This study evaluates the short-term clinical outcome, radiological, histological and device retrieval findings of two patients with second generation lumbar total disc replacement (TDR). ⋯ Although wear was unrelated to the reason for revision, this study demonstrates the presence of UHMWPE particles and inflammatory cells in second generation TDR. Long-term follow-up after TDR is indicated for monitoring wear and implant status.

Case Reports
Congenital kypho-scoliosis: a case of thoracic insufficiency syndrome and the limitations of treatment.
Congenital spinal vertebral anomalies may present with deformity resulting in congenital scoliosis and kyphosis. This leads to abnormal spinal growth. The latter when combined with associated rib fusions may impair normal thoracic cage development and resultant pulmonary hypoplasia. Most congenital scoliosis can be detected in utero by ultrasound scan or recognized in the neonatal period, but a few spinal defects can remain undetected. ⋯ This article highlights the features of congenital kypho-scoliosis and TIS. The difficulties of treating kyphosis when combined with TIS are discussed together with the limitations of current surgical techniques.

Comparative Study
An in vitro biomechanical comparison of Cadisc™-L with natural lumbar discs in axial compression and sagittal flexion.
The elastomeric, monobloc disc prosthesis (Cadisc™-L, Ranier Technology, Cambridge, UK) aims to preserve biomechanics of an implanted spinal motion segment. ⋯ Implantation of Cadisc™-L caused a reduction in axial stiffness, but maintained disc height and flexion stiffness. IAR loci remained mobile without large displacement of the centroid from the intact spine position.

We hypothesized that L5-S1 kinematics will not be affected by the lordosis distribution between the prosthesis endplates. ⋯ Further clinical and biomechanical studies are needed to assess the long-term impact of lordosis angle distribution on the fate of the facet joints.

Case Reports
Chronic pure radiculopathy in patient with organizing epidural hematoma around C8 nerve root.
Spontaneously occurring spinal epidural hematomas are uncommon clinical findings, and the chronic form is the rarest and its most frequent location is the lumbar spine. Pure radicular involvement is far less frequent than myelopathy. We report a case of progressive radiculopathy in a 52-year-old man with spontaneously occurring cervical epidural hematoma (SCEH). ⋯ MRI scan showed small space-occupying lesion around left 8th cervical nerve root. After surgery we confirmed chronic organizing epidural hematoma. To the best of our knowledge, this is the second reported case in the worldwide literature of pure radiculopathy in a patient with chronic SCEH.
