Arthrodesis versus Arthroplasty of the First Metatarsophalangeal Joint in the Treatment of Hallux Rigidus - A Comparative Study of Appropriately Selected Patients / Artrodese versus artroplastia da primeira articulação metatarsofalângica no tratamento do hallux rigidus - Estudo comparativo de pacientes selecionados apropriadamente

Abstract Objective Historical results of arthroplasty of the first metatarsophalangeal joint (1MTP) are relatively poor; however, improvements in the understanding of the normal foot biomechanics, implant materials and design currently make arthroplasty a reasonable option in appropriately selected patients. The present study aimed to compare the clinical and radiographic results of 1MTP arthrodesis and arthroplasty in the treatment of hallux rigidus and to present a rationale for patient selection for arthroplasty. Methods A total of 36 patients (38 feet) with hallux rigidus submitted to surgery (12 arthrodesis and 26 arthroplasties) were prospectively included in the study. Pain was assessed using the visual analogue scale (VAS) and the functional status was assessed using the American Orthopedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal (AOFAS-HMI) scale. Complications and radiographic results were also analyzed, and survival rates were calculated for both procedures. Results All of the patients reported significant improvement in pain and functional status after surgery. Patients submitted to arthroplasty had better functional results on the AOFAS-HMI scale (89.7 versus 65.7 points; p < 0.001) and better pain relief (VAS 1.6 versus 3.9 points; p = 0.002) when compared with the group submitted to arthrodesis. There was one case of infection in the arthroplasty group and 2 cases of pseudarthrosis in the arthrodesis group. Conclusion Arthrodesis provides pain relief and satisfactory results but alters the biomechanics of gait. Like arthrodesis, arthroplasty improves pain significantly, being a more physiological alternative to preserve the biomechanics of the foot. While the two surgical methods yielded good clinical results, selected patients submitted to arthroplasty had better clinical scores and lower revision rates.

Resumo Objetivo Historicamente, os resultados da artroplastia da primeira articulação metatarsofalângica (1MTP) eram relativamente ruins; no entanto, melhorias na compreensão da biomecânica normal do pé, nos materiais e no design dos implantes, tornam a artroplastia um tratamento aceitável em pacientes selecionados. O presente estudo pretendeu comparar os resultados clínicos e radiográficos da artrodese com os da artroplastia da 1MTP no tratamento de hallux rigidus e apresentar um racional para seleção de pacientes para artroplastia. Métodos Um total de 36 pacientes (38 pés) com hallux rigidus operados (12 artrodeses e 26 artroplastias) foram prospectivamente incluídos. A dor foi avaliada com recurso à escala visual analógica (VAS) e o resultado funcional usando a escala American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal (AOFAS-HMI). As complicações e os resultados radiográficos foram também registrados e a taxa de sobrevida calculada para os dois procedimentos. Resultados Todos os pacientes referiram uma melhoria significativa na dor e nos resultados funcionais após a cirurgia. Os pacientes submetidos a artroplastia tiveram melhor resultado funcional na escala AOFAS-HMI (89,7 versus 65.7 pontos; p < 0.001) e melhor alívio da dor (VAS 1,6 versus 3,9 pontos; p = 0,002) quando comparados com os doentes submetidos a artrodese. Registrou-se um caso de infecção no grupo da artroplastia e 2 casos de pseudoartrose no grupo da artrodese. Conclusão A artrodese permite alívio da dor e resultados satisfatórios, mas altera a biomecânica da marcha. Tal como a artrodese, a artroplastia melhora a dor significativamente, sendo uma alternativa mais fisiológica para preservar a biomecânica do pé. Apesar dos dois tratamentos terem bons resultados clínicos, em pacientes selecionados, a artroplastia teve melhores resultados clínicos e menor taxa de revisão.

Artrodesis metatarsofalángica del hallux: comparación retrospectiva entre placa bloqueada y tornillos canulados / Hallux metatarsophalangeal arthrodesis: retrospective comparison between blocked plate and cannulated screws

Resumen: Introducción: Existen múltiples métodos e implantes utilizados para la artrodesis metatarsofalángica del hallux sin evidencia a favor de uno u otro en la bibliografía. El objetivo fue comparar los resultados clínicos y radiológicos de dos métodos e implantes utilizados en nuestro centro. Material y métodos: Revisión retrospectiva de 37 pies entre 2013 y 2017 (22 pies mediante placa y 15 mediante tornillos canulados). Se recogieron variables clínicas y radiológicas y se aplicaron las escalas AOFAS y Manchester-Oxford. Se estudiaron las variables descriptivas y analíticamente mediante el programa SPSS v15. Resultados: El grupo intervenido mediante placa lo compuso 77% de mujeres, con una edad media de 65 años y una distribución por diagnósticos de hallux valgus (HV) severo (36%), recidiva de hallux valgus (RHV) (36%) y hallux rigidus (HR) (28%), frente a 80% de mujeres, con media de 68 años y HVS (34%), RHV (46%) y HR (20%) en el grupo de tornillos canulados. No se encontró diferencias significativas en la corrección de los ángulos para HVS o RHV. La tasa de seudoartrosis dolorosa fue de 13% en ambos y la reintervención fue de 18% en el grupo de placas y 26% en el grupo de tornillos. Tanto la escala AOFAS como la M-O fueron mejores en el grupo de placa 63.8 versus 52.6 (p = 0.07); 30.1 versus 41.0 (p = 0.10); así como la satisfacción del paciente 86 versus 66% (p > 0.05) y el dolor postoperatorio 3.68 versus 5.58 (p > 0.05). Conclusión: Son grupos pequeños de estudio, sin aleatorización de implantes, ambas opciones son funcionales sin poder encontrar una preferente.

Abstract: Introduction: There are multiple methods and implants used for the metatarsophalangeal arthrodesis of hallux without evidence in favor of one or the other in the bibliography. The goal was to compare the clinical and radiological results of 2 methods and implants used in our center. Material and methods: Retrospective review of 37 feet between 2013 and 2017 (22 feet by plate and 15 by cannulated screws). Clinical and radiological variables were collected and the AOFAS and Manchester-Oxford scales were applied. Variables were studied descriptively and analytically through the SPSSv15 program. Results: The group intervened by plate was composed of 77% of women, with an average age of 65 years and a distribution by diagnosis of severe hallux valgus (HV) (36%), hallux valgus relapse (HVR) (36%) and hallux rigidus (HR) (28%), compared to 80% of women, 68 years old and HV (34%), HVR (46%) HR (20%) in the group of cannulated screws. No significant differences were found in the correction of angles for HV or HVR. The rate of painful pseudoarthrosis was 13% in both and the re-intervention was 18% in the plate group and 26% in the screw group. Both the AOFAS and M-O scales were better in the plate group 63.8 vs 52.6 (p = 0.07); 30.1 vs 41.0 (p = 0.10); as well as patient satisfaction 86% vs 66% (p > 0.05) and postoperative pain 3.68 vs 5.58 (p > 0.05). Conclusion: Small study groups, not implant randomization, both options are functional without being able to find a preferred one.

Forefoot disorders and conservative treatment / 영남의대학술지

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

Acquired Change and Pain of Foot in Elderly People

As the aging of the foot progresses, the stiffness of the soft tissues, the reduction of the range of motion, the decrease of the muscle strength, and the flattening of foot are manifested. These changes increase the risk of foot pain, the problem of weight distribution and transmission, and the risk of falls, resulting in secondary complications and lowering quality of life. The most common deformities and diseases of the elderly foot are hallux valgus, hammertoes, hallux rigidus, Achilles tendinitis, plantar fasciitis, metatarsalgia, hyperkeratosis, and other deformities of the feet caused by chronic conditions. Systemic diseases that promote these foot problems include diabetes, peripheral nerve damage, repetitive ankle ligament injuries, deformities due to fractures, and obesity. Understanding the mechanisms of aging and the processing of biomechanics in the elderly will enable them to reach a healthy life through appropriate rehabilitation, exercise and educations during aging. In addition, it is necessary to promote the healthy life in elderly by customized exercise, training, and shoes.

Shortening Scarf Osteotomy for Treatment of Hallux Rigidus Deformity / 대한족부족관절학회지

PURPOSE: To evaluate the effect of shortening scarf osteotomy on pain relief and range of motion (ROM) of the first metatarsophalangeal joint in hallux rigidus patients. MATERIALS AND METHODS: Twenty-three cases of 19 patients who had been treated with shortening scarf osteotomy for the hallux rigidus between January 2007 and December 2013 were reviewed. The mean follow-up period was 21.4 months, and the mean age was 59.2 years. The first metatarsal bone was shortened until the ROM of the first metatarsophalangeal joint was greater than 80° or 40° of dorsiflexion. The length shortened by scarf osteotomy was measured. The authors also measured and compared the joint interval difference of the standing foot using an anteroposterior radiography. Moreover, the difference of ROM of the first metatarsophalangeal joint between the preoperative and final follow-up periods was also compared. The clinical results were evaluated and compared using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and visual analogue scale (VAS) score. RESULTS: The mean shortening length was about 6.5 mm (range, 4∼9 mm). The joint space has been increased to 1.8 mm, and the ROM of the first metatarsophalangeal joint has also been increased to 18.4° after the operation. In three cases, the postoperative ROM has been decreased to less 10°. The AOFAS score has been improved from 41.7 (range, 32∼55) to 86.2 (range, 65∼95), and the VAS score was also decreased from 3.7 (range, 3∼5) to 1.3 (range, 0∼3). Two cases have shown no decrease in pain even after the operation. CONCLUSION: Shortening scarf osteotomy was found to decrease joint pain by decompressing the pressure of the first metatarsophalangeal joint. This osteotomy also helped improve the ROM of the first metatarsophalangeal joint. Shortening scarf osteotomy can be considered one of the effective methods for joint preservation.

Hallux Rigidus with Osteochondroma of the Hallucal Proximal Phalanx (A Case Report) / 대한족부족관절학회지

Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

The Distal Metatarsal Dorsal-Wedge Osteotomy Using Bio-Compression Screw for Advanced Hallux Rigidus / 대한족부족관절학회지

PURPOSE: This study was performed retrospectively to evaluate clinical outcomes of distal metatarsal osteotomy using bio-compression screw as the joint preservation method for advanced hallux rigidus. MATERIALS AND METHODS: Eleven cases were followed up for more than 1 year after distal metatarsal dorsal wedge osteotomy for advanced hallux rigidus. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society (AOFAS) score and patient's satisfaction score. The range of motion, and the period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were evaluated. As the radiographic evaluation, the interval of 1st MTP (metatarsophalangeal) joint space and the period to union were measured. RESULTS: The AOFAS hallux score had improved significantly from preoperative average 50.7 points to 87.6 points at the last follow-up (p=0.005). The subjective satisfaction score was average 90.6 points. There were no case of subsequent fusion or additional operation, and no complication associated with bio-compression screw. The period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were average of 24.8 weeks, 20.4 weeks, 16.8 weeks, 18.5 weeks respectively. Dorsiflexion of 1st MTP joint had improved significantly from preoperative average 17.5degrees to 44degrees (p<0.001). All cases achieved union of osteotomy site, and the period to union was average 10.4 weeks. The interval of 1st MTP joint space had improved significantly from preoperative average 1.2 mm to 3.5 mm (p=0.014). CONCLUSION: Distal metatarsal osteotomy using bio-compression screw seems to be one of effective treatment methods for advanced hallux rigidus, because of restoration of the first MTP joint motion, and reliable pain relief, and needlessness of hardware removal.

Resultados preliminares da prótese total metatarsofalângica METIS-Newdeal® / Preliminary results from the METIS-Newdeal® total metatarsophalangeal prosthesis

OBJETIVO: Avaliar os resultados preliminares da prótese METIS-Newdeal® como tratamento de hallux rigidus grau III/IV. MÉTODOS: Estudo prospectivo de oito próteses MTF colocadas em seis pacientes entre nov/2007 e jul/2009. A idade média foi de 55 anos e o tempo de seguimento após a cirurgia de 50 semanas. Na avaliação dos resultados foi utilizado o escore AOFAS-MTF e controle imageológico por radiografia. RESULTADOS: Verificou-se um aumento pontual significativo do escore AOFAS-MTF que passou de 42p pré-operatório para 82p após a cirurgia (↑1,95x), tendo sido ao nível da função o maior ganho. Radiologicamente não se identificaram intercorrências. Dos cinco pacientes operados, apenas um se mostrou descontente com a cirurgia, após o surgimento de infecção precoce no local cirúrgico, sendo que corresponde à única complicação pós-op encontrada. CONCLUSÃO: A artroplastia total metatarsofalângica METIS-Newdeal® apresenta resultados promissores no curto prazo. No entanto, é necessário avaliar um maior número de casos com um tempo de seguimento mais longo para que se possa obter conclusões mais consistentes.

OBJECTIVE: To evaluate the preliminary results from the METIS-Newdeal® metatarsophalangeal prosthesis for treating hallux rigidus grade III/IV. METHODS: This was a prospective study on eight metatarsophalangeal prostheses that were placed in six patients between November 2007 and July 2009. The patients' mean age was 55 years and the mean follow-up after the surgery was 50 weeks. The results were evaluated using the AOFAS-MTF score and x-ray images as controls. RESULTS: The AOFAS-MTF score increased significantly from 42p before the surgery to 82p after the surgery (↑1.95x), mainly due to improvement in the functional level. No intercurrences were identified radiologically. Among the five patients who underwent operations, only one expressed dissatisfaction with the surgery: this was expressed after early infection appeared at the surgical site, and it was the only postoperative complication found. CONCLUSION: Total metatarsophalangeal arthroplasty using METIS-Newdeal® presented promising short-term results. However, evaluations on a larger number of cases with a longer follow-up are needed in order to draw more consistent conclusions.

Study of relationship between low back pain relation and foot disorders

Low back pain [LBP] has a high prevalence in any society. Although the relation between LBP and foot disorders is improbable, however, knowing this subject that each part of the foot has a role in body balance and this has a significant relationship with cooperation of body muscles, and any change in foot parts can affect the entered forces to the muscles and change them. The purpose of this study was to determine the relation between chronic LBP and foot disorders in two groups of healthy and LBP affected subjects. This is a case-control study, in which the relation between LBP and some foot disorders like Hallux valagus, Hallax rigidus, flat foot, calf muscle tightness and foot dimensions in subjects with and without LBP was studied. These subjects were selected with simple nonrandomized sampling and there were 83 subjects in each group. Findings showed a significant relation between Hallux valgus, Hallux rigidus, flat foot and solcus tightness with chronic LBP, but no significant relationship between foot dimensions [except width of right sole] and gastrocnemius tightness with chronic LBP was found. According to these results it can concluded the foot and ankle disorders due to their effects on posture, balance and gait, in long time, may cause chroic LBP

Criterios terapeuticos en las patologias mas frecuentes del antepie / The treatment protocol in forefoot pathology

Nuestro trabajo comenzo en el año 1976, con el ingreso al Servicio de Ortopedia y Traumatologia de Institutos Medicos Antartida. Hemos confeccionado un protocolo terapeutico para el tratamiento de las afecciones ortopedicas mas frecuentes del antepie humano: hallux valgus, con o sin metatarso primo varo, metatarsalgia, dedos en garra y juanetillo de sastre. El tratamiento se basa en suprimir el dolor, corregir la estetica y preservar la funcion. Hacemos una reseña antropologica del desarrollo del antepie, describimos en forma breve la anatomia podalica de las zonas topograficas a tratar. Explicamos la fisiopatologia del hallux valgus, del juanetillo, de la metatarsalgia y de la garra digital podalica. Mostramos las distintas tecnicas que utilizamos y por que preferimos cada una de ellas, fundamentalmente nuestras preferencias con bases anatomofisiopatologicas (resumen truncado)
