Child with severe intracranial and cervical spine injuries with bilateral cranial stabilization tongs, an endotracheal tube, an oroogastric tube, and a feeding tube entering via the nose.  From Hunter, 2004    
Occipital strut with posterior cervical plates Cervical spine anterior and posterior fusion   Odontoid screw (nail) fracture fixation with posterior cervical fixation plates and screws
Occipital strut with posterior cervical plates Anterior and posterior cervical spine fusion AP view Anterior and posterior cervical spine fusion lateral view Odontoid screw (nail) fixation with posterior cervical plates and screws
  Young woman with traumatic locked facets at C6-7 and C7 body fracture. A posterior cervical fusion with lateral mass screws (cervical spine) and pedicle screws (thoracic spine) and rods extends from C4 to T2. There is an anterior cervical fusion plate and screws at C6-7 with a intervertebral disk cage at C6-7 and a crosslink at C6.

There is also an anterior cervical fusion plate and screws from C3-6. Patient with rheumatoid arthritis and atlantoaxial (C1-C2) subluxation and generalized cervical spine laxity Postoperative lateral radiograph of the cervical spine. There is fixation of an odontoid base fracture by an odontoid screw and a sublaminar wire between C1 and C2. There are also skin staples and a surgical drain in the posterior aspect of the neck
Odontoid Fracture Fixation
Type III dens fracture Den fracture fixation device for fusion occiput-C2 Dens fracture fixation from occiput to C2 Dens fracture fixation from occiput to C2
47 year-old woman with type III dens fracture treated by occiput-C2 fusion.
Two odontoid screws Cranial (head) tongs  
Odontoid screws Odontoid screws Head tongs AP view Head tongs lateral view
86 year-old woman with C1 posterior ring and type II dens fractures two months earlier treated with two odontoid (dens) screws. Cranial (head) tongs are used to stabilize the head and neck in a patient with a cervical spine fracture. One or more screws penetrate the outer table of the skull on each side. They are connected to each other by horizontal or vertical bars on each side that are attached to an external traction device.  From Hunter, 2004
Cervical spine anterior and posterior fusion with intervertebral bone struts (plugs)   Posterior cervical spine wiring  
Anterior and posterior cervical fusion with bone struts Anterior and posterior cervical fusion with bone struts Posterior spine wiring Posterior cervical spine wiring lateral view
There is an anterior cervical fusion plate that extends from C3 to C7 and posterior lateral mass screws and rods on each side from C3 to C7. Intervertebral bone struts (plugs) are present at the disk spaces from C3 to C6. Posterior cervical wires from C4 to C7 after laminectomy. The lateral view obtained after cervical myelography. From Hunter, 1994

From Hunter, 1994 65 year-old woman with vertebral disk cages at C3-4, C4-5, and C5-6. A previous anterior C4-6 fusion plate has been removed. The disk cages are composed of PEEK, and there is a zero-profile fusion at C3-4.

Reprinted with the permission of Medtronic, Inc. © 2016 There are also posterior screws and connecting rods at C6-T1 on the right and at C6, C7, and T1 on the left. The right and left C6 and left C7 screws are in the lateral masses. The T1 screws are in the pedicles.

53 year-old man with congenital cervical spine fusion and traumatic fracture through fusion mass at C3-7. The spine is stabilized by surgical fusion hardware from the occiput to T2 plus a halo brace. 44 year-old man with C7 vertebral fracture. Posterior figure of 8 wire fixation extends from C4 to C7    
Cervical spine "corpectomy" and fusion   Posterior Spinal Fusion (PSF)
Cervical spine fusion and corpectomy cage at C4-5 Cervical spine fusion and corpectomy cage at C4-5 Posterior spinal fusion AP view Posterior spinal fusion lateral view
Elderly woman with diskitis at C4-5 and adjacent bony destruction by osteomyelitis at C4 and C5. Initial cervical fusion failed. A corpectomy cage was placed at C4-5 with posterior spinal fusion from the occiput to T2. A crosslink is at C6. 57 year-old woman with rheumatoid arthritis and unstable spine. Posterior spinal fusion (PSF) is present from C3 to T2 with lateral mass screws in the cervical spine from C3-6 bilaterally and pedicle screws in the thoracic spine at T1 and T2 on the left.
Dorsal column stimulator, nasogastric tube, and endotracheal tube Nasotracheal and orgogastric tubes Silicone eyeball prostheses Pantopaque in the skull
Neck apparatus Nasotracheal and orogastric tubes Silicone eyeball prosthesis Pantopaque in the skull
Lateral radiograph of the neck shows a recently placed dorsal column stimulator, a nasogastric tube (black *),and an endotracheal tube (white *). The nasotracheal tube is larger and anterior. The orogastric tube is smaller and posterior (arrow). From Hunter, 1994 From Hunter, 1994 From Hunter, 1994
Vagus nerve stimulator   Esophageal temperature probe Lumboperitoneal shunt
Vagus nerve stimulator AP view Vagus nerve stimulator lateral view Esophageal temperature probe Lumboperitoneal shunt
A left vagus nerve stimulator was placed to treat intractable epilepsy.  From Hunter, 2004 Also shown is an anterior cervical spine fusion plate, a monitoring electrode over an ear, and a dental bridge. From Hunter, 2004 45 year-old woman with two lumboperitoneal shunts to treat pseudotumor cerebri. The inferior shunt tip is at the L4-5 level (lower arrowheads). The superior shunt (upper arrowheads) goes into the thoracic region with its tip not pictured. From Hunter, 2004
Bilateral vagus nerve stimulators   Dorsal column stimulation unit in upper cervical spine  
Bilateral vagus nerve stimulators Bilateral vagus nerve stimulators Dorsal column stimulator in cervical spine Dorsal column stimulator in thoracic spine
62 year-old man with anterior cervical fusion plate and screws C5-7 for treatment of prior cervical spine trauma. Bilateral vagus nerve stimulators were placed to treat chronic syncope.   From Hunter, 2004
