Objective: To evaluate radiographic outcomes in patients undergoing minimally invasive Chevron/Akin osteotomy (MICA) for hallux valgus correction. Methods: We have treated 31 patients (40 feet). Preoperative and postoperative hallux metatarsophalangeal angles (hallux valgus angles, HVA), intermetatarsal angles (IMA) between the first and second metatarsals, and distal metatarsal articular angles (DMAA) were followed up for 12 months. Results: The mean age of the patients was 53.2 years. Mean preoperative HVA, IMA, and DMAA values were 28.85°, 15.38°, and 14.35°, respectively. The mean postoperative angles measured after 1 year were 10.60°, 7.95°, and 7.48°. Improvements in HVA, IMA, and DMAA values showed statistical relevance. There were no losses in angular parameters during follow-up. Conclusion: The radiographic outcomes in patients undergoing MICA osteotomy for hallux valgus correction followed up for 12 months showed significant improvements and no recurrence of the deformity. Our results suggest that this technique is effective for correcting hallux valgus. Level of Evidence III; Therapeutic Studies; Comparative Retrospective Study.

Background:Hallux valgus is a multiplanar deformity of the first ray. Traditional correction methods prioritize the transverse plane, a potential factor resulting in high recurrence rates. Triplanar first tarsometatarsal (TMT) arthrodesis uses a multiplanar approach to correct hallux valgus in all 3 anatomical planes at the apex of the deformity. The purpose of this study was to investigate early radiographic outcomes and complications of triplanar first TMT arthrodesis with early weightbearing.Methods:Radiographs and charts were retrospectively reviewed for 57 patients (62 feet) aged 39.7 ± 18.9 years undergoing triplanar first TMT arthrodesis at 4 institutions between 2015 and 2017. Patients were allowed early full weightbearing in a boot walker. Postoperative radiographs were compared with preoperative radiographs for hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), and lateral round sign. Any complications were recorded.Results:Radiographic results demonstrated significant improvements in IMA (13.6 ± 2.7 degrees to 6.6 ± 1.9 degrees), HVA (24.2 ± 9.3 degrees to 9.7 ± 5.1 degrees), and TSP (5.0 ± 1.3 to 1.9 ± 0.9) from preoperative to final follow-up ( P < .001). Lateral round sign was present in 2 of 62 feet (3.2%) at final follow-up compared with 52 of 62 feet (83.9%) preoperatively. At final follow-up, recurrence was 3.2% (2/62 feet), and the symptomatic nonunion rate was 1.6% (1/62 feet). Two patients required hardware removal, and 2 patients required additional Akin osteotomy.Conclusion:Early radiographic outcomes of triplanar first TMT arthrodesis with early weightbearing were promising with low recurrence rates and maintenance of correction.Level of Evidence:Level IV, retrospective case series.

Objective: To present the clinical and radiographic results of surgical treatment of patients with moderate to severe hallux valgus (HV) by minimally invasive Chevron - Akin osteotomy (MICA). Methods: The case series comprises 25 patients (30 feet) with diagnoses of moderate to severe HV treated surgically with the MICA technique. All patients answered the American Orthopedic Foot and Ankle Score (AOFAS) and rated pain on visual analogue scale (VAS) at preoperative assessment and at the last follow-up consultation. Radiological assessment included measurement of the valgus angles of the hallux (HVA) and the 1st and 2nd ray intermetatarsal angle (IMA). Complications and satisfaction ratings were also documented. Results: Mean follow-up was 14.6 months. Mean AOFAS increased from 42.8 to 90 and VAS reduced from 8.6 to 1.7. Mean HVA reduced from 31.7o to 8.4o and IMA from 14o to 5o. All these improvements were statistically significant (p<0.001). The most common complication observed was discomfort caused by hardware, affecting five feet (16.6%). Two patients (6.6%) had transitory neurapraxia and one patient (3.3%) developed reflex sympathetic dystrophy. There were no cases of infection, relapse, pseudarthrosis, or malunion of osteotomies. Subjective satisfaction ratings classified 93.3% of results as good or excellent. Conclusion: Minimally invasive Chevron-Akin osteotomy is a safe and reproducible technique that achieves good clinical and radiographic results for treatment of moderate to severe hallux valgus.

Category: Bunion Introduction/Purpose: Minimally invasive surgical techniques have challenged objectives in hallux valgus surgery, attempting to obtain good clinical outcomes with the least damage to anatomic structures, low complication rates, short time of surgery, cosmetic advantages and an earlier recovery. However, because patients with generalized ligamentous laxity have a major risk for recurrence, arthrodesis of the first tarsometatarsal (TMT) joint is an established method for the surgical treatment of the patients with generalized ligamentous laxity. This study aims to investigate the clinical and radiographic outcomes of joint-preserving minimally invasive distal metatarsal osteotomy in moderate hallux valgus patients with generalized ligamentous laxity. Methods: Thirty-two feet from 29 patients were involved prospectively with mean follow-up of 16.8 (range, 10 – 26) months. Generalized ligamentous laxity was assessed in all patients and the patients were divided into two groups (16: 16) with the result. Clinical outcomes were assessed using visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score and Foot and Ankle Outcome Score (FAOS). Radiographic parameters were evaluated by preoperative and postoperative weight bearing radiographs. Results: Mean tourniquet time was 30.4 (range, 19 – 44) minute and additional procedures were required in 6 cases in each group. The mean VAS (p<0.001), AOFAS score (p<0.001) and three FAOS subscales (Pain, Symptoms and Quality-of-Life) (p=0.003, p=0.002 and p<0.001) improved significantly at the last follow-up. Significant corrections in the hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA) and sesamoid reduction were obtained at the last follow-up (p<0.001). Relative first metatarsal length was decreased 2.8% from preoperative length (p<0.001). No other radiographic outcomes showed significant difference between the 2 groups but the mean relative first metatarsal length was shorter in the group without generalized ligamentous laxity (p=0.014, respectively) at the last follow-up. Conclusion: Despite the patients without generalized ligamentous laxity tended to have shorter first metatarsal bone postoperatively, minimally invasive distal metatarsal osteotomy yielded substantial clinical and radiological results without any recurrence or fixation failure. This procedure can be a reasonable alternative to first TMT arthrodesis in patients with moderate hallux valgus even with generalized ligamentous laxity.

Background: The objective of this study was to report the results of a new minimally invasive Achilles reconstruction technique and to assess the perioperative morbidity, medium- to long-term outcomes, and functional results. Methods: Our series was comprised 14 patients (11 men and 3 women), with a mean age of 45.6 years at surgery. Each patient had a chronic Achilles tendon rupture. The mean interval from rupture to surgery was 5.5 months (range, 2-10). The mean total follow-up was 30.1 months (range, 12-78). All patients were operated with a central turndown flap augmented with free semitendinosus tendon graft and percutaneous sutures in a minimally invasive approach assisted by endoscopy. The patients underwent retrospective assessment by clinical examination, the American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hindfoot score, and the Achilles Tendon Total Rupture Score (ATRS). Paired t tests were used to assess the preoperative and postoperative AOFAS scores, ATRS scores, and ankle range of motion. Results: The length of the defect ranged from 3 to 8 cm (mean, 5.1), while the length of the turndown flap ranged from 8 to 13 cm (mean, 10.1). The mean AOFAS score improved from 64.5 points preoperatively to 96.9 points at last follow-up. The mean ATRS score improved from 49.4 preoperatively to 91.4 points at last follow-up. None of the patients developed a wound complication. No patient had a rerupture or sural nerve damage. Conclusion: All patients in our study had a favorable outcome with no complications. We believe that with this triple-repair technique, one can achieve a strong and robust repair such as in open surgery while at the same time reducing the incidence of complications. Level of Evidence: Level III, retrospective comparative study.

Background: Hallux valgus recurrence is an unsatisfactory complication, with many causes postulated. This study investigated the effect of pes planus on recurrence after scarf osteotomy. Methods: A total of 183 feet were retrospectively reviewed. All patients were treated with a scarf osteotomy and if required Akin osteotomy. We measured preoperative lateral talus first metatarsal angle (T1MA) to study pes planus; an angle of under −4 degrees was considered pes planus. We measured pre and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), and sesamoid location. In total 164 feet were suitable for inclusion, with follow-up of at least 6 months (10 males and 154 females, mean age: 52 years). Results: Recurrence frequency (HVA greater than 15 degrees) was 27 feet (16%). Hallux valgus recurrence was not influenced by gender ( P value = .66) or preoperative IMA ( P value = .48). Preoperative HVA greater than 35 degrees was associated with increased frequency of recurrence ( P value = .004). Those with T1MA less than −10 degrees demonstrated progression in HVA and deterioration in sesamoid location up to 6 months postoperatively ( P value = .038). HVA did not progress beyond 6 months. The prevalence of recurrent hallux valgus with normal T1MA was 1%, in T1MA −4 to −10 degrees it was 29% and in T1MA less than −10 degrees it was 47% ( P value <.001). Breaks in T1MA less than −4 degrees were found at the naviculocuneiform joint in 68% of feet in this series. Conclusion: The prevalence of hallux valgus recurrence correlated with the severity of pes planus. Level of Evidence: Level III, retrospective cohort study.

Background: This study was aimed at assessing clinical and radiographic outcomes of the Minimally Invasive Intramedullary Nail Device (MIIND) to correct moderate to severe hallux valgus (HV) and the long-term persistence of its effects. Methods: This case series study involved 100 patients, 84 women and 16 men (mean age, 59 years), who underwent the MIIND procedure with a mean follow-up of 97 months. Assessment was performed preoperatively, postoperatively, at 6 and 12 months, and at last follow-up. Clinical outcomes were evaluated with American Orthopaedic Foot & Ankle Society (AOFAS) scores, visual analog scale (VAS), and patient satisfaction. Intermetatarsal angle (IMA), metatarsophalangeal hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), and tibial sesamoid position were assessed. Statistical analysis was performed. Results: The mean AOFAS score improved from 57.9 to 90.5 points, VAS scale was 1.5 ± 2.0, and patients’ satisfaction was 8.7 ± 1.4. The mean correction of the HVA and IMA showed a significant correction; however, the effect of time was not statistically significant on DMAA. Sex ( P = .047), severity ( P = .050), associated procedures ( P = .000), and preoperative angle ( P = .000) showed significant association with HVA correction and its persistence over time. Age was not statistically significant. Complications were 9 cases of superficial wound infection and 6 recurrences. Conclusions: The MIIND technique proved a viable procedure to correct moderate to severe HV with a low rate of complications and recurrence, producing significant correction of most radiographic parameters assessed and their persistence, even at long term. Level of Evidence: Level IV, case series study.

Introduction: The purpose of the present study is to evaluate the clinical and radiographic results of simultaneous surgical correction for bilateral hallux valgus compared with unilateral correction using percutaneous forefoot surgery techniques (PFS). Material and Methods: A prospective cohort study of 82 patients (106 feet). The mean follow-up was 58.7[Formula: see text][Formula: see text][Formula: see text]1.5 months (range 22.3 to 112.1). Patients were divided into two groups, unilateral surgical group (group U, 58 feet) and simultaneous bilateral surgical group (group B, 48 feet). Results: Preoperative mean visual analog scale (VAS) was 6.2 points in group U and 6.3 in group B ([Formula: see text]), at the last follow-up it decreased in both groups (1.6 group U and 1.8 group B, [Formula: see text]). AOFAS score improved from approximately 50 points preoperative in both groups, to 88 at the last follow-up. Mean hallux valgus angles in groups U and B changed from 34.7[Formula: see text] and 34.3[Formula: see text] preoperatively ([Formula: see text]), to 21.3[Formula: see text] and 22.4[Formula: see text] follow-up, respectively ([Formula: see text]). With the numbers available, no significant inter-group differences were observed in clinical and radiographic outcomes. Conclusions: PFS is a valid procedure for outpatient simultaneous surgical correction in patients with bilateral hallux valgus. Level of Evidence: II Prospective Comparative Cohort Study.

Background: Bipartite hallucal sesamoids are often found in patients with hallux valgus. However, it is unknown whether bipartite hallucal sesamoids affect the results of hallux valgus surgery or not. The purpose of the present study was to evaluate the outcomes of chevron osteotomy for hallux valgus with and without bipartite hallucal sesamoid. Methods: A total of 152 patients (168 feet) treated with distal or proximal chevron osteotomy for hallux valgus constituted the study cohort. The 168 feet were divided into 2 groups: bipartite hallucal sesamoid (31 feet) and without bipartite hallucal sesamoid (137 feet). Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), tibial sesamoid position, and first metatarsal length were measured for radiographic outcomes and the American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal (MTP-IP) score was measured for clinical outcomes. Results: All radiographic measurements and the AOFAS score showed significant ( P < .05) improvement at the time of final follow-up compared with preoperative measurements in both groups. No significant differences ( P > .05) were found between the 2 groups in terms of HVA, IMA, DMAA, tibial sesamoid position, metatarsal shortening, and AOFAS score on final follow-up. Conclusions: This study suggests that bipartite hallucal sesamoids do not affect the results of hallux valgus surgery. Level of Evidence: Level III, retrospective comparative study.

Abstract Background Hallux valgus is a common foot deformity that leads to functional disability with serious sequelae. Minimally invasive surgery is often used to treat hallux valgus in order to reduce wound complications and improve recovery time. The objective of this study was to compare a Simple, Effective, Rapid, Inexpensive (SERI) technique with a simple Chevron technique in patients with minimum of one-year follow. Methods and Materials Between the years 2014-2015 we performed a prospective study comparing the SERI minimally invasive technique to treat symptomatic hallux valgus with a standard chevron osteotomy technique. All procedures were performed by a single fellowship trained foot and ankle surgeon. Twenty-one patients were randomized to the SERI cohort and 15 to the standard Chevron technique. Results The mean pre-operative intermetatarsal angle (IMA) of the SERI group was 14.8 ± 1.9 (11.9 - 22.9). The mean pre-operative IMA of the Chevron control group was 13.3 ± 2.3 (10.4 -18.2) (p = 0.038). The mean IMA two weeks after surgery was 6.0 ± 2.3 (2.4-12) in the SERI group, and 6.1 ± 3 (2.6-13.1) in the control group. At the two week and one year follow up, there was no significant difference found in the IMA between the two groups (p = 0.871). Neither groups reported symptomatic transfer metatarsalgia throughout the follow up period. The SERI group had increased metatarsophalangeal joint (MTPJ) motion (p < 0.001) however, all other parameters with similar. Conclusion The SERI technique provided comparable outcomes at up to one year follow up when compared to a standard Chevron osteotomy for moderate hallux valgus. This study demonstrated good reproducible results using the SERI technique for moderate hallux valgus.

Background: Few studies have reported results of minimally invasive chevron Akin osteotomy (MICA) for moderate to severe hallux valgus correction. This study aims to evaluate MICA for moderate to severe hallux valgus radiographically and clinically. Methods: Forty feet were prospectively reviewed. Twenty-eight feet (70%) had a severe deformity (hallux valgus angle (HVA) ≥40° and/or first intermetatarsal angle (IMA) ≥18°). We measured HVA, IMA, lateral shape of the metatarsal head (round sign), tibial sesamoid position, first metatarsal shortening on anteroposterior weightbearing radiographs, and inclination angle of first metatarsal on lateral weightbearing radiographs. We evaluated the Japanese Society for Surgery of the Foot hallux scale and Self-Administered Foot Evaluation Questionnaire responses preoperatively and at the most recent follow-up. Results: All measurements except shortening and inclination angle improved significantly. Both clinical scale and all subscores significantly improved. Conclusions: MICA improved moderate to severe hallux valgus both radiographically and clinically. Level of Evidence: Level IV: case series
