To assess the midterm results of closed reduction and percutaneous fixation (CRPF) with computed tomography (CT)-guided sacroiliac screw fixation in longitudinal posterior pelvic ring fractures. To document radiographic and CT follow-up patterns.
Thirteen patients with 15 fractures were treated. Eleven patients received a unilateral, two a bilateral, screw fixation. Twenty-seven screws were implanted. Continuous on-table traction was used in six cases. Mean radiological follow-up was 13 months.
Twenty-five (93%) screws were placed correctly. There was no impingement of screws on neurovascular structures. Union occurred in 12 (80%), delayed union in 2 (13%), and nonunion in 1 of 15 (7%) fractures. There was one screw breakage and two axial dislocations.
Sacroiliac CRPF of longitudinal fractures of the posterior pelvic ring is technically simple, minimally invasive, well localized, and stable. It should be done by an interventional/surgical team. CT is an excellent guiding modality. Closed reduction may be a problem and succeeds best when performed as early as possible.
评估在纵向骨盆后环骨折中采用计算机断层扫描（CT）引导下骶髂螺钉固定的闭合复位经皮固定（CRPF）的中期结果。记录影像学和CT随访模式。
治疗13例患者的15处骨折。11例患者接受单侧螺钉固定，2例接受双侧螺钉固定。共植入27枚螺钉。6例患者术中持续牵引。平均影像学随访时间为13个月。
25枚（93%）螺钉置入正确。螺钉未对神经血管结构造成压迫。15处骨折中，12处（80%）发生愈合，2处（13%）延迟愈合，1处（7%）未愈合。发生1例螺钉断裂和2例轴向移位。
骨盆后环纵向骨折的骶髂CRPF技术操作简单、微创、定位准确且固定稳定。应由介入/手术团队进行操作。CT是一种出色的引导方式。闭合复位可能存在困难，尽早进行成功率最高。
