Recent advances in technology and the refinement of neurophysiological methodologies are significantly changing intraoperative neurophysiological monitoring (IOM) of the spinal cord. This review will summarize the latest achievements in the monitoring of the spinal cord during spine and spinal cord surgeries. This overview is based on an extensive review of the literature and the authors' personal experience.

Background And Purpose: Embolization of a spinal cord arteriovenous malformation (SCAVM) is still considered risky. We evaluated the efficacy and reliability of pharmacologic provocative testing with neurophysiologic monitoring in the embolization of SCAVMs.
Methods: We retrospectively analyzed results of 60 provocative tests during 84 angiographic procedures (in 52 patients) with intended endovascular embolization.

Objective: To determine the absolute and relative refractory period (RRP) of fast conducting axons of the corticospinal tract in response to paired high intensity (HI or supramaximal) and moderate intensity (MI or submaximal) electrical stimuli. The importance of the refractory period of fast conducting corticospinal tract axons has to be considered if repetitive transcranial electrical stimulation (TES) is to be effective for eliciting motor evoked potentials (MEPs) intraoperatively.
Methods: Direct (D) waves were recorded from the epidural space of the spinal cord in 14 patients, undergoing surgical correction of spinal deformities.

To do a successful total knee arthroplasty (TKA), adequate exposure of the tibial plateau and distal femur is required. Difficulty with exposure often is encountered in the patient with a stiff or ankylosed knee. This can lead to complications including component malpositioning and extensor mechanism problems, such as patellar tendon rupture.

Newer prosthetic total knee arthroplasty (TKA) designs as well as unicondylar TKAs spare the anterior cruciate ligament (ACL). Although success of these procedures requires near normal ACL function, little has been written about the histologic features or the arthritic ACL. This study was designed to histologically evaluate the ACL for microscopic evidence of degeneration.

The literature on routine patellar resurfacing documents that the rate of anterior knee pain after TKA is the same whether the patella is resurfaced or unresurfaced. The complication rate is different in these groups. In patients in whom the native patella is left, the rate of reoperation is approximately 10%.

Our case report describes the electrophysiological features associated with the development of a spinal epidural hematoma during surgery of the lumbar spine. It stresses the importance of the evaluation of nonsurgical factors, which can potentially affect intraoperative evoked potentials; in this case, epidural local anesthetic or epidural hematoma.

Technical complications during embolization of craniospinal lesions using NBCA may be classified as nonspecific catheterization-related or specific embolization-related. Catheterization- related complications include vessel injuries such as spasm, dissection or perforation, catheter injuries and thrombus formation. Embolization- related complications include occlusion of normal territories, migration of the embolic material to the venous side, and catheter gluing to the vessel wall.

Arthroscopic debridement represents one option for treatment of the patient with degenerative arthritis of the knee. Numerous procedures, including joint lavage, removal of loose bodies, partial meniscectomy, and techniques to stimulate cartilage repair may be included under this topic. Understanding surgical indications and clinical results requires differentiation of these individual components where possible.

During primary and revision TKA, difficulties with exposure may be due to poor motion, obesity, and patellar baja. To gain accurate component positioning and avoid catastrophic complications with the extensor mechanism, a stepwise approach to optimizing the exposure should be used. In cases where the standard medial parapatellar arthrotomy is inadequate, a quadriceps snip is helpful.

Posterior cruciate ligament-substituting total knee prostheses have been used extensively since the original posterior-stabilized condylar prosthesis was introduced more than 2 decades ago. The key design principle of this prosthesis was the incorporation of a cam and post mechanism on the femoral and tibial components. This mechanism was intended to function as a mechanical substitute for the posterior cruciate ligament, to optimize prosthesis roll back in flexion, and to avoid flexion instability by preventing posterior subluxation.

Direct (D) corticospinal tract discharges were recorded epidurally in patients at anesthetic depths suppressing indirect (I) activity and were elicited by two equal transcranial electrical stimuli. The recovery of amplitude of the second D wave (D2) was a function of the interstimulus interval (ISI) and the stimulus duration. For example, with a 100 micros pulse, there was no response at an ISI of 1.

The purpose of this study is to evaluate efficacy and reliability of chemical provocative testing using neurophysiological monitoring prior to embolization of spinal cord AVMs (SCAVMs). We performed retrospective analysis of provocative testing using sodium amytal and lidocaine injected superselectively in 41 angiography and/or embolization procedures in 26 patients with a SCAVM, including 23 amytal and 26 lidocaine injections.All procedures were performed under general anesthesia using neuroleptic drugs, and with monitoring of cortical somatosensory evoked potentials (SEPs) and trans-cranial motor evoked potentials (MEPs).

The success of total knee arthroplasty can be jeopardized by poor wound healing. In the current study, the results of knee arthroplasty after soft tissue expansion were reviewed retrospectively in 27 patients (29 knees) at risk for problematic healing. The incidence of wound complications was recorded for all patients after the expansion procedure and the arthroplasty.
