ResumoObjetivoApresentar os resultados clínico‐funcionais e a mensuração da qualidade de vida dos pacientes submetidos à artroplastia trapézio‐metacárpica.MétodoAvaliação prospectiva de 45 pacientes e 53 polegares acometidos, com diagnóstico de rizartrose idiopática submetidos à artroplastia de ressecção e interposição, com o implante Ascension®, não cimentado, de pirocarbono. Foram analisados os resultados clínico‐funcionais: análise radiográfica, o arco de movimento (ADM) em graus (°), dor (VAS: visual analogue score), qualidade de vida (Dash: disability shoulder, arm, and hand questionnaire). No grupo analisado, 38 são mulheres e sete são homens e a idade média é de 63,17 anos (50‐78). Foram operados oito pacientes com acometimento bilateral dos polegares.ResultadosApós 42,08 meses (8‐73) de seguimento, a avaliação subjetiva da dor (VAS) foi de 1,37 (1‐4). O arco do movimento completo do polegar teve um aumento de 95,75% (75‐100) do lado contralateral. O questionário Dash foi em média de 9,98 (1‐18). A taxa de complicações ou eventos negativos foi de 11,32%. Observamos cinco pacientes com luxações das próteses de polegares. Todos foram reoperados e fez‐se a capsuloplastia dorsal, com o uso como enxerto de uma porção da retinácula dos extensores, obteve‐se uma boa evolução clínica nesses casos. Um paciente apresentou fratura do metacarpo e foi tratado com osteossíntese com fio de Kirschner.ConclusãoO método é eficaz no tratamento da rizartrose de acordo com os valores apurados dos resultados clínico‐funcionais, mesmo considerando‐se as taxas de complicações. Além disso, proporciona a melhoria da qualidade de vida desses pacientes.AbstractObjectiveTo present the clinical and functional results, including measurement of quality of life, of patients undergoing trapeziometacarpal arthroplasty.MethodThis was a prospective evaluation on 45 patients (53 thumbs) with a diagnosis of idiopathic rhizarthrosis who underwent resection arthroplasty and interposition of an uncemented Ascension® implant, made of pyrocarbon. The clinical and functional results were analyzed through radiography, range of motion (ROM) in degrees (°), visual analogue scale (VAS) for pain and the disability of arm, shoulder and hand (DASH) questionnaire for quality of life. In the group analyzed, 38 were women and seven were men, and their mean age was 63.17 years (range: 50‐78). Eight patients were treated bilaterally.ResultsAfter 42.08 months of follow‐up (range: 8‐73), the subjective pain evaluation (VAS) score was 1.37 (range: 1‐4). The complete ROM of the thumb increased to 95.75% (range: 75‐100%) in relation to the contralateral side. The mean DASH questionnaire score was 9.98 (range: 1‐18). The complication rate (negative events) was 11.32%. Five patients presented dislocation of the thumb prosthesis. All of them were reoperated by means of dorsal capsuloplasty using a portion of the retinaculum of the extensors as a graft, and good clinical evolution was achieved in these cases. One patient presented fracturing of the metacarpal and was treated by means of osteosynthesis using Kirschner wires.ConclusionThis method is effective for treating rhizarthrosis, according to the measurements made on the clinical and functional results, even after taking the complication rate into consideration. Moreover, it provides an improvement of quality of life for these patients
