One of the reasons for facet arthrosis after TDR has been speculated to be the hypermobility of artificial discs. Accordingly, the artificial disc that can constrain the hypermobility of ball-and-socket type artificial discs and reduce loading on facet joints is demanded. Read More

Chondrosarcoma arising within synovial chondromatosis of the lumbar spine.

Skeletal Radiol 2019 Sep 5;48(9):1443-1449. Epub 2019 Feb 5.

Department of Radiology and Department of Orthopedics, Mayo Clinic, 200 First Street SW, Rochester, MN, 55905, USA.

Synovial chondromatosis is an uncommon benign neoplasm that usually affects large appendicular joints and only rarely the spine. There are only a few small series and case reports documenting malignant transformation of synovial chondromatosis into secondary chondrosarcoma, typically within the hip in the setting of recalcitrant disease and multiple recurrences. Chondrosarcoma arising in synovial chondromatosis of the spine is exceedingly rare, with only one previously published case report involving the craniocervical junction. Read More

[Lumbar facet joint disease : Classification, clinical diagnostics, and minimally invasive treatment].

Authors:
Florian Faber

Orthopade 2019 Jan;48(1):77-83

Orthopädische Universitätsklinik Regensburg, Asklepios Klinikum Bad Abbach, Universität Regensburg, 93077, Bad Abbach, Deutschland.

Background: The degeneration of the lumbar facet joint is a multi-factorial process that is closely linked to degeneration of the intervertebral discs and has been implicated as one of the causes of low-back pain of elderly patients in about 15 up to 40% of cases. Moreover, emerging data suggest that increased inflammatory features play an important role in the progression of lumbar facet joint disease and may serve as a link to the afferent pain nerve fibers.

Operative Techniques: Since the first description in 1975 of minimally invasive treatment of lumbar facet joint disease, different techniques have been developed and used with varying results. Read More

Tumoral calcinosis of the lumbar and cervical spine.

J Clin Neurosci 2019 Apr 3;62:243-245. Epub 2019 Jan 3.

Department of Neurosurgery, Mayo Clinic, Jacksonville, FL, USA.

Background: Tumoral calcinosis has been defined as a pathological condition which presents as calcified masses around juxta-articular structures. The etiology of this pathology is still not well understood but degenerative spine diseases seem to play a role. The diagnosis of tumoral calcinosis preoperatively can prevent intraoperative confusion from unexpected findings, especially in cases where removal of the calcified mass is essential to treating the patient's symptoms, i.
