The investigators aim is to determine if the cannulated Bone Bolt® screw system will provide improved post-operative pain control as compared to standard cannulated screw system fixation for the operative treatment of LC1 fractures (primary outcome). Hypothesis: Patients treated with the cannulated Bone Bolt® screw system will experience a clinically important difference (1.5 points) in post-operative pain as measured by the Visual Analog Scale (VAS) compared to patients treated with standard cannulated screw system fixation.
Lateral Compression type-1 (LC1) fractures of the pelvis represent the most common injury to the pelvic ring, accounting for more than 50% of all pelvic ring injuries. These injuries occur secondary to a lateral compressive force on the pelvic ring causing an internal rotation force coupled with medialization of the impacted hemi-pelvis. Despite their prevalence, treatment algorithms for these injuries remain controversial. When significant deformity exists (\>1cm displacement) the preference is typically for operative fixation as this has been listed repeatedly as an indication for surgery. I…
