Insights
Pelvic and acetabular fracture patients have high loss to follow-up rates. Male sex, gunshot wounds, and general trauma surgery increase this risk, while orthopedic surgery and operative treatment improve follow-up for these complex injuries.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Patient Outcomes
Background:
- Pelvic and acetabular fractures are increasing globally.
- No prior studies identified risk factors for loss to follow-up in these patients.
Purpose of the Study:
- Identify risk factors associated with loss to follow-up in patients with pelvic and acetabular fractures.
- Determine factors that improve patient adherence to follow-up care.
Main Methods:
- Retrospective review of 446 patients with pelvic and/or acetabular fractures (2015-2020).
- Data collected included demographics, injury details, treatment, and follow-up status.
- Statistical analysis to determine odds ratios for loss to follow-up.
Main Results:
- 61% of patients attended their orthopedic clinic follow-up.
- Gunshot wound mechanism (OR=2.134), male sex (OR=1.859), and general trauma surgery (OR=1.841) were significant risk factors for loss to follow-up.
- Operative treatment (OR=0.239) and orthopedic surgery discharge (OR=0.372) were protective factors for follow-up.
Conclusions:
- Male sex, ballistic injuries, and non-orthopedic discharge services are associated with higher loss to follow-up.
- Orthopedic surgical management and discharge are associated with better follow-up rates.
- Interventions are needed to improve follow-up adherence in this patient population.
Introduction:
Pelvic and acetabular fracture incidence is increasing worldwide for more than four decades. There is currently no evidence examining risk factors for loss to follow up in patients with these injuries.
Methods:
Patients presenting with pelvic and/or acetabular fractures at our institution between 2015 and 2020 were included. Demographic, injury, treatment, and follow up information was included. Excluded patients were those who sustained a pathologic fracture, has a course of treatment prior to transfer to our centre, or expired prior to discharge.
Results:
446 patients, 263 with a pelvic ring injury, 172 with an acetabular fracture, and 11 with combined injuries were identified. 271 (61%) of patients in our cohort followed up in Orthopaedic clinic (p = 0.016). With an odds ratio of 2.134, gunshot wound mechanism of injury was the largest risk factor for loss to follow up (p = 0.031) followed by male sex (OR= 1.859) and surgery with general trauma surgery (OR=1.841). The most protective risk factors for follow up with Orthopaedic surgery were operatively treated pelvic and acetabular fractures (OR=0.239) and Orthopaedic Surgery as the discharging service (OR=0.372).
Discussion:
Numerous risk factors exist for loss to follow up including male sex, ballistic mechanism, and discharging service. Investigation into interventions to improve follow up in these patients are warranted.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
