RESUMO

Objective The objective of the present study is to evaluate the restoration capacity of the hip anatomic rotation center with the use of acetabular tantalum cups, associated or not with addition wedges. Methods Retrospective analysis of patients undergoing hip arthroplasty revision using tantalum between June 2013 and April 2017. The abduction angle of the acetabular component and the horizontal and vertical distances of the component to the center of anatomical rotation of the hip were evaluated. The measurements were made through baseline radiographs performed in the preoperative period and at the last follow-up visit. Results A sample of 21 patients was obtained, 11 (52%) men and 10 (48%) women, with a mean age of 62 ± 13 years old. The mean abduction angle of the acetabular cup decreased from 48.76° ± 13.88 ° in the preoperative period to 38.52° ± 10.08 ° in the postoperative period, and this difference was statistically significant ( p = 0.001). The distances from the center of rotation of the prosthesis relative to the center of anatomical rotation of the hip were also lower after revision surgery with tantalum. The mean horizontal distance of 12.74 ± 10.59 mm was reduced to 7.11 ± 4.84 mm, and the mean vertical distance was reduced from 14.79 ± 10.05 mm to 4.89 ± 6.21 mm, and these reductions were statistically significant ( p < 0.001). Conclusion Hip arthroplasty revision with tantalum cups, associated or not with addition wedges, significantly recovered the anatomical rotation center of the hip.

Resumo Objetivo O objetivo do presente estudo é avaliar a capacidade de restauração do centro de rotação anatômico do quadril com uso de copas acetabulares de tântalo associado ou não a cunhas de adição. Métodos Análise retrospectiva dos pacientes submetidos a revisão de artroplastia do quadril comuso de tântalo entre o período de junho de 2013 e abril de 2017. Foramavaliados o ângulo de abdução do componente acetabular e as distâncias horizontal e vertical do componenteao centro de rotação anatômicodoquadril.Asmedidas foramrealizadas através de radiografias da bacia realizadas no pré-operatório e na última visita de seguimento. Resultados Obteve-se uma amostra de 21 pacientes, 11 (52%) homens e 10 (48%) mulheres, com média de idade de 62 ± 13 anos. O ângulo médio de abdução da copa acetabular reduziu de 48,76° ± 13,88° no pré-operatório para 38,52° ± 10,08° no pósoperatório, sendo esta diferença estatisticamente significativa (p = 0,001). As distâncias do centro de rotação da prótese em relação ao centro de rotação anatômico do quadril também foram menores após a cirurgia de revisão com o tântalo. A distância média horizontal de 12,74 ± 10,59 mm foi reduzida para 7,11 ± 4,84 mm, e a distância média vertical foi reduzida de 14,79 ± 10,05 mm para 4,89 ± 6,21 mm, sendo essas reduções estatisticamente significativas (p < 0,001). Conclusão As revisões de artroplastia do quadril comcopas de tântalo, associadas ou não a cunhas de adição, recuperaram de forma significativa o centro de rotação anatômico do quadril.

RESUMO

PURPOSE: To evaluate the primary clinical outcomes of arthroscopic labral repair. METHODS: All patients who underwent arthroscopic repair of the acetabular labrum performed by a senior surgeon between October 2010 and December 2013 were invited to participate in this prospective study. Patients included were those who had a preoperative diagnosis of labral tears, a lateral centre edge greater than 25° and a labral tear believed to be suturable during the intraoperative evaluation. Patients with Tönnis grade 2 or grade 3 hip osteoarthritis and those who had undergone a previous hip surgery were excluded. All patients were evaluated using the modified Harris Hip Score (mHHS) during the final appointment before surgery, 4 months after surgery and at the final evaluation. Interviews were conducted by the senior surgeon. RESULTS: Eighty-four patients (90 hips) underwent arthroscopic repair. The mean age was 44.2 years and the mean follow-up period was 43.0 months (minimum of 25 months and maximum of 59 months). The mean mHHS was 80.4 preoperatively, 95.0 at 4 months postoperatively and 96.6 at final evaluation. A statistically significant difference existed among these scores (p<0.001). CONCLUSION: Arthroscopic labral repair was associated with a clinically significant improvement in mHHS after short-term (4 months) and medium-term (43 months) follow-up. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

RESUMO

OBJECTIVE: To propose a multidisciplinary protocol to standardize the care of patients undergoing total hip arthroplasty (THA) and evaluate it effectiveness after implementation. METHODS: Retrospective evaluation of 95 consecutive patients undergoing THA divided into two groups, one group of 47 patients operated before the protocol implementation and 48 after. RESULTS: Assessing the re-admission rate, among 47 patients evaluated prior to implementation of the protocol, seven (14.9%) were re-admitted, and when observing the 48 patients evaluated after implementation, one (2.1%) was re-admitted, showing statistical significance (p < 0.05). The chance of re-admission before the protocol was eight times the chance of hospitalization after implementation (95% CI: 1.01 to 377.7). By comparing the clinical complications among the groups, it was observed that there was a lower rate of complications following implementation of the protocol (p = 0.006). CONCLUSION: The introduction of a multidisciplinary protocol to standardize the management of patients undergoing THA decreased the rates of rehospitalization and clinical complications after the procedure.

OBJETIVO: Propor um protocolo multidisciplinar para padronização do cuidado dos pacientes que serão submetidos a artroplastia total do quadril (ATQ) e avaliar sua eficácia após a implantação. MÉTODOS: Avaliação retrospectiva dos resultados de 95 pacientes consecutivos submetidos a ATQ divididos em dois grupos, um com 47 operados antes da implantação do protocolo e 48 após. RESULTADOS: Na avaliação da taxa de reinternação, tem-se que entre os 47 pacientes avaliados antes da implantação do protocolo, sete (14,9%) foram reinternados e dos 48 avaliados depois da implantação, um (2,1%) foi reinternado, mostrou-se significância estatística (p < 0,05). A chance de reinternação antes da implantação foi oito vezes maior do que a chance de internação após a implantação (IC 95%: 1,01 a 377,7). Ao comparar as complicações clínicas entre os grupos observou-se que houve menor taxa de complicações após a implantação do protocolo (p = 0,006). CONCLUSÃO: A introdução de um protocolo multidisciplinar para padronização do manejo do paciente submetido a ATQ diminuiu as taxas de reinternação e de complicações clínicas após o procedimento.
