Scott R Nodzo, Sonja Pavlesen, Christopher Ritter, K Keely Boyle
Tranexamic acid (TXA) is an effective agent used for reducing perioperative blood loss and decreasing the potential for postoperative hemarthrosis. We hypothesized that patients who had received intraoperative TXA during total ankle arthroplasty (TAA) would have a reduction in postoperative drain output, thereby resulting in a reduced risk of postoperative hemarthrosis and lower wound complication rates. A retrospective review was conducted on 50 consecutive patients, 25 receiving TXA (TXA-TAA) and 25 not receiving TXA (No TXA-TAA), who underwent an uncemented TAA between September 2011 and December 2015...

David Saper, Akash K Shah, Andrew B Stein, Andrew Jawa
Delayed unions and nonunions of the scaphoid are most often treated by open reduction and internal fixation with bone grafting. We sought to evaluate a large consecutive series of nondisplaced or minimally displaced scaphoid nonunions and delayed unions treated by a compression screw without bone grafting by 2 fellowship trained hand surgeons. A total of 23 patients (19 males, 4 females) were identified who had fractures located at the distal third (2), the waist (18), and the proximal third (3). Of the 23 patients, 19 had a complete follow-up (mean follow-up period, 5...

Deepan N Patel, Neal S ElAttrache, Michael B Banffy
This case shows an atypical presentation of an osteochondritis dissecans (OCD) lesion of the radial head with detachment diagnosed on plain radiographs and magnetic resonance imaging (MRI). OCD lesions are rather uncommon in the elbow joint; however, when present, these lesions are typically seen in throwing athletes or gymnasts who engage in activities involving repetitive trauma to the elbow. Involvement of the radial head is extremely rare, accounting for <5% of all elbow OCD lesions. Conventional radiographs have low sensitivity for detecting OCD lesions and may frequently miss these lesions in the early stages...

The purpose of this study is to determine the relationship of body mass index (BMI), age, smoking status, and other comorbid conditions to the rate and type of complications occurring in the perioperative period following periacetabular osteotomy. A retrospective review was performed on 80 hips to determine demographic information as well as pre- and postoperative pain scores, center-edge angle, Tönnis angle, intraoperative blood loss, and perioperative complications within 90 days of surgery. Patients were placed into high- (>30) and low- (<30) BMI groups to determine any correlation between complications and BMI...

Adam M Wegner, Philip R Wolinsky, Michael A Robbins, Tanya C Garcia, Sukanta Maitra, Derek F Amanatullah
This study is the first biomechanical research of headless compression screws for fixation of vertical shear fractures of the medial malleolus, a promising alternative that potentially offers several advantages for fixation. Vertical shear fractures were simulated by osteotomies in 20 synthetic distal tibiae. Models were randomly assigned to fixation with either 2 parallel cancellous screws or 2 parallel Acutrak 2 headless compression screws (Acumed). Specimens were subjected to offset axial loading to simulate supination-adduction loading and tracked using high-resolution video...

The purpose of this study is to determine the prevalence of potential graft-influencing pathologies of the extensor mechanism of the knee in patients presenting with a primary anterior cruciate ligament (ACL) rupture. We performed a retrospective review of the plain radiographs and magnetic resonance imaging (MRI) of all active-duty patients presenting with a primary ACL rupture at our institution between July 2006 and February 2009. Imaging was reviewed to determine the presence of a multipartite patella, unresolved Osgood-Schlatter's disease, and/or radiographic evidence suggestive of patella tendinopathy...

The injury parameters and patient characteristics that affect function after scapular fracture are poorly defined. We performed a retrospective review of 594 adult patients with a minimum 12-month follow-up after scapular fracture. Functional outcomes were prospectively assessed using the American Shoulder and Elbow Surgeons (ASES) survey in 153 patients after a mean of 62 months of follow-up. The population was 78% male, and 88% had injuries caused by a high-energy event. Only 4.6% had injuries isolated to the scapula...

Fiberglass casts are frequently valved to accommodate swelling following injury or surgery. The use of cast spacers has been recommended to bridge this gap between pressure reduction and cast strength, but no studies have assessed their effect on cast pressure. We applied 30 long-arm fiberglass casts to adult volunteers, divided between a univalve group and a bivalve group. A pediatric blood pressure bladder was applied under the cast to simulate soft tissue swelling. Valved casts were secured using an elastic wrap, 10-mm cast spacer, or 15-mm cast spacer...

A patient's perception of hospital or provider quality can have far-reaching effects, as it can impact reimbursement, patient selection of a surgeon, and healthcare competition. A variety of organizations offer quality designations for orthopedic surgery and its subspecialties. Our goal is to compare total joint arthroplasty (TJA) quality designation methodology across key quality rating organizations. One researcher conducted an initial Google search to determine organizations providing quality designations for hospitals and surgeons providing orthopedic procedures with a focus on TJA...

Vascular injury to the popliteal artery during knee surgery is uncommon, but it has significant consequences not only for the patient but also to the surgeon since it poses the threat of malpractice litigation. The vascular anatomy of the lower extremity is variable especially when it involves both the popliteal artery and its branches. An aberrant vascular course may increase the risk of iatrogenic vascular injury during surgery. Careful preoperative planning with advanced imaging can decrease the risk of a devastating vascular injury...

A 23-year-old male active duty soldier presented with a biceps femoris tendon snapping over the fibular head with flexion of the knee beyond 90°. Surgical release of anomalous anterolateral tibial and lateral fibular insertions provided relief of snapping with no other repair or reconstruction required. The soldier quickly returned to full running and active duty. Snapping biceps femoris tendon is a rare but potential cause of pain and dysfunction in the lateral knee. The possible anatomical variations and the cause of snapping must be considered when determining the operative approaches to this condition...

Current literature regarding complications following total joint arthroplasty have primarily focused on patients with osteoarthritis (OA), with less emphasis on the trends and in-hospital outcomes of rheumatoid arthritis (RA) patients undergoing these procedures. The purpose of this study is to analyze the outcomes and trends of RA patients undergoing total knee arthroplasty (TKA) or total hip arthroplasty (THA) compared to OA patients. Data from the Nationwide Inpatient Sample from 2006 to 2011 was extracted using the International Classification of Diseases, Ninth Revision codes for patients that received a TKA or THA...

An increasing interest focuses on the rates and risk factors for hospital readmission. However, little is known regarding the readmission following total shoulder arthroplasty (TSA). This study aims to determine the rates, risk factors, and reasons for hospital readmission following primary TSA. Patients undergoing TSA (anatomic or reverse) as part of the American College of Surgeons National Surgical Quality Improvement Program in 2011 to 2013 were identified. The rate of unplanned readmission to the hospital within 30 postoperative days was characterized...

Osteoarthritis (OA) of the knee is a top cause of disability among the elderly. Total knee replacement (TKR) has been available as an effective and definite surgical method to treat severe OA of the knee. However, TKR is a significant procedure with potential risk for serious complications and high costs. Alternative lower risk therapies that can delay or obviate TKR are valuable to those who are poor candidates for surgery or wish to avoid TKR as long as possible. Given the chondroprotective effects of hyaluronic acid (HA) injections, they are a safe and effective treatment to improve pain, function, and longevity of the knee...

Inadvertent perioperative hypothermia is a significant problem in patients undergoing either emergency or elective orthopedic surgery, and is associated with increased morbidity and mortality. Though in general the incidence of inadvertent perioperative hypothermia in postoperative recovery rooms has been decreasing over the last 2 decades, it still remains a significant risk in certain specialty practices, such as orthopedic surgery. This review article summarizes the currently available evidence on the incidence, risk factors, and complications of inadvertent perioperative hypothermia...

The traditional technique for patella fracture fixation utilizes prominent hardware. Prominent hardware use, however, results in a high rate of reoperation for symptomatic implant removal. This biomechanical study evaluates the effectiveness of a novel patella fixation technique that minimizes implant prominence. Patellar transverse osteotomies were created in 13 pairs of cadaveric knees. Paired knees were assigned to either standard fixation (SF) using cannulated partially threaded screws and stainless steel wire tension band, or buried fixation (BF) using headless compression screws with a No...

Antegrade reamed intramedullary nailing has the advantages of high fracture union and early weight-bearing, making it the gold standard for fixation of diaphyseal femur fractures. However, knowledge of distal femoral anatomy may mitigate the risk of secondary complications. We present a previously unrecognized complication of antegrade femoral nailing in which a 23-year-old man sustained iatrogenic rupture of the medial patellofemoral ligament (MPFL) caused by the distal interlocking screw of the femoral nail...

The importance of cost control in total knee arthroplasty is increasing in the United States secondary to both changing economic realities of healthcare and the increasing prevalence of joint replacement. Surgeons play a critical role in cost containment and may soon be incentivized to make cost-effective decisions under proposed gainsharing programs. The purpose of this study is to examine the cost-effectiveness of all-polyethylene tibial (APT) components and determine what difference in revision rate would make modular metal-backed tibial (MBT) implants a more cost-effective intervention...
