Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
The medical device shares a number of components and features of the Ilizarov apparatus. The Taylor Spatial Frame is a hexapod device based on a Stewart platform, and was invented by orthopaedic surgeon Charles Taylor. The device consists of two or more aluminum or carbon fibre rings connected by six struts. Each strut can be independently ...
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing.

Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
In most cases traction is only one part of the treatment plan of a patient needing such therapy. The physician's order will contain: Type of traction; Amount of weight to be applied; Frequency of neurovascular checks if more frequent than every four hours; Site care of inserted pins, wires, or tongs; The site and care of straps, harnesses and ...
Many definitions of joint manipulation have been proposed. [1] The most rigorous definition, based on available empirical research is that of Evans and Lucas: [2] "Separation (gapping) of opposing articular surfaces of a synovial joint, caused by a force applied perpendicularly to those articular surfaces, that results in cavitation within the synovial fluid of that joint."
An EDF (elongation, derotation, flexion) cast is a specialized orthopedic device used in the treatment of Infantile Idiopathic Scoliosis. This method of correction was pioneered by UK scoliosis specialist Min Mehta and is a non-surgical approach designed to guide spinal growth and alignment during a critical developmental period. [ 3 ]
The corresponding definition for the mechanical response of a manipulation is: "Separation (gapping) of opposing articular surfaces of a synovial joint that results in cavitation within the synovial fluid of that joint." In turn, the action of a manipulation can be defined as: "A force applied perpendicularly to the articular surfaces."
