Artificial Cervical Disk Replacement for the Treatment of Adjacent Segment Disease After Anterior Cervical Decompression and Fusion.

Study Design: Retrospective study.

Objective: To evaluate the outcome of artificial cervical disk replacement (ACDR) for the treatment of adjacent segment disease (ASD) after anterior cervical decompression and fusion (ACDF).

Summary Of Background Data: ACDF is the useful procedure for degenerative cervical diseases.

Surgical treatment of selected patients with multilevel contiguous thoracolumbar spinal tuberculosis by only posterior instrumentation without any bone fusion.

The retrospective clinical study is to determine the feasibility and efficacy of surgical management of multilevel contiguous thoracolumbar spinal tuberculosis (MCTLST) by only posterior instrumentation without posterior or anterior bone fusion and without anterior fixation in the study of eleven selected cases. Eleven selected cases with MCTLST were treated with combined posterior instrumentation and debridement and/or decompression without any bone fusion. The mean follow-up was 33.

miR-21 promotes human nucleus pulposus cell proliferation through PTEN/AKT signaling.

The precise role of nucleus pulposus cell proliferation in the pathogenesis of intervertebral disc degeneration remains to be elucidated. Recent findings have revealed that microRNAs, a class of small noncoding RNAs, may regulate cell proliferation in many pathological conditions. Here, we showed that miR-21 was significantly upregulated in degenerative nucleus pulposus tissues when compared with nucleus pulposus tissues that were isolated from patients with idiopathic scoliosis and that miR-10b levels were associated with disc degeneration grade.

[Clinical review of thirty-nine cases of ulnar tunnel syndrome].

Objective: To discuss the concept of ulnar tunnel at the wrist, the types, causes, traits of compression, diagnosis, and clinical significance of ulnar tunnel syndrome (UTS).

Methods: Thirty-nine cases diagnosed as having UTS from 1986 were retrospectively reviewed combined with previous relevant literature.

Results: Ulnar tunnel included Guyon's canal, piso-hamate tunnel and hypothenar segment.
