Abstract
BACKGROUND With the advent of effective disease-modifying medications, the surgical treatment of forefoot deformities in patients with rheumatoid arthritis (RA) has evolved from joint-sacrificing to joint-preserving surgery. However, it is unclear whether joint-preserving surgery is effective for the full range of metatarsophalangeal joint involvement. Hence, this study investigated the postoperative outcomes of joint-preserving surgery for rheumatoid forefoot deformities with a wide range of joint destruction. METHODS This retrospective observational study included 68 feet from 68 patients with RA who underwent joint-preserving surgery for forefoot deformities between 2014 and 2020. The Larsen grade classification was used to assess the first metatarsophalangeal joint destruction and classify patients into 4 groups as follows: 0 and 1 (n = 14), 2 (n = 21), 3 (n = 19), and 4 and 5 (n = 14). The Self-Administered Foot and Ankle Evaluation Questionnaire (SAFE-Q) score, hallux valgus angle (HVA), and intermetatarsal angle (IMA) were determined before surgery and at the last follow-up visit. RESULTS The median observation duration was 40 (range, 24-78) months. SAFE-Q scores of all groups significantly improved in all subscales at the last observation, with no significant differences among the study groups. Radiographic evaluations of all groups revealed significant improvements in HVA and IMA after surgery, with no significant differences among the groups. CONCLUSION In patients using the surgical approaches described in this study, joint-preserving surgery for rheumatoid forefoot deformities led to satisfactory clinical and radiographic improvements, regardless of the severity of joint destruction.

Abstract
BACKGROUND The combination of distal osteotomy with lateral dissection in joint-preserving surgery for severe hallux valgus deformity has recently begun to yield encouraging results. We examined the frequency of complications and risk factors of those for joint-preserving surgery in patients with and without rheumatoid arthritis (RA). METHODS A retrospective, observational study of 72 feet (27 patients with RA) was performed. The inclusion criteria were patients who underwent joint-preserving surgery for hallux valgus deformity at our hospital between January 2008 and March 2016 who could be followed up with for longer than 12 months. RESULTS The mean preoperative and immediate postoperative hallux valgus angles (HVA) were 41.8 and 4.4, respectively. The mean preoperative and immediate postoperative intermetatarsal angles between the first and second metatarsal bones (M1-M2A) were 14.6 and 5.8, respectively. At the final postoperative evaluation, the mean HVA was 8.8 and the mean M1-M2A was 6.4.Data were compared among the patients with complications (recurrent valgus deformity, varus deformity), and those without complications (normal HVA) at the final postoperative evaluation. The rate of RA in the varus deformity group was 71.4%, which tended to be higher than in other groups (p = .058). The mean preoperative HVA were 48.2 and 52.6 in the group of recurrent valgus deformity and varus deformity, which was higher than the normal HVA group (p = .001). CONCLUSIONS High preoperative HVA was a risk factor for the recurrence of valgus deformity. Most of the varus deformities were observed in the RA group with high preoperative HVA; therefore, caution should be exercised in operating on patients with severe deformity or those with RA.

Radiographic factors associated with painful callosities after forefoot surgery in patients with rheumatoid arthritis. Mod Rheumatol 2023; 33:104-110. [PMID: 34939107 DOI: 10.1093/mr/roab131] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 12/03/2021] [Accepted: 12/21/2021] [Indexed: 01/05/2023]
Abstract
OBJECTIVES Operative procedures for rheumatoid forefoot deformities have gradually changed from arthrodesis or resection arthroplasty to joint-preserving surgery. Although joint-preserving arthroplasty has yielded good outcomes, painful plantar callosities may occur post-operatively. This study aimed to reveal the radiographic factors associated with painful callosities after joint-preserving surgery for forefoot deformities in patients with rheumatoid arthritis (RA). METHODS We retrospectively evaluated 166 feet in 133 patients with RA who underwent forefoot joint-preserving arthroplasty, including proximal rotational closing-wedge osteotomies of the first metatarsal, between January 2012 and December 2015. Logistic regression analysis was performed with the objective variable set as the presence/absence of painful plantar callosities at the final observation and the explanatory variables set as several radiographic factors, including post-operative relative first metatarsal length (RML), amount of dorsal dislocation of the fifth metatarsal (5DD), and arc failure of the lesser toes. RESULTS At the final follow-up, 42 of the 166 feet (25.3%) had painful callosities under the metatarsal heads post-operatively. Logistic regression analysis showed that the RML, 5DD, and lesser toes' arc failure were significantly associated with painful callosities. CONCLUSIONS We identified that RML, 5DD, and arc failure of the lesser toes were associated with painful plantar callosities after the surgery.

Abstract
BACKGROUND Patients who have noninflammatory arthritis of the feet may develop destructive changes on the first metatarsal head and painful dislocation of the metatarsophalangeal (MTP) joint of 1 or more lesser toes. This aim of this study was to compare feet with noninflammatory arthritis and those with rheumatoid arthritis (RA) with respect to the clinical and radiographic outcomes after treatment of these destructive deformities with a modified Scarf osteotomy with medial capsular interposition into the newly formed first MTP joint, combined with metatarsal shortening offset osteotomy. METHODS A retrospective observational study of 93 feet (31 with noninflammatory arthritis and 62 with RA) was performed. Hallux and lesser-toe scores on the Japanese Society for Surgery of the Foot (JSSF) scoring system, a self-administered foot evaluation questionnaire (SAFE-Q), and preoperative and postoperative radiographic parameters were evaluated. RESULTS There were significant improvements at the time of the final follow-up in the mean scores on the hallux and lesser-toe scales of the JSSF system and in the SAFE-Q score. The postoperative JSSF lesser-toes function score was better for the feet with noninflammatory arthritis feet than the feet with RA. There was no significant difference in the hallux valgus angle (HVA) between 1 month postoperatively and the final follow-up for both groups. Furthermore, the HVA showed a strong correlation between the 1-month and final follow-up values. CONCLUSIONS The combination of the modified Scarf osteotomy with medial capsular interposition and shortening metatarsal offset osteotomy was useful and safe in feet with noninflammatory arthritis. The HVA at 1 month after surgery is useful to predict the HVA within 5 years after surgery. The postoperative clinical score for the lesser toes was better in the feet with noninflammatory arthritis.

Abstract
ZusammenfassungDer Unterschied zwischen rheumatischen und degenerativen Veränderungen am
Fuß liegt in der fortschreitenden Destruktion der Gelenke bei
persistierender Synovialitis der rheumatoiden Arthritis (RA). Unter der heute
wirksameren immunsuppressiven Therapie und eines frühen und aggressiven
Beginns zeigen sich mildere Verlaufsformen. So können zunehmend auch
gelenkerhaltende Verfahren der Vorfußchirurgie Anwendung finden.
Entscheidend ist hier jedoch die Remission mit sicherer Krankheitskontrolle
für den gelenkerhaltenden Eingriff. Dennoch ist das Rezidiv- und
Fehlstellungsrisiko aufgrund wiederkehrender arthritischer Phasen höher.
Rheumaorthopädische Standardverfahren, wie die Arthrodese des
Großzehengrundgelenkes mit Resektion der Metatarsaleköpfchen
haben aber Ihren Stellenwert beim Vollbild des erosiven rheumatischen
Vorfußes nicht verloren. Ein standardisiertes Vorgehen fehlt. Umso
wichtiger ist es, mit jedem Patienten individuell die richtigen
Maßnahmen zu festzulegen.

Abstract
Background: Increasing of intermetatarsal angle between the first and second metatarsals (M1-M2A) has been reported as a risk factor for recurrence of hallux valgus (HV) deformity, on the other hand, increasing of intermetatarsal angle between the second and fifth metatarsals (M2-M5A) has been reported as a risk factor for resubluxation of the metatarsophalangeal (MTP) joint of the lesser toe after rheumatoid forefoot surgery. In this study, parameters related to increasing M2-M5A were investigated, as compared with M1-M2A and M1-M5A. Methods: Radiographic parameters including M1-M2A, M1-M5A, and M2-M5A were retrospectively evaluated for 119 lower limbs from 68 patients with rheumatoid arthritis (RA). To clarify the clinical importance of these intermetatarsal angles, relationships with results from the timed up-and-go (TUG) test were also investigated. Results: M1-M5A showed no correlation with mid-hind foot parameters, whereas M1-M2A and M2-M5A correlated with valgus/varus parameters. An increased M1-M2A was associated with lateral shift of the loading axis in the tibial plafond, whereas an increased M2-M5A was associated with medial shift, but M1-M5A showed no associations. M2-M5A/M1-M2A was significantly lower (1.7) in the normal TUG group than in the delayed TUG group (2.8) (p=0.045). Conclusions: Different patterns of spread are seen for the forefoot. One has a predominantly increased M1-M2A with lateral shift of the loading point in the tibial plafond, whereas the other has a predominantly increased M2-M5A with medial shift of the loading point in the tibial plafond. M2-M5A also should be calculated, and M2-M5A/M1-M2A might be meaningful in understanding physical mobility in RA patients.

More than 20 years' follow-up of metatarsal neck shortening oblique osteotomy for rheumatoid forefoot deformity. J Orthop Sci 2022; 28:607-613. [PMID: 35396140 DOI: 10.1016/j.jos.2022.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 02/05/2022] [Accepted: 03/03/2022] [Indexed: 02/09/2023]
Abstract
BACKGROUND In recent years, advances in pharmacotherapy for rheumatoid arthritis (RA) have dramatically improved the control of disease activity. However, a significant number of patients still develop forefoot deformity. The purpose of this study was to investigate the results of more than 20 years' follow-up of metatarsal neck shortening oblique osteotomy (SOO) for forefoot deformity in patients with RA. METHODS The metatarsal neck SOO was performed on 163 feet in 108 patients between January 1985 and December 1996 in the authors' hospital. For the patients, who met the survey criteria, an observational study was performed clinically and radiologically at the baseline and at more than 20 years after surgery. RESULTS A retrospective cohort study was conducted on 36 feet in 22 patients, all of whom were female, and the mean age at surgery was 45.6 (35.0-63.0) years old. The follow-up period was 25.1 (21.0-31.0) years. The presence of painful callosities in the surgically treated feet without revised surgeries decreased from 32 feet (100%) to 4 feet (12.5%) at the last follow-up with mild pain that did not cause any footwear problems. Re-osteotomy at the metatarsal of the lessor toe was performed on four feet in two patients. Radiologically, among 128 toes without revised surgeries, 85% were able to have the joint space preserved, and 89% maintained a pain-free condition without any recurrence of deformity. The mean total Japanese Society for Surgery for the Foot (JSSF) RA foot and ankle score was 64.0/100, and the visual analogue scale (VAS) of overall satisfaction was 62 (0: dissatisfied, 100: highly satisfied). The overall satisfaction had a positive correlation with calcaneal pitch and negative correlation with joint space narrowing at the talocrural joint. CONCLUSIONS Metatarsal neck SOO appeared to be effective for patients with RA. The deformity was corrected and retained for a long time.

Abstract
We investigated the clinical outcomes of surgical procedures for the treatment of forefoot deformities in patients with rheumatoid arthritis. Twenty feet in 16 women (mean age 62.1 years) underwent corrective osteotomy of the first metatarsal bone with shortening oblique osteotomy of the lesser metatarsophalangeal joints (joint-preservation group), while 13 feet in 12 women (mean age 67.4 years) underwent arthrodesis of the first metatarsophalangeal joint with resection arthroplasty of the lesser metatarsophalangeal joints (joint-sacrifice group); mean follow-up for each group was 25.8 and 23.8 months, respectively. The mean total Japanese Society for Surgery of the Foot (JSSF) scale improved significantly from 64.2 to 89.2 in the joint-preservation group (p < .001), and from 54.2 to 74.2 in the joint-sacrifice group (p = .003). In the joint-preservation group, the postoperative range of motion (ROM) of the joint, walking ability, and activities of daily living scores of the JSSF scale were significantly higher than those in the joint-sacrifice group (p = .001, p = .001, and p = .019, respectively). There were no differences in the subscale scores of the self-administered foot evaluation questionnaire between 2 groups either pre- or postoperatively. No differences in the postoperative complications were found between 2 groups. Although the joint-sacrificing procedure resulted in lower objective outcomes than the joint-preserving procedure regarding the ROM of the joint, the walking ability, and the level of activities of daily living, both procedures resulted in similar treatment outcomes when evaluated by the subjective measures.

Forefoot Deformities in Patients with Rheumatoid Arthritis: Mid- to Long-Term Result of Joint-Preserving Surgery in Comparison with Resection Arthroplasty. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182111257. [PMID: 34769775 PMCID: PMC8583379 DOI: 10.3390/ijerph182111257] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 10/22/2021] [Accepted: 10/23/2021] [Indexed: 11/30/2022]
Abstract
Background: Joint-preserving surgery for the forefoot has been increasingly performed for rheumatoid arthritis (RA). We compared joint-preserving surgeries with resection arthroplasty for RA in the forefoot. Methods: Forefoot surgeries were performed on 62 toes in 42 patients with RA (men: 2; women: 40) between 2002 and 2018. Three groups were compared: PP—31 toes treated with joint-preserving surgery involving the modified Mann method for the big toe and offset osteotomy for lesser toes, PR—15 toes treated with joint-preserving surgery for the big toe and resection arthroplasty for lesser toes, and RR—16 toes treated with resection arthroplasty for all the toes. Results: The PP group had significantly higher mean scores on a scale for RA in the foot and ankle at the latest follow-up than the RR group (86 vs. 75 points; p < 0.05). Hallux valgus (angle > 20°) of the big toe at the latest follow-up recurred in 10 (32%), 9 (60%), and 16 (100%) patients in the PP, PR, and RR groups, respectively. A revision surgery was performed in one patient each in the PP and PR groups. Conclusions: Joint-preserving surgery is superior to resection arthroplasty in preventing function loss and the recurrence of hallux valgus.

Combination of Modified Scarf Osteotomy and Metatarsal Shortening Offset Osteotomy for Rheumatoid Forefoot Deformity. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph181910473. [PMID: 34639772 PMCID: PMC8508223 DOI: 10.3390/ijerph181910473] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 09/27/2021] [Accepted: 10/02/2021] [Indexed: 11/17/2022]
Abstract
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.

Association of Decreased Physical Activity with Rheumatoid Mid-Hindfoot Deformity/Destruction. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph181910037.

Abstract
Foot/ankle problems remain important issues in rheumatoid arthritis (RA) patients. Although forefoot deformity generally takes a major place in surgical treatment, concomitant mid-hindfoot deformity is also commonly seen. In this situation, it can be easy to overlook that mid-hindfoot deformity can also induce or exacerbate clinical problems behind the forefoot events. Thus, the relationship between mid-hindfoot deformity/destruction and physical activity/ADL was investigated. Radiographic findings of 101 lower limbs (59 patients) were retrospectively evaluated. Alignment parameters in the lower extremity and joint destruction grade (Larsen grade) were measured. The timed-up-and-go (TUG) test, modified health assessment questionnaire (mHAQ), pain, self-reported scores for the foot and ankle (SAFE-Q), and RA disease activity were investigated to assess clinical status. The relationships among these parameters were evaluated. Subtalar joint destruction was correlated with TUG time (r = 0.329), mHAQ score (r = 0.338), and SAFE-Q: social functioning (r = 0.332). TUG time was correlated with the HKA (r = −0.527), talo-1st metatarsal angle (r = 0.64), calcaneal pitch angle (r = −0.433), M1-M5A (r = −0.345), and M2-M5A (r = −0.475). On multivariable linear regression analysis, TUG time had a relatively strong correlation with the talo-1st metatarsal angle (β = 0.452), and was negatively correlated with calcaneal pitch angle (β = −0.326). Ankle joint destruction was also correlated with TUG time (β = 0.214). Development of structural problems or conditions in mid-hindfoot, especially flatfoot deformity, were related with decreased physical activity in RA patients. Wearing an insole (arch support) as a preventative measure and short foot exercise should be considered from the early phase of deformity/destruction in the mid-hindfoot in the management of RA.

Abstract
Dorsal dislocation of metatarsophalangeal (MTP) joints of the lesser toe frequently occurs in patients with rheumatoid arthritis (RA), and may cause painful and uncomfortable plantar callosities and ulceration. The current study examined the reliability and clinical relevance of a novel radiographic parameter (the MTP overlap distance [MOD]) in evaluating the severity of MTP joint dislocation. The subjects of the current study were 147 RA patients (276 feet; 1104 toes). MOD, defined as the overlap distance of the metatarsal head and the proximal end of the phalanx, was measured on plain radiographs. The relationship between the MOD and clinical complaints (forefoot pain and/or callosity formation) was analyzed to create a severity grading system. As a result, toes with callosities had a significantly larger MOD. ROC analysis revealed that the MOD had a high AUC for predicting an asymptomatic foot (−0.70) and callosities (0.89). MOD grades were defined as follows: grade 1, 0 ≤ MOD < 5 mm; grade 2, 5 ≤ MOD < 10 mm; and grade 3, MOD ≥ 10 mm. The intra- and inter-observer reliability of the MOD grade had high reproducibility. Furthermore, the MOD and MOD grade improved significantly after joint-preserving surgeries for lesser toe deformities. Our results suggest that MOD and MOD grade might be useful tools for the evaluation of deformities of the lesser toe and the effect of surgical intervention for MTP joints in patients with RA.

Abstract
The combination of first metatarsophalangeal joint arthrodesis and resection arthroplasty of all lesser metatarsal heads has been historically considered the golden standard treatment for rheumatoid forefoot deformities. However, as recent improved management of rheumatoid arthritis have reduced progression of joint destruction, the surgical treatments for rheumatoid forefoot deformities have gradually changed from joint-sacrificing surgery, such as arthrodesis and resection arthroplasty, to joint-preserving surgery. The aim of this literature review was to provide current evidence for joint-preserving surgery for rheumatoid forefoot deformities. We focused on the indications, specific outcomes, and postsurgical complications of joint-preserving surgery in this review.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is an autoimmune disorder and a chronic inflammatory disease that can damage joints throughout the body. As dramatic improvements in medical treatment have contributed to reduced progression of joint destruction, surgical methods for the treatment of RA-related forefoot deformities have gradually changed from joint-sacrificing to joint-preserving. The aim of this study was to assess the long-term outcomes, including patient-reported outcomes, of joint-preserving surgery for forefoot deformities associated with RA. METHODS This retrospective study included 105 feet in 89 patients with RA who were treated during the period of January 2012 to May 2015 and had a minimum of 5 years of follow-up (mean, 6.0 ± 0.9 years). The patient-reported outcome measure used was the Self-Administered Foot Evaluation Questionnaire (SAFE-Q), which was completed preoperatively and at the latest follow-up (n = 53 feet). The hallux valgus angle (HVA), the intermetatarsal angle (IMA), and the position of the medial sesamoid were measured preoperatively, at 3 months postoperatively, and at the latest follow-up. Cases of delayed wound-healing, hallux valgus recurrence, nonunion at the osteotomy sites, and reoperation were recorded. Kaplan-Meier survival curves were used to determine the estimated survivorship, with reoperation as the end point. RESULTS Scores of all 5 subscales of the SAFE-Q demonstrated significant improvement at the latest follow-up. The average HVA and IMA decreased significantly 3 months postoperatively, and these measurements remained significantly lower than the preoperative values (p < 0.01). The position of the medial sesamoid at the latest follow-up improved significantly (p < 0.01). Delayed wound-healing was found at the site of surgery in 21 (20.0%) of the 105 feet. Recurrence of hallux valgus was observed in 11 (10.5%) of the feet. There was no case of nonunion at any osteotomy site. Eleven (10.5%) of the feet required reoperation. The estimated survivorship of the studied joint-preserving surgery at 7 years, with reoperation as the end point, was 89.5%. CONCLUSIONS Satisfactory long-term patient-reported and radiographic outcomes after joint-preserving surgery for forefoot deformities associated with RA can be achieved.

Abstract
BACKGROUND This retrospective study aimed to describe the techniques and results of distal metatarsal segmental shortening (DMSS) for the treatment of chronic irreducible metatarsophalangeal (MTP) dislocation of lesser toes. METHODS We retrospectively reviewed patients who underwent DMSS for chronic dislocation of MTP joints of lesser toes between January 2010 and December 2017 with follow-up of at least 24 months. Demographic data, radiographic measurements, functional outcomes, and complications were analyzed. Furthermore, the results of patients with short segment of shortening (group I, <10 mm) were compared to those with long segment of shortening (group II, ≥10 mm). A total of 43 MTP joints of 30 patients with an average age of 70.4 years were included. RESULTS Union was observed in 42 metatarsals (97.7%). Mean American Orthopaedic Foot & Ankle Society scale scores improved significantly from 42.2 (range, 15-65) preoperatively to 79.1 (range, 52-90) (P < .001). Mean visual analog scale pain score improved significantly from 5.0 (range, 1-9) preoperatively to 1.8 (range, 0-6) (P < .001). Complications included 1 nonunion, 1 osteonecrosis, 3 metatarsal angulation, 4 recurrent instability, 4 symptomatic osteoarthritis, 3 transfer metatarsalgia, and 1 floating toe. Group I included 23 MTP joints and group II included 20 MTP joints. There was no significant difference in clinical outcomes and complications between the 2 groups. CONCLUSION DMSS was a reliable procedure for the treatment of chronic irreducible dislocated MTP joint of lesser toes. It provided satisfactory surgical outcomes and a low rate of postoperative complications, regardless of length of metatarsal shortening. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Treatment of an Intractable Forefoot Ulcer Using Realignment Osteotomy in a Patient with Rheumatoid Arthritis. Case Rep Orthop 2020; 2020:8817456. [PMID: 32802537 PMCID: PMC7403941 DOI: 10.1155/2020/8817456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 07/03/2020] [Accepted: 07/20/2020] [Indexed: 12/03/2022] Open
Abstract
Forefoot deformities are common among patients with rheumatoid arthritis (RA). Herein, we describe a case of intractable ulceration on the dorsomedial aspect of the right 5th digit, secondary to forefoot deformity, in a 76-year-old woman with a 35-year history of RA. The ulcer was due to a persistent subcutaneous infection. Although the infection was controllable with antibiotics, there was concern of relapse because of the abnormal pressure on the skin due to an overlap of the 4th and 5th digits. We proceeded with surgical correction of the forefoot alignment, including shortening oblique osteotomy of metatarsals 2 through 5, rather than amputation of the 5th digit. Following surgery, targeted antibiotic treatment was provided. The postoperative course was unremarkable, and the patient recovered weight-bearing function without recurrence of pain or ulceration. Forefoot realignment is a feasible option that should be considered for treating intractable foot pain and ulceration secondary to long-lasting RA.

Abstract
OBJECTIVES To validate and establish targets for the physician-based clinical scale for foot surgery in rheumatoid arthritis (RA) patients based on patient-reported outcomes from a multicenter prospective cohort. METHODS We collected data on demographics, values from the RA foot and ankle scale by the Japanese Society for Surgery of the Foot (JSSF-RA), and patient-reported outcomes (PROs) including the Health Assessment Questionnaire Disability Index (HAQ-DI) before (baseline) and 6 and 12 months after joint surgery. Target values for JSSF-RA were determined according to the lower limit of the 95% CI of JSSF-RA in patients with HAQ-DI ≤0.5 after adjusting for age and sex. We used multiple linear regression analysis to examine potential predictors of JSSF-RA target achievement at baseline. RESULTS Cross-sectional analysis was conducted on data from 417 cases. The JSSF-RA target for foot and ankle surgery was set at 74 according to the JSSF-RA value corresponding to HAQ-DI ≤0.5 (mean 77.6, 95% CI: 74.3-80.9). Longitudinal analysis of patients who underwent foot surgery (N = 59) determined target cut-off values of 1.188 and 65 for HAQ-DI and JSSF-RA at baseline, respectively, as being predictive for achieving JSSF-RA ≥74 after surgery. CONCLUSIONS A JSSF-RA value of 74 represents an important target for patients with RA who have undergone foot surgery. In order to achieve this target, the timing of the surgery should be considered in the treatment of established RA patients.

Abstract
The aim was to identify effective surgical treatments for patients with rheumatoid arthritis in the foot and/or ankle. A systematic review of the literature was conducted via a data search of the PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and PROSPERO databases, from their inception until June 2019. Only non-randomized controlled trials and cohort studies were included in this review. Two of the present authors independently assessed the quality of each study and extracted the relevant data. A quality assessment of all articles was performed using the methodological index for non-randomized studies criteria. In addition, the Newcastle Ottawa scale was used for cohort studies. Thirteen studies met the inclusion criteria (five cohort studies and eight NRCTs). The total population considered was 923 patients (570 patients had RA), with a mean age of 58.8 years. Regarding the risk of bias, both the NRCTs and the cohort studies had a moderate level of quality. Despite the relatively low quality of these studies, surgical treatment for the foot and/or ankle is shown to reduce pain and improve functionality in patients with RA, in the short term (6–12 months).

Abstract
BACKGROUND Rheumatoid arthritis (RA) can cause significant forefoot disorders. If forefoot deformity and pain are severe, surgical treatment can be considered. The aim of this study was to analyze the long-term outcomes of surgical forefoot correction per Tillmann, which involves resection of the metatarsal heads through a transverse plantar approach for the lesser toes and a dorsomedial approach to the great toe. METHODS This retrospective study used patient-based questionnaires to analyze the revision rate, pain, use of orthoses, walking ability, forefoot function, and patient satisfaction of patients with RA who had undergone a complete forefoot correction of metatarsophalangeal (MTP) I to V. The study only included participants with RA before the era of biological agents and who were at least 20 years postoperatively. A total of 60 patients who had undergone 100 complete forefoot operations according to Tillmann 24.6 ± 3.5 years ago were included in this study. RESULTS The data collected showed that 35 reoperations were performed on 26 of the patients. Deformity relapses were often documented for the hallux valgus. More than 60% of the patients were able to wear conventional shoes. The distances the participants were able to walk were significantly increased by wearing shoes when compared with walking barefoot (P < .01). CONCLUSION While forefoot function remained difficult to assess, the majority of patients were able to use conventional shoes. This long-term follow-up study of patient-reported questionnaires completed more than 20 years after the Tillmann procedure showed that more than 80% of the patients remained satisfied with the outcome.

Abstract
Objectives: There have been few reports on factors affecting bone union after metatarsal osteotomies. The purpose of this study was to clarify the factors affecting bone union after distal shortening oblique osteotomy of the lesser metatarsals.Methods: Patients who underwent distal shortening oblique osteotomy of the lesser metatarsals were retrospectively investigated. Failure to achieve bone union at 6 months after surgery was defined as delayed union. Background characteristics and radiographic measurements were compared between patients with and those without delayed union, and factors affecting bone union were assessed using multivariate analysis.Results: Among 204 toes in 58 patients evaluated in this study, delayed union occurred in 28%. In multivariate analysis, corticosteroid use (odds ratio (OR), 3.68; 95% confidence interval (CI), 1.65-8.16; p< .01), larger preoperative overlap between the metatarsal and the proximal phalanx (OR, 1.11 (per 1 mm increase); 95% CI, 1.02-1.21; p= .02), and larger gap at the osteotomy site (OR, 3.02 (per 1 mm increase); 95% CI, 1.76-5.16; p< .01) were identified as independent risk factors of delayed union.Conclusion: The identified risk factors of delayed union after distal shortening metatarsal osteotomies were corticosteroid use, preoperative overlap between the metatarsal and the proximal phalanx, and a gap at the osteotomy site.

Abstract
Objectives: Joint-preserving rheumatoid forefoot surgery improves clinical outcomes, but postoperative range of motion (ROM) of the metatarsophalangeal (MTP) joint remains an issue. The objective of this study was to evaluate the effect of ROM exercise from the early period after lesser toe MTP joint-preserving surgery.Methods: A retrospective, observational study of 22 rheumatoid arthritis patients who underwent modified metatarsal shortening offset osteotomy was completed. Lesser toe scales were administered using the Japanese Society for Surgery of the Foot (JSSF) standard rating system, and the maximum distance of continuous walking was checked to evaluate clinical outcomes. Maximum passive ROM of the lesser toe MTP joints and the extension angle of the 2nd MTP joint at the terminal stance phase during gait were measured and evaluated.Results: Pain scores and ROM-related indices of the JSSF lesser toe scale improved significantly in the exercise group. The extension angle of the 2nd MTP joint at the terminal stance phase during gait was increased, and the maximum distance of continuous walking seemed longer.Conclusion: Passive/active ROM exercise from 2-weeks after surgery can improve a patient's activity and forefoot function through increasing ROM of the MTP joint at the terminal stance phase.

Abstract
Objectives: To clarify the effect of combining medial capsule interposition with modified scarf osteotomy for hallux valgus.Methods: A multicenter, retrospective study included 64 cases [59 osteoarthritis patients (excluding rheumatoid arthritis); age 68.8 years, range 40-93 years] of modified scarf osteotomy which were performed from 2013 to 2017 and followed for 26.6 (range, 13-50) months. Patients were treated by either (1) without medial capsule interposition (33 cases) or (2) combined with interposition (31 cases) at each senior surgeon's discretion. The Japanese Society for Surgery of the Foot (JSSF) hallux metatarsophalangeal (MTP)-interphalangeal scale was evaluated along with radiographic parameters (hallux valgus angle [HVA], first and second metatarsals intermetatarsal angles, and Hardy grade).Results: All JSSF scale and radiographic parameters were similar at baseline and significantly improved at final follow-up in both groups (pre-operation vs. final follow-up: p < .001). However, compared to without interposition group, interposition group showed significantly higher improvement in the JSSF scale (pre-operation to final follow-up: p value between the two groups at final follow-up) for pain (without interposition: 19.4-34.2, interposition: 18.4-37.1; p = .02), function (without interposition: 20.8-33.6, interposition: 18.3-36.6; p = .005), total score (without interposition: 41.5-81.8, interposition: 38.5-88.5; p < .001), and the MTP joint space (without interposition: 1.4-1.5 mm, interposition: 1.6-2.6 mm; p < .001) with significant correlation between the total JSSF score (r = .40; p = .001).Conclusion: Combining medial capsule interposition with modified scarf osteotomy significantly improved mid-term clinical outcomes.

Abstract
Introduction Modified Scarf osteotomy combined with metatarsal shortening offset osteotomy of the lesser toes provides stable forefoot realignment with preservation of the motion of the first metatarsophalangeal (MTP) joint. Indications & Contraindications Step 1: Preoperative Planning On a standing anteroposterior radiograph, plan the resection of the first metatarsal as the amount equal to the overlap of the first metatarsal and the base of the proximal phalanx, and plan to resect enough length of the lesser metatarsals to allow reduction of the MTP joints while keeping these metatarsals longer than the first. Step 2: Operating Room Setup (Fig.2) With the patient supine, and a fluoroscope in place to later check alignment and correction, ensure that full knee joint flexion is possible so that the foot can be placed parallel to the operating table. Step 3: Incisions (Fig. 3) Make the incisions. Step 4: Approach Approach the lesser toes through the lateral 2 dorsal toe incisions and the great toe through the dorsal first web space incision. Step 5: Osteotomy and Reduction Resect a sufficient amount of each lesser metatarsal neck to allow reduction of the respective MTP joint (Fig. 5-A); to correct the hallux valgus deformity, perform sufficient shortening and translation of the first metatarsal shaft through a horizontal longitudinal osteotomy (Fig. 5-B). Step 6: Fixation Lock the distal fragment (metatarsal head) of the lesser metatarsals into 3-mm-deep grooves in the cortical bone of the proximal fragment and then secure it to the proximal fragment with a 1.2-mm Kirschner wire (Fig. 6-A); shift the distal bone fragment of the first metatarsal laterally and securely fix it with screws (Fig. 6-B). Step 7: Medial Capsular Interposition and Closure After correction of the hallux valgus deformity using the modified Scarf osteotomy, interpose the 10-mm-wide capsular flap into the first MTP joint (Fig. 7). Results In our series of 76 cases in 60 patients, sufficient reduction of the hallux valgus deformity was achieved consistently even in cases with severe destruction (Larsen grade 4 or 5) of the first MTP joint due to rheumatoid arthritis2. Pitfalls & Challenges Background: Arthrodesis of the first metatarsophalangeal (MTP) joint has been recommended for severe hallux valgus deformity in patients with rheumatoid arthritis. We developed an alternative procedure that preserves motion of the first MTP joint while restoring alignment and balance to the forefoot. This procedure was shown to be effective in a series of 60 patients with a 3-year follow-up. Description: We perform a modified Scarf osteotomy, with the longitudinal first metatarsal cut parallel to the sole of the foot and with shortening of the metatarsal to realign the first ray. This is combined with an interpositional capsular arthroplasty of the first MTP joint and shortening offset osteotomies of the lesser metatarsals. Alternatives: Alternatives include arthrodesis of the first MTP joint combined with resection arthroplasty of the lesser MTP joints, or of all 5 MTP joints, or perhaps interpositional (total) joint arthroplasty for severe rheumatoid forefoot deformity/destruction. Rationale: The purpose of the modified Scarf osteotomy is preservation of motion of the first MTP joint and protection against destruction of the rheumatoid joint. The metatarsal shortening offset osteotomy provides rigid stabilization at the site of osteotomy after dynamic correction to make the transverse arch.

Abstract
BACKGROUND Arthrodesis of the first metatarsophalangeal (MTP) joint has been recommended for severe hallux valgus deformity in patients with rheumatoid arthritis (RA). However, with the progress of medical treatment of RA, joint preservation surgery has recently been performed. The aim of this study was to investigate the clinical and radiographic outcomes of modified Scarf osteotomy with medial capsule interposition for RA cases including severe destruction of the first MTP joint and to evaluate risk factors for recurrence. METHODS A retrospective observational study of 76 cases (60 patients) followed for a mean of 35.3 months (range, 24 to 56 months) after a modified Scarf osteotomy was performed. Scores on the Japanese Society for Surgery of the Foot (JSSF) RA foot and ankle scale, the JSSF hallux scale, and a self-administered foot evaluation questionnaire (SAFE-Q) were determined along with preoperative and postoperative radiographic parameters. RESULTS There was a significant improvement, from preoperatively to final follow-up, in the mean JSSF RA foot and ankle score (from 52.2 to 76.9 points) and the mean JSSF hallux score (from 38.2 to 74.5 points). There was a recurrence (hallux valgus angle [HVA] of >20°) in 12 feet (16%). The preoperative DAS28-CRP score (disease activity score [based on 28 joints in the body]-C-reactive protein score) and intermetatarsal angles between the first and second metatarsals (M1M2A) and between the first and fifth metatarsals (M1M5A) were significantly greater in the recurrence group, as were the HVA, M1M2A, M1M5A, and Hardy grade at 3 months after surgery. There was a significant negative correlation between the preoperative DAS28-CRP score and the JSSF RA foot and ankle score at final follow-up (β = -0.39, p = 0.02) and a significant positive correlation between the preoperative DAS28-CRP score and the HVA at final follow-up (β = 0.44, p = 0.001). CONCLUSIONS The modified Scarf osteotomy with medial capsule interposition for hallux valgus deformity improved clinical and radiographic outcomes in RA cases with severe destruction of the first MTP joint. Increased preoperative M1M2A and M1M5A; incomplete reduction of the sesamoid bone; and the HVA, M1M2A, and M1M5A at 3 months after surgery should be evaluated as they are associated with recurrence of the deformity. The preoperative DAS28-CRP score was associated with the clinical and radiographic outcomes after surgery. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
BACKGROUND We investigated the clinical outcomes of resection and joint-preserving arthroplasty for forefoot deformities in patients with rheumatoid arthritis. METHODS Sixteen feet of 14 women (average age, 67.1 years; range, 53-82) underwent resection arthroplasty of the metatarsal head (resection group), and 18 feet of 15 women (average age, 61.3 years; range, 40-73) underwent a metatarsophalangeal joint-preserving procedure with shortening oblique metatarsal osteotomies of the lesser toes (joint preservation group). The mean disease duration in the resection and joint preservation groups was 23.6 and 19.1 years, and the average follow-up period was 37.3 and 33.5 months, respectively. The classification of Larsen was used to assess the severity of destruction of the metatarsophalangeal (MTP) joint. Preoperative and postoperative clinical evaluation included Japanese Society for Surgery of the Foot (JSSF) score and postoperative complications. RESULTS The number of preoperative radiographic destruction of the MTP joints (Larsen grade II, III, IV, and V) was 0, 29, 39, and 12 joints in the resection group and 13, 67, 9, and 1 joints in the joint preservation group. The mean JSSF score improved significantly from 61.3 to 83.9 points in the resection group ( P < .001) and from 62.2 to 90.8 points in the joint preservation group ( P < .001). In the resection group, recurrence of callosities and claw toe deformity was observed in 6 and 3 feet, respectively. In the joint-preserving group, recurrence of callosities and hammer toe deformity was observed in 1 foot each. CONCLUSION The resection arthroplasty and joint-preserving procedure showed satisfactory clinical outcomes. However, whether both procedures can maintain the good clinical results without the recurrence of forefoot deformity will require longer follow-up.

Abstract
Purpose The purpose of this retrospective study is to clarify the difference in plantar pressure distribution during walking and related patient-based outcomes between forefoot joint-preserving arthroplasty and resection-replacement arthroplasty in patients with rheumatoid arthritis (RA). Methods Four groups of patients were recruited. Group1 included 22 feet of 11 healthy controls (age 48.6 years), Group2 included 36 feet of 28 RA patients with deformed non-operated feet (age 64.8 years, Disease activity score assessing 28 joints with CRP [DAS28-CRP] 2.3), Group3 included 27 feet of 20 RA patients with metatarsal head resection-replacement arthroplasty (age 60.7 years, post-operative duration 5.6 years, DAS28-CRP 2.4), and Group4 included 34 feet of 29 RA patients with metatarsophalangeal (MTP) joint-preserving arthroplasty (age 64.6 years, post-operative duration 3.2 years, DAS28-CRP 2.3). Patients were cross-sectionally examined by F-SCAN II to evaluate walking plantar pressure, and the self-administered foot evaluation questionnaire (SAFE-Q). Twenty joint-preserving arthroplasty feet were longitudinally examined at both pre- and post-operation. Results In the 1st MTP joint, Group4 showed higher pressure distribution (13.7%) than Group2 (8.0%) and Group3 (6.7%) (P<0.001). In the 2nd-3rd MTP joint, Group4 showed lower pressure distribution (9.0%) than Group2 (14.5%) (P<0.001) and Group3 (11.5%) (P<0.05). On longitudinal analysis, Group4 showed increased 1st MTP joint pressure (8.5% vs. 14.7%; P<0.001) and decreased 2nd-3rd MTP joint pressure (15.2% vs. 10.7%; P<0.01) distribution. In the SAFE-Q subscale scores, Group4 showed higher scores than Group3 in pain and pain-related scores (84.1 vs. 71.7; P<0.01) and in shoe-related scores (62.5 vs. 43.1; P<0.01). Conclusions Joint-preserving arthroplasty resulted in higher 1st MTP joint and lower 2nd-3rd MTP joint pressures than resection-replacement arthroplasty, which were associated with better patient-based outcomes.
