OBJECTIVE: To observe clinical effect of percutaneous minimally invasive osteotomy with 8-shaped bandage and hallux valgus splint fixation in treating moderate hallux valgus. METHODS: Totally 23 patients with moderate hallux valgus were treated with percutaneous minimally invasive osteotomy with 8-shaped bandage and hallux valgus splint fixation from August 2019 to January 2021, and 1 patient was loss to follow-up, and finally 22 patients(30 feet) were included, 4 males (6 feet) and 18 females(24 feet), aged from 27 to 66 years old with an average of(50.59±11.95) years old. Hallux valgus angle (HVA), intermetatarsal angle (IMA), metatarsal span (the distance between the first and the fifth metatarsal bones), changed of soft tissue width, American Orthopaedic Foot and Ankle Society(AOFAS) score, and Visual Analogue Scale (VAS) were collected and compared before operation and 6 months after operation. RESULTS: Twenty-two patients were followed up from 5.7 to 6.4 months with an average of (6.13±0.85) months. The first metatarsal osteotomy of patients were obtained bone union, and deformity of the toes was corrected. Complications such as avascular necrosis of metatarsal head and transfer metatarsalgia were not occurred. Postoperative HVA, IMA, metatarsal span, soft tissue width, VAS, AOFAS score at 6 months were significantly improved compared with pre-operation (P<0.01). According to AOFAS score at 6 months after operation, 10 feet were excellent, 18 good and 2 poor. Two feet with poor were excellent after prolonged 8-shaped bandage and hallux valgus splint fixation time. CONCLUSION Percutaneous minimally invasive osteotomy with 8-shaped bandage and hallux valgus splint fixation for the treatment of moderate hallux valgus could better correct deformity of hallux valgus, relieve foot symptoms, good recovery of postoperative function, and has a significant clinical efficacy.

OBJECTIVE: To compare minimally invasive and traditional Chevron osteotomy in treating patients with mild to moderate hallux valgus. METHODS: Clinical data of 36 patients (36 feet) with mild to moderate hallux valgus from January 2019 to February 2021 were retrospectively analyzed, and divided into minimally invasive osteotomy(minimally invasive group) and traditional Chevron osteotomy(traditional group). There were 16 patients in minimally invasive group, including 1 male and 15 females, aged from 36 to 60 years old with an average of(49.0±9.5) years old;9 were mild and 7 were moderate according to Mann classification;treated with minimally invasive osteotomy with hollow screw fixation. There were 20 patients(20 feet) in traditional group, including 2 males and 18 females, aged from 38 to 65 years old with an average of(50.0±9.2) years old;11 were mild and 9 were moderate according to Mann classification;treated with traditional Chevron osteotomy. Hallux valgus angle (HVA), intermetatarsal angle (IMA) before and after operation at 12 months bewteen two groups were observed and compared, and American Orthopedic Foot and Ankle Society (AOFAS) forefoot score and visual analogue scale (VAS) before and after operation at 6 weeks and 12 months between two groups were compared. RESULTS: Thirty-six patiens were followed up from 14 to 30 months with an average of (21.00±5.77) months. All incisions were healed well at stageⅠwithout infection. There were no significant differences in HVA, IMA, AOFAS forefoot scores and VAS before and after operation at 12 months between two groups(P>0.05). However, AOFAS forefoot scores and VAS of minimally invasive group was significantly better than that of traditionl group at 6 weeks after operation (P<0.05). Postoperative HVA, IMA, AOFAS forefoot scores and VAS at 12 months bewteen two groups were improved better than that of preoperation(P<0.05). CONCLUSION Compared with traditional Chevron osteotomy, minimally invasive osteotomy has less trauma and quicker recovery. Both of them has similar clinical effects, and could receive satisfactory clinical effects, while treatment of minimally invasive osteotomy should pain attention to learning curve.

OBJECTIVE: To explore early efficacy of minimally invasive Chevron Akin(MICA) osteotomy for the treatment of mild to moderate hallux valgus. METHODS: From June 2019 to April 2021, a total of 26 patients (29 feet) with mild to moderate hallux valgus, including 1 male and 25 females aged from 19 to 78 years old with an average of(38.3±19.5) years old, were treated with MICA. Preoperative and postoperative hallux valgus angle(HVA), intermetatarsal angle(IMA) and shortening of the first metatarsal were observed and compared. American Orthopedic Foot and Ankle Society (AOFAS) forefoot scoring system and visual analogue scale (VAS) were applied to evaluate clinical outcome at the final follow-up, and complications were also recorded. RESULTS: All patients obtained followed up from 12 to 33 months with an average of(19.6±5.1) months. HVA and IMA was improved from (32.3±6.6)° and (11.7±3.2)° pre-operatively to (13.0±5.3)° and (6.1±3.2)° post-operatively, respectively, which had a significant difference (P<0.01). The average shortening of the first metatarsal was (2.7±1.1) mm. AOFAS and VAS was improved from (55.7±7.4) and (6.5±1.5) preoperatively and to (88.5±7.9) and (0.7±0.4) respectively at the final follow-up, which also had a significant difference(P<0.01). According to AOFAS score, 15 feet achieved an excellent result, 11 good and 3 moderate. CONCLUSION MICA osteotomy is a safe and reliable surgical technique for mild to moderate hallux valgus with advantages of minimally invasive, rapid recovery, low complication rate and an effect improvement of hallux valgus deformity.

OBJECTIVE: To explore short-term results of minimally invasive Chevron osteotomy with lateral soft tissue release in treating mild to moderate hallux valgus. METHODS: Sixty patients (80 feet) with mild to moderate hallux valgus treated with minimally invasive Chevron osteotomy with lateral soft tissue release from January 2019 to December 2021 were retrospectively analyzed. Among them, there were 5 males (6 feet) and 62 females (74 feet), aged from 20 to 60 years old with an average of (47.2±9.7) years old;54 patients (64 feet) with mild hallux valgus, and 13 patients(16 feet) with moderate hallux valgus. Hallux valugs angle(HVA), Ⅰ-Ⅱ intermetatarsal anlge(Ⅰ-Ⅱ IMA), distal metatarsal articular angle(DMAA)and sesamoid Hardy score were compared before and after operation, and American Orthopaedic Foot and Ankle Society's Hallux Metatarsophalangeal- Interphalangeal (AOFAS Hallux MTP-IP) scale was used to evaluate clinical effects. RESULTS: Sixty-seven patients (80 feet) were followed-up from 6 to 23 months with an average of (13.7±6.5) months. Preopertive HVA, Ⅰ-Ⅱ IMA, DMAA, sesamoid Hardy score and AOFAS Hallux MTP-IP were (27.5±7.0)°, (17.4±4.1)°, (11.4±3.8)°, (4.9±2.6) and (58.2±9.1), respectively;while at the final follow up were(8.3±4.8)°, (6.9±3.0)°, (3.9±2.4)°, (2.7±1.1) and(91.3±2.2);and there were statistical differences between pre-operation and the latest follow-up(P<0.05). There were differences in preopertaive imaging indexes and AOFAS Hallux MTP-IP between 64 mild and 16 moderate hallux valgus feet(P<0.05);while no difference in above indexes at the final follow-up(P>0.05);from the view of degree of improvement, HVA, Ⅰ-Ⅱ IMA, sesamoid Hardy score and AOFAS Hallux MTP-IP in moderate hallux valgus were better than that of in mild hallux valgus(P<0.05). Four patients occurred redness and swelling around incision on the osteotomy site, and cured by local dressing change and oral antibiotics. CONCLUSION Minimally invasive Chevron osteotomy combined with lateral soft tissue release has advantages of correction and functional improvement for mild to moderate hallux valgus.

OBJECTIVE: To evaluate clnical effect of minimally invasive osteotomy with absorbable screws in treating hallux valgus deformity. METHODS: Clnical data of 31 patients with hallux valgus deformity were retrospective analyzed from January 2019 to December 2020, and divided into absorbable screws group (17 patients) and titanium cannulated screw group (14 patients). In absorbable screws group, there were 1 male and 16 females aged from 32 to 72 years old with an average of (54.53±12.12) years old;6 patients on the left side, 5 on bilateral and 6 on the right side;1 patient was mild, 11 moderate and 5 severe;treated with minimally invasive osteotomy and fixation of absorbable screws. In titanium cannulated screw group, there were 2 males and 12 females aged from 18 to 71 years old with an average of (47.57±15.68) years old;4 patients on the left side, 4 on bilateral and 6 on the right side;1 patient was mild, 9 moderate and 4severe;treated with minimally invasive osteotomy and fixation of titanium cannulated screw. Complications between two groups were observed, changes of hallux valgus angle (HVA)and intermetatarsal angle (IMA)were detected and compared before and after operation at 12 months, American Orthopedic Foot and Ankle Society(AOFAS) and visual analogue scale(VAS) before and after operation at 12 months were also compared. RESULTS: All 31 patients were followed up from 13 to 20 months with an average of (16.61±2.47) months. Patients in absorbable screws group were followed up from 14 to 20 months with an average of (16.88±2.80) months, while patients in titanium cannulated screw group were followed up from 13 to 19 months with an average of (16.29±2.05) months;there was no difference between two groups(P>0.05). One patient in absorbable screws group occurred numbness around incision, 3 patients in titanium cannulated screw group occurred complications, including numbness around incision in 1 patient, skin irritation due to internal fixation in 1 patient, and recurrence in 1 case;there was no statistic difference between two groups (χ²=1.651, P=0.199). There were no statistic difference in HVA and IMA between two groups before and after operation at 12 months(P>0.05). There were no statistic difference between two groups in AOFAS and VAS before and after operation at 12 months(P>0.05). CONCLUSION Compare with mainstream fixation with titanium hollow screw after minmally invasive osteotomy, fixation with absorbable screw could achieve comparable clinical outcome on the basis of images and function evaluation.

Recurrence of hallux valgus is one of the most common and difficult complications after surgery. Due to the lack of understanding of 3D deformity of hallux valgus and risk factors for recurrence, the overall recurrence rate is still high, and the choice of treatment is still controversial. Improper operation and severe deformity are known risk factors for recurrence, while the role of unstable of the first plantar train and combined flat foot deformity in the recurrence has been paid more attention by scholars at home and abroad. In addition to the first metatarsophalangeal fusion, modified Lapidus osteotomy and proximal metatarsal osteotomy have been proven to be reliable revision procedures. The purpose of this study is to summarize risk factors for recurrence of hallux valgus after surgery, and to explore the choice of revision surgery after recurrence, in order to provide guidance for prevention and management of recurrence of hallux valgus.

OBJECTIVE: To investigate the method and clinical effect of modified Chevron osteotomy of the distal end of the first metatarsal in the treatment of moderate and severe hallux valgus. METHODS: From January 2015 to January 2019, 28 patients(30 feet) with moderate and severe hallux valgus were treated with modified Chevron osteotomy combined with lateral soft tissue release of the first metatarsophalangeal joint, including 2 males (2 feet) and 26 females (28 feet). The age ranged from 35 to 74 (57.3±9.3) years;10 feet on the left, 16 feet on the right, 2 cases on both sides(4 feet);the course of disease was 3 to 12 (9.32±3.89) years. The changes of hallux valgus angle(HVA), intermetatarsal angle(IMA) between the first and second metatarsals and distal metatarsal articular angle(DMAA) of the first metatarsal were measured and compared before and 6 months after operation. The American Orthopaedic Foot and Ankle Society(AOFAS) thumb joint scoring system was used to evaluate the curative effect. RESULTS: All 28 patients were followed up for 8 to 16 (11.28±3.42) months. The incision healed well in all patients, and there were no complications such as incision infection and metatarsal head necrosis. The healing time of osteotomy site was 6 to 10(7.12±1.34) weeks. Preoperative HVA, IMA, DMAA and AOFAS were (36.06±6.02) °, (21.78±4.16) °, (8.21±2.65) ° and (52.90±10.97) respectively, at six months after operation, they were (8.87±2.46) °, (11.66±2.84) °, (3.65±1.00) ° and (87.45±10.55) respectively, there was significant difference between preoperative and 6 months after operation(P<0.05). At 6 months after operation, AOFAS score was excellent in 20 feet, good in 7 feet and poor in 3 feet. Among the 3 patients with poor scores, 2 were excellent after revision, and 1 was significantly improved after using custom insoles. CONCLUSION Modified Chevron can effectively correct HVA, IMA and DMAA and improve functional recovery. The modified Chevron osteotomy increases the moving distance and the contact of the osteotomy surface. It can be fixed with multiple screws, has strong correction ability, and can exercise early. It is one of the optional methods for the treatment of moderate and severe hallux valgus.
