Innovation and Entrepreneurship: Perspectives From Orthopedic Surgery.
Campbell KJ, et al. Orthopedics. 2018.
Abstract
Orthopedic surgeons are tasked with treating complex patients while employing critical surgical skills, clinical knowledge, and new technologies. The constant inundation of information, coupled with hours in the hospital setting, provides unique perspectives on various aspects of how health care is delivered, thereby creating a milieu ripe for innovation. The rigors of an orthopedic career make it challenging for physicians to translate an idea into a great product. Through the authors’ experiences at a tertiary orthopedic practice, they review the process of taking an idea from concept to fruition. [Orthopedics. 201x; xx(x):xx-xx.].
The utility of botulinum toxin A in the repair of distal biceps tendon ruptures
Abstract
Purpose: The purpose of our study is to report the outcomes and complications in patients who underwent distal biceps tendon repair with the use of Botulinum toxin A (BoNT-A) as an adjunct to surgery.
Methods: A retrospective review of 14 patients who underwent 15 distal biceps tendon repairs was performed. All repaired tendons had their correlating muscle bellies injected intraoperatively with a mixture of 100U of BoNTA and 10 ml of normal saline.
The Use of MicroRNA Biomarkers to Distinguish Enchondroma from Low Grade Chondrosarcoma.
Abstract
Establishing a definitive diagnosis between benign enchondroma versus low grade chondrosarcoma presents a potential challenge to both clinicians and pathologists. microRNAs (small non-coding RNAs) have proven to be effective biomarkers for the identification of tumors and tumor progression. We present analysis, both array and quantitative PCR, that shows consistently and substantially increased expression of two microRNAs, miRs-181a and -138, in low grade chondrosarcomas compared with enchondromas. The data suggest these microRNAs would provide an analytical distinction between the chondrosarcoma and benign neoplasms that can be performed in formalin fixed paraffin embedded specimens.
Ultrasound findings in asymptomatic patients with modularmetal on metal total hip arthroplasty
Abstract
Objective: The use of metal-on-metal and modular total hip arthroplasty is associated with potentially serious local and systemic complications. The primary aim of this study was to identify the prevalence of a pseudotumor in asymptomatic patients with a particular metal-on-metal hip prosthesis after aminimum follow-up of 5 years using ultrasound evaluation.
Methods: We prospectively evaluated data collected from 36 asymptomatic patients who underwent implantation of a Profemur Z metal-on-metal total hip arthroplasty from January 2004 to January 2010.
Single-dose lidocaine spinal anesthesia in hip and knee arthroplasty
Abstract
Background: With the increasing interest in fast recovery and outpatient joint arthroplasty, short-acting local anesthetic agents and minimal narcotic use are preferred. Lidocaine is a fast-onset, short-duration local anesthetic that has been used for many years in spinal anesthesia. However, lidocaine spinal anesthesia has been reported to have a risk of transient neurologic symptoms (TNSs). The purpose of this study is to determine the safety and efficacy of single-dose lidocaine spinal anesthesia in the setting of outpatient joint arthroplasty.
Methods: We performed a prospective study on 50 patients who received lidocaine spinal anesthesia in the setting of outpatient hip and knee arthroplasty. All patients received a single-shot spinal injection, with 2% isobaric lidocaine along with titrated propofol sedation. We evaluated demographic data, length of motor blockage, time to ambulation, time to discharge readiness, patient-reported symptoms of TNS.
Short Versus Long Cephalomedullary Nails for Pertrochanteric Hip Fracture
Abstract
This study compared patients who underwent treatment with short or long cephalomedullary nails with integrated cephalocervical screws and linear compression. Patients with AO/OTA 31-A2 or A3 pertrochanteric fractures treated with either short (n=72) or long (n=97) InterTAN (Smith & Nephew, Memphis, Tennessee) cephalomedullary nails were reviewed. Information on perioperative measures (estimated blood loss, surgical time, and fluoroscopy time) and postoperative orthopedic complications (infection, implant failure, screw cutout, and periprosthetic femur fracture) was included.
Rivaroxaban Versus Enoxaparin for Venous Thromboembolism Prophylaxis after Hip and Knee Arthroplasty
Abstract
The oral Factor Xa inhibitor rivaroxaban (Xarelto) has been the pharmacologic agent used for venous thromboembolism(VTE) prophylaxis after primary hip and knee arthroplasty (THA/TKA) at our institution since February 2012. The purpose of our study was to compare rates of VTE and major bleeding between rivaroxaban and our previous protocol of enoxaparin after THA/TKA. A retrospective cohort studywas performed including 2406 consecutive patients at our institution between 1/1/11 and 9/30/13. Patients who did not have unilateral primary THA/TKA or who received other anticoagulants were excluded. Of the 1762 patients included, 1113 patients (63.2%) received enoxaparin and 649 patients (36.8%) received rivaroxaban. This study found no demonstrable differences between these two anticoagulants in rates of VTE, infection, reoperation, transfusion, ormajor bleeding. Therapeutic, Retrospective comparative study, Level III.
Reconsidering the Affordable Care Act’s Restrictions on Physician-Owned Hospitals
Concerns about financial incentives and increased costs prompted legislation limiting the expansion of physician-owned hospitals in 2010. Supporters of physician-owned hospitals argue that they improve the value of care by improving quality and reducing costs. The purpose of the present study was to determine whether physician-owned and non-physician-owned hospitals differ in terms of costs, outcomes, and patient satisfaction in the setting of total hip arthroplasty (THA) and total knee arthroplasty (TKA).
Predictors and Complications of Blood Transfusion in Total Hip and Knee Arthroplasty
Abstract
Perioperative patient optimization can minimize the need for blood transfusions in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to determine predictors and complications of transfusions. This retrospective review analyzed 1795 patients who underwent primary THA and TKA at our institution between January 2011 and December 2012. Of the 1573 patients ultimately included the rates of transfusion were 9.27% in TKA and 26.6% in THA. Significant predictors for transfusion include: preoperative hemoglobin, age, female gender, body mass index, creatinine, TKA, operating room time, operative blood loss, and intra-operative fluids. The DVT rate was comparable, but deep surgical site infection rate among transfused patients was 2.4% compared to 0.5% in non-transfused patients (P = 0.0065).
Outcomes of Ankle Fractures in Patients with Uncomplicated Versus Complicated Diabetes
Abstract
Background: Patients with diabetes who sustain an ankle fracture are at increased risk for complications including higher rates of in hospital mortality, in-hospital postoperative complications, length of stay and non-routine discharges. The purpose of this study was to retrospectively compare the complications associated with operatively treated ankle fractures in a group of patients with uncomplicated diabetes versus a group of patients with complicated diabetes. Complicated diabetes was defined as diabetes associated with end organ damage such as peripheral neuropathy, nephropathy and/or PAD. Uncomplicated diabetes was defined as diabetes without any of these associated conditions. Our hypothesis was that patients with uncomplicated diabetes would experience fewer complications than those patients with complicated diabetes.
Methods: We compared the complication rates of ankle fracture repair in 46 patients with complicated diabetes and 59 patients with uncomplicated diabetes and calculated odds ratios (OR) for significant findings. Results: At a mean followup of 21.4 months we found that patients with complicated diabetes had 3.8 times increased risk of overall complications 3.4 times increased risk of a non-infectious complication (malunion, nonunion or Charcot arthropathy) and 5 times higher likelihood of needing revision surgery/arthrodesis when compared to patients with uncomplicated diabetes.
Intraoperative Periprosthetic Femur Fracture: A Biomechanical Analysis of Cerclage Fixation
Intraoperative periprosthetic femur fracture is a knowncomplication of total hip arthroplasty (THA) and a variety of cerclage systems are available to manage these fractures. The purpose of this study was to examine the in situ biomechanical response of cerclage systems for fixation of periprosthetic femur fractures that occur during cementless THA. We compared cobalt chrome (CoCr) cables, synthetic cables, monofilament wires and hose clamps under axial compressive and torsional loading. Metallic constructs with a positive locking system performed the best, supporting the highest loads with minimal implant subsidence (both axial and angular) after loading. Overall, the CoCr cable and hose clamp had the highest construct stiffness and least reduction in stiffness with increased loading. They were not demonstrably different from each other.
The stability of dual-taper modular hip implants: a biomechanical analysis examining the effect of impact location on component stability
Abstract
Background: The purpose of this study was to investigate the stability of dual-taper modular implants following impaction forces delivered at varying locations as measured by the distraction forces required to disassemble the components.
Methods: Distraction of the head-neck and neck-stem (NS) tapers of dual-taper modular implants with 0°, 8°, and 15° neck angles were measured utilizing a custom-made distraction fixture attached to a servohydraulic materials test machine. Distraction was measured after hand pressing the components as well as following a simulated firm hammer blow impaction. Impacts to the 0°, 8°, 15° necks were directed axially in line with the neck, 10° anterior, and 10° proximal to the axis of the neck, respectively.
The Effect of Impact Location on Force Transmission to the Modular Junctions of Dual-Taper Modular Hip Implants
Abstract
Background: The purpose of this study was to investigate the effect that off-axis impaction has on stability of dual-taper modular implants as measured by forces delivered to and transmitted through the head-neck and neck-stem tapers, respectively.
Methods: One hundred forty-four impact tests were performed using 6 different directions: one on-axis and five 10° off-axes. Four different simulations were performed measuring the head-neck only and 3 different neck angulations: 0°, 8°, and 15°. A drop tower impactor delivered both on - and off-axis impaction from a constant height. Load cells positioned in the drop mass and at the head-neck or neck-stem junction measured the impact and joint forces, respectively.
The Athlete’s Spine - Lumbar Herniated Nucleus Pulposus
Lumbar herniated nucleus pulposus is common among athletes given the physical stresses placed upon the lumbar spine with various athletic activities. Although the natural course is generally favorable with conservative management, there producible success of lumbar discectomy provides itself as an alternative treatment option for the athlete. Both conservative and operative management are associated with quick recovery and return to play. This chapter reviews the natural history of lumbar herniated nucleus pulposus, various treatment modal- ities, and the athlete - specific metrics pertinent to the management of athletes.
Ewing Sarcoma in the Fifth Metacarpal of an Adult Woman
Abstract
Atypical presentations of Ewing sarcoma (ES) can lead to misdiagnosis and delays in treatment. We present a rare case of ES in the hand of an adult woman who underwent multiple interventions prior to referral to our institution. At 22 months after definitive treatment, the patient remained pleased with the result and had no evidence of recurrence.
Effect of Body Mass Index on Blood Transfusion in Total Hip and Knee Arthroplasty
Abstract
Perioperative blood management remains a challenge during total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to systematically examine the relationship between body mass index (BMI) and perioperative blood transfusion during THA and TKA while attempting to resolve conflicting results in previously published studies. The authors retrospectively evaluated 2399 patients, 896 of whom underwent THA and 1503 of whom underwent TKA. Various outcome variables were assessed for their relationship to BMI, which was stratified using the World Health Organization classification scheme (normal, < 25 kg/m2; overweight, 25-30 kg/m2; obese, >30 kg/m2).
Do higher-volume hospitals provide better value in revision hip and knee arthroplasty?
We questioned the Centres for Medicare and Medicaid Services (CMS) Inpatient Charge Data and identified 789 hospitals performing a total of 29 580 revision arthroplasties in 2014. Centres were dichotomised into high-volume (performing over 50 revision cases per year) and low-volume. Mean total hospital-specific charges and inpatient payments were obtained from the database and stratified based on Diagnosis Related Group (DRG) codes. Patient satisfaction scores were obtained from the multiyear CMS Hospital Compare database.
Intraoperative Hypothermia During Surgical Fixation of Hip Fractures
Abstract
Hip fractures are common orthopedic injuries and are associated with significant morbidity/mortality. Intraoperative normothermia is recommended by national guidelines to minimize additional morbidity/mortality, but limited evidence exists regarding hypothermia’s effect on orthopedic patients. The purpose of this study was to determine the incidence of intraoperative hypothermia in patients with operatively treated hip fractures and evaluate its effect on complications and outcomes. Retrospective chart review was performed on clinical records from 1541 consecutive patients who sustained a hip fracture and underwent operative fixation at the authors’ institution between January 2005 and October 2013. A total of 1525 patients were included for analysis, excluding those with injuries requiring additional surgical intervention.
Intraoperative chlorhexidine irrigation to prevent infection in total hip and knee arthroplasty
Abstract
Background:Surgical site irrigation during total hip (THA) and total knee (TKA) arthroplasty is a routine practice among orthopaedic surgeons to prevent periprosthetic joint infection. The purpose of this study was to evaluate the effect of chlorhexidine gluconate (CHG) irrigation on infection rates following THA and TKA.
Methods: Arthroplasties performed before September 2014 served as controls. THA performed before September 2014 (N ¼ 253) underwent intraoperative irrigation with 0.9% saline followed by a 2-minute soak with < 2% dilute povidone-iodine. TKA (N ¼ 411) patients underwent only intraoperative saline irrigation. After October 2014, all patients (248 TKA and 138 THA) received intraoperative irrigation with 0.9% saline and periodic 0.05% CHG solution followed by a final 1-minute soak in CHG with immediate closure afterward.

Improving Value in Total Hip and Knee Arthroplasty: The Role of High Volume Hospitals
Abstract
Background: Recent healthcare reform efforts have focused on improving the quality of total joint replacement care while reducing overall costs. The purpose of this study is to determine if higher volume centers have lower costs and better outcomes than lower volume hospitals.
Methods: We queried the Centers for Medicare and Medicaid Services (CMS) Inpatient Charge Data and identified 2702 hospitals that performed a total of 458,259 primary arthroplasty procedures in 2014. Centers were defined as low (performing < 100 total joint arthroplasty [TJA] per year) or high volume and mean total hospital-specific charges and inpatient payments were obtained. Patient satisfaction scores as well 30-day risk-adjusted complication and readmission scores were obtained from the multiyear CMS Hospital Compare database.
Hypersensitivity: “Doc, Am I Allergic to My Implant?”
Abstract
There is controversy regarding the clinical significance of metal hypersensitivity in total knee arthroplasty(TKA). Given the current state of the art, metal hypersensitivity, if it exists at all, is a diagnosis of exclusion. Clinical presentation may involve acutaneous response, but current diagnostic methods do not have robust clinical validation and should be used with caution. The two most commonly used tests include cutaneous patch testing and in vitro lymphocyte transformation testing. Initially, conservative management is indicated and other more common causes of asymptomatic total knee replacement should be fully explored. In rare cases, device removal maybe undertaken but this should be considered a last resort. Pre-operative testing prior to a primary total joint replacement may be helpful whenthere′s a patient - reported history of intolerance to jewelry or of an allergic reaction to a prior metal implant, but routine lab screening is not supported by the literature.
Heterotopic Ossification Prophylaxis After Total Hip Arthroplasty: Randomized Trial of 400 vs 700 cGy
Abstract
Background: Heterotopic ossification (HO) is a known complication following total hip arthroplasty. Radiation is an effective prophylaxis, but an optimal protocol has yet to be determined. We performed a randomized, double-blinded clinical trial in high-risk patients to determine the efficacy of 400 vs 700 cGy doses of radiation.
Methods: One hundred forty-seven patients undergoing total hip arthroplasty and at high risk for HO at an urban medical center were randomized to receive either a single 400 or 700 cGy dose of radiation postoperatively. High risk was defined as a diagnosis of diffuse idiopathic skeletal hyperostosis, hypertrophic osteoarthritis, ankylosing spondylitis, or history of previous HO. Radiation was administered on the first or second postoperative day. A single blinded reviewer graded radiographs taken immediately postoperatively and at a minimum of 6 months postoperatively using the Brooker classification. Progression was defined as an increase in Brooker classification. Operative data including surgical approach, implant fixation, revision surgery, and postoperative range of motion data were also collected.
