Osteochondral lesions are drilled with the aim of stimulating the growth of new cartilage to cover the defect (Pnidie 1959). This may be performed at arthrotomy or anthroscopically, but arthroscopic drilling is far from standard practice. Performed percutaneously, arthroscopic drilling by Kirschner wire can be hindered by difficulty with accurate placement, skidding off sclerotic bone and entan...

Most techniques of cranioplasty are expensive and require advance preparation if a custom-moulded prosthesis is to be used. Technical problems with cranioplasties using synthetic materials include sinking, elevation and rotation, while those with hydroxyapatite or bone graft cranioplasties include resorption and harvest site disfigurement. We report our technique of in situ cranioplasty using m...

Bone stock deficiency in primary as well as in revision total knee arthroplasty (TKA) represents a difficult problem to surgeon with regard to maintaining proper alignment of the implant components and in establishing a stable bone-implant interface. Different surgical procedures are available in these situations, for instances the use of bone cement, prosthetic augments, custom implant, and wi...

PURPOSE This study tested a bone-tendon allograft versus human dermis patch for reconstructing chronic rotator cuff repair by use of a canine model. METHODS Mature research dogs (N = 15) were used. Radiopaque wire was placed in the infraspinatus tendon (IST) before its transection. Three weeks later, radiographs showed IST retraction. Each dog then underwent 1 IST treatment: debridement (D), ...

Wire electric discharge machine (WEDM) is spark erosion in unconventional machining technique to cut hard and the conductive material with a wire as an electrode. The blanking die material SKD 11 is a high carbon and high chromium tool steel with high hardness and high wearing resistance property. This tool steel has broad application in press tools and dies making industries. In this research ...

We describe a patient who underwent arthroscopic pullout fixation for a posterior cruciate ligament (PCL) avulsion fracture. A 46-year-old female, injured in a fall while riding a motorcycle, was diagnosed with a right knee PCL tibial attachment avulsion fracture and underwent arthroscopic osteosynthesis. A Kirschner wire was drilled to a point just medial to the medial border of the anterior t...

INTRODUCTION Bone electrical potentials change with the force applied. Also, fracture alters the bone electrical potential, so it becomes more electronegative. These potentials have an important role in fracture healing, bone growth and remodelling. Literature data on the influence of fracture operative treatment on bone electrical potentials, and possible consequences of this influence, are sp...

Osteogenesis imperfecta (O.I.) is a genetic disorder with increased bone fragility and low bone mass. We report the history of a 17-year-old male patient with O.I. who presented a fracture of his left femoral shaft. He had osteogenesis imperfecta type I A according to Silence. He had presented two years previously an ipsilateral cervical fracture of the femur which had healed. Intramedullary fi...
