Retrospective Analysis of Radiographic Outcomes After Closing Base Wedge Osteotomy for Correction of Bunion Deformity.

BACKGROUND: Closing base wedge osteotomy (CBWO) is a common procedure to correct severe bunion deformities with high intermetatarsal angles. There are few data demonstrating the radiographic success of CBWOs. METHODS: We evaluated the radiographic outcomes of a CBWO. The primary aim was to assess the change in elevatus after a CBWO. Secondary aims included measuring the change in hallux abductus (HA) and intermetatarsal angles after the osteotomy. The medical records of 24 consecutive patients across 4 years were reviewed. All of the CBWOs were fixated with either one screw and one Kirschner wire or two screws. We hypothesized that the CBWO would reduce the amount of elevatus present. RESULTS: The mean patient age was 35 years. Average preoperative HA and intermetatarsal angles were 35.2° and 15.7°, respectively. Mean postoperative HA and intermetatarsal angles at last radiographic follow-up were 13.3° and 6.1°, respectively. The change in HA and intermetatarsal angles was 21.9° and 9.6°, respectively. All of the patients achieved clinical union. Mean radiographic follow-up was 6 months; median radiographic follow-up was 5 months. The mean preoperative elevatus measurement was 3.5 mm; the mean postoperative elevatus measurement was 2.0 mm (difference, -1.6 mm; P = .0282), indicating that the osteotomy plantarflexed the first metatarsal. Three patients had radiographic evidence of postoperative elevatus; they were asymptomatic at the last clinical follow-up. CONCLUSIONS: Although clinical concern persists for the development of postoperative elevatus with CBWO, this case series showed plantarflexion of the CBWO. The CBWO is a powerful yet stable procedure for severe bunion deformities and should be viewed as a viable alternative to the Lapidus procedure.

The chevron bunionectomy for moderate to severe hallux valgus deformity: Effects of procedural factors on hallux valgus correction.

BACKGROUND: Effects of procedural factors on chevron bunionectomy outcomes were studied. METHODS: Included were 109 feet with distal chevron osteotomy and preoperative intermetatarsal angle (IMA) greater than 15 degrees. IMA and hallux valgus angles (HVA), release type, fixation, second-digit procedures, and risk factors were evaluated. RESULTS: Eighty-three percent (91/109 feet) had satisfactory outcomes; nine had moderate pain. From preoperative, IMA improved 7.2 and HVA 20.5 degrees. Risk factors or second-digit procedures had no effect. Lateral release improved IMA (p < 0.01), with no difference between open lateral and transarticular release; 86% percent (64/74) were satisfied with open lateral release compared with 83% (19/23) and 66% (8/12) with no release and transarticular release, respectively. Fixation did not affect outcomes. CONCLUSION: Chevron bunionectomy corrected IMA and HVA to normal with few complications. Lateral release increased IMA correction. Transarticular release had lower satisfaction than open lateral release or no release. LEVEL OF EVIDENCE: Level III, retrospective.

Are Radiographs Associated With Patient Satisfaction After Scarf Bunionectomy?

There are over 350,000 bunion surgeries performed in the USA annually, making it one of the most common elective forefoot surgeries. Studies have suggested that as many as 10% of patients remain dissatisfied after bunion surgery. The purpose of this study is to evaluate if radiographic variables are associated with patient satisfaction at 1 year postoperatively. We performed a secondary analysis of prospectively collected data on 69 consecutive adult patients (mean age 45 ± 14 years, 91% female [63/69]) who underwent isolated hallux valgus surgery from January 2016 to January 2017. Subjects completed a standardized 4-item survey inquiring about their satisfaction with regards to pain relief, overall operative result, cosmetic appearance, and ability to wear desired shoe gear. Conventional radiographic indices for hallux valgus were examined preoperatively and 3 months postoperatively. An association model using backward stepwise logistic regression was utilized to determine which variables, if any, are most important in explaining patient satisfaction after surgery. Sixty-nine subjects completed the 4-item satisfaction survey with 53.6% (37/69) of subjects answering they were fully satisfied on all aspects of the survey at 12 months postoperatively. In the final regression model, no radiographic or demographic variables were associated with patient satisfaction including shoe gear, cosmetic appearance, pain relief, and overall operative result. Radiographic variables did not appear to be associated with patient satisfaction at one year postoperatively in our study. Factors such as quality of life, anxiety levels, fear of surgery, and/or preoperative expectations may offer more insight into satisfaction; however, further research should be performed to examine this further.

Influencia del tratamiento quirúrgico para el hallux abductus valgus en la movilidad del primer radio / Influence of surgical treatment of hallux abducto-valgus on first ray mobility

Objetivo: El objetivo principal de este trabajo es determinar la variación de movilidad pre y postquirúrgica del primer radio. Pacientes y métodos: El diseño corresponde a un estudio prospectivo de series de casos en pacientes sometidos a cirugía de hallux valgus. Se valoró en 13 pies la movilidad del primer radio con el medidor del primer radio, la flexo-extensión de la primera articulación metatarsofalángica, el ángulo de Clarke y el “Arch Index” en pedigrafías, los ángulos hallux valgus e intermetatarsal I-II en radiografías dorsoplantares en carga, y la postura general del pie mediante el “Foot Posture Index” antes y después de ser sometidos a cirugía de hallux valgus. Todo ello con un periodo de seguimiento de 6 meses. Resultados: El rango total de movilidad del primer radio pasó de 11.74 ± 1.88 mm a 6.72 ± 2.20 mm; y el de la primera articulación metatarsofalángica pasó de 79.62° ± 22.33° a 48.69° ± 18.69° tras la cirugía. Los ángulos radiográficos de hallux valgus y ángulo intermetatarsal disminuyeron una media de 19.07° ± 8.20° y 7.23° ± 2.97°, respectivamente. El ángulo de Clarke cambió de 41.31° ± 10.79° a 38.31° ± 11.00°. El “Arch Index” cambió de 0.24 ± 0.06 a 0.25 ± 0.05. Y el “Foot Posture Index” pasó de 6.70 ± 3.33 de media antes de la cirugía a 5.46 ± 3.86 tras la misma. Conclusión: En los participantes incluidos en este estudio se observó una disminución generalizada de todas las variables examinadas tras la cirugía, a excepción de los parámetros valorados en las pedigrafías, que no llegaron a presentar diferencias relevantes.(AU)

Objectives: The main aim of this work is to determine the variation of first ray mobility before and after surgery. Patients and methods: The design corresponds to a prospective case series of patients operated of hallux valgus. A total of 13 feet have been included in this study. Measurements of the first ray mobility were obtained using the first ray mobility measurer. Furthermore, we assess the flexo-extension of the first metatarsophalangeal joint. The Clarke’s angle and the Arch Index were evalued on weightbearing footprints. The hallux valgus angle and intermetatarsal I-II angle were made on weightbearing dorsal-plantar projection radiographs. And finally, the general posture of the foot was quantified using the Foot Posture Index. All this with pre and post measurements of hallux valgus surgery and with a follow-up period of 6 months. Results: The total range of motion of the first ray decreased from 11.74 ± 1.88 mm to 6.72 ± 2.20 mm; and the range of motion of the first metatarsophalangeal joint underwent from 79.62° ± 22.33° to 48.69° ± 18.69° after surgery. The hallux valgus angle and intermetatarsal I-II angle decreased by a mean of 19.07° ± 8.20° and 7.23° ± 2.97°, respectively. The Clarke’s angle changed from 41.31° ± 10.79° to 38.31° ± 11.00°. The Arch Index changed from 0.24 ± 0.06 to 0.25 ± 0.05. And the Foot Posture Index went from 6.70 ± 3.33 before surgery to 5.46 ± 3.86 after it. Conclusion: In the participants included in this study, a generalized decrease was observed in all the examined variables after surgery, except for the parameters assessed in the pedigraphs, which did not present relevant differences.(AU)

[Analysis of risk factors and progress on revision surgery for postoperative recurrence of hallux valgus].

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.

Managing Complications of Foot and Ankle Surgery: Hallux Valgus.

Hallux valgus deformity is nowadays one of the most common and symptomatic disorders affecting the foot. Surgical corrections of hallux valgus deformity are among the most common orthopedic procedures. Despite the general high success rate complications can occur. The treatment of complications start before the first incision has been performed by thorough preoperative planning and choice of the right procedure. Once the complication is evident, thorough planning is necessary to address the patient's individual needs. In this paper the treatment of recurrent hallux valgus, hallux varus, malunion, and avascular necrosis are discussed.

The influence of concomitant hammertoe correction on postoperative outcomes in patients undergoing hallux valgus correction.

BACKGROUND: Patients with hallux valgus often develop secondary hammertoe deformities of the lesser toes. Operative management of bunions with hammertoe can be more extensive; however, it is unclear whether this affects patient-reported outcomes. The aim of this study was to compare postoperative patient-reported outcome measures and radiographic outcomes between patients who underwent isolated bunion correction and patients who underwent simultaneous bunion and hammertoe correction. METHODS: Preoperative, postoperative, and change in Patient-Reported Outcomes Measurement Information System (PROMIS) scores were compared between patients who underwent isolated hallux valgus correction and those who underwent concomitant hammertoe correction. Radiographic measures including hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal-articular angle (DMAA), and Meary's angle were also compared. Targeted minimum-loss estimation (TMLE) was used for statistical analysis to control for confounders. RESULTS: A total of 221 feet (134 isolated bunion correction, 87 concomitant hammertoe correction) with a minimum of 12 months follow-up were included in this study. Both cohorts demonstrated significant improvements in the physical function, pain interference, pain intensity, and global physical health PROMIS domains (all p < 0.001). However, patients in the concomitant hammertoe cohort had significantly less improvements in pain interference and pain intensity (p < 0.01, p < 0.05 respectively). The concomitant hammertoe cohort also had significantly higher postoperative pain interference scores than the isolated bunion cohort (p < 0.01). Radiographic outcomes did not differ between the two groups. CONCLUSION: While both isolated bunion correction and concomitant hammertoe correction yielded clinically significant improvements in patient reported outcomes and normalized radiographic parameters, patients undergoing simultaneous bunion and hammertoe correction experienced substantially less improvement in postoperative pain-related outcomes than those who underwent isolated bunion correction.

Clinical Outcomes of Scarf-Akin Osteotomy for Hallux Valgus With Simultaneous Bunionette Correction: A Propensity Score-Matched Cohort Analysis.

Hallux valgus and bunionette (Tailor's bunion) deformities are debilitating forefoot deformities that may occur together. Successful outcomes of surgery for either pathology have been well-described; however, the literature is sparce on outcomes of patients undergoing simultaneous surgery for both deformities. Between 2007 and 2018, 429 patients underwent a scarf-Akin osteotomy, and 20 patients underwent simultaneous bunionette surgery. Propensity score matching was used to match the scarf + bunionette group in a 1:2 ratio to a corresponding scarf only group using logistic regression. Their hallux and fifth metatarsal visual analogue scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) Hallux Metatarsophalangeal-Interphalangeal Scale, Short Form-36 (SF-36), expectations and satisfaction scores were recorded at preoperative, 6-month and 2-year intervals. There were no differences in baseline characteristics between groups after matching (p > .05). At 6 months, the scarf + bunionette group had a significantly worse fifth metatarsal AOFAS (80.7 vs 92.9, p = .002) and VAS (1.5 vs 0.1, p = .008). However, at 2 years, greater improvements in the scarf + bunionette group resulted in no significant differences for fifth metatarsal AOFAS and VAS. The scarf + bunionette group had better SF-36 scores in the domains of physical functioning, bodily pain, general health and mental health (p < .05). Scarf + bunionette patients trended toward higher satisfaction (100.0% vs 85.0%, p = .165) and expectation fulfilment (95.0% vs 80.0%, p = .249) at 2 years, although not significant with the available numbers. In patients with similar baseline hallux and fifth metatarsal pain and function, simultaneous surgery and a scarf osteotomy alone result in similar improvements to pain and function at 2 years. However, patients who undergo both procedures have higher quality of life scores.

Simultaneous bilateral hallux valgus surgery: Percutaneous or conventional? Early results of a matched study from a tertiary institution.

BACKGROUND: Hallux valgus is bilateral in up to 84 % of cases. In the setting of simultaneous bilateral correction, we aim to evaluate if minimally invasive percutaneous surgery (MIS) provides any advantage compared to conventional open surgery. METHODS: 52 feet (26 patients) undergoing simultaneous bilateral MIS surgery were matched by severity of deformity to 52 feet (26 patients) undergoing simultaneous conventional open surgery. Patients were followed for a minimum of six months. Pre- and post-operative radiographs and clinical records were reviewed. RESULTS: There were no significant differences in pre-operative function or pain between both groups. Post-operatively, the mean hallux valgus angle (HVA) was significantly lower in the MIS group. (HVA MIS - 8.6; Open - 11.8, P = 0.013). There were no significant differences in post-operative outcome and patient satisfaction between both groups. CONCLUSION: This study demonstrates that simultaneous bilateral MIS hallux valgus surgery can be considered for patients with bilateral symptomatic hallux valgus.

Weightbearing Computed Tomography and 3-Dimensional Analysis of Mobility Changes of the First Ray After Proximal Oblique Osteotomy for Hallux Valgus.

BACKGROUND: Hypermobility of the first ray has been evaluated using various methods and has conventionally been considered to be involved in the pathology of hallux valgus. We hypothesized that hypermobility of the first ray in hallux valgus could be decreased by simply correcting foot alignment without arthrodesis. This study sought to evaluate first-ray mobility using weightbearing computed tomography (CT) before and after proximal oblique osteotomy and also in healthy volunteer's feet. METHODS: Subjects were 11 feet of 11 patients with primary hallux valgus who underwent surgery with a plantarly applied anatomic precontoured locking plate and 22 feet of 11 matched healthy volunteers. We performed nonweightbearing and weightbearing (using a load equivalent to body weight) CT scans using an original loading device preoperatively and 1-1.5 years postoperatively. Three-dimensional displacement of the distal bone relative to the proximal bone was quantified for each joint of the first ray by comparing nonweightbearing and weightbearing CT images. RESULTS: At baseline, there were significant differences in hallux valgus angle (P < .001) and 1-2 intermetatarsal angle (P < .001) between healthy volunteer's feet and preoperative hallux valgus feet. Hallux valgus angle (P < .001) and 1-2 intermetatarsal angle (P < .001) differed significantly between before and after surgery. All first ray joint displacement under loading decreased postoperatively to within 2° of that in healthy volunteer's feet and showed no significant difference between postoperatively hallux valgus feet and healthy volunteer's feet (P > .05). CONCLUSIONS: We found that first metatarsal osteotomy even without arthrodesis corrected deformity and decreased mobility of the first ray after hallux valgus surgery. LEVEL OF EVIDENCE: Level III, case-control study.

Is obesity a risk factor in percutaneous hallux valgus surgery?

BACKGROUND: Obesity and its relationship with higher rate of complications in orthopedic surgeries have been reported. There is no evidence of the relation between obesity and percutaneous foot surgery. Our objective was to evaluate obesity as a risk factor for complications and reoperations in percutaneous surgery of the hallux valgus. METHODS: A total 532 feet were retrospectively reviewed in which a percutaneous hallux valgus correction was performed. Complications and surgical reoperations were recorded. Patients were divided into 2 groups: BMI less and greater than 30kg/m2. RESULTS: There were no differences in the rate of complications or reoperations. The total complication rate was 8%. Obesity as an isolated risk factor, presented aOR=1.14 (95%CI 0.54-2.4, p=.714). The overall rate of reoperations was 9%. Obesity presented an aOR=0.64 (95%CI 0.27-1.49, p=.31). CONCLUSION: Obesity has not been associated with a higher rate of complications and reoperations in percutaneous hallux valgus surgery. It is a safe procedure and BMI should not influence in the prognosis. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Pes Planus Deformity and Its Association With Hallux Valgus Recurrence Following Scarf Osteotomy.

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.

Revision of Malaligned Lapidus and Nonunited Lapidus.

"Lapidus arthrodesis is becoming more of a common procedure for treatment of hallux valgus deformities. Like other procedures, complications are possible. The common complications associated with Lapidus arthrodesis procedures include nonunion and malunion. Malunion is typically broken down into recurrence, elevated first ray, shortened first ray, or plantarflexed first ray. This article discusses these common complications after Lapidus arthrodesis.

Role of Patient-Reported Outcome Measures on Predicting Outcome of Bunion Surgery.

BACKGROUND: Prior studies have suggested preoperative patient-reported outcome scores could predict patients who would achieve a clinically meaningful improvement with hallux valgus surgery. Our goal was to determine bunionectomy-specific thresholds using Patient-Reported Outcomes Measurement Information System (PROMIS) values to predict patients who would or would not benefit from bunion surgery. METHODS: PROMIS physical function (PF), pain interference (PI), and depression assessments were prospectively collected. Forty-two patients were included in the study. Using preoperative and final follow-up visit scores, minimally clinically important differences (MCID), receiver operating characteristic (ROC) curves, and area under the curve (AUC) analyses were performed to determine if preoperative PROMIS scores predicted achieving MCID with 95% specificity or failing to achieve an MCID with 95% sensitivity. RESULTS: PROMIS PF demonstrated a significant AUC and likelihood ratio. The preoperative threshold score for failing to achieve MCID for PF was 49.6 with 95% sensitivity. The likelihood ratio was 0.14 (confidence interval, 0.02-0.94). The posttest probability of failure to achieve an MCID for PF was 94.1%. PI and depression AUCs were not significant, and thus thresholds were not determined. CONCLUSION: We identified a PF threshold of 49.6, which was nearly 1 standard deviation higher than previously published. If a patient is hoping to improve PF, a patient with a preoperative t score >49.6 may not benefit from surgery. This study also suggests the need for additional research to delineate procedure-specific thresholds. LEVEL OF EVIDENCE: Level III, retrospective comparative series.

Validating the Foot and Ankle Outcome score for measuring foot dysfunction among hallux valgus surgery patients using item response theory.

BACKGROUND: There is an absence of high quality research validating instruments that measure foot and ankle related quality of life among hallux valgus (bunion) patients' perspectives. The Foot and Ankle Outcome Scale is a patient-reported outcome instrument, that when administered to patients with symptomatic hallux valgus, provides a patient-centric perspective of their foot function. The aim of this study is to assess the psychometric properties of the instrument's five subscales among preoperative bunion surgery patients. METHODS: The Foot and Ankle Outcome Scale instrument measures Pain, Symptoms, Activities of Daily Living, Sport and Recreational Activities and Foot/Ankle Related Quality of Life. Preoperative data is collected from a sample of patients scheduled for surgical treatment of their condition in Vancouver, Canada. Classical and item response theory methods are used to report on reliability, validity and differential item functioning among subgroups. RESULTS: This study included 249 surveys, representing an overall response rate of 44.1% among 564 eligible patients. The instrument demonstrated high reliability for all subscales, though 18 items across subscales, exhibited poor discrimination between item levels. Four items score differently according to patients' sex and one item scored differently by age. CONCLUSIONS: The instrument measures five domains of health important to bunion patients. These findings suggest that the current instrument can be used with an understanding of its limitations, including redundant questions and sex-based differences. Future research should revise a number of items. The results highlight the importance of the psychometric analyses of instruments in specific patient populations.

Radiographic Outcomes of a Percutaneous, Reproducible Distal Metatarsal Osteotomy for Mild and Moderate Bunions: A Multicenter Study.

Hallux valgus is a prevalent condition. Many open surgical methods of correction have been described. We performed a percutaneous, extra-articular distal metatarsal osteotomy for mild to moderate bunion deformity. The minimally invasive technique was used in 217 feet (180 patients; age 49 ± 4.7 years, mean ± standard deviation) at 4 centers in North America (Center 1: November 2012 to March 2017; Center 2: January 2010 to May 2016; Center 3: October 2013 to June 2016; Center 4: January 2015 to June 2017). The procedure was used in simultaneous bilateral cases in 28 patients (15.6%) and in nonsimultaneous bilateral cases in 9 patients (5.0%). Immediate postoperative weightbearing was used in all cases. The mean preoperative intermetatarsal angle, hallux abductus angle, and tibial sesamoid position were 14.6° ± 3.5°, 30.7° ± 7.8°, and 5.4 ± 1.4, respectively. At final follow-up of 9.3 ± 6.1 months, the mean intermetatarsal angle, hallux abductus angle, and tibial sesamoid position were 4.7° ± 2.8°, 8.4° ± 6.1°, and 2.0 ± 1.0, respectively (p < .0001 for all comparisons). No major complications were noted. All 217 osteotomies achieved union; 3 feet (1.4%) in 3 patients (1.7%) experienced asymptomatic malunion. Superficial pin-site infection was seen in 42 (19.4%) of the 217 feet (39 patients, 21.7%). The radiographic results of this percutaneous technique appear to be reproducible across multiple centers, and the technique is useful when correcting intermetatarsal and hallux abductus angles. This percutaneous osteotomy for realignment of the first ray allows immediate postoperative weightbearing and, in this initial review, appears to be safe and effective, even in simultaneous bilateral cases.

Management of Juvenile Hallux Valgus Deformity: the role of combined Hemiepiphysiodesis.

BACKGROUND: This study aimed to investigate the efficacy of percutaneous hemiepiphysiodesis for gradual correction of symptomatic juvenile hallux valgus (HV) deformity. METHODS: Between 2012 to 2014, 24 patients with symptomatic juvenile HV were treated by combined percutaneous medial drilling hemiepiphysiodesis of the first proximal phalanx and lateral transphyseal screw hemiepiphysiodesis of the first metatarsal at our institution. Twenty-one of 24 patients fulfilled inclusion criteria had a complete radiological and clinical follow-up of at least 2 years. Preoperative and postoperative radiographs of the feet were reviewed for measurements of hallux valgus angle (HVA), intermetatarsal angle (IMA), proximal metatarsal articular angle (PMAA), proximal phalangeal articular angle (PPAA), and metatarsal length ratio (MTLR). Clinical outcomes were assessed using the AOFAS hallux metatarsophalangeal-interphalangeal score. RESULTS: The study included 21 consecutive patients (37 ft) for analysis. The mean age at surgery was 12.0 years (SD = 1.3) and mean follow-up after surgery was 35.1 months (SD = 6.0). With the data available, the HV deformity improved in terms of the reduction of HVA by a mean of 4.7 degrees (P < .001) and the reduction of IMA by 2.2 degrees (P < .001). The PMAA and PPAA also improved significantly in the anteroposterior plane; however, the PMAA difference was insignificant in lateral plane as expected. The mean difference in the MTLR was 0.00 (P = .216) which was indicative of no length discrepancy between first and second metatarsals. The AOFAS score increased from 68.7 to 85.2 (P < .001). In correlation analysis, time to physeal closure was significantly correlated with the final HVA change (r = -.611, P = .003). CONCLUSION: Although combined hemiepiphysiodesis does not create a large degree of correction as osteotomy, yet it did improve HV deformity with adequate growth remaining in our series. It is a procedure that can be of benefit to patients with symptomatic juvenile HV from this minimal operative approach before skeletal maturity. LEVEL OF EVIDENCE: Level IV, retrospective case series.
