Q&А
Q1: What is the primary function of the Micrometric Swivelling Clamp in an LRS system?
A1: Its primary function is to provide a stable yet adjustable connection between the orthopedic wires or half-pins and the main Linear Rail System (LRS) rod. З “swivelling” capability allows surgeons to position pins at various, often compound, angles to achieve optimal bone purchase and construct stability, which is crucial for complex deformity corrections and limb lengtheningQ2: How does the “micrometric” feature benefit the surgical procedure and patient outcome?
Q2: What’s the advantage of the Micrometric Swivelling Clamp For LRS?
A2: The micrometric (fine-scale measurement) adjustment allows for extremely precise, incremental changes in the pin’s position and orientation. This is critical for achieving perfect fracture reduction, fine-tuning the alignment of bone segments, or making accurate daily adjustments during the distraction phase of limb lengthening, leading to better final outcomes.
Q3: Why is the swivelling function important?
A3: The swivelling design allows multi-directional angulation of the pins relative to the rail, enabling accurate alignment with the bone’s anatomical axis and easier correction of deformities.
Q4: How does it improve surgical precision compared to standard clamps?
A4: The micrometric mechanism allows gradual, repeatable adjustments in small increments, reducing the risk of over-correction or instability during bone distraction.
Q5: Can this clamp be used with both Schanz pins and smooth wires (Olive wires)?
A5: This depends on the specific clamp design. Many modern swiveling clamps are versatile and feature different collets or chucks that can accommodate both Schanz pins (half-pins) and smooth or Olive wires. The surgeon must select the correct chuck for the specific pin/wire type being used.
Q6: What types of bone procedures is this specific clamp most commonly used for?
A6: It is essential for complex procedures requiring multi-planar control, such as:
Limb Lengthening: Precisely controlling the distraction rate and axis.
Deformity Correction: Correcting angular, rotational, and translational deformities simultaneously.
Non-Union Treatment: Providing rigid, multi-directional stability for compromised bone healing.
Reconstruction after Trauma or Tumor Resection: Allowing for customized fixation in compromised bone stock.
Q7: Can surgeons adjust the clamp postoperatively?
A7: Yes, the clamp allows controlled postoperative fine-tuning without removing the fixator, enabling real-time correction of alignment or distraction rate.
Q8: How does this advanced clamp compare to a standard, fixed clamp in terms of cost and complexity?
A8: The micrometric swiveling clamp is significantly more complex in design and manufacturing, making it more expensive than a standard fixed clamp. It also adds a layer of complexity to the surgical procedure, requiring a deeper understanding of frame biomechanics and a meticulous technique for tightening. Однак, the benefit is unparalleled intra-operative flexibility and post-operative adjustability.
Q9: How should the Micrometric Swivelling Clamp be maintained and sterilized?
A9: It should be cleaned and lubricated regularly, then sterilized by autoclaving before each use. The micrometric threads must remain free of debris to ensure smooth adjustment.
