Authors: Lee Sang Hoon , Kim Han-Soo , Kim Sang Rim , Park Yong-Bum , Yoo Kwang Hyun , Lee Han Koo 
Published: April 2021

ABSTRACT
Thirty-eight patients treated surgically for metastatic tumors of the femur were reviewed to evaluate the effects of surgical treatment on quality of life. Average age at surgery was 59 years. The most common origin site of metastatic tumors was the lung. The intertrochanteric area was involved in 14 patients, followed by the subtrochanteric area in 1 1 , femoral neck in 7, and shaft in 6 patients. Surgery was based on the principles that tumor excision should be maximal, and to permit early postoperative ambulation, internal fixation should be rigid with cement augmentation. Types of internal fixation were applied according to lesion site to allow early ambulation and included intramedullary nailing (1 1 ), compression hip screw (9), and Rowe plates (7). Prosthetic replacement was performed in 9 patients.
Average performance scores improved from 3.8 preoperatively to 2 postoperatively, based on the Functional Classification of the New York Heart Association. In 31 patients (82%), the degree of pain relief was more than a lot according to the criteria of Kaiko. Thirty-five patients survived >5 months postoperatively. In patients with a single metastatic lesion, survival was 21 months, and in patients with multiple lesions, survival was 10 months. Surgical stabilization of a pathologic lesion involving the femur resulted in improvement in the quality of life, including pain relief and early ambulation. In selected patients with a single metastatic lesion and a low-grade primary tumor, prolonged postoperative survival may be expected.
Musculoskeletal Complications of Crohn's Disease: The Role of Computed Tomography in Diagnosis and Patient Management
Authors: Brenner Howard I , Fishman Elliot K , Harris Mary L , Bayless Theodore M 
Published: April 2021

ABSTRACT
The delayed diagnosis of musculoskeletal complications of Crohn's disease may produce major morbidity in patients. This study compared abdominal and pelvic computed tomography (CT) with conventional radiography in the diagnosis of musculoskeletal complications in 23 of 552 patients with Crohn's disease examined by CT over a 7-year period. Surgical confirmation was available in 15 of 21 patients. The clinical features of psoas/gluteal abscesses, abdominal wall fistulae, and sacral osteomyelitis are described. Because the clinical manifestations of these musculoskeletal complications are often nonspecific, CT is often useful in diagnosing and directing therapeutic interventions.
Anatomical Variation of the Posterior Interosseous Nerve: A Cadaver Dissection Study
Authors: Seradge Houshang , Tian Wen , Baer Carrie , Seradge Ali 
Published: April 2021

ABSTRACT
An anatomical variation of the posterior interosseous nerve was found in a cadaver. The posterior interosseous nerve entered the supinator muscle 3 cm distal to the radiohumeral joint, but exited from two sites. Fifty percent of the nerve exited under the distal edge of the supinator muscle. The other 50% of the nerve pierced through the supinator muscle, 4.2 cm distal to the articular surface of the radial head and then joined the remaining posterior interosseous nerve as it emerged from the supinator muscle distally. Variations were not found concerning the order and the manner of branches to the muscles. This variation in the posterior interosseous nerve could be an additional compression site for this nerve and therefore responsible for some of the atypical presentations of symptoms and for partial recovery after surgical decompression. Careful surgical dissection is recommended to avoid injury to this branch.

Authors: David Rami , Shtarker Haim , Horesh Zvi , Tsur Atzmon , Soudry Michael 
Published: April 2021

ABSTRACT
Thirteen patients with failed total knee arthroplasty (TKA) due to infection (1 2 patients) or aseptic loosening (1 patient) underwent arthrodesis using the Ilizarov external fixator. Solid fusion was achieved in afi patients with an average healing time of 27.6 weeks. Patients spent an average 1 8.8 weeks in the fixator followed by an average 8.8 weeks in a plaster cylinder cast. Five patients had a pin tract infection and one a superficial wound infection. One patient had 1 5° recurvatum after surgery that was gradually corrected by adding a hinge system to the fixator. Average shortening of the affected limb was 3.7 cm (range: 1-6 cm). The Uizarov fixator for knee arthrodesis after failed TKA produced favorable results and should be considered for use by surgeons familiar with the technique.

Published: April 2021

ABSTRACT
The effect of recombinant human erythropoietin on autologous blood donation was investigated in 73 rheumatoid arthritis patients who underwent hip or knee arthroplasty. Autologous blood donation of 400 mL was successful with recombinant human erythropoietin (12,000 U per week), and no homologous blood was required. The mean period of blood collection was 33.8 days. Mean hemoglobin levels were 9.7 g/dL before treatment, 10.7 g/dt before surgery, and 10.2 g/dL after surgery. This study confirmed recombinant human erythropoietin is effective for enabling preoperative blood donation in rheumatoid arthritis patients.
Anatomic Considerations of the Posterolateral Lumbar Disk Region
Authors: Gu Yaoming , Ebraheim Nabil A , Xu Rongming , Rezcallah Anthony T , Yeasting Richard A 
Published: April 2021

ABSTRACT
Sixteen embalmed cadavers were dissected to determine the location of the lumbar nerve root and sympathetic trunk with reference to the superior border of transverse process. In the posterolateral lumbar disk region, a safe zone was found between the anterior limit of the lumbar nerve and the posterior limit of the sympathetic trunk. It has a transverse dimension of 22 mm at the T12-L1 disk region and 25 mm at the L4-L5 disk region. The only exception to this was the genitofemoral nerve running close to the lateral margin of the L2-L3 disk. The study provides an understanding of the posterolateral orientation of the lumbar nerves and sympathetic trunk.
Evaluation of Knee Consultations to a Referral-Only Orthopedic Clinic in a Managed Care System
Authors: Rupp Robert E 
Published: April 2021

ABSTRACT
One hundred sixty-five knee consultations to a referralonly orthopedic service over a 2-year period were reviewed to document the gatekeeper diagnosis and initial treatment plan. These data were compared to the orthopedic evaluation. The majority of gatekeeper referral diagnoses were nonspecific or inaccurate. Several misdiagnoses resulted in prolonged patient recovery (delayed quadriceps tendon repair) and reinjury (recurrent instability of unrecognized anterior cruciate ligament-deficient knees). These findings suggest the gatekeeper model may be inadequate to appropriately manage knee disorders.
Failed Surgical Management of Partial Thickness Rotator Cuff Tears
Authors: Miller Suzanne L , Hazrati Yassamin , Cornwall Roger , Hayes Patrick , Gothelf Todd , Gladstone James L , Flatow Evan L 
Published: April 2021

Abstract
Some authors have recommended that rotator cuff tears <50% of tendon thickness be debrided and those involving >50% of the tendon be treated with miniopen repair. We hypothesize that if indications for selecting between simple debridement and tendon repair were appropriate, then both groups should have comparable outcomes. Thirty-nine patients with partial rotator cuff tears met inclusion criteria and were available for retrospective analysis. Twenty-six percent of patients who underwent debridement and 12.5% of patients who had mini-open repair had unsatisfactory results according to Neer's criteria.
Long-Term Results of Derotational Femoral Varus Osteotomy in Legg-Calvé-Perthes Disease: 26-Year Follow-Up
Authors: Than Peter , Halmai Vilmos , Shaikh Shoaib , Kránicz János , Bellyei Árpád 
Published: April 2021

Abstract
The long-term results of 30 patients (31 hips) who underwent derotational femoral varus osteotomy for Legg-Calvé-Perthes disease are presented. Pain, leg-length discrepancy, Trendelenburg sign, and range of motion at the operated hip were examined clinically. Radiographic analysis included measurement of the Wiberg angle, epiphyseal index, acetabular index, and the Mose index. All were found to be satisfactory for patients in the good/fair category. Good/fair results were obtained in 27 (87%) of 31 hips according to Catterall's postoperative classification. Four patients were classified in the poor category due to severe restriction of movement and constant hip pain. Therefore, derotational femoral varus osteotomy is recommended for the treatment of patients with Legg-Calvé-Perthes disease.
Interscalene Block for Elective Shoulder Surgery
Authors: Conroy Brian P , Gray Bruce C , Fischer Robert B , Del Campo Lewis J , Kenter Keith 
Published: April 2021

Abstract
This study assessed patient experiences with interscalene block anesthesia for elective shoulder surgery. Routine use of interscalene anesthesia was introduced at our institution in 1997. All patients who underwent interscalene anesthesia during the first 3 years of our experience with this regional anesthetic technique were asked to respond to an anesthesia-related questionnaire. Overall patient satisfaction with interscalene anesthesia was 87%, and success rate in achieving a complete motor and sensory block was 79%. The duration of pain relief postoperatively was 10.5 hours for patients with a successful block. Patients consistently reported that having an interscalene block was less painful than anticipated; 90% said they would have interscalene anesthesia again for shoulder surgery. This study demonstrates that interscalene anesthesia for elective shoulder surgery is safe and well accepted in this patient population.
Healing of Large Defects Treated With Calcium Sulfate Pellets Containing Demineralized Bone Matrix Particles
Authors: Urban Robert M , Turner Thomas M , Hall Deborah J , Infanger Susan , Cheema N , Lim T-H 
Published: April 2021

Abstract
Calcium sulfate (OsteoSet, Wright Medical Technology, Inc, Arlington, Tenn) and calcium sulfate/demineralized bone matrix (DBM) pellets (OsteoSet DBM, Wright Medical Technology, Inc) have been evaluated preclinically in a bilateral medullary defect model of a canine humerus. In this model, both short (6 week) and long (26 week) time points have been evaluated. An analysis of bone response to the pellets was conducted using radiological, histological, mechanical, and quantification techniques. The calcium sulfate/DBM pellets exhibited more rapid trabecular bone remodeling as demonstrated by the absence of the ringlet bone structure typically seen with calcium sulfate pellets. We concluded that calcium sulfate and calcium sulfate/DBM pellets are both effective bone graft substitutes.
Diskography Outcomes in Patients Following Lumbar Diskectomy
Authors: Siambanes David , Kposowa Augustine J , Michelsen Steven 
Published: April 2021

Abstract
The results of lumbar diskography at post-diskectomy and nonoperative disk levels in postoperative patients and patients without prior back surgery were reviewed over 3 years. Other possible predictive factors, including disk degeneration (per the Adam's classification), end-point resistance, gender, and age, also were reviewed. The results revealed that no statistically significant association was noted between the presence of a prior diskectomy and the outcome of diskography. However, disk degeneration classified as ruptured and fissured correlated statistically with positive diskography. Additionally, age between 30 and 39 years and male gender were statistically associated with a positive diskogram. Disk levels displaying a poor end point during diskography injection (not amendable to pressurization) were statistically related to ruptured or fissured disk levels and thus positive diskography. Based on these results, the assumption that disabling low-back pain presenting after lumbar procedure is due to diskogenic disease arising from the surgical level is not supported.
Advanced Navigation Planning Including Soft Tissue Management
Authors: Clemens Ulrich , Miehlke Rolf Klaus 
Published: April 2021

abstract
The OrthoPilot TKA Version 4.2 (B. Braun-Aesculap, Tuttlingen, Germany) offers software support for orthopedic surgeons. The system provides nearly normal manual workflow, creates perfect cuts, allows for sophisticated management of soft tissue, and respects individual anatomies. The OrthoPilot TKA Version 4.2 displays information to guide surgical decisions. However, surgeons decide if the information will be used during the resection. The most important advancements in the Version 4.2 software are the calculation of perfect rotation of the femoral component and optimal gap balancing.
Computer-Assisted Two-Dimensional Preoperative Planning for Total Hip Arthroplasty: Clinical Evaluation
Authors: Jolles B M , Leyvraz P-F 
Published: April 2021

abstract
The purpose of this study is to clinically validate a new two-dimensional preoperative planning software for cementless total hip arthroplasty (THA). Manual and two-dimensional computer-assisted planning were compared by an independent observer for each of the 30 patients with osteoarthritis who underwent THA. This study showed that there were no statistical differences between the results of both preoperative plans in terms of stem size and neck length (<1 size) and hip rotation center position (<5 mm). Two-dimensional computer-assisted preoperative planning provided successful results comparable to those using the manual procedure, thereby allowing the surgeon to simulate various stem designs easily.

abstract
We measured the carrying angle using a universal full-circle manual goniometer on the dominant and non-dominant extremity of the elbow in 1275 healthy volunteers (631 males, 644 females) with a mean age of 22.87±15.99 years range: 2-91 years). In the right arm dominant group, right carrying angle was 11.25°±3.73° and left carrying angle was 10.57°±3.63Q (P-COOl). In left arm dominant group, right carrying angle was 1Q.65°±3.99D and left carrying angle was 12.93°±4.22° (P<.0()1). The carrying angle of dominant arm was found to be significantly higher than the non-dominant arm in both sexes. The carrying angle of dominant and non-dominant arms were found to lie significantly higher in patients aged >14 years than that of patients aged ^14 years; females ranked higher than males.
The Effect of an Extended Flexor Carpi Radialis Approach on Blood Flow to the Distal Radius: A Cadaveric Study
Authors: Placzek Jeffrey D , Sobol Gregory V , Arnoczky Steven P , Quinn Michael , Magnell Thomas 
Published: April 2021

abstract
The effect of an extended flexor carpi radialis approach on the blood supply of the radius was examined in six (3 paired) fresh frozen cadaver limbs after injection with India ink and clearing using a modified Spalteholz technique. An extended flexor carpi radialis approach to the distal radius was made in the left limb in each of the three-paired limbs. The right limb served as a nonoperative control. Following perfusion of the arterial vasculatureof each limb with India ink, serial transverse sections were cut and the intraosseous blood supply evaluated using a modified Spalteholz technique. Both controls and surgical specimens demonstrated compíete cortical penetration from endosteal vessels in the proximal and midsectionsof the radius. In the distal radius, surgical specimens demonstrated reduced perfusion volarly, however there continued to be perfusion of ink through intact dorsal and ulnar metaphyseal perforating arteries. Persistent vascular perfusion to the distal radius remains through intact endosteal vessels and metaphyseal perforators of extensive surgical soft-tissue stripping.
Acetabular Reconstruction in Revision Hip Surgery Using Femoral Head Block Allograft
Authors: Piriou Philippe , Norton Mark , Marmorat Jean-Luc , Judet Thierry 
Published: April 2021

abstract
This prospective study analyzed the clinical and radiological results of 140 consecutive cases of acetabular revision using large frozen femoral head allografts and cemented all -polyethylene acetabular components. Mean follow-up was 10 years (range: 5-16 years). Thirty patients died, seven were lost to follow-up, and 26 had failed and undergone further surgery. Nineteen failures were due to aseptic failure and collapse of the graft. Kaplan-Meier survival analysis calculated a mean survival at 1 0 years of 88.5% for revision for any reason. We compared all reported techniques of acetabular reconstruction for similar defects and recommend a surgical strategy based on the available evidence, but weighted towards a preference to reconstitute bone stock rather than removing further bone in the revision situation.
Legal Implications of Academic Dismissal and Educational Malpractice for Nursing Faculty
Authors: Goclowski Jadwiga 
Published: April 2021

ABSTRACT
Recent legal decisions affect nursing education not only in the area of academic dismissal but also in the area of educational malpractice. Nursing faculty may be caught in an interesting "catch-22" phenomenon. There exists a possibility where an educator may be sued for both failing, and not failing, a student. An incompetent graduate may sue for inadequate education, and a dismissed student may sue the faculty member for failing to treat the student in a logical and reasonable manner.
Although courts have recognized that faculty members are uniquely qualified to observe and judge all aspects of their students' academic performance, nursing instructors have a double responsibility; one to the client and the other to the student. Clinical nursing faculties must meet a standard of care with respect to the client and a standard of conduct with respect to the student.

Published: April 2021

ABSTRACT
In an attempt to address the question of what activities should be considered scholarly, thereby warranting their inclusion in a nursing faculty evaluation model, a study was undertaken which surveyed all National League for Nursing accredited baccalaureate educational programs.
The items in the instrument were generated utilizing the Delphi method and a pilot study established inter-respondent reliability. A response rate of 73% was attained.
Scholarly activity was considered highly important in evaluation for promotion and tenure in over 50% of the schools. There were distinct differences in the activities deemed scholarly when respondents were broken down into categories such as size and type of institution and the existence or non-existence of graduate nursing programs in the same institution.

Published: April 2021

ABSTRACT
This exploratory study was designed to begin analysis on the "Faculty Work Plan" and its potential for faculty role development in a university setting. The specific goals were: (1) to identify the degree of congruence between faculty work plans and the school goals; and (2) to determine the relationship between faculty work plan/school goal congruence, faculty productivity, potency, and job satisfaction.
The sample was composed of 26 respondents, 26 to 50 years old, from a pool of 48 full-time faculty members affiliated with a school of nursing in a university setting. Likerttype rating scores were used to measure Faculty Work PlanSchool Goal Congruence (FWP-SG), job satisfaction, productivity, and potency. Data analyses were focused on frequency distribution, group means, and Pearson Correlation Coefficients on selected pairs of variables. Interesting findings were revealed. A strong relationship was found between FWP-SG congruence and faculty productivity (r = .85; p= .000) and potency (r = .84; p= .000). Several recommendations were suggested.
Meeting the Terminal Functions of a Baccalaureate Curriculum: The Students' Perception
Authors: Moore Linda , Boyd Marlyn D 
Published: April 2021

ABSTRACT
Nursing faculty have established terminal functions which graduates are expected to be able to accomplish after successfully completing the nursing program. Students have asked themselves and faculty if they are ready to perform as professional nurses after graduation. This study utilized the terminal functions established by one mediumsize state university to obtain data regarding the students' perceptions of their competencies based on the terminal functions. The assessment was conducted at the time of graduation and again one year post-graduation. The data may provide other faculty with a method to further evaluate nursing curricula and illustrate the changes in graduates' perceptions of their abilities over time.
The Relationship of Nursing Deans' Leadership Behaviors With Institutional Characteristics
Authors: Lucas Mary D 
Published: April 2021

ABSTRACT
The purpose of this study was to investigate the relationships between the leadership behaviors of nursing deans and selected organizational variables in baccalaureate and higher degree nursing programs in the United States. The sample consisted of 170 deans who provided data on their self-perceived leadership behaviors as measured by the Leadership Behavior Description Questionnaire and on institutional characteristics of both their nursing programs and parent institutions. Using correlation and analysis of variance, a significant relationship was found between the leadership dimension of Consideration and faculty expertise. Significant relationships were also found between the dimension of Initiating Structure and the nursing program variables of faculty expertise and educational task and the parent institution variables of control, educational task, and size. This study proposes that organizational variables should be included in leadership theory for nursing academic administrators.
