Early Experience of Reverse Total Shoulder Arthroplasty in a Public Hospital in Malaysia

@#Introduction: Reverse total shoulder arthroplasty provides a surgical alternative to standard total shoulder arthroplasty for the treatment of cuff tear arthropathy, arthritis and fracture sequelae. This study aimed to assess the short-term outcomes following reverse total shoulder arthroplasty for patients in a large public hospital in Malaysia. Materials and Methods: We identified and performed five primary reverse total shoulder arthroplasties between 1 May 2019 and 1 June 2020. All patients were contactable and available for analysis. Assessment of functional outcomes was performed using the Constant-Murley score, the patient satisfaction score (PSS), and imaging studies. The mean follow-up from operation to the time of reporting was 9.6 months (range, 3 to 14 months) Results: The median age for our patients was 58 years (±11.91). The most common indication for surgery was posttraumatic arthritis, followed by rotator cuff arthropathy and osteoarthritis. The mean Constant score improved from 9.0 pre-operatively to 52.3 post-operatively at a mean of 9.6 months. The majority of the patients were satisfied with the surgery as the post-operative range of motion, especially anterior elevation and abduction, improved in four of our patients and there were no short-term complications, for example, of infection or revisions, reported at the last followup. Conclusion: This study has shown that reverse total shoulder arthroplasty can yield good short-term outcomes for the treatment of complex shoulder problems in addition to cuff tear arthropathy. It should be considered a treatment for rotator cuff tears, severe arthritis and ≥ 3 parts proximal humeral fractures.

Reverse shoulder arthroplasty: Functional results in rotator cuff arthropathy / Artroplastia reversa de ombro: Resultados funcionais na artropatia do manguito

Abstract Objective To evaluate the functional results of patients submitted to reverse shoulder arthroplasty for the treatment of rotator cuff arthropathy refractory to conservative treatment. Methods A retrospective study of 20 patients (21 shoulders), 17 women (81%) and 3 men (19%), underwent a reverse shoulder arthroplasty between October 2012 and September 2017, for a rotator cuff arthropathy treatment, operated by a single surgeon in a single center. The patients were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) score, the Short-Form (36) Health Survey (SF-36), the visual analogue scale (VAS) of pain rating, and the University of California - Los Angeles (UCLA) score. The mean age at surgery was of 66 years old (range: 55 to 83 years old). The duration of symptoms before surgery was of ∼ 2.5 years (range: 12 months to 6 years). The mean follow-up was of 42.4 months (range: 19 to 56.7 months). Results The mean postoperative scores were 18.2 points in DASH; 2 points in EVA, of which 16 (77%) corresponded to mild pain, 4 (18%) to moderate pain, and 1 (5%) to severe pain; 29 points in UCLA, of which 6 patients presented a regular result (28%), 10 patients a good result (48%), and 5 patients an excellent result (24%); and 63 points in the SF-36. The complications were four cases of notching, one case of acromial fracture due to stress, and one case of postoperative infection. Conclusions Reverse arthroplasty of the shoulder presents good functional results in the evaluated scores, providing a significant improvement in the quality of life of the patients.

Resumo Objetivo Avaliar os resultados funcionais dos pacientes submetidos a artroplastia reversa de ombro, para tratamento da artropatia do manguito refratária a tratamento conservador. Métodos Estudo retrospectivo de 20 pacientes (21 ombros), 17 mulheres (81%) e 3 homens (19%), submetidos a artroplastia reversa de ombro no período de outubro de 2012 a setembro de 2017, para tratamento de artropatia de manguito rotador, operados por um único cirurgião em um único centro. Os pacientes foram avaliados pelo escore de disfunções do braço, ombro e mão (DASH, na sigla em inglês), pelo questionário genérico de avaliação de qualidade de vida SF-36 (SF-36), pela escala visual analógica de dor (EVA) e pelo escore da Universidade de Los Angeles - Califórnia (UCLA, na sigla em inglês). A média de idade na cirurgia foi de 66 anos (variação de 55 a 83 anos). O tempo de sintomas antes da realização da cirurgia foi de ∼ 2,5 anos (variação de 12 meses a 6 anos). O seguimento médio foi de 42,4 meses (variação de 19 a 56,7 meses). Resultados A média dos escores pós-operatórios foi de 18,2 pontos no DASH; de 2 pontos na EVA, sendo 16 (77%) de dores leves, 4 (18%) de dores moderadas e 1 (5%) de dor intensa; de 29 pontos no UCLA, sendo 6 pacientes com resultado regular (28%), 10 pacientes com resultado bom (48%), e 5 pacientes com resultado excelente (24%); e de 63 pontos no SF-36. Tivemos como complicações quatro casos de notching, um caso de fratura de acrômio por estresse, e um caso de infecção pós-operatória. Conclusões A artroplastia reversa do ombro apresenta bons resultados funcionais nos escores avaliados, propiciando melhora significativa na qualidade de vida dos pacientes.

Superior Capsular Reconstruction with Fascia Lata Allograft for Irreparable Supraspinatus Tendon Tears / Reconstrução da cápsula superior com Aloenxerto de fáscia lata para Roturas irreparáveis do tendão do músculo supraespinal

Abstract Superior capsular reconstruction is a recently described procedure for the treatment of irreparable supraspinatus tendon tears. Graft options that have been previously described include autogenous fascia lata and decellularized dermal graft. No studies were published with the use of fascia lata allograft. The purpose of this technical note is to describe the surgical technique of superior capsular reconstruction using fascia lata allograft. The procedure is performed by arthroscopic visualization, with the patient positioned in the lateral decubitus position. The authors describe a technique based on the use of a double-pulley knot in the glenoid and greater tuberosity, facilitating the procedure and allowing the graft to be brought into the subacromial space in the definitive position, with the appropriate tension. The allografts are available from this institution's tissue bank, cryopreserved and submitted to microbiological and histopathological evaluation. Superior capsular reconstruction is a promising surgery. The technique described in the present technical note shows a viable arthroscopic alternative, with a smaller number of anchors when compared with other techniques.

Resumo A reconstrução da cápsula superior é um procedimento descrito recentemente para o tratamento das roturas irreparáveis do tendão do músculo supraespinal. Como opções de enxerto podemos citar o uso de fáscia lata autógena e enxerto dermal acelularizado. Nenhum estudo foi publicado com o uso de aloenxerto de fáscia lata. O objetivo desta nota é descrever a técnica cirúrgica da reconstrução da cápsula superior com aloenxerto de fáscia lata. O procedimento é feito por visão artroscópica, com o paciente posicionado em decúbito lateral. Os autores descrevem uma técnica baseada no uso do nó em dupla polia na glenoide e no tubérculo maior, que facilita o procedimento e permite que o enxerto seja levado para o espaço subacromial na posição definitiva e com a tensão adequada. Os aloenxertos usados são provenientes de banco de tecidos, onde são criopreservados e submetidos à avaliação microbiológica e histopatológica. A reconstrução da cápsula superior é uma cirurgia promissora. A técnica descrita mostra uma opção artroscópica viável, com uso de menor número de âncoras quando comparada com as demais descrições.

Isolated Musculocutaneous Nerve Palsy after the Reverse Total Shoulder Arthroplasty

Reverse total shoulder arthroplasty has been performed with promising results in rotator cuff tear arthropathy. However, the global complication of the reverse total shoulder arthroplasty is relatively higher than that of the conventional total shoulder arthroplasty. Neurologic complications after reverse total shoulder arthroplasty are rare but there are sometimes remaining sequelae. The cause of the neurologic complication is multifactorial, including arm traction, position and the design of the implant. Most cases of neurologic palsy following reverse total shoulder arthroplasty occur in the axillary nerve and the radial nerve. The authors report on a case of a 71-year-old man with isolated musculocutaneous nerve palsy after reveres total shoulder arthroplasty with related literature.
