Clinical and biomechanical investigation of an increased articular cavity depth after distal radius fractures: effect on range of motion, osteoarthrosis and loading patterns.
After fracture, distal radius malunion with dissociation of the volar and dorsal ulnar fracture fragments can lead to an increased articular cavity. ⋯ Alterations in contact biomechanics could be one reason for the higher incidence of posttraumatic osteoarthritis when a deeper central impaction of the distal radius is present. From a clinical and experimental point of view, restoration of the normal shape of the distal radius is considered to minimize the risk for posttraumatic radiocarpal osteoarthritis.

Long-term outcome of medial open reduction in developmental dysplasia of hip.
Long-term outcome of medial open reduction (MOR) was examined. We aimed to evaluate the effects of MOR on hip development in developmental dysplasia of hip (DDH). ⋯ Medial open reduction is effective and safe treatment method in DDH. Early concentric stable reduction with MOR improved results.

The functional outcome of acute scapholunate ligament repair in patients with intraarticular distal radius fractures treated by internal fixation.
Intra-articular fractures of the distal radius (DRF) are associated with a twofold increase in the risk of scapholunate ligament injury (SLI). The aim of this study was to compare functional outcome, pain, and disability between patients with operatively treated DRF and either an acute, repaired scapholunate ligament injury or no ligament injury. ⋯ The outcomes of intraarticular fractures of the distal radius with operatively treated associated SLI are comparable with the outcomes of intraarticular fractures of the distal radius without associated SLI.

Case ReportsFracture of the talar neck associated with a compression fracture of the calcaneocuboid joint in a 5-year-old child: a case report.
The objectives of this present case study are to report a rare combination of a displaced talar neck fracture with a compression fracture of the calcaneocuboid joint in a 5-year-old child and to describe its radiological features, surgical treatment and clinical outcome. A 5-year-old male boy was injured in a car accident in which his left foot underwent one of the tires. On arrival at the hospital, a displaced talar neck fracture associated both with a cuboid fracture and compression of the articular surface of the cuboid at the calcaneocuboid join was identified. Fractures were fixed surgically. Leg was protected with a below-knee plaster split immobilization and non-weight-bearing for 5 weeks. After that period, the patient initiated a rehabilitation protocol with active and passive motion exercises. ⋯ V.

Comparative StudyGraft failure versus graft fixation in ACL reconstruction: histological and immunohistochemical studies in rabbits.
The causes of graft failure after anterior cruciate ligament (ACL) reconstruction are multifactorial including the methods of graft fixation. The purpose of this study was to examine the ACL graft failure in three different methods of graft fixations including interference screw fixation, suture-post fixation and combined interference screw and suture-post fixation. We hypothesized that the fixation method after ACL reconstruction can affect the graft healing in tibial tunnel. ⋯ In immunohistochemical analysis, the combined fixation and suture-post fixation groups showed significantly higher BMP-2 and VEGF expressions than interference screw (P < 0.01). The tendon-bone healing after ACL reconstruction was affected by the method of graft fixation. Combined fixation with interference screw and suture-post reduced graft-tunnel micromotion and improved the graft healing in tibial tunnel.
