ABSTRACT
Background and Objectives: the meniscus has an important role in weight bearing, energy absorption and joint stability and congruency. Treatment in cases with meniscus damage or meniscus tear including is open or arthroscopic repair and menisectomy. One of the most important factors that influence on the patients outcome is restoration techniques. The purpose of this study was to compare strength of vertical and vertical cruciate double mattress suturing techniques in meniscus repair
Methods and Materials: in an experimental study 12 internal meniscuses of bulls has been divided into 2 equal groups. Vertical and vertical cruciate double mattress suturing techniques was done and compared with each other according to the resistance to tensile forces and restoring the gap stability
Results: in this study, the vertical knots average strength were 234.3 +/- 12.5 N and in vertical cruciate double mattress knots were 245.7 +/- 16.4 N. There was no significant difference between the two groups. Gap sustainability in the first group was 142.6 +/- 11.7 N and in a vertical cruciate double mattress was 182.4 +/- 8.7 N that the difference between two groups was significant [P =0.02]
Conclusion: the results of our study indicate vertical knot and vertical cruciate double mattress has similarly resistance. Sustainability gap repair of vertical cruciate double mattress is more than vertical knot techniques. Vertical cruciate double mattress is makes for greater stability against tensile force
ABSTRACT
Background and Objectives: hemiarthroplasty [HA] is generally considered to be the treatment of choice in the most elderly patients with a displaced fracture of the femoral neck. Hip fractures especially in the elderly imposed many problems to health care system. In these patients with proper treatment and rapid ambulation complications is reduced. The purpose of this study was to evaluate the results of bipolar hemiarthroplasty treatment in the traumatic femoral neck fractures
Materials and Methods: in this descriptive analytical study, 50 patients candidate to hip arthroplasty were studied. Short-term complications and functional abilities were assessed with the Harris Hip Score questionnaire
Results: in this study, 40 patients with a mean age of 76.3 +/- 8.2 years, including 12 men [30%] and 28 women [70%] were studied. The mean functional hip score was 78/02 +/- 20.8. Between men and women was significant statistical difference according to hip function scores which men had earned a better score than women. The main complications were a dislocation and infection. In three cases there was a need for further surgery. At follow-up 35 patients [87.5%] had no pain, and 30 [75%] walked with a cane
Conclusion: according to our results bipolar hip arthroplasty for hip fractures has good functional outcome. As regards to possible suitable placement for each patient is more stable and is not associated with significant complications
