Periprosthetic joint infection of shoulder arthroplasties is one of the most frequent reasons for pain and revision surgery of shoulder arthroplasties. Propionibacterium acnes is one of the commonest microorganisms causing periprosthetic joint infection in shoulder arthroplasties. It is difficult to detect this slow growing microorganism. This paper gives an overview of the different diagnostic methods. A combination of unspecific and specific tests (detection of microorganism and sensitivity to antibiotics) is helpful in identifying a periprosthetic shoulder infection. Aspiration of the joint can combine different unspecific and specific tests. In patients with punctio sicca and suspected periprosthetic joint infection, we recommend biopsy of periprosthetic tissue.
肩关节置换术后假体周围感染是肩关节置换术疼痛和翻修手术最常见的原因之一。痤疮丙酸杆菌是肩关节置换术后假体周围感染最常见的微生物之一。检测这种生长缓慢的微生物很困难。本文概述了不同的诊断方法。非特异性和特异性检测（微生物检测及对抗生素的敏感性）相结合有助于识别假体周围肩关节感染。关节穿刺可联合不同的非特异性和特异性检测。对于穿刺干燥且怀疑假体周围关节感染的患者，我们建议对假体周围组织进行活检。
