Tibiotalocalcaneal arthrodesis for end-stage ankle and hindfoot arthropathy:Short-and mid-term clinical outcomes / 北京大学学报(医学版)

Objective:To analyze the clinical data of patients with end-stage ankle and hindfoot ar-thropathy who underwent tibiotalocalcaneal(TTC)arthrodesis by the same surgeon,explore the short-and mid-term clinical results,complications and functional improvement,and discuss the clinical progno-sis and precautions of TTC arthrodesis.Methods:Retrospective analysis was made on the clinical data of 40 patients who underwent TTC arthrodesis by the same surgeon from March 2011 to December 2020.In this study,23 males and 17 females were included,with an average age of(49.1±16.0)years.All the patients underwent unilateral surgery.The clinical characteristics,imaging manifestations,main diagno-sis and specific surgical techniques of the patients were recorded.The clinical outcomes were evaluated by comparison of the American Orthopaedic Foot and Ankle Society(AOFAS)ankle-hindfoot score and visual analogue scale(VAS)between pre-operation and at the last follow-up.The fusion healing time,symptom improvement(significant improvement,certain improvement,no improvement or deterioration)and postoperative complications were also recorded.Results:The median follow-up time was 38.0(26.3,58.8)months.The preoperative VAS score was 6.0(4.0,7.0),and the AOFAS score was 33.0(25.3,47.3).At the last follow-up,the median VAS score was 0(0,3.0),and the AOFAS score was 80.0(59.0,84.0).All the significantly improved compared with their preoperative corre-sponding values(P＜0.05).There was no wound necrosis or infection in the patients.One patient suf-fered from subtalar joint nonunion,which was syphilitic Charcot arthropathy.The median bony healing time of other patients was 15.0(12.0,20.0)weeks.Among the included patients,there were 25 cases with significant improvement in symptom compared with that preoperative,8 cases with certain improve-ment,4 cases with no improvement,and 3 cases with worse symptoms than that before operation.Con-clusion:TTC arthrodesis is a reliable method for the treatment of the end-stage ankle and hindfoot ar-thropathy.The function of most patients was improved postoperatively,with little impact on daily life.The causes of poor prognosis included toe stiffness,stress concentration in adjacent knee joints,nonunion and pain of unknown causes.

Fibula-preserving anterolateral approach for tibiotalocalcaneal arthrodesis: clinical and radiographic outcomes / 中华创伤骨科杂志

Objective:To evaluate the clinical and radiographic outcomes of tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach.Methods:From March 2018 to February 2021, 23 patients underwent tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach at the Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital.Of them, 15 were males and 8 females. Their average age at surgery was 54.4 years (range, from 28 to 72 years). There were 11 cases of traumatic arthritis, 2 cases of Charcot arthropathy, 6 cases of neurogenic equinovarus, 2 cases of traumatic equinovarus, and 2 cases of Kashin-Beck disease. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), visual analogue scale (VAS), foot function index (FFI), hindfoot alignment angle (HA), hindfoot alignment distance (HD), and hindfoot alignment ratio (HR). The tibia-foot angle on lateral weight-bearing and patient satisfaction at the last follow-up and postoperative complications were documented.Results:This cohort were followed up for an average of 24.7 months (from 12 to 48 months). The AOFAS ankle-hindfoot score (78.2 ± 9.2), VAS [2.0 (0.5, 2.0)], FFI [19.0 (10.5, 35.0)], HA (2.7° ± 5.8°), HD [(0.1 ± 0.8) cm] and HR [44.2 (36.4, 59.2)%] at the last follow-up were significantly improved than the preoperative values [43.4 ± 12.7, 4.0 (4.0, 6.0), 98.0 (60.0, 127.0), 22.0° ± 14.3°, (2.2 ± 1.6) cm and 86.0 (66.3, 100.0)%] (all P<0.05). The tibia-foot angle on lateral weight-bearing was 89.0° (87.1°, 90.4°) at the last follow-up. By the Likert scale, 17 cases were very satisfied with the surgery, 4 cases satisfied and 2 cases tolerate, giving a satisfaction rate of 91.3%(21/23). Infection occurred in one case and nonunion in one. Conclusion:Tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach yields good mid- to short-term clinical and radiographic outcomes, showing a strong capability to correct ankle and hindfoot varus and equinus.

Value of Tibiotalocalcaneal Arthrodesis Using Retrograde Intramedullary Nailing in Severe Hindfoot Deformity and Arthritis / 대한정형외과학회잡지

PURPOSE: This study examined the radiological and clinical outcomes of tibiotalocacalcaneal arthrodesis using retrograde intramedullary nailing in a severe hindfoot deformity and ankle/subtalar arthritis. MATERIALS AND METHODS: A total of 22 patients (22 cases) with a severe hindfoot deformity and arthritis underwent tibiotalocalcaneal arthrodesis with retrograde intramedullary nails. The average age was 57.4 years (22–82 years) and the mean follow-up was 29.6 months (12–74 months). The radiological outcomes included an assessment of the preoperative and postoperative coronal ankle alignment, hindfoot alignment, sagittal alignment, and postoperative union time. The clinical outcomes were evaluated using the visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, and postoperative complications. The results were analyzed statistically by dividing the patients into two groups based on a 10° angle of deformity. RESULTS: Regarding the preoperative coronal ankle alignment, 14 patients had a mean varus deformity of 17.8°±14.5° and six had a mean valgus deformity of 8.1°±6.6°. Postoperatively, a satisfactory postoperative coronal ankle alignment of less than 5° was obtained in all patients. Regarding the preoperative hindfoot alignment, 12 patients showed a mean varus deformity of 15.2°±10.5° and six had a mean valgus deformity of 8.1°±4.2°. In total, 94.4% (17 patients) had satisfactory postoperative hindfoot alignment of less than 5°. Radiological union was achieved in 90.9% at an average of 19.2 weeks (12–32 weeks) and there were 2 cases of nonunion. The clinical outcomes showed improvement in the mean VAS and AOFAS scores (p<0.001, p<0.001, respectively). Even a preoperative severe deformity more than 10° showed a significant deformity correction of coronal ankle alignment and hindfoot alignment, postoperatively (p<0.001, p<0.001, respectively). No significant differences were found between the patients with a preoperative coronal ankle deformity more than 10° and those less than 10° regarding the mean postoperative coronal ankle alignment (p=0.162). CONCLUSION: Tibiotalocalcaneal arthrodesis using retrograde intramedullary nailing is an acceptable technique for achieving satisfactory deformity correction, high union rate with minimal complications, and improvement of the clinical outcomes. In addition, tibiotalocalcaneal arthrodesis using retrograde intramedullary nailing is considered an effective treatment option, particularly in severe ankle and hindfoot deformities.

Effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions / 中国修复重建外科杂志

Objective: To investigate the effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions. Methods: Between January 2012 and December 2016, 36 patients (36 feet) with ankle diseases underwent tibio-talo-calcaneal arthrodesis with parallel double thread headless compression screws via minimal anterior and lateral oblique incisions. There were 14 males and 22 females with an average age of 53.8 years (range, 18-76 years). There were 19 cases of left feet and 17 cases of right feet. There were 21 cases of talar necrosis, 7 cases of post-traumatic arthritis, 3 cases of rheumatoid arthritis, 2 cases of tuberculosis infection (inactive), 1 case of talar absence, 1 case of Charcot’s disease, and 1 case of pigmented villonodular synovitis of ankle and subtalar joints. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were 53.7±2.5 and 5.9±0.2, respectively. The operation time was recorded and the wound healing and complications were observed. The bone healing was assessed by X-ray film and CT scanning. The function and pain of joint were evaluated by AOFAS and VAS scores. Results: The mean operation time was 49.8 minutes (range, 33-82 minutes). Incision infection occurred in 1 patient (2.8%) at 3 weeks after operation, and recovered after debridement. The other incisions healed by first intention without complications. Thirty-five patients were followed up with an average of 18.5 months (range, 12-29 months). Imaging examination showed fusion of the ankle and subtalar joints with an average fusion time of 10.9 weeks (range, 8-15 weeks). After 1 year, the AOFAS score (84.7±0.6) and VAS score (0.3±0.1) were significantly higher than preoperative scores ( t=12.596, P=0.000; t=30.393, P=0.000). Conclusion: It is an effective surgical method of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions for end-stage ankle disease because of the less complications incidence and the higher postoperative fusion rate.

The Surgical Outcome of Tibiotalocalcaneal Arthrodesis Using a Retrograde Intramedullary Nail / 대한족부족관절학회지

PURPOSE: Tibiotalocalcaneal arthrodesis has been used as a treatment option for severe deformity including Charcot arthropathy, avascular necrosis of the talus, and severe osteoarthritis of the ankle and subtalar joint. The purpose of this study was to evaluate the result of the surgical outcome of tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail. MATERIALS AND METHODS: Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail was performed by one surgeon in 36 cases. Clinical and radiological finding was evaluated using assessment of fusion time, 5th metatarsal-tibial angle, possibility of postoperative complication, visual analogue scale for pain and American Orthopaedic Foot and Ankle Society (AOFAS) score. RESULTS: Union was achieved in 33 cases at an average of 23 weeks (11~29 weeks). There were 3 cases of nonunion and 1 case of reoperation. Nail-tibial angle tended to be larger in nonunion cases. AOFAS score showed significantly poor outcome at malalignment (> or =5degrees), negative value of 5th metatarsal-tibial angle. CONCLUSION: Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail is considered a useful treatment option for severe destruction and deformity involving ankle and subtalar joint.

PURPOSE: To report the clinical results of tibio-talo-calcaneal arthrodesis fixed with multiple cannulated screws for the cases of painful ankle and hindfoot arthropathy regardless of any deformity or instability. MATERIALS AND METHODS: A retrospective analysis was performed upon 10 patients that underwent tibio-talo-calcaneal arthrodesis from October 1999 to May 2006. There were 4 males and 6 females, with an average age of 63 years (43-70). The etioloty of arthrodesis included 5 osteoarthritis, 2 Charcot joints, 1 rheumatoid arthritis, 1 Tbc arthritis and 1 residual poliomyelitis. Chief complaints were pain in 9 cases and instability in 1 case. Three patients had combined severe varus deformity. Tibio-talo-calcaneal arthrodesis using multiple cannulated screws was performed by transfibular approach for all cases and short leg cast was applied for 12 weeks postoperatively. RESULTS: The average follow-up period was 16.5 months (12-26 months). VAS pain score was average 8.2 (7-10) and modified AOFAS score was average 25 (8-40, total 86) preoperatively. At final follow-up, VAS score was average 1.0 (0-3) and AOFAS score improved to average 66 (58-75). There were 4 complications: 2 nonunion, 1 tibia stress fracture and 1 malunion. Seven of 8 patients were satisfied with the results at final follow-up. CONCLUSION: Fixation with multiple cannulated screws for tibio-talo-calcaneal arthrodesis through transfibular approach is a recommendable surgical option.
