Late Implant Failure in Cervical Disc Arthroplasty (M6-C, Spinal Kinetics) Causing Radiculopathy and Myelopathy.

Cervical disc arthroplasty (CDA) is an approved surgical treatment option in selected patients with cervical spinal disc degeneration. Even though CDA is a standard procedure since 20 years, there is a lack of information about long term performance. The published reoperation rates after CDA are low and comparable to anterior cervical fusion.

[Minimally invasive transforaminal lumbar interbody fusion].

Objective: Instrumented fusion of lumbar motion segments using a minimally invasive technique.

Indications: Degenerative disc disease, segmental degeneration, degenerative spondylolisthesis, isthmic spondylolisthesis, pseudarthrosis, other spinal lumbar instabilities, disc prolapse, revision for failed back surgery syndrome, unilateral neuroforaminal stenosis, facet joint arthrosis.

Contraindications: High-grade spondylolisthesis (Meyerding grades III/IV, spondyloptosis), bilateral nerve root compression, vertebral fractures, tumors, high-grade spinal instabilities, primary spinal deformities, multilevel pathologies.

Transoral Spine Surgery - an Update.

Even though in recent years the number of transoral spinal interventions has decreased in Europe and North America - mainly because of the progress in the drug therapy of rheumatism, there are still pathologies that can only be addressed by a transoral approach. The classical transoral approach can be expanded in collaboration with oral-maxillofacial surgery and ear, nose and throat surgery, but this is rarely necessary. The transoral approach is now mainly used for resection of pathological tissue.

Staged surgical treatment for infection of total disc arthroplasty: three cases and a narrative review of the literature.

Although total disc arthroplasty (TDA) is a common procedure for selected cases of degenerative disc disease, until today there are only two cases of TDA infections reported in the literature. We report three cases of postoperative TDA infections, two developed cutaneous fistulas. To eradicate the infectious site, a staged removal of the device, resolute debridement, and stabilization plus fusion is proposed.
