Abstract

Objectives: To evaluate CT imaging findings in symptomatic patients with and without revision surgery (RS) after reverse shoulder arthroplasty (RSA).

Materials and methods: In this retrospective study, two radiologists assessed CT imaging findings in symptomatic patients with RSA over 5 years, including material fracture and loosening of the peg, baseplate, screws, and humeral stem, screw positioning, prosthesis dislocation, glenoid notching, fractures, and deltoid muscle quality. The primary outcome parameter was RS. Patients were assigned Group 1 (RS) or Group 2 (No RS).

Results: Ninety-nine patients (mean age 70.4 ± 10.3 years, 61 females) met the inclusion criteria. Fifty-two patients (29 females) received RS after 34.0 ± 38.3 months. The only CT imaging finding significantly associated with RS was prosthesis dislocation (P = .007, odds ratio (OR) 10.95, 95% CI 1.34-89.24). All other evaluated CT imaging findings were not associated with RS. Yet, loosening of the peg (30% vs. 16%), baseplate (15% vs. 6%), and superior screw (18% vs. 7%) and periprosthetic humeral fractures (29% vs. 13%)-as common reasons for RS-were more frequent in patients with RS than in those without, however not reaching significance (P ≥ .11). The large majority of patients had glenoid notching (79% vs. 94%), irrespective of RS.

Conclusion: In this cohort of symptomatic patients after RSA, prosthesis dislocation was the only CT imaging finding associated with RS. Besides, there was a trend with higher numbers of loosening of the peg, baseplate, and superior screw, as well as periprosthetic humeral fractures in patients with RS, though not reaching significance.

逆行肩关节置换术后行和未行翻修手术的有症状患者的CT影像学表现。

目的：评价逆行肩关节置换术（RSA）后行和不行翻修手术（RS）的有症状患者的CT影像学表现。材料和方法：在这项回顾性研究中，两名放射科医生评估了5年来有症状的RSA患者的CT影像学表现，包括材料骨折、钉、基板、螺钉和肱骨干松动、螺钉定位、假体脱位、关节盂切迹、骨折和三角肌质量。主要结局参数为RS。患者被分为1组（RS）或2组（无RS）。结果：99例患者（平均年龄70.4±10.3岁，女性61例）符合纳入标准。52例患者（女性29例）术后34.0±38.3个月接受RS治疗。唯一与RS有显著相关的CT成像发现是假体脱位(P =。007，优势比（OR） 10.95, 95% CI 1.34-89.24)。所有其他评估的CT成像结果与RS无关。然而，作为RS的常见原因，螺钉松动（30%对16%）、基板松动（15%对6%）、上螺钉松动（18%对7%）和肱骨假体周围骨折（29%对13%）在RS患者中比在没有RS的患者中更常见，但没有达到显著性（P≥0.11）。结论：在RSA术后有症状的患者中，假体脱位是唯一与RS相关的CT影像学表现。此外，RS患者的假体螺钉、基板、上部螺钉松动以及假体周围肱骨骨折的数量有增加的趋势，但没有达到显著性意义。

期刊介绍： Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration. This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
