PURPOSE To compare outcomes of 3 fixation modalities for scaphoid non-union. METHODS 27 men and 6 women aged 20 to 48 (mean, 28) years with non-union of the scaphoid involving the proximal pole (n=13), waist (n=12), and distal pole (n=8) were randomised to undergo the Herbert screw fixation (n=11), the Matti Russe bone grafting (n=9), or the Kohlman modification of vascularised muscle pedicle...

BACKGROUND Complications in posterior pedicle screw fixation using a conventional posterior approach for thoracolumbar fractures include vertebral height loss, kyphosis relapse and breakage, or loosening of instrumentation. The purpose of this study was to evaluate the clinical effects of transpedicular bone grafting and pedicle screw fixation in injured vertebrae using a paraspinal approach fo...

Avascular necrosis (AVN) of femoral head needs to be addressed early in the course of the disease, to prevent progression to osteoarthritis. A revascularizing procedure which can help preserve the head should be considered in young adults to alleviate the need for total hip arthroplasty. We included 40 cases (53 hips) of AVN of femoral head operated with Sartorius muscle pedicle iliac bone graf...

OBJECTIVE To investigate the surgical outcome of a universal pedicle screw-V rod system and isthmic bone grafting for isthmic spondylolysis. METHODS Twenty-four patients with isthmic spondylolysis at L5 and grade 0-I spondylolisthesis (Meyerding classification) received isthmic bone graft and stabilization using the universal pedicle screw-V rod system. Back pain was evaluated using the visua...

Objective: To explore the efficacy of an intracorporeal bone grafting technique in the treatment of type A thoracolumbar fracture. Methods: From Feb 2010 to March 2012, a series of 28 patients type A thoracolumbar fracture with moderate to severe osteoporosis who met our inclusion criteria were treated by a combination of percutaneous pedicle screws posteriorly and intracorporeal grafting throu...

Failure of union of the tibia with a large defect is difficult to treat, especially in the presence of sepsis and adherent scars. Conventional methods of fixation and bone grafting are not easily applicable. Experiments on Macaca monkeys showed that a vascularised pedicle graft of the shaft of the ipsilateral fibula could be fixed across a defect in the tibia and remain viable, even if it was i...
