Category: Bunion Introduction/Purpose: Recurrence of hallux valgus deformity is a common post-operative complication with rates in the literature ranging from 2.7 – 30%. Lateral displacement of the great toe medial sesamoid is correlated with a high recurrence rate, and failure to reduce sesamoid position has been implicated as a risk factor for recurrence due to an uncorrected deforming force. Sesamoid position has been studied in relation with Scarf osteotomy, but not other corrective osteotomies. The goal of this study is to determine the efficacy of the double chevron and Akin osteotomy in reducing the great toe medial sesamoid. Methods: We retrospectively reviewed all patients in the last five years undergoing hallux valgus correction via the double chevron and Akin osteotomy method with pre-operative and post-operative weight bearing radiographs. We measured sesamoid position pre and post-operatively using the Hardy-Clapham (HC) scale of I-VII with V or greater representing a laterally displaced medial sesamoid. We also measured hallux valgus and inter-metatarsal angles. Measurements were made by three authors in orthopedics and one in radiology. We used intra-class correlation coefficient (ICC) to determine inter-observer agreement and establish reliability. With adequate ICC, we could consider the lead author’s measurements as representative of the group. We examined the percent of hallux valgus cases with displaced sesamoids pre-operatively. Next, we determined how many of those cases did we reduce the sesamoids to grade IV or less. Finally, we performed subgroup analysis for pre-operative HC grades V, VI, and VII to determine correction percentage by severity. Results: There were 49 patients with 53 feet treated with the double chevron and Akin osteotomies for hallux valgus correction. Of these, 39 (73.6%) had significant preoperative lateral displacement of the medial sesamoid characterized by HC grade of V or greater. We corrected 30/39 (77.0%) to a reduced position of HC grade IV or less (p-value 0.048). In sub-analysis, we achieved reduction of the medial sesamoid position in 14/14 feet (100%) with HC grade V, 6/9 feet (66.7%) with HC grade VI, and 10/16 feet (62.5%) with HC grade VII (p-value 0.037). The ICC was 0.91 for pre-operative HC scores and 0.79 for post-operative HC scores. Average pre and post-operative HVA was 29.4° and 8.7°, respectively. Average pre and post-operative IMA was 13° and 5.2° respectively. Conclusion: Our study validates the double chevron and Akin osteotomies as effective in correcting sesamoid position. We achieved correction in 30/39 (77%) cases with initial sesamoid displacement. For mild cases of displacement with HC grade V, sesamoid correction was always achieved, and we were likely to achieve correction in the more severe cases of sesamoid displacement with HC grade VI or VII as well. The technique is also effective at reducing HVA and IMA. We had acceptable inter- observer agreement which supports the reliability of our methods. Future studies should examine recurrence rate following the double chevron and Akin osteotomies prospectively.

Increased Risk

Category: Bunion Introduction/Purpose: Factors linked with increased risk of developing Hallux Valgus include; shod footwear, genetic factors, metatarsal morphology, ligamentous laxity and Pes Planus. With regards to Pes planus, it has been suggested that the loss of the medial longitudinal arch in Pes Planus increases Hallux plantar medial pressures and drives deformity during heel rise. There is little in the literature regarding whether Pes Planus is associated with increased recurrence rates. Given this is a potentially modifiable risk factor we believe the risk of recurrence should be studied. This paper reports the results of a retrospective study following up 183 consecutive Hallux valgus cases. The primary objective is to evaluate whether pes planus is associated with increased recurrence following treatment. Methods: Retrospective review of consecutively treated patients from 07/03/2008 to 05/12/2017. Patients were typically followed up for six to twelve months depending on any additional factors that require follow up. X-rays were performed routinely at six weeks, three months and many had x-rays at six and/or 12 months for additional pathology. We examined radiological markers including Sesamoid location (using the Hardy and Clapham Classification), Hallux Valgus Angle (HVA), Intermetatarsal Angle, Meary’s angle and Talonavicular uncovering. 183 cases were reviewed, 12 were excluded due to previously amputated second toes, Hallux Varus, revision surgery and only 6 weeks follow up. This left 171 cases of which 75 had Pes Planus (Meary’s angle < -4°). Results: Table 1 describes the preoperative HVAs we encountered and the correction achieved along with frequencies. Postoperative measurements were taken off weight bearing x-rays. The incidence of recurrent HVA > 15° was significantly higher in those with Meary’s angle < - 4° (Chi-Sq 22.6 P-value 0.000002). Those with a Meary’s angle -20° to -10° had a significantly higher rate of recurrence than ones measuring -10° to -4° (Chi-Sq 9.7 P-value 0.0018 There was no difference in progression of recurrent deformity between those initially corrected to HVA < 15° (Chi-Sq 0.26 P- value 0.61) and those not. Multiple regression analysis revealed there was no meaningful association with sesamoid location or pes planus with recurrence of Hallux Valgus deformity. Conclusion: Our results demonstrate a link between Preoperative Pes Planus deformity and increased recurrence rates of Hallux Valgus deformity following surgery. Consideration of correction of pes planus and appropriate consent of recurrence rates should therefore be undertaken in treatment of hallux valgus in the presence of pes planus

Risk Factor For Recurrence

Abstract Introduction Incomplete correction of the sesamoid position after corrective osteotomy is a risk factor for recurrence of the hallux valgus deformity. This study was done to report the results of sesamoid alignment after chevron osteotomy. Method 92 patients (111 feet) had minimally invasive (MIS) distal chevron osteotomy and release of fibular sesamoid ligaments done, sesamoid position was assessed in the weight-bearing views of the foot, tibial sesamoid position in relation to the mechanical axis of the first metatarsal was classified as grades 0-3 where the normal position was graded (0) and the most lateral sublaxation was graded (3). There were 2 groups; the reduced (grade 0-1) & the dislocated (grade 2,3) groups. Preoperative and post-operative radiographs were compared. Postoperative images were done 6-8 weeks post-operatively to ensure osteotomy healing. Results Sesamoids alignment was corrected following the MIS chevron osteotomy; 84 feet (75.7%) were from the dislocated group and 27 feet (24.3%) were from the reduced group pre-operatively improved to 102 feet (91.9%) reduced and only 9 feet (8.1%) dislocated following the procedure with P-value &lt; 0.00001. To ensure inter-observer reliability, images were assessed by 2 observers with Cohen’s Kappa coefficient 0.477. Conclusions MIS chevron osteotomy can produce significant improvement of sesamoid position which is crucial to prevent recurrence of hallux valgus.

Hallux Valgus Deformity

With the progress of medical treatment for rheumatoid arthritis (RA), several joint-preserving forefoot surgical procedures have been established and performed. In this situation, we have been choosing the combined surgery: modified scarf osteotomy for the great toe and metatarsal shortening offset osteotomy for the lesser toes in RA cases. A retrospective observational study of 53 RA patients (mean follow-up period: 4.6 years) who underwent the surgery was completed. RA foot ankle scores were assessed, using the Japanese Society for Surgery of the Foot (JSSF) standard rating system, and a self-administered foot evaluation questionnaire (SAFE-Q) was also checked to evaluate clinical outcomes. For radiological evaluations, deformity parameters were measured using radiographs of the feet with weight-bearing. JSSF hallux and lesser toes scores and the SAFE-Q score showed significant improvement in all indices. HVA, M1-M2A, M1-M5A, M2-M5A, and sesamoid position were significantly improved after surgery. At the final follow-up, the hallux valgus deformity had recurred in 4 feet (7.5%), and hallux varus deformity had developed in 8 feet (15.1%). No case of recurrent hallux valgus deformity required revision surgery. Recurrence of dorsal dislocation/subluxation of the lesser toe MTP joint was seen in 6 feet (11.3%) after surgery. A combination of modified scarf osteotomy for the great toe and modified metatarsal shortening offset osteotomy for the lesser toes is one of the novel surgical procedures for rheumatoid forefoot deformity. Preoperative disease activity of RA negatively affected the clinical score of the hallux. The spread of M2-M5A was a risk factor for resubluxation of the lesser toe MTP joint.

Risk Factors For Recurrence

Category: Bunion Introduction/Purpose: The most frequent complication after hallux valgus corrective surgery is recurrence of deformity. Many factors have been identified previously as risk factors for recurrence. Especially, inadequate correction of the distal metatarsal articular angle (DMAA) has been reported one of the surgical risk factors for recurrence. This study aimed to investigate the recurrence rate after hallux valgus correction using Scarf and Akin osteotomy and to identify the significance of postoperative DMAA as a risk factor of recurrence. Methods: We reviewed 87 hallux valgus patients (122 feet) who received Scarf and Akin osteotomy from January 2007 to August 2015. Clinical outcomes were evaluated using VAS and the AOFAS score. Radiological outcome measures included hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA) in serial weight bearing radiograph. Recurrence was defined as more than 20 degrees of HVA in final follow-up radiograph. Radiological factors associated with recurrence including high DMAA were evaluated and analyzed. Results: Mean follow-up duration was 20.6 months (range, 12.0-46.5 months) and mean age was 44 years (13-80 years). The VAS and AOFAS scores were significantly improved at the final follow-up (7.0 to 2.0, p<0.001, 78.0 to 92.0, p<0.001). Significant corrections in the HVA, IMA and DMAA were obtained(p<0.001). Eleven (9.0%, 11/122) cases recurred hallux valgus deformity. Postoperative IMA, DMAA and HVA showed significant moderate to strong correlation with HVA at final follow-up (rho: Spearman correlation coefficient, 0.42, 0.71, 0.87, p<0.001). There was no recurrence in cases of postoperative DMAA less than 11.3 degree (fisher exact test, p<0.001). Conclusion: High DMAA is one of numerous risk factor for hallux valgus recurrence after scarf and akin osteotomy. To avoid recurrence, we suggest that surgical correctional goal of DMAA should be considered less than 11.3 degrees.

Hallux Valgus Deformity

Background: Lateral displacement of the sesamoids of the first toe relative to the metatarsal head is a common finding in hallux valgus deformity. Several methods have been described for quantifying the amount of subluxation from anteroposterior radiographs but a tangential sesamoid radiograph has been determined to be the best view to evaluate sesamoid displacement. Method: We evaluated the sesamoid position at different angles of the first metatarsophalangeal (MTP) joint to determine the effect of first MTP joint dorsiflexion on sesamoid position when tangential sesamoid view radiographs are made. Sesamoid positions of 22 feet with hallux valgus were graded from the short axis computed tomography (CT) images obtained with the MTP joint in 0, 35, and 70 degrees of dorsiflexion. Results: Approximation of the sesamoids to reduction was apparent as dorsiflexion of the first MTP joint increased. Conclusion: Different dorsiflexion degrees of the first MTP joint when tangential sesamoid radiographs are made modulate the position of the sesamoids and may lead to misclassification on grading.

Category: Midfoot/Forefoot Introduction/Purpose: This study aimed to investigate the pedobarographic characteristics of tarsometatarsal instability and to identify factors associated with pedobarographic first tarsometatarsal instability in patients with hallux valgus deformity. Methods: Fifty-seven patients (mean age, 59.7 years; standard deviation, 11.4 years; 6 men and 51 women) with a hallux valgus angle (HVA) greater than 15° were included. All patients underwent a pedobarographic examination along with weight-bearing anteroposterior (AP) and lateral foot radiography. Radiographic measurements were compared between the two groups with and without pedobarographic first tarsometatarsal instability. The association between the radiographic and pedobarographic parameters of the first tarsometatarsal instability was analyzed using the chi-square test. Binary logistic regression analysis was performed to identify significant factors affecting pedobarographic first tarsometatarsal instability. Results: HVA (p<0.001), the intermetatarsal angle (p=0.001), and AP talo-first metatarsal angle were significantly different between the pedobarographically stable and unstable tarsometatarsal groups. There was no significant association between radiographic and pedobarographic instabilities of the first tarsometatarsal joint (p=0.924). HVA was found to be the only significant factor affecting pedobarographic tarsometatarsal joint instability (p=0.001). Conclusion: The pedobarographic examination has possible clinical utility in evaluating first tarsometatarsal joint instability in patients with hallux valgus deformity. Patients with greater HVA need to be carefully monitored for the presence of first tarsometatarsal instability, and the necessity of the Lapidus procedure should be considered.

Research background. The present final paper presents an analysis of the effects of physiotherapy on foot function when treating the hallux valgus deformity. The research object was the change of the deformity degree of the great toe, foot pain, muscle strength, load distribution in the sole, trajectory of the sole’s center of gravity and foot’s contact with the movement’s surface in different stages of walking after the treatment. Objectives of the research were to analyze scientific literature about the hallux valgus, the concept of foot function and its treatment; determine the changes in the deformity degree of the great toe, pain intensity and muscle strength prior to and after the physical therapy exercises; assess the load distribution in the soles of the respondents, trajectory of the sole’s center of gravity and foot’s contact with the movement’s surface in different stages of walking prior to and after the physiotherapy exercises. Methods. The study was carried out at the Out-Patient Recuperation Center of the Public Institution Šiauliai National Hospital. The computer-aided pedobarographic assessment of the foot was performed by a representative of the Bauerfeind Company at the Manual Medicine Clinic. The study was carried out from December 2013 to April 2014. Twelve respondents afflicted with hallux valgus deformity participated in the study. The duration of the exercise sessions was 11 Results. According to the analysis of the research data, the intensity of pain was influenced by both the exercises and the use of orthopedic supports. However, the pain decreased more after physiotherapy compared to the use of orthopedic supports. The changes in the deformity degree of the great toe and muscle strength were also positively affected by exercises. In EKt group the muscle strength of the tested muscles changed by 1–2 points. In the EO group the muscle strength and the deformity degree of the great toe remained unchanged after the use of orthopedic supports. Following the analysis of the load distribution in the sole, trajectory of the sole’s center of gravity and foot’s contact with the movement’s surface, it became obvious that the physiotherapy had positive a impact on the decrease of load distribution points in different places of the sole and the trajectory of the sole’s center of gravity for the respondents in the Conclusion. After the exercises the toe of one patient was aligned properly and the remaining patients were close to achieving proper alignment. Also, the exercises had a positive influence on the foot’s contact with the movement’s surface. The EO group did not observe any positive changes after using the orthopedic supports, i.e. the load distribution points, trajectory of the center of gravity and foot’s contact with the movement’s surface were not altered.Keywords: hallux valgus, foot function, physical therapy.

Hallux valgus deformity is a complex chronic progressive disease primarily characterized by a lateral great toe deviation and deformity of the first metatarsophalageal joint. Numerous etiological factors are related with the expression of this disease, and they are divided into two categories: endogenous and exogenous. Complexity of the hallux valgus deformity is reflected with the progression of the disease that gives rise to numerous forefoot deformities. The diagnosis is first of all affirmed by clinical examination and x-ray of the feet in a standing position. Treatment could be either operative or conservative. Conservative treatment has shown to be totally unsuccessful. Before decision making on the type of operative treatment, the patient?s complaints, age, profession, clinical and x-ray findings must be taken into consideration. Until now, over two hundred different operative procedures have been described, which clearly supports the observation that there is no single method which could resolve all clinical varieties of this deformity. Therefore, today, when making a choice on the surgical procedure of hallux valgus deformity, the utilization of surgical algorithm is recommended.

Severe Hallux Valgus

Category: Bunion Introduction/Purpose: First metatarsophalangeal (MTP) joint arthrodesis is widely accepted as a treatment option for severe hallux valgus deformities. Although successful results of first MTP joint arthrodesis for hallux valgus have been reported in previous studies, the reported rates of fusion have been lower than for the general hallux rigidus population. The purpose of this study was to demonstrate the failure rate of first MTP joint arthrodesis for severe hallux valgus deformities and to evaluate radiographic correction of hallux valgus parameters after the surgery. Methods: From January 2014 to June 2017, 34 patients underwent first MTP joint arthrodesis surgery for severe hallux valgus deformity and were included in this retrospective study. Severe hallux valgus was defined as having a hallux valgus angle (HVA) of greater than 40 degrees and an intermetatarsal angle (IMA) greater than 15 degrees. For radiographic evaluation, the patients were evaluated by measuring the IMA and HVA in preoperative and postoperative weight-bearing AP foot x-rays. We defined failure after first MTP joint arthrodesis as non-union, incomplete union, or implant breakage or migration leading to a symptomatic recurrence of hallux valgus deformity. Results: The mean preoperative IMA and HVA were 16.7 ± 4.2 degrees (range 8.4 to 26.5) and 45.2 ± 8.6 degrees (range 28.7 to 71.1) respectively, and the postoperative IMA and HVA were 11.3 ± 3.8 degrees (range 4.1 to 20.4) and 20.9 ± 11.8 degrees (range 0.4 to 51.1) respectively. The postoperative IMA and HVA were significantly improved after surgery (< 0.001). Among the 34 patients in this study, a 14.7% failure rate was reported (n=5). For fusion procedures performed without lag screw fixation, there was a 12.6-fold increase in failure risk when we used the small dorsal locking plate compared with the medium dorsal locking plate (Odds ratio = 12.571). Conclusion: First MTP joint arthrodesis is an effective and reliable option for severe hallux valgus correction. However, for this challenging cohort, the 14.7% failure rate in this study is consistent with other studies in the literature. For severe hallux valgus deformities, selection of implant may play a more significant role. The use of longer plates to gain additional purchase in the diaphyseal bone, lag screw augmentation, and utilizing flat cuts instead of cup and cone reaming to realign the joint may help mitigate the increased stresses placed on the fixation constructs for MTP arthrodesis.
