Cross-cultural adaptation and validation of a Spanish version of the self-administered foot evaluation questionnaire (SAFE-Q)

BackgroundThe self-administered foot evaluation questionnaire is a comprehensive measure for assessing the perception of patients regarding their foot-related problems. However, it is currently only available in English and Japanesse. Therefore, this study aimed to cross-culturally adapt the questionnaire to Spanish and assess its psychometric properties. MethodsThe methodology recommended by the International Society for Pharmaco Economics and Outcomes Research for translating and validating patient-reported outcome measures was followed for the Spanish translation. After a pilot study with 10 patients and 10 controls, an observational study was carried out between March and December 2021. The Spanish version of the questionnaire was filled by 100 patients with unilateral foot disorders, and the time spent to complete each questionnaire was recorded. Cronbach's alpha was calculated to analyze the internal consistency of the scale and Pearson's correlation coefficients for the degree of inter-subscale associations. ResultsThe maximum correlation coefficient for the Physical Functioning, Daily Living, and Social Functioning subscales was 0.768. The inter-subscale correlation coefficients were significant (p < 0.001). Additionally, the value of Cronbach's alpha for the whole scale was 0.894 (95% confidence interval, 0.858–0.924). The values of Cronbach's alpha varied between 0.863 and 0.889 when the value of one of the five subscales was suppressed, which can be considered a measure of good internal consistency. ConclusionThe Spanish version of the questionnaire is valid and reliable. The method followed for its transcultural adaptation ensured its conceptual equivalence with the original questionnaire. Health practitioners can use the self-administered foot evaluation questionnaire as a complementary method to assess the interventions performed for ankle and foot disorders among native Spanish speakers; however, further research is necessary to assess its consistency for use by populations from other Spanish-speaking countries.

Quality of life in Werner syndrome and associated subjective foot/ankle symptoms: A cross-sectional survey.

The aims of this study were to assess the general quality of life and foot/ankle health-related quality of life among subjects with Werner syndrome (WS) and to determine subjective foot/ankle symptoms associated with quality of life. Using a questionnaire survey, patients were asked to provide information on age, sex and presence of subjective symptoms and complete both the 36-Item Short Form Health Survey (SF-36) questionnaire and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). Statistical analyses were performed using Student's t-test, the Mann-Whitney U test, Fisher's exact test and Spearman's rank correlation. Data from 12 patients with an average age of 54 ± 8.6 years were analyzed. The mean SF-36 score for the domain of physical functioning was 21.2; for role-physical function, 32.6; for bodily pain, 38.5; for general health, 34.4; for vitality, 44.8; for social function, 38.5; for role-emotional function and for mental health, 46.7. The mean mental component summary was as high as the national standard, but it was low in men. The mean SAFE-Q scores were also low. Patients with ulcers had significantly more pain and low general health perception. As compared with the national standard, the role/social component score was not low, and there was a correlation in most domains of the SAFE-Q. In WS, the general health-related quality of life was low overall in the physical domain and low only in men for the mental domain, whereas it was low in the social domain when foot/ankle health-related quality of life was low.

Early results of intramedullary nail fixation in distal tibia oblique osteotomy for the reduction of soft tissue complications.

During distal tibial oblique osteotomy, external fixators can increase pin site infection risk, whereas plates can cause wound necrosis, necessitating a compromise between soft-tissue position and length. We provide the first report of the early results of intramedullary nail fixation in these osteotomies for avoiding soft tissue complications. Ten ankles, classed as Takakura-Tanaka stages 3a to 4 and unclassified and treated via distal tibial oblique osteotomy for ankle osteoarthritis between 2017 and 2021, were included. Osteotomy was performed obliquely from the distal medial tibia to the tibiofibular joint. The distal tibial fragment was rotated distally in the coronal plane for realignment. An intramedullary nail fixation was applied for stabilization. The resulting gap was filled with iliac bone graft. Ankles were evaluated on the Japanese Society for Surgery of the Foot ankle-Hindfoot Scale and Self-Administered Foot Evaluation Questionnaire before surgery and at final follow-up. Radiographic assessments were performed. Bone union was achieved within 3 months in all patients. There were no cases of wound necrosis or correction loss postsurgery. Japanese Society scale scores significantly improved from 40.3 ± 15.9 to 87.5 ± 12.6 (P < 0.01). Mean self-evaluation scale scores (pain and pain-related, physical functioning and daily living, social functioning, general health and well-being) improved significantly. shoe-related scores did not change significantly but improved. There was no correction loss after surgery, with an average widening of 24.2 mm and opening angle of 22.6° at the osteotomy site. Our study showed that intramedullary nail for fixation of the osteotomy site in distal tibial oblique osteotomy effectively prevents soft tissues complications even in osteotomy sites with large openings.

Total Talar Replacement for Idiopathic Osteonecrosis of the Talus: Investigation of Clinical Outcomes, Pain, ADL, QOL

Treatment of osteonecrosis of the talus is challenging. Nonoperative management includes nonweightbearing treatment. Various types of hindfoot fusion procedures have been performed, but delayed union and shortening of the operated leg have reportedly occurred. In contrast, talar body prosthesis is a surgical procedure with potential that relieves pain, restores ankle joint function, and is not associated with leg-length discrepancy. The aim of this study was to investigate postoperative pain, clinical outcomes, activities of daily living (ADL), and quality of life (QOL) after total talar replacement in patients with osteonecrosis of the talus. Ten ankles in 10 patients with idiopathic osteonecrosis of the talus who were treated with a total talar replacement between 2007 and 2015 were included in the investigation. Scores according to the visual analog scale (VAS), Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale, Functional Independence Measure (FIM), and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were assessed. The VAS score significantly improved from a mean of 80 ± 8 points before surgery to 18 ± 22 points after surgery (P < .01). The JSSF ankle-hindfoot scale score significantly improved from a mean of 53 ± 12 points before surgery to 89 ± 7 points after surgery (P < .01). The FIM score significantly improved from a mean of 122 ± 1 points before surgery to 125 ± 1 points after surgery (P < .01). The mean postoperative SAFE-Q scores were as follows: 81 ± 10.3 points for pain, 78 ± 14.7 points for physical function, 90 ± 12.4 points for social function, and 83 ± 15.4 points for shoe-related. Total talar replacement is a useful treatment for patients with osteonecrosis of the talus. This replacement surgery preserves the function of the ankle and subtalar joints, and improves pain, ADL, and QOL. Level IV, case series.

Comparison of short-term outcomes after distal metatarsal telescoping osteotomy and scarf osteotomy for hallux valgus in patients with rheumatoid arthritis

PurposeTo compare the clinical and radiographic outcomes of distal metatarsal telescoping osteotomy (DMTO) and scarf osteotomy for hallux valgus (HV) in patients with rheumatoid arthritis (RA). MethodsOverall, 21 feet in 19 patients treated with DMTO and 26 feet in 26 patients treated with scarf osteotomy were retrospectively compared with significantly longer follow-up periods in the former procedure (51.0 months vs. 28.0 months, P < 0.0001). Radiographic measurements of HV-related parameters and the clinical outcomes which were compared using the American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal joint score (AOFAS score) were obtained preoperatively and at the latest follow-up. A postoperative comparison of the patient-reported outcome measures was performed using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). ResultsBoth the DMTO and scarf procedures improved the AOFAS score and HV-related parameters. The improvement in the AOFAS score and corrective amount of radiographic parameters showed no significant differences between the two groups. The pain and pain-related subscales of the SAFE-Q were significantly better in the DMTO group (86.7 vs. 70.0, P = 0.0009). The operative time for all toes was significantly shorter in the DMTO group (176.0 min vs. 210.0 min, P = 0.0002). No significant differences were observed in the incidence of post-operative complications. ConclusionBoth DMTO and scarf osteotomy demonstrated comparable outcomes for mild-to-severe HV deformities in patients with RA. The DMTO may be considered as an alternative surgical method for HV deformity in patients with RA with the advantages of being an easy technique and having a shorter operative time.

Anterior talofibular ligament remnant quality is important for achieving a stable ankle after arthroscopic lateral ankle ligament repair.

The relationship between ligament remnant quality and postoperative outcomes after arthroscopic lateral ankle ligament repair for chronic lateral ankle instability is controversial. This study aimed to determine whether the signal intensity of the anterior talofibular ligament on preoperative magnetic resonance imaging and ligament remnant quality identified on arthroscopy are associated with recurrent ankle instability after arthroscopic lateral ankle ligament repair. A total of 68 ankles from 67 patients with chronic lateral ankle instability who underwent arthroscopic lateral ankle ligament repair were retrospectively studied. The signal intensity of the anterior talofibular ligament was evaluated using T2-weighted magnetic resonance imaging. Arthroscopy was used to evaluate the thickness and mechanical resistance of the anterior talofibular ligament by hook palpation and to classify ankles into two groups: the present anterior talofibular ligament group with adequate mechanical resistance and the absent anterior talofibular ligament group with no mechanical resistance. The outcomes included recurrent ankle instability (respraining of the operated ankle after surgery) and Self-Administered Foot Evaluation Questionnaire scores. Thirteen ankles were diagnosed with recurrent ankle instability. Patients with a high anterior talofibular ligament T2 signal intensity experienced more recurrent ankle instability than those with a low intensity. As determined via arthroscopy, the absent anterior talofibular ligament group had a higher rate of recurrent ankle instability than the present anterior talofibular ligament group. There were no significant differences in Self-Administered Foot Evaluation Questionnaire scores between patients with high and low anterior talofibular ligament T2 signal intensity, as well as between absent and present anterior talofibular ligament groups based on arthroscopy. Poor quality of the anterior talofibular ligament remnant could result in recurrent ankle instability after arthroscopic lateral ankle ligament repair. Therefore, when treating chronic lateral ankle instability, surgeons should consider ligament quality. IV.

Short-Term Clinical Outcomes Following Total Ankle Arthroplasty Without Concomitant Osteotomy in Ankles with Severe Preoperative Varus Deformity: Comparison to Ankles with Preoperative Neutral Alignment.

It remains controversial whether satisfactory outcomes can be obtained following total ankle arthroplasty (TAA) without osteotomy in patients with severe varus ankle deformities. This study aimed to examine outcomes following TAA without concomitant osteotomies in patients with severe varus ankle alignment by comparing them with those in patients with neutral alignment. Fifty-one patients (53 ankles; mean age, 71.4 ± 5.6 years) who underwent TAA using the TNK ankle prosthesis were examined (mean follow-up, 36.8 ± 17.8 months). Patients were allocated into groups according to the preoperative talar tilt (TT) angle: the neutral group (preoperative TT angle <10°; n = 37) and the varus group (preoperative TT angle ≥10°; n = 16). Outcome measures, including the Japanese Society for Surgery of the Foot scale, Self-Administered Foot Evaluation Questionnaire, ankle range of motion, and radiographic parameters, were assessed before surgery and at the final follow-up. Significant improvements were observed in clinical and radiographic outcomes in both groups after surgery. Postoperative Japanese Society for Surgery of the Foot scale and subscale scores of pain and shoes in the Self-Administered Foot Evaluation Questionnaire were not significantly different between the groups, whereas subscale scores of function, social, and health were greater in the varus group than in the neutral group at the final follow-up. Radiographic parameters, including TT angle and tibial axis-medial malleolus (TMM) angle, improved postoperatively and were not significantly different between the neutral (mean TT angle, 0.5 ± 0.7°; mean TMM angle, 16.0 ± 4.6°) and varus (meanTT angle, 0.4 ± 0.7°; meanTMM angle, 17.0 ± 5.3°) groups at the final follow-up. To achieve neutral alignment, adjunctive procedures were required more often in the varus group. Outcomes of TAA using the TNK ankle prosthesis were favorable in patients with severe varus ankle and in those with neutral ankle without concomitant osteotomy. Satisfactory outcomes could be achieved in patients with severe varus ankle alignment after TAA without concomitant osteotomy.

Clinical Outcomes of Arthroscopic Ankle Lateral Ligament Repair with Accelerated Rehabilitation

Category: Arthroscopy; Ankle; Sports Introduction/Purpose: Although the minimal invasiveness of arthroscopic ankle lateral ligament repair (ALLR) means that an early return to sporting activities can be anticipated, many reports have described postoperative cast immobilization and the avoidance of weight-bearing for a certain period of time. Accelerated rehabilitation (AR), in which the period of immobilization is kept to a minimum and early weight-bearing exercises are actively introduced, may be helpful for an early return to sport. The purpose of this study was to investigate the therapeutic outcomes of ALLR with AR including the minimum duration of postoperative ankle immobilization and proactive early weight-bearing. Methods: A total of 23 ankles of 22 patients (11 men, 11 women; mean age 38.7 years) who underwent ALLR for chronic lateral ankle instability were investigated. Postoperative management included the avoidance of weight-bearing until postoperative day (POD) 3, after which full weight-bearing walking with a brace was permitted. The objective was to return to competitive sport 8 weeks after surgery. Preoperative and postoperative major symptoms, ankle range of motion (ROM), stress X-ray assessment, anterior translation (AT) measured with a capacitance-type strain sensor, the Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale, and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were evaluated. Results: Postoperatively, instability and pain resolved or improved in all patients. There was no significant postoperative change in ROM. There were significant improvements in the mean talar tilt angle (from 12° to 5.6°), in the mean anterior drawer distance (from 8.2 mm to 4.4 mm) on stress X-rays, and in the mean AT (from 10.5 mm to 4.6 mm). The JSSF scale improved significantly (from 68.8 to 96.8), and the SAFE-Q improved significantly on all subscales. Complete return to sport was achieved by 75% of the patients at 8 weeks after surgery. Conclusion: When AR with proactive weight-bearing exercises was implemented from POD 3 without ankle immobilization after ALLR, there were significant improvements in both objective assessments of ankle stability and clinical scores, and as many as 75% of the patients were able to make a complete return to sport within 8 weeks.

Effect of Accelerated Rehabilitation on Early Return to Sport After Arthroscopic Ankle Lateral Ligament Repair.

Background:Although the minimal invasiveness of arthroscopic ankle lateral ligament repair (ALLR) means that an early return to sporting activities can be anticipated, studies have described postoperative cast immobilization and the avoidance of weightbearing for a certain period. Accelerated rehabilitation may be helpful for an early return to sport.Purpose:To investigate clinical outcomes of ALLR and accelerated rehabilitation with a minimum duration of postoperative ankle immobilization and proactive early weightbearing.Study Design:Case series; Level of evidence, 4.Methods:This study investigated 23 ankles of 22 patients (11 men, 11 women; mean age, 38.7 years) who underwent ALLR for chronic lateral ankle instability. Postoperative management included the avoidance of weightbearing until postoperative day 3, after which full weightbearing walking with a brace was permitted. The objective was to return to competitive sport 8 weeks after surgery. The following were evaluated: pre- and postoperative instability and pain symptoms, ankle range of motion, anterior drawer distance on stress radiograph, anterior translation measured with a capacitance-type strain sensor, the Ankle-Hindfoot Scale from the Japanese Society for Surgery of the Foot, and the SAFE-Q (Self-Administered Foot Evaluation Questionnaire).Results:Two male patients dropped out and were excluded from analysis. Postoperatively, instability and pain resolved or improved in all patients. There was no significant postoperative change in range of motion. There were significant pre- to postoperative improvements in talar tilt angle (from 12.2°-5.6°, P < .01), anterior drawer distance (8.2-4.4 mm, P < .01), and anterior translation (10.5-4.6 mm, P < .01) as well as the Ankle-Hindfoot Scale score (68.8-96.8, P < .01) and all subscales of the SAFE-Q (P ≤ .01 for all). Complete return to sport was achieved by 75% of the patients at 8 weeks postoperatively.Conclusion:When accelerated rehabilitation with proactive weightbearing exercises was implemented from postoperative day 3 without ankle immobilization after ALLR, there were significant improvements in objective assessments of ankle stability and clinical scores, and as many as 75% of the patients were able to make a complete return to sport within 8 weeks.

Stepwise decision making for CFL repair in addition to arthroscopic ATFL repair yields good clinical outcomes in chronic lateral ankle instability regardless of the remnant quality

BackgroundAlthough arthroscopic anterior talofibular ligament (ATFL) repair for chronic lateral ankle instability (CLAI) has been widely performed, there are several issues such as the efficacy of the isolated ATFL repair for the ATFL and calcaneofibular ligament (CFL) injury and the influence of the poor remnant on the clinical outcomes to be discussed. This study aimed to evaluate clinical outcomes of the arthroscopic ATFL repair with the stepwise decision regarding the requirement of CFL repair and the influence of remnant qualities on clinical outcomes. MethodsForty-four ankles underwent arthroscopic surgery to repair the lateral ankle ligament for CLAI. After arthroscopic ATFL repair, CFL repair was performed if instability remained. Clinical outcomes including the Karlsson-Peterson (KP) scores, Japanese Society for Surgery of the Foot (JSSF) scale, and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were assessed at the final follow-up. ATFL remnants were classified into excellent, moderate, and poor according to the arthroscopic findings, and the clinical outcomes of each remnant group were compared. ResultsTwenty-five ankles were required for CFL repair after ATFL repair. K–P score was significantly improved from 66.1 ± 5.3 to 94.8 ± 6.5 points (p < 0.01). JSSF scale was significantly improved from 70.5 ± 4.5 to 95.9 ± 6.0 points (p < 0.01). The SAFE-Q was also significantly improved on all subscales. There were no significant differences in clinical outcomes among excellent, moderate, and poor remnants. ConclusionsStepwise decision for CFL repair in addition to arthroscopic ATFL repair gave satisfactory clinical outcomes in CLAI regardless of the remnant quality.

Patient-Reported Outcomes of Minimally Invasive Distal Linear Metatarsal Osteotomy for Hallux Valgus.

Modified Bösch osteotomy, or distal linear metatarsal osteotomy (DLMO), is one of the minimally invasive correctional operations for hallux valgus deformity. Although the clinical and radiographic results of DLMO have been previously shown, the relationship between clinical outcomes using a validated patient-reported outcome measure and radiographic corrections have yet to be evaluated. A total of 70 patients (97 feet) treated at our hospital were included in the study. The Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and radiographic data were evaluated at a minimum 1-year follow-up. Scores of all five SAFE-Q subscales showed a statistically significant improvement: pain and pain-related (from 63.3 to 86.6), physical functioning and daily living (from 81.3 to 92.7), social functioning (from 79.5 to 94.4), shoe-related (from 43.1 to 72.3), and general health and well-being (from 67.7 to 92.1). The mean hallux valgus angle improved from 39.1° to 9.3°, and the mean intermetatarsal angle improved from 16.6° to 7.0°. Recurrence and hallux varus at the final follow-up occurred in nine feet (9.3%) and 15 feet (15.5%), respectively. Four of the five SAFE-Q subscale scores improved significantly even in patients with hallux varus. Distal linear metatarsal osteotomy improves foot-related quality of life in patients with hallux valgus deformity despite of the high rate of postoperative radiographic complication, especially hallux varus. Patients might be willing to tolerate mild hallux varus after DLMO, as indicated by patient-centered clinical results.

Validity and reliability of the Persian version of self-administered foot evaluation questionnaire (SAFE-Q) in people with foot orthopedic problems

IntroductionFoot problems are one of the main causes of seeing a doctor. According to the World Health Organization's definition of health, the healthcare system must consider patients’ quality of life as an important entity. In this regard, many tools have been developed to evaluate patients' opinions about their health status. The purpose of the present study is to evaluate the validity and reliability of the Persian version of the Foot Self-Assessment Questionnaire (SAFE-Q) in patients with foot orthopedic problems. Method215 people aged 17–60 years with orthopedic foot problems were included in this cross-sectional study. The Spearman correlation coefficient of SAFE-Q questionnaires versus Foot Function Index (FFI) questionnaire was evaluated for the convergent validity. Forty-three people randomly completed SAFE-Q again one week later. Intraclass correlation coefficient (ICC) and Cronbach’s alpha was calculated to evaluate the test-retest reliability and internal consistency of the SAFE-Q, respectively. ResultsA strong relationship was found between the SAFE-Q total score and other scales with FFI questionnaire (r = 0.52 to 0.87). ICC test-retest reliability and Cronbach’s alpha were 0.981 and 0.98 for SAFE-Q, respectively. ConclusionThe results indicate that the Persian version of the SAFE-Q questionnaire has acceptable validity and reliability and can be used to assess the health status and quality of life of Persian speakers with orthopedic foot problems.

What is the best way for an inexperienced surgeon to learn total ankle arthroplasty?

BackgroundPrevious reports on the learning curve of total ankle arthroplasty (TAA) revealed that inexperienced surgeons should be more careful about operative indications and procedures during the learning curve period. Patients who underwent surgery with inexperienced surgeons may be associated with inferior clinical outcomes, such as frequent complications. This study aimed to evaluate the effect of the participation of experienced surgeons as assistants on the results of TAA performed by inexperienced surgeons. MethodsSurgeons whose experience in performing TAA included less than 15 ankles were defined as inexperienced surgeons; on the other hand, those whose experience included more than 20 ankles were defined experienced surgeons in this study. Thirteen ankles operated by inexperienced surgeons, with an experienced surgeon who participated as an assistant, were assigned to the inexperienced group. Fifteen ankles operated on by an experienced surgeon were assigned to the experienced group. TNK Ankle (Kyocera, Kyoto, Japan) was used for all experiments.The coronal and sagittal alignments and the size of the tibial component relative to the tibial shaft were measured. Preoperative and postoperative Japanese Society for Surgery of the Foot (JSSF) and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were used for clinical assessment. ResultsThere were two malleolar fractures during the operation in both groups, and there were no cases of revision surgery. There were no significant differences in the coronal and sagittal tibial component alignment and size between the groups. The JSSF and SAFE-Q improved. There were no significant differences between groups, except for the preoperative JSSF score. ConclusionsDuring the learning curve period, careful surgical indications and surgeries are desired. However, we found that when experienced surgeons participated as assistants, favorable results could be expected even when inexperienced surgeons performed the surgery. Level of evidenceⅢ

Supramalleolar Lateral Opening-Wedge Osteotomy in Conjunction With Progressive Collapsing Foot Deformity Reconstruction for PCFD With Ankle Instability.

Reconstruction of progressive collapsing foot deformity (PCFD) with ankle instability (PCFD class E) remains a substantial challenge to orthopaedic surgeons. We report the outcomes of PCFD class E treated by means of a relatively standard PCFD foot reconstruction approach with the addition of a supramalleolar lateral opening-wedge osteotomy. We conducted a retrospective study of 13 patients (15 ankles) who underwent this procedure for PCFD class E between 2010 and 2021. Mean follow-up time was 3.8 (range, 2-6.3) years. Clinical assessment was based on the Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot scale as well as a Self-Administered Foot Evaluation Questionnaire (SAFE-Q). Radiographic assessments, including identification of the mechanical ankle joint axis point and a modified valgus Takakura-Tanaka osteoarthritis grade, were recorded. The mean JSSF score improved significantly from 45.2 preoperatively to 83.9 postoperatively (P < .001). SAFE-Q scores at the final follow-up were 70.1 for the pain and pain-related subscale, 75.4 for the physical functioning and daily living subscale, 83.0 for the social functioning subscale, 74.4 for the shoe-related subscale, and 78.1 for the general health and well-being subscale. Radiographic measurements showed improvement in the tibiotalar tilt angle (average improvement: 5.4 degrees); orientation of the talus joint line relative to the ground (average improvement: 14.0 degrees); anteroposterior talus-first metatarsal angle (average improvement: 11.2 degrees), talonavicular coverage angle (average improvement: 21.6 degrees), and lateral talus-first metatarsal angle (average improvement: 17.0 degrees). Postoperatively, the mechanical ankle joint axis point moved medially for all patients and into the medial half of the ankle joint for 7 patients. The modified osteoarthritis stage improved postoperatively in most cases. In this select and relatively small group of patients who had a supramalleolar lateral opening-wedge osteotomy combined with PCFD reconstruction, we measured general improvement in JSSF scores and radiographic variables. Long-term durability of the procedure remains unknown. This procedure may be an option for preserving the ankle joint in treatment of PCFD class E with osteoarthritis of the ankle. Level IV, therapeutic.

Modified Scarf Osteotomy with Medial Capsular Interposition Combined with Metatarsal Shortening Offset Osteotomy: A Comparison of Patients with Noninflammatory Arthritis and Rheumatoid Arthritis of the Foot.

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. 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. 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. 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.

Bilateral and concomitant pathology’ surgeries do not affect the outcomes of mini-open distal linear metatarsal osteotomy (Bosch osteotomy) with manipulation for hallux valgus deformity

BackgroundBosch osteotomy for hallux valgus (HV) deformity has advantages of reduction both the operating time and surgical dissection, and may be performed bilaterally and with fewer complications than other surgical procedures as well as early weight-bearing. However, there are few reports on the effects of bilateral simultaneous surgery, simultaneous surgery on concomitant pathologies, and the preoperative HV angle on the postoperative results. The present assessed the factors that might affect the improvement in clinical outcomes following mini-open Bosch osteotomy with manipulation to treat HV deformity. MethodsSeventy patients with 110 feet were included. They were divided into groups as follows: unilateral and bilateral simultaneous surgery groups, Bosch osteotomy alone and simultaneous surgeries for concomitant pathologies groups, and preoperative HV angle< 40° and ≥ 40° groups. Subjective clinical outcome scores using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and the HV and intermetatarsal first and second metatarsal (M1M2) angles according to the anteroposterior (A-P) view of the weighted foot X-ray were assessed preoperatively and at 12 months after surgery. ResultsThe mean HV angle, M1M2 angle and all subscales of the SAFE-Q score showed significant improvement at 12 months after surgery, regardless of simultaneous bilateral surgery, simultaneous surgery for concomitant pathologies, or the preoperative HV angle. On comparing the groups, there were no significant differences in the HV angle at 12 months after surgery. Significant inferiority at 12 months after surgery was found in the intermetatarsal angle in the simultaneous surgery for concomitant pathologies group and in all subscales of the SAFE-Q score in the HV angle ≥ 40° group. ConclusionMini-open Bosch osteotomy with manipulation for HV deformity demonstrated good results in both radiological assessments and subjective clinical scores at 12 months after surgery, even for simultaneous bilateral surgery, simultaneous concomitant pathologies’ surgery, and severe HV deformity. Level of EvidencePrognostic Level III, retrospective cohort study.

Impact of pain in other body regions on the foot-specific quality of life in patients with hallux valgus.

The purpose of this study was to clarify the prevalence of pain outside the foot, and to determine the associations of pain outside the foot with foot-specific quality of life (QOL) in patients with hallux valgus. Patients scheduled to undergo hallux valgus surgery were recruited. Patients answered whether they experienced disabling pain in 13 body regions other than the foot. Foot-specific QOLwas assessed using the Self-Administered Foot Evaluation questionnaire (SAFE-Q). Foot pain was quantified using the visual analogue scale (VAS). Patient characteristics, including age, sex, comorbidity, anxiety, and depression, were also surveyed. The association between pain elsewhere and the SAFE-Q and pain VAS scores were assessed using univariate and multivariate analyses. Of 102 patients, 55 (54%) experienced pain other than the foot. All SAFE-Q subscale scores were lower, and pain VAS was higher in patients with pain elsewhere than in patients without. In the multivariate analysis, an increase in the number of pain regions was independently associated with a decrease in SAFE-Q scores and an increase in pain VAS. More than half of the patients with hallux valgus experienced pain elsewhere. The presence of pain elsewhere was associated with poorer foot-specific QOL and severer foot pain.

Outcome after resection arthroplasty or shortening oblique osteotomy of the lesser metatarsals combined with arthrodesis of the first metatarsophalangeal joint for severe rheumatoid forefoot deformities.

We investigated objective and patient-reported outcomes after resection arthroplasty or shortening oblique osteotomy (SOO) of the lesser metatarsals combined with arthrodesis of the first metatarsophalangeal (MTP) joint for severe rheumatoid forefoot deformities. 17 feet from 14 women (mean age, 67.8years) underwent resection arthroplasty of the lesser metatarsal heads (MTH resection group), while 13 feet from nine women and two men (mean age, 68.7years) underwent SOO of the lesser metatarsals (MTH preservation group). Arthrodesis of the first MTP joint was performed in all cases. Mean follow-up in the MTH resection and preservation groups was 25.0 and 21.3months, respectively. Preoperative and postoperative clinical evaluation included Japanese Society for Surgery of the Foot (JSSF) scale and self-administered foot evaluation questionnaire (SAFE-Q) scores. Mean total JSSF scale significantly improved from 53.4 to 76.4 in the MTH resection group (p < .001) and from 50.1 to 74.2 in the MTH preservation group (p = .002). Pain and pain-related and shoe-related SAFE-Q subscale scores significantly improved after surgery in both groups. In the MTH resection group, recurrence of painful callosities and claw toe deformity was observed in four and three feet, respectively. In the MTH preservation group, one patient experienced recurrence of painful callosities and one underwent revision surgery for IP joint dislocation. Resection arthroplasty or SOO of the lesser metatarsals combined with arthrodesis of the first MTP joint achieved significant improvement with respect to pain relief, deformity correction, and footwear comfort.

Minimally Invasive Surgery for Severe Hallux Valgus with Severe Metatarsus Adductus: Case Reports

Category:Bunion; Lesser ToesIntroduction/Purpose:Metatarsus adductus (MA) is a congenital transverse plane deformity with an incidence of approximately 30% in patients with hallux valgus. Operative treatment of hallux valgus (HV) with MA can be clinically challenging, and the recurrence rate of HV has been reported as two times higher than in patients without MA. Minimally invasive surgery (MIS) for the correction of HV is growing in popularity; however, only one study has been published on MIS for HV with MA using percutaneous proximal metatarsal osteotomy. We presented our case reports using distal oblique metatarsal minimal invasive osteotomy (DOMMO) for severe MA.Methods:We corrected two feet using DOMMO for severe MA. Minimally invasive chevron Akin osteotomy (MICA) was utilized to correct severe HV. The patient had subluxations in the second and third metatarsophalangeal joints and hammer toe deformities. Therefore, those deformities were concurrently corrected using percutaneous procedures. The patient was allowed immediate full weight bearing postoperatively in a flat rigid shoe for 6 weeks. Radiographic and clinical evaluations were performed preoperatively and one year after surgery. On the anteroposterior radiograph, the hallux valgus angles (HVA), the first intermetatarsal angles (IMA), tibial sesamoid positions (TSP) and metatarsus adductusangles (MAA) were evaluated. On the lateral weight-bearing radiograph, first metatarsal inclination angles were also evaluated. We also evaluate the Japanese Society for Surgery of the Foot (JSSF) hallux and lesser toes scales and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) both before and after MIS for HV with MA.Results:In the first case, the HVA improved from 50° to 16°, the IMA from 15° to 11°, TSP from 7 to 5 using Hardy's classification, and MAA from 27° to 14.5°, pre- to postoperatively. In the second case, the HVA improved from 45° to 11°, the IMA from 10° to 6.5°, TSP from grade 7 to 3, MAA from 30 to 12, pre- to postoperatively. The first metatarsal inclination angles changed from 16.9° and 18.8° to17.7° and 22.0°, respectively. All subluxations and hammer toe deformities were resolved. Although there were delayed unions in the lesser metatarsals, unions were achieved finally. Preoperative JSSF hallux scales and lesser toes scales were 59 points and 64 points, 67 points and 80 points, respectively. Both hallux and lesser toe scales improved to 100 points one year after surgery. All SAFE-Q subscores were also improved one year after surgery.Conclusion:In conclusion, our MIS procedure, consisting of DOMMO of the second, third, and fourth metatarsals and MICA, could correct severe HV with severe MA. The patient was allowed immediate full weight bearing postoperatively in a flat rigid shoe. Although there were delayed unions in lesser metatarsals, unions were finally achieved and good results were demonstrated both radiographically and clinically.
