Avaliação funcional de fratura transtrocanteriana instável do fêmur em idosos / Functional evaluation of unstable transtrochanteric fracture of the femur in elderly patients

Rigol, Julio Paim January 2011 (has links)
INTRODUÇÃO: as fraturas transtrocanterianas do fêmur são muito frequentes nos idosos, e seu tratamento é eminentemente cirúrgico. Na grande maioria dos casos há a consolidação da fratura, mas os pacientes parecem não evoluir satisfatoriamente do ponto de vista clínico. O objetivo deste estudo é avaliar a qualidade da marcha de pacientes que foram submetidos ao tratamento cirúrgico por uma técnica de fratura transtrocanteriana instável. MATERIAL E MÉTODOS: participaram deste estudo 24 pacientes operados por fratura transtrocanteriana instável do fêmur com utilização do DHS. Os pacientes foram acompanhados prospectivamente, e foi avaliada a qualidade da marcha de pós-operatório e comparada com a de antes da cirurgia, segundo o escore de Robinson. RESULTADOS: no período pré-operatório, 14 pacientes (58,3%) eram do grupo I segundo o escore de marcha de Robinson; 4 (16,7%), do grupo II; 3 (12,5%), do grupo III; 1 (4,2%), do grupo IV; e 2 (8,3%), do grupo V. Todas as fraturas evoluíram para a consolidação, e a taxa de mortalidade foi de 25%. Todos os pacientes foram encaminhados para o mesmo protocolo de reabilitação, e após um período médio de 9,69 meses, 28,6% dos pacientes apresentavam-se no grupo I do escore de Robinson; 23,8%, no grupo II; 4,8%, no grupo III; 23,8%, no grupo IV; e 19% estavam no grupo V. Esses dados mostram que, apesar da alta taxa de consolidação das fraturas, não houve melhora sequer na manutenção da qualidade da marcha dos pacientes, sendo estatisticamente significante (p= 0,003). CONCLUSÕES: as fraturas transtrocanterianas instáveis do fêmur podem ser tratadas com o DHS, apresentando uma alta taxa de consolidação. Entretanto, parecem não evoluir bem do ponto de vista funcional. Esses achados deveriam ser confirmados por outros estudos com maior número de pacientes e avaliando outro tipo de implante. / INTRODUCTION: transtrochanteric fractures of the femur are very frequent in elderly patients, and its treatment is mainly surgical. In most cases the fracture can be consolidated, but patients seem not to have a satisfactory clinical evolution. The objective of this study is to evaluate gait quality of patients who have been submitted to surgical treatment with a technique of unstable transtrochanteric fracture. MATHERIAL AND METHODS: This study evaluated 24 patients who had been operated for unstable transtrochanteric fracture of the femur with the use of DHS. The patients were prospectively followed up, and the postoperative gait quality was evaluated and compared to preoperative gait using Robinson score. RESULTS: In preoperative period, 14 (58.3%) patients belonged to Group I according to Robinson score, 4 (16.7%) belonged to Group II, 3 (12.5%) belonged to Group III, 1 (4.2%) belonged to Group IV, and 2 (8.3%) belonged to Group V. All the fracture evolved to consolidation, and the mortality rate was 25%. All the patients were referred to the same rehabilitation protocol, and after an average period of 9.69 months, 28.6% were in Group I of Robinson score, 23.8% were in Group II, 4.8% in Group III, 23.8% in Group IV, and 19% in Group V. These data show that, despite the high rate of fracture consolidation, there was no improvement even in the maintenance of the patients’ gait quality, being it statistically significant (p= 0.003). CONCLUSIONS: Unstable transtrochanteric fractures of the femur can be treated with DHS, presenting a high consolidation rate. However, they seem not to evolve functionally. These findings should be confirmed by other studies with a higher number of patients who also use another type of implant.

Exploratory Study on Lower Limb Amputee Patients : Use of IMUs to Monitor the Gait Quality During the Rehabilitation Period / Förberedande studie på patienter med amputerad nedre extremitet : Användning av IMU:er för att övervaka gångkvaliteten under rehabiliteringsperioden

Barthélemy, Aude January 2019 (has links)
Specific rehabilitation is a key period for a lower-limb amputee patient. While learning how to walk with a prosthesis, the patient needs to avoid any gait compensations that may lead to future comorbidities. To reach a gait pattern close to the one of a healthy person, objective data may be of great help to complement the experience of the clinician team. By using 6 IMUs located on the feet, shanks and thighs accompanied by 3 accelerometers on the pelvis, sternum and head, data could be recorded during walking exercises of 7 rehabilitation sessions of a patient. To compute the absolute symmetry index of the stance phase duration and the stride duration all over the instrumented sessions, the gait events defining the transitions between gait phases were determined thanks to several algorithms. By first comparing the error obtained in the calculation of the stance phase duration with all tested algorithms as compared to the data from pressure insoles considered as a reference system, the algorithm developed by Trojaniello and collaborators [1] was found to be the most adapted to this situation. Using this algorithm on the data from all sessions highlighted the possibility to detect changes in the symmetry of stance phase duration and stride duration, that are relative to the gait quality. This means that IMUs seem to be able to monitor the progress of a patient during his rehabilitation. Hence, IMUs have proven themselves to be a system of great interest in the analysis of the gait pattern of a lower-limb amputee patient in rehabilitation, by allowing for an embedded measurement of much more parameters than the pressure insoles, whose calibration constituted a real limitation.
