Release and reattachment of the coracoacromial ligament: a cadaveric study.

The purpose of this study was to examine the anatomy and ability to reattach the coracoacromial ligament (CAL) after acromioplasty. Twenty-eight fresh cadaveric shoulder specimens were dissected, and the CAL dimensions and pattern of attachment were examined. The ability to reattach the CAL to the anterior acromion after acromioplasty was investigated, comparing release along the anterior acromion (traditional anterior acromioplasty) versus subperiosteal elevation from the acromial undersurface. The influence of CAL length, acromial "type," and amount of acromioplasty on reattachment were examined. In 96% of the specimens (27 of 28) confluent medial and lateral bands of the CAL insertion along the acromion precluded "selective" release. The ability to anatomically reattach the CAL was directly related to the method of ligament release (anterior release versus subperiosteal elevation) (p < 0.0001). When directly released from along the anterior acromion, the CAL could not be anatomically reattached in any specimen. Nonanatomic reattachment to a more medial anterior acromial insertion site, however, was possible in 22 (79%) of 28 specimens. Reattachment required an average medial positioning of 60% (range 16% to 88%) along the anterior acromion from the anterolateral tip. Six (21%) specimens could not be reattached despite attempted medial positioning. In contrast, when subperiosteally elevated from the anterior inferior acromion, the CAL was reattachable in all specimens, anatomically in 26 (93%) of 28. The two nonanatomic reattachments required medially reattaching the ligament's normal acromial insertion by an average of 30%. There was no relationship between specimen sex, age, presence of rotator cuff tear, type of acromion, and CAL reattachment. The confluent anatomy of the CAL does not permit "selective" release of discretely identifiable portions of the CAL (i.e., the lateral band). In cases in which CAL restoration is important, careful subperiosteal elevation from the acromial undersurface will facilitate anatomic reattachment. Standard release of the CAL from the anterior acromion precludes anatomic, and in some cases any, reattachment of the CAL.

Guidelines for improving resident dining experiences in long-term care facilities.

This article is a part of a larger study that identified nutrition education needs for nurses and nursing assistants that resulted in an educational intervention. The purpose of this article is to introduce newly developed evidence-based dining room guidelines. These guidelines can be used as a part of nursing homes' quality improvement programs to evaluate dining services and assist facility staff to identify problem areas.

Nurse-aid management of fractures: 3.

The healing process following a fracture is complex and dependent on various factors for success. This article, the last in a 3-part series, examines the different stages of healing and discusses the complications that may arise.

Nurse-aid management of fractures: 1.

Fractures occur in the bones of any age group, even the newborn, and are caused in any number of different ways. This article is the first in a three-part series that will examine the causes and types of fractures, the symptoms and presenting factors, nurse-aid intervention and the healing process.

Nurse-aid management of fractures: 2.

The principles of the management of fractures are fairly straightforward and yet there are many practical points to consider. This article, the second in a three-part series, considers the basic steps in treatment and the necessary nurse-aid intervention for fractures at specific sites.

Leak rate of latex gloves after tearing adhesive tape.

Anesthesiologists use latex gloves to provide barrier protection against infectious disease or contamination while providing anesthetic services. The performance of these services often involves tearing tape. The purpose of this study was to test the effect of tearing adhesive tape on permeability of latex examination gloves and to test the effect of an adhesive-sparing moisturizing cream on permeability of latex gloves used to tear adhesive tape. In a blinded, randomized, controlled laboratory experiment, 48 nonsterile latex examination gloves (24 pairs) were randomized to 1 of 2 groups. Adhesive-sparing moisturizing cream, 0.1 mL, was applied to 12 glove pairs; the remaining 12 pairs served as controls. Each of the 24 pairs of gloves were used to tear five 4-cm strips of cloth adhesive tape from a standard 1 1/2-inch roll. After initial inspection for obvious tears, each glove was tested for leaks using the watertight test as specified by the American Society for Testing and Materials (ASTM). Data recorded included the identity of the investigator tearing tape, number of holes initially observed, number of holes observed from the ASTM test, location of holes, glove classification as right or left hand, and treatment group. Based on the study, the authors concluded that health care providers who tear adhesive tape while wearing latex gloves should be aware that there is a high probability that the gloves no longer form a protective barrier and that adhesive-sparing moisturizing cream applied before tape is torn increases barrier protection.

Grand rounds for SNs and RNs.

The use of Nursing Grand Rounds as a teaching tool helps students gain clinical competence and become more proficient in nursing processes. Adaptation of this learning tool for staff development could be an important strategy for personal and professional growth of nurses in gerontological settings.
