Idiopathic thoracic scoliosis with a proximal thoracic curve of more than 25 degrees and level or elevated left shoulder should be considered a double thoracic curve pattern and should be treated by fusing both the proximal and the distal curves when using segmental instrumentation.

Ischiofemoral impingement syndrome is an uncommon disorder defined by hip pain caused by the narrowing of the space between the ischial tuberosity and lesser trochanter with associated entrapment of the quadratus femoris muscle. We effectively treated two male patients using ultrasound-guided prolotherapy with polydeoxyribonucleotide sodium mixed with local anesthetics. A 24-year-old male patient with no history of trauma or surgery complained of bilateral hip and groin pain; magnetic resonance

Metasurfaces consisting of artificially designed meta-atoms have been popularized recently due to their advantages of amplitude and phase of light control. However, the electron beam lithography method for metasurface fabrication has high cost and low throughput, which results in a limitation for the fabrication of metasurfaces. In this study, nanocomposite printing technology is used to fabricate high-efficiency metasurfaces with low cost. To demonstrate the efficiency of the proposed fabricati

Eleven patients with juxtafusional degeneration syndrome underwent artificial disc replacement (ADR). Of these, five patients followed up for >6 months were analyzed for the current report. Surgery for juxtafusional degeneration was performed mean 4.9 years from their initial operation. The presenting features were neurologic compromise in four and severe back pain in one, with a mean Oswestry Disability Index (ODI) score of 64%. The replaced levels were L1-L2 in one, L3-L4 in three, L4-L5 in on

Therapeutic study, Level IV (case series, [patients treated one way with no comparison group of patients treated in another way]). See the Guidelines for Authors for a complete description of the levels of evidence.

Quantitative texture analysis, which included calculation of the orientation distribution function, was used to demonstrate textures in hot‐pressed and subsequently annealed silicon carbide (SiC). The results indicated that the hot pressing and annealing could produce strong textures in SiC. Grain rotation during hot pressing and preferred grain growth of plate‐shaped α‐SiC grains during annealing both apparently contributed to texture development in the SiC materials. The {111} pole figure in h

BACKGROUND: In the midthoracic region, a fluroscope guided epidural block has been proposed by using a pedicle as a landmark to show the height of the interlaminar space (Nagaro's method). However, clinical implication of this method was not fully evaluated. We studied the clinical usefulness of a fluoroscope guided thoracic epidural block in the midthoracic region. METHODS: Twenty four patients were scheduled to receive an epidural block at the T6-7 intervertebral space. The patients were place

OBJECTIVE: To compare the efficacy of ramosetron, midazolam, and the combination of ramosetron and midazolam in the prevention of postoperative nausea and vomiting (PONV) in female patients undergoing thyroidectomy. METHODS: Patients were randomized to receive 0.3 mg ramosetron (Group R), 75 µg/kg midazolam (Group M) or 0.3 mg ramosetron combined with 75 µg/kg midazolam (Group RM) before the induction of anaesthesia. PONV, use of rescue antiemetics, pain severity and fentanyl consumption were as

BACKGROUND: Pulsed radiofrequency (PRF) is a treatment modality that alleviates radicular pain by intermittently applying high-frequency currents adjacent to the dorsal root ganglion. There has been no comparative study on analgesic effect according to the position of the needle tip in PRF treatment. The objective of this study is to evaluate the clinical outcomes of PRF according to the needle tip position. METHODS: Patients were classified into 2 groups (group IP [group inside of pedicle] and

Background and Objectives: Local infiltration analgesia (LIA) represents a potential approach to reducing pain in patients undergoing total hip arthroplasty (THA). The pericapsular nerve group (PENG) block also provides adequate analgesia for fractures and THA. As most hip surgeries use a lateral incision, affecting the cutaneous supply by branches of the lateral femoral cutaneous nerve (LFCN), the LFCN block can contribute to postoperative analgesia. However, no studies have investigated the ef

Complex regional pain syndrome (CRPS) is a condition associated with neuropathic pain that causes significant impairment of daily activities and functioning. Nuclear factor kappa B (NFκB) is thought to play an important role in the mechanism of CRPS. Recently, exosomes loaded with super-repressor inhibitory kappa B (Exo-srIκB, IκB; inhibitor of NFκB) have been shown to have potential anti-inflammatory effects in various inflammatory disease models. We investigated the therapeutic effect of Exo-s

The aim of this study was to assess the antinociceptive activity of ginseng total saponins (GTS) on hyperalgesia induced by repeated intramuscular injections of acidic saline in rats and to examine the mechanisms involved. Rats were injected intraperitoneally with a 0.9% saline vehicle or various doses of GTS after the development of hyperalgesia. Rats were then injected with N-methyl-D-aspartate (NMDA) or naloxone 10 min before GTS injection. The mechanical withdrawal threshold (MWT) was assess
