The radical neck dissection is an operation for the management of lymph node metastases from primary sites involving the oral cavity, larynx, and other areas of the head and neck. In this procedure, the spinal accessory nerve is removed along with other structures. In modified neck dissection the spinal accessory nerve is preserved. Patients undergoing the modified neck dissection have had variable functional outcomes from little or no pain or disability, to significant muscle dysfunction. Our group hypothesized that patients with good functional outcomes following modified neck dissection may have had motor contributions from C2, C3, or C4 branches, while those with less favorable outcomes did not. To demonstrate the presence of motor input and its significance both from the spinal accessory nerve and the branches of the cervical plexus, we utilized intraoperative electroneurography. We find that although there is motor contribution from C2, C3, and C4 to the trapezius muscle, it was not consistent or significant. © 1997 John Wiley & Sons, Inc. Muscle Nerve 20, 279–285, 1997.

Although the surgical anatomy of the spinal accessory nerve and the cervical plexus has been extensively described, the exact motor innervation of the trapezius has been controversial. Attempts to resolve this question have involved anatomic or electrophysiologic studies in human embryos and animals. Extrapolation of the results to adult humans may not be correct. Accurate identification of muscle innervation is obtainable by intra-operative measurement of motor action potentials produced by direct stimulation of the accessory nerve and the cervical plexus. The study involved 14 patients undergoing supraomohyoid or modified neck dissections. Under direct vision, stimulating electrodes were placed on the identified nerves and motor action potentials, and latencies were recorded by surface electrodes placed over the three portions of the trapezius. In 13 patients, when the accessory nerve was stimulated, motor action potentials were obtained in 13 of 13 in the first portion, 11 of 13 in the second portion, and 10 of 13 in the third portion of the trapezius. In the last patient, the accessory nerve ended in the sternocleidomastoid muscle, and innervation of the trapezius was via C3 as demonstrated by motor action potentials. Responses when the roots of the cervical plexus were stimulated varied. Three patterns were seen: In the first group (seven patients), motor action potentials were distinct from those recorded when the accessory nerve was stimulated. Additionally, latencies were different from those of the accessory nerve. The second group (four patients) had motor action potentials that were similar to those obtained from stimulation of the accessory nerve, although their corresponding latencies were different.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute knee pain is a frequently encountered problem in the clinical settings. In 2003, American Orthopedic Association recorded that 19.4 million people visited a physician because of a knee problem. Knee pain due to injuries is increasing even among the older population, as a greater number of persons are participating in recreational activities. The quadriceps tendon rupture is not a common condition among acute causes of knee pain. However, it can be quite debilitating. The usual clinical presentation includes a middle-aged person presenting with a history of fall accompanied by swelling and inability to extend the knee. Providers who are faced with this clinical situation should be able to recognize this condition sooner than later. It is very important that precise clinical decisions be made, so as to achieve best outcomes. This article reviews the etiology, epidemiology, clinical presentation, differential diagnosis, and management of quadriceps tendon rupture.

Purpose In order to prevent adverse events during the discharge process, coordinating appropriate community resources, medication reconciliation, and patient education needs to be implemented before the patient leaves the hospital. This coordination requires communication and effective teamwork amongst staff members. In order to address these concerns, the purpose of this paper is to incorporate the TeamSTEPPS principles to develop a discharge plan that would best meet the needs of the patients as they return to the community. Design/methodology/approach Through a gap analysis, barriers to discharge were identified from the following disciplines: nursing, social work, physical and occupational therapy, psychology, and rehabilitation physician. To improve communication, weekly meetings and twice-weekly huddles were implemented so that concerns regarding discharge obstacles could be identified and resolved. Visibility of discharge dates were improved by use of graduation certificates in patient rooms and green ribbons on patient wheelchairs. Findings After implementation of this discharge intervention, length of stay was reduced providing cost savings to the hospital, patient satisfaction on HCAHP surveys improved and demonstrated patient satisfaction with the discharge process, and readmission rates improved. Originality/value This study demonstrated that effective teamwork and communication can improve patient safety and satisfaction during the discharge period.
