Evaluation of different intraarticular injection volumes to assess optimum efficient amount; an experimental study in rat knee joints.

Introduction: The injection amount of solutions differs in wide ranges, from 20 to 200 μL in intraarticular injections experiments that was carried out with rats. The 10-fold difference between applied volumes is not acceptable since injection errors might affect the outcomes of the studies significantly. The excessive amount of solution that was injected into the knee joint of rats might end up with leakage of the solution from injection aperture, and damage the articular structures etc.

Intra-articular injection of hydrogen sulfide decreased the progression of gonarthrosis.

Gonarthrosis was induced surgically in the left knees of rats and left for 6 weeks for the development of disease.

Acetabulum Protrusion Following Ceramic Liner Fracture: A Case Report.

Hip arthroplasty is an extremely satisfying treatment method for coxarthrosis which is in increasing use throughout the world. However, loosening of the prosthesis is a significant complication and to overcome this, ceramic liners are increasingly being selected. If the survival of ceramic surfaces is prolonged, there is a risk of fracture of the ceramic materials.

Minimally Invasive Surgical Approach Using an Equal-Sized Plate as an External Guide to Lateral Malleolar Fractures.

Background: For minimally invasive percutaneous plate osteosynthesis (MIPPO) techniques applied to fractures of the lateral malleolus, there is no external guide for inserting the plate, determining the incision, and inserting the screws as used for fractures in other regions. With MIPPO, fluoroscopy exposure is unavoidable. The MIPPO technique is advantageous for patients; however, the unavoidable problem with this method for the surgical team is repeated exposure to fluoroscopy.
