OBJECTIVE@#To evaluate the early effectiveness of a new minimally invasive plate in the treatment of varus-type ankle arthritis.@*METHODS@#A clinical data of 15 patients with varus-type ankle arthritis who met the selection criteria between March 2021 and October 2021 were retrospectively analyzed. All the patients were treated with medial open-wedge supramalleolar osteotomy and fibular osteotomy. The osteotomies were fixed with the new minimally invasive plate. There were 7 males and 8 females with an average age of 49.8 years (range, 16-71 years). The causes of ankle arthritis included post-fracture deformity in 1 case, sprain in 8 cases, and acquired clubfoot in 1 case; and 5 cases were without obvious factors. The disease duration ranged from 1 to 12 years, with an average of 4.1 years. Comparisons were made between pre-operation and the last follow-up in the Takakura staging, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, foot function index (FFI), visual analogue scale (VAS) score, tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).@*RESULTS@#All incisions healed by first intention. All patients were followed up 7-18 months (mean, 12.8 months). At last follow-up, the AOFAS ankle-hindfoot score, FFI, VAS score, and Takakura staging significantly improved when compared with the preoperative ones ( P<0.05). X-ray films showed that the osteotomy healed at 3 months after operation. At last follow-up, TAS significantly increased and TT decreased when compared with the preoperative ones ( P<0.05), and the difference in TLS between pre- and post-operation was not significant ( P>0.05). Complications included 1 case of intraoperative screw breakage and 2 cases of nerve injury of the affected foot. None of the patients complained of significant discomfort at the plate placement during follow-up, and no loosening of the internal fixator occurred. Eleven patients were very satisfied with the effeectiveness, while 4 were relatively satisfied.@*CONCLUSION@#The new minimally invasive plate for the varus-type ankle arthritis has good early effectiveness in relieving ankle pain, correcting deformity, improving limb alignment and ankle function, and reducing the incidence of postoperative incisional complications.

Objective:To explore the short- and mid-term clinical outcomes of surgical treatment of chronic Lisfranc injuries.Methods:A retrospective analysis was conducted of the clinical and imaging data of the 19 patients with chronic Lisfranc injury who had been treated surgically from April 2013 to September 2020 at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. There were 13 males and 6 females, aged from 25 to 58 years (mean, 49 years). The median course of disease before operation was 24 months (from 3 to 312 months). All patients underwent fusion of the 1st, 2nd and 3rd tarsometatarsal joints (TMTJ) plus reduction and fixation or arthroplasty of the 4th and 5th TMTJ by the same surgeon. The clinical outcomes were evaluated by comparison of the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS) and Lublin score between pre-operation and the final follow-up and by Likert satisfaction scale and post-operative complications as well.Results:The 19 patients were followed up for (66.1±23.2) months (from 12 to 104 months). At the final follow-up, the AOFAS midfoot score was 87 (79, 90), the VAS score 1 (0, 2), and the Lublin score 70 (60, 75), all significantly improved compared with their preoperative corresponding values [51 (44, 63), 4 (4, 6) and 50 (40, 55), respectively] ( P<0.05). Sixteen patients were satisfied with their surgery. Fusion was not healed in 3 cases; plate breakage happened in one case but none of the cases had infection or other complications related to the skin or wound. Conclusion:Fusion of the 1st, 2nd and 3rd TMTJ plus reduction and fixation or arthroplasty of the 4th and 5th TMTJ can lead to good short- and mid-term clinical outcomes in the surgical treatment of chronic Lisfranc injuries.

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.

Objective:To evaluate the radiologic and clinical outcomes of supramalleolar dome osteotomy in the treatment of varus-type ankle arthritis.Methods:From June 2018 to December 2019, 13 patients with varus-type ankle arthritis underwent supramalleolar dome osteotomy at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. Of them, 13 (5 males and 8 females) were included in the study. Their average age at surgery was 47.2 years (range, from 16 to 65 years). By the modified Takakura staging for arthritis, 3 cases were stage 2, 4 cases stage 3a and 6 cases stage 3b. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), foot function index (FFI), visual analogue scale (VAS), Takakura staging, dorsal extension, plantar flexion, range of motion (ROM), tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).Results:This cohort were followed up for 12 to 29 months (average, 17.2 months). At the last follow-up, AOFAS score (86.5±8.0), FFI (14.5±1.6), VAS score (1.5±1.0), Takakura staging (2.7±1.3), ROM (39.4°±8.0°), TAS (92.4°±6.0°), TT (3.7°±4.4°) were significantly improved than the preoperative values (68.3±14.4, 43.7±3.0, 4.2±1.4, 3.2±0.8, 43.3°±7.6°, 78.2°±8.3° and 7.0°±5.1°), and dorsal extension (10.9°±4.4°) was significantly smaller than the preoperative value (13.6°±5.1°) (all P<0.05). There were no significant differences between preoperation and the last follow-up in plantar flexion (29.7°±4.6° versus 28.5°±5.2°) or TLS (77.8°±4.5° versus 78.1°±5.3°) ( P>0.05). Conclusions:Supramalleolar dome osteotomy has shown promising short-term clinical efficacy in the treatment of varus-type ankle arthritis. It can significantly relieve pain, improve function, substantially correct deformity and retard progression of arthritis, but it may affect dorsal extension.

Objective To analyze the associations of age and gender with post-operative outcomes after pilon fracture and the effect of interaction between age and gender on the outcomes.Methods A retrospective cohort study was performed of the 101 successive patients with pilon fracture who had been treated by open reduction and internal fixation from March 2009 to November 2013 and completely followed up.The distributions of potential prognostic factors (diabetes,injury mechanism,open fracture,Rüedi-Allg(o)wer classification and AO classification) were analyzed in different age and gender groups.The outcomes were evaluated in terms of reduction quality by the Burwell-Charnley criteria,time for return to work,traumatic osteoarthritis by Kellgren-Lawrence grading scale and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.The odds ratio and regression coefficients were estimated by Logistic regression and linear regression model;P values for interaction between age and gender were estimated by likelihood ratio tests.Results Of all the 101 pilon patients,84 were male and 12 were the aged.The distributions of gender (P =0.028) and mechanism (P =0.032) were significantly different between the aged and the younger patients,showing there were more females in the aged patients and low-energy injury was more likely to cause a pilon fracture in the aged patients.As multivariate analyses suggested,with the above influencing factors controlled,a median follow-up of 41.2 months revealed age was an independent favorable prognostic factor for reduction quality (OR =3.919,P =0.041).The association between gender and time for return to work was significantly different between the aged and the younger patients,as indicated by interaction analyses (P =0.030).Conclusions There may be more females in the aged patients with pilon fracture than in the younger ones.It is likely that the aged patients sustain a pilon fracture because of low-energy injury and achieve a fracture reduction of poorer quality.Although the quality of reduction may be poorer for the aged,there may be no significant difference between the aged and the younger patients in the mid-long-term AOFAS score.It is advisable for surgeons to provide personalized treatment to better help the patients.
