Insights
Total hip replacement using proximally coated stems showed no revisions and high Harris Hip Scores. Bone remodeling occurred without stress shielding, though further observation is needed for specific zones.
Area of Science:
- Orthopedic surgery
- Biomaterials engineering
- Radiology
Background:
- Total hip replacement (THR) is a common procedure for hip joint issues.
- Proximally coated stems are designed to improve bone integration and reduce stress shielding.
- Understanding the long-term clinical and radiological outcomes of these stems is crucial for patient care.
Abstract:
Clinical and radiological results of total hip replacement with proximally coated stems are discussed. Material included 90 hips (50 ABG stems, 40 Level III stems) in 83 patients (59 females, 24 males), mean age 48 years (range 17-22) and mean follow-up of 27 months (range 1-5 years). No stems were revised, the average Harris Hip Score at last follow-up ranged from 89 to 91 points. Stress transfer around the proximal part of the stem resulted in endosteal osteogenesis in the 2nd and 6th Gruen zones and changed trabecular orientation. There was no evidence of bone resorption due to stress shielding. Peri- and endosteal bone reaction in the 3rd and 5th Gruen zones need longer follow-up.
