Clinical and radiologic comparison of anterior-posterior single-position lateral surgery versus MIS-TLIF for degenerative lumbar spondylolisthesis.

Background: The lateral interbody fusion (LIF) has gained popularity for the surgical treatment of lumbar degenerative spondylolisthesis (DS), however, LIF often requires the position change for posterior screwing. We have performed the single-position lateral surgery of oblique lateral interbody fusion (OLIF) and posterior screwing (OLIF-LPF). The present study compared the clinical and radiologic results between OLIF-LPF and minimally invasive transforaminal interbody fusion (MIS-TLIF).

Single-level controlled comparison of OLIF51 and percutaneous screw in lateral position versus MIS-TLIF for lumbosacral degenerative disorders: Clinical and radiologic study.

Background: We have performed minimally invasive Oblique Lateral Interbody Fusion at L5/S1 (OLIF51) and simultaneous posterior screwing in lateral position for lumbosacral disorders. This study compared the clinical and radiologic results between OLIF51 versus Minimally Invasive Transforaminal Lumbar Interbody Fusion (MIS-TLIF) in single-level fusion for lumbosacral degenerative disorders.

Methods: A total of 71 patients underwent either OLIF51 (33 cases) or MIS-TLIF (38 cases) at L5/S1 spinal segment.

Comparison between component designs with different femoral head size in metal-on-metal total hip arthroplasty; multicenter randomized prospective study.

Backgrounds/aims: We prospectively studied 78 prostheses with conventional femoral head and 86 prostheses with large head (Magnum) of metal-on-metal total hip arthroplasty (MoM THA) with two years follow-up.

Methods: Clinical outcomes and blood metal ion were evaluated.

Results: There were no significant differences of clinical outcomes between groups.

A case of thrombotic thrombocytopenic purpura induced by acute pancreatitis.

Thrombotic thrombocytopenic purpura (TTP) is a multisystemic microvascular disorder that may be caused by an imbalance between unusually large von Willebrand factor multimers and the cleaving protease ADAMTS13. In acquired TTP, especially in secondary TTP with various underlying diseases, the diagnosis is difficult because there are many cases that do not exhibit severe deficiency of ADAMTS13 or raised levels of ADAMST13 inhibitors. It is well known that collagen disease, malignancy, and hematopoietic stem cell transplantation can be underlying conditions that induce TTP.
