Cloward Laminia Spreader cam/rat. 50mm, 17cm

Clinical Application

Provides controlled lateral separation of the lamina to expose the spinal canal and neural elements during posterior spinal procedures. Commonly used in laminectomy, laminotomy, decompression and other posterior cervical and lumbar exposures, the device enables sustained retraction of bony elements to improve visualization and instrument access while minimizing the need for continuous manual retraction.

Design & Configuration

The cam/ratchet self-retaining mechanism allows incremental opening and secure locking at the desired spread, maintaining consistent retraction without continuous manual force. The 17 cm overall length gives adequate reach for typical posterior spinal corridors, while a 50 mm maximum spread accommodates moderate laminar separation required for many cervical and lumbar procedures. Opposing spreader blades are shaped to engage laminar margins and provide stable purchase during bone retraction and instrument work in the surgical field.
