“…They fall into three categories: full constrained with hinges (constrained) [7][8][9], partially constrained (semi-constrained) [10,11] and not constrained (non-constrained) [12][13][14][15][16][17]. In the constrained type, the areas of the component fixed to the bones tend to bear a great stress and eventually succumb to breakage or loosening [18].…”

Abstract--We have followed up the results of total elbow arthroplasties on 36 elbows in 28 patients using a prosthesis newly designed in our department. The characteristics of this elbow joint (NR type) were: none constrained type, minimum bone resection and adapting each elbow joint size. The results were compared before and after operations on the basis of the Elbow Evaluation Sheet prepared by the Japanese Orthopaedic Association. The usefulness of the new prosthesis is evaluated and the problems involved are discussed. Seven years and 8 months on average (from 3 years 6 months to 13 year 9 months) after the operation, relief of pain and an increase in the flexion angle were particularly remarkable. As compared with the preoperative conditions, the activities of daily living of patients were improved, especially washing their faces, buttoning-up their shirts and eating food with greater ease. The most frequent complication was restriction to extension, which developed in 12 elbows (33%). Postoperative infection was seen in two joints of two patients (5.5%), fall out the ulnar component due to fracture of olecranon in one (2.8%) and dislocation of the elbow joint in another (2.8%). The survival rate of this elbow joint was 90% at an average 7 years and 8 months follow-up. This new elbow joint has good durability and is very useful in improving the function of the elbow joint destroyed by rheumatoid arthritis.

“…10 Comparative studies between the different available implants seem to use non validated outcome measures what makes comparison difficult and results potentially unreliable. [11][12][13][14][15][16] There ś a demand to clarify the long-term performance of TEA in selected patient groups in order to throw more light on the relative roles of the available implants.…”

RESUMOIntrodução: Na maioria dos centros a experiência com a artroplastia total do cotovelo é escassa, parecendo existir taxas significativas de complicações associadas. A maioria dos estudos realizados até à data baseia-se em scores não validades e em resultados a curto prazo. Material e Métodos: Selecionamos doentes submetidos a artroplastia total do cotovelo, com uma amostra resultante de treze artroplastias, recorrendo ao mesmo tipo de prótese -não restritiva, de baixa demanda física, com seguimento médio pós-operatório de 72 meses. Aplicamos o score de Mayo e efetuamos um estudo radiográfico pré operatoriamente e durante o período de seguimento. Resultados: Todos os doentes possuem uma patologia inflamatória sistémica. O score de Mayo médio evoluiu de 43 pontos pré-operatoriamente para 70 e 80 pontos no período de seguimento intermédio (em média 15 meses após a artroplastia) e no momento da última avaliação (em média 72 meses após a artroplastia) respetivamente. Registamos um aumento na amplitude de movimentos em todos os casos. Registamos um caso de falência mecânica e dois de neuropatia cubital transitória. Discussão: A disfunção do cotovelo acarreta grande perda na qualidade de vida do doente, incapacitando-o para atividades simples da sua vida diária. Pequenas melhorias na amplitude de movimentos e alívio da dor resultam em alterações significativas na capacidade funcional. Este estude surgiu da necessidade de esclarecer o resultado dos implantes existentes nos diferentes grupos populacionais. Conclusão: Bons resultados no alívio da dor e na capacidade funcional são obtidos a longo prazo com a artroplastia total do cotovelo não restritiva, que assim demonstra ser uma excelente opção terapêutica nos doentes de baixa demanda física com artropatia do cotovelo, nomeadamente na artrite reumatoide, condição comum e limitante na nossa população.

ABSTRACT Introduction:Experience with total elbow arthroplasty is scarce in most centers. It seems to have a significant rate of associated complications. Most studies are based on non-validated outcome measures and short-term results. Material and Methods:We selected patients undergoing unlinked total elbow arthroplasty, with a resultant sample of thirteen cases, with a mean postoperative follow-up of 72 months. We applied the Mayo Elbow Score and all patients underwent an X-ray study, prior to surgery and during the follow-up period.Results: All patients have a systemic inflammatory condition. The mean Mayo score increased from 43 points preoperatively to 70 and 80 points at the intermediate follow-up period (with a mean of 15 months after the operation) and at the time of the latest follow-up evaluation (with a mean of 72 months after the operation). There was an increase in range of motion in all cases. There was one case of mechanical failure and two cases of transient ulnar neuropathy. Discussion: Elbow dysfunction causes great loss in patient´s qual...

“…9,15,21,28 This can be attributed in part to advances in design of the implant components; 12,27,28,35 however, implant-related complications and early revision surgery continue to be problematic. 5,15,18,35 One of the many possible causes of loosening of hinged elbow prostheses could be improper positioning of the implant's articulating axis.…”
