Biomechanical comparison between rigid and non-rigid posterior stabilization systems following lumbar interbody fusion has been conducted in several studies. However, most of these previous studies mainly focused on investigating biomechanics adjacent spinal segments or spine stability. The objective the present study was to compare biomechanical responses devices when using different instrumen...

The medial patellofemoral ligament (MPFL) has been recognized as an important soft tissue restraint in preventing lateral patellar translation. As many patients with acute or chronic patellar instability will have a deficient MPFL, reconstruction of this ligament is becoming more common. Appropriately, significant research has been undertaken regarding graft biomechanics and techniques, as intr...

Surgical environment is becoming increasingly challenging for the cardiac surgeon since off-pump coronary arteries bypass grafts and minimally invasive approach came up. The suture technique for coronary anastomosis construction is becoming inadequate to meet new surgeons’ demand. Therefore, there is an increasing need for alternative ways to perform coronary bypasses. This article reviews the ...

Objectives: The aim of this study was to investigate the effect cartilage thickness mismatch on tibiotalar articular contact pressure in osteochondral grafting from femoral condyles medial talar dome using a finite element analysis (FEA). Materials and methods: Flush-implanted performed centromedial aspect plugs with two different thicknesses. One had an equal recipient second plug thicker repr...

Major advances have been made recently in the areas of posterior cruciate ligament (PCL) anatomy and biomechanics, and several basic science studies have attempted to clarify the variables relevant to the optimal methods of PCL reconstruction. The emerging science concerning the PCL relates primarily to the biomechanical benefits of the inlay technique of tibial fixation compared with tradition...

Multiple ligament knee injuries, although rare, are severe injuries that often result in the loss of the passive and active knee stabilizers as well as often being associated with the compromise of neurovascular structures. Treatment of these injuries is controversial, and results after surgery are often poor. After sustaining injuries to multiple ligaments, the knee is at a biomechanical disad...

Although successfully used, long strut grafts are vulnerable to dislodgment, displacement, fracture, and nonunion, which can require revision surgery; thus, meticulous preparation of the vertebral endplate along with exact sizing and harvesting of the bone graft with plating are essential for successful outcomes. Biomechanical data and previous clinical studies support the addition of posterior...

To describe a new procedure of total hip replacement in patient with severe developmental dysplasia of the left hip, using technique of acetabular reconstruction with autogenous bone grafts and subtrochanteric shortening femoral osteotomy. Total hip replacement done in January of 2003. The Eftekhar's classification was used and included type D, neglected dislocations. Bone graft incorporated in...

The increasing need for total hip replacement (THR) in an ageing population will inevitably generate a larger number of revision procedures. The difficulties encountered in dealing with the bone deficient acetabulum are amongst the greatest challenges in hip surgery. The failed acetabular component requires reconstruction to restore the hip centre and improve joint biomechanics. Impaction bone ...
