Artrodesis de la articulación Interfalángica proximal del 4.° y 5.° dedo utilizando un dispositivo de tornillos entrelazados a compresión en el trata…

2018

Resumen Objetivo Valorar el resultado radiologico y funcional de la artrodesis de la articulacion IFP del 4.° o 5.° dedo de la mano mediante el sistema intramedular de tornillos entrelazados a compresion APEX™ (Extremity Medical, Parsippany, NJ) en pacientes afectos de recidiva grave de la enfermedad de Dupuytren. Material y metodo Los resultados clinicos se valoraron mediante el cuestionario DASH y la escala EVA. En las radiografias se evaluo el angulo de artrodesis, el tiempo de fusion osea y la fijacion del implante. Se observo cualquier complicacion encontrada durante la cirugia o en el periodo de seguimiento. Resultados La muestra estuvo representada por 6 pacientes. El seguimiento med…

Efectos de una técnica manual de tracción vertebral sobre el patrón de movimiento lumbo-pélvico y activación del erector espinal durante la flexo-ext…

Resumen Objetivo Determinar el comportamiento del erector espinal y de los patrones de movimiento lumbo-pelvico durante el movimiento de flexo-extension del tronco, tras la aplicacion de una tecnica manual de descompresion lumbo-sacra, en pacientes con dolor lumbar. Material y metodos En el estudio participaron 10 sujetos con dolor lumbar inespecifico a los que se les realizaron registros electromiograficos de superficie de la actividad de la musculatura erectora espinal lumbar (L3 y L5, bilateral) y registros de la movilidad lumbo-pelvica durante la flexo-extension de tronco. Estos registros se realizaron antes y despues de la aplicacion de la tecnica. Resultados Tras comparar los resultad…

Influence of the metaphysis positioning in a new reverse shoulder prosthesis

2016

Aim of this work is to investigate the behaviour of a new reverse shoulder prosthesis, characterized by a humeral metaphysis with a variable offset, designed to increase the range of movements and to reduce the impingement. In particular, by means of virtual prototypes of the prosthesis, different offset values of the humeral metaphysis have been analysed in order to find the best positioning able to maximize the range of movements of the shoulder joint. The abduction force of the deltoid, at different offset values, has been also estimated. The study has been organized as follows. In the first step, the point clouds of the surfaces of the different components of the prosthesis have been ac…

Ultrasonographic Measurements of the Achilles Tendon in Elderly Athletes and Sedentary Men

1994

Ultrasonography was performed on the Achilles tendon of the dominant limb of 18 male elderly athletes and 11 sedentary men, aged 70 to 80 years. The tendons were examined with a real-time linear array scanner using a 7.5 MHz transducer. Both longitudinal and transverse images were taken. The mean width of the Achilles tendon was significantly larger in the athletes than in the control subjects. The tendon thickness and cross-sectional area did not differ significantly between the groups, but the figures may indicate a tendency for larger cross-sectional area in the athletes. The results suggest tendon hypertrophy following long-term training.

Foam rolling is thought to improve muscular performance and flexibility as well as to alleviate muscle fatigue and soreness. For this reason, foam rolling has become a popular intervention in all kinds of sport settings used to increase the efficiency of training or competition preparation as well as to speed post-exercise recovery. The objective of this meta-analysis was to compare the effects of foam rolling applied before (pre-rolling as a warm-up activity) and after (post-rolling as a recovery strategy) exercise on sprint, jump, and strength performance as well as on flexibility and muscle pain outcomes and to identify whether self-massage with a foam roller or a roller massager is more…

The structural validity of the Finnish version of the Disabilities of the Arm, Shoulder and Hand: A Rasch model analysis

2020

Introduction The construct validity of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) has previously been questioned. The purpose of this study was to evaluate the measurement properties of the Finnish version of the DASH for assessing disability in patients with hand complaints using Rasch Measurement Theory. Methods A cohort of 193 patients with typical hand and wrist complaints were recruited at a surgery outpatient clinic. The DASH scores were analysed using the Rasch model for differential item functioning, unidimensionality, fit statistics, item residual correlation, coverage/targeting and reliability. Results In the original DASH questionnaire, the item response …

Clinical Outcomes After Aggressive Active Early Motion and Modified Kleinert Regimens: Comparison of 2 Consecutive Cohorts

2021

Background Modern multistrand repairs can withstand forces present in active flexion exercises, and this may improve the outcomes of flexor tendon repairs. We developed a simple home-based exercise regimen with free wrist and intrinsic minus splint aimed at facilitating the gliding of the flexor tendons and compared the outcomes with the modified Kleinert regimen used previously in the same institution. Methods We searched the hospital database to identify flexor tendon repair performed before and after the new regimen was implemented and invited all patients to participate. The primary outcome was total active range of motion, and secondary outcomes were Disabilities of Arm, Shoulder, and …

Can hip resurfacing be safely revised with short-stem total hip arthroplasty? A case series of six patients.

2021

Abstract Background The usage of short stems in primary total hip arthroplasty (THA) has constantly gained popularity over the last decade, however, to date, short stems are not eligible to be used as revision implants. The aim of this study was to retrospectively evaluate the outcome of revision surgery of failed hip resurfacing arthroplasty (HRA) using short-stem THA. Methods In a single center, retrospective analysis, 6 consecutive patients who were treated with a calcar-guided short stem after failure of HRA were evaluated. The mean follow-up was 3.25 years (SD 0.45). Patient reported outcome measurements (PROMs) were recorded using the Harris hip score (HHS) and The Western Ontario and…
