RECENT ADVANCES IN THE USE OF LOW MOLECULAR WEIGHT HEPARINS AS PROPHYLAXIS FOR DEEP VEIN THROMBOSIS
Authors: Colwell Clifford W 
Published: April 2021

ABSTRACT
Low molecular weight heparins are providing a new prophylactic option for preventing deep vein thrombosis (DVT) in patients undergoing joint replacement surgery. Fragmentation of heparin in laboratory studies revealed differences in coagulation and bleeding factors. This unexpected finding led to clinical trials, starting in 1985 in Europe and the United States. By late 1993, more than 10 000 patients had been admitted to clinical trials of low molecular weight heparins (LMWH) for prevention of DVT. Results of these trials indicated that LMWHs were more effective than unfractionated heparins or warfarin in preventing DVT with no significant increase in bleeding noted.
IMPACTION GRAFTING: PRELIMINARY REPORT OF A NEW METHOD FOR EXCHANGE FEMORAL ARTHROPLASTY
Authors: Elting James J , Zicat Bernard A , Mikhail W E Michael , Hubbell John C , House Barbara S 
Published: April 2021

ABSTRACT
Gie et al described a method for femoral component revision using compressed morselized cancellous allograft and a cemented collarless polished taper stem. We have reviewed our first 37 exchanges performed in this manner. Results after 2 to 5 years have reflected few complications, a majority of satisfactory results, evidence of graft incorporation, and no mechanical loosening. Further study is necessary; however, these preliminary findings give rise to cautious optimism.
DIGITAL LENGTHENING USING THE CALLOTASIS TECHNIQUE
Authors: Seitz William H , Froimson Avrum I 
Published: April 2021

Abstract
A series of 14 lengthenings for congenital and posttraumatic digital deficiency has been carried out in a single stage utilizing individual, half-frame design, digital lengthening devices. These devices have afforded individual digital stability without need for additional external support and have provided between 2.0 cm and 3.5 cm lengthening per digit. In only one case was additional bone grafting necessary and in all cases the projected goal of lengthening was achieved. A slow rate of lengthening (0.25 mm in four daily increments) was associated with a minimal amount of pain, patients were able to utilize their hand for function during the lengthening period, and, in cases where physeal plates have remained open, continued growth has been experienced in the follow-up period.
THE USE OF A FOAM ANESTHESIA DONUT FOR THE POSITIONING OF A PATIENT IN THE BARBER CHAIR POSITION
Authors: Dvorkin Michael L , Bradley William 
Published: April 2021

ABSTRACT
The foam anesthesia donut proves quite useful in the positioning of the patient in the barber chair position. By placing the donut on top of the patient's face, it protects the patient's eyes from trauma by the assistants holding retractors. The endotracheal tube also can be secured to the ring, protecting it from disconnection during surgery. The inner foam of the donut, which is removed when applying to the face, also can be used to pad the ulnar nerve at the elbow.
FEMORAL LENGTHENING IN PATIENTS HAVING ABNORMAL IPSILATERAL HIP OR KNEE
Authors: Gabriel Keith R , Russell John M , Crawford Alvin H , Roy Dennis R 
Published: April 2021

ABSTRACT
Femoral lengthening using the Wagner technique was performed for 13 patients with abnormal adjacent joints. An average of 6.3 cm (19.5%) of lengthening was achieved. Three patients had no difficulties during lengthening. Transient non-surgical problems identified were blood pressure elevation, nerve palsy, and psychiatrie reactions. Significant obstructions or complications occurred 13 times in nine cases. These included contractures of ipsilateral joints, angulations of the lengthened femur, Wagner device slippage, nonunion, and late hip subluxation. Other authors have reported similar difficulties in patients with normal ipsilateral joints. In this series, the advantage of achieving greater length appeared to outweigh the complications.
TREATMENT OF ULNAR SHAFT FRACTURES: A PROSPECTIVE, RANDOMIZED STUDY
Authors: Atkin David M , Bohay Donald R , Slabaugh Peter , Smith Briant W 
Published: April 2021

ABSTRACT
The treatment of isolated ulnar shaft fractures is controversial. Previous studies comparing treatment options have been largely retrospective and nonrandomized. In this study, consecutive patients were randomized into treatment groups of long arm plaster immobilization, short arm plaster immobilization, or Ace Wrap bandage, based on the order of hospital admission. Thirty-one patients were followed until radiographic or clinical union, with no significant difference in time to union between groups. Age, sex, fracture pattern, and displacement did not significantly influence time to union or final angulation. Two patients in both the long arm cast group and the short arm cast group lost significant motion at final follow up. Seventy percent of patients in the Ace Wrap group failed treatment secondary to pain and were converted to plaster immobilization. Furthermore, patients in this group demonstrated significantly greater angulation than those treated in a long arm cast. Our results demonstrate that above-elbow plaster immobilization offers no advantage over below-elbow immobilization. We recommend short arm casting for a period of 8 weeks.
CLOSED REDUCTION AND PERCUTANEOUS STABILIZATION OF TIBIAL PLATEAU FRACTURES
Authors: Harper Marion C , Henstorf Jan E , Vessely Michael B , Maurizi Michael G , Allen William C 
Published: April 2021

ABSTRACT
Twenty-eight patients with tibial plateau fractures treated by closed reduction using forceful traction and percutaneous stabilization with pins or screws were reviewed. For six bicondylar fractures, transfixion pins with an external fixation device were used. In six cases, an arthroscopic exam was also done. For 21 patients, external support was used postoperatively. Twenty-one patients were followed an average of 26 months. All fractures healed. Functional ratings were: 14 excellent, 6 good, and 1 poor. Radiographic ratings were: 11 excellent, 9 good, and 1 fair. For fractures with large fragments without excessive comminution or severe central depression, this technique yields good results with minimal surgical morbidity.
EXPANDING THE USE OF THE ANKLE DISTRACTOR IN THE TREATMENT OF COMPLEX ANKLE FRACTURES
Authors: Rupp Robert E , Ebraheim Nabil A , Moronell Mark 
Published: April 2021

ABSTRACT
Use of the ankle distractor with ankle arthroscopy is well known to allow improved evaluation of the intraarticular surfaces. A less common application of the ankle distractor is for the treatment of complex ankle fractures. We evaluated the use of the ankle distractor in the treatment of six patients with ankle trauma. Five of these cases involved comminuted intraarticular fractures of the distal tibia, and one case involved a malunion of an ankle fracture with widening of the mortise. In each case, the ankle distractor increased the exposure of the ankle joint and allowed better access for fracture fragment reduction. There were no complications associated with the use of the distractor. The technique of using the ankle distractor in these situations is described.
A COMPUTER TOMOGRAPHIC CLASSIFICATION SYSTEM FOR THE DISPLACED INTRAARTICULAR FRACTURE OF THE OS CALCIS
Authors: Corbett Michael , Levy Andrew , Abramowitz Andrew J , Whitelaw George P 
Published: April 2021

ABSTRACT
The treatment of the displaced intraarticular fracture of the os calcis continues to be controversial. One of the reasons for this is the lack of a workable classification system which would allow comparison among different treatment modalities. Plain radiographs are unable to depict the complex three-dimensional pathology of this fracture. Computed tomography (CT) scanning, however, has the potential to quite accurately depict all components of this injury. At our hospital, a five-part, CT-based classification system has been utilized. This system suggests which fractures will do well with conservative care, and which fractures are amenable to operative stabilization.
The Ability of Various Acetabular Components to Resist Protrusio Migration
Authors: Benjamin James , Thomas Maxwell , Szivek John 
Published: April 2021

ABSTRACT
A foam model of a protrusio acetabulum with cylindrical voids of varying diameters was used to test acetabular components for their ability to resist migration within the defect. A bipolar component, a hemispherical cup, and a hemispherical cup with peripheral rim augmentation were tested in defects with diameters ranging from 1 to 3 mm less than the major diameter of the component. The cup with peripheral rim augmentation demonstrated 20% to 40% greater resistance to migration than the hemispherical cup, depending on the extent of under-reaming, with the bipolar component consistently demonstrating the lowest load to failure. The results of this study confirm the less-than-satisfactory clinical results seen with bipolar reconstruction of protrusio acetabuli, and support the use of "fixed" cups in these settings.
The Use of Three-Dimensional Computed Tomography in Evaluating Snapping Scapula Syndrome

Published: April 2021

ABSTRACT
This article evaluates imaging of the scapula and scapulothoracic joint in patients with snapping scapula, syndrome. Between 1990 and 1996, a total of 20 patients (1 0 men and 1 0 women) with snapping scapula syndrome were evaluated. Diagnosis was based on patient complaints and physical examination findings. There were 26 affected scapulae (6 patients had bilateral presentation). Imaging of the scapula included plain radiography, computed tomography (CT), and 3-dimensional computed tomography (3-D CT) reconstruction.
Plain radiography revealed bony incongruity between the anterior aspect of the scapula and the chest wall in 7 scapulae, CT revealed such incongruity in 19 scapulae, and 3-D CT revealed incongruity in all 26 scapulae. Treatment was conservative, consisting of nonsteroidal anti-tnflammatory drugs, a physiotherapy program, and subscapular injection of a local anesthetic and steroids. In 5 patients who responded poorly to conservative treatment, the region responsible for the snapping was resected. Pain relief and resolution of the snapping were complete following surgery in 4 patients, while pain and crepitation persisted in the fifth. Three-dimensional CT is recommended as the main imaging modality in the evaluation of any patient with snapping scapula syndrome who is a candidate for surgical intervention.
Clinical, Radiographic, and Scintigraphic Comparison of the Mechanical Stability of Mueller and Zweymueller Total Hip Prostheses

Published: April 2021

ABSTRACT
Twenty-two cemented Mueller and 25 uncemented Zweymueller total hip arthroplasties (THAs) were performed in the same period in 47 consecutive randomly selected patients with unilateral primary osteoarthritis. Patients were evaluated using the same clinical and radiographic protocol preoperatively; 3, 6, and 1 2 months postoperatively; and annually thereafter as well as with Tc 99m MDP three-phase bone scintigraphy 3, 6, 12, and 24 months postoperatively. At "? periprostatic regions of interest (ROIs) around the stem and socket of each prosthesis, several radiographic parameters and bone scintigram uptake grade were recorded and correlated to determine the significance of early scintigraphic uptake for prediction of the stability of cemented and uncemented THA components over time.
Around stable Zweymueller and Mueiler sockets, the radionuclide uptake was s'imHar during aì periods of observation. Radionuclide uptake around stable Zweymueller stems was significantly more than around stable Mueller stems at the medial femoral cortex 3 and 6 months postoperatively, at the lateral femoral cortex 3-24 months postoperatively, and near the tip of the stem 3 months postoperatively. Radionuclide uptake around stable Mueller stems was significantly more than around Zweymueller stems at the greater trochanter 6 and 1 2 months postoperatively and at the lesser trochanter 1 2 months postoperatively. Any significant deviation of radionuclide uptake at any ROI, time, and THA component during the first 2 years postoperatively in combination with radiographic findings of loosening should be considered a serious predictive sign for loosening of a Mueller or Zweymueller THA component.

Abstract
The Rocky Mountain Musculoskeletal Research Laboratory uses in vivo video fluoroscopy to evaluate kinematics of total knee arthroplasty. This method allows us to evaluate In vivo weight bearing activity for a variety of knee designs, as well as kinematics of the normal knee. Our proprietary method of automated model fitting allows for three-dimensional analysis obtained from twodimensional fluoroscopic images with minimal error. This article outlines the details of our kinematic analysis of the Low Contact Stress (LCS) Total Knee System (DePuy Orthopaedics Ine, Warsaw, lnd) rotating platform total knee and compares this design with fixedbearing posterior cruciate-retaining and posterior cruciate-substituting total knee and normal knee kinematics.
The Clinical History of Mobile-Bearing Patella Components in Total Knee Arthroplasty
Authors: Jordan Louis R , Dowd James E , Olivo Jane L , Voorhorst Paul E 
Published: April 2021

Abstract
Two hundred fifty-six primary cementless meniscalbearing total knee arthroplasties were performed between May 1985 and January 1989. All knees were replaced with a low contact stress metal-backed anatomic mobile patella. The average patient followup was 1 1 .5 years. No patellae were revised for failure of fixation and no dislocations or subluxations were reported. One patella was revised for polyethylene wear, and one well-functioning component was removed at the time of revision to facilitate range of motion and wound closure. The survival estimate at 12 years was 99.5%. Compared to the high incidence of failure of metal-backed fixed-bearing patellae components, the anatomic rotating patella provides durable long-term results with a low incidence of complications.
Latissimus Dorsi Pedicled Flap for Upper Extremity Soft-Tissue Reconstruction
Authors: Rogachefsky Richard A , Aly Ali , Brearley Wayne 
Published: April 2021

Abstract
The latissimus dorsi often is used as a functional muscle transfer to restore elbow and shoulder motion. Although less common, its use as a pedicled muscle flap with a split-thickness skin graft provides excellent soft-tissue coverage of large upper extremity wounds. Seven male patients ranging in age from 6-71 years were treated with a pedicled latissimus dorsi muscle flap and splitthickness skin graft for coverage of open wounds of the shoulder, arm, or elbow with exposed vital structures (mean wound size: 15x10 cm). The flap also was used as a functional muscle transfer in one patient to replace destroyed anterior and middle portions of the deltoid. Wounds resulted from trauma in three patients, infection following trauma in two, and sarcoma excision in two. All flaps healed well, and donor site morbidity was minimal. At mean 16-month follow-up (range: 3-41 months), all muscle flaps had contoured well, producing satisfactory cosmesis. Functional results were good, and all patients were satisfied with their outcome. The tendinous insertion is left intact to guard against excessive traction on the pedicle when the flap is used for soft-tissue coverage only.

Published: April 2021

Abstract
Eight patients with localized pigmented villonodular synovitis (LPVNS) of the knee were treated with arthroscopic and open techniques, with diagnosis confirmed by histological examination. Average patient age was 29 years (range: 13-50 years). At arthroscopy, all lesions except one were in the anterior compartment of the involved knee. Treatment consisted of complete local excision with partial synovectomy. This procedure was completed arthroscopically in seven patients. No recurrence was reported at average 24-month follow-up (range: 12-33 months). Arthroscopy is a valuable tool in the diagnosis and treatment of LPVNS.
The Educational Impact of a Course About Addiction
Authors: Jack Lynette W 
Published: April 2021

ABSTRACT
The purpose of this study was to evaluate the impact of a nursing course about addiction on baccalaureate nursing students' attitudes toward addictive substances and on their personal lifestyle behaviors. The course was a threecredit, 15-week offering, focusing on: 1) learning to care for addictive clients, and 2) learning to value responsible attitudes and healthy lifestyle behaviors, as a strategy for primary prevention of addiction in the nursing profession.
A non-random treatment group of 46 students enrolled in the course was compared with a control group of 36 students. Data were collected at the beginning and end of the term using Goodstadt's Drug Attitudes Scale and the Healthstyle Self-Test, and analyzed using a two-way analysis of variance with repeated measures over time. The treatment group made significantly greater changes than did the control group when measured by the tobacco subscale and the opiates subscale. Both groups showed a significantly decreased ability to manage stress at the end of the term. In addition, a subgroup of students who indicated a family background of drug or alcohol abuse reported significantly different lifestyle behaviors when compared with a subgroup of students whose families did not use drugs or alcohol.
Success in NCLEX-RN: Identifying Predictors and Optimal Timing for Intervention

Published: April 2021

ABSTRACT
This ex post facto study was designed to identify predictors of success in the NCLEX-RN and determine the optimal point in time for identifying students at risk. The convenience sample consisted of 407 graduates of an integrated, upper division, baccalaureate nursing program, 1984-1987. Prematriculation (total lower division GPA, science GPA, type of lower division College, age, and sex), junior year (three Nursing theory course grades) and pre graduation variables (three senior year nursing theory course grades and Mosby ASSESSTEST) were analyzed for predictive value. Nursing theory courses at the junior and senior year and the Mosby ASSESSTEST strongly correlated (p<.0001) with NCLEX performance. Discriminant analysis enabled successful classification of 62% of the sample at prematriculation, 81% at the end of the junior year, and 86% at the end of the senior year. The study indicates that students at high risk can be identified at the end of the junior year so that enrichment and support programs can be introduced at that time.

The Master's Prepared Mental Health Nurse: An Assessment of Employer Expectations
Authors: Brophy Elizabeth B , Rankin Donna , Butler Shirley , Egenes Karen 
Published: April 2021

ABSTRACT
A needs assessment survey seemed essential to a group of faculty members engaged in updating the curriculum in a Master's program in Mental Health Nursing in a University School of Nursing in the Midwest. An attempt was made to identify those nurse administrators who interviewed and hired clinical nursing personnel in hospitals in which psychiatric services were provided. Data were obtained from 23 respondents. The findings indicated that 1) Master's-prepared mental health-psychiatric nurses are being hired in the area; 2) at least 50% of the time, MSN graduates are expected to function in middle-management or administrative roles; and 3) Comprehensive Mental Health Nursing theory and skill development, rather than subspecialties, is viewed as the most important curricular focus. The need to continue recruiting students and develop and articulate the knowledge base in Mental Health Nursing through research and theory development is critical.
Faculty Practice: Nurse Educators' Views and Proposed Models
Authors: Just Gloria , Adams Eda , DeYoung Sandra 
Published: April 2021

ABSTRACT
Faculty practice is an issue that has been extensively debated, yet no consensus about its definition, purposes, or implementation has yet been achieved among nurse educators. This nationwide survey of a random sample of 909 AD and BSN educators was designed to elicit concepts of faculty practice and to find how and why faculty are implementing practice.
Sixty percent of the sample are practicing nursing; the reason most frequently given was to maintain clinical skills. The 40% not practicing stated lack of time as the primary reason. Responses demonstrated no differences between AD and BSN educators regarding definition, implementation, and motivation for faculty practice.
As a result of the survey, a definition of faculty practice has been formulated and conceptual models of faculty practice delineated. The models that have been developed are the Nurse-Researcher Model, Nurse-Clinician Model, and Nurse-Consultant Model.

Motivational Orientations of Registered Nurse Baccalaureate Students in Rural New England
Authors: Lethbridge Dona J 
Published: April 2021

ABSTRACT
Using Houle's learning typology, this study examined the dimensions underlying reasons RNs in rural New England return to school to obtain a baccalaureate nursing degree. Factor analysis of the Educational Participation Scale revealed eight motivational orientations. These factors differ somewhat from the study of motivations of other continuing learners, in non-credit courses and in nursing baccalaureate study in an urban area. It is suggested that more study is needed with more diverse populations to validate nurses' motivational orientations, and that consideration must be paid to whether instruments aimed at the general population of continuing learners or the specific nursing population of study are appropriate.
