation. For malignant tumors, it is possible to restore function with FVFG.

Management of Massive Mandibular Fibrous Dysplasia with Radical Excision and Different Immediate Reconstructive Modalities: Case Series Report.

To review and represent three different mandibular reconstruction modalities following surgical treatment of massive mandibular fibrous Dysplasia (MMFD). The present retrospective case series study was conducted on 24 patients who had MMFD and treated via resection and immediate reconstruction at Al-Azhar University Hospitals, Egypt. Patients were divided into three groups according to the grafting procedure. Group I patients were grafted with iliac bone graft (IBG), group II patients were grafted with IBG and bone marrow aspirate concentrate (BMAC), while group III patients were grafted with free vascularized fibula graft (FVFG). Postoperative clinical and radiographic assessments were performed immediately, at 6months, 12months and 2years to evaluate lesion recurrence and bone graft resorption. Other study variables included assessment of postoperative wound dehiscence, infection rate, amount of edema, and facial bone contour. The parameters of the clinical analysis showed non-statistically significant differences among all groups. Postoperative wound healing was clinically uneventful in all groups, except for two cases of wound dehiscence in group I (8.3%) and one case in group III (4.2%). Most patients had appropriate postoperative facial contour, and adequate facial symmetry. The radiographic measurements revealed a highly statistically significant difference between group I and II at 12months, and twoyears, without any statistically significant difference between group II and III. MMFD surgical defect should be repaired for function and cosmetics aims especially in young adult patients. The findings of the present study have shown that when compared to traditional IBG alone or FVFG, the use of autogenous IBG with BMAC injection produces a favorable outcome with few difficulties.

Patient-Reported Long-Term Outcomes After Free Vascularized Fibula Graft in Spinal Reconstruction: a 24-year Cohort

The use of free vascularized fibula grafts (FVFG) in complex spinal deformity surgery intends to allow for life-long stability of the spine with good long-term clinical outcome. However, these long-term outcomes of this technique are still lacking. The objective of this study is to report the long-term postoperative outcomes and establish the long-term viability of this method for spinal reconstruction. A retrospective cohort study was conducted in all patients who underwent spinal reconstructive surgery utilizing a FVFG at a tertiary medical centre. Questionnaires taken from the participants were the Numeric Pain Rating Scale (NPRS), Oswestry Low Back Pain Disability (also known as Oswestry Disability Index (ODI)), Scoliosis Research Society 22r (SRS-22), the EQ-5D-5L and a self-assembled questionnaire regarding donor site comorbidities and patient satisfaction. Over a period of 24 years (1995-2019), we used FVFG for spinal reconstruction in 31 patients. A total of 25 patients were included in this study, 8 patients were deceased at the time of this study, and sixteen patients responded to the questionnaires. Patient satisfaction was rated 6.8 out of 10, the average SRS-22r score was 3.6, EQ-5D-5L score was 0.725, and the ODI score showed a minimal disability (0-20%) postoperatively. Overall complication-free survival was 8.9 years. Nine patients underwent a re-operation in the spinal area; five for the removal of the spinal instrumentation. Patients reported satisfied and good long-term outcomes following FVFG surgical procedure for complex spinal deformities. Therefore, considering the alternatives, this procedure provides a good long-term solution for complex spinal deformity surgery.

Free Vascularized Fibular Graft for Congenital Pseudarthrosis Tibia: A Case Series

Introduction: Congenital pseudarthrosis tibia (CPT) probably one of the most difficult to treat among all diseases in the children. There are several surgical approaches that have been used to treat CPT including on-lay graft, double on-lay grafts, pedicle grafts, osteotomy, bypass graft and intramedullary rods. Prognosis of CPT has changed considerably with the use of Free Vascularized Fibular Graft (FVFG). Despite these advances, several operations are often necessary to obtain union of CPT and the risk of amputation is never entirely eliminated Case presentation: We presented 2 case with CPT. The first case is a 4 year old girl with CPT-Associated Neurofibromatosis, patient was brought to orthopedic polyclinic complaining bend on her right leg since she was born, the parent also complained her child has abnormality when walking since she was 14 months old. The second case is a 3 year old girl with CPT complaining bend on her right leg, abnormalities and pain when walking since she was aged 1 years 11 months. We performed free vascularized fibular graft for both of the patient. Result: The results in our cases showed bone union in 14 weeks, 16 weeks and 18 weeks respectively. The optimal of technique options should be adapted to the type of pseudarthrosis and especially to the extent of the bone defects. good results can be found with intramedullary nailing with a bone graft or the Ilizarov technique Conclusion: The optimal of technique options should be adapted to the type of pseudarthrosis and especially to the extent of the bone defects Keywords: Congenital pseudarthrosis tibia, Free vascularized fibular graft, case series.

Free Vascularized Fibular Graft

Background: Free Vascularized Fibular Grafts (FVFGs) are currently a mainstay for extreme case reconstruction mainly due to their anatomical characteristics, reliability, and versatility in managing all bone defects cases. Method: This paper is a review article of the journal found by the author suitable for our reference in search engines with the keywords "Free Vascularized Fibular Graft" "surgery" "postoperative" and "complications". Results: FVFG can be used as management of bone defects such as post-trauma, infection or tumor, treatment of congenital abnormalities, avascular necrosis (AVN), arthrodesis, and pediatric pathology. Position Placement, Intercalary Resection, Bone Tumor Resection, Fibula Flap Retrieval, Allograft Preparation, Reconstruction at Recipient Site, and Intra-articular Resection need to be considered in the surgical procedure. Postoperative Monitoring in the ICU is necessary to evaluate Vital signs, flap viability, axle well as complications in patients. Conclusion: FVFG is a choice of bone defect reconstruction techniques with good results to be considered by orthopedic surgeons.

Revision with Locking Compression Plate by Compression Technique for Diaphyseal Nonunions of the Femur and the Tibia: A Retrospective Study of 54 Cases.

Nonunion after diaphyseal fracture of the femur or the tibia is a common but difficult complication for treatment. Currently, the main treatment modalities include nail dynamization, exchange nailing, and bone transport, but revision with compression plating in these nonunions was rarely reported. To evaluate the outcomes of compression plating in the treatment of femur and tibia shaft nonunions, we retrospectively reviewed 54 patients with diaphyseal nonunion of the tibia or the femur treated with locking compression plate (LCP) by compression technique. There were 46 aseptic and 8 septic nonunions in the case series. Patient's history, fracture characteristics, previous interventions, and types of nonunion were recorded. The possible reason which might lead to nonunion was also analyzed for each case. Patients with aseptic nonunions were revised by hardware removal and compression plating with or without bone grafting. For septic nonunions, a two-stage surgery strategy was used. Compression plating with iliac crest bone grafting (ICBG) or free vascularized fibular grafting (FVFG) was used as the final treatment for septic nonunions. The compression technique and bone grafting method were individualized in each case according to the patient's history and architecture of the nonunion. Each patient finished at least a two-year follow-up, and all cases achieved healing uneventfully. Our study showed that compression plating with LCP was an effective method to treat diaphyseal nonunions of the tibia and the femur. It is compatible with different bone grafting methods for both infected and noninfected nonunions and is a good alternative to the current treatment methods for these nonunions.
