SQUARE CONNECTOR
A square connector is a type of orthopedic implant used in various surgical procedures, particularly in spinal fusion surgeries. Here's an overview of its specifications and uses:
Specification
- Material: Square connectors are typically made from medical-grade titanium or titanium alloy. This material is chosen for its biocompatibility, strength, and durability, ensuring compatibility with bone tissue and long-term stability within the spinal construct.
- Shape: Square connectors have a square or rectangular shape, with four sides of equal length meeting at right angles. This shape provides stability and prevents rotation of the connected components, such as rods or plates, within the spinal instrumentation system.
- Dimensions: The dimensions of the square connector may vary depending on the specific surgical technique and the size of the spinal anatomy being instrumented. Common dimensions include the length of each side of the square and the thickness of the connector.
- Attachment Points: Square connectors feature attachment points on each side of the square, allowing for the secure connection of spinal rods, plates, or other instrumentation components. These attachment points may include set screws, locking caps, or compression mechanisms to ensure a stable and rigid construct.
- Surface Texture: The surface of the square connector may be textured or coated to enhance grip and stability within the connected components. Textured surfaces or coatings can help prevent loosening or migration of the connector within the instrumentation system, ensuring long-term stability of the spinal construct.
Uses
- Spinal Fusion Surgery: Square connectors are primarily used in spinal fusion surgeries to provide stabilization and instrumentation of the spine. They serve as a rigid framework to support the vertebral segments and promote fusion of the adjacent vertebrae.
- Correction of Spinal Deformities: These connectors may be used in the correction of spinal deformities such as scoliosis, kyphosis, or spondylolisthesis. By connecting spinal rods or plates at right angles, square connectors help to realign the spine to a more anatomically correct position.
- Trauma Surgery: Square connectors can be employed in the treatment of traumatic spinal injuries, such as fractures or dislocations. They provide additional stability and support to the injured spinal segments, aiding in fracture reduction and promoting healing.
- Revision Surgery: Square connectors may be used in revision spinal surgeries to augment or replace existing instrumentation. They can provide additional stability and support in cases where previous instrumentation has failed or requires modification.
- Minimally Invasive Surgery: In minimally invasive spinal surgeries, square connectors with a low-profile design are used to minimize tissue disruption and facilitate less invasive approaches. They allow for stabilization of the spinal instrumentation system while preserving adjacent anatomical structures.
In summary, square connectors are valuable instruments in spinal surgery, offering stability, rigidity, and versatility in various surgical procedures. They are utilized by trained spinal surgeons following proper surgical techniques and patient-specific considerations to achieve successful fusion and stabilization of the spine.
