Comparison of Resorbable and Non-Resorbable Osteosynthesis Material in Hallux Surgery: A Systematic Review.

There are various pathologies that involve the hallux, among which hallux valgus is the most common. When conservative treatment fails, it is necessary to resort to a surgical approach. The fixation elements for osteotomies in the hallux are usually composed of metallic materials; however, today, there are numerous resorbable materials that offer numerous advantages over conventional materials. In this article, the objective is to analyze the scientific evidence through the systematic analysis of the existing literature in relation to the effectiveness of resorbable versus non-resorbable osteosynthesis material in the surgical correction of hallux deformities and compare the complications as well as the patient satisfaction and quality of life between both fixation methods. A systematic review of the literature available in the PubMed, EMBASE, Web of Science and Scopus databases and 10 studies were included. The documents were chosen following the eligibility and exclusion criteria, including experimental and observational studies evaluated with the Jadad and Newcastle-Ottawa methodological quality scale, respectively. Data were extracted from valid studies for the review, and the variables functionality, pain, angular corrections, complications, satisfaction and quality of life were observed. In conclusion, there is limited scientific evidence regarding the effectiveness of resorbable versus non-resorbable osteosynthesis material in the surgical correction of hallux deformities. All observed variables are similar regardless of the surgical technique and osteosynthesis material used.

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

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

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

Impact of foot health behavior among ethnic minority populations: A cross-sectional population-based study.

OBJECTIVE: To analyze the impact of the foot health and health behavior and the characteristics of outdoor footwear among minority ethnic groups. DESIGN AND MEASURES: A cross-sectional study design using the Foot Health Status Questionnaire: foot pain, foot function, shoe, general foot health, general health, physical activity, social capacity, and vigor. Outcomes included the self-reported type of outdoor footwear and clinical characteristics by sex were collected in 2019-2020. SAMPLE: A total of 78 Roma participants self-identified as members of this ethnic minority and 72 participants non-Roma were assessed (n = 150). RESULTS: The lower score values was recorded in the footwear and general foot health domains in Roma population. General population obtained higher scores in general health domains. The most common outdoor footwear types were running shoes and walking shoes in non-Roma population, versus flip flops and slippers in Roma population. Clinical characteristics did not show any statistically significant differences (p < .05). CONCLUSION: Roma people wear flip flops and slippers and non-Roma people running shoes and walking shoes. These findings reveal cultural differences that make it easier for the Roma population to experience a greater burden of foot health problems. General foot health and foot pain dimensions show statistically significant differences among ethnicity.

Effect of Phenol Application Time in the Treatment of Onychocryptosis: A Randomized Double-Blind Clinical Trial.

BACKGROUND: In the treatment of Onychocryptosis, chemical matricectomy with 88% phenol solution is one of the most common surgical procedures due to a recurrence rate of less than 5%, but it may produce a delay in healing time. The objective was to compare the healing time between phenol applications of 30 or 60 s. METHODS: A comparative, prospective, parallel, randomized, and blinded clinical trial was registered with the European Clinical Trials Database. Twenty-seven patients (54 feet) with 108 affected nail folds were randomized and treated with chemical matricectomy with phenol. Each hallux was randomly assigned to one of two groups (60 vs. 30 s phenolization). Each patient and one investigator were blinded to the phenol application time in each foot. The outcome measurements were healing time, recurrence, pain, post-surgical bleeding, inflammation, and infection rate. RESULTS: The 30 s application presents a shorter healing time (14.93 ± 2.81 days vs. 22.07 ± 3.16 days; p < 0.001) with a similar recurrence rate (p = 0.99). Post-operatory bleeding, pain, inflammation, and the infection rate did not show significant differences (p > 0.05). CONCLUSIONS: The 30 s phenol application time offers a shorter healing time than 60 s without affecting the effectiveness of the procedure, showing the same rate of complications.

Medium-Term Outcomes of Chevron Osteotomy for Hallux Valgus Correction in a Spanish Population: Radiologic and Clinical Parameters and Patient Satisfaction.

BACKGROUND: Chevron osteotomy for mild and moderate hallux valgus obtains good effects. It is suitable for a variety of cases, allowing for a significant degree of correction. This study aimed to investigate chevron osteotomy for the correction of hallux valgus in the medium-term by podiatric surgeons. It considers clinical and radiologic findings and patient perspectives and level of satisfaction. METHODS: Forty-five patients (50 feet) were assessed preoperatively, postoperatively, and at final follow-up. Mean patient age was 59.43 years (range, 32-80 years). The protocols include medical record review, clinical examination, and radiologic assessment. Anteroposterior weightbearing radiographs were analyzed preoperatively and at final follow-up. Clinical effects were analyzed with visual analog scale and American Orthopaedic Foot and Ankle Society (AOFAS) scores. RESULTS: Interobserver and intraobserver reliability were evaluated. Mean ± SD hallux valgus angle decreased at final follow-up (25.30° ± 7.21° versus 17.25° ± 10.32°; P = .041). There was no significant reduction in mean ± SD intermetatarsal angle at final follow-up (13.13° ± 3.03° versus 7.65° ± 3.47°; P = .078). Final AOFAS score was 82.08 ± 17.66. This study showed the relevance of magnet therapy, nail surgery, and other procedures. No patient was dissatisfied with the aesthetic scarring. CONCLUSIONS: The radiologic results at final follow-up were not compatible with relapse of the deformity. The definitive clinical results and the degree of patient satisfaction achieved with this technique were favorable from the patients' point of view.

The Treatment of Ingrown Nail: Chemical Matricectomy With Phenol Versus Aesthetic Reconstruction. A Single Blinded Randomized Clinical Trial.

BACKGROUND: In onychocryptosis surgery, incisional and non-incisional matricectomy is indicated according to the stage. The chemical matricectomy with 88% phenol solution is the gold standard and a wedge resection is indicated for more advanced stages. The aesthetic reconstruction has the advantages of the incisional procedure without eponychium incisions and an effectiveness similar to the chemical matricectomy with phenol. OBJECTIVE: To compare the recurrence and the healing time between the chemical matricectomy with phenol and the aesthetic reconstruction. METHODS: A comparative, prospective, parallel, randomized, and one-blinded clinical trial was registered with the European Clinical Trials Database (EudraCT) with identification number 2019-001294-80. Thrity-four patients (56 feet) with 112 onychocryptosis were randomized in two groups. Thirty-six were treated with chemical matricectomy with phenol and 76 with aesthetic reconstruction. Each patient was blind to the surgical procedure assigned by the investigator. The primary outcome measurements were healing time and recurrence. The secondary outcome measurements were post-surgical bleeding, pain, inflammation, and infection rate. RESULTS: The aesthetic reconstruction procedure presents a shorter healing time (8.2 ± 1.4 days vs. 21.3 ± 3.1 days; p < 0.001) with a similar recurrence rate (p = 0.98). Post-operatory bleeding, pain, inflammation, and the infection rate did not show significant differences (p > 0.05). CONCLUSIONS: The aesthetic reconstruction presents a shorter healing time, favoring the patients' recuperation, with a recurrence similar to the chemical matricectomy with 88% phenol solution.

Relationship between the presence of abnormal hallux interphalangeal angle and risk of ingrown hallux nail: a case control study.

BACKGROUND: Many risk factors have been identified to be associated with ingrown toenail. Internal pressure by the distal phalanx of the hallux and the second toe and external compression from the shoes has been proposed as a reason for the pathology. The main objective of the study was to analyze the existence of a correlation between the presence of pathological hallux interphalangeal angle (HIA) and risk of ingrown hallux nail. METHODS: One hundred and sixty-five subjects (312 ft) were enrolled in a cross-sectional, analytical and observational case-control study. A radiographic computerized system was used to measure HIA in both groups. The angle was considered as the sum of three angles, obliquity, asymmetry and joint deviation. RESULTS: The mean HIA in case group subjects (patients with hallux ingrown nail) was significantly higher than that obtained in control group subjects (17.39 ± 6.0° versus 13.47 ± 4.6°, p = .036). A total of 73.71 and 46.79 % of feet presented an angle equal or greater than 13.47° in the onychocryptosis and control group, respectively. CONCLUSIONS: The results show a correlation between the variables analysed. The presence of an HIA greater or equal than 14.5° may be a predisposing factor for developing onychocryptosis of the hallux. Clinicians treating individuals with pathology in hallux might use a baseline cutoff of HIA equal than 13.5°.

Implementation of the WHO "Safe Surgery Saves Lives" checklist in a podiatric surgery unit in Spain: a single-center retrospective observational study.

BACKGROUND: The Surgical Safety Checklist (SSC) is a tool developed by the World Health Alliance for Patient Safety, to assist health professionals in improving patient safety during surgery. Numerous specialties have incorporated this into their clinical practice. The purpose of this study is to adapt and implement this tool within the field of podiatric surgery and to evaluate its impact upon safety standards and post-surgical complications. METHODS: An analytical, observational, longitudinal study has been performed retrospectively. The implementation of the Surgical Safety Checklist in podiatric surgery took place over a 10-month period. The sample is made up from the medical histories of patients who were operated on (n = 134) in the University of Seville's podiatric clinic. The sample was divided into three groups: those prior to the implementation process (65 subjects), those after the implementation process: without the SSC (35 subjects) and those with the SSC (34 subjects). The safety standards included in the tool were analysed in conjunction with the results and post-operative complications. RESULTS: An improvement was seen in compliance with the Prophylaxis Protocol and the correct completion of the Informed Consent (p = 0.00), as well as a statistically significant relationship between the correct use of antibiotic prophylaxis and the use of the Surgical Safety Checklist (p = 0.049). The results demonstrate a reduction in the number of post-operative days (p = 0.012). No cases of surgery being performed in the wrong place were found in this study. CONCLUSIONS: The Surgical Safety Checklist allows us to improve compliance with the safety protocols recommended by the scientific community, and consequently to reduce the incidence of complications related to surgery and to improve patient safety during elective podiatric surgery.

Hallux interfalándico patológico e incidencia de los distintos grados de onicocriptosis / Pathologic interphalangeal hallux and the incidence of the different stafes of onycochryptosis

El objetivo de este estudio es demostrar la correlación existente entre la patología de Onicocriptosis y la presencia de Hallux interfalángico patológico. Algunos conceptos claves que debemos manejar son el de Hallux Abductus interfalángico del primer dedo y Onicocriptosis, cuya etiología es muy variada. La muestra del estudio está formada por un total de 312 pies pertenecientes a 156 sujetos, de los cuales son 189 mujeres y 123 hombres. El tipo de estudio diseñado es un estudio transversal, analítico, observacional y de caso y control. Los resultados del valor medio de HIF del grupo de estudio son de 17,39“. El valor medio de HIF del grupo control es de 13, 47“. Nuestros resultados muestran que en el grupo de estudio el 73,71% presentan valores de HIF por encima del valor de 13,47“. El valor de HIF no influye en el mayor o menor grado de afectación de onicocriptosis. La mayoría de los pacientes, casi el 60% presentan onicocriptosis de grade 1. Y la mayoría de los casos presentan afectación de los bordes tibial y peroneal. La afectación es mayor en mujeres que en hombres siendo de más del doble para la afectación del borde tibial y peroneal. Como conclusiones de este estudio podemos extraer que existe un alto grado de correlación entre la presencia de HIF patológico y Onicocriptosis. Los pacientes con onicocriptosis tienen un ángulo interfalángico significativamente superior a aquellos que no lo padecen. Los grados de Onicocriptosis más frecuentes son los estadios 1° y 2°. E1 valor medio del H.I.F de este estudio es de 13,47“. No existen resullados significativos para la variables edad y sexo de la muestra. El valor dc HIF no influye en el mayor 0 menor grado de afectación de onicocriptosis (AU)

The aim of this study is to prove the possible relation between onycochryptosis and the pathologic interphalangeal Hallux. Some of the key concepts that we must take into account are interphalangeal Hallux Abductus of the first toe and onycochryptosis, whose etiology is very wide. The sample of this study is 312 feet belonging to 156 subjects, of which 189 are women and 123 men. We conducted a transverse, analytical, observational, case-control study. The mean value of the PIH of the study group is 17,39“ whereas, the mean of the control group is 13, 47". Our results show that in the study group, 73,71% present a PIH value higher than 13,47”. PIH value does not influence the major or minor degree of affectation of onycochryptosis. Most of the patients, almost 60% present onycochryptosis of stage 1. And the majority of the cases present affectation of the tibial and peroneal edges. The affectation is higher in women than men, being more than twice the affectation of the tibial and peroneal edge. As conclusions, we can state that there is a high degree of correlation between the presence of PIH and onycochryptosis. Patients with onycochryptosis have an interphalangeal angle significantly superior to those who do not suffer this condition. The most frequent degrees of onycochryptosis are stage 1 and 2. The mean value of the PIH of this study is 13,47“. We could not find significant results related to age and sex. PIH Value does not influence the major or minor degree of affectation (AU)
