ABSTRACT
A common assumption among orthopedic surgeons is that cemented/hybrid total hip arthroplasty (THA) results in lower transfusion requirements than noncemented THA. The hypothesized mechanism to account for transfusion differences is that cement application, after polymerization, decreases perioperative blood loss. To evaluate this theory, a retrospective matchedpair study was performed to quantify perioperative, intraoperative, postoperative blood loss, and transfusion requirements among patients undergoing cemented/hybrid and noncemented THA. Twenty-five THA procedures were either cemented or hybrid and 25 were noncemented. Patients were matched with respect to age, gender, weight, and diagnosis.
Six patients in the noncemented group and 1 0 in the cemented/hybrid group received autologous blood in the Post Anesthesia Care Unit. Among this subgroup, those in the cemented/hybrid group received a significantly greater volume of transfused blood (519.20 ml, versus 291 .67 mL in the noncemented group, P<.017).
After stratifying patients by gender, additional analysis revealed a greater total blood loss in the male population than in females (1848 mL versus 1464 mL, P < .004). Males also had a greater drain volume (548 mL versus 414 mL, P < .02). The female population utilizing hormone replacement therapy (HRT) was found to have a lesser blood loss (810 mL versus 1209 mL, P < .0107) and received a smaller amount of transfused blood (1 1 64 mL versus 1 377 mL) than those who were not on HRT. Other significant findings included a shorter length of stay in the cemented/hybrid group (6.85 versus 7.56 days, P< .012).
Based on this matched-pair retrospective analysis of blood requirements, there is no indication that cemented/hybrid and noncemented THA procedures result in different blood requirements. However, differences were found in several areas when the population was stratified by gender. The information obtained from this study is important in its ability to solidify a foundation from which blood management decisions can be made.
Treatment of Symptomatic Glenoid Loosening Following Unconstrained Shoulder Arthroplasty
Authors: Hawkins Richard J , Greis Patrick E , Bonutti Peter M 
Published: April 2021

ABSTRACT
Nine patients with symptomatic glenoid loosening were identified and ultimately underwent surgical revision. Preoperative assessment demonstrated that pain, decreased range of motion, and functional disability were common features. A painful clunking sensation with forward elevation of the arm was noted in four of the nine patients. At surgical revision, a grossly loose glenoid component was found in all cases and removed. Seven of the nine patients underwent revision using another cemented glenoid component, and two patients were left with a hemiarthroplasty due to glenoid bone deficiency. Results following revision surgery demonstrated increased range of motion, decreased pain, and increased functional ability with good overall patient satisfaction in seven of nine patients. Two patients in whom revision glenoid components were implanted were considered failures due to recurrent loosening. Although revision of the glenoid component is often technically feasible, recurrent loosening may occur. Revision to a hemiarthroplasty may be an acceptable alternative to glenoid replacement.

ABSTRACT
High tibial valgus osteotomy for varus gonarthrosis was performed in 63 consecutive patients in a homogenous agricultural population using two different surgical techniques. Patients were divided into two groups. A two-level Mittelmeier osteotomy was performed in group A patients, and a lateral closed wedge high tibial osteotomy using the AO/ASIF L-plate was performed in group B patients. Operations were performed by two different groups of surgeons. Patients were evaluated postoperatively for correction of knee axis, functional result, subjective impression, and complications.
In group A patients, 80% of the operated knees were corrected to the mechanical axis and in group B patients, 82% of the knees were corrected to 6°-10° valgus of the anatomical axis. Ninety percent, 70%, and 54% of group A and 91%, 73%, and 57% of group B patients were rated as satisfactory results at 5, 9, and 12 years postoperatively, respectively; these differences were not statistically significant. One year postoperatively, 91% of group A and 96% of group B patients reported their symptoms had improved. However, patient satisfaction decreased at 5, 7, and 12 years postoperatively, with 91%, 89%, and 66% of group A and 96%, 93%, and 68%, respectively, of group B patients reporting their symptoms had improved; these differences were not statistically significant. Postoperatively, most patients returned to full agricultural activity. Total knee arthroplasty, which was later required in 12% of the knees, was not significantly jeopardized by the previous osteotomy.

Authors: Gonzalez Mark H , Bylak Joseph 
Published: April 2021

ABSTRACT
Thirty-five hands in 30 consecutive patients with carpal tunnel syndrome confirmed by nerve conduction velocity, 2-point discrimination <6 mm, and no thenar weakness were injected with corticosteroid. Patients underwent follow-up at 3, 6, 1 2, and 1 8 months or until symptoms recurred. Symptomatic relief obtained at 3 months was 34% and only 11% at 12 and 18 months. No correlation with clinical response and age, duration of symptoms, or sex was noted.
Value of Measuring Bone Density Serial Changes on a Picture Archiving and Communication Systems (PACS) Monitor in Distraction Osteogenesis
Authors: Shim Jong Sup , Chung Kwang Hoon , Ahn Joong Mo 
Published: April 2021

Abstract
Serial changes of bone density in 26 femora and 22 tibiae that underwent leg lengthening by distraction osteogenesis were investigated by measuring the pixel value shown on a picture archiving and communication systems (PACS) monitor. The pixel value of the original cortex did not change significantly until the external fixator was removed. The pixel value of the distraction sites did not change significantly for the first 5-6 weeks/cm, but rapidly increased after 7 weeks/cm in the femur and tibia, then slowly increased after 8 weeks/cm. The serial changes of the pixel value of the distracted bone showed a sigmoid curve, rather than a straight increasing line. The relative pixel values of the lengthening sites were >95% in three of the four cortices at external fixator removal. Thus, the pixel value of PACS is a rapid and easy method for the detection of bone density changes in distraction osteogenesis.
Quantification of Guided Regeneration of Weight-Bearing Bones
Authors: Mosheiff Rami , Friedman Adi , Friedman Michael , Liebergall Meir 
Published: April 2021

Abstract
An accurate histological evaluation system was established to improve and quantify the compatibility of membranes to provide bone regeneration in a large mid-diaphyseal bone defect, complementing radiographic evaluation. New bone formation obtained in critical segmental defects covered with tubular ethyl cellulose membranes was examined. Computerized radiography showed gradual new bone formation, which slows after 6 weeks. In a parallel histomorphological assessment, a characteristic process of new bone formation occurs inside the confined space and surrounding tissues. Histological findings are summarized according to the new scoring system, which clarifies the mechanism and provides complementary quantification of guided bone regeneration.
Femoral Version: Definition, Diagnosis, and Intraoperative Correction With Modular Femoral Components
Authors: Kudrna James C 
Published: April 2021

abstract
Normal femoral version contributes to the inherent stability of the hip joint. Abnormal version is found in a variety of hip diseases afflicting children and adults. At the time of reconstruction for end-stage hip disease, maintaining proper femoral version in conjunction with acetabular version allows for hip stability and unimpeded functional range of motion. In those instances where femoral version is significantly abnormal, a means of correction at time of surgery is necessary. Non-modular femoral components allow for minor adjustments in version at time of surgery. To accommodate significant versional abnormalities, the modular S-ROM (DePuy Orthopaedics Ine, Warsaw, lnd) was introduced in 1984. In a series of 156 primary S-ROM total hip arthroplasties, the ability to correct for abnormal version resulted in excellent clinical results with no incidence of hip instability and excellent range of motion.
Modular Cementless Total Hip Arthroplasty for Hip Infection Sequelae
Authors: Lim Seung-Jae , Park Youn-Soo 
Published: April 2021

abstract
Childhood hip infection may produce significant anatomical deformations leading to the premature onset of secondary osteoarthritis. Total hip arthroplasty (THA) in these patient populations can be technically challenging and has been associated with high complication rates. This article reports the results of 58 cementless THAs with use of a modern implant design. The complication rate, including one recurrent infection, was relatively low. Cementless THA with use of a modular stem coupled with a metal-backed socket was found to be an effective and reliable treatment option for patients with the late sequelae of infective hip arthritis.
Minimally Invasive Navigated Knee Surgery: An American Perspective
Authors: Stulberg S David 
Published: April 2021

abstractMinimally invasive total knee replacement surgery may make it possible for patients to undergo the procedure with less pain and recover from the surgery more quickly than has been previously possible. However, minimally invasive techniques have the potential for being associated with a number of complications, including implant and limb malalignment. Computer-assisted technologies used in conjunction with minimally invasive techniques allow the accuracy with which the procedures are performed to be retained.

Authors: Saragaglia Dominique , Roberts Jason 
Published: April 2021

abstract
The authors used computer navigation to perform osteotomies around the knee. The purpose of this article is to present the authors' surgical technique and to discuss double-level osteotomy of the femur and tibia to avoid altered joint line obliquity in genu varum deformity. The authors conducted two studies. The first study was a cohort study comparing navigated high tibial osteotomies and conventional high tibial osteotomies. The results showed a 96% reproducibility in achieving a mechanical axis of 184°±2° in the navigated group compared to a 71% reproducibility in achieving a mechanical axis of 184°±2° in the conventional osteotomy group (P<.0015). The second study was a prospective study on double-level osteotomy and showed that the preoperative goal of 182°±2° has been achieved in 91 % of patients.
A Learner Analysis Experiment: Cognitive Style Versus Learning Style in Undergraduate Nursing Education
Authors: Cranston Charles M , McCort Barclay 
Published: April 2021

ABSTRACT
The purpose of this study was to determine whether or not statistically significant differences existed among performance levels of beginning undergraduate nursing students when compared according to cognitive style and learning style subgroups. The sample consisted of 60 nursing students enrolled in an introductory clinical nursing course at a regional community college in the Southwest. Subjects were randomly assigned to experimental and control groups and were administered separate learner analysis instruments. The 30 students in the control group were given a cognitive style mapping assessment, while the 30 students in the experimental group were given a learning style assessment. The control group and experimental group were both given group interpretations of the learner analysis data. As with all nursing students at the College, the control group was allowed individual learning prescriptions by the instructor. The experimental group was allowed no further data interpretation. Both groups were to use the learner analysis data to assist them in completing the course.
Performance data were collected during the ensuing semester from five evaluations covering specified modules: "Basis Human Needs;" "Professional Ethics and Communications;" "Emergency Care, Fluids, and Electrolytes;" "Death and Oncology;" and "Pharmacology." Analysis of the data with t-tests revealed no significant differences (p=.05) in performance among the experimental or control groups. Mean scores from the evaluation data did indicate a slightly higher performance level from the control group in four of the five modules.
Selected Pre-Admission and Academic Correlates of Success on State Board Examinations
Authors: Yocom Carolyn J , Scherubel Janet C 
Published: April 2021

ABSTRACT
The purpose of this retrospective study was to examine student performance prior to and following admission to a baccalaureate nursing program in comparison with their performance on the individual sections of the State Board Test Pool Examinations (SBE) and an overall assessment of Pass-Fail on the SBE. The following hypothesis guided the study: It is possible to determine which variables are most influential in predicting success on SBEs. Additional research questions addressed the relationship between theoretical and clinical nursing courses and SBE performance, the pertinence of various demographic variables, and differences between students passing and failing SBEs. The sample was composed of the 139 Class of 1980 graduates for whom SBE results were available. Data pertaining to individual course grades, grade point averages, credit hours earned prior to admission, school attended prior to admission, previous academic degree, race, and all SBE scores were obtained.
Stepwise multiple regression analysis revealed the junior or senior year cumulative clinical nursing theory GPA had the highest weighting in each section of the SBE and for Pass-Fail SBE. Cumulative clinical nursing theory GPAs were more highly correlated with SBE performance than were cumulative clinical nursing practicum GPAs. The pre-admission liberal arts and cumulative GPAs were also highly correlated with performance. In addition, the number of credit hours earned prior to admission, school attended, and race of the student were found to be significant factors. Significant differences between students passing and failing SBEs were found in regard to their level of performance in course work.
Re-Entry Women in Baccalaureate Nursing Programs: The Achievement of Selected Developmental Tasks
Authors: Bueche Maria N 
Published: April 2021

ABSTRACT
This study sought to determine if there is a difference in the level of development, as assessed by the Student Developmental Task Inventory (SDTI-2), between the traditional age woman and the re-entry woman who has entered a baccalaureate nursing program. It builds upon the theoretical formulations of accepted principles of human growth and development and recent life cycle research, which suggests that further achievement of developmental tasks is possible throughout adulthood.
The subjects consist of 156 traditional age and 50 reentry women nursing students. Data were analyzed with the use of the subprograms "Frequencies" and "T-Test" of the Statistical Package for the Social Sciences (SPSS). Examination of the null hypotheses related to the achievement of developmental tasks and subtasks revealed that the traditional age woman and the re-entry woman did not differ on the majority of the developmental tasks and subtasks.
Implications for nurse educators are discussed.
The Dean's Job Satisfaction: Its Relationship to Organizational Structure
Authors: Frank Betsy 
Published: April 2021

ABSTRACT
The purpose of this study was to explore the relationship between formal organizational structure and the dean's job satisfaction. A two-part questionnaire was sent to 345 deans of Baccalaureate and Higher Degree nursing programs. Seventy-three percent responded. The findings showed that decentralization and some degree of complexity and fonnalization were related to job satisfaction. In spite of these findings, deans should consider all personnel, academic, and budgetary implications before proceeding with organizational restructuring.
Community Health Learning Experiences and Political Activism: A Model for Baccalaureate Curriculum Revolution Content
Authors: Williams Armenia 
Published: April 2021

ABSTRACT
Nursing education is involved in a curriculum revolution that decries behaviorist theory. One model for the new educational approaches is political activism that involves faculty and students in experiences of caring client advocacy. Content, theory, and experiences in communityhealth nursing integrate community activism and sociopolitical concepts. Sample approaches that blend curriculum revolution and political activism concepts are included. Such approaches can easily be used as part of the lived experience of community-health nursing education.
Effect of a Program to Increase the Cognitive Level of Questions Asked in Clinical Postconferences
Authors: Wink Diane M 
Published: April 2021

ABSTRACT
This study examined the effect of a program to increase the percentage of cognitively high-level questions asked in clinical postconference. Fourteen faculty and the students in their clinical groups comprised the convenience sample. Pre- and postintervention data on the cognitive level of questions asked by the treatment (N = 10) and control (N = 4) groups were collected by way of audiotapes. Treatment group faculty participated in an intervention designed to improve their use of questions.
Prior to the intervention, there was no statistically significant difference in the cognitive level of questions asked by faculty or students in the treatment and control groups. Following the intervention, faculty in the treatment group asked a statistically significant higher percentage of cognitively high-level questions (p = 0.012 [one-tailed]), but there was no statistically significant difference between the students in the treatment and control groups.
The Clinical Decision-Making Processes of Student Nurses
Authors: Tschikota Sharon 
Published: April 2021

ABSTRACT
This descriptive study examined the clinical decisionmaking processes used by 19 female senior diploma nursing students in a simulated client situation. The subjects were divided into two groups, with either an internal or external locus of control, as measured by the Rotter InternalExternal Locus of Control Scale. From a content analysis of the data, six decision-making elements and eight decisionmaking processes were identified. The frequency and pattern of use of the decision-making processes differed between internally and externally oriented subjects. Internal subjects used a significantly higher proportion of complex decision-making processes than the external subjects (z - 3.48; p<.01). All subjects were found to use decision-making elements and processes in a manner that reflected novice characteristics and supported the theoretical framework of information-processing theory. These findings have implications for nurse educators in relation to teaching strategies that facilitate clinical decision-making ability and internalization strategies for students with an external locus of control.
Clinical Learning Experiences and Professional Nurse Caring: A Critical Phenomenological Study of Female Baccalaureate Nursing Students
Authors: Kosowski Margaret Mary Rubritz 
Published: April 2021

ABSTRACT
The purpose of this critical phenomenological study was to discover, describe, and analyze how nursing students learn professional nurse caring in the clinical context of nursing education. In this article, I report on interviews from 18 female baccalaureate nursing students, 17 of whom are European American and one of whom is African American. Participants in this study narrated their stories about learning caring by first describing their understanding of how they created caring with patients. After uncovering the layers of their patient care interactions, they were then able to answer the research question of how they learned caring in clinical. Because participants' interactions with patients were the context for the development of their understanding of caring, I identify the relational theme of caring and interacting with patients as the central focal point for narrating stories about caring. From the data analysis, I report two constitutive patterns: the first, creative caring, contains seven themes, and the second, learning caring, contains five themes. Findings from this research are summarized as "embodied caring knowledge." This research has implications for nursing faculty, students, and practitioners who are interested in enhancing their understanding of living and learning caring within nursing.
Why Do Women Choose Nursing?
Authors: Boughn Susan , Lentini Alison 
Published: April 2021

ABSTRACT
To answer the question, "Why do women choose nursing?", female nursing students were given an opportunity to speak "in their own voices" to reveal their needs, motivations, and expectations. In a study employing grounded theory methodology, 16 female nursing students were interviewed and audiotaped for initial constant comparison analysis. Further analyses employing coding, categorizing, comparing, and contrasting of data made it possible to isolate recurrent words and phrases, and to identify concepts for the purpose of theory building. Reliability was established by both stability analysis and reproducibility analysis. Validity was supported by construct (convergent and discriminant) and representational componente. Not surprisingly, the construct of desiring to care for others was readily apparent. However, it was power and empowerment that emerged from the interviews as the most resounding and fully developed construct of the study. Students' references to practical motivations for choosing nursing were so notably scarce that their virtual omission constituted an important theme.

Published: April 2021

ABSTRACT
Reflective thinking, closely related to critical thinking, is discussed as an essential teaching-learning procesa to help students in introductory professional courses develop personal professional philosophies. Reflective thinking opportunities used by nurse educators and teacher educators include students' own experiences, actual case studies, and media presentations. Using reflective thinking to develop personal professional philosophies helps students view themselves as future participants in their chosen professions.
