Transfibular ankle arthrodesis with use of sagitally split fibula as a biological plate leads to excellent outcome: A retrospective analysis

BackgroundWe studied ankle arthrodesis with a transfibular approach using sagitally spilitted fibula as a biological plate (onlay grafting) as well as other half of fibula as morcellised local interpositional graft (inlay grafting) to achieve bony union.Material and methodsRetrospective clinico-radiological evaluation of 36 operated cases was done at 3, 6, 12 and 30 months follow-ups. Clinically union was considered once ankle became pain free on full weight bearing. Pain assessment was done by using VAS (visual analogue scale) score and functional evaluation was done by AOFAS (American Orthopaedic Foot & Ankle Society) hind foot score preoperatively and at different follow ups. Radiologically, sagittal plane ankle alignment and fusion status was determined at each follow up.ResultsMean age of patients was 40.36 ± 10.56 years (range 18–55), who were evaluated for mean duration of 33.32 ± 11.25 months (range 24–65). Thirty-three (91.7%) ankles were fused adequately and mean duration to achieve bony union was 5.09 ± 1.3 months (range 4–9 months). Mean post-operative AOFAS score at final follow up was 76.65 ± 4.87 in comparison to 45.76 ± 3.38, preoperatively. VAS score improved significantly from 7.8 (pre-operative) to 2.3 (final follow-up). Non-union in three patients (8.3%) and ankle malalignment in one patient was observed.ConclusionTransfibular ankle arthrodesis achieves excellent bony unions and functional outcomes in severe ankle arthritis. Biologically incompetent fibula that to be judged individually by the operating surgeon to use it as a graft. Patients having inflammatory arthritis have more dissatisfaction than other aetiologies.     

Modified Blair ankle fusion for ankle arthritis

Objective： To investigate the clinical outcome of modified Blair ankle fusion for ankle arthritis. Methods： Between November 2009 and June 2012, 28 patients with ankle arthritis were treated, among whom 11 had obvious foot varus deformity, and 17 were almost normal in appearance. There were 13 males and 15 females with an average age of 49.4 years （range, 23-67 years）. The main symptoms included swelling, pain, and a limited range of motion of the ankles. The ankle joints functions were assessed by American Orthopedic Foot and Ankle Society （AOFAS） ankle and hindfoot score and visual analog scale （VAS） preoperatively and at I year follow-up. Results： Twenty-eight patients were followed up for 19.8 months on average （range, 1-2 years）. Superficial wound infection occurred in 3 cases, and was cured after debridement; the other incisions healed by first intention without complications. All ankles were fused at 1 year follow-up after operation. The symptom was relieved completely in all patients at last follow-up without complication of implant failure, or nonunion. The postoperative AOFAS ankle and hindfoot score was 83.13±3.76, showing significant difference when compared with the preoperative score （45.38±3.21, P〈0.01）. VAS was significantly decreased from 8.01±0.63 to 2.31±1.05 at 1 year follow-up （P〈0.05）. Conclusion： Modified Blair ankle fusion has the advantages of high feasiblity, less cost and rigid fixation. It shows high reliability in pain relief and may obtain a good clinical effectiveness.

Supramalleolar Osteotomy With Distraction Arthroplasty in Treatment of Varus Ankle Osteoarthritis With Large Talar Tilt Angle: A Case Report and Literature Review

We treated a 57-year-old female with modified Takakura stage 3B varus ankle osteoarthritis. Her preoperative talar tilt angle was 21.3°. The patient wished to avoid ankle joint arthrodesis or replacement. Therefore, medial opening wedge supramalleolar osteotomy with fibular osteotomy was used for her varus ankle osteoarthritis. Also, fixed medial distraction arthroplasty was performed to improve her talar tilt. After 3 months, the external device was removed, and the patient was allowed partial weightbearing and began full weightbearing 4 months postoperatively after the osteotomy site had reached bony union radiographically. At the 3-year follow-up visit, a radiograph showed the medial ankle joint space enlargement had been maintained. The talar tilt angle had decreased to 3.3°, and the modified Takakura stage had improved to stage 1. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale score had improved from 26 points preoperatively to 85 points at 3 years postoperatively. Our findings suggested that good clinical and radiologic results can be achieved with supramalleolar osteotomy combined with distraction arthroplasty in the treatment of varus ankle osteoarthritis with a large talar tilt angle.     

踝关节骨折畸形愈合的重建手术

目的 总结踝关节骨折畸形愈合重建术的临床疗效.方法 2006年1月至2009年1O月,共收治23例踝关节陈旧性骨折畸形愈合患者.男14例,女9例;平均年龄45岁(21～69岁).初次受伤至最终重建术平均间隔18个月(12～36个月),其中11例患者曾接受切开复位内固定术.术前常规行X线及CT检查,对畸形进行个体化评估:所有患者均有不同程度的腓骨短缩或旋转,合并内、外翻畸形者4例,下胫腓联合间隙增宽者5例.对所有腓骨短缩或旋转的患者行腓骨延长截骨术,内外翻畸形则行开放或闭合楔形截骨,而下胫腓增宽者则须行下胫腓功能性融合.术后定期行影像学随访评估骨愈合情况,记录并发症发生情况,并采用美国骨科足踝外科协会(American Orthopedic Foot Ankle Society,AOFAS)踝关节与后足功能评分来评估治疗效果.结果 共21例患者获随访,平均随访36个月(12～58个月).所有随访患者均无感染、内固定失败、骨不连、畸形复发等发生.影像学随访显示于术后平均12周(10～14周)骨愈合,且力线恢复良好.AOFAS踝关节与后足功能评分从术前平均28分(15～39分)改善为术后1年平均82分(70～94分).2例患者因严重创伤性关节炎分别于术后18个月和术后2年行踝关节融合术.结论 对于踝关节骨折畸形愈合的患者,通过早期重建手术恢复腓骨长度和旋转及踝穴的匹配,踝关节功能可获得极大的改善,也可延缓创伤性关节炎的发展.

Abstract：

Objective To summarize the clinical outcomes of reconstruction of malunited ankle fractures.Methods From January 2006 to October 2009,23 malunited ankle fractures were treated in our department.All deformities were evaluated individually based on pre-operatively X-ray and CT scan.Varying degrees of fibular shortening or rotational deformity were found in all patients,with 4 cases of varus or valgus deformity,and 5 of a widen syndesmosis.Then different reconstructive techniques were chosen according to the type of malunion:a lengthening fibular osteotomy was performed in patients with fibular shortening or rotational deformity;an opening or closing wedge osteotomy was chosen correspondingly in patients with varus or valgus deformity;functional fusion of syndesmosis was performed in cases of widen syndesmosis.The postoperative follow-up included standard radiography to evaluate bone union;relative complications were also recorded and functional outcome were assessed with American Orthopedic Foot Ankle Society (AOFAS)ankle-hindfoot scores.Results Twenty-one patients were followed up with an average period of 36 months (12-58 months).There were no complications of infection,implant failure,nonunion or malunion.Solid union with a favorable alignment was obtained at an average of 12 weeks (10-14 weeks).The mean pre-operative AOFAS ankle-hindfoot score was 28 (15-39).While the score increased to 82 (70-94) one year after operations.But 2 patients underwent ankle arthrodesis correspondingly 18 months and 24 months post-operatively due to severely post-traumatic arthritis.Conclusion An early realignment reconstruction of the length and rotation of fibula and the congruity of ankle mortise may improve the ankle function and slow down the development of post-traumatic arthritis for patients who suffered from malunited ankle fractures.     

Obtaining Correct Ankle Alignment Using Intraoperative External Fixation for Ankle Arthrodesis

Ankle arthrodesis remains an important treatment option for patients with ankle arthritis. Many methods have been described; however, no consensus has been reached regarding the best technique to achieve both successful fusion and a good position for optimal foot mechanics. Furthermore, as arthroplasty has become more popular, preservation of the fibula to allow for future arthroplasty has become critical. The present report describes an innovative technique in which temporary external fixation at operative fixation is used, along with internal fixation, to achieve both an optimal foot position and high fusion rates, while maintaining the integrity of the fibula. Seventeen patients were identified who met the criteria for inclusion. Their medical records, including pre- and postoperative radiographs, were reviewed retrospectively. Preoperative and postoperative coronal and sagittal alignment was determined. All patients achieved successful fusion, although 1 (5.9%) patient experienced delayed union. The average tibial/talar ratio preoperatively was 21% (range 8% to 33%), demonstrating anterior subluxation. Postoperatively, this ratio improved to 33% (range 26% to 40%), approximating the normal anatomic ratio. Of the 17 patients, 5 (29.4%) had preoperative varus or valgus alignment of the talas >5°. All 5 cases were successfully corrected to within 2° of normal anatomic alignment. This technique allows the surgeon to achieve good visualization of the joint for preparation and to obtain the optimal position of the foot at arthrodesis without compromising the lateral column significance of the fibula. All patients obtained fusion, and minimal complications were associated with the use of this technique.     

Uncemented total ankle arthroplasty in post-traumatic osteoarthritis: 3- to 7-year follow-up

Ankle replacement in post-traumatic arthritis is a challenging procedure, and adequate data are lacking about its results, as most studies are mainly focused on the results of ankle arthroplasty in primary osteoarthritis and rheumatoid arthritis. We present the results of 7 ankle replacements in posttraumatic arthritis with an uncemented total ankle arthroplasty at an average follow-up of 5.1 years (range, 3–7). One ankle had been revised and one ankle showed an unsatisfactory result (with radiographic signs of loosening of the talar component). The average functional score of the 6 surviving prostheses was 68.3 according to Kofoed and 70.8 according to AOFAS. Range of motion averaged 24.1° at follow-up. No infections nor collapse of the talus occurred. No ankles showed areas of periprosthetic osteolysis. Periarticular calcifications were a common finding (3 patients) but not evidently connected to the clinical result. Radiographic signs of progressive degeneration of the neighboring joints were present in three patients at the talonavicular joint and in one patient at the talocalcaneal joint. Ankle arthroplasty with new generation prostheses is a promising procedure but results are still worse than those of replacement of the other major joints of the lower limb. Replacement of the post-traumatic ankle presents particular difficulties and studies should evaluate the results separately from ankles affected by primary osteoarthritis and rheumatoid arthritis.     

Short-term and mid-term outcome of total ankle replacement in haemophilic patients

BackgroundAnkle arthropathy is very frequent in haemophilic patients. Prostheses are valuable alternatives to arthrodesis in non-haemophilic patients. We report the experience of a single centre in France on the use of prostheses in haemophilic patients.MethodsRetrospective study of 21 patients with haemarthropathy who underwent ankle arthroplasty (32 ankles), with additional surgery, if needed, from July 2002 to September 2009 (mean follow-up 4.4 ± 1.7 years). The American Orthopaedic Foot and Ankle Society (AOFAS) ankle–hindfoot scale was used to evaluate pain, function, ankle mobility and alignment.ResultsThe overall AOFAS score improved from 40.2 ± 19.4 (pre-surgery) to 85.3 ± 11.4 (post-surgery). The function score increased from 23.6 ± 7.7 to 35.9 ± 6.7 and dorsiflexion from 0.3° ± 5.0° to 10.3° ± 4.4°. Two patients underwent further ankle arthrodesis. On X-ray, both tibial and talar components were stable and correctly placed in all ankles. Alignment was good.ConclusionAnkle arthroplasty is a promising alternative to arthrodesis in haemophilic patients.
