Total hip arthroplasty in patient with hip fracture and congenital pubic diastasis.

Congenital pelvic deformities, such as pubic diastasis, significantly complicate the surgical planning and execution of total hip arthroplasty (THA), the gold standard for treating degenerative hip disease unresponsive to conservative measures. These challenges are exacerbated in the context of trauma, because of disrupted anatomical landmarks and soft tissue imbalances. THA becomes particularly demanding in cases involving traumatic femoral neck fractures in patients with congenital anomalies of the pelvis. We present a unique case of a 62-year-old man with an acute, post-traumatic left-sided hip fracture, and a history of congenital bladder exstrophy and pubic diastasis, who successfully underwent THA. Meticulous preoperative planning with three-dimensional reconstruction software was essential in overcoming the anatomical challenges posed by this case, enabling our successful outcome.
