Background –Total hip arthroplasty went through the many changes in recent years.The trend is towards a cementless shorter stems and a proximal implant anchoring with the preservation of pt. own bone substance. One stem representative of these design is the metha modular short stem prosthesis. This design justifies the expansion of the indication to younger patients,and should fulfill their requirements in terms of quality of life and activity in every day life. At the same time,the opportunity to leave as many bone structure untouched is possible leaving considerable bone for a potential revision case.
Material and Method: To determine the clinical and radiological outcome in 25 patients of total hip replacement with short stem (metha) in the department of orthopaedics at Amandeep hospital, Amritsar, Punjab, all patients were followed for a period of one year, with harris hip score being calculated pre operatively and post operatively at 3month,6month and at time of completion of study.
Result: The final mean harris hip score of 25 patients with mean age 35.78(+/-9.48) yrs. at the end of the study was 97.15(+/-1.06) which has increased from a pre op value of 42.44 (+/-3.08). No features of implant loosening no evidence of component migration were found radiologically, while all radiographs demonstrated the implants being properly seated with evidence bone ingrowth.
Conclusion: The Metha metaphyseal stem is worth recommending as a solution to be considered in young patients with advanced degenerative changes in the hip joint. Primary stability of implant is very effective because of metaphyseal anchorage within the closed ring of femoral neck and conical shape of implant. The coating of proximal surface of implant with a microporous pure titanium coating(plasmapore) with a thin layer of dicalcium phosphate dehydrate in order to achieve a strong secondary stability and accelerated bony ingrowth is very effective.
