BACKGROUND: Residual disc fragments are observed on immediate postoperative magnetic resonance imaging (MRI) in 2.8-15% of patients after percutaneous endoscopic lumbar discectomy (PELD). Considering the known postoperative longitudinal outcomes in patients with residual disc tissue, a 'watchful waiting' strategy may be preferable to immediate re-operation in patients with asymptomatic residual disc material. OBJECTIVES: The aim of the present study was to compare the longitudinal clinical outcomes between PELD patients in whom the complete removal of disc fragments was achieved (complete group) and those in whom residual disc fragments were observed on postoperative MRI (residual group)...

BACKGROUND: Glucocorticoids adversely affect bone mineral density (BMD) and increase the risk of fracture. Yet, the cause-and-effect relationship between epidural steroid injection (ESI) and BMD has not been thoroughly investigated, and available results are inconsistent. This is probably a consequence of differences in the dose of steroids and follow-up duration. OBJECTIVE: This study aimed to evaluate changes in BMD and the risk of fracture according to duration of the follow-up and amount of steroids used for ESI...

BACKGROUND: Patients with chronic musculoskeletal pain have a higher chance of presenting impairment in cardiovascular autonomic modulation, which may have implications for cardiovascular events. The autonomic nervous system plays an important role in pain modulation. However, it is unclear whether patients with inefficient descending nociceptive inhibition have poorer cardiovascular autonomic modulation. OBJECTIVE: To compare the cardiovascular autonomic modulation of patients with musculoskeletal pain who had normal versus impaired functioning of descending nociceptive inhibitory system (DNIS)...

BACKGROUND: Lumbar disc herniation (LDH) is being treated with limited indication by percutaneous full endoscopic lumbar discectomy. However, microscopic lumbar discectomy (MLD) is still considered as a gold standard. OBJECTIVE: With the advances in spinal endoscopic instruments and surgical techniques, all LDHs have now become operable with percutaneous full endoscopic lumbar discectomy procedure. We report the results of percutaneous full endoscopic lumbar discectomy (PELD) for all patients diagnosed with LDH, including severely difficult and extremely difficult LDH cases who visited our clinic with leg pain and lower back pain...

BACKGROUND: Although sacroiliac joint dysfunction (SIJD) is generally regarded as a source of lumbar pain, its anatomical position and the absence of a diagnostic 'gold standard' lead to difficulties at examination and differential diagnosis. However, since sacroiliac (SI) joint blocks only provide information about pathologies of joint origin and since SIJD developing secondary to pathologies in structures around the joint can be missed. Provocation and palpation tests also need to be used in diagnosis...

Xin Huang, Bin Zhu, Xiaoguang Liu
BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) has become an increasingly popular minimally invasive spinal surgery. Due to the technical evolution of PELD, the focus of decompression has shifted from the central nucleus to the subannular-protruded disc herniation, which allows direct neural decompression. Surgical entry into the spinal canal leads to the greater possibility of bony structure obstruction, thus the location and direction of the working channel are crucial...

BACKGROUND: Percutaneous transforaminal endoscopic discectomy (PTED) under local anesthesia (LA) is growing popular in recent years because of its safety, effectiveness and increased patient demands for minimally invasive procedures. To avoid neural injuries, local anesthesia that can keep the patient conscious is recommended. However, many patients complain about the severe pain during surgery. Epidural anesthesia (EA) is an alternative choice. We put forward an anesthetic method that combined preemptive analgesia (PA) and local anesthesia...

BACKGROUND: Surgery for thoracic disc herniation and stenosis is comparatively rare and often demanding. The goal is to achieve sufficient decompression without manipulating the spinal cord and to minimize surgical trauma and its consequences. Individual planning and various surgical techniques and approaches are required. The key factors for selecting the technique are anatomical location, consistency of the pathology, general condition of the patient, and the surgeon's experience. OBJECTIVES: The objective of the study was the evaluation of the technical implementation and outcomes of a full-endoscopic uniportal technique via the extraforaminal approach in patients with symptomatic soft or calcified disc herniation of the thoracic spine, taking specific advantages and disadvantages and literature into consideration...

BACKGROUND: Osteoarthritis of the hip joint is a common cause of pain and disability. Patients not responding to conservative management often cannot undergo joint replacement due to the presence of multiple comorbidities, while some other patients prefer to postpone surgery as long as possible. Radiofrequency denervation of articular branches of the femoral and obturator nerves, which supply innervation of the joint, is a novel technique to reduce hip joint pain. Previous studies reported positive results after application of continuous radiofrequency to the target nerves; however, this approach carries the potential risk of neuritis and neuroma formation...

BACKGROUND: Interferon regulatory factor 8 (IRF8), which is induced by peripheral nerve injury (PNI), plays a key role in activating spinal microglia to release inflammatory cytokines in a p38-dependent way, thereafter results in formation of central sensitization. Pulsed radiofrequency (PRF) on dorsal root ganglion (DRG) alleviates neuropathic pain and inhibits the microglial activation in chronic constriction injury (CCI) rats. However, the consequences of PRF on spinal IRF8 of CCI rats remains unknown...

BACKGROUND: Degenerative lumbar spine disease can lead to lumbar spine instability. Lumbar spine instability is defined as an abnormal response to applied loads characterized kinematically by abnormal movement in the motion segment beyond normal constraints. Patients with lumbar spinal stenosis (LSS) typically present with low back pain (LBP), cramping, cauda equine syndrome, and signs of nerve root compression associated by weakness, numbness and tingling in their legs that are worsened with standing and walking...

BACKGROUND: The acute phase of shingles is characterized by severe pain, and one of the complications of shingles known as postherpetic neuralgia (PHN) is associated with prolonged pain. Although factors predicting the development of PHN, as well as its preventative measures, have been investigated, there is no single treatment effective for PHN. Some studies showed effectiveness of epidural injection to alleviate pain associated with acute-phase shingles. In these studies, epidural injection was performed by interlaminar (IL) approach...

BACKGROUND: Understanding analgesic pharmacodynamics (PD) in the elderly is key to optimising pain management. Electrically stimulated pain models (ESPM) permit assessment of pain responses in humans. C and A-delta sensory fibres convey pain and respond to low frequency electrical stimulus (5 and 250 Hz, respectively). Human research suggests pain tolerance threshold (PTT) is similar or decreases with age. OBJECTIVES: To determine whether an ESPM is able to detect a difference in PTT in elderly (>/= 75 years) and young (20-40 years) subjects after single dose administration of a placebo and tramadol, a low potency analgesic...
