During the past 25 years, spinal instrumentation systems and surgical techniques used to treat idiopathic scoliosis have evolved, achieving fewer patient restrictions during arthrodesis healing, shorter constructs, and better correction. The purposes of this retrospective comparative study were to determine the survivorship of the implant/fusion without reoperation and the risk factors influencing such survival. ⋯ The most stable lower instrumented vertebra anchor configuration, bilateral pedicle screws, and the stronger transverse connector design, closed drop entry, provided the best survival of the implant/fusion without reoperation with this system and the techniques used at 9-year follow-up. We hope that this post-market study using survivorship techniques will be a guide for studies of other spinal implants.

Even though many clinical reports about cages have been documented in patients with degenerative disorders, reports were scarce for traumatic injury cases, and those cases using metal cages were restricted to only one-level injury. ⋯ The PEEK cage and additional plate fixation is a surgical procedure that decreases donor site morbidity, obtains high fusion rate with rigid fixation, and provides satisfactory clinical outcome for traumatic cervical spine injuries, regardless of the numbers of the involved levels.

The current criterion standard for zygapophyseal (facet) joint pain diagnosis is placebo-controlled triple comparative local anesthetic facet joint or medial branch blocks. Single photon emission computerized tomography (SPECT) scanning is a less invasive modality that has been widely used in patients with spinal pain for the diagnosis of facet joint arthritis. Previous studies have shown that SPECT results correlate well with response to facet joints steroid injections. ⋯ In a hospital-wide population with spinal pain, there is a 42.88% prevalence of increased uptake in the facet joint on SPECT. The incidence increases significantly with advancing age. SPECT can play a role in investigating patients with spinal pain.

Although there have been several studies in which the surgical outcomes were evaluated by pain reduction or neurological improvement, there have been few studies focused on the quality of life (QOL) of the patients after the surgery. We considered that the most important consideration in palliative surgery was to respect the wishes of patients and their families, which are likely to be influenced by the patients' QOL for their limited life span. ⋯ These results strongly suggested that palliative surgery is a valuable treatment for metastatic spinal disease. Younger patients were more likely to want active treatment and to seek any functional improvement that contributed to an improved QOL in their limited life span. Pain control and the length of patient survival were important factors for people caring for patients.

Randomized Controlled Trial
Sex life and sexual function in men and women before and after total disc replacement compared with posterior lumbar fusion.
Sex life and sexual function may be affected by low back pain (LBP). Sexual dysfunction after anterior lumbar fusion is reported in both men and women, but focus is mainly on impaired male biological function (retrograde ejaculation) as this may cause infertility. This has led to concern as to whether anterior surgery should be employed in men, at least in younger age groups. ⋯ Impairment of sex life appears to be related to CLBP. An improvement in sex life after TDR or lumbar fusion was positively correlated to a reduction in LBP. Total disc replacement in this study, performed through an anterior retroperitoneal approach, was not associated with greater sexual dysfunction compared with instrumented lumbar fusion performed either as a PLF or as a PLIF. Sexual function, expressed as orgasm, deteriorated in men in the Fusion group postoperatively, in spite of this group reporting less LBP after 2 years.
