Spinopelvic fixation (SPF) is an effective treatment method for vertically unstable pelvic ring fractures with spinopelvic dissociations (Patel et al., 2022). A heavy container fell on a 35-year-old man who was trapped and sustained injuries. His pelvic ring fracture dislocation was identified as AO Classification 61-C2.3 with rotational and vertical unstable pelvic ring; thus, crab-shaped fixation (SPF modification) was performed (Okuda et al., 2019). The pelvic fracture was fused, and the clinical outcome was good with modified Majeed score of 96. However, set-screw loosening was observed during the postoperative course. Reports of implant failures in SPF for unstable pelvic ring fractures commonly occur. However, only a few reports have demonstrated implant failure of crab-shaped fixation. Written informed consent was obtained from the patient for publication of this case report and accompanying images.
脊柱骨盆固定术（SPF）是治疗伴有脊柱骨盆分离的垂直不稳定骨盆环骨折的一种有效方法（帕特尔等人，2022年）。一个重型容器砸在一名35岁男子身上，他被困并受伤。其骨盆环骨折脱位被确定为AO分类61-C2.3型，伴有旋转和垂直不稳定的骨盆环；因此，实施了蟹形固定术（SPF改良术）（奥田等人，2019年）。骨盆骨折得到融合，临床结果良好，改良马吉德评分为96分。然而，在术后过程中观察到固定螺钉松动。关于不稳定骨盆环骨折的SPF植入失败的报道很常见。然而，仅有少数报道显示蟹形固定术的植入失败。已获得患者的书面知情同意，以发表本病例报告及附带图像。
