Introduction: Total hip arthroplasty [THA] has established itself as the surgery of the century and with the advent of improved prosthetic design and developments in the bearing surfaces and materials more are expected by surgeons and patients. The purpose of this study was to evaluate the clinical and radio¬graphic results of Delta Motion hip system in patients undergoing THA.
Conclusion: Delta Motion hip system shows excellent function, Harris Hip Score and a low rate of complications. As a monobloc system, it allows optimization of head diameter to acetabular cup ratio, head engagement, and stability of the hip.
Materials and Methods: This study comprised of 32 hips (31 patients) conducted at Max Hospital, Delhi. Patients with degenerative hip diseases were included whereas patients with an active infection, unable to give consent for surgery, neuromuscular diseases and revision total hip replacement were excluded. e mean age was 44.7 years (range, 35-66 years) and mean follow-up was 65.6 months (range, 48-74 months)
Results: The Harris Hip Score improved from a mean of 47.8 (30-60) preoperatively to 86.8(85-90) postoperatively. 97.5% of patients were able to participate regularly in leisure and daily routine activities. One patient had acetabular cup migration with an angular change of more than 10° and experienced squeaking. e mean abduction angle and anteversion of acetabular component were 38.6 degrees +/- 6.2 (range 27-54 degrees), 16.4 degrees +/- 4.6 (9-24 degrees).
