In Brief Study Design. A comparative analysis of paraspinal muscle damage and radiographic parameters after mini-open conventional open posterior lumbar interbody fusion (PLIF). Objective. To determine whether PLIF decreases yields the same results as those in PLIF. Summary Background Data. Compared with PLIF, using a paramedian approach reduces intraoperative hemorrhage postoperative back pain. However, latter produces less than former remains unclear. No study has investigated slip...

A prospective randomized comparative study.To evaluate the effect of tranexamic acid (TXA) on decreasing perioperative blood loss in cervical laminoplasty, which surgical procedure is identical all cases.TXA, an inhibitor fibrinolysis, has proven to be effective reducing patients undergoing total hip and knee arthroplasty. However, only a limited number well-controlled spinal surgery trials have been conducted due heterogeneity performed procedures.Forty consecutive with compressive...

STUDY DESIGN.: Prospective cohort study. OBJECTIVE.: To investigate the recovery process after laminoplasty in patients with cervical myelopathy, and effects of patient age duration symptoms before surgery on process. SUMMARY OF BACKGROUND DATA.: The surgical results for myelopathy have been well documented, but there few reports laminoplasty. METHODS.: study group consisted 98 who underwent double-door myelopathy. All cases were followed a minimum 5 years. JOA score, 10 seconds grip release...

Little information is available about the incidence and outcome of incidental dural tears associated with microendoscopic lumbar decompressive surgery. We prospectively examined their influence on six months post-operatively in 555 consecutive patients (mean age 47.4 years (13 to 89)) who underwent this form The was 5.05% (28/555). risk factors were patient procedure bilateral decompression via a unilateral approach. rate recovery Japanese Orthopaedic Association score significantly lower...

We retrospectively examined the prevalence and natural history of asymptomatic lumbar canal stenosis in patients treated surgically for cervical compressive myelopathy order to assess influence latent on recovery after surgery. Of 214 who had undergone laminoplasty myelopathy, we identified 69 (32%) with myelographically documented stenosis. these, 28 (13%) symptomatic underwent simultaneous decompression. remaining 41 (19%) only surgery, 39 were followed up ≥ 1 year (mean 4.9 years (1 12))...

We investigated the effects of instrumentation on postoperative inflammatory reaction and identified standard changes in serum cytokine concentrations after spinal surgery. Pro-inflammatory cytokines [interleukin (IL)-6 IL-8] anti-inflammatory [IL-10, IL-1 receptor antagonist (ra), soluble tumor necrosis factor receptors (sTNF-R) I II] were assayed from seven patients with lumbar posterior decompression, six decompression posterolateral fusion without instrumentation. All increased...

Study Design. Retrospective case series. Objective. To determine relevant demographics, clinical presentations, and outcomes of surgical site infections (SSIs) after spinal instrumentation (SI) surgery caused by methicillin-resistant Staphylococcus epidermidis (MRSE). Summary Background Data. This is the first study looking specifically at MRSE-related SSIs SI surgery. Methods. We performed a retrospective review patients with from 665 consecutive cases between 2007 2014 our institution....

Retrospective analysis.To test the hypothesis that preoperative spinal cord damage affects postoperative segmental motor paralysis (SMP).SMP is an enigmatic complication after cervical decompression surgery. The cause of this remains controversial. We particularly focused on T2-weighted high signal change (T2HSC) magnetic resonance imaging in cord, and assessed influence T2HSC SMP surgery.A retrospective review 181 consecutive patients (130 males 51 females) who underwent surgery was...

We studied embryological development of the human spinal ligaments by dissecting 25 fetuses that ranged from 6 to 24 weeks gestational age. At and 7 weeks, spine consisted light zones dark zones. The were hypocellular corresponded vertebral bodies. hypercellular intervertebral disks. anterior longitudinal ligament was identified at age 8 weeks. 10 posterior detected. 12 laminae, ligamentum flavum, an ossification center identified. 15 fibers flavum became clearer, but they not as well...

Background The World Health Organization has set a goal of hepatitis C virus (HCV) elimination by the year 2030. However, no regions in Japan have succeeded eradicating HCV. Micro-elimination is an approach to attain eradication which national goals are applied specific populations so that viral treatment and control efforts can move forward quickly efficiently. In order eradicate HCV from Japan, this study aims achieve micro-elimination town Nagawa. Methods design Nagawa Project ongoing,...

In recent years, lateral lumbar interbody fusion (LLIF), performed as extreme (XLIF) and oblique (OLIF), has also become widely used for anterior-posterior corrective fusion. However, there are few detailed reports comparing techniques in the treatment of two-level degenerative spondylolisthesis. We compared surgical invasiveness postoperative outcomes between posterior with (PLIF) or transforaminal (TLIF) LLIF Fifteen patients underwent PLIF TLIF at 2 vertebral intervals (posterior group) 8...
