RESUMO

OBJECTIVE: To present the functional results obtained and the possible surgical difficulties after the surgical treatment of Dupuytren's disease (DD) recurrence in patients previously treated with Clostridium histolyticum (CCH) collagenase. MATERIALS AND METHODS: In this prospective study, 178 patients with DD were treated with CCH from 2011 to 2018; During long-term postoperative follow-up, 34 patients (19.1%) had recurrence of DD. In all patients injected in the IFP the disease recurred; In patients injected in the MCP, recurrence was highest in grade III and IV of the Tubiana classification, with involvement of the 5th finger and the two-finger Y-chord. Fourteen patients (7,8%) required surgery by partial selective fasciectomy due to recurrence of cord DD infiltration. The clinical and functional results of the patients, the difficulty of the surgical technique and the anatomopathological analysis of the infiltrated cords were evaluated in comparison with those of cords and patients who had had no previous CCH treatment. RESULTS: In all patients, cord rupture was achieved after injection, reducing joint contracture. In 14 patients, we observed during the follow-up the existence of DD recurrence that required surgical treatment by selective partial fasciectomy. There were no major difficulties in surgery and good clinical and functional results at 6 months of follow-up. The anatomopathological study of the resected tissue did not present histological alterations with respect to the samples obtained from patients initially treated by selective partial fasciectomy. CONCLUSIONS: Selective fasciectomy after CCH injection does not lead to important operative difficulties, as long as the CCH injection is performed according to the recommendations. There were no histological changes in the tissue after CCH injection. LEVEL OF EVIDENCE: III.

RESUMO

INTRODUCTION: Our purpose with this publication is to document the survival of uncemented and unconstrained total trapeziometacarpal arthroplasty after energy trauma to the upper extremity. MATERIAL AND METHODS: From 1999 to the present, ten patients carrying total TMC arthroplasty suffered major traumatic injuries on the hand. Eight patients had fractures of the distal radius, one patient had scapho-lunate dissociation and one patient had a dorsal pullout of the triquetrum. A clinical and radiological examination of the patients after the trauma was carried out and compared with the pre-traumatic prosthesis status. RESULTS: Three patients required surgical intervention for the associated traumatic injury. The postraumatic clinical and functional follow-up of the patients was good, and no differences were documented with respect to mobility, strength and pain at the level of the thumb with respect to the prior to the trauma. No signs of loosening, instability or alteration in the alignment of the components of the protheses were observed in the radiological examinations following the trauma. CONCLUSIONS: There is a high survival rate of uncemented total trapeziometacarpal arthroplasty in the long term, even in the face of energy trauma. It is then a safe implant. Despite of being non-constrained, a good alignment of the prosthetic components is the key to avoid dislocation of the prosthesis.

RESUMO

PURPOSE: Evaluate the Scratch Collapse Test in an objective way, by replacing the subjective evaluation made by the physician with an objective evaluation measure, made with a digital dynamometer. METHODS: Observational study carried out, in 90 patients divided into three groups of 30 patients, taking into account the electromyographic study of the median nerve in the carpal tunnel (no alteration, moderate, severe).The external rotation of the shoulder was measured in four different situations (no scratch, scratch over the carpal tunnel, scratch in the dorsum of the wrist and scratch in the shoulder). RESULTS: There were no statistical differences in the result of the strength in any of the four different situations in patients without carpal tunnel of with moderate carpal tunnel syndrome. However, there were statistical differences between the basal measurement (without scratching) and the measurement after tunnel scratching in patients with severe carpal tunnel syndrome. But this statistical difference was only 0.08 kg in the average measure, and this difference is clinically undetectable and far for producing a real collapse of the external rotation of the shoulder. CONCLUSION: The Scratch Collapse Test is not a valid diagnostic exam for carpal tunnel syndrome if the strength is measured in an objective manner.

RESUMO

Objetivo. El propósito de este estudio es mostrar los resultados obtenidos con el empleo de la artroplastia de recubrimiento con anclaje escafoideo en el tratamiento de la artrosis escafotrapeciotrapezoidea (ETT) aislada. Material y método. Se realiza un estudio observacional, descriptivo y retrospectivo del tratamiento de 10 pacientes con artrosis ETT aislada sintomática durante los años 2013 a 2015. El seguimiento medio es de 26meses (12-50). Se han evaluado los resultados clínicos, los funcionales y la satisfacción del paciente. Resultados. Los pacientes se encuentran satisfechos, obteniendo una media de 2,1 (0-3) en la escala VAS y de 16 (2-28) en el cuestionario DASH, reincorporándose a las actividades laborales en los primeros 3meses posquirúrgicos. La recuperación del arco de movilidad en comparación con la muñeca contralateral es del 96% en extensión, del 95% en flexión, del 87% en inclinación cubital y del 91% en inclinación radial. La fuerza puño media es del 95% y la fuerza de pinza, del 95%, en comparación con el lado contralateral. No han surgido complicaciones intraoperatorias ni alteraciones en la alineación carpiana posquirúrgicas. Conclusiones. La artroplastia de recubrimiento con anclaje escafoideo supone una alternativa novedosa y satisfactoria en el tratamiento de la artrosis ETT aislada. Lograr un balance adecuado entre la fuerza y la movilidad de la muñeca, sin producir una desestabilización carpiana, es importante para obtener resultados clínicos y funcionales satisfactorios (AU)


Objective. The aim of this study is to show the results of scaphotrapeziotrapezoid (STT) joint osteoarthritis treatment performing resurfacing arthroplasty with scaphoid anchorage. Material and method. An observational, descriptive and retrospective study was performed. Ten patients with isolated STT joint osteoarthritis were studied between 2013 and 2015. The mean follow-up time was 26months. Clinical results, functional and subjective scores were reviewed. Results. The patients were satisfied, achieving an average of 2.1 (0-3) on the VAS score and 16 (2 to 28) in the DASH questionnaire, and returning to work in the first three months post-surgery. Recovery of range of motion compared to the contralateral wrist was 96% in extension, 95% in flexion, 87% in ulnar deviation and 91% in radial deviation. The average handgrip strength of the wrist was 95% and pinch strength was 95% compared to the contralateral side. There were no intraoperative complications or alterations in postoperative carpal alignment. Conclusion. Resurfacing arthroplasty is proposed as a good and novel alternative in treating isolated SST joint arthritis. Achieving the correct balance between the strength and mobility of the wrist, without causing carpal destabilisation, is important to obtain satisfactory clinical and functional results (AU)

RESUMO

Objetivo. Valorar los resultados clínicos y radiológicos obtenidos en el tratamiento de la seudoartrosis de escafoides del carpo inestable en los pacientes tratados en el Hospital Clínico Universitario de Valladolid con la técnica de Fisk Fernández. Material y método. Revisión de 43 casos de seudoartrosis intervenidos quirúrgicamente mediante técnica de Fisk Fernández, con un seguimiento mínimo de 6 meses, en la que se han valorado el tiempo hasta la intervención quirúrgica, el tratamiento previo, el mecanismo de lesión, tipo de seudoartrosis y la existencia de artrosis radio-carpiana. Hemos realizado una evaluación subjetiva utilizando el cuestionario Scaphoid Score y el DASH y una valoración objetiva mediante la escala modificada de Green & O'Brien, junto con la medida de los ángulos intraescafoideos, radiolunar, escafolunar y la altura del carpo. Resultados. En nuestra serie el tiempo medio hasta consolidación fue entre 16-24 semanas, excepto en 3 pacientes que no consolidaron y precisaron cirugías de rescate. La variación entre los ángulos y la altura pre y postoperatorios del carpo medidos en las radiografías muestra que esta diferencia ha sido estadísticamente significativa. Discusión. Existen diferentes técnicas y materiales de osteosíntesis para el tratamiento de la seudoartrosis. La evaluación de resultados se realiza con escalas objetivas y subjetivas mostrando resultados variables entre estudios. Las diferentes técnicas van encaminadas a evitar la progresión de la enfermedad. Conclusión. La técnica de Fisk Fernández permite la corrección de la deformidad del escafoides, mediante injerto en cuña y la osteosíntesis con agujas de Kirschner o tornillos (AU)


Aim. The aim of the study was to evaluate the clinical and radiological results obtained in the treatment of carpal scaphoid non-union treated at the University Hospital of Valladolid using the Fisk Fernandez technique. Material and methods. A review was performed on 43 cases of surgically treated non-union using Fisk Fernandez technique with a minimum of 6 months follow-up. The time until surgery, previous treatment, the mechanism of injury, type of non-union, and the existence of radio-carpal arthrosis were evaluated. A subjective evaluation was performed using the "Scaphoid Score" and the DASH, plus an objective assessment with the modified Green & O’Brien, together with the measurement of the intra-scaphoid, radioulnar, scapholunate angles, and carpal height. Results. The median time to healing in the series was between 16 to 24 weeks, except in 3 patients who failed to heal and required salvage surgery. There was a statistically significant variation between the preoperative and postoperative angles and carpal height measured in the X-rays. Discussion. There are different osteosynthesis techniques and materials for the treatment of non-union. The evaluation of results performed using objective and subjective scales showed variable results between studies. Different techniques are aimed at preventing the progression of the disease. Conclusion. The Fisk Fernandez technique enables the deformity of the scaphoid to be corrected by wedge grafting and internal fixation with Kirschner wires or screws (AU)

RESUMO

PURPOSE: The concept of day surgery is becoming an increasingly important part of elective surgery worldwide. Relentless pressure to cut costs may constrain clinical judgment regarding the most appropriate location for a patient's surgical care. The aim of this study was to determine clinical and quality indicators relating to our experience in orthopedic day durgery, mainly in relation to unplanned overnight admission and readmission rates. Additionally, we focused on describing the main characteristics of the patients that experienced complications, and compared the patient satisfaction rates following ambulatory and non-ambulatory procedures. METHODS: We evaluated 10,032 patients who underwent surgical orthopedic procedures according to the protocols of our Ambulatory Surgery Unit. All complications that occurred were noted. A quality-of-life assessment (SF-36 test) was carried out both pre- and postoperatively. Ambulatory substitution rates and quality indicators for orthopedic procedures were also determined. RESULTS: The major complication rate was minimal, with no mortal cases, and there was a high rate of ambulatory substitution for the procedures studied. Outcomes of the SF-36 questionnaire showed significant improvement postoperatively. An unplanned overnight admission rate of 0.14 % was achieved. CONCLUSIONS: Our institution has shown that it is possible to provide good-quality ambulatory orthopedic surgery. There still appears to be the potential to increase the proportion of these procedures. Surgeons and anesthesiologists must strongly adhere to strict patient selection criteria for ambulatory orthopedic surgery in order to reduce complications in the immediate postoperative term.

RESUMO

INTRODUCTION: This project aims to study the regeneration of non-repairable lesions of peripheral nerve by muscle grafts enhanced with growth factors. MATERIAL AND METHODS: The experiment was carried out in two phases. The first one compared direct suture of a critical defect in the sciatic nerve of ten rats, with the interposition of autologous muscle graft, denatured by heat, in another ten. The second phase compared ten rats with nerve repair using an acellular muscle graft, with injection of 2cc of IGF-1 (10mg/ml mecasermin, Injectable solution) into the acellular graft of another ten. A clinical and functional follow-up was carried out including, ambulation, footprint measurement, and "grasping test". . The animals were sacrificed at 90-100 days, and samples obtained for macro- and microscopic studies with toluidine blue, haematoxylin-eosin and Masson's trichrome staining. RESULTS: The first experiment showed the characteristic findings of nerve tissue in muscle graft level sections. The second was an enhancement of the results: post-surgical clinical improvement, early ambulation, decrease in the rate of pressure ulcers in toes, recovery of the footprint, and increasing the percentage of nerve endings in distal sciatic regeneration (47-62%). CONCLUSIONS: In this study the experimental and clinical possibilities of nerve defect repair by denatured muscle are demonstrated, confirming the suitability of the technique. Furthermore, it confirms our hypothesis with clinical and cellular determinations enriched by the addition of growth factors that promote nerve regeneration.

RESUMO

Introducción. El objetivo del proyecto es estudiar la regeneración de las lesiones no reparables del nervio periférico, mediante un injerto muscular enriquecido con factores de crecimiento. Material y método. La experimentación se desarrolla en 2 fases: primero, comparamos la sutura directa del defecto crítico en el nervio ciático de 10 ratas, con la interposición de un injerto de músculo autólogo desnaturalizado por calor en otras 10. En la segunda, se comparan 10 ratas con reparación mediante injerto muscular acelular, con la inyección de 2 cc de IGF-1 (10 mg/ml de mecasermina, en solución inyectable) dentro del injerto acelular de otras 10. Realizamos el seguimiento clínico y el control funcional de la marcha, medición de la huella plantar y «Grasping Test». Fueron sacrificadas a los 90-100 días, obteniendo muestras para macro y microscopía, con tinciones de azul de toluidina, hematoxilina-eosina y tricrómico de Masson. Resultados. La primera experimentación demostró el hallazgo de tejido de características nerviosas en las secciones del injerto muscular. La segunda supuso una potenciación de los resultados: mejoría clínica posquirúrgica, precoz deambulación, descenso en la tasa de úlceras por presión en partes acras, recuperación de la huella plantar, e incremento del porcentaje de terminaciones nerviosas en regeneración del cabo distal (47-62%). Conclusiones. Exponemos en este trabajo las posibilidades experimentales y clínicas de la reparación del defecto nervioso mediante músculo desnaturalizado, confirmando la adecuación de la técnica. Además, confirmamos nuestra hipótesis con clínica y determinaciones celulares enriquecidas por la adicción de factores de crecimiento que impulsan la regeneración nerviosa (AU)

RESUMO

Objetivo: Exponer la experiencia de los autores en la realización de la técnica de microosteo síntesis percutánea con tornillos para el tratamiento de ciertas fracturas de la mano. Material y método: Se realizó un estudio prospectivo en el período comprendido entre noviembre de 2002 y noviembre de 2006 en el que 84 pacientes con fracturas en la mano se trataron mediante osteosíntesis a cielo cerrado con tornillos. La localización de la lesión fue en la base del primer metacarpiano en 12 (14,28%) ocasiones y el resto fueron fracturas de las falanges (85,71%). Todas las fracturas eran cerradas y 40 fracturas eran intraarticulares (47,61%). El tipo de fractura más frecuente fue la oblicua larga en 68 casos (80,95%). Resultado: Los resultados funcionales obtenidos tras la última revisión (6 meses) fueron excelentes en 64 pacientes (76,19%), fueron buenos en 15 pacientes (17, 86%) y fueron malos en 5 pacientes (5,95%). Conclusiones: La osteosíntesis percutánea con tornillos disminuye el tiempo de inmovilización de la fractura al mínimo, favorece una recuperación funcional más temprana y no deja defectos estéticos. Es una técnica muy útil en fracturas y en pacientes especialmente seleccionados (AU)


Purpose: To expound our experience of percutaneous screw fixation in the treatment of certain hand fractures. Materials and methods: We carried out a prospective study between November 2002 and November 2006, in which 84 patients with hand fractures were treated by means of closed screw osteosynthesis. The injury was located at the base of the first metacarpal in 12 cases (14.28%) the remainder being phalangeal fractures (85.71%). All fractures were closed, 40 of them intra-articular (47.61%). The most frequent fracture type was the long oblique fracture, which was present in 68 cases (80.95%). Results: Functional results obtained at the last follow-up visit (6 months) were excellent in 64 patients (76.19%), good in 15 (17.86%) and poor in 5 (5.95%). Conclusions: Percutaneous screw fixation sharply reduces immobilization time permitting earlier functional recovery without causing any cosmetic defects. It is a highly useful technique for carefully selected fractures and patients (AU)
