I.What are the different types of external fixation?
External fixation is an instrument attached to the bones of arm,leg or foot with threaded pins and wires. These threaded pins and wires pass through skin and muscles and are inserted into the bone.The majority of devices are outside of the body,so it’s called external fixation.It typically includes the following types:
1. Unilateral nondetachble external fixation system.
2. Modular fixation system.
3. Ring fixation system.
Both types of externalfixators can be hinged to allow the elbow, hip, knee or ankle joint to move during treatment.
• Unilateral nondetachble external fixation system have a straight bar that is placed on one side of the arm, leg or foot. It is connected to the bone by screws that are often coated with hydroxyapatite to improve the screws’“hold” in the bone and prevent loosening. The patient (or family member) may need to adjust the device several times a day by turning knobs.
• Modular fixation system is composed of a variety of components, including needle-rod connection clamps, rod-rod connection clamps, carbon fiber connecting rods, bone traction needles, ring-rod connectors, rings, adjustable connecting rods, needle-ring connectors, steel needles, etc. These components can be flexibly combined according to the specific conditions of the patient to form different fixation configurations.
• Ring fixation system can completely or partially encircle the arm, leg or foot that is being treated. These fxators are made up of two or more circular rings that are connected by struts, wires or pins.
What are the three stages of fracture treatment?
The three stages of fracture treatment - first aid, reduction and fixation, and recovery - are interconnected and indispensable. First aid creates conditions for next treatment, reduction and fixation is the key of treatment, and recovery is important to restoring function.Throughout the treatment process, doctors, nurses, rehabilitation therapists and patients need to work closely together to promote fracture healing and functional recovery.
The fixation methods include internal fixation, external fixation and plaster fixation.
1. Internal fixation uses plates, screws, intramedullary nails and other instruments to fix the fracture ends internally. Internal fixation is suitable for patients who early weight bearing is required or high fracture stability is required.
2. External fixation need an external fixator to fix the fracture ends externally. External fixation applys for open fractures, fractures with severe soft tissue damage, or cases where soft tissue needs to be protected.
3. Casting immobilizes the injured part with a plaster cast. Casting is suitable for simple fractures or as a temporary fixation measure.
- What is the full form of LRS?
LRS is short for Limb reconstruction system , which is a advanded orthopedic external fixator. LRS is aviliable for the treatment of complex fracture, bone defect, discrepancy in leg length, infection, malformation inborn or acquired.
LRS fixes in the right place by installing an external fixator outside the body and using steel pins or screws to go through the bone. These pins or screws are connected to the external fixator, forming a stable support structure to ensure the bone remains stable during the healing or lengthening process.
Feature:
Dynamic Adjustment:
• An important feature of the LRS system is its ability to adjust dynamically. Doctors can modify the configuration of the fixator at any time based on the patient's recovery progress.
• This flexibility allows the LRS to adapt to different treatment requirements and ensures the effectiveness of the treatment.
Rehabilitation Support:
• While stabilizing the bones, the LRS system allows patients to engage in early mobilization and rehabilitation exercises.
• This helps to reduce muscle atrophy and joint stiffness, promoting the recovery of limb function.
