INTRODUCTION: Our study assessed the effect of total intravenous anesthesia (TIVA) with short-acting spinal anesthesia and aggressive day-of-surgery postoperative day 0 physical therapy (POD#0 PT) on hospital length of stay (LOS) in patients who underwent primary total joint arthroplasty. METHODS: A retrospective chart review compared the hospital LOS of 116 patients who underwent primary total hip arthroplasty and total knee arthroplasty with TIVA and short-acting spinal blockade ("Updated protocol group") with that of the control group of 228 patients who were under standard anesthesia ("Traditional protocol group")...

The design of total ankle arthroplasty systems is evolving as a result of findings from longer-term studies. Our understanding of modes of failure has increased, and surgical techniques have become more refined. Currently, five total ankle arthroplasty systems are used in the United States. The landscape has changed considerably in the decade since the latest article reviewing total ankle design was published. Some implants with acceptable intermediate results had much poorer outcomes at 7- to 10-year follow-up...

Tibial spine fractures are uncommon injuries affecting the insertion of the anterior cruciate ligament on the tibia. They typically occur in skeletally immature patients aged 8 to 14 years and result from hyperextension of the knee with a valgus or rotational force. Diagnosis is based on history, physical examination, and standard radiographs. The use of MRI can identify entrapped soft tissue that may prevent reduction. Open or arthroscopic repair is indicated in patients with partially displaced fractures (>5 mm) with one third to one half of the avulsed fragment elevated, in patients who have undergone unsuccessful nonsurgical reduction and long leg casting or bracing, and in patients with completely displaced fractures...

BACKGROUND: Although diabetes mellitus (DM) has been established as a risk factor for infection after lower extremity arthroplasty, no association has been reported with shoulder arthroplasty. METHODS: We queried a national database for patients with DM who underwent primary shoulder arthroplasty. We identified perioperative hemoglobin A1c (HbA1c) levels and assessed the incidence of wound complications within 6 months and deep infection that required surgical intervention within 1 year for each HbA1c level...

INTRODUCTION: The dangers of radiation exposure in children have been well studied, with assessment of adolescent idiopathic scoliosis (AIS) documented as having the potential for notable patient exposure. The purposes of this study were to evaluate a consecutive series of patients referred to a tertiary care pediatric hospital for AIS and to assess the type and quality of imaging obtained before referral for specialist evaluation. METHODS: We performed a prospective study of consecutive patients referred over a 6-month period to a pediatric orthopaedic practice at a large, free-standing, urban children's hospital for evaluation of AIS...

Recurrent anterior shoulder instability is associated with glenohumeral bone loss. Glenoid deficiency compromises the concavity-compression mechanism. Medial Hill-Sachs lesions can result in an off-track humeral position. Anterior glenoid reconstruction or augmentation prevents recurrence by addressing the pathomechanics. In Bristow and Latarjet procedures, the coracoid process is harvested for conjoint tendon transfer, capsular reinforcement, and glenoid rim restoration. Complications and the nonanatomic nature of the procedure have spurred research on graft sources...

Achieving fracture union is highly dependent on the initial inflammatory phase of fracture healing, which is influenced by both the local and systemic inflammatory environments. The rapidly emerging field of osteoimmunology involves the study of the interactions between the immune system and the skeletal system. Recent research has advanced the current state of knowledge regarding the effects of the surrounding soft-tissue injury, fracture hematoma, and the method of fracture fixation on the inflammatory phase of fracture healing...

Aneurysmal bone cysts (ABCs) are considered to be rare benign tumors that may affect long bones or the vertebral column. Their incidence varies and is reported to be 1.4% of all benign skeletal tumors. The solid-variant aneurysmal bone cyst (S-ABC) is even rarer and constitutes 3.5% to 7% of all vertebral ABCs. We report the case of an Enneking stage 3 S-ABC in a 5-year-old boy at C7 that showed rapid local recurrence after primary excision from posterior and dorsal stabilization requiring ventral corpectomy and posterior excision of the right lateral mass and right posterolateral fusion...

Seth L Sherman, Samuel F Thompson, John C F Clohisy
Distal femoral varus osteotomy is a well-described treatment option for patients with valgus malalignment associated with a variety of underlying conditions. This procedure may be the definitive treatment option in active patients with isolated lateral compartment osteoarthritis or posttraumatic arthritis. It may be a useful concomitant procedure in young patients with lateral meniscus deficiency, focal chondral defects, chronic medial collateral ligament insufficiency, and/or patellofemoral instability. Distal femoral varus osteotomy can be performed with medial closing wedge or lateral opening wedge techniques...

In the past 30 years, the use of ultrasonography in the field of orthopaedics has evolved. As ultrasonography has been refined, smaller machines with higher fidelity and better transducers have become available at a lower cost. Diagnostic and therapeutic applications of ultrasonography in the shoulder and elbow have expanded imaging options and provided alternatives to surgical management. Ultrasonography is a dynamic tool that affords immediate diagnostic assessment for clinical correlation and can be used for serial examinations and image guidance during therapeutic procedures...

Wound complications and surgical site infections after orthopaedic procedures result in substantial morbidity and costs. Traditional postoperative wound care consists of applying sterile, dry gauze and abdominal pads to the surgical site, with more frequent dressing changes performed in cases in which wound drainage is excessive. Persistent incisional drainage is of particular concern because it increases the risk of deep infection. The use of closed incision negative-pressure wound therapy (ciNPWT) to manage delayed wound healing was first reported a decade ago, and the benefits of this treatment modality include wound contraction with diminished tensile forces, stabilization of the wound environment, decreased edema and improved removal of exudate, and increased blood and lymphatic flow...

Vitamin D is known to be important for calcium homeostasis and bone metabolism. It also has important direct effects on skeletal muscle. Unlike authentic vitamins, which cannot be synthesized in the body, vitamin D is produced in the skin using sunlight. Through its nuclear receptor (ie, vitamin D receptor) located throughout the body, including skeletal muscle, vitamin D initiates genomic and nongenomic pathways regulating multiple actions, including myocyte proliferation and growth. In some studies, vitamin D supplementation has been shown to increase muscle strength, particularly in people who are vitamin D deficient...

INTRODUCTION: The relationship of hip range of motion (ROM) to shoulder, elbow, abdominal, and back injuries remains undefined. METHODS: We assessed hip ROM on players reporting to Major League Spring Training for an organization over six seasons (2010 to 2015). Hip ROM was correlated with player abdominal, back, shoulder, and elbow injury status for those seasons using multivariate binomial logistic regression analysis. RESULTS: A total of 258 player-seasons (129 pitchers and 129 position players) resulted in 20 back and 35 abdominal injuries across all players and 28 elbow and 25 shoulder injuries in pitchers...

BACKGROUND: Radiostereometric analysis (RSA) accurately assesses arthroplasty implant performance and is routinely used for research purposes. Because of its efficacy in detecting implant failure in research subjects, we deployed the use of RSA beads for routine surveillance in all elective total hip and total knee arthroplasty patients. METHODS: We retrospectively compared 143 patients who received RSA beads intraoperatively with 343 patients who did not receive RSA beads...

Youichi Yasui, Yoshiharu Shimozono, John G Kennedy
Surgical procedures for managing chronic lateral ankle instability include anatomic direct repair, anatomic reconstruction with an autograft or allograft, and arthroscopic repair. Open direct repair is commonly used for patients with sufficient ligament quality. Reconstruction incorporating either an autograft or an allograft is another promising option in the short term, although the longevity of this procedure remains unclear. Use of an allograft avoids donor site morbidity, but it comes with inherent risks...

Dirk H Alander, Shari Cui
Percutaneous pedicle screw fixation has evolved as a useful tool in the management of spinal trauma. As a minimally invasive approach, it provides the stability of open instrumentation while limiting blood loss, avoiding excessive muscle/soft-tissue insult, and improving postoperative pain and mobilization. Muscle-dilating techniques also preserve greater paraspinal muscle volume and strength compared with open midline approaches. In patients with spinal trauma, the use of percutaneous instrumentation and indirect reduction can theoretically preserve the fracture hematoma and its osteogenic inflammatory factors...

INTRODUCTION: Postdischarge disposition after shoulder replacement lacks uniform guidelines. The goal of this study was to identify complication and readmission rates by discharge disposition and determine whether disposition was an independent risk factor for adverse events, using a statewide database. METHODS: Data from the California Office of Statewide Health Planning and Development discharge database were used. Patient information was assessed, and 30- and 90-day complication rates were identified...
