Akin Osteotomy

Background: Minimally invasive distal linear metatarsal osteotomy is commonly performed to correct mild-to-moderate hallux valgus. The technique is easy to perform, fast, and has a low complication rate with satisfactory clinical results. However, it has so far not been applied to hallux valgus with concomitant hallux valgus interphalangeus deformity. Objective: We aimed to investigate the short-term clinical results of distal linear metatarsal osteotomy combined with Akin osteotomy in hallux valgus with concomitant hallux valgus interphalangeus deformity. Methods: We retrospectively reviewed 10 patients (10 feet) who underwent surgery for hallux valgus with hallux valgus interphalangeus between 2012 and 2016. Akin osteotomy was performed and fixated with a screw/K-wire, followed by distal linear metatarsal osteotomy and K-wire fixation. Clinical evaluations pre- and postoperatively used the Japan Society for Surgery of the Foot (JSSF) scale and the Visual Analog Scale (VAS). Radiography pre-and postoperatively assessed the hallux valgus, hallux valgus interphalangeus, and the intermetatarsal angle. Results: The mean follow-up period was 20.2 months. Both the JSSF and VAS score improved significantly, from 64.5 to 90.0 and from 5.5 to 1.1, respectively. In all patients, bone healing was complete within four months with no osteonecrosis of the metatarsal head or malunion at the osteotomy site. The hallux valgus angle improved from 31.5° to 7.7°, the hallux valgus interphalangeus angle from 17.2° to 5.8°, and the intermetatarsal angle from 11.7° to 5.5°. Conclusion: Distal linear metatarsal osteotomy combined with Akin osteotomy safely and effectively corrects mild-to-moderate hallux valgus with hallux valgus interphalangeus deformity.

The Austin osteotomy is a widely accepted method for correction of mild and moderate hallux valgus. In view of publications by Kitaoka et al. in 1991 and by Mann and colleagues, a more radical lateral soft tissue procedure was added to the originally described procedure. From September 1992 to January 1994, 85 patients underwent an Austin osteotomy combined with a lateral soft tissue procedure to correct their hallux valgus deformities. Seventy-nine patients (94 feet) were available for follow-up. The average patient age at the time of the operation was 47.1 years, and the average follow-up was 16.2 months. The average preoperative intermetatarsal angle was 13.9°, and the average hallux valgus angle was 29.7°. After surgery, the feet were corrected to an average intermetatarsal angle of 5.8° and an average hallux valgus angle of 11.9°. Sesamoid position was corrected from 2.1 before surgery to 0.5 after surgery. The results were also graded according to the Hallux Metatarsophalangeal Interphalangeal Score, and the functional and cosmetic outcomes were graded by the patient. Dissection of the plantar transverse ligament and release of the lateral capsule repositioned the tibial sesamoid and restored the biomechanics around the first metatarsophalangeal joint. There was no increased incidence of avascular necrosis of the first metatarsal head compared with the original technique.

Category: Lesser Toes Introduction/Purpose: The valgus deviation of lesser toes is often found in the hallux valgus patients. It has been known that valgus deviation of lesser toes remain unchanged even after correction of hallux valgus. The purpose of this study was to determine whether valgus deviation of lesser toes can be corrected after proximal chevron metatarsal osteotomy (PCMO) and Akin osteotomy for the hallux valgus patients, and to evaluate the factors affecting the degree of correction. Methods: The study is based on 116 feet (89 patients) of moderate to severe hallux valgus that underwent proximal chevron metatarsal osteotomy with Akin ostetomy. Hallux valgus angle (HVA), inter-metatarsal angle (IMA), valgus angle of 2nd, 3 rd, 4th metatarso-phalangeal joint were assessed preoperatively and postoperative 6 month, 1 year and yearly. VAS pain cores, American Orthopedic Foot and Ankle Society metatarsophalangeal-interphalangeal (AOFAS MTP-IP) scale and patient satisfaction were evaluated preoperatively and at subsequent follow-up. Results: The average follow-up was 30.6 months (range,12-99). The mean HVA and IMA reduced from 34.4° to 8.7° and 15.9° to 5.3° respectively at the final follow-up. Patients with more severe HVA showed higher degree of valgus deviation of lesser toes than those with lesser HVA. The valgus angle of 2nd,3 rd,4th MTP joints reduced from 8.9°, 6.7°, 2.4° preoperatively to 5.6°, 4.9°, 1.3° respectively at the final follow-up (p<0.05). The more HVA corrected, the more valgus deviation of lesser toe was found corrected. There was no significant difference in the degree of lesser toe correction angle according to follow up period after postoperative 1 year. The mean VAS and AOFAS scores significantly improved from 6.0, 60.9 to 1.2, 92.0 at the final follow-up, respectively (P<0.05). Conclusion: Unlike the previous reports, the current study showed significant reduction of the valgus angle of 2nd, 3 rd, 4th MTP joints after PCMO and Akin osteotomy for the moderate to severe HV without additional corrective lesser toe surgery.

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Loss of correction in hallux valgus (HV) deformity following distal chevron metatarsal osteotomy (DCO) has been demonstrated in short-term follow-up with HV recurrence rates of up to 75% reported in the long-term. The purpose of this study was to evaluate the radiographic effect of the DCO on the anatomic and mechanical axes of the first metatarsal. Our hypothesis was that patients undergoing DCO would have improvement in the mechanical metatarsal axis but worsening of the anatomic axis. Methods: This was a retrospective single surgeon case series of all patients who underwent DCO for HV between 2017 and 2019. Patients were included if they had both preoperative and postoperative weightbearing foot radiographs. The primary outcomes were the change in anatomic first-second intermetatarsal angle (a1-2IMA, defined by the metatarsal diaphyseal axis) and the change in mechanical first-second intermetatarsal angle (m1-2IMA, defined by the axis from the center of the metatarsal head to the metatarsal base). Secondary outcomes included the change in hallux valgus angle (HVA) and medial sesamoid position (medial sesamoid in relation to the mechanical axis of the metatarsal). Change in second-third intermetatarsal angle (2-3IMA, defined by the metatarsal diaphyseal axis) was measured to control for any inconsistencies in radiographic technique. Given the relatively small patient cohort, the non-parametric Wilcoxon signed rank test and Mann Whitney U test were used for statistical analysis. Results: 41 feet were included for analysis with a mean follow-up of 20.4 weeks. The a1-2IMA increased significantly (mean, 4.0 degrees, p<0.001) while the m1-2IMA decreased significantly (mean, 4.6 degrees, p<0.001) following DCO. There was a significant improvement in HVA (mean, 13.2 degrees, p<0.001). No changes were noted in 2-3IMA (mean, 0.0 degrees, p=0.834). (Table 1) Medial sesamoid position was improved in 22 feet (53.7%). Patients with improved sesamoid position were noted to have a significantly larger decrease in m1-2IMA (mean, 5.3 versus 3.8 degrees, p=0.01) and a smaller increase in a1-2IMA (mean, 3.4 versus 4.7 degrees, p=0.02) compared to patients with no improvement in sesamoid position. Conclusion: Distal chevron osteotomy for HV is associated with an increase in the anatomic intermetatarsal angle despite improvements in the m1-2IMA, HVA and medial sesamoid position. Patients with improved sesamoid position were associated with greater correction of the mechanical first metatarsal axis. Our findings may suggest the presence of intermetatarsal instability, which could limit the power of DCO in HV correction for more severe deformities and provide a mechanism for HV recurrence.

We evaluated the results of 33 feet in 23 patients who underwent a basilar crescentic osteotomy with a modified McBride procedure with a minimum 24-month follow-up. The average hallux valgus improved from 37.5° to 13.8° and the intermetatarsal 1–2 angle from 14.9° to 4.7°. The angle of declination of the first metatarsal was found to have dorsiflexed an average of 6.2°. Unfortunately, osteotomies secured with staples dorsiflexed to a greater degree. Bilateral foot surgery produced results similar to those with unilateral procedures. Four of our patients developed a hallux varus (range 2–8°); however, none were dissatisfied at the time of evaluation. Although this bunion procedure resulted in more prolonged swelling and pain than a distal osteotomy, it should be considered for more complex deformities to avoid the failure that a distal metatarsal osteotomy might produce given a high 1–2 intermetatarsal angle or a high hallux valgus angle.

Some authors reported the results from percutaneous distal metatarsal osteotomy for hallux valgus recently. On the other hand, there are few reports of percutaneous proximal metatarsal osteotomy. The purpose of the present study was to evaluate the radiographic results of percutaneous proximal closing wedge osteotomy with Akin osteotomy for correction of severe hallux valgus and increasing longitudinal arch height. Consecutive 17 feet (mean age = 70.8 years) were investigated. The mean follow-up was 22 months. Excision of medial eminence, distal soft tissue release, and Akin osteotomy were all performed percutaneously and concurrently. Weight-bearing anteroposterior and lateral radiographs of the feet were acquired preoperatively and at final follow-up. On the anteroposterior radiographs, hallux valgus angle, intermetatarsal angle, and first metatarsal shortening were measured. On the lateral radiographs, talometatarsal angle, calcaneal pitch angle, and first metatarsal dorsiflexion were measured. The average improvements in hallux valgus angle and intermetatarsal angle were 27.6° and 9.9°, respectively. The average first metatarsal shortening was 2.7 mm. The first metatarsal dorsiflexion improved by 2.2°; however, other parameters did not improve significantly. In conclusion, percutaneous proximal closing wedge osteotomy with Akin osteotomy corrects severe hallux valgus; however, the procedure does not increase the medial longitudinal arch.

Metatarsus Adductus

Category: Bunion Introduction/Purpose: Hallux valgus treatment in the setting of associated metatarsus adductus is less common and not well described. The presence of metatarsus adductus reduces the gap between the first and second metatarsals. Consequently, it complicates the measurement of the first-second intermetatarsal angle and can limit the area available for transposition of the first metatarsal head. If distal metatarsal articular angle (DMAA) is also increased here, it is difficult to correct. We investigated the effects of rotational distal chevron metatarsal osteotomy (DCMO) on hallux valgus associated with metatarsus adductus and increased DMAA. Methods: Twelve patients, (12 female, 15 feet), of average age 59 (SD 23) with symptomatic hallux valgus associated with metatarsus adductus and increased DMAA underwent a rotation DCMO and were reviewed at an average of 12 months postoperatively. Clinically preoperative and postoperative AOFAS hallux MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, the 1st intermetatarsal angle, DMAA before and after the operation was analyzed. Results: Distal Chevron osteotomy was done in 15 cases. After DCMO, The distal fragment was translated to laterally as far as possible and rotated to reduce DMAA. Clinically AOFAS scale was increased from 65.3 points preoperatively to 92.2 points postoperatively. Two patients were not satisfied with the results. Radiologically hallux valgus angle was decreased from 21.8° preoperatively to 8.5° postoperatively. The first intermetatarsal angle was decreased from 11.8° preoperatively to 6.7° postoperatively. DMAA was decreased from 15.8° preoperatively to 5.5° postoperatively. Conclusion: The rotational DCMO was an effective procedure for correcting hallux valgus associated with metatarsus adductus and increased DMAA. It allowed good realignment of the first MTP joint without the need for lesser metatarsal surgery to reduce the metatarsus adductus.

Twenty-six patients with moderate-to-severe hallux valgus deformities were evaluated before and after treatment. All of the patients had incongruent great toe joints. The patients underwent modified proximal crescentic osteotomy, which was termed proximal oblique crescentic osteotomy. The results were evaluated at an average follow-up time of 55 weeks. Objective criteria were hallux valgus angle, intermetatarsal angle, shortening of the first metatarsal, and angulation at the osteotomy site. Clinical evaluation was made according to the rating system of the American Orthopaedic Foot and Ankle Society. The mean correction of the hallux valgus and intermetatarsal angles was 22.1° and 9.9°, respectively. Short-term results indicate that proximal oblique crescentic osteotomy is effective in the treatment of hallux valgus; its advantages over other procedures include its technical ease and low rate of complications.

Criteria For Evaluation

From 1988 to 1995, 96 patients (161 feet) underwent a modified Mitchell distal metatarsal osteotomy performed for mild-to-moderate hallux valgus. On AP x-rays of the standing foot, the average intermetatarsal angle was corrected from 15° to 9°, and the first metatarsophalangeal angles were corrected from an average of 41° to 15°. Criteria for evaluation of clinical results included relief of pain, appearance of foot, and shoe wear. After an average follow-up of 38 months, the overall satisfaction rate was 92.5%. Complications included 13 pin tract infections, two delayed unions, and two correction losses. The most common late sequela was transfer metatarsalgia of the lesser toes, which occurred in 20 feet (12.4%), leading to some dissatisfaction. The Mitchell osteotomy can be used on cases with less than 20° of intermetatarsal angle, offering a stable construct with easy postoperative care.

Background: We compared the radiographic and clinical outcomes of moderate and severe hallux valgus treated by extended distal chevron osteotomy (EDCO) and distal soft tissue release (DSTR). Methods: We performed a retrospective analysis comparing the utility of EDCO for the treatment of moderate (36 patients, 46 feet) and severe (36 patients, 42 feet) hallux valgus. The radiologic outcomes were evaluated based on the preoperative and 3-year follow-up x-rays. The clinical results were investigated based on the 3-year follow-up Manchester-Oxford Foot Questionnaire (MOXFQ), patient satisfaction, and postoperative complications. Results: The mean postoperative intermetatarsal angle, hallux valgus angle, tibial sesamoid position, and relative metatarsal bone length were significantly different compared with the preoperative values for both the moderate and severe groups ( P < .001). At 3-year follow-up, intergroup differences were observed in the mean postoperative intermetatarsal angle ( P = .001), hallux valgus angle ( P = .003), and tibial sesamoid position ( P = .013); however, mean radiographic results were within the normal range for both groups. There were no intergroup differences for either the first metatarsal bone length ( P = .172) or shortening ( P = .621). No significant difference in MOXFQ ( P = .525) was evident between the groups at 3-year follow-up. In satisfaction analysis, 82.6% of the moderate group reported good to excellent results, as did 81.0% of the severe group ( P = .815). A total of 7 complications were reported in each group ( P = 1.000). Conclusion: The present study showed that midterm mean radiographic results of both moderate and severe hallux valgus treated by EDCO with DSTR were favorable, and those values were within the normal range. Clinical outcomes were comparable between the 2 groups, including overall efficacy. Based on these results, we recommend EDCO with DSTR as an efficient and reliable operative option for both moderate and severe hallux valgus. Level of Evidence: Level III, retrospective comparative study.

We retrospectively evaluated the results of 50 hallux valgus reconstructions in 36 patients for moderate to severe deformities, performed by the senior author (F. M. T.). All feet were treated at the metatarsophalangeal joint with a distal soft tissue realignment. The first 25 feet were corrected proximally with a crescentic osteotomy fixed with an AO screw; these cases had an average follow-up of more than 5 years (range, 40–141 months). The second 25 feet underwent a basal osteotomy with a proximally directed chevron osteotomy; these cases had an average follow-up of 21.4 months (range, 12–33 months). The average hallux valgus correction in the crescentic osteotomy group went from 37.6° to 11.4°, and in the chevron osteotomy group, the hallux valgus angle was reduced from 31.3° to 11.6°. The intermetatarsal angle in the crescentic group was corrected from 16.2° to 6°, and in the chevron group the intermetatarsal angle was reduced from 15.1° to 5.4°. The fibular sesamoid subluxation was reduced from 92% to 24% in the crescentic group and from 88% to 18% in the chevron group. All patients were assessed using the American Orthopaedic Foot and Ankle Society scale, in which 100 points are used to compare pre- and postoperative pain, function and range of motion, shoewear comfort and activity levels, and alignment. In the crescentic group, the score improved from 46.8 points to 93.1 points; in the chevron group, the score changed from 53.4 points to 92.7 points. In all parameters studied, there were no statistically significant differences using the Student's t-test. We conclude that the two operative techniques offer equivalent results, which are excellent and predictable. The proximal chevron osteotomy is technically easier, eliminates the proximal dorsal scar, and does not require postoperative metal removal.
