The use of clinical reasoning skills in the setting of uncertainty: Trial femoral head migration.

Anat Sci Educ 2019 Feb 14. Epub 2019 Feb 14.

Department of Human Anatomy, School of Medicine, Universidad Autónoma de Nuevo León, Monterrey, México.

Clinical skills and medical knowledge enable physicians to overcome the uncertainty of emergent and rare clinical scenarios. Recently, a growing emphasis on evidence-based medicine has flooded medical curricula of universities across the globe with guideline-based material, and while it has given teachers and students new tools to improve medical education, clinical reasoning must be reaffirmed in its capacity to provide physicians with the ability to solve unexpected clinical scenarios. Anatomical education in medical school should have two main objectives: to acquire anatomical knowledge, and to develop the skill of applying that knowledge in clinical scenarios. Read More

A Preoperative Workup of a "Hip-Spine" Total Hip Arthroplasty Patient: A Simplified Approach to a Complex Problem.

J Arthroplasty 2019 Jan 18. Epub 2019 Jan 18.

Adult Reconstruction and Joint Replacement Service, Hospital for Special Surgery, New York, NY.

Background: A large body of evidence has confirmed that patients with spinal deformity, lumbar fusion, and abnormal spinopelvic mobility are at significantly increased risk for instability, dislocation, and revision after total hip arthroplasty (THA).

Methods: Achieving a stable construct in patients with pre-existing spine disease requires an understanding of basic spinopelvic parameters and the compensatory mechanisms associated with abnormal spinopelvic motion. Indicated patients with concomitant hip-spine pathology should be assessed for (1) the presence of spinal deformity and (2) the presence of spinal stiffness before undergoing THA. Read More

[Challenges of primary hip arthroplasty with high hip dislocation].

Orthopade 2019 Feb 6. Epub 2019 Feb 6.

Klinik und Poliklinik für Orthopädie, Unfallchirurgie und Plastische Chirurgie Bereich Endoprothetik/Orthopädie, Universitätsklinik Leipzig AöR, Liebigstr. 20, 04103, Leipzig, Deutschland.

Background: Endoprosthetic care of high hip dislocation is a surgical challenge. The hip anatomy is greatly altered in these patients, including a rather flat and small acetabulum with impaired bone quality and a relevant chance of a bony defect of the acetabular roof. Additionally, the front coverage and in some cases even the dorsal coverage of the hip are missing. Read More

Downregulation of ABCB1 gene in patients with total hip or knee arthroplasty influences pharmacokinetics of rivaroxaban: a population pharmacokinetic-pharmacodynamic study.

Eur J Clin Pharmacol 2019 Feb 6. Epub 2019 Feb 6.

Faculty of Pharmacy, University of Ljubljana, Aškerčeva cesta 7, 1000, Ljubljana, Slovenia.

Purpose: Rivaroxaban is a substrate for ABCB1 transporter and is commonly used in patients undergoing hip or knee replacement surgery for thromboprophylaxis. The objective of this study was to develop a population pharmacokinetic-pharmacodynamic (PK-PD) model to investigate the influence of ABCB1 gene expression and polymorphism on rivaroxaban exposure and anticoagulation effects.

Methods: Five blood samples per patient were collected during 5 days after the surgery for the determination of rivaroxaban concentration in plasma and for determination of prothrombin time and partial thromboplastin time. Read More

[Intraprosthetic luxation of trapeziometacarpal joint prosthesis].

Ugeskr Laeger 2019 Jan;181(5)

Total joint replacement is used for treating osteoarthritis of the trapeziometacarpal joint. The prosthesis is a ball and socket design resembling a total hip prosthesis and with the same risk of head luxation. To reduce this risk, dual mobility articulations have also been introduced in prosthesis of the thumb, and this is a case report of luxation of the polyethylene liner in a dual mobility prosthesis, illustrating that introducing new designs in prosthesis for the basal joint of the thumb may lead to similar complications as are seen in the hip joint.

Effect of anatomical variability on stress-shielding induced by short calcar-guided stems: Automated finite element analysis of 90 femora.

J Orthop Res 2019 Feb 5. Epub 2019 Feb 5.

Biomechanics Section, KU Leuven, Celestijnenlaan 300C, 3001 Leuven, Belgium.

Short stem hip implants are becoming increasingly popular since they preserve bone stock and presumably reduce stress-shielding. However, concerns remain whether they are suitable for a wide range of patients with varying anatomy. The aim of this study was to investigate how femoral anatomy influences stress-shielding induced by a short calcar-guided stem across a set of 90 CT-based femur models. Read More

Perioperative Cardiac Troponin I Levels in Patients Undergoing Total Hip and Total Knee Arthroplasty: A Single Center Study.

Anesth Pain Med 2018 Dec 19;8(6):e84228. Epub 2018 Nov 19.

Tabriz University of Medical Sciences, Tabriz, Iran.

Background: Cardiac injury is one of the significant perioperative complications in major orthopedic surgeries and its early diagnosis is useful in the reduction of postoperative comorbidity. The cardiac troponin is a sensitive and specific biomarker for detecting this damage.

Objectives: The aim of this study was to evaluate the levels of perioperative cardiac troponin I (cTnI) before and after arthroplasty in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). Read More

Simplifying the Hip-Spine Relationship for Total Hip Arthroplasty: What Do I Need to Do Differently Intraoperatively?

J Arthroplasty 2019 Jan 10. Epub 2019 Jan 10.

Chief, Adult Reconstruction and Joint Replacement, Hospital For Special Surgery, New York, NY.

As our recognition of the complexity of the hip-spine relationship is based on stability, there are several intraoperative strategies that surgeons may consider. First, patient positioning on the operative table plays an important role in reducing pelvic motion and tilt. Then, consider determining the femoral version before acetabular preparation and component insertion. Read More

Tranexamic Acid Reduces Transfusion Rates in Obese Patients Undergoing Total Joint Arthroplasty.

Surg Technol Int 2019 Feb 1;34. Epub 2019 Feb 1.

BronxCare Hospital Center, Bronx, New York.

Background: While tranexamic acid (TXA) has been well shown to reduce blood loss after joint replacement surgery, little is known regarding its effectiveness in obese patients. The aim of this study was to evaluate the effect of TXA changes in hematocrit and hemoglobin levels as well as incidence of packed red blood cell (pRBC) transfusions in obese patients undergoing total joint arthroplasty (TJA).

Material And Methods: Between January 2014 and May 2015, 420 consecutive primary joint replacements were performed by two surgeons at our institution. Read More

Performance Of Safety-Net Hospitals In Year 1 Of The Comprehensive Care For Joint Replacement Model.

Health Aff (Millwood) 2019 Feb;38(2):190-196

Yue Li is a professor in the Department of Public Health Sciences, University of Rochester.

The Comprehensive Care for Joint Replacement (CJR) model introduced in 2016 aims to improve the quality and costs of care for Medicare beneficiaries undergoing hip and knee replacements. However, there are concerns that the safety-net hospitals that care for the greatest number of vulnerable patients may perform poorly in CJR. In this study we used Medicare's CJR data to evaluate the performance of 792 hospitals mandated to participate in the first year of CJR. Read More

Two-stage management of a spontaneous fracture of the greater trochanter through osteolytic lesions induced by polyethylene wear of a total hip arthroplasty. A case report.

Acta Biomed 2019 Jan 10;90(1-S):177-182. Epub 2019 Jan 10.

Department of Orthopaedic and Trauma Surgery, Integrated University Hospital, Verona.

Pelvic osteolysis induced by particulate debris derived from bearing surfaces is a well-known complication following total hip arthroplasty (THA). Atraumatic fractures of the greater trochanter (GT) associated with osteolytic lesions have been occasionally described. We present a case of a 71-year-old male patient who sustained an undisplaced fracture of the GT nine years following cementless metal-on-polyethylene THA. Read More

Higher blood loss and transfusion requirement in surface arthroplasty versus conventional total hip replacement.

Acta Biomed 2019 Jan 10;90(1-S):87-91. Epub 2019 Jan 10.

Department of Orthopaedic and Trauma Surgery, Integrated University Hospital, Verona.

Background And Aim Of The Work: Surface replacement arthroplasty (SRA) is an alternative to stemmed total hip arthroplasty (THA) providing a femoral bone preserving procedure. Because of the wider surgical dissection, an increased blood loss could be expected. This retrospective study evaluates the transfusion requirement in two homogeneous groups of patients who underwent primary hip replacement electively. Read More

Editorial Commentary: The Child of 2 Mothers: Hip Preservation and Hip Arthroplasty.

Arthroscopy 2019 Feb;35(2):644-645

Chicago, Illinois.

Two orthopaedic disciplines see the same hip joint from a different angle. The arthroplasty specialist corrects the hip joint osteoarthritis by replacing the hip, while the arthroscopy specialist preserves the joint by correcting the mechanical aberrations. Although both of these approaches are well documented in the literature, some patients who undergo hip preservation surgery will have a subsequent hip replacement. Read More

Editorial Commentary: The Hip-Spine Connection in Patients Undergoing Hip Arthroscopy: Should We Learn From Total Hip Replacement and Counsel Patients Differently If They Have Had Previous Back Surgery?

Arthroscopy 2019 Feb;35(2):451-452

St. Louis, Missouri.

Disorders of the adult hip and spine are common, and there is evidence that there is a hip-spine connection in patients with hip femoroacetabular impingement (FAI). Many reports have shown that patients undergoing lumbar fusion and subsequent total hip arthroplasty have a higher risk of complications and worse outcomes following total hip arthroplasty. However, there has been a paucity of research on the effect of a history of lumbar spine surgery in patients undergoing hip arthroscopy for the treatment of FAI. Read More
