A PROSPECTIVE STUDY ON THE FUNCTIONAL OUTCOME OF PROXIMAL FIBULAR OSTEOTOMY IN GRADE 2 AND 3 MEDIAL COMPARTMENT ARTHRITIS OF THE KNEE.

Introduction: Osteoarthritis of the knee is a common musculoskeletal diseases affecting a major population in India. It can impact the individual's functions and activities of daily living. Total knee arthroplasty may raise controversy when treating the younger, athletic patient with arthritis. Arthroscopic debridement, high tibial osteotomy, unicondylar knee arthroplasty, and total knee arthroplasty allow younger patients to maintain an active, healthy lifestyle but can take a longer time to rehabilitate. PFO could be used as an alternative procedure. The Proximal Fibular Osteotomy, which provides immediate short term relief in cases with medial compartment osteoarthritis. Resecting a segment of fibula, loosens the lateral side allowing the upper tibia to settle into a more favorable lateral alignment, shifting the mechanical axis towards neutral or valgus. Aims & objectives: Ÿ To assess the functional, clinical and radiological outcome of proximal fibular osteotomy in grade 2 and 3 OA of knee and followed up for 1 year. Ÿ The clinical and functional outcome is accessed by Knee Society Score and VAS observed pre-op , post-op ,3 months ,6 months and 12 months. Ÿ The improvement in radiology is accessed using change in the medial joint space improvements in CP angle, change in the ratio of medial joint space to lateral joint space observed pre-op and post-op Methodology: The patients selected had grade 2 and 3 Osteoarthritis of knee according to Kellgren Lawrence classification between the age groups 20yrs-80yrs and are admitted to RajaRajeswari Medical College and Hospital, Bangalore. The Sample Size is 30 and is calculated based on previous studies as well as approximate availability of number of cases in the above mentioned duration satisfying inclusion and exclusion criteria. Clinical, functional and radiological outcome were used, Results were calculated using Knee Society Scoring Scale score. This study Conclusion: suggested that Proximal Fibular Osteotomy is an alternative procedure that can be used to treat medial compartment knee Osteoarthritis, if the patients are selected carefully. Patients followed up for one year showed a significant improvement in radiological, clinical and functional outcomes and thereby is an effective method of treatment in younger patients with Grade 2 and Grade 3 Osteoarthritis with an average BMI of 26.2.

Enfermedad ultrarara frecuente en Perú: Reporte de casos del síndrome FATCO

El síndrome FATCO (fibular aplasia, tibial camptomelia, oligosyndactyly) está caracterizado por la presencia de anomalías en miembros inferiores. Es una enfermedad, de la cual no se ha precisado la etiología genética hasta la actualidad; sin embargo, se ha planteado que el tipo de herencia es dominante autosómica. La frecuencia de presentación a nivel global es muy rara y esta es la razón principal de los pocos pacientes publicados hasta la fecha. Existe un reporte de la presentación inusual de catorce pacientes peruanos, diagnosticados en un solo centro, con las características clínicas del síndrome FATCO en un período de 13 años. A la fecha, se han publicado catorce pacientes a nivel mundial, con los cuales se comparó y discutió los datos clínicos y radiológicos. Además, se analizaron las características demográficas, antecedentes familiares, sexo, edad y anomalías concomitantes.

The fibular aplasia, tibial campomelia, oligosyndactyly (FATCO) syndrome is characterized by the variable leg anomalies. The genetic etiology of this disease has not been determined to date; however, it has been suggested that the genetic inheritance is autosomal dominant. The frequency of presentation globally is infrequent and this is the main reason for the low number of patient reports. There's a report of the unusually high presentation of 14 peruvian patients diagnosed at a single center with the clinical features of FATCO syndrome over a 13-year period. We compare and discuss the clinical and radiological data of our patients with those of the 14 cases described worldwide. In addition, the demographic characteristics, family history, sex, age, and concomitant anomalies are analyzed.

Hemangioma of the mandible in a 12-year-old boy

@#Intraosseous hemangioma is a benign, rare neoplasm that accounts to 0.5 - 1% of all benign tumors of bones.1, 2 While most hemangiomas arise from soft tissues, it is uncommon for it to arise from bones.2 The most common sites of growth are in the vertebral body and the calvarium with frontal bone making up approximately 45% of calvarial cases.2,3 However, they are also encountered in the head and neck with sites such as the skull (53%), mandible (10.7%), nasal bones (9%), and cervical spine (6%).4 In the mandible, the body is mostly affected and 65% are found in the molar and premolar region.1 They are more common in adult females with peaks at the second and fifth decades of life.1-3 Hemangioma of the mandible is difficult to diagnose due to its nonspecific clinical presentation and radiographic features. It mimics various mass lesions in the mandible such as giant cell granuloma, fibrous dysplasia, multiple myeloma, osteosarcoma, ameloblastoma and keratocysts. Therefore, a comprehensive history taking and physical examination plus examination of the imaging studies available and tissue biopsy all play important roles in arriving at the final diagnosis.5 We present the case of an aggressive mandibular hemangioma in a young boy and our management involving a failed fibular free flap reconstruction.

A CASE REPORT ON SALVAGE OF FAILED INTERNAL FIXATION OF PROXIMAL HUMRUS FRACTURE USING FIBULAR STRUT GRAFT.

Proximal humerus fractures are common problems plaguing in geriatric population. Approximately half of all proximal humeral fractures occur due to fall usually at ground level. (Low velocity trauma). In younger individuals fractures occurring because of higher-energy trauma such as a fall from a height, motor vehicle accidents, sports, or assaults. The proximal humerus fracture because of three loading modes: compressive loading of the glenoid onto the humeral head, bending forces at the surgical neck, and tension forces of the rotator cuff at the greater and lesser tuberosities. Most proximal humeral fractures are treated nonoperatively. However, surgical treatment is becoming more popular, with development of modern implant (PHILOS plate). Implant failure is common complication occur due to improper fixation, osteoporotic bone, early mobilization, non-union and varus malalignment. Various modality available for its management i.e., Hemiarthroplasty, reverse shoulder arthroplasty and ORIF + bone graft. IN this case report 60-year male patient with right side proximal humerus fracture treated with PHILOS plating. At 6 week follow up radiograph suggest implant failure. Patient was posted for revision surgery ORIF + platting and fibular strut graft was done.

Supernumerary muscles in the posterior leg compartment: a case report / Músculos supernumerarios en el compartimento posterior de la pierna: reporte de un caso

SUMMARY: The leg muscles are organized in anterior, lateral and posterior compartments. The posterior compartment is usually divided in two layers: superficial and deep. The deep muscles of the posterior compartment of the leg are known to mainly plantar flexion and toes flexion. In comparison to the other leg compartments, variations of the posterior one are rare. These variants often involve the presence or absence of one or more muscles, and they have differences among origin and insertion, which leads to confusion between anatomists. We aim to describe a case of a male cadaver that possessed three supernumerary muscles in the lateral and posterior compartments of both legs: the peroneus quartus muscle and two accessory bellies of the flexor digitorum longus. This presentation seems to be very rare and scarcely reported in the literature. These variants have the potential of causing nervous or vascular compression, thus leading to tarsal tunnel syndrome or a symptomatic peroneus quartus. The clinical and surgical implications of this abnormal presentation is discussed.

RESUMEN: Los músculos de la pierna están organizados en compartimentos anterior, lateral y posterior. El compartimento posterior por lo general es dividido en dos capas: superficial y profunda. Se sabe que los músculos profundos del compartimento posterior de la pierna se caracterizan principalmente por participar de la flexión plantar y la flexión de los dedos de los pies. En comparación con los otros compartimentos de la pierna, las variaciones musculares en el compartimiento posterior son raras. Estas variantes suelen implicar la presencia o ausencia de uno o más músculos y presentan diferencias en el origen y en la inserción, lo que conduce a confusión entre los anatomistas. Nuestro objetivo fue describir el caso de un cadáver masculino que poseía tres músculos supernumerarios en los compartimentos lateral y posterior de ambas piernas: el músculo fibular cuarto y dos vientres accesorios del músculo flexor largo de los dedos. Esta presentación parece ser muy rara y escasamente reportada en la literatura. Estas variantes musculares tienen el potencial de causar compresión nerviosa o vascular, lo que conduce al síndrome del túnel del tarso o un cuarto músculo fibular sintomático. Se discuten las implicaciones clínicas y quirúrgicas de esta presentación anormal.

Proximal tibiofibular stabilization by anatomical ligamentoplasty and diaphyseal osteotomy of the fibula / 中华创伤杂志(英文版)

Proximal tibiofibular instability is a rare condition for which treatment is poorly codified. A 21-year-old patient, a leisure sportswoman, presented a post-traumatic anterolateral instability of the proximal tibiofibular articulation without cartilage lesion. We propose an original surgical technique based on a review of the literature that combines an anatomical ligamentoplasty of the proximal tibiofibular joint and a proximal fibular diaphyseal osteotomy to reduce the distal tibiofibular mechanical stresses. This original technique allows a favorable evolution with recovery of professional and sports activities at 6 months.

Reconstruction of multiple metatarsus and soft tissue defects with fibular flap and fibular artery chimeric: A case report / 中华显微外科杂志

In May 2019, a patient who suffered with multiple foot metatarsus injury with soft tissues defect was treated in the Hand and Foot Microsurgery of Xi'an Fengcheng Hospital, by using chimeric peroneal artery for phase-1 reconstruction of metatarsus with folded fibular flap, foot cross arch and soft tissue defects. After 2 years, the arch of foot as intact without collapse. There was no arthritic lesions. The height, arc and width of metatarsus were very close to the healthy side. The flap and plantar were smooth without abrasion and ulceration. The patient could walk, run and stand with single-foot stand, and able to carry out heavy physical work continuously.

Clinical research of ankle fusion with vascularised semi-split fibular flap via lateral approach / 中华显微外科杂志

Objective:To investigate the clinical efficacy of the vascularised semi-split fibular flap with lateral approach in ankle fusion.Methods:A total of 54 patients who underwent ankle fusion through the lateral menstrual approach by the Department of Trauma and Micro Orthopaedics, Zhongnan Hospital of Wuhan University from June 2015 to December 2020 was retrospectively analysed. Of the 54 patients, 27 patients who underwent ankle fusion with a semi-split fibular flap carrying blood supply were assigned to the fibular flap group, while other 27 patients who had ankle fusion with lateral plate were assigned to the plate group. The ankle fusions for both groups were performed by the same surgical team. The clinical efficacy of the 2 groups was evaluated by the success rate of bone fusion, the American Orthopedic Foot and Ankle Surgery(AOFAS) Ankle-Hindfoot Score System, and the Visual analog score(VAS). All the patients entered the postoperative follow-up at outpatient clinic.Results:The follow-up lasted for 12-24 months, with an average of 15 months. At 6 months after surgery, 24 patients in the fibular flap group achieved osseous union with 88.9% in the success rate of bone fusion. While 17 patients in the plate group achieved osseous union, with the success rate of bone fusion at 63.0%. There was a statistically significant difference between the groups( P<0.05). At 1 year after surgery, all 27 patients in the fibular flap group achieved bony union, with a 100% of the success rate of bone fusion, while 23 patients in the plate group achieved bony union at a 85.2% success rate of bone fusion, with 4 patients failed to heal. The difference was statistically significant( P<0.05). The AOFAS scores of the fibular flap group were 41.3±12.0, 65.6±5.6, and 79.1±7.0 before operation, at 6 months after operation and 1 year after operation, respectively, while the scores for the plate group at the same time were 40.8±11.3, 64.5±4.1 and 69.3±7.2. There was no significant difference in the scores between the groups before surgery and at 6 months after the operation ( P>0.05). The scores at 1 year after surgery in the fibular flap group was significantly higher than the plate group, and there was a statistically significant difference( P<0.05). The preoperative VAS score in the fibular flap group was 7.6±1.3, while it was 7.5±1.1 in the plate group. There was no significant difference between the groups in VAS score( P>0.05). However, the VAS score at 1 year after surgery was found at 1.8±0.9 in the plate group, and 1.9±0.8 in the fibular flap group and the difference between groups was statistically significant( P<0.05). Conclusion:The surgical procedure of semi-split fibular flap through the lateral approach has lower complications and higher success rate in ankle fusion in comparison with those of the fusion with lateral plate. Thus, further clinical investigations can be considered.

Objective:To explore the clinical application and effect of repairing the donor site of ipsilateral fibular hallux flap with the transverse V-Y advancement flap of the great toe.Methods:Form January 2017 to January 2020, the donor sites of the ipsilateral fibular hallux flap were repaired by the transverse V-Y advancement flap of the great toe in the Department of Hand Surgery, 521 Hospital of Weapon Industry on 20 patients, including 16 males and 4 females with an average age of 33 (18-52) years old. First, the donor site of the fibular hallux flap was sutured to reduce the size of wound. The width of the remaining wound was 0.4 to 1.6 cm, and the area of the remaining wound was 0.5 cm×0.8 cm-1.6 cm×1.8 cm. Then the remaining wound was repaired with the transverse V-Y advancement flap of the ipsilateral great toe. The distance for transfer of transverse advancement V-Y flap was 0.2-0.8 cm, and the area of the transverse V-Y advancement flap was 1.0 cm×1.4 cm-1.8 cm×2.4 cm. The end of postoperative follow-up was scheduled in July 2021. The follow-up items included: survival of the transverse V-Y advancement flap, wound infection, appearance, shape, texture and sensation of the V-Y advancement flap, pain on the V-Y advancement flap and the great toe, cold tolerance and the scar condition at the donor site of the ipsilateral fibular hallux flap and the V-Y advancement flap, the appearance, sensation and flexion and extension of the great toe at the donor site, other discomforts in the donor site of great toe, walking and other functions affected by the discomforts.Results:The postoperative follow-up lasted from 12 to 18(average of 14) months. All the V-Y advancement flaps survived without infection at the donor sites of the great toe, and donor sites healed primarily. The appearance, shape and texture of the advancement V-Y flap were close to the skin of the same area of the contralateral great toe. The TPD of the V-Y advancement flap and the ipsilateral great toe ranged from 4 to 7 mm. The average score of the Visual analog scale(VAS) was 0.3 and 0.6 respectively in the evaluation of cold tolerance of the advancement V-Y flap and the ipsilateral great toe. The average score of the Vancouver scar scale(VSS) was 0.2 and 1.2 respectively in the scar evaluation of the V-Y advancement flap and the ipsilateral great toe. There was no visual difference between the appearance of the great toe at the donor site and the contralateral toe. There was no pain and other discomfort on the V-Y advancement flap and the ipsilateral great toe. The functions of the donor foot were not affected in walking, running, jumping and tiptoeing in all cases.Conclusion:It is a simple, safe and effective method to repair the donor site of the small-area ipsilateral fibular hallux flap by the transverse V-Y advancement flap of the great toe. It only causes a small wound but the appearance and function of the ipsilateral great toe can be repaired with a transverse V-Y advancement flap of the great toe.

Objective:To investigate the clinical effect of free fibular flap of great toe without vein in repairing soft tissue defect of finger pulp.Methods:From June 2020 to January 2021, 8 cases of finger pulp soft tissue defect were repaired with free flap of fibular side of great toe without vein, including 6 males and 2 females, with an average age of 32(18-42) years old. The defect area of finger pulp was 1.0 cm×0.5 cm-1.8 cm×0.8 cm. The proper digital artery and digital nerve of the affected finger were anastomosed. All flaps did not carry reflux veins. The donor site of the toe was directly sutured. Postoperative routine anti infection, anti spasm and anticoagulant treatment was performed. Postoperative outpatient regular follow-up.Results:All flaps survived without vascular crisis, and the donor and recipient sites healed in the first stage. All patients were followed-up for an average of 6.4(4-12) months. At the last follow-up, the TPD was 6-8 mm, the hand function was evaluated according to the Trial Standard of Upper Limb Function Evaluation of Hand Surgery Society of Chinese Medical Association. Seven cases were excellent and 1 case was good.Conclusion:The free fibular flap of the great toe can be used to repair the small wound of finger pulp without carrying the draining vein, the flap can still survive. And it can provide a certain reference for the failure of anatomic separation of the draining vein.

Luxación tibiofibular proximal diagnóstico y tratamiento / Proximal tibiofibular joint dislocation diagnosis and treatment

Resumen: Introducción: La luxación tibiofibular proximal (LTFP) es una lesión poco frecuente y no diagnosticada. De no ser tratada a tiempo, puede generar una sintomatología crónica de dolor e inestabilidad. La escasa evidencia disponible no entrega un protocolo de enfrentamiento ni consenso respecto a su manejo. Con el objetivo de asistir al enfrentamiento de esta lesión, se presenta una revisión de la literatura de una LTFP con reducción espontánea. Caso clínico: Hombre de 22 años consulta por dolor intenso en su rodilla derecha, posterior a caída en cuatrimoto. Al examen físico con aumento de volumen doloroso en cara lateral de la rodilla y pierna proximal, con movilidad completa y estable. Radiografías son informadas sin alteraciones. Se mantiene la sospecha clínica de LTFP, se continúa estudio con resonancia magnética (RM), la que es sugerente de LTFP. Dentro de las 24 horas de evolución, el paciente indica haber sentido un clank espontáneo en su rodilla afectada con cese completo de sintomatología. Se sigue al paciente por tres meses con RM de control, manteniendo una rodilla asintomática; examen físico y funcionalidad normal. Conclusión: El diagnóstico de las LTFP requiere un adecuado uso de imágenes. Su manejo consiste en una reducción cerrada de urgencia y de no lograrse, una reducción abierta, reparación y fijación interna. El pronóstico de las reducciones espontáneas es incierto, por lo que deben ser seguidas de forma seriada y en caso de recidiva, manejadas quirúrgicamente según el tiempo de evolución.

Abstract: Introduction: Proximal tibiofibular joint dislocations (PTFJD) are uncommon and underdiagnosed injuries. Urgent reduction is mandatory to avoid chronic disfunction. The scarcely available literature does not present a unified management guideline. An acute PTFJD case report with spontaneous reduction and a review of the literature is presented, aiming to assist the diagnosis and management of this pathology. Case report: A 22-years old male presented to the emergency department with high intensity right knee pain after falling in a four-wheel motorcycle. The physical exam revealed a prominent painful mass on the lateral aspect of his knee and proximal leg. His range of motion and knee stability were unremarkable. X-rays were informed negative for musculoskeletal injuries. According to a sustained suspicion of PTFJD, the study was continued with a magnetic resonance imaging (MRI), which suggested PTFJD. During the following 24 hours, the patient referred he was entirely asymptomatic after feeling a loud «clank¼. He has been followed for three months with MRI, and remains asymptomatic with full functions. Conclusion: PTFJD diagnosis requires appropriate images. Urgent close reduction is mandatory; if unsuccessful, open reduction, primary repair and internal fixation are indicated. The prognosis of spontaneous reduction remains uncertain and requires a serial clinical evaluation. In the case of recurrence, the appropriate surgical management is indicated according to the elapsed time from the injury.

Magnetic resonance imaging evaluation of common peroneal nerve injury in acute and subacute posterolateral corner lesion: a retrospective study / Estudo retrospectivo das alterações do nervo fibular comum identificadas por ressonância magnética nas lesões agudas e subagudas do canto posterolateral do joelho

Abstract Objective: To evaluate qualitative and quantitative magnetic resonance imaging (MRI) criteria for injury of the common peroneal nerve (CPN) in patients with acute or subacute injuries in the posterolateral corner (PLC) of the knee, as well as to evaluate the reproducibility of MRI evaluation of CPN alterations. Materials and Methods: This was a retrospective study of 38 consecutive patients submitted to MRI and diagnosed with acute or subacute injury to the PLC of the knee (patient group) and 38 patients with normal MRI results (control group). Two musculoskeletal radiologists (designated radiologist A and radiologist B, respectively) evaluated the images. Nerve injury was classified as neurapraxia, axonotmesis, or neurotmesis. Signal strength was measured at the CPN, the tibial nerve (TN), and a superficial vein (SV). The CPN/TN and CPN/SV signal ratios were calculated. The status of each PLC structure, including the popliteal tendon, arcuate ligament, lateral collateral ligament, and biceps tendon, was classified as normal, partially torn, or completely torn, as was that of the cruciate ligaments. For the semiquantitative analysis of interobserver agreement, the kappa statistic was calculated, whereas a receiver operating characteristic (ROC) curve was used for the quantitative analysis. Results: In the patient group, radiologist A found CPN abnormalities in 15 cases (39.4%)-neurapraxia in eight and axonotmesis in seven-whereas radiologist B found CPN abnormalities in 14 (36.8%)-neurapraxia in nine and axonotmesis in five. The kappa statistic showed excellent interobserver agreement. In the control group, the CPN/TN signal ratio ranged from 0.63 to 1.1 and the CPN/SV signal ratio ranged from 0.16 to 0.41, compared with 1.30-4.02 and 0.27-1.08, respectively, in the patient group. The ROC curve analysis demonstrated that the CPN/TN signal ratio at a cutoff value of 1.39 had high (93.3%) specificity for the identification of nerve damage, compared with 81.3% for the CPN/SV signal ratio at a cutoff value of 0.41. Conclusion: CPN alterations are common in patients with PLC injury detected on MRI, and the level of interobserver agreement for such alterations was excellent. Calculating the CPN/TN and CPN/SV signal ratios may increase diagnostic confidence. We recommend systematic analysis of the CPN in cases of PLC injury.

Outros 38 pacientes com RM normal foram utilizados como grupo controle. Dois radiologistas musculoesqueléticos (A e B) analisaram as imagens. A lesão neural foi classificada em neuropraxia, axoniotmese ou neurotmese. Foi medida a intensidade do sinal no NFC, no nervo tibial (NT) e em uma veia superficial (VS), e calculadas as razões de sinal NFC/NT e NFC/VS. Estruturas do CPL, incluindo tendão poplíteo, ligamento arqueado, ligamento colateral lateral e tendão do bíceps, foram classificadas como normal, rotura parcial ou rotura completa. Os ligamentos cruzados também foram avaliados segundo os mesmos critérios. O teste kappa foi utilizado para avaliar a concordância interobservador para as classificações semiquantitativas. Curva ROC foi utilizada para análise quantitativa. Resultados: O radiologista A encontrou alterações no NFC em 15 casos (39,4%): 8 neuropraxias, 7 axoniotmeses e nenhuma neurotmese. O radiologista B encontrou alterações no NFC em 14 casos (36,8%): 9 neuropraxias, 5 axoniotmeses e nenhuma neurotmese. O teste kappa mostrou alta concordância interobservador. No grupo controle, a razão NFC/NT variou entre 0,63-1,1 e a razão NFC/VS variou entre 0,16-0,41. Para o grupo de pacientes, a razão NFC/NT variou entre 1,30-4,02 e a razão NFC/VS variou entre 0,27-1,08. A análise com curva ROC demonstrou alta especificidade (93,3%) com relação à razão NFC/NT, usando um valor de corte de 1,39. Houve boa especificidade (81,3%) para a razão NFC/VS usando um valor de corte de 0,41. Conclusão: As alterações do NFC são detectadas com frequência nas lesões do CPL nas imagens de RM, com concordância interobservadores quase perfeita. Usando as razões de intensidade de sinal entre o NFC e o NT e entre o NFC e a VS, aumenta a confiança no diagnóstico. Recomendamos a análise sistemática do NFC nos casos de lesão do CPL.

Comparison of the effect of perforator flap of proper palmar digital artery and hallex fibular flap in repair of soft tissue defect of fingers / 中华显微外科杂志

Objective:To compare the clinical effect of perforator flap of proper palmar digital and hallex fibular flap in repair of soft tissue defect of fingers.Methods:A total of 52 patients with finger soft tissue injury were reviewed from January, 2017 to January, 2019. Twenty-seven patients were repaired by perforator flap of proper palmar digital artery, and 25 by hallex fibular flaps. Both groups of patients had only soft tissue defects without phalangeal fracture. Postoperative follow-up were conducted by phone, WeChat and visit of outpatient clinic. The recovery of finger sensory function was evaluated according to the Trial Standard for Replantation Evaluation of Severed Digit by the Hand Surgery Society of Chinese Medical Association. The flaps were evaluated according to the shape, patient satisfaction and finger function and classified in excellent, good, fair and poor. Data of the 2 groups of patients were collected and statistically analysed by SPSS 22.0. P<0.05 was statistically significant. Results:Both groups entered follow-up for 12-16 months. All flaps in both groups survived. There was statistically significant difference of TPD between the 2 groups[TPD were 4-7(5.3±1.2) mm and 6-10(8.4±1.7)mm, respectively]( t=7.642, P=0.000). According to the Evaluation Criteria of the Hand Surgery Society of the Chinese Medical Association. In the group repaired by perforator flap of proper palmar digital artery, 17 fingers were excellent, 6 good, and 4 fair, with a 85.1% of excellent and good rate. In the group repaired by hallex fibular flap, 8 fingers were excellent, 5 good, 9 fair, and 3 poor, with a 52.0% of excellent and good rate. The difference between 2 groups was statistically significant ( t=6.710, P=0.009). There was a 3.7% incidence of complications in the group repaired by perforator flap of proper palmar digital artery, and 25.9% in the group repaired by hallex fibular flap. The difference between the 2 groups was statistically significant( t=4.167, P=0.032), and there was a higher incidence of complications in the group repaired by hallex fibular flap. Conclusion:The perforator flap of proper palmar digital artery and the hallex fibular flap are good choices in the repair of finger soft tissue defect. However, the postoperative complication of the hallux fibular flap is relatively high. Therefore, it is necessary to make a decision in the choice of flap according to the actual situation in clinical work.

Application of fibular flap with partial continuous periosteum and cortex in hip preservation surgery for femoral head necrosis / 中华显微外科杂志

Objective:To investigate the short-term clinical effect of using fibular flap with preserving the continuity of fibula in hip preservation surgery for femoral head necrosis.Methods:From September, 2017 to November, 2020, 13 cases of femoral head necrosis were repaired with fibular flap. The fibular flaps were cut with an improved method for preserving the continuity of the fibular cortex, and the donor sites were sutured directly. The fibuls were inserted into the femoral heads with single or double segment folding support. Autogenous iliac crest combined with platelet-rich plasma(PRP) was used for impaction of bone grafting in femoral head, and the fibular flaps were anastomosed with 1 artery and 2 veins. All follow-up data were obtained, including bone union by X-ray and CT as well as the functional recovery of the hip joint and donor site. Statistical analysis was performed. P<0.05 was considered statistically significant. Results:The followed-up time ranged from 6 to 23 months. The fibular bones were significantly thicker and the incisions healed well at the donor sites. There was neither abnormal sensation in toes, dorsal foot, and lateral of the leg, nor significant influence on foot function. The hip joint activities were normal. The outcome was proved to be remarkable according to the Harris score(from 58.9±10.6 points before surgery to 81.7±10.6 points after surgery), the difference was statistically significant ( P<0.05) . Conclusion:The method of the improved fibular flap in hip preservation surgery is beneficial to the repair and reconstruction of the necrotic femoral head since the donor area is less traumatic, and a satisfactory clinical effect can be obtained.

Functional outcome in patient with giant cell tumour distal radius after reconstruction by en-bloc resection and non-vascularized fibular bone graft: a case report

Giant cell tumor (GCT) is a relatively common benign primary bone tumor, commonly seen in end of long bones. Treatment goals for GCT of the distal radius are complete excision of the tumor and preservation of wrist function. Usually it can be treated by en-bloc resection and reconstruction using autogenous non vascularized ipsilateral proximal fibular graft. Authors present a case of twenty two years old female complaining of pain and lump in left wrist since two years ago. The pain worsened since 1 month before consultation, but did not radiate elsewhere. Pain was aggravated by movement and decreased with rest. Physical examination revealed a 3 cm mass with tenderness over left wrist. With clinical suspicion of benign bone tumor on left wrist, further evaluation was needed. Plain radiograph revealed an expansile, lytic lesion and soap bubble appearance on her left distal radius like a GCT. Open biopsy result revealed similar morphology with GCT. Reconstruction by en-bloc surgical excision, followed with non-vascularized fibular bone graft fixed with dynamic compression plate (DCP) and wrist ligament reconstruction and fixation of the head of the fibula with carpal bones and distal end of the ulna using K-wires along with palmaris longus tendon were performed. En-bloc resection of giant cell tumors of the lower end radius is a widely accepted method. Reconstruction with non-vascularized fibular graft, internal fixation with DCP with trans fixation of the fibular head and wrist ligament reconstruction minimizes the problem and gives satisfactory functional results.

Comparison outcome in management of femoral neck fracture using multiple cancellous screws with and without fibular graft

Multiple cancellous cannulated screw is preferred method in fresh cases of fracture neck of femur in young patients. Fibular strut graft is sometimes used along with multiple cancellous cannulated screws to enhance union and early restoration of function. We conducted a retrospective study to patients aged between 20-50 years old with femoral neck fracture treated with multiple cancellous screws either with or without fibular graft between the period of January 2016 to January 2018. We obtained total of six patients (five males and one female) with femoral neck fracture treated with multiple cancellous screws either with or without fibular graft. All fractures were garden type II-IV fresh femoral neck fractures. The functional outcome based on Harris hip score was excellent for all patients. The mean time of full weight bearing was 16±8 weeks in both multiple cancellous screws without fibular group and multiple cancellous screws with fibular group. The mean time of union was also 16±8 weeks in both groups. There is no complication such as non-union, avascular necrosis of femoral head and/or broken fibular graft in both the groups occurrences. Fixation with cancellous screws and fibular strut grafts for femoral neck fractures is cost effective and technically less demanding and associated with good outcomes. There is no added advantage of non-vascularized fibular grafting with multiple hip screw fixation in fresh femoral neck fractures in young adults over multiple hip screw fixation alone.

To Study the Functional Outcomes of Proximal Fibular Osteotomy in Osteoarthritis Kee

Introduction: Knee osteoarthritis (OA), also known asdegenerative joint disease, is typically the result of wearand tear and progressive loss of articular cartilage leadingto radiologically decreased joint space. Proximal fibularosteotomy (PFO) is an alternative treatment to high tibialosteotomy (HTO). Hence; under the light of above mentioneddata, the present study was undertaken for assessing thefunctional outcomes of proximal fibular osteotomy inosteoarthritis knee.Material and methods: A total of 10 patients with OA ofknee were enrolled in the present study. The patients wereplaced in the supine position after administration of spinalanaesthesia. An approximately 5-cm longitudinal incisionwas made over the lateral aspect of the proximal fibula, andthe fibula exposed between the peroneus muscle and soleusmuscle. PFO was performed under the hands of skilled andexperienced orthopaedic surgeon. Knee pain was assessedusing a Visual analogue scale. Knee ambulation activitieswere recorded using the knee and function subscores of theAmerican Knee Society score (KSS). All the results wererecorded in Microsoft excel sheet and were analyzed by SPSSsoftware. Chi- square test and Mann Whitney U test were usedfor assessment of level of significance.Results: Mean KSS score at pre-operative, postoperative,postoperative 6 weeks and postoperative 9 months werefound to be 44.03, 53.50, 58.60 and 68.14 respectively.Significant results were obtained while comparing the meanKSS at different postoperative time intervals. In the presentstudy, mean VAS score at pre-operative, postoperative,postoperative 6 weeks and postoperative 9 months were foundto be 8.77, 6.96, 4.36 and 2.52 respectively. Significant resultswere obtained while comparing the mean VAS at differentpostoperative time intervals.Conclusion: PFO is a novel alternative method in themanagement of medial compartment arthritis of the knee.
