There is a vertebral cage and side plate and screws in the lower thoracic spine for treatment of a spinal tumor.  From Hunter, 1994 From Hunter, 2004
Vertebral compression fracture treated by expandable corpectomy device TLSO brace (Boston brace)

  There are also bilateral pedicle screws and connecting rods above and below the level of the fracture. The brace stabilizes an L1 compression fracture.  
Anterior lumbar interbody fusion (ALIF) Pedicle fixation screws and rods
ALIF L5-S1 ALIF L5-S1 T12-L2 fixation T12-L2 fixation
47 year-old woman with anterior lumbar interbody fusion (ALIF) at L5-S1. 20 year-old woman with L1 vertebral body compression fracture treated with T12-L2 posterior spinal fusion using pedicle screws at T12 and L2 with connecting rods on each side.
Anterior lumbar interbody fusion (ALIF) ILIF: interlaminar lumbar instrument fusion
ALIF at L5-S1 ALIF at L5-S1 ILIF ILIF
60 year-old man with L5-S1 anterior diskectomy and interbody fusion with zero-profile fixation screws at L5-S1. There are PEEK interbody disk grafts at multiple levels from XLIF prior surgery at L2-3 to L4-5. 67 year-old woman with L3-4-5 ILIF. There are partial laminectomies at L3 and L4. Posterior L3-5 stabilization is obtained with a spinous process clamp. There is also posterior L3-5 arthrodesis using structural allograft. The patient is wearing a TLSO brace.

Posterior Instrumented Lumbar fusion (PLIF) X-stop device
PLIF device PLIF AP PLIF lateral view X-stop device
Screws are placed through the pedicles into the vertebral bodies. The screws are connected together on each side with rods or a plate placed over the pedicle screws on each side. Some of these systems are also combined with posterolateral bony fusion masses. Image from rheumatology network
Steffee Plates - Posterior Instrumented Lumbar Fusion (PLIF) Coflex device

There is also a Brantigan disk cage at L5-S1 (arrow on lateral view) The Coflex device is made from titanium. The "U" shaped device is positioned horizontally with its apex anterior. The two long arms of the "U" parallel the long axis of the spinous process. The ridges help keep the device stably attached to the spinous process. Image from Paradigm Spine

PEEK cages packed with iliac crest autograft material in anterior lumbar instrumented fusion (ALIF) with posterior spinal fusion (PSF) at L5-S1
PSF failure ALIF and PSF revision AP view ALIF with PSF revision lateral view Sovereign system
48-year old man with L5-S1 laminectomy and posterior spinal fusion (PSF) for radiculopathy and isthmic spondylolisthesis. There was hardware failure. A subsequent ALIF with a Sovereign cage device (Medtronic) was performed as well as revision of the PSF at L5-S1. Image in the fourth column Reprinted with the permission of Medtronic, Inc. © 2016
Occiput-T8 posterior fusion with anterior cervical fusion from C6-T1.
Occiput-T8 fusion Occiput-T8 fusion Occiput-T8 fusion Occiput-T8 fusion
59 year-old man with occiput to T8 posterior fusion. There is anterior cervical fusion from C6-T1. PEEK disk cages are present at C6-7 and C7-T1. An old compression fracture is present at T5. In the cervical spine lateral mass screws are at C3-6 bilaterally. In the thoracic spine pedicle screws are at T1-3 and T6-8 on the right and at T1-4 and T6-8 on the left. Laminectomies have been performed from C3 to C6.
