Total Hip Arthroplasty With Acetabular Fixation: An Unexpected Complication — by Al-Achraf Khoriati, MBBS, BSc, MRCS
The incidence of vascular injuries associated with total hip arthroplasty is low. However, several vascular structures are at risk of injury within the pelvis. If left untreated, injuries to the external iliac, femoral and obturator vessels may be associated with severe morbidity and mortality. In this report, an acute vascular complication that had an unusual presentation is highlighted. Read more
A number of reports have advocated the necessity of preoperative imaging2,12with computed tomography or magnetic resonance imaging to adequately plan complex acetabular surgery. The author believes that this case emphasizes the importance of adequate radiographic planning with the appropriate modality in cases where fixation may prove complex. In such complex cases, the use of a C-arm intraoperatively is a necessity. In this case, it would have avoided placement of a screw so deeply beyond the lamina quadrilatera.
