A CLINICAL AND COMPARATIVE BIOMECHANICAL EVALUATION OF PROXIMAL FEMORAL OSTEOTOMY FIXATION IN CHILDREN
Authors: Greis Patrick E , Ward W Timothy , Rodosky Mark , Rudert M J , Stanitski Carl 
Published: April 2021

ABSTRACT
This study compared the biomechanical characteristics of a 90° infant blade plate construct and anteriorly applied 120° angled plate construct in response to an axial compression load. The blade plate construct stiffness was three times greater than the angled plate construct (238.9 vs 85.7 N/deg). Four degrees failure load was also significantly higher for the blade plate. Despite inferior biomechanical characteristics, the 120° angled plate functioned very satisfactorily in a retrospective clinical review of 21 proximal femoral varus osteotomies. The authors conclude that the 120° angled plate has practical benefits in terms of ease of insertion and intraoperative adjustability which may outweigh its biomechanical inferiority.
TWO-YEAR FOLLOW UP OF BIPOLAR HEMIARTHROPLASTY
Authors: Rogalski R , Huebner J , Goulet J , Kaufer H 
Published: April 2021

ABSTRACT
Forty-seven bipolar hemiarthroplasties were performed from January 1985 to December 1986. Twenty-three patients (24 hips) returned for a history, physical, and repeat radiographs. Ten primary press-fit and two cemented primary bipolar hemiarthroplasties were performed. Four patients underwent cemented and eight received press-fit revision bipolar hemiarthroplasties. Fourteen patients had simultaneous cancellous, reamed femoral head autograft, or allograft acetabular bone augmentation. Omitting one patient who had replacement for Leri's pleonosteosis, the average acetabular migration among the remaining 23 patients was 4 mm of superior and 1.5 mm of medial progression. The mean modified d'Aubigne hip score was 33 for primary press-fit arthroplasty, 30 for primary cemented arthroplasty, 22 for pressfit revisions, and 32 for cemented bipolar revision arthroplasty. Morcellized bone graft tended to variably resorb with time. Among the press-fit stems, all but two patients complained of at least occasional thigh pain. All but one patient with primary press-fit hemiarthroplasty walked with a limp. We conclude that, although good early results can be obtained, significant number of patients will have groin and thigh pain. We have found no evidence either radiologically or clinically that nonstructural bone grafting with reamed femoral head will reliably incorporate or prevent further acetabular migration.
ARTHROSCOPICALLY ASSISTED REPAIR OF ACUTE BANKART LESION
Authors: Uribe John W , Hechtman Keith S 
Published: April 2021

ABSTRACT
Acute traumatic anterior shoulder dislocations are associated with high recurrence rates in young athletic individuals. Arthroscopically assisted stabilization of acute initial traumatic anterior dislocation was carried out in 11 young athletes. The average age was 20 years, with nine males and two females. The anterior acute Bankart lesion was surgically repaired using the technique described by Caspari/Morgan. There were no surgical complications. All patients were able to return to their sport without restriction. One patient had a transient episode of instability 8 months postoperatively associated with trauma, but no further sequelae. Using the Rowe scale there were nine excellent and two good results. Using repair of a Bankart lesion provides a stable shoulder with minimal loss of function and low recurrence rate. Early intervention should be considered in young, highly competitive athletes.
CONTROVERSIES IN THE PREVENTION OF DEEP VEIN THROMBOSIS WITH TOTAL HIP ARTHROPLASTY
Authors: Fitzgerald Robert H 
Published: April 2021

ABSTRACT
Thromboembolic disease is a serious problem that is growing because both total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients are now being discharged from the hospital as early as the fourth postoperative day. The current estimate is that 50000 deaths a year in the United States can be attributed to this disease process, and it is an equally large problem in other countries such as Great Britain (Table 1).1 Thromboembolic disease is asymptomatic in the vast majority of patients undergoing joint replacement. Approximately one in six patients develops the condition following THA or TKA.
LIGAMENT RELEASE AND BONE GRAFTING IN TOTAL ARTHROPLASTY OF THE VARUS KNEE
Authors: Whiteside Leo A 
Published: April 2021

Abstract
A simplified technique is described for restoring joint line position, correcting bony defects, and achieving ligament balance in the varus knee. The thickness of the Implant is resected based on the intact surface at a predetermined 5° or 7° valgus angle. Resulting medial femoral and tibial defects are grafted with morselized cancellous autograft, and the medial ligaments are released from the tibial surface to achieve appropriate matching of varus/valgus stability. Four hundred twenty-three knees with varus deformity of 5° to 55° were followed for 2 to 7 years after surgery. Of the 98 knees with moderate varus deformity, two had grafting of minor tibial defects and none had femoral grafting. Of the 36 with severe varus deformity, three had grafting of the femoral condyle distal surface and 26 had medial tibial plateau grafting. Mean valgus angle 1 year after surgery was 5.3°, and yearly follow up revealed no tendency for deterioration of alignment Bone graft collapse was not found in any knee. Radiographic analysis of the tibial grafts routinely demonstrated trabeculation of the graft 2 years postoperatively. Mean postoperative range of motion was 111° 1 year after surgery and 115° 2 years after surgery. No major complications were found as a result of
either bone grafting or ligament release. This simplified technique of resection of the bone surfaces to match the thickness of the implant is safe and effective in the severely deformed varus knee.
THE DEVELOPMENT OF RICKETS AS A COMPLICATION OF CHEMOTHERAPY FOR THE TREATMENT OF WILMS' TUMOR
Authors: Segal Lee S , Palumbo Robert C , Robertson William W 
Published: April 2021

ABSTRACT
Musculoskeletal complaints were the presenting symptoms in four of 44 children (9%) treated for relapsed Wilms' tumors with ifosfamide, a derivative of cyclophosphamide. Subsequent radiologic examination revealed rachitic bone and joint changes. A fifth child manifested clinical and radiographic signs of rickets after presenting with hypophosphatemia, hypouricemia, and glycosuria. Recognition of a potential drug-induced Fanconi syndrome is important when managing pediatric oncology patients previously treated with ifosfamide. Early replacement therapy is recommended when proximal renal tubular abnormalities are detected to help prevent and control the severe metabolic bone disease associated with the Fanconi syndrome.
ADOLESCENT FEMORAL SHAFT FRACTURES: RIGID VERSUS FLEXIBLE NAILS
Authors: Gregory Paul , Sullivan J Andy , Herndon William A 
Published: April 2021

ABSTRACT
Twenty-one skeletally immature patients between 11 and 16 years of age were treated operatively for a unilateral femoral shaft fracture. Eleven patients underwent fixation with flexible nails and 10 with rigid nails. The patients were studied retrospectively to determine the similarity of the groups. Each method of fixation was then compared to determine the technical ease and final outcome. Both methods gave excellent final radiographic alignment with minimal complications. Flexible nailing required much less operative time and less fluoroscopy time. Estimated cost of using Ender nails is much less than using Russell-Taylor interlocking nails.
COMPRESSION PLATING OF ACUTE FEMORAL SHAFT FRACTURES
Authors: Geissler William B , Powell Thomas E , Blickenstaff Kyle R , Savoie Felix H 
Published: April 2021

ABSTRACT
Although intramedullary fixation has standardized the management of femoral shaft fractures, compression plating may offer a viable alternative. A retrospective review of acute femoral shaft fractures managed by open reduction and compression plating between 1980 and 1987 revealed 71 fractures in 69 patients. There were 58 closed fractures, and six grade I and seven grade II open fractures. All patients received prophylactic antibiotics. Sixty-nine percent of patients were bone grafted. Sixty-six of 71 fractures (93%) healed uneventfully. The average time until union was 16 weeks (range: 23 to 72). Complications included two nonunions, two refractures, and one broken implant (7%). Careful adherence to the principles of prophylactic antibiotics, medial cancellous bone grafting, and meticulous soft tissue technique can significantly reduce the complication rate of compression plating.
PERCUTANEOUS OSTEOSYNTHESIS WITH TWO SCREWS IN TREATING FEMORAL NECK FRACTURES
Authors: Poulsen Torben Dam , Ovesen Ole , Andersen Inger 
Published: April 2021

ABSTRACT
In a consecutive, retrospective study, 182 patients were followed 1 year after surgical treatment of a fractured femoral neck. The patients were admitted on alternate days to the neighboring departments of orthopedic surgery O and Ø, respectively. In Department O, the patients were submitted to sliding screw-plate (SSP) osteosynthesis, while patients in Department Ø were treated with two percutaneously introduced screws. Our results showed that double-screw osteosynthesis can be performed significantly quicker and with less blood loss than application of SSP. Healing of the fractures in the two groups did not differ significantly, nor did the cumulative rate of failure or the frequency of secondary surgical procedures. We find that, judged from these parameters, percutaneously introduced double-screw osteosynthesis is at least as effective as SSP osteosynthesis.
A COMPARISON STUDY OF TREATMENT OF THORACOLUMBAR FRACTURES USING THE ACE POSTERIOR SEGMENTAL FIXATOR AND COTREL-DUBOUSSET INSTRUMENTATION
Authors: Markel David C , Graziano Gregory P 
Published: April 2021

ABSTRACT
The results of 26 consecutive thoracolumbar fractures treated with Cotrel-Dubousset instrumentation (CDI) (n = 12) or the ACE Posterior Segmental Fixator (n = 14) with a mean follow up of 20.2 months were analyzed. Preoperatively, no statistically significant difference was noted between the two treatment groups. Postoperatively, no statistically significant difference was noted for improvement of kyphosis (mean: - 6.00° ACE, 1.92° CDI), vertebral body height (mean: 17.86% ACE, 18.83% CDI), vertebral body angle (mean: -6.21° ACE, -5.42° CDI), or estimated blood loss (mean: 1544 cc ACE, 1620 ce CDI). All patients with incomplete paraplegia improved by at least one Frankel grade. Statistically significant differences were noted in operative time (mean: 269 minutes ACE, 357 minutes CDI, P<.0005), and in the number of instrumented levels (mean: 3 ACE, 5.8 CDI). All patients exhibited solid fusion radiographically. Thoracolumbar fractures can be effectively treated by either CDI or the ACE Fixator. The ACE Fixator has the advantage of sparing motion segments and decreased operative time.
Unusual Manifestations of Proximal Tibiofibular Joint Synovial Cysts
Authors: Damron Timoy A , Rock Michael G 
Published: April 2021

ABSTRACT
Synovial cysts emanating from the proximal tibiofibular articulation are commonly symptomatic and may progress to compromise peroneal nerve function. They may cause diagnostic confusion when they present as intraosseous masses or as soft tissue masses causing extrinsic bony erosion. Twelve cases treated surgically are reviewed. Electromyography and nerve conduction studies were valuable in localizing the lesions to the knee when no mass was palpable. Of the six cases involving the peroneal nerve, three required loupe or microscopic dissection of the cyst from within the epineurium. Two other cases had bony changes. Magnetic resonance imaging, though not diagnostic, is valuable in planning the dissection.
Excision and Radiotherapy for Heterotopic Ossification of the Elbow
Authors: Poggi Matthew M , Thomas Bruce E , Johnstone Peter A S 
Published: April 2021

ABSTRACT
Radiotherapy has a well-defined role in prophylaxis of recurrent heterotopic ossification of the hip, but has been described infrequently in other situations. This article reports the use of excision and low-dose external beam radiotherapy in three patients with heterotopic ossification of the elbow treated between February 1995 and September 1996. Radiotherapy was delivered in a single fraction of 7-8 Gy within 48 hours postoperatively using opposed anteroposterior portals. After a median follow-up of 10.5 months, all three patients demonstrated a significant increase in range of motion without any evidence of recurrence. These results indicate adjuvant postexcision radiotherapy may be used for prophylaxis of recurrent heterotopic ossification of the elbow.
The Influence of Sterilization Method on Wear Performance of the Low Contact Stress Total Knee System
Authors: McNulty Donald E , Liao Yen-Shuo , Haas Brian D 
Published: April 2021

Abstract
Sterilization method changes to the Low Contact Stress (LCS) Total Knee System (DePuy Orthopaedics Ine, Warsaw, lnd) have resulted in progressive improvements in wear resistance. Initially, the system used the traditional gamma in air irradiation sterilization method, but was transitioned to Gas plasma sterilization. The Gas plasma technique did not introduce free radicals that subsequently oxidize with extended shelf aging found with gamma in air irradiation. This oxidation has demonstrated a significant reduction in mechanical properties leading to increased wear. The introduction of Gas plasma was also accompanied by a transition to polyethylene resins that no longer contained calcium stéarate, surmised to influence the rate of oxidation. More recently, gamma irradiation and storage of the poiyethyiene components in an essentially oxygenfree environment imparted by gamma irradiation in a vacuum foil pouch (GVF), has been shown to protect the implant from oxidation. Additionally, the GVF process imparts the beneficial effects of moderate crosslinking that has been demonstrated to improve wear resistance.
A New Resorbable Bone Void Filler in Trauma: Early Clinical Experience and Histologic Evaluation
Authors: Hinz Peter , Wolf Eduard , Schwesinger Günther , Hartelt Elisabeth , Ekkernkamp Axel 
Published: April 2021

Abstract
Six patients with traumatic bone injuries were treated by packing ultraporous ß-tricalcium phosphate (ß-TCP), a synthetic bone void filler, into defect sites using firm finger pressure. Radiographs showed new bone consolidating in treated sites after as little as 2 months. A biopsy obtained from a fractured calcaneus 9 months after surgery showed new bone growing within the ultraporous scaffold. Regions of newly mineralized bone and woven bone in the scaffold suggested that the defect site was undergoing repair. Some new bone had developed lamellar architecture. Higher radiodensity and slower resorption of ultraporous bone void filler in this human case, relative to that seen in a canine study, is attributed to slower metabolism in humans relative to dogs and to greater packing pressures used in the clinic. The histology specimen did not indicate untoward inflammatory response or significant foreign body reaction. Thus, this first human histology report supports the use of biocompatible ultraporous ß-TCP to enhance new bone formation in bone defects.
Biomechanical Testing of Bioabsorbable Cannulated Screws for Slipped Capital Femoral Epiphysis Fixation
Authors: Kroeber Markus W , Rovinsky David , Haskell Andrew , Heilmann Moira , Lotz Jeff , Otsuka Norman 
Published: April 2021

Abstract
This study compared cannulated 4.5-mm bioabsorbable screws made of self-reinforced poly-levolactic acid to cannulated 4.5-mm steel and titanium screws for resistance to shear stress and ability to generate compression in a polyurethane foam model of slipped capital femoral epiphysis fixation. The maximum shear stress resisted by the three screw types was similar (self-reinforced poly-levolactic acid 371 ±146 MPa, steel 442±43 MPa, and titanium 470±91 MPa). The maximum compression generated by both the self-reinforced poly-levolactic acid screw (68.5±3.3 N) and the steel screw (63.3±5.9 N) was greater than that for the titanium screw (3±1.4 N, P<.05). These data suggest cannulated self-reinforced poly-levolactic acid screws can be used in the treatment of slipped capital femoral epiphysis because of their sufficient biomechanical strength.
Treatment of Osteoarthritic Cartilage Lesions With Osteochondral Autograft Transplantation
Authors: Andres Brett M , Mears Simon C , Somel Deniz S , Klug Ray , Wenz James F 
Published: April 2021

Abstract
Twenty-two osteochondral autograft transplantations were performed on two types of knees: those with isolated (group 1) and multiple (group 2) degenerative cartilage lesions. At minimum 24-month follow-up, group 1 had significantly better pain relief and function than group 2 based on the Western Ontario and McMaster Universities Osteoarthritis Index and pain scores (10-point visual analog scale). Osteochondral autograft transplantation may be effective in treating knees with isolated degenerative cartilage lesions but appears contraindicated in those with multiple lesions.
Chart Reading and Anxiety Levels of Nursing Students Prior to First Interactions with Psychiatric Clients
Authors: Nieswiadomy Rose , Arnold Wilda K , Johnson Margie 
Published: April 2021

ABSTRACT
Nursing students' anxiety levels on the first day of their psychiatric clinical experience were compared between those students who were assigned to read (N =58) or not read (N =60) the client's chart prior to the first nurse-client interaction. Students' trait and state anxiety levels were measured at the beginning of the day. State anxiety levels were measured again after students were given instructions to read or not read the client's chart. Using trait and the first measure of state anxiety as covariates, there was no significant difference in the state anxiety scores between readers and non-readers. Based on anxiety theory, it was concluded that being told to read/not read the psychiatric client's record prior to the first interaction with the client, does not significantly influence the student's state anxiety level. Thus, when nurse educators are planning the psychiatric experience, they may wish to allow the student to make the decision whether to read or not read the client's chart, after being told the advantages and disadvantages of this action.
Multi-Course Sequential Learning as a Model for Content Integration: Ethics as a Prototype
Authors: Ryder Muriel B , Duckett Laura , Crisham Patricia , Caplan Arthur , Schmitz Kathy 
Published: April 2021

ABSTRACT
Multi-course sequential learning (MCSL), a model for integrating content throughout the curriculum, is described using ethics education as a prototype. In this model, content is presented via a vertical course, with units embedded in existing courses across various levels of the nursing program, which is designed to provide coherent organization of content, visibility, and accountability, and to prevent gaps and unnecessary duplication. This article describes the process of developing an Ethics MCSL, which is being implemented and evaluated with support from a three-year grant from the Fund for the Improvement of Postsecondary Education (FIPSE).
Developing Case Situations for Ethics Education in Nursing
Authors: Waithe Mary , Duckett Laura , Schmitz Kathy , Crisham Patricia , Ryden Muriel 
Published: April 2021

ABSTRACT
Developing cases for the clinical teaching of ethics can be extremely time-consuming. Often, the cases that are developed either represent unrealistic situations or mere technical puzzles rather than genuine ethical problems. This article describes how faculty at the University of Minnesota modified a simple, quick and inexpensive think tank technique, the Crawford Slip Method, for use with nursing educators to generate an extensive list of ethical issues within each clinical specialty. Selecting from these lists, faculty in each specialty developed one realistic nursing case situation to illustrate selected ethical issues. Faculty were asked to use the Alverno College criteria for designing a moral dilemma when writing their cases. Suggestions for adapting the cases for multiple uses are presented.
The Relative Influence of Identified Components of Text Anxiety in Baccalaureate Nursing Students
Authors: Howell Carol C , Swanson Sue C 
Published: April 2021

ABSTRACT
The relative influence on test anxiety of cognitive interference, self-concept, study and test-taking skills, and cumulative grade point average was investigated. Fifty-six female baccalaureate nursing students completed the following measures: Sarason's Test Anxiety Scale, Brown's Effective Study Test, Sarason's Cognitive Interference Questionnaire, and Brookover's Self-Concept of Ability Scale. Subjects also reported their cumulative grade point average (GPA). Data were analyzed through the use of correlation and stepwise multiple regression. Data analyses revealed significant negative relationships between test anxiety and the variables of academic self-concept and GPA (p < .05). Academic self-concept was the most powerful predictor of test anxiety, while GPA and cognitive interference contributed significantly but minimally to the multiple regression equation. Results support Meichenbaum and Butler's (1980) contention regarding the multidimensional nature of the test anxiety construct.
Specialization in Adult Health/Medical Surgical Nursing: What Does it Mean?
Authors: Kitchens Edeth K , Piazza Dianne E , Ellison Kathy J 
Published: April 2021

ABSTRACT
In this descriptive study, all NLN-accredited master's programs in the United States were surveyed to describe the content and form of the Adult Health/Medical Surgical (AH/MS) Nursing component of the curricula. An 82% response rate was achieved.
The study confirmed a high degree of diversity in the AH/ MS Nursing component of master's degree programs. It revealed a lack of consensus on the amount and kind of content necessary for specialization in AH/MS Nursing. Few curricula were based on an identified nursing model/ theoretical framework, although students in most programs were required to utilize a nursing model as a framework for advanced or specialty practice. The structure of class and clinical learning activities varied markedly. Ideas about graduate faculty's role in clinical instruction were dissimilar. Findings from the study could guide decision making for the AH/MS Nursing component of master's-level curricula.
Curriculum revision seems to be inherent in the nursefaculty role, yet curriculum decision making can be an onerous task. This is especially true in today's master's nursing programs where clinical specialty areas are not well defined and diversity and ambiguity abound.
As faculty members in a master's nursing program where numerous specialty areas had been developed, we became increasingly frustrated in our attempts to identify specific knowledge and skills that should be acquired by students specializing in adult health nursing. Traditionally, this rather broad specialty area has been a "catch-all" for the study of a wide variety of age groups and health alterations. In recent years, however, as nursing has attempted to keep pace with scientific and technological advances in health care, many of the areas that were once subsumed under the Adult Health/Medical Surgical (AH/MS) Nursing component of graduate nursing curricula have evolved into recognized specialties in their own right, e.g., cardiovascular, gerontology, oncology, rehabilitation, critical care, and long-term care nursing.
Given this splintering into increasingly narrow clinical specialties, what constitutes specialization in AH/MS Nursing? What content have nurse educators identified as appropriate for this broad specialty area? How is the content organized and delivered? What clinical learning experiences and skills are most germane to this specialty? The purpose of this study was to describe the form (structure) and content of the AH/MS Nursing component of master's nursing curricula.
