[Strength of vertical and vertical cruciate double mattress suturing techniques in meniscus]

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

[Comparison the results of Salter Osteotomy versus Femoral Osteotomy after open reduction in treatment of developmental Dysplasia of Hip]

Background and Objectives: Congenital dislocation of the hip [DDH] is a common cause of morbidity in different communities. Therapeutic implications include reduction and surgical stabilization of the hip joint. The purpose of this study was to compare the results of femoral osteotomy with Salter osteotomy

Materials and Methods: In a descriptive analytical study on 40 children 23 were treated with salter osteotomy and 17 cases underwent femoral osteotomy therapeutic outcome and complications were compared between two groups. Results were analyzed using Mc.Kay classification

Results: Studied group were 40 children [age 4.3 +/- 1.5 years M/F 17/23]. All patients in both groups had stable hip joint after treatment, and all patients achieved full range of joint motion. Trendelenburg gait was improved in all patients in both groups. Excellent results was achieved in 65% after Salter osteotomy and in 47% of cases femoral osteotomy, the difference was not statistically significant. The most important complication in Salter osteotomy was avascular necrosis of femoral head in 13% of the treated patients. It was not detected in femoral osteotomy method. On the contrary in femoral osteotomy, limb length discrepancy was the most important complication observed in 5 patients [29.1%]

Conclusion: Femoral osteotomy and Salter both methods are successful in stabilizing the hip joint. Both femoral and salter osteotomy methods could successfully stabilize the hip joint

Adolescence spinal epidural abscess with neurological symptoms: case report, a lesson to be re-Iearnt

Epidural abscess of the spinal column is a rare condition that can be fatal if left untreated. It promptly progresses and can cause neurologic paralysis, urinary retention or cauda equina syndrome. Compromised immune system that occurs in patients with diabetes mellitus, AIDS, chronic renal failure, alcoholism, or cancer is a predisposing factor. It mostly occurs in adults. Here we would like to report a case of spontaneous pyogenic lumbar epidural abscess with neurological deficit diagnosed in a 15 year old boy. We treated this case successfully with surgical microscopic decompression and drainage

A Short Term Follow Up Comparison of Genu Varum Corrective Surgery Using Open and Closed Wedge High Tibial Osteotomy

Introduction: Knee deformity associated with osteoarthritis (OA) is one of the most common complications seen in patients referred to orthopaedic surgeons. High tibial osteotomy (HTO) is an accepted method for treatment of medial knee osteoarthritis with varus deformity. The aim of this study was to compare results of osteotomy methods in patients with genu varum (GV) deformity. Methods: In this cohort study, the sample consisted of 32 patients with genu varum deformity (42 knees) who were divided into two groups and matched according to age and gender. The patients were treated with open or closed wedge osteotomy. After surgery, they were followed-up and compared for 6 months. Results: The sample consisted of 25 women (87.2%) and 7 men (21.8%). Ten patients (31.2%) presented with bilateral deformity. The incidence of complications was the same for both procedures (12.5%); this included one peroneal nerve injury following closed wedge surgery. Overall, patient satisfaction was 87.5% and 75% for the open and closed wedge methods respectively. Operative time, days to full weight bearing, and days to return to routine activities were significantly shorter for patients treated with the open wedge method (p<0.001). Conclusion: Open wedged HTO is associated with shorter operating time, shorter recovery time, higher patient satisfaction, and probable lower risk of neurological injury.

Comparison between ender and unreamed interlocking nails in tibial shaft fractures

To compare ender nails and unreamed interlocking nails in a randomized clinical trial study. From March 2001 to March 2003, 131 patients with tibial fractures of the central two thirds of the tibia were admitted to the emergency ward of Shohada Hospital, Tabriz, Iran and were randomized to either an ender tibial nail or an undreamed interlocking tibial nail as their primary treatment. Age, gender, types of fracture, and surgical outcomes were recorded at the time of surgery, during hospital stay, and during the course of 9 months follow-up. Sixty-seven patients underwent surgery with interlocking nails and 64 with ender nails. No statistically significant difference was found between the 2 groups concerning mal-union, delayed union, and device failure. Durations of hospital stay, and time needed to achieve union was significantly higher in the unreamed interlocking group. Non-union and infection rate were higher in the ender group [p<0.05]. The results of our study support those of other studies that indicate the choice between the 2 methods of unreamed nailing is mainly controversial, depending on the priorities of the patient and surgeon
