Background& Objective: The acetabular bone deficiency secondary to acetabular fractures presents a complex clinical problem and a big challenge to the orthopedic surgeons due to the technical difficulties related to this deficiency, considering that significant number of patients treated either surgically or without surgery will require T.H.A in the future. The purpose of our study was to determine the outcome of T.H.R performed in patients with a history of acetabular fracture. Materials & Methods: We performed T.H.R in 21 patients with previous acetabular fractures in Al-Assad Hospital between2004-2009prespectively, these cases were divided into 3 groups: -first group formed of 7 patients were treated conservatively. Second group formed of 9 patients did an open reduction and internal fixation by screws and plates. -Third group formed of 5 elderly patients with fresh acetabular fractures and were treated primarily by a total prosthesis with use a reinforcement Muller ring . For the clinical evaluation of our cases we used the modified Harris Hip Score Scale and for the radiological evaluation we used the Delee and Charnley scale system . Results: Our overage Harris Hip Score was 83.(80 for the first group, 86 for the second group, and 83 for the third group). -No complications were encountered intraoperative, in the early postoperative period one case developed superficial wound infection and treated by repeated dressing and antibiotic, there was one case of D.V.T on the 4th day treated by rest and anticoagulant, and one case developed loosening of acetabular component 8 months after T.H.A and underwent to revision. Conclusion: T.H.R in acetabular fractures despite the difficulties faced during the procedure is a safe and effective way to salvage the hip when secondary osteoarthritis develops, open reduction and internal fixation of acetabular fractures may have benefits even if it fails to prevent posttraumatic arthritis .Furthermore the clinical results of T.H.R after surgical treatment of acetabular fractures are better than it after conservative treatment of these fractures. Reinforcement ring is an ideal solution when the decision of T.H.R is taken as a primary treatment of acetabular fractures depending on the indications described by Joly.

The rate of venous thromboembolism is unacceptable without prophylaxis. Venographic studies of patients without prophylaxis show that the deep vein-thrombosis rates range from 40-84% after total knee replacement, and rates of pulmonary embolism ran ge from 1.5-10%. Surgeons must balance the need for thromboprophylaxis with the need to avoid bleeding complications. The purpose of this study is to evaluate the status of thrombo prophylaxis after primary total knee replacement in ALMouassat university hospital, and to improve our outcome in future, to get better results and fewer complications.
THA as a primary management for acute fractures around the hip should generally be reserved to a very selected few patients where the general condition, life expectancy, age, bone quality, pathological changes, type of injury... Primary THA for a cute fractures around the hip done with proper patient selection under the proper condition, and requirements can result in good clinical results with excellent short-term survival of the prosthesis.
coxathrosis secondary to the untreated developmental dysplasia of the hip is still encountered against all the screening and early treatment methods.T.H.A in DDH presents challenging surgical problems to the orthopedic surgeons due to the associate d anatomical changes and the technical difficulties related to the bone deficiency in the acetabulum. The purpose of the study is to examine the clinical and technical problems associated with reconstruction of the hip in patients with congenital dysplasia and to offer recommendations for their Solutions.
This study includes ٨٠ cases of total knee Arthroplasty, They were treated in Al-Moassat Hospital during the years ٢٠٠٠- ٢٠٠١. Idiopathic primary osteoarthrihis was the main reason for total knee Arthroplasly. Some cases of Rheumatoid arthritis w ere observed too. The short term chinicaln gools of total arthoplasty include restoration of the normal activity of the limb and pain relief , which can be obtained under the proper surgical condition, and requirements, supported by better understanding of the biomechanics of the knee joint and good rehabilitation there after.
The aim of this clinical study was to investigate the intraocular pressure (IOP) reduction after selective laser trabeculoplasty (SLT) in patients with primary open-angle glaucoma (POAG). The research has been done in Alassad Hospital, Tishreen unive rsity, Lattakia, from Feb 2009 to Feb 2011. Fifty eyes with uncontrolled POAG were treated with a frequency doubled, Q-switched Nd:YAG laser (532 nm).The pattern of treatment was applying approximately 50 burns to 180 degrees of the trabecular meshwork at energy levels ranging from 0.40– 0.92 mJ per pulse. After SLT eyes were maintained with the identical hypotensive medical therapy as that before treatment. IOP was measured before treatment, 1 and 7 days after treatment and 1, 3, 6 and 12 months after treatment. The mean pretreatment IOP was 22.48 (SD 1.84) mmHg. At the end of 1 month follow-up period the mean reduction of IOP was 4.86 mmHg (21.6%); after 3 months the mean reduction was 5.66 mmHg (25.2%); after 6 months the mean reduction of IOP was 5.06 mmHg (22.5%); at the end of 12 months follow-up period the mean reduction was 4.92 mmHg (21.9%). It can be concluded that SLT presents a new and effective method of IOP reduction in the treatment of POAG.
