OBJECTIVE: To explore clinical effect of Scarf osteotomy combined with soft tissue balance in treating severe hallux valgus. METHODS: Totally 38 patients(50 feet) with severe hallux valux who underwent Scarf osteotomy combined with soft tissue balance surgery from June 2019 to June 2021 were retrospectively analyzed, aged from 29 to 64 years old with an average of(54.7±6.8) years old; 26 feet on the left side and 24 feet on the right side;the courses of disease ranged from 5 to 23 years with an average of (12.4±3.9) years. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA) were compared before and after operation, and postoperative complications was observed. American orthopedic foot ankle society(AOFAS) score before operation and final follow-up was used to evaluate recovery of forefoot function, and visual analogue scale (VAS) was used to evaluate pain relief. RESULTS: Thirty-eight patients (50 feet) were followed up from 15 to 23 months with an average of (18.3±3.2) months. Preoperative HVA, IMA and DMAA were (44.61±3.92)°, (18.74±2.51)°, (12.85±2.11)°, and improved to (13.45±2.13)°, (7.83±1.36)°, (7.03±1.39)°at final follow-up, which had statistical differneces(P<0.05). No delayed union or nonunion of osteotomy end, fracture or loosening of internal fixation, hallux varus occurred. VAS and AOFAS score improved from (6.81±2.14), (43.6±8.4)points before operation to (1.97±0.78), (87.6±5.2) points at final follow-up, which had statistical difference(P<0.01). According to AOFAS at final follow-up, 20 feet got excellent result, 28 feet good and 2 feet moderate. CONCLUSION Scarf osteotomy combined with soft tissue balance release for severe hallux valgus has good stability and corrective effect, but learning curve and postoperative complications should be paid attention.

PURPOSE: The aim of this study was to investigate new point-connecting measurements for the hallux valgus angle (HVA) and the first intermetatarsal angle (IMA), which can reflect the degree of subluxation of the first metatarsophalangeal joint (MTPJ). Also, this study attempted to compare the validity of midline measurements and the new point-connecting measurements for the determination of HVA and IMA values. MATERIALS AND METHODS: Sixty feet of hallux valgus patients who underwent surgery between 2007 and 2011 were classified in terms of the severity of HVA, congruency of the first MTPJ, and type of chevron metatarsal osteotomy. On weight-bearing dorsal-plantar radiographs, HVA and IMA values were measured and compared preoperatively and postoperatively using both the conventional and new methods. RESULTS: Compared with midline measurements, point-connecting measurements showed higher inter- and intra-observer reliability for preoperative HVA/IMA and similar or higher inter- and intra-observer reliability for postoperative HVA/IMA. Patients who underwent distal chevron metatarsal osteotomy (DCMO) had higher intraclass correlation coefficient for inter- and intra-observer reliability for pre- and post-operative HVA and IMA measured by the point-connecting method compared with the midline method. All differences in the preoperative HVAs and IMAs determined by both the midline method and point-connecting methods were significant between the deviated group and subluxated groups (p=0.001). CONCLUSION: The point-connecting method for measuring HVA and IMA in the subluxated first MTPJ may better reflect the severity of a HV deformity with higher reliability than the midline method, and is more useful in patients with DCMO than in patients with proximal chevron metatarsal osteotomy.

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.

OBJECTIVETo investigate efficacy of simple osteotomy for correct hallux valgus,and explore its scope and condition.

METHODSFrom December 2009 to April 2011, 20 patients (32 feet) with hallux valgus were treated by simple osteotomy. There were 1 male (1 foot), 19 females (31 feet) with an average age of 40 years (ranged, 22 to 64 years). The course of disease ranged from 2 to 31 years(mean 12 years). Among them, 6 feet were mild, 20 feet were moderate, 6 feet were serious. Patients had symptoms of metatarsophalangeal joint pain, but tensity of lateral soft tissue were normal. Hallux Valgus Angle (HVA) and Intermetatarsal Angle (IMA) were examined before and after treatment. The criteria of hallux valgus was used to evaluate the effects from valgus deformity, activity of metatarsophalangeal joint, satisfaction of patients.

RESULTSTwenty patients were followed up from 6 to 18 months with an average of 8.5 months. The wounds were healed well, no infection and metatarsal head necrosis occurred, 95.1% of patients were satisfied with the efficacy. Average AOFAS score increased from preoperative (53.1 +/- 7.5) points to the final follow-up (93.1 +/- l.9) points (P<0.05), the average correct HVA increased from preoperative (33.4 +/- 7.8) degrees to postoperative (11.9 +/- 3.6) degrees (P<0.05), the average IMA were decreased from preoperative (12.3 +/- 3.0) degrees to postoperative (6.3 +/- 1.9) degrees (P<0.05), tibial sesamoid position improved from 1.9 to 0.9 (P<0.05).

CONCLUSIONthe main pathological changes of hallux valgus patients with normal tension of lateral soft tissue is metatarsal adduction, simple osteotomy can get satisfactory results, no need to cut adductor muscle.

BACKGROUNDTreating developmental dysplasia of the hip is often challenging. The difficulties include not only the hip surgery itself but also the treatment of the associated lower-limb valgus deformity. However, there have been very few studies on such deformity in patients with developmental hip dysplasia. In this study, we investigated the prevalence and severity of lower-limb valgus deformity, along with the relationship between the severity of valgus deformity and mechanical alterations of the hip or the ipsilateral knee.

METHODSTwo hundred and six affected lower limbs of 116 adult patients with untreated developmental dysplasia of the hip were included in the study, grouped according to the severity of hip dysplasia. Each study participant's radiographs were measured to quantitatively evaluate the mechanical axis deviation of the lower limb, and further to evaluate the prevalence and severity of the lower-limb valgus deformity. Some mechanical alterations of the hip and the ipsilateral knee were also measured on the radiographs.

RESULTSOf the affected lower limbs, 14.1% had valgus deformities. Study participants with Crowe type III hip dysplasia had the most severe deformity and the highest prevalence of deformity. Severity of valgus deformity had a strong positive correlation with the lateral migration of the femoral head but not with the superior migration. A decreased lateral distal femoral angle contributed to the lower-limb valgus deformity, and the lateral distal femoral angle had a strong negative correlation with the severity of valgus deformity.

CONCLUSIONSHip dysplasia is commonly associated with lower-limb valgus deformity, and the severity of the lower-limb valgus deformity is mostly affected by lateral migration but not superior migration of the femoral head. The valgus deformity may originate mainly in the distal femur, in addition to the hip joint itself. These findings can be taken into account when planning to treat the patients with hip dysplasia.
