Over a period of 25 years, a surgical technique has evolved for removal of a soft disc herniation in patients with sciatica and lumbar stenosis demonstrated on neuroradiological studies. Initially emphasis was placed on decompression of the entire narrow spinal canal when there was evidence of single nerve root involvement and no history of neurogenic claudication. The author has performed 12 microsurgical discectomies since 1984 and eight percutaneous endoscopic discectomies over the past 6 years that have been successful in relieving radiculitis and radiculopathy in cases of a single herniated nucleus pulposus, even in the presence of a stenotic canal. No patient complained of generalized numbness, weakness, or pain in the lower extremities while walking. After at least 1 year of follow up, the 20 patients who underwent microsurgical or arthroscopic procedures limited to removing the ruptured disc have not required more extensive decompression.

Objective: Aim: To investigate the peculiarities of deviations of preoperative values of biochemical markers of inflammation in the blood serum of patients with degenerative diseases of the lumbar spine after transpedicular fixation, with a complicated postoperative course to predict the development of various postoperative complications.
Patients And Methods: Materials and Methods: The content of glycoproteins (GP), sialic acids (SA), C-reactive protein (CRP), seroglicoids (SG), haptoglobin (HG), Veltman`s test (VT) were investigated. The results are comparable by the Student-Fisher method.

Background/context: Chronic low back pain (CLBP) is a significant US healthcare burden with millions of lumbar spine procedures annually. Diagnostic tests are essential to guide treatment but provocative discography (PD), the most common diagnostic procedure, is without robust evidence of its value. A non-invasive alternative using Magnetic Resonance Spectroscopy (MRS) offers a potential solution.

Background: Tropical Candida spondylitis is an uncommon cause of lower back pain in patients, especially in non-tropical areas or in patients not at risk of immunocompromise.
Case Presentation: A 65-year-old woman presented with a six-month history of poorly managed low back pain, now accompanied by numbness and pain in both lower extremities. Her medical history was significant for tertiary hypertension.
Differences of microbial growth and biofilm formation among periprosthetic joint infection-causing species: an animal study.
Int Microbiol
January 2025
Department of Orthopedics and Traumatology, Ankara University School of Medicine, Ankara, Turkey.
Purpose: The most frequently used surgical procedures for periprosthetic joint infections (PJIs) are debridement, antibiotics, and implant retention (DAIR), as well as single- or two-stage revision arthroplasty. The choice of surgery is made depending on the full maturation of the biofilm layer. The purpose of this study was to evaluate the biofilm formation and microbial growth using common PJI-causing agents and compare its development on the implant surface.

Objective: Titanium surface modifications improve osseointegration in dental and orthopedic implants. However, soft tissue cells can also reach the implant surface in immediate loading protocols. While previous research focused on osteogenic cells, the early response of soft tissue cells still needs to be better understood.
