This is a case report of a 38-year-old man with severe radiating pain on upper extremity after cervical total disc replacement (TDR). We faced an unusual complication that has not been reported yet. He underwent cervical TDR for left central disc protrusion on C5-6. After the surgery, preoperative symptom disappeared. However, at postoperative 1 year, he complained severe right-sided radiating ...

The clinical case is described of a 46-year-old patient, attended at the Traumatology office Centro de Diagnóstico Integral Chuao, Baruta municipality, Miranda state, Venezuela, who suffered right leg injury as result an accident mechanic workshop where he worked. He went for consultation week after with compartment syndrome anteroexternal region leg. A wound stitches in affected area attracted...

UNLABELLED The technique of percutaneous endoscopic lumbar discetomy (PELD) in the transforaminal approach has evolved over the years due to the advances in endoscopic photology and instrumentation and become the most popular technique for lumbar disc herniation. Although PELD offers many advantages, the indications of PELD are limited mostly to non-migrated or low-migrated disc herniation. It ...

Intradural disc herniation is a serious and rare complication of intervertebral disc rupture. The preoperative diagnosis of intradural disc herniation is still difficult despite new neuroradiologic investigation possibilities including computerized tomography and magnetic resonance imaging and it is usually diagnosed by during surgery. Here we present an intradural disc herniation case at the l...

It is expected that an average protostar will undergo at least one impulsive interaction with a neighbouring protostar whilst a large fraction of its mass is still in a massive, extended disc. Such interactions must have a significant impact upon the evolution of the protostars and their discs. We have carried out a series of simulations of coplanar encounters between two stars, each possessing...

A hendekakaihekaton peptide fragment has been prepared by cyanogen bromide cleavage of the NH2-terminal 134-residue fragment of human pituitary growth hormone. It was characterized by amino-acid and end-group analyses, exclusion chromatography, disc electrophoresis, circular dichroism, and ultracentrifugation. The fragment, corresponding to amino-acid residues 15-125 in the hormone molecule, po...

Percutaneous disc surgery, also known as percutaneous discectomy (PD), for herniated nucleus pulposus (HNP) was introduced by Hijikata [1] in Japan. Indeed, as compared with traditional disc surgery such as love’s procedure, PD is minimally invasive since it can be performed under local anesthesia. However, Hijikata’s technique does not use a spinal endoscope; thus, its reliability for the remo...

STUDY DESIGN Assessment of the reliability of standardized magnetic resonance imaging (MRI) interpretations and measurements. OBJECTIVE To determine the intra- and inter-reader reliability of MRI parameters relevant to patients with intervertebral disc herniation (IDH), including disc morphology classification, degree of thecal sac compromise, grading of nerve root impingement, and measuremen...
