Interventions
Vitamin E doping of highly cross-linked polyethylene is a proposed method for insuring long-term oxidative stability of highly cross-linked ultra-high molecular weight polyethylene for use in total joint arthroplasty. In vitro research and development studies have shown that this material has improved wear performance, retention of mechanical properties, and a high resistance to oxidation due to the anti-oxidative properties of Vitamin E.
Eligibility Criteria

- Diastrophic variant
- Fracture of the pelvis
- Fused hip
- Slipped capital epiphysis

- Traumatic arthritis Patients aged over 20 Patients with limited co-morbidity - ASA I - III
You may not qualify if:
- Absolute contraindications include: infection, sepsis, and osteomyelitis
- Relative contraindications include:
- uncooperative patient or patient with neurologic disorders who are incapable of following directions,
- osteoporosis,
- metabolic disorders which may impair bone formation,
- osteomalacia,
- distant foci of infections which may spread to the implant site,
