C-arm image intensifier or x-ray image intensifier is an imaging component that converts X-rays into a visible image and is a commonly used gadget in orthopedic surgeries. It is also used in many other procedures like gastroendoscopy, vascular surgery, neurosurgery, etc. C-arm machines are fluoroscopy machines and are commonly called as image intensifiers. Fluoroscopy is […]

Interfragmentary Screw or Lag Screw Fixation
An interfragmentary screw or lag screw is the screw that is used to compress fracture fragments. The screw is placed perpendicular to the fracture after it has been reduced and drilled in a way that while it engages the distal cortex, it just slides through the hole in the near cortex. As the screw is […]
What Is Femoral Offset and Its Significance?
Femoral offset is the distance from the center of rotation of the femoral head to a line dissecting the long axis of the femur. In the case of total replacement of the hip, the offset is considered as the distance from the center of rotation of the femoral head to a line bisecting the long […]
Kirschner Wire or K-Wire and Its Uses
Kirschner wire or K wire was invented by Martin Kirschner in 1909. They have a great role in the management of orthopedic trauma and the correction of deformities. Kirschner wire is also known as K pin. Kirschner wires are pointed stainless steel wires that can be used in multiple roles during internal fixation. These can […]
Trigger Point Causes, Types and Treatment
Also called a myofascial trigger point, the trigger point is a hyperirritable spot in skeletal muscle. These are associated with palpable nodules in taut bands of muscle fibers. It is believed that palpable nodules are tiny contraction knots and a common cause of pain. Myofascial pain syndrome is a common painful muscle disorder characterized by […]
Tuberculosis of Spine Presentation and Treatment
Tuberculosis of spine or TB spine or spinal TB was first described by Percivall Pott, after whom it is also referred to as Pott’s disease or Pott’s spine. Tuberculosis of spine is the commonest form of skeletal tuberculosis. It constitutes about 50 percent of all cases of bone and joint TB. There are few other […]
Posture and Postural Defects of Spine
Posture can be defined as the relationship of the parts of the body to the line of the center of gravity. The posture is a gauge of the mechanical efficiency of the neuromusculoskeletal system in the erect position. A normal person may have different postures of standing and sitting. These unusual postures can over time […]
Bone Destruction- Patterns and Their Significance
Different patterns of bone destruction as observed on x-rays are caused by a variety of disease processes affecting the bone. Different types of destructions suggest the intensity and aggression of the disease process. Classically, x-rays were used for imaging and diagnosis. With the advent of CT and MRI, the x-ray diagnosis of lesions has lost […]
Fracture Healing Stages, Types and Factors Affecting Bone Repair
Fracture healing in a broken bone is quite a complex process that begins by hematoma formation, a collection of inflammatory agents that render the bone-forming cells to form bone tissue to bridge the defect created by fracture. In this article, we would discuss steps of fracture healing in a broken bone, the types of fracture […]
