Operative Treatment of Hallux Valgus Deformity in Male Patients / 대한족부족관절학회지

PURPOSE: We evaluated the result of operative treatment of the hallux valgus in male patients. MATERAILS AND METHODS: Total 11 cases (10 patients) of the hallux valgus deformity that treated with operation were evaluated. Following Mann's radiological classification system, there was 1 cases of mild, 8 cases of moderate, and 2 cases of severe. Preoperative, postoperative, postoperative 3 months and postoperative 6 months follow up standing radiographs were used as radiologic evaluation. And we evaluated radiological outcomes by hallux valgus angle (HVA), first-second intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), proximal phalangeal articular angle (PPAA) and clinical outcomes by hallux-metatarsophalangeal scale of American Orthopaedic Foot and Ankle Society (AOFAS) score. RESULT: Radiologically, the mean preoperative HVA 37degrees and IMA 13.7degrees were improved postoperatively as HVA 11.9degrees and IMA 4.7degrees, and the mean preoperative DMMA 29.4degrees and PPAA 8.6degrees were improved postoperatively DMMA 13.9degrees and PPAA 7degrees. But, postoperative 6 months follow up HVA, IMA, DMMA and PPAA was increased at 14.2degrees, 6.3degrees, 16.1degrees and 8.3degrees. Average AOFAS score were improved from 61.2 points to 75.2 points. CONCULSION: In our study, operative treatment of hallux valgus in male patients with proximal metatarsal osteotomy and distal soft tissue procedure showed good results but it was necessary to pay attention to increase aspect of follow up radiologic measurements.

Treatment of Moderate Hallux Valgus with Proximal Chevron Metatarsal Osteotomy and Distal Soft Tissue Procedure / 대한족부족관절학회지

PURPOSE: The authors intended to analyze the operative results of moderate hallux valgus with proximal chevron metatarsal osteotomy and distal soft tissue procedure. MATERIALS AND METHODS: Seventy feet of fifty-seven patients were followed for more than 1 year after the proximal chevron metatarsal osteotomy. The mean age was 47.2 years, and the mean follow up period was 2 years and 3 months. Clinically preoperative and postoperative AOFAS MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, hallux valgus interphalangeal angle, the intermetatarsal angle and sesamoid position before and after the operation were analyzed. RESULTS: Additional Akin osteotomy was performed 48 out of 70 feet. Clinically AOFAS MP-IP scale was increased from 60.4 points preoperatively to 89.8 points postoperatively. Ninety-four percents of the patients were satisfied with the results. Radiologically hallux valgus angle was decreased from 34.8 degrees preoperatively to 12.8 degrees postoperatively. The intermetatarsal angle was decreased from 15.7 degrees preoperatively to 8.0 degrees postoperatively. Hallux valgus interphalangeal angle was increased from 7.4 degrees preoperatively to 9.8 degrees postoperatively. There were 3 recurrences, 1 hallux varus and 3 minor wound infections. There were no nonunion or malunion of the 1st metatarsal. CONCLUSION: Proximal chevron metatarsal osteotomy with distal soft tissue procedure and additional Akin osteotomy appears to be safe and satisfactory procedure.

Correction of Sesamoid after Proximal Metatarsal Osteotomy and Distal Soft Tissue Procedure in Hallux Valgus / 대한족부족관절학회지

PURPOSE: A retrospective review of the radiographs of the proximal metatarsal osteotomy and distal soft tissue procedure for hallux valgus, evaluating the correction of the tibial sesamoid, was undertaken. We evaluated the correlation between the reduction of the tibial sesamoid and the clinical outcomes. MATERIALS AND METHODS: 17 patients (23 cases) with moderate to severe hallux valgus deformity underwent the proximal metatarsal osteotomy and distal soft tissue procedure. The preoperative and last follow-up radiographs were reviewed according to the tibial sesamoid grade classification recommended by the Research Committee of the American Orthopedic Foot and Ankle Society (AOFAS). We divided them into two groups according to the reduction of the tibial sesamoid. We anaylyzed the clinical outcomes in each group according to Mayo Clinic Forefoot Scoring System (FFSS). RESULTS: In all of the patients, the preoperative tibial sesamoid position were grade 2 or greater. At the last follow-up, 52% (n=12) were grade 1 or less (Group I) and 48% (n=11) were grade 2 or greater (Group II). In group I, the forefoot score was improved from preoperative mean value of 32.0 points to final follow-up value of 66.3 points. In group II, the forefoot score was improved from preoperative mean value of 31.7 points to final follow-up value of 65.9 points. There was no statistical significance between postoperative, average scores in group I and II (p>0.05). CONCLUSION: The position of the tibial sesamoid was corrected insufficiently in almost half of all cases. In view of clinical outcomes, there was no significant difference between the corrected group and the other group.

A Comparison of Operative Treatment of Hallux Valgus with a Proximal Metatarsal Osteotomy and with a Modified Chevron Osteotomy / 대한족부족관절학회지

PURPOSE: We compared the result of a proximal metatarsal closed wedge osteotomy and soft tissue procedure with a modified chevron osteotomy and soft tissue procedure in the treatment of hallux valgus. MATERIALS AND METHODS: Between March 1999 and February 2003, we performed proximal metatarsal closed wedge osteotomy and soft tissue procedure on 17 feet (12 patients), and modified chevron osteotomy and soft tissue procedure on 12 feet (9 patients). RESULTS: According to Mayo clinic forefoot scoring system (FFSS), group 1, with proximal metatarsal closed wedge osteotomy, shows 67.2 points postoperatively and group 2, with modified chevron osteotomy, shows 68.5 points postoperatively. In group 1, the average correction of hallux valgus angle and intermetatarsal angle was 20.8 degrees and 4.8 degrees, respectively. In group 2, the average correction of hallux valgus angle and intermetatarsal angle was 19.9 degrees and 4.7 degrees, respectively. The average shortening was 3.15 mm in group 1 and 1.38 mm in group 2. CONCLUSION: We obtained relatively good clinical and radiographic result in this study. The effect on shortening of the first metatarsal was greater in the proximal metatarsal closed wedge osteotomy than modified chevron osteotomy, but the metatarsal shortening did not related with metatarsalgia. So, both techniques seems optimal surgical treatment for hallux valgus deformity.

Correlation of Correction Angle with Pain at First Metatarsophalangeal Joint in the Treatment of Hallux Valgus / 대한정형외과학회잡지

PURPOSE: We evaluated the correlation between correction angle and pain of the first metatarsophalangeal joint in the treatment of hallux valgus. MATERIALS AND METHODS: The 28 cases (20 patients) with moderate to severe hallux valgus deformity and pain of the first metatarsophalangeal joint who underwent the distal soft tissue procedure and proximal metatarsal closing wedge osteotomy, were divided into two groups, Group I: no pain of the first metatarsophalangeal joint after surgery, and Group II: with persisting pain. We analyzed the correc-tion angle and pain of the first metatarsophalangeal joint in each group, preoperatively and at the last follow-up. All of the patients were women and their mean age was 58 years old. The average follow-up time was 18 months. RESULTS: At the last follow-up, the 21 feet (75%) were free of pain of the first metatarsophalangeal joint. In 7 feet (25%) pain persisted. In group I, sufficient deformity correction was obtained, but in group II, the deformity was corrected insufficiently. A high correlation was observed between correction angle and pain relief. CONCLUSION: A high correlation was obtained between correction angle and pain of the first metatarsophalangeal joint in the treatment of hallux valgus deformity. Therefore, in view of the patient's expectation of pain relief, meticulous attention should be paid to the correction of hallux valgus deformity.

Treatment of Hallux Valgus with a Proximal Metatarsal Osteotomy and Distal Soft: Tissue Procedure / 대한정형외과학회잡지

The deformity of hallux valgus is associated with three hasic prohlems: a prominent rnedial eminence, contracted soft-tissue structures on the lateral side of the great toe, and an altered intermetatarsal angle between the first and second metatarsal. We retrospectively have reviewed the results for thirty-one patients(47 feet) in whom a hallux vaigus deformity had heen conected with the release of the distal soft tissues, excision of the medial eminence, plication of the medial part of the capsule, and proximal crescentic osteotomy of the first metatarsal. The patients were followed for an average of twenty months(range, twelve to twenty-eight months). There were nine cases with mild defoimity, twenty-nine cases with moderate deformity, nine cases with severe deformity. The preoperative hallux valgus angle averaged 38.1 degrees, and the immediate postoperative angle averaged 6.7 degrees. The preoperative intermetatarsal angle averaged 17.1 degrees, and the immediate postoperative angle, 7.6 degrees. At the latest follow-up, the hallux valgus angle averaged 19.3 degrees, the intermetatarsal angle averaged 9.9 degrees. We found that the more the deformity, the lesser the congruency. 74.5% of the patients were satisfied with the result of the procedure. They stated that, eiven the same circumstances, they would have the operation again. The most common complication was recurrence of the nallux valgus, which occurred in nine feet(five patients). The other complications included pain under a fibular sesamoid in one foot, severe hypoesthesia on the medial aspect ot the big toe in one foot, and superficial wound infection in one foot.
