在反向全肩关节置换术（RTSA）中，张力错误可能导致不稳定和骨折。为了帮助理解张力，我们测量了RTSA期间术中肩关节接触力（GHCF）。26名患者接受了RTSA，并将应变计连接到底板上，以及一个试验的关节球。在被动中立、屈曲、外展、脱位和外旋（ER）时测量GHCF。5例患者因钢丝问题被排除。平均年龄70岁（54 ~ 84岁），平均身高169.5 cm(154.9 ~ 182.9)，平均体重82.7 kg（45.4 ~ 129.3）。其中雌株11株，雄株10株，42 mm球13株，38 mm球8株。平均GHCF值为中性态135 N， ER态123 N，屈曲态165 N，直立态110 N，外展态205 N。末端外展的平均力显著大于末端内质网和截骨（p < 0.05）。这些发现有助于减少不适当的张力。
Instability and fractures may result from tensioning errors during reverse total shoulder arthroplasty (RTSA). To help understand tension, we measured intraoperative glenohumeral contact forces (GHCF) during RTSA. Twenty-six patients underwent RTSA, and a strain gauge was attached to a baseplate, along with a trial glenosphere. GHCF were measured in passive neutral, flexion, abduction, scaption, and external rotation (ER). Five patients were excluded due to wire issues. The average age was 70 (range, 54–84), the average height was 169.5 cm (range, 154.9–182.9), and the average weight was 82.7 kg (range, 45.4–129.3). There were 11 females and 10 males, and thirteen 42 mm and 8 38 mm glenospheres. The mean GHCF values were 135 N at neutral, 123 N at ER, 165 N in flexion, 110 N in scaption, and 205 N in abduction. The mean force at terminal abduction is significantly greater than at terminal ER and scaption (p < 0.05). These findings could help reduce inappropriate tensioning.
