Pelvic nonunion and associated stress fractures are under-reported. Nonunited stress fractures can cause continued buttock pain and pelvic instability. The aim of this study is to report on our experience managing patients with ongoing pain following nonunion of PAO. Patients and methods: 8 patients presented to a tertiary referral pelvic service with symptomatic PAO nonunion between 2015-2018. All patients underwent open reduction internal fixation of the superior pubic ramus nonunion, with ipsilateral iliac autograft, at an average of 48.1 (15–82) months following initial osteotomy. Demographic and perioperative data were recorded. Follow-up was on average to 9.9 months, once union was confirmed radiographically. Results: All patients were female and average age was 31.8 (18–41) years. In 7/8 (87.5%) patients a modified S...

A prospective study assessed whether trainees taught this ABC aide memoire gave better priority driven care in simulated patient scenarios. They were compared directly to colleagues undergoing the same pelvic training but without reference to the ABC concept. Orthopaedic trainees were formally assessed by viva scenario upon their pelvic trauma management 6 weeks after a pelvic trauma teaching event. Trainees all received standard pelvic trauma teaching but were randomised into two groups. One group alone had an introduction to the ABC algorithm. Inclusion criteria were trainees belonging to the same deanery teaching group with similar levels of training and experience in pelvic trauma. Those completing a pelvic trauma post or teaching in pelvic trauma were excluded. There were 20 trainees included and three scenarios giving 60 scores. The mean year of t...
