The Short-term Clinical Observation Of The T.o.p. Cup And Ribbed Stem Uncemented Hip System

Objective:By clinical and imaging follow-up to observe the clinical use of short-term efficacy of the treatment of hip advanced disease T.O.P. Cup and Ribbed stem cementless hip system, and provide scientific and objective basis for the clinical application of the system.Methods:We present a retrospective study of57uncemented hip system replacements in50patients performed form Shandong University of Traditional Chinese Medicine Affiliated Hospital of joint orthopedic March2010-March2012. Clinical evaluation of the Harris hip score for the standard, with a total score of100points,90to100excellent,80to89are divided into good,70-79is divided into moderate,<70is divided into poor. Imaging assessment of hip ray films were analyzed according to the postoperative and follow-up anteroposterior film femoral stem and acetabular cup were use of Gruen and Delee&the the Charnley partition method. Understand the prosthesis-bone interface is the photic zone and hardening with, and understand the prosthesis displacement, and the prosthesis and the femur exposure through bilateral hip anteroposterior film.Results:The actual clinical and hip X-ray films were followed up for50cases,57hip, follow-up rate of100%. A minimum of3months follow-up time, up to15months, an average of8.24months. The average Harris hip score from the preoperative average47.56±11.74(21.3±69.95) points to a postoperative average of88.38±6.17(69～98) points, with pre-treatment significantly improve. Application SPSS17.0statistical software, design information in the paired t-test analysis, t=-21.136, P=0.000, P<0.01, two groups have significant differences.22cases were excellent, good22cases, moderate in5cases and poor in1, and the excellent rate of88%. X-ray showed the acetabulum and the femoral stem prosthesis is satisfied with the prosthesis-bone interface photic zone and hardening with the prosthesis without displacement, and signs of loosening and infection. Does not appear after wound infection, deep venous thrombosis, periprosthetic fractures, dislocation, sciatic nerve damage and other complications. Hip function in patients with significant improvement in pain relief thorough, stability and flexibility enhancements, can not crutches to walk independently, gait returned to normal, and live independently.Conclusion:The satisfaction of the short-term clinical efficacy of using the T.O.P. cup and Ribbed stem for total hip arthroplasty can be widely used in clinical practice, relieve patients’pain, improve quality of life of patients with advanced disease of the hip. Adequate preoperative preparation, detailed understanding of the anatomical structure of the acetabulum and the proximal femur, a skilled operative techniques, postoperative guidance and rehabilitation training is the key to successful treatment.
