Thoracolumbar Spine Locking Plate (TSLP)

The Thoracolumbar Spine Locking Plate (TSLP) is a versatile, low profile system indicated for use from T1 to L5. The low profile and narrow plate dimensions are advantageous for the mid- to high-thoracic spine. The plates are curved to match the natural kyphosis or lordosis of the spine. The TSLP is available in lengths from 40109 mm and has multiple screw hole locations that enable optimal screw placement for the best bone/screw interface and avoid screw interference in the presence of a 360 degree fusion.


The 1-step 5.5 mm Ti Cancellous Locking Screw locks flush with the top surface of the plate to minimize soft tissue irritation. They are available in 2254 mm lengths.
A special instrumentation has been designed to address the anatomy.


Conical extraction screw
The conical extraction screw is designed for the removal of screws with a damaged 3.5 mm hex recess, eg, with use of the Thoracic Spine Locking Plate (TSLP) or the Anterior Tension Band System. Its length accommodates the depth of anterior thoracolumbar procedures.

Pathology: 68 - year- old male sustained a high energy C-type shear fracture of the L1 vertebra after a fall off of a bridge. The patient had received posterior fixation three weeks before this accident, but still displayed intractable leg pain. The posterior fixation consisted of Dual - Opening USS pedicle screws at T10 -T12 and L2- L3. The preoperative x- rays and MRI showed that the patient had some slippage at the L1- L2 disc and that there were still several pieces of bone impinging on the spinal canal.

Indication: Corpectomy of the L1 vertebral body.
