background anterior cruciate ligament (acl) injury is the most common sports injury in both athletes and nonathletes; it can cause disability if not treated correctly. in cases with minor injuries, conservative treatments suffice. but, in cases with acl tear, surgery by different methods and autografts are indicated. the most prevalent method for acl reconstruction is the use of hamstring tendo...

Results Twenty-five patients were operated in emergency following complex MCP, PIP and DIP fractures and 7 patients at more than one month following trauma due to neglected dislocation or complications of arthroplasty. The duration of distraction was 6 weeks. Associated osteosynthesis was performed in 3 cases. The mean follow-up was 36 months. Grip strength was 85% of the contralateral side. Ac...

Seven cases of Chance fractures of the spine in children are presented, with their association to intra-abdominal injuries secondary to seatbelt use. A discussion and review of the literature suggest an increasing frequency of this particular injury with a high association given the clinical sign known as the "seatbelt sign." Also reviewed is the association of intra-abdominal injuries secondar...

BACKGROUND Gap-balancing is an alignment method for total knee arthroplasty with the goal of creating uniform tension in the periarticular soft-tissue restraints and equal laxities throughout the arc of flexion. However, there is little evidence that achieving equal laxities prevents either overly tight or overly loose soft-tissue restraints after total knee arthroplasty. Accordingly, the purpo...

BACKGROUND A capsular shift procedure has been described for the treatment of hip instability; however, the biomechanical effects of such a shift are unknown. PURPOSE To create a cadaveric model of hip capsule laxity and evaluate the biomechanical effects of a capsular shift used to treat hip instability on this model. STUDY DESIGN Controlled laboratory study. METHODS Eight cadaveric hips...

BACKGROUND AND PURPOSE Because of the oblique orientation of the posterior cruciate ligament (PCL), flexion gap distraction could lead to anterior movement of the tibia, which would influence the tibiofemoral contact point. This would affect the kinematics of the TKR. We assessed the flexion gap parameters when the knee is distracted during implantation of a PCL-retaining TKR. Furthermore, the ...

Objective: The current study was aimed at introducing a novel method to manage the mangled extremity by upper limb reconstruction using distraction osteogenesis. Methods: A 25-year-old man was admitted to our hospital after a severe mangled injury, his right forearm bones and the surrounding soft tissues were compromised. After initial debridement, the infection of his right forearm recurred. U...

reviews in many countries indicate that drivers often talk on mobile (cell) phones. studies have been done on possible effects of concurrent mobile phone use on driving performance. previous studies have found that phone talking could impairs performance on simulated or instrumented driving tasks, using such measures as reaction time, following distance, and situational awareness. most of these...
