Increased fatigue of the biceps after tenotomy of the long head of biceps tendon

Effect of age, gender, and body mass index on incidence and satisfaction of a Popeye deformity following biceps tenotomy or tenodesis: secondary analysis of a randomized clinical trial

BACKGROUND

The purpose of this study was to determine the incidence of Popeye deformity following biceps tenotomy vs. tenodesis and evaluate risk factors and subjective and objective outcomes.

METHODS

Data for this study were collected as part of a randomized clinical trial in which patients aged ≥18 years undergoing arthroscopic shoulder surgery for a long head of the biceps tendon lesion were allocated to undergo tenotomy or tenodesis. The primary outcome measure for this secondary analysis was rate of Popeye deformity at 24 months postoperation as determined by an evaluator blinded to group allocation. Those with a deformity indicated their satisfaction with the appearance of their arm on a 10-cm visual analog scale, rated their pain and cramping, and completed the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form and the Western Ontario Rotator Cuff index. Isometric elbow flexion and supination strength were also measured. Cohen kappa was calculated to measure inter-rater reliability between patient and evaluator on the presence of a deformity. Logistic regression was performed to identify predictors of presence or absence of a Popeye deformity.

RESULTS

One hundred fourteen patients were randomly assigned to 2 groups, of which 42 to the tenodesis group and 45 to the tenotomy group completed a 24-month follow-up. Based on clinical observation, the odds of a Popeye in the tenotomy group were 4.3 times greater than in the tenodesis group (P = .018) with incidence of 33% (15/45) and 9.5% (4/42), respectively. Surgical technique was the only significant predictor of perceived deformity, with male gender trending toward significance (odds ratio 7.33, 95% confidence interval 0.867-61.906, P = .067). Mean (standard deviation) satisfaction score of those with a deformity regarding appearance of their arm was 7.3 (2.6). Increasing satisfaction was correlated with increasing age (r = 0.640, P = .025), but there was no association with gender (r = -0.155, P = .527) or body mass index (r = -0.221, P = .057). Differences in subjective outcomes were dependent on whether the Popeye was clinician- or self-assessed.

CONCLUSION

The odds of developing a perceived Popeye deformity was 4.3 higher after tenotomy compared to tenodesis based on clinician observation. Male gender was trending toward being predictive of having a deformity. Pain and cramping were increased in those with a self-reported Popeye. Younger patients were significantly less satisfied with a deformity despite no difference in functional outcomes at 24 months. Thus, biceps tenodesis may be favored in younger male patients to minimize the risk of Popeye and the risk of dissatisfaction in the appearance of their arm following surgery.

A acetabularização como fator protetor na artropatia do manguito rotador

Objetivo Verificar se os ombros com acetabularização têm melhores resultados funcionais nos casos de artropatia do manguito rotador.

Métodos Avaliação transversal clínica e radiológica de 65 ombros com artropatia do manguito rotador por meio da mensuração da amplitude de movimento (ADM) do ombro, do escore de Constant-Murley, e das classificações radiológicas de Hamada e Seebauer. Os achados clínicos foram comparados com os radiográficos.

Resultados Segundo a classificação de Seebauer, com relação à ADM, observamos melhores resultados nos tipos A. Houve diferença estatística significativa na elevação anterior, e rotação medial entre os tipos A e B (p < 0.05). A rotação lateral não demonstrou diferença estatística significativa entre os tipos A e B. O escore de Constant-Murley apresentou melhores resultados nos tipos A, e houve diferença estatística significativa entre os grupos A e B (p < 0,05). Segundo a classificação de Hamada, observamos que a ADM teve melhores resultados nos tipos 3, 2 e 1, e houve diferença estatística significativa para a elevação anterior e a rotação medial (p < 0,05) quando comparadas com os grupos 4A, 4B e 5. Não houve diferença estatística significativa entre os grupos de Hamada em relação à rotação lateral. Ainda segundo Hamada, o escore de Constant-Murley apresentou melhores resultados nos tipos 3, 1 e 2, e houve diferença estatística significativa entre os grupos 3 e 5.

Conclusão A ADM e a função do ombro apresentavam-se melhores nos pacientes com acetabularização (Seebauer 1A e Hamada 3), e piores naqueles com artrose glenoumeral (Seebauer 1B, 2B e Hamada 4A, 4B e 5).

Intra-articular arthroscopic biceps tenodesis with interference screw: clinical and isokinetic evaluation

Background

Although biceps tenodesis has been widely used to treat its pathologies, few studies looked at the objective evaluation of elbow strength after this procedure. The purpose of this study is to clinically evaluate patients submitted to long head of the biceps (LHB) tenodesis with interference screws through an intra-articular approach and analyze the results of an isokinetic test to measure elbow flexion and forearm supination strengths.

Methods

Patients who had biceps tenodesis were included in the study if they had a minimum follow-up of 24 months. Patients were excluded if they had concomitant irreparable cuff tears or previous or current contralateral shoulder pain or weakness. Postoperative evaluation was based on University of California-Los Angeles (UCLA) shoulder score and on measurements of elbow flexion and supination strength, using an isokinetic dynamometer. Tests were conducted in both arms, with velocity set at 60º/s with 5 concentric-concentric repetitions.

Results

Thirty-three patients were included and the most common concomitant diagnosis were rotator cuff tear (69%) and superior labrum anterior to posterior (SLAP) lesions (28%). The average UCLA score improved from 15.1 preoperatively to 31.9 in the final follow-up (P < .001). Isokinetic tests showed no difference in peak torque between the upper limbs. One patient had residual pain in the biceps groove. None of the patients had Popeye deformity. UCLA score and follow-up length did not demonstrate correlation with peak torque.

Conclusion

Arthroscopic proximal biceps tenodesis with interference screw, close to the articular margin, yielded good clinical results. Isokinetic tests revealed no difference to the contralateral side in peak torque for both supination and elbow flexion.
