How to find the right Surgical Distraction Screws AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Surgical Distraction Screws
- System match
- Buy pins only from the same manufacturer and system as your distractor, for example the Caspar-type cervical distractor. The thread pitch, hex and pin diameter are system-specific, so a mismatched pin can slip or strip under load.
- Length
- Choose a pin length that suits the depth of the vertebral body, checked on imaging. A pin that is too long risks breaching the posterior cortex. A pin that is too short pulls out under distraction.
- Sterile supply
- Buy sterile-packed pins, or reusable pins with documented reprocessing instructions. These are implanted temporarily in bone, so traceability matters.
- Thread condition
- Discard reusable pins with dulled or damaged threads. Worn threads lose purchase, especially in osteoporotic bone.
Brands that matter
- Aesculap: Long associated with Caspar cervical distraction instruments.
- Medtronic: Supplies distraction pins within its spine systems.
- DePuy Synthes: Supplies distraction pins within its spine systems.
What to avoid
- Generic 'compatible' pins with no stated system compatibility.
- Mixing pins and distractor bodies from different vendors.
