One-stage prosthodontically driven jaw reconstruction in patients with benign and malignant pathologies: A 7- to 11-year cohort study.

OBJECTIVES: One stage functional jaw reconstruction is defined as the resection and reconstruction of segmental defects in conjunction with the placement of dental implants in an ideal prosthetic position and loaded with a provisional restoration, during one surgical procedure. The aim of the study is to describe clinical outcomes of patients who underwent one stage functional jaw reconstruction. METHODS: Patients who underwent one-stage functional jaw reconstruction, from January 2013 to March 2016 were recalled in 2022 and 2023. Planning and execution for the reconstruction utilized either analogue or digital techniques. Outcome parameters recorded were treatment-related outcomes at patient level, implant-related outcomes and patient-reported outcome measures. RESULTS: Eighteen patients underwent one-stage jaw reconstruction with a total of 57 implants. Four patients had maxillary and 14 had mandibular reconstructions. Ten patients underwent postoperative radiotherapy. Ten patients were planned using analogue and eight by digital planning. Three patients had partial flap necrosis, three patients had plate fractures, implant loss was seen in one patient and four patients died during the period. A functional prosthesis was provided in 16 out of the 18 patients. CONCLUSION: One-stage functional jaw reconstruction is a predictable method for providing rehabilitation with successful outcomes at 7-11 years. However, caution should be exercised when the treatment modality is carried out in patients with malignant pathologies who have undergone radiotherapy.

Operative treatment of isolated epiphyseal fracture of the distal fibula: 1 case report and literature review.

Pediatric ankle injuries are common; ankle epiphyseal fractures are also common in children. But isolated distal epiphyseal fibular fractures of the distal fibula are clinically rare. We describe one unusual case of an adolescent with a completely displaced Salter-Harris type II distal fibular epiphyseal fracture. The attempt of closed reduction failed, and the patient required open reduction and internal fixation. The localized periosteum and the superior peroneal retinaculum were avulsed from the distal fibular metaphysis, with the peroneal tendons underneath exposed but no obvious subluxation. To the best of our knowledge, this combination of injuries has not been previously reported.

Virtual surgical planning for mandibular reconstruction in an abbreviated admission pathway.

OBJECTIVES: Virtual Surgical Planning (VSP) creates individualized surgical plans for free flap reconstruction of mandibular defects. Prior studies indicate that VSP can offer cost benefits due to reduced operative time and length of stay (LOS). We assessed the impact of VSP in the context of a validated postoperative abbreviated LOS clinical pathway. METHODS: This study assessed patients undergoing VSP vs conventional fibular free flap reconstruction for mandibular defects (12/2015-10/2020) and their operative time, ischemia time, and LOS were evaluated. RESULTS: Forty-four patients underwent VSP reconstruction, while 52 patients underwent conventional reconstruction for mandibular defects. VSP was associated with significantly lower total operative time (6 h and 57 mins vs 7 h and 54 mins, p = 0.011), but not length of stay or ischemia time. Total OR time was significantly increased with increasing number of segments needed in both the VSP group (p = 0.002) and the conventional group (p = 0.015). CONCLUSION: Shorter operative times and LOS have been attributed to the use of VSP in free tissue transfers. It is argued that these reductions offset the added cost of VSP. Our study indicates that there is no cost benefit for VSP utilization due to a significantly reduced operative time with no impact on length of admission in an abbreviated admission clinical pathway following free tissue transfer.

Three-dimensional assessment of upper airway changes associated with mandibular positional deviations following fibula free flap reconstruction.

OBJECTIVES: Fibula free flaps (FFF) are the standard approach to mandibular reconstruction after partial resection, with the goal of restoring aesthetics and masticatory function. The graft position affects both and must be carefully selected. Correlations between sagittal positioning and upper airway anatomy are known from orthognathic surgery. This study aims to evaluate changes in mandibular position and upper airway anatomy after reconstructive surgery with FFF and corresponding correlations. MATERIALS AND METHODS: Mandibular position after reconstruction was evaluated using three-dimensional datasets of pre- and postoperative computed tomography scans of patients treated between 2020 and 2022. Three-dimensional measurements were performed on both condyles and the symphyseal region. Changes in upper airway volume and minimum cross-sectional area (minCSA) were analysed. Intra-rater reliability was assessed. Correlations between changes in upper airway anatomy and sagittal mandibular position were tested. RESULTS: The analysis included 35 patients. Intra-rater reliability was good to excellent. Condylar deviations and rotations were mostly rated as small. Changes in symphyseal position were considerably greater. Median airway volume decreased in the oropharynx and hypopharynx. Posterior deviation of the symphysis was associated with a decreasing minCSA in the hypopharynx and vice versa. CONCLUSIONS: The overall accuracy of mandibular reconstructions with FFF is high, but there is room for optimization. The focus of research should be extended from masticatory to respiratory rehabilitation. CLINICAL RELEVANCE: Effects on respiratory function should be considered prior to graft positioning. The clinical relevance of upper airway changes within the complex rehabilitation of reconstructive surgery patients needs to be further investigated.

Effect of non-vascularized fibular harvest on the donor limb: radiological evaluation at a mean follow-up of twelve point eight years.

PURPOSE: The study is aimed at evaluating the long-term (at a minimum follow-up of 10 years) impact of non-vascularized fibular harvest on the donor limbs. METHODS: There were 27 donor limbs (n = 19 children) available for retrospective radiological review. The graft was obtained bilaterally in eight patients. The following parameters were evaluated in the follow-up radiographs: continuity/non-continuity of fibular regenerate, width of the regenerated fibula, distal fibular station, medial proximal tibial angle, posterior proximal tibial angle, lateral distal tibial angle (LDTA), anterior distal tibial angle, and tibia diaphyseal angulation (interphyseal angles). For analysis and comparisons, the donor limbs were compared to the healthy limbs (controls) of the children with unilateral harvest. Additionally, the impact of continuous and non-continuous fibular regeneration was separately analyzed. RESULTS: The mean child's age at the time of fibular harvest was four years. The mean follow-up was 12.8 years. The fibula was found regenerated in continuity in 22 limbs of 15 children (81.5%). When analyzed as a combined group (both continuous and non-continuous fibular regenerations), all the donor limb radiological parameters matched those of healthy limbs except LDTA (p = 0.04). In the subgroup analysis between non-continuous and continuous fibulae, significant abnormalities were again obvious in LDTA (p = 0.0001). The non-continuous fibulae were significantly lesser in width. All limbs with non-continuous fibular regeneration manifested ankle valgus. CONCLUSIONS: The non-vascularized fibula emerged as a relatively safe procedure in the long term with minimal affections of the knee, ankle, or tibial anatomy when longitudinal integrity of fibula was restored. The non-regenerations of the fibula may be prone to developing ankle valgus.

Osteoperiosteal fibular strut grafting - A technique to improve union rates.

PURPOSE: Gap non-union of long bones are challenging problems in orthopaedic patients. Non-vascularized fibular grafting is a simple, cost effective, single stage procedure and is an accepted method of reconstruction for gap non unions in children. However, there is a risk of non-union when a long avascular strut of fibula is used. The periosteum, by itself has high biological activity and is helpful in osteointegration. Harvesting the fibula with the periosteum gives the advantage of mechanical and biological support in a gap non-union. METHODS: During 2020 to 2022, 13 patients presented to us with gap nonunion of long bones due to various aetiology. The mean age of the patients was six years with a mean bone gap of 4.2 cm. A modified technique of harvesting the fibula with the periosteum is described. The graft was stabilized with the recipient bone by intra medullary or extra medullary implants. RESULTS: Union occurred in average 12.7 weeks in all except one patient with congenital pseudoarthrosis of tibia. The fibula on the harvest site regenerated completely in all other patients. One patient had a superficial infection. Children were followed were an average of 17.5 months and there was no incidence of graft resorption or fracture. Osteoperiosteal fibula graft is a simple, effective and cost-effective procedure for the treatment of gap non-unions in children. It offers the advantage of both biological and mechanical support, with high union rates and low complication rates.

Percutaneous intramedullary screw or rush pin fixation of unstable ankle fractures in patients with fragile soft tissue - retrospective study of 80 cases.

INTRODUCTION: The standard surgical procedure for unstable ankle fractures is fixation of the lateral malleolus with a plate and screws. This method has a high risk of complications, especially among patients with fragile skin conditions. The aim of this study was to estimate the re-operation rates and identify complications in patients with an unstable ankle fracture, surgically treated with an intramedullary screw or rush pin. MATERIALS AND METHODS: We identified all patients who were surgically treated with either a 3.5-mm screw or rush pin at Aarhus University Hospital, Denmark, from 2012 to 2018. Major complications were re-operations within three months. We included 80 patients, of which 55 (69%) were treated with a 3.5-mm intramedullary screw and 25 (31%) with a rush pin. The majority of the study population was female (59) and the mean age was 75 (range 24 to 100) years. Of the 80 patients included, 41 patients had more than 2 comorbidities. RESULTS: Three patients underwent re-operation within three months due to either fracture displacement or hardware cutout. Radiographs obtained after six weeks showed that nine patients had loss of reduction. Additionally, four patients had superficial wound infections and six patients had delayed wound healing. CONCLUSIONS: Intramedullary fixation of distal fibula fractures with either a screw or rush pin has low re-operation rates. However, the high proportion of patients with radiological loss of reduction is concerning.

Better outcomes using suture button compared to screw fixation in talofibular syndesmotic injuries of the ankle: a level I evidence-based meta-analysis.

INTRODUCTION: The present meta-analysis evaluated current level I clinical trials which compared the use of a suture button (SB) versus syndesmotic screw (SS) fixation techniques for syndesmosis injuries of the ankle. The outcomes of interest were to compare patient-reported outcome measures (PROMs) and complications. It was hypothesised that SB might achieve better PROMs along with a lower rate of complications. METHODS: This study was conducted according to the 2020 PRISMA statement. In August 2023, PubMed, Web of Science, Google Scholar, and Embase were accessed. All the randomised controlled trials (RCTs) which compared SB versus SS fixation for syndesmosis injuries of the ankle were accessed. Data concerning the American Orthopaedic Foot & Ankle Society (AOFAS), and Olerud-Molander score (OMS) were collected at baseline and at last follow-up. Data on implant failure, implant removal, and joint malreduction were also retrieved. RESULTS: Data from seven RCTs (490 patients) were collected. 33% (161 of 490) were women. The mean length of the follow-up was 30.8 ± 27.4 months. The mean age of the patients was 41.1 ± 4.1 years. Between the two groups (SB and SS), comparability was found in the mean age, and men:women ratio. The SS group evidenced lower OMS (P = 0.0006) and lower AOFAS (P = 0.03). The SS group evidenced a greater rate of implant failure (P = 0.0003), implant removal (P = 0.0005), and malreduction (P = 0.04). CONCLUSION: Suture button fixation might perform better than the syndesmotic screw fixation in syndesmotic injuries of the ankle.

Knee dislocations and associated fractures: risk factors for surgical reduction.

INTRODUCTION: Dissociation of the knee joint, or knee dislocations (KD), can lead to severe complications, often resulting in multiligament injuries. A subset of these injuries are irreducible by closed reduction and require open reduction. Identifying KDs that necessitate surgical intervention is crucial for optimal outcomes. While previous studies have explored various risk factors, the influence of associated fractures is less understood. MATERIALS AND METHODS: We queried the Trauma Quality Improvement Program (TQIP) database from 2017 to 2021, for non-congenital closed knee dislocations requiring surgery. Demographic variables were collected, and ICD-10 codes were used to identify associated tibia, femur, acetabular, and fibula fractures. ICD-10 codes were also used to identify nerve injuries and vascular injuries. Multivariate logistic regression was used to assess factors influencing the need for surgical reduction (SR). RESULTS: A total of 1,467 patients with KDs were included in the study, of which 411 (28.0%) underwent open surgical reduction (SR) while 1,056 (72.0%) were treated with nonsurgical closed reduction (nSR). Factors associated with SR included concomitant tibia fracture (OR = 1.683, C.I: 1.255-2.256, p < 0.001) and fibula fracture (OR = 1.457, C.I: 1.056-2.011, p = 0.022). Vascular injury had lower odds of SR (OR = 0.455, C.I: 0.292-0.708, p < 0.001). CONCLUSION: Our study demonstrated that KDs presenting with concomitant tibia and/or fibula fractures are more likely to require SR. The difficulty posed to closed reduction may be due to the influence of these fracture patterns on surrounding soft tissue as well as the lack of a stable bone structure necessary for achieving proper reduction. Physicians should be aware of the potential risk of this fracture pattern when caring for patients with KDs.

The role of fibula fixation in combined distal-third tibia and fibula fractures: a systematic literature review.

OBJECTIVE: The role of concomitant fibula fracture fixation in distal-third tibia fractures regarding alignment, union, and functional outcome is still a topic of debate. In this review, we summarize the available comparative literature regarding fibula fixation in distal third lower leg fractures. MATERIALS AND METHODS: A systematic literature review of articles published between January 2000 and January 2022 in the PubMed, Cochrane, and EMBASE databases about this topic was performed. RESULTS: 746 unique studies were identified of which four randomized-controlled trials and six retrospective studies were included. Nine studies compared alignment after tibia fixation with or without fibula fixation, six studies reported on tibial union, and three studies reported on functional outcome between groups. Pooling of data was not possible due to varying outcome measures and inclusion criteria. Fibula fixation was associated with less rotational malalignment, while there does not seem to be consensus regarding the effect on sagittal and coronal alignment. Six studies reported on the effect of fibula fixation on tibial union. None of these studies found a significant difference between treatment modalities. Furthermore, one out of three studies reporting functional outcome described a marginal beneficial functional outcome after fibula fixation. Ultimately, no differences in complication rates between treatment modalities were described. CONCLUSION: Fixation of the fibula in distal-third lower leg fractures does not seem to have a significant effect on coronal and sagittal tibial alignment. Furthermore, fibula fixation is associated with significantly less rotational malalignment, although the clinical importance of this finding is questionable as true differences in rotational alignment between treatment modalities are small. Finally, fibula fixation does not affect union, functional outcome, or complication rate as adjuvant to tibia fixation. LEVEL OF EVIDENCE: II.

Should We Fix the Fibula in Tibial Plafond Fractures? A Meta-analysis Reviewing the Evidence Base for Fibula Open Reduction and Internal Fixation in Tibial Plafond Fractures.

Open reduction and internal fixation are the standard of care to stabilize tibial plafond fractures. However, it remains uncertain as to whether fixation of the fibula affects the outcome. This study aimed to review the evidence base for comparable outcomes in tibial plafond fractures when undergoing open reduction and internal fixation of ipsilateral fibula fractures compared with open reduction and internal fixation of the tibia alone. A systematic review and meta-analysis of the literature was completed; 4 studies were included for analysis. This study demonstrated no statistically significant differences in the incidence of nonunion (p = .784) or mal-union (p = .416). There was a greater rate of removal of metalwork in the fibula operative group compared to the tibia alone group (p < .001). The current evidence demonstrates that open reduction and internal fixation of ipsilateral fibula fractures in tibial plafond fractures is not necessarily routinely indicated for all fractures.

Takedown of Ankle Arthrodesis and Conversion to Total Ankle Arthroplasty: A Systematic Review.

Management of the nonunited or painful ankle arthrodesis remains a difficult challenge. The aim of this systematic review was to investigate the clinical outcomes and complications of conversion of an ankle fusion to a Total Ankle Replacement (TAR). The PRISMA statement guidelines were followed. A literature search was performed in Pubmed, Science Direct and Cochrane Central Register of Controlled Trails (CENTRAL) from their inception up to October 10th, 2023. The quality of the included studies was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal tool and the Methodological Index for Non-Randomized Studies (MINORS). Seven studies with 220 patients (223 ankles) with a mean follow-up of 64.9 months were included. Takedown of an ankle fusion and conversion to a TAR led to a significant improvement in all functional and clinical scores and with an acceptable range of motion. Most common complications were malleolar fractures (12.8%) and arthrofibrosis (5.6%). The revision rate was 8% and four cases resulted in a below-knee amputation. Cases with an insufficient fibula had a good outcome when a fibular reconstruction was performed. In conclusion, takedown of an ankle fusion and conversion to a TAR has satisfactory clinical outcomes and with a limited number of complications. Future well-designed studies are needed to validate the results of the present study.

[Clinical analysis of denture rehabilitation after mandibular fibula free-flap reconstruction].

OBJECTIVE: To evaluate the postoperative denture restoration and denture function in patients with mandibular defect reconstructed with vascularized free fibula flap. METHODS: In the study, 154 patients who underwent mandibular segment resection and used vascularized free fibula flap to repair mandibular defects due to inflammation, trauma and tumor from January 2015 to December 2020 were collected. These patients had common inclusion criteria which were stable occlusal relationship before operation, segmental defects of mandibular bone caused by lesions of mandible and adjacent parts (such as floor of mouth, tongue, cheek), free fibula flap used for repair and surviving after operation. Relevant data were reviewed and situation of denture restoration was followed up. A questionnaire related to denture functional evaluation had been proposed for those who had completed the denture rehabilitation. The evaluation index of denture restoration function was assigned by expert authority to obtain the denture function score. SPSS 18.0 software was used for statistical analysis of the basic information of the patients included in the study and the denture restoration of the patients. RESULTS: The rate of postoperative denture restoration in the patients with mandibular defects repaired by free fibula flap was 17.5%, and the rate of postoperative denture restoration in the patients with benign mandibular tumors was 25.0% (18/72), which was significantly greater than that in the patients with malignant tumors 11.0% (9/82, P < 0.05). There was no significant difference in denture function score between the patients with condylar defect and those without condylar defect in denture repair rate and denture function score (P>0.05). The functional score of implant denture was significantly greater than that of removable denture (P < 0.05). According to Brown classification, the denture function score of the patients with the defect invo-lving the anterior mandibular region was significantly greater than that of the patients without the anterior mandibular region involved (P < 0.05). The poor oral conditions, such as less amount of remaining teeth, insufficient retention strength, large mobility of soft tissue in the surgical area, poor oral vestibular groove condition became the main reason of not receiving denture restoration (37.86%). CONCLUSION: The denture rehabilitation of mandibular defect reconstructed with vascularized free fibula flap is closely rela-ted to pathological properties and oral conditions. The clinical outcome of implant denture has been confirmed effectively and it is a better choice for future denture restoration after mandibular reconstruction.

Comparative Study of Degree of Great Toe Movement after Complete and Partial Flexor Hallucis Longus Harvest in Free Fibula Flap.

Background The flexor hallucis longus (FHL) muscle is crucial in fine motor control of the great toe but the muscle is often sacrificed in free fibula flap (FFF) reconstruction. The aim of this study was to compare great toe movement between complete and partial FHL resection during FFF harvest to see if FHL can be left behind (without undergoing fibrosis) in situ when bulk is not required at the recipient site. Methods A prospective, cross-sectional, observational study was performed including patients undergoing FFF harvest over a 2-year period. Movement of great toe interphalangeal joint was recorded of operated and unoperated legs in patients undergoing partial and complete FHL harvest and data analyzed. Results There was a statistically significant ( p < 0.05) difference between the two groups of patients. Conclusion FHL can be safely left in situ in patients not requiring bulk at the recipient site as blood supply, nerve supply, and muscle function are not compromised in partial FHL harvest. Further image-based and dye-based studies are warranted.

A comparison of outcomes of locking versus non-locking plate fixation for the distal fibula fractures: a systematic review and meta-analysis.

PURPOSE: A locking plate (LP) or non-locking plate (NLP) can be used for distal fibula fracture fixation. However, the advantages of LP over NLP in patients with distal fibula fractures are not clear. In terms of indications, the role of the two plates probably differs; however, to draw comparative conclusions, we conceptualized this systematic review and meta-analysis of studies that directly compared the two plates, wherein both groups' indications and baseline parameters were similar. METHODS: An electronic literature search was performed using PubMed/Medline, Embase, Scopus, and Cochrane Library databases for studies comparing the LP versus NLP fixation for the lateral malleolus fracture. A total of 18 studies were included in qualitative and quantitative analysis. A subgroup analysis was performed for patients aged < 55 years and patients aged > 55 years. The statistical analysis was performed by Review Manager Software version 5.4.1. RESULTS: A meta-analysis of 4243 fractures was performed across 18 studies. The rate of fracture union and overall complication rates did not differ between the two fixation groups with an OR of 0.71 (95% CI 0.26, 1.96, p = 0.51 and 1.11 (95% CI 0.84, 1.47, p = 0.47, respectively. There is no difference in the reoperation rate due to minor or major complications between the two groups. There was no difference in functional outcome (MD -0.85, with 95% CI -5.63, 3.93, p = 0.73), but NLP has a shorter surgical duration (MD 3.0, with 95% CI 0.26, 5.75, p = 0.03). A leave-one-out sensitivity analysis performed for overall complications affected the final outcome of the meta-analysis. CONCLUSION: This meta-analysis demonstrates no clear benefit in selecting LP over NLP for the fixation of lateral malleolus fractures.

Reconstruction of oncologic upper extremity defects with fibula free flaps has high union rates and excellent functional outcomes.

BACKGROUND: Limb salvage has better functional outcomes than amputation in the upper extremity. This can however be challenging after bony tumor resections. METHODS: This is a retrospective case series of patients who underwent humerus, ulna, or radius reconstruction with a fibula free flap. Data were collected on demographics, oncologic history, surgical details, and complications. Functional outcome measures included the patient's ability to perform activities of daily living (ADL), presence of pain, and musculoskeletal tumor society (MSTS) score. RESULTS: Over a 25-year period, 38 reconstructions were performed. The flap success rate was 97.5%. Bony union was obtained in 19 of 19 (100%) forearm reconstructions and in 15 of 19 (79%) humerus reconstructions (p = 0.10). All 19 forearm reconstruction patients and 18/19 humerus reconstruction patients were able to perform ADLs with no pain or only occasional pain. The MSTS scores were not significantly different between the humerus and forearm cohorts (27.1 vs. 27.3, p = 0.68). Functional outcomes were significantly better in limbs that achieved union (p < 0.001). Recipient and donor site complications occurred in 10 (26.3%) and 5 (13%) patients, respectively. CONCLUSIONS: Oncologic upper-extremity reconstruction with fibula free flaps has excellent functional outcomes. Bone union is a predictor of superior limb function.

Lower leg reconstruction after resection of a squamous cell carcinoma on necrobiosis lipoidica with a pedicled fibula and an extended anterolateral thigh flap-a case report.

BACKGROUND: Extensive loss of soft tissue and bone due to neoplasia, trauma, or infection in extremities often leads to amputation. CASE PRESENTATION: We present the case of a 72-year-old female patient presenting with an extended cutaneous squamous cell carcinoma of the lower leg, developed on top of necrobiosis lipoidica. After achieving the R0 resection, a 26 × 20-cm soft tissue and 15-cm tibial bone defect resulted. The contralateral leg had been lost due to the same disease 18 years before. We achieved a successful reconstruction of the leg using a pedicled fibula transplantation, an extended anterolateral thigh perforator flap, and an internal fixation with plate and screws. Two years after the original surgery, the patient is relapse-free and mobile, with adequate function of the reconstructed foot. CONCLUSIONS: Our case presented a unique combination of pedicled fibula transplantation and free extended ALT perforator flap to reconstruct an extensive defect after resection of a rare cSCC on top of NL. In selected cases, the boundaries of limb salvage can be pushed far beyond the current standards of treatment.

Proximal fibular physeal stress injury: a known entity in an unusual location.

In the skeletally immature patient, physeal stress injury is a common diagnosis in repetitive stress injury; in this case, we present an atypical location of physeal stress injury of the bilateral proximal fibulae. There are multiple well-documented diagnoses of physeal stress injury involving the shoulder, elbow, wrist and tibia, often considered when patients present with the typical history of intensive sports training and pain exacerbated by repetitive movements. However, isolated proximal fibular physeal stress injury is either unusual or under-recognized and underreported. Although less common, proximal fibular physeal stress injury should be among the diagnostic considerations in active adolescents complaining of lower extremity pain as failure to identify this entity can lead to delayed care and preventable potential long-term musculoskeletal effects.

Reconstruction of complicated spinal tuberculosis with long-segment fibula transplantation: a case report.

BACKGROUND: Treating complex cases of spinal tuberculosis (STB) that involve multiple vertebral bodies and cause destruction of the spinal structure, kyphotic deformity, and acute nerve injury can be challenging. This report describes the course of treatment and 5-year follow-up of a complex case of multisegmental STB. CASE PRESENTATION: This report describes a case of tuberculosis affecting the vertebrae extending from thoracic 12 to lumbar 5 in a 60-year-old woman who suffered sudden paralysis in both lower extremities. The patient underwent emergency posterior paraspinal abscess clearance, laminectomy with spinal decompression. Partial correction of the kyphotic deformity via long-segment fixation from the T9 vertebral body to the ilium in a one-stage posterior procedure. The patient's neurological status was diagnosed as grade E on the American Spinal Injury Association (ASIA) scale after the one-stage operation. Following standardized 4-combination anti-tuberculosis drug therapy for three months in postoperative patients, the patient underwent two-stage transabdominal anterior abscess removal, partial debridement of the lesion and bilateral fibula graft support. One year after the two-stage operation, the patient's visual analog scale (VAS) score of back pain was 1 point, and the patient's erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels returned to normal. Five years after the second-stage operation, the Oswestry disability index (ODI) of patient quality of life was 14 points. There was a 4-degree change in the Cobb angle over five years. During the five-year follow-up period, the grafted fibula did not experience any subsidence. CONCLUSION: For patients with spinal tuberculosis and acute paralysis, it is essential to relieve spinal cord compression as soon as possible to recover spinal cord function. For lesions that cannot be debrided entirely, although limited debridement combined with anti-tuberculosis drug therapy has the risk of sinus formation and tuberculosis recurrence, it is much safer than the risk of thorough debridement surgery. In this case, an unconventional long-segment fibula graft, pelvis-vertebral support, was an effective reconstruction method.

Comparing donor site morbidity in osteocutaneous radial forearm versus fibula free flap for mandibular reconstruction.

PURPOSE: The osteocutaneous radial forearm free flap has gained popularity as a less morbid option for oromandibular reconstruction compared to the fibular free flap. However, there is a paucity of data regarding direct outcome comparison between these techniques. METHODS: Retrospective chart review of 94 patients who underwent maxillomandibular reconstruction intervened from July 2012-October 2020 at the University of Arkansas for Medical Sciences. All other bony free flaps were excluded. Endpoints retrieved encompassed demographics, surgical outcomes, perioperative data, and donor site morbidity. Continuous data points were analyzed using independent sample t-Tests. Qualitative data was analyzed using Chi-Square tests to determine significance. Ordinal variables were tested using the Mann-Whitney U test. RESULTS: The cohort was equally male and female, with a mean age of 62.6 years. There were 21 and 73 patients in the osteocutaneous radial forearm free flap and fibular free flap cohorts, respectively. Excluding age, the groups were otherwise comparable, including tobacco use, and ASA classification. Bony defect (OC-RFFF = 7.9 cm, FFF = 9.4 cm, p = 0.021) and skin paddle (OC-RFFF = 54.6 cm2, FFF = 72.21 cm2, p = 0.045) size were larger in the fibular free flap group. However, no significant difference was found between cohorts with respect to skin graft. There was no statistically significant difference between cohorts regarding the rate of donor site infection, tourniquet time, ischemia time, total operative time, blood transfusion, or length of hospital stay. CONCLUSIONS: No significant difference in perioperative donor site morbidity was found between patients undergoing fibular forearm free flap and osteocutaneous radial forearm flap for maxillomandibular reconstruction. Osteocutaneous radial forearm flap performance was associated with significantly older age, which may represent a selection bias.
