Epidemiology of Dupuytren disease and Patients Undergoing Selective Fasciectomy / Epidemiologia da doença de Dupuytren e de pacientes submetidos a fasciectomia seletiva

Abstract Objective To describe the epidemiological and clinical profile of patients with Dupuytren disease treated by selective fasciectomy and the factors associated with the severity of the disease. Methods Retrospective descriptive observational study involving 247 patients with Dupuytren disease, from 2013 to 2019. Multivariate logistic regression was performed for data analysis. Results Most patients were male (83.8%), self-declared white (65.2%), alcoholics (59.6%) and 49% were smokers, with a mean age of 66 ± 9 years old, with 77.2% presenting symptoms of the disease after the age of 51 years old. Approximately 51.9, 29.6 and 17.3%, respectively, had arterial hypertension, diabetes mellitus and dyslipidemia comorbidities. Bilateral involvement of the hands was observed in 73.3% of the patients. The rate of intra- and post-selective fasciectomy complications was of 0.6 and 24.3%, respectively, with 5.2% of the patients needing reintervention after 1 year of follow-up. After multivariate analysis, males were associated with bilateral involvement of the hands (odds ratio [OR] = 2.10; 95% confidence interval [CI]: 1.03-4.31) and with a greater number of affected rays (OR = 3.41; 95% CI: 1.66-7.03). Dyslipidemia was associated with reintervention (OR = 5.7; 95% CI = 1.03-31.4) and bilaterality with a higher number of complications (35.7 versus 19.7%). Conclusion A low rate of reintervention and operative complications was observed in patients with Dupuytren disease treated by selective fasciectomy. Male gender was associated with severe disease (bilaterality and more than two affected rays), and dyslipidemia with reintervention.

Contractura de Dupuytren. Estudio de 33 casos en Colombia / Dupuytren's contracture. Study of SS cases in Colombia

RESUMEN Objetivo: Describir el comportamiento clínico y epidemiológico de la contractura de Dupuytren (CD) en la población colombiana y comparar nuestros resultados con otras series publicadas en la literatura. Materiales y métodos: Estudio descriptivo observacional de 33 casos de CD presentados en el hospital San Pedro y San Pablo de la Virginia, Risaralda, durante los últimos 6 arios. Los pacientes cumplieron con el diagnóstico de CD de acuerdo con el parámetro establecido. Se compararon los resultados con diferentes series de casos de CD publicadas en la literatura. Resultados: La edad promedio al momento del diagnóstico fue de 61,3 años con mayor prevalencia en hombres (64% de los casos). La forma de presentación más frecuente fue unilateral en mano derecha (73%), a diferencia de lo reportado en otras series, donde el compromiso usualmente fue bilateral. La diabetes mellitus fue la comorbilidad con mayor asociación a la CD (24,24%), hallazgo similar a lo publicado previamente. La mayoría de los pacientes requirió tratamiento quirúrgico. Conclusiones: La CD es una entidad de mayor ocurrencia en hombres de la sexta a la séptima década de la vida. La diabetes mellitus es la enfermedad que más se asocia a su aparición, sin encontrase diferencias entre los estudios realizados. En población colombiana no hay relación aparente con epilepsia. La presentación de la CD es variable, encontrándose en nuestra serie un mayor compromiso unilateral a diferencia de otras poblaciones donde la presentación usualmente es bilateral.

ABSTRACT Objective: To describe the clinical and epidemiological behavior of Dupuytren's contracture (DC) in the Colombian population, and to compare the results of this study with other series published in the literature. Materials and methods: A descriptive, observational study of 33 cases of DC presented at the Hospital San Pedro y San Pablo, La Virginia Risaralda, over the last 6 years. The patients were diagnosed with DC according to the established parameter. The results were compared against different series of DC cases published in the literature. Results: The mean age at diagnosis was 61.3 years, with a higher prevalence of men (64% of cases). The most frequent form of presentation was unilateral in the right hand (73%), unlike the reports from other series with usually bilateral involvement. Diabetes mellitus was the comorbidity most often associated with DC (24.24%), a finding similar to those of previous publications. Most patients required surgical treatment. Conclusions: DC is a condition that occurs more often in men in the sixth or seventh decade of life. Diabetes mellitus is the most frequently associated disease, with no differences being found among the various studies. In the Colombian population there is no apparent association with epilepsy. The presentation of DC is variable, but our series showed more unilateral involvement as compared to other populations where the presentation is usually bilateral.

Collagenase Clostridium Histolyticum Injection for Dupuytren Contracture: 2-Year Follow-up

BACKGROUND: Dupuytren disease is characterized by the development of palmar fibrous tissue that can lead to fixed flexion contracture (FFC) and contribute to functional loss of the involved digits. Our goal was to investigate rates of contracture resolution and recurrence in patients who underwent enzymatic fasciotomy for Dupuytren contracture consisting of collagenase clostridium histolyticum (CCH) injection followed by passive manipulation combined with splinting and home-based therapy. METHODS: We prospectively enrolled 34 patients (44 metacarpophalangeal [MCP] and 33 proximal interphalangeal [PIP] joints) treated by one orthopaedic hand surgeon between November 2010 and November 2014. On day 1, CCH was injected into a palpable fibrous cord of the involved fingers. The next day, the finger was passively extended to its maximal corrective position. FFC was measured for each joint before injection and immediately after manipulation. Patients were instructed to wear an extension splint at night and perform stretching exercises at home and were re-evaluated at 6 weeks, 4 months, 1 year, and 2 years. Resolution was defined as improvement of contracture to ≤ 5° of neutral. Recurrence was defined as an increase in FCC of ≥ 20° after treatment. RESULTS: Immediate contracture resolution occurred in 42 of 44 MCP joints (p < 0.001), improving from 50° to 1.5°, and in 14 of 33 PIP joints (p = 0.182), improving from 44° to 16°. Four joints had recurrence within 6 weeks. Of the 48 joints with minimum 4-month follow-up (mean, 26 months), 12 had recurrence at 2-year follow-up (MCP, 6; PIP, 6). At 2-year follow-up, MCP and PIP contractures measured 17° and 35.5°, respectively. Older age and multiple digit involvement were associated with higher recurrence rates. CONCLUSIONS: CCH offers a safe, nonoperative option to correct FCC in Dupuytren disease with greater success for MCP joints compared to PIP joints. There is a tendency of reoccurrence within 2 years of treatment. Further investigation is needed to determine optimal timing of repeat CCH injection to improve upon or extend the period of contracture resolution.

Clinical Results of Subtotal Fasciectomy for Treatment of Dupuytren Contracture / 대한정형외과학회잡지

PURPOSE: In the treatment of Dupuytren's contracture, the aim of optical treatment is to lower the recurrence rate and reduce complications. This paper reports the results of subtotal fasciectomy in Dupuytren's contracture, extending the excision of palmar fascial structures from the diseased to normal appearing adjacent fascial structure. MATERIALS AND METHODS: From 2007 to 2017, 45 patients with Dupuytren's contracture treated by subtotal fasciectomy were reviewed retrospectively. The mean follow-up period was 45.9 months. Ninety-two digits were involved (index: 2, middle: 10, ring: 44, little: 36). The predisposing factors and affected joint were reviewed and the preoperative and postoperative contracture was measured. For clinical results, quick disabilities of the arm, shoulder, and hand (quick DASH) were used. Complications, including wound or skin problems, nerve injuries, hematoma, and complex regional pain syndrome, were assessed. RESULTS: Preoperative flexion contracture was 43.2° in the proximal interphalangeal joint and 32.9° in the metacarpophalangeal joint. In nine cases, patients had residual contracture of 9.7° (range, 5°–20°) on average and if the total number of cases were included, the mean residual contracture was 2.3° on average. The quick DASH score at the 12 months follow-up was 12.4. The overall complication rate was 26.6%. CONCLUSION: Subtotal fasciectomy can be a good surgical treatment option for Dupuytren's contracture with a low recurrence and low complication rate compared to other open procedures.

Resultados a tres años de seguimiento de Fasciotomía percutánea con aguja en enfermedad de Dupuytren / Results after three years of follow-up of percutaneous fasciotomy with needle in Dupuytren's disease

Dupuytren's disease is the abnormal and progressive proliferation of the palmar fascia, its etiology remains unknown. Percutaneous needle fasciotomy is a minimally invasive procedure, where hypodermic needles are used as a scalpel blade to break the pathological cord in Dupuytren's disease. OBJECTIVE: To evaluate the results of percutaneous needle fasciotomy in patients with 3-year follow-up METHODS: Percutaneous needle fasciotomy was performed in patients from the regional hospital of Talca from January 2014 to January 2017, pre and post-procedure contracture measurement was performed, followed up at 6 weeks, 3 months and annually up to three years. there was a registry of complications, recurrence and functional results with the QuickDASH scale. RESULTS: Of the 17 patients chosen, 13 completed the follow-up. 15 fingers (5 little fingers, 9 ring fingers, 1 middle) and 23 joints. The metacarpophalangeal joints achieved an immediate correction of 89%, maintaining a correction of 48% at three years. The proximal interphalangeal joint achieved a correction of 62%, maintaining 32% at the end of the follow-up. The QuickDash managed to descend from 39.4 to 21.5 points. There was recurrence of 35.7% in the metacarpophalangeal joints and 42.8% in proximal interphalangeal joints. We found that percutaneous fasciotomy is a treatment option.

3-Dimensional fasciectomy: A highly efficacious common ground approach to Dupuytren's surgery

BACKGROUND: Numerous Dupuytren’s fasciectomy techniques have been described, each associated with unique surgical challenges, complications and recurrence rates. We describe a common ground surgical approach to Dupuytren’s disease; 3-dimensional fasciectomy (3DF). 3DF aims to address the potential contributors to the high recurrence rate of Dupuytren’s disease and unite current limited fasciectomy practice that varies considerably between surgeons. METHODS: We describe the 3DF principles; raising thin skin flaps (addressing dermal involvement), excising diseased palmar fascia with a 3−5 mm clearance margin (treating highly locally recurrent conditions) and excising the vertical septae of Legueu and Juvara (providing deep clearance, hence addressing all potentially involved pathological tissue). The surgical outcomes between traditional limited fasciectomy (LF) and 3DF are compared. RESULTS: From the 786 operations included (n=585), postoperative recurrence rates were significantly lower for the 3DF group (2/145, 1.4%) than the LF group (72/641, 11.2%) (P=0.001), and the time to recurrence was significantly longer (5.0±0 years vs. 4.0±0.2 years; P < 0.0001). With recurrence excluded, there were no differences between the postoperative complication rates for 3DF (5/145, 3.5%) and LF (41/641, 6.4%) (P=0.4). CONCLUSIONS: Our results suggest that 3DF leads to lower recurrence rates and a longer disease-free period for patients, without increasing complications. 3DF provides a safe, efficacious, common ground surgical approach in the treatment of Dupuytren’s flexion deformity.

The Epidemiology of Dupuytren's Disease in Korea: a Nationwide Population-based Study

BACKGROUND: To date, there have been few reports on the nationwide population-based epidemiology of Dupuytren's disease (DD). We investigated the prevalence and incidence of DD in Korea using the large dataset provided by the Korean Health Insurance Review and Assessment Service. This study is the second nationwide epidemiological study of DD after the study in Taiwan. METHODS: Records of patients diagnosed with DD between 2007 and 2014 were extracted from the large dataset by diagnostic code searching (International Classification of Disease 10th revision code M72.0) and were included in the study. We calculated the prevalence and incidence of DD based on the total population of Korea provided by the Korean Statistical Information Service. Diseases associated with DD and the trends in surgery for DD were also analyzed. RESULTS: A total 16,630 patients were diagnosed with DD during the study period. The mean annual prevalence was 32.2 per 100,000 population (41.8 per 100,000 for men; 22.5 per 100,000 for women). The mean annual incidence was 1.09 per 100,000 population (1.80 per 100,000 for men; 0.38 per 100,000 for women). The common diseases associated with DD were hypertension (30.5%), diabetes mellitus (26.7%), hyperlipidemia (20.4%), ischemic heart disease (7.9%), and cerebrovascular disease (4.6%). The mean annual proportion of the patients who had surgery for DD was 5.24% of all DD patients. CONCLUSION: The prevalence and incidence of DD in Korea were 100–1,000 times lower than those in western countries; however, it was slightly larger than that in Taiwan.

Radiotherapy, a New Treatment Option for Non-malignant Disorders: Radiobiological Mechanisms, Clinical Applications, and Radiation Risk

Radiotherapy is used to treat not only malignant tumors but also benign inflammatory and hypertrophic diseases. Because of concerns about the potential hazards of irradiation, physicians in many countries, especially in North America, ruled radiotherapy out of medical practice for non-malignant diseases. Low-dose radiotherapy modulates the inflammatory response, providing an anti-inflammatory effect. Many researchers have reported low-dose radiotherapy efficacious for degenerative and inflammatory diseases. There are broad potential clinical indications for radiotherapy of non-malignant diseases. The general indications for radiotherapy for non-malignant disorders are acute/chronic painful degenerative diseases, such as chronic or acute painful osteoarthritic diseases of various joints; hypertrophic (hyperproliferative) disorders of soft tissues, such as early stages of Morbus Dupuytren and Ledderhose, keloids and pterygium; functional diseases, such as dysthyroid ophthalmopathy and arteriovenous malformations; and others, such as prophylaxis of heterotopic ossification. Radiotherapy for non-malignant disorders may be safely and effectively used, especially in older patients who suffered from these disorders and those who are reluctant to use other treatment options.

Síndrome de la mano diabética, a propósito de tres casos con limitación de la movilidad articular y lesiones complicadas del pie / A propos of three cases of diabetic hand syndrome with limited joint mobility and complicated foot injures

Introducción: La diabetes mellitus está asociada a una gran variedad de alteraciones músculo esqueléticas en las manos. El término síndrome de la mano diabética aparece con frecuencia en la literatura médica, aunque no existe una definición precisa, y hasta la fecha no se ha reconocido como una complicación específica de la enfermedad. El examen físico para la identificación temprana de estas alteraciones podría evitar la discapacidad de las formas severas.Objetivos: describir las alteraciones músculo esqueléticas más frecuentes en las manos de las personas con diabetes, a propósito de 3 pacientes con limitación de la movilidad articular, hospitalizados por lesiones complicadas del pie.Desarrollo: entre las alteraciones más frecuentes de la mano en las personas con diabetes está la limitación de la movilidad articular, la contractura de Dupuytren, el dedo en gatillo, la neuropatía ulnar y el túnel carpiano. Cada una tiene sus particularidades y pueden ser fácilmente diagnosticadas con el examen físico. Se asocian con la duración de la enfermedad, el pobre control metabólico y la presencia de complicaciones microvasculares, como en los casos que se presentan, con limitación de la movilidad articular severa. Estas deformidades afectan las actividades de la vida diaria, y por tanto, la calidad de vida de los pacientes, además, orientan al médico en la búsqueda de complicaciones microvasculares no diagnosticadas, de ahí la importancia de detectarlas.Conclusiones: se establece que la identificación temprana de las alteraciones en las manos de los diabéticos tiene importantes implicaciones individuales y sanitarias, por lo que su examen periódico debe ser realizado a todos los pacientes(AU)

Introduction: Diabetes mellitus is associated to a variety of musculoskeletal alterations in hands. The term diabetic hand syndrome frequently occurs in medical literature, although there is no exact definition and to date, it has not been recognized as specific disease complication. The physical exam for early detection of these alterations might prevent severe disability.Objectives: to describe the most common musculoskeletal alterations in diabetic persons’ hands using 3 patients with limited joint mobility who were hospitalized because of complicated foot injures.Development: among the most common hand alterations observed in diabetic persons are limited joint mobility, Dupuytren’s contracture, ulnar neuropathy and Carpal tunnel syndrome. Each of them has its own particularities and may be easily diagnosed through physical exam. They are related to length of disease, poor metabolic control and microvascular complications as it happens in the present cases with severe limited joint mobility. These deformities affect daily life activities and the quality of life of patients. Additionally, they guide the physicians in searching undiagnosed microvascular complications, hence the importance of detecting them.Conclusions: the early detection of hand alterations in diabetics has significant personal and health implications, so a systematic exam is required to be performed in all the patients(AU)

Colgajo comisural palmar: su utilidad en el abordaje de la enfermedad de Dupuytren con compromiso de dedos contiguos / Commissural palmar flap: use in Dupuytren`s disease involving adjacent fingers

Introducción: El diseño de las incisiones en la enfermedad de Dupuytren es probablemente el detalle técnico más importante en el tratamiento quirúrgico. El objetivo de este trabajo es realizar una valoración retrospectiva de la utilidad del colgajo comisural palmar en el abordaje de la enfermedad de Dupuytren con compromiso de dedos contiguos. Materiales y Métodos: Entre abril de 2009 y diciembre de 2012, los autores operaron a 32 pacientes con enfermedad de Dupuytren. Se incluyeron 12 pacientes con compromiso de, al menos, 2 dedos contiguos y el diseño de un colgajo comisural palmar. Se evaluaron entre los días 3-5, 15-21, 45-60 y a los 6 meses posoperatorios. Al final del seguimiento, se constataron las recidivas, la satisfacción y el puntaje Quick DASH. Resultados: Se realizaron 13 colgajos comisurales palmares en 12 pacientes, 6 manos derechas y 6 izquierdas. Los rayos contiguos afectados fueron el 4.° y 5.° dedos (8 casos), el 3.°, 4.° y 5.° dedos (3 casos), y el 3.° y 4.° dedos (un caso). La distancia promedio del colgajo comisural palmar comisura-vértice fue de 2,23 cm (rango 1,2-4,3) y la transversal, de 2,42 cm (rango 1,6-3,8). Siempre se pudo realizar la resección de las cuerdas patológicas y la fasciectomía parcial sin complicaciones intraoperatorias. Hubo una necrosis distal parcial, tratada con técnica de palma abierta. Conclusiones: El colgajo comisural palmar es de fácil disección y seguro a causa de su múltiple vascularización, permite una correcta visualización de las estructuras vasculonerviosas digitales y las bandas patológicas, útil en afección de dedos contiguos.

Background: In Dupuytren's contracture deciding the type of surgical incision is extremely important, and several options were described. The aim of this study is to evaluate retrospectively the usefulness of palmar commissural flap in Dupuytren's disease with adjacent fingers involvement. Methods: Between April 2009 and December 2012, 32 patients with Dupuytren's disease were operated on by the authors. Twelve patients with at least 2 adjacent fingers involvement and the design of a palmar commissural flap. The flaps were evaluated at days 3-5, 15-21, 45-60, and 6 months post-surgery. At the end of the follow-up, recurrence, satisfaction and Quick Dash score were evaluated. Results: Thirteen palmar commissural flaps were performed in 12 patients (6 right hands and 6 left hands). The affected adjacent rays were the 4th and 5th fingers (8 cases); the 3rd, 4th and 5th fingers (3 cases), and the 3rd and 4th fingers (one case). Average distances of the palmar commissural flap, commissure-vertex was 2.23 cm (range 1.2-4.3), and that of the transverse 2.42 cm (range 1.6 to 3.8). In all cases it was performed according to preoperative planning resection of pathological cords and partial fasciectomy. One case presented distal necrosis, which was treated with open palm technique. Conclusions: The palmar commissural flap can identify both the digital pedicle as pathological structures. Its vascularization makes it a safe and easy flap dissection.
