The Markham-Meyerding Hemilaminextomy Retractor is a 17 cm self-retaining spinal instrument designed for unilateral paraspinal muscle and spinous process displacement during hemilaminectomy. Featuring an asymmetrical 63.5 mm × 25 mm blade paired with an opposing single hook in Left or Right layouts, it maintains rigid hands-free exposure.
Product Description
The Markham-Meyerding Hemilaminextomy Retractor is a specialized spinal surgical retractor engineered specifically to establish and maintain an unyielding unilateral operative window during posterior lumbar hemilaminectomy and discectomy. Designed with an asymmetrical working framework, this retractor anchors against the spinous process while simultaneously retracting heavy paraspinal musculature laterally away from the laminar corridor.
Built to clinical framework specifications, this Markham-Meyerding Hemilaminextomy Retractor retains a fixed overall length of 17 cm ($124) while offering two mirrored anatomical layouts selectable via the purchase configuration menu. Option 1 features a 63.5 mm long × 25 mm wide blade on the left side paired with a single hook on the right side, while Option 2 places the blade on the right side paired with a left hook. Its multi-position mechanical ratchet lock sustains continuous counter-traction automatically, eliminating assistant hand fatigue throughout deep canal decompression.
Handcrafted from premium operating room-grade German stainless steel with a reflection-free satin matte finish, Retractor Maker manufactures the Markham-Meyerding Hemilaminextomy Retractor to withstand repetitive hospital autoclave cycles, providing spine centers, neurosurgical suites, and orthopedic trauma units worldwide with unyielding structural rigidity, high corrosion resistance, and complete clinical durability.

Frequently Asked Questions
What are the blade and handle design advantages of the Markham-Meyerding Hemilaminextomy Retractor?
The Markham-Meyerding Hemilaminextomy Retractor is a solid one-piece instrument, so its performance comes from blade geometry and handle ergonomics. The working blade is specified as 63.5 mm long × 25 mm wide blade paired with an opposing single hook, which spreads retraction force over a wider contact area and reduces point pressure on tissue. An overall length of 17 cm (approx. 6.7 inches) keeps the surgeon's hand clear of the operative field. It is made from premium operating room-grade german stainless steel (aisi 304/420) for glare-free, corrosion-resistant service.
What is the Markham-Meyerding Hemilaminextomy Retractor used for?
The Markham-Meyerding Hemilaminextomy Retractor is used in spine surgery to anchor on the spinous process with its hook while retracting the paraspinal muscles with its blade, providing hands-free access to the lamina.
Which surgical procedures is it for?
It is indicated for lumbar hemilaminectomy, microdiscectomy, unilateral laminotomy, lateral recess decompression, and posterior spinal root neurolysis.
What material and finish are used?
The instrument is handcrafted from premium German surgical stainless steel with an anti-glare satin matte finish that eliminates optical reflections under surgical operating microscopes and headlights.
Is the Markham-Meyerding Hemilaminextomy Retractor reusable and autoclavable?
Yes. The entire Markham-Meyerding Hemilaminextomy Retractor is 100% reusable and fully validated for pre-vacuum steam autoclave cycles (134°C / 273°F). The ratchet teeth and hinge pivot should be lubricated regularly.
Can components and blades be ordered separately?
Because this is an integrated mechanical retractor, each mirrored layout is sold as a standalone unit. Hospitals typically order paired sets (Options 1 and 2) to equip spine trays.
Can custom modifications or private-label markings be ordered?
Yes. Retractor Maker provides custom blade depths, modified hook curvatures, and laser marking for hospital asset tracking upon request.
What is the standard lead time and delivery timeframe for orders?
In-stock instruments take 5 business days to inspect and dispatch, followed by 7 business days for worldwide express delivery. Back-order units take 17 to 20 business days to manufacture and 9 business days for delivery.
