Functional and radiographic evaluation and quality of life analysis after cementless total hip arthroplasty with ceramic bearings: minimum of 5 years follow-up.

OBJECTIVE: The aim of the study is to analyze and correlate functional and radiographic results and quality of life in patients undergoing cementless total hip arthroplasty with ceramic surface, performed at Hospital Servidor Publico de Sao Paulo from 2001 to 2006. METHODS: We retrospectively analyzed 35 hips treated with cementless total hip arthroplasty with ceramic surfaces with a minimum follow-up of 5 years. Functional evaluation was based on the Harris Hip Score (HHS). Radiographic evaluation was based on the method proposed by Charles Engh for evaluation of femoral osseointegration and on DeLee and Charnley zones for acetabulum. Quality of life was assessed by SF-36 questionnaire. RESULTS: The HHS presented excellent and good results in 91% of patients postoperatively (mean of 93.14 points HHS). As for radiographic evaluation, we found excellent results in 100% of evaluated hips (proven osseointegration). SF-36 scores were not compared to the control group for the following components: pain, vitality, mental health and social aspects. The difference between HHS pre and postoperatively had a statistically significant correlation with physical functioning of the SF-36. CONCLUSION: Total hip arthroplasty with ceramic surface is a treatment that enables functional improvement of the hip and increases quality of life of patients to levels close to those of people without joint diseases.

OBJETIVO: Analisar e correlacionar os resultados funcionais e radiográficos e o grau de qualidade de vida em pacientes submetidos a artroplastia total de quadril não cimentada com superfície em cerâmica feita no Hospital Servidor Público Estadual de 2001 a 2006. MÉTODOS: Fizemos um estudo retrospectivo que analisou 35 quadris tratados com artroplastia total do quadril não cimentada com superfície em cerâmica, com tempo de seguimento mínimo de cinco anos. A avaliação funcional baseou-se no questionário de Harris Hip Score (HHS), a avaliação radiográfica baseou-se no método proposto por Charles Engh para o fêmur e sinais de integração óssea nas zonas de DeLee e Charnley para o acetábulo e a avaliação da qualidade vida baseou-se no questionário SF-36 (Medical Outcomes 36 Item Short-Form Health Survey). RESULTADOS: O questionário HHS apresentou resultados considerados como excelentes e bons em 91% dos pacientes no pós-operatório (média de 93,14 pontos HHS). Quanto à avaliação radiográfica, em 100% dos quadris operados tivemos osteointegração óssea comprovada. Os escores do SF-36 não foram estatisticamente significantes em relação ao grupo controle para os seguintes componentes: dor, vitalidade, aspectos sociais e saúde mental. A variação entre o HHS pré e pós-operatório se correlaciona com a capacidade funcional no SF-36. CONCLUSÃO: A artroplastia total com superfície de cerâmica é uma operação que possibilita a melhoria funcional do quadril e o aumento da qualidade de vida do paciente para níveis próximos aos da população sem doenças da articulação.

SURGICAL TREATMENT OF DISTAL RADIUS FRACTURES WITH A VOLAR LOCKED PLATE: CORRELATION OF CLINICAL AND RADIOGRAPHIC RESULTS.

OBJECTIVES: To analyze and correlate the clinical and radiographic results from patients with distal radius fractures who underwent surgical treatment with a fixed-angle volar locked plate. METHODS: Sixty-four patients with distal radius fractures were evaluated. They all underwent surgical treatment with a volar locked plate for the distal radius, with a minimum of six months of postoperative follow-up. They underwent a physical examination that measured range of motion and grip strength, answered the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and underwent radiographic examination. RESULTS: In the physical examination on the patients, all the range-of-motion measurements were reduced. Grip strength measured in kgf was on average 85.8% of the strength on the unaffected side. The mean DASH score was 15.99. A significant relationship was found between lower DASH scores and losses of extension and grip strength. On the radiographs, the mean values in relation to the unfractured side were 84.0% for radial inclination, 85.4% for radial length and 86.8% for volar deviation of the radius. Loss of radial length was correlated with losses of extension and grip strength.
