Macroporous biphasic calcium phosphate ceramic performance as bone graft substitute

Twenty nine patients with complicated orthopaedic problems for whom enough bone graft was difficult to obtain, 24 patients with fractures and 5 patients with bone cysts were included in this study. Macroporous biphasic calcium phosphate ceramic [MBCP] is used as bone graft substitute. The efficacy of [MBCP] was followed, the mean follow up period was 16 months. It was concluded that [MBCP] proved to be biocompatible and is tightly bond with host bone

Comparative study of M.R.I. and arthroscopic findings of the injured knee joint

The knee problems are very common disorders specially menescal tears Osteoathritis, and ligamentous injurye the M.R.I and arthroscope are the most accurate recent diagnostic tools. We examined 26 patients, 18 males and 8 females with age ranged from 20-60 years. all patients are carefully examined clinically, routine laboratory investigation and plain x-rays of the knee were done M.R.I was performed to all patients before; performing diagnostic arthroscopy diagnostic arthroscopy was done in the theatere under general or spinal anesthesia through the lateral approach of the knee with the leg free at the edge of the table in 90 flexion the patients usually discharged from the hospital in the same or in the 2nd day surgery. The aim of this work is to evaluate the diagnostic value of the M.R.I of the knee joint with correlation of the arthroscopic findings and the results of the M.R.I. Our study reveal that: M.R.I can detect complete ACL and PCL tears with high sensitivity [100%] but this sensitivity decrease very much for partial ACL tear and can't detect ACL laxity and the sensitivity to diagnose meniscal injury is about 80%. The arthroscope is can't diagnose collateral ligaments injury because these structures are extra articular

Evaluation of early results of reduction and pinning of acute SCFE

Fourteen patients with 17 Acute slips of S.C.F.E. were investigated clinically and radiologicallly. They were managed by gentle traction in internal rotation for 5-7 days, followed by percutaneous pinning. The results were satisfactory in 94. 1%. No case developed avasacular necrosis

Chair pelvic osteotomy in perthes disease

12 Chiari Osteotomies performed on patients with Perthes disease who were followed for three years is presented. The average age at operation was 8 years 9 months. Catterall grading was mainly group IV. Chiari osteotomy provided satisfactory femoral head coverage with a decreased acetabular index and a 19.6 improvement of the wiberg angle. Good femoral coverage was related to age at operation and the site of the osteotomy on the upper rim of the acetabulum. At follow-up, the results of femoral head sphericity studied by Mose measurements were favorable under Catterall grading
