Abstract

Objectives: Fatty atrophy and fatty infiltration have been considered as limiting factors for rotator cuff repair. The metabolic activity of the muscle can be measured noninvasively by PET. In our study, we aim to compare the metabolic activity between the shoulders with rotator cuff tears and normal shoulders.

Methods: All the patients with unilateral full-thickness rotator cuff tears were included. The patients were divided into two groups based on fatty atrophy and the metabolic activities of the rotator cuff muscles, trapezius, and deltoid were calculated using an 18 F-2-deoxy- d -glucose PET-computed tomography scan for comparison.

Results: A total of 17 patients were included. The standardized uptake values were compared between the affected shoulder and the normal shoulders. There was a significant increase in uptake in the insertion sites and musculotendinous junctions in the rotator cuff torn group. The standardized uptake values showed no significant difference between the low-grade and high-grade groups.

Conclusion: Our first hypothesis was also proven wrong; when we found that there was no statistically significant difference in the metabolic activity in muscle bellies of normal shoulders and those with rotator cuff tears. Our second hypothesis was proven wrong when found that there was no statistically significant difference in the metabolic activities of rotator cuff muscles between high-grade and low-grade fatty atrophy groups. The metabolic activities of the middle deltoid and trapezius are inversely related. Based on the findings of our study, fatty atrophy or fatty infiltration alone cannot be considered a limiting factor for rotator cuff repair.

通过 18F-2-deoxy-d-glucose PET 计算机断层扫描评估撕裂肩袖肌肉的代谢活动。
目的:脂肪萎缩和脂肪浸润一直被认为是肩袖修复的限制因素。肌肉的代谢活动可通过 PET 进行无创测量。在我们的研究中,我们旨在比较肩袖撕裂的肩部和正常肩部的代谢活动:方法:纳入所有单侧全厚肩袖撕裂患者。方法:纳入所有单侧全厚肩袖撕裂患者,根据脂肪萎缩情况将患者分为两组,并使用 18F-2 脱氧葡萄糖 PET 计算机断层扫描计算肩袖肌、斜方肌和三角肌的代谢活动,以进行比较:结果:共纳入 17 名患者。结果:共纳入 17 名患者,比较了患病肩部和正常肩部的标准化摄取值。肩袖撕裂组插入部位和肌肉肌腱连接处的摄取量明显增加。标准化摄取值显示,低级别组和高级别组之间没有明显差异:我们的第一个假设也被证明是错误的,因为我们发现正常肩部和肩袖撕裂者的肌腹代谢活动没有明显的统计学差异。我们的第二个假设也被证明是错误的,因为我们发现肩袖肌肉的代谢活动在高级别和低级别脂肪萎缩组之间没有统计学意义上的显著差异。三角肌中部和斜方肌的代谢活动成反比。根据我们的研究结果,不能将脂肪萎缩或脂肪浸润单独视为肩袖修复的限制因素。

期刊介绍: Nuclear Medicine Communications, the official journal of the British Nuclear Medicine Society, is a rapid communications journal covering nuclear medicine and molecular imaging with radionuclides, and the basic supporting sciences. As well as clinical research and commentary, manuscripts describing research on preclinical and basic sciences (radiochemistry, radiopharmacy, radiobiology, radiopharmacology, medical physics, computing and engineering, and technical and nursing professions involved in delivering nuclear medicine services) are welcomed, as the journal is intended to be of interest internationally to all members of the many medical and non-medical disciplines involved in nuclear medicine. In addition to papers reporting original studies, frankly written editorials and topical reviews are a regular feature of the journal.
