Total Hip Arthroplasty in Patients with Bilateral Upper-Limb Amelia

We report two patients, a 43-year-old man and a 26-year-old woman, with bilateral absence of the upper extremity and severe hip osteoarthritis. The involved hip was the dominant extremity for both patients. Total hip arthroplasty (THA) was performed using a posterior approach with dual-mobility implants. Both patients report satisfactory outcomes including the ability to perform the significant range of motion required for daily activities such as toe-to-head motion.In patients with extreme range of motion requirements such as those affected with bilateral upper-limb amelia, a posterior THA with a dual-mobility implant may be safely and successfully performed to treat disabling hip osteoarthritis.
