BACKGROUND Selective lumbar nerve root block (SNRB) is generally accepted as an effective treatment method for back pain with sciatica. However, it requires devices producing radioactive materials such as C-arm fluoroscopy. This study evaluated the usefulness of the longitudinal view of transverse process and needles for medial branch block as landmarks under ultrasonography. METHODS We perfo...

BACKGROUND A thorough understanding of the biomechanical characteristics of the healthy human spine is critical in furthering the treatment of spinal pathology. The goal of this study was to investigate the motion of the intact lumbar spine segment as measured by range of motion (ROM), and to investigate the dependencies thereof on gender and intervertebral level. MATERIALS AND METHODS Kinema...

Background: Although transient bone loss has been described during and immediately after pregnancy and lactation, the association between breastfeeding and bone mineral density (BMD) after menopause remains controversial. Objective: To assess the association between breastfeeding and BMD in postmenopausal women in a population-based study. Materials and Methods: We randomly selected 245 healthy...

STUDY DESIGN A study using an anatomically accurate finite-element model of a L2-L3 motion segment to investigate the biomechanical effects of graded bilateral and unilateral facetectomies of L3 under flexion and extension loadings. OBJECTIVE To predict the amount of facetectomy on lumbar motion segment that would cause segmental instability, therefore enhancing the understanding concerning t...

Introduction: Recognition of conus medullaris position, contains lumbosacral plexuses which supply motor and sensory innervation to the whole lower limb, pelvic perineal areas, is critical avoid injury due lumbar procedures, such as spinal anesthesia punctures. This study aimed investigate position among Indonesians through magnetic resonance imaging (MRI) spine at Dr. Soetomo General Academic ...

STUDY DESIGN Prospective study of 212 patients with groin pain but without low back pain. OBJECTIVE To evaluate discogenic groin pain without low back pain or radicular pain. SUMMARY OF BACKGROUND DATA Patients feel low back pain originating from discogenic disease. It has been reported that the rat lower lumbar discs are innervated mainly by L2 dorsal root ganglion neurons. Thus, it is pos...

STUDY DESIGN Case-control. PURPOSE To determine whether a disproportion between two neighboring vertebral end plates is associated with degenerative disc disease. OVERVIEW OF LITERATURE Recently, it has been suggested that disproportion of the end plates of two adjacent vertebrae may increase the risk of disc herniation. METHODS Magnetic resonance (MR) images (n=160) with evidence of grad...

We describe a case of acute lumbar epidural hematoma at the L2-3 level complicated by paraplegia, which occurred after coagulation disorder because of massive bleeding intraoperatively in cesarean section. The preoperative coagulation laboratory finding was in normal range and so we tried combined spinal epidural anesthesia. Uterine atony occurred in the operation, and there was persistant blee...

Dorsal root ganglion neurones with dichotomising axons are present in several species and are considered to play a role in referred pain. Clinically, patients with lesions in the lower lumbar discs occasionally complain of pain in the groin. We investigated the existence of dichotomising afferent neurones projecting axons both to the lumbar disc and to the groin skin, using the double fluoresce...

We conducted a survey of 111 healthy middle-aged and older women, aged 40 to 80 years, to elucidate the relationships between blood leptin and adiponectin levels and bone mineral density (BMD) in September 2008. We examined the associations between the blood levels of these adipocytokines and the lumbar spine (L2-L4), left femoral, and distal forearm BMD after adjustment for the age and body fa...
