RESUMEN
Objective Clinical and functional evaluation of the surgical treatment for chronic injury of the distal biceps brachii applying a surgical technique with grafting of the distal triceps brachii tendon. Methods A study based on a review of the medical records and clinical evaluation of the patients submitted to surgical treatment for chronic injury to the distal insertion of the biceps brachii between February 2015 and February 2017. In a 12-month-minimum postoperative follow-up, 7 patients were evaluated regarding the range of motion of the operated and non-operated elbows, flexion, upper-limb extension and supination with a digital dynamometer, the hook test, the satisfaction index, and the Disabilities of the Arm, Shoulder and Hand (DASH) and Mayo Elbow Performance Score (MEPS) intruments. Results During the postoperative functional evaluation, no patient reported dissatisfaction with the esthetic outcome of the incisions, and all of them were satisfied/very satisfied with the range of motion and strength of the operated limb. No neurovascular complications, surgical site infection or tendon rupture were observed. On the MEPS and DASH scales, all patients scored 100 and 0 respectively. The mean flexion was of 133.5° on the operated side, versus 139.2° on the non-operated side. The mean extension was of 5° on the operated side versus 0° on the non-operated side. The supination was of 86.5° versus 90°, and the pronation, 80° versus 80°, when comparing the operated and non-operated sides respectively. The mean flexion, extension and supination corresponded respectively to 92.5%, 96.4% and 86.8% of those of the non-operated limb. Conclusion Recosntruction of the distal biceps brachii with triceps grafting seems to be an effective and safe option for the treatment of chronic distal biceps injuries.
RESUMEN
OBJECTIVE: To evaluate the difference between the total blood loss in patients undergoing primary total knee arthroplasty with and without the use of tourniquet. METHODS: A retrospective cohort study, with analysis of medical records of patients undergoing primary total knee arthroplasty in 2015, with and without the use of a tourniquet. Comparison was performed of hemoglobin (HB) and hematocrit (HT) variation in the complete blood count (CBC) during the pre- and post-operative period between the two groups. RESULTS: There were 117 patients undergoing primary total knee arthroplasty included, minimum age of 33 and maximum of 86 years, with a mean of 67 years. 64.1% of the surgeries used a tourniquet and 35.9% did not. The mean preoperative HB in Group 1 was 13.08 and 12.97 in Group 2 (p = 0.435). The mean postoperative HB in Group 1 was 11.64 and 10.93 in Group 2 (p = 0.016). The variation of HB in Group 1 was 1.44 and 2.04 in Group 2 (p = 0.025). The mean preoperative HT in Group 1 was 38.96 and 39.01 in Group 2 (p = 0.898). The mean postoperative HT in Group 1 was 34.47 and 32.19 in Group 2 (p = 0.005). The variation of HT in Group 1 was 4.49 and 6.82 in Group 2 (p = 0.001). A total of 21 patients received transfusions RCC (red cell concentrates), as a result of HB below 8 g/dL or clinical symptoms, respectively, representing seven of Group 1 (9.3% of total intra-group) and 14 of Group 2 (33.3% of total intra-group), with p = 0.001. CONCLUSION: In patients undergoing primary total knee arthroplasty using a tourniquet, a lower variance in the hematimetric indices was observed and fewer blood transfusions were necessary.
OBJETIVO: Avaliar a diferença entre a perda sanguínea total em pacientes submetidos à artroplastia total do joelho com e sem o uso de garrote. MÉTODOS: Estudo de coorte retrospectivo, com análise dos prontuários de pacientes submetidos a artroplastia primária total de joelho em 2015, com e sem o uso de garrote. Comparou-se a variação de hemoglobina (HB) e hematócrito (HT) no pré- e pós-operatório entre os dois grupos. RESULTADOS: Foram incluídos 117 pacientes submetidos a artroplastia total de joelho primária, idade mínima de 33 e máxima de 86 anos, com média de 67; em 64,1% das cirurgias, foi usado garrote e em 35,9%, não. No pré-operatório, a média da HB no Grupo 1 foi de 13,08; no Grupo 2, 12,97 (p = 0,435). No pós-operatório, a média da HB no Grupo 1 foi de 11,64; no Grupo 2, 10,93 (p = 0,016). A variação da HB no Grupo 1 foi de 1,44; no Grupo 2, de 2,04 (p = 0,025). No pré-operatório, a média do HT no Grupo 1 foi de 38,96; no Grupo 2, de 39,01 (p = 0898). No pós-operatório, a média do HT no Grupo 1 foi de 34,47; no Grupo 2, de 32,19 (p = 0,005). A variação do HT no Grupo 1 foi de 4,49; no Grupo 2, de 6,82 (p = 0,001). Dos pacientes, 21 receberam transfusão de CH (concentração de hemácias), por HB abaixo de 8 ou sintomas clínicos, sete do Grupo 1 (9,3% do total intragrupo) e 14 do Grupo 2 (33,3% do total intragrupo) com p = 0,001. CONCLUSÃO: Nos pacientes submetidos a artroplastia total de joelho primária com o uso de garrote, ocorreu uma menor variância dos índices hematimétricos e um menor número de transfusões sanguíneas foi necessário.
