DIPLOMAT® Deformity

Treatment of spinal deformities

DIPLOMAT Rod/Screw System - Infralaminar Hooks LSZ

Infralaminar hooks (LSZ) are a sensible alternative to pedicle screws for specific spinal sections. Their stability is comparable to that of pedicle screws.

The advantages of treating deformities using the hybrid technique

Dorsal systems with transpedicular screws as the basic element to stabilise the spine have become the gold standard for surgical treatment of spinal deformities and are used in most cases where correction of scoliosis or segmental fixation is required.
If, however, there is a severe kyphotic or scoliotic spinal deformity, particularly one that is associated with a developmental disorder such as hypoplasia or aplasia of the pedicle that makes insertion of a screw more difficult, this raises the question of other fixation methods.

Additional advantages

  • Improved anchorage for hypoplastic pedicles on the concave side
  • Transfer of force for translation
  • Extension of the dorsal spine; consequently greater control of the sagittal profile
  • Lower implant density with no correction compromises

Product-specific advantages

  • Hook-based System
    • Secure positioning of the implants
  • Secure anchorage
    • Fixation of the hooks to the lamina
    • Force distribution across a number of anchors is possible
  • Surgery less traumatic
    • Reduced surgery time compared to systems based on pedicle screws
    • Reduced blood loss compared to treatment with pedicle screws
  • Safe and straightforward correction
    • Slow, continuous correction
  • Low radiation exposure
    • No need for intraoperative X-rays
  • Color-coding
    • Clearly identifiable implants and instrument selection
  • Straightforward tools
    • A small set of self-explanatory instruments
  • Titanium alloy TiAl6V4
    • Established biocompatible material
  • Opportunity for revision
    • Pedicle and vertebral body remain intact

Indications

DIPLOMAT

The system is indicated for stabilisation of the spine until solid spinal fusion is achieved in patients with:

  • Instability or malposition of the spine
  • Fractures
  • Postoperative or degenerative instability
  • Tumours and spondylodiscitis
  • Spondylolisthesis
  • Disc prolapse
  • Stenosis of the lumbar spine
  • Disc resection
  • Pathological lordosis/kyphosis/scoliosis
  • Degenerative segmental disease
  • Osteoporosis
  • Bone tumours (metastatic or primary)
  • Revision surgery
  • Rheumatic diseases with associated poor bone density/quality

The system is furthermore indicated in situations where external immobilisation by means of a plaster cast or splint is not possible.

LSZ3

The system is indicated for stabilisation of the thoracic/lumbar spine (T„–L–) in patients until solid fusion of the spine has been achieved after surgery:

  • Instability or malposition of the spine
  • Fractures
  • Postoperative or degenerative instability
  • Tumours and spondylodiscitis
  • Correction of Meyerding grade ‰ spondylolisthesis
  • Disc prolapse
  • Stenosis of the lumbar spine
  • Disc resection
  • Pathological lordosis/kyphosis/scoliosis
  • Degenerative segmental disease
