Kristin S Livingston, Michael P Glotzbecker, Benjamin J Shore
Pediatric acute compartment syndrome (PACS) is a clinical entity that must be carefully differentiated from the adult version (ie, acute compartment syndrome). Healthcare providers must understand the variable etiologies of PACS, of which trauma is the most common but can also include vascular insult, infection, surgical positioning, neonatal phenomena, overexertion, and snake and insect bites. In addition to the unique etiologies of PACS, providers must also recognize the different signs and symptoms of PACS...

Kevin M Neal, Evan Siegall
Management of large, severe, stiff spinal deformities in children can be challenging. Adjunctive treatments used in conjunction with spinal osteotomy, instrumentation, and fusion can improve the ultimate degree of deformity correction. These adjunctive treatments include preoperative halo-gravity traction, intraoperative halo-femoral traction, temporary internal spinal distraction, and anterior spinal release. Each of these techniques has unique indications and individual risks. When the appropriate protocols are followed, these techniques can be safe and efficacious...

Involvement of the musculoskeletal system by primary or metastatic malignant neoplasms mimicking common orthopaedic conditions is well recognized. The diagnosis may be delayed in the absence of radiographic abnormalities. Twenty-five percent of lymphoma cases have skeletal involvement, and they can affect both bone and soft tissue. Lymphoma is sometimes discovered by means of routine histologic examination of tissue collected at the time of orthopaedic surgery. To the best of our knowledge, this is the first report of lymphoma occurring at the site of prior shoulder surgery and mimicking an infection...

As the number of primary total hip arthroplasties increases, so does the burden of revision procedures. The decision to revise well-fixed components in the setting of polyethylene wear and osteolysis is controversial. Modular head and liner exchange offers the advantages of reduced invasiveness, faster recovery, and bone preservation. These advantages come at the expense of higher rates of revision surgery for instability. Using the native locking mechanism for securing the new liner is preferred; however, cementing a liner into a well-fixed acetabular component is a practical alternative...

Robert D Bronstein, Joseph C Schaffer
The knee is one of the most commonly injured joints in the body. A thorough history and physical examination of the knee facilitates accurate diagnosis of ligament injury. Several examination techniques for the knee ligaments that were developed before advanced imaging remain as accurate or more accurate than these newer imaging modalities. Proper use of these examination techniques requires an understanding of the anatomy and pathophysiology of knee ligament injuries. Advanced imaging can be used to augment a history and examination when necessary, but should not replace a thorough history and physical examination...

Optimal postoperative pain control allows for faster recovery, reduced complications, and improved patient satisfaction. Historically, pain management after spine surgery relied heavily on opioid medications. Multimodal regimens were developed to reduce opioid consumption and associated adverse effects. Multimodal approaches used in orthopaedic surgery of the lower extremity, especially joint arthroplasty, have been well described and studies have shown reduced opioid consumption, improved pain and function, and decreased length of stay...

Jonathan Schiller, Steven DeFroda, Travis Blood
Lower extremity avulsion fractures are uncommon in the pediatric population and can be misdiagnosed without proper imaging and/or clinical suspicion for these injuries. The most common locations of avulsion injuries are the ischial tuberosity, anterior superior iliac spine, and anterior inferior iliac spine. Less often, avulsion fractures occur in the tibial tubercle, calcaneus, and greater and lesser trochanters. When treated properly with rest and altered weight bearing, most of these injuries heal without complication...

Historically, athletic hip injuries have garnered little attention; however, these injuries account for approximately 6% of all sports injuries and their prevalence is increasing. At times, the diagnosis and management of hip injuries can be challenging and elusive for the team physician. Hip injuries are seen in high-level athletes who participate in cutting and pivoting sports that require rapid acceleration and deceleration. Described previously as the "sports hip triad," these injuries consist of adductor strains, osteitis pubis, athletic pubalgia, or core muscle injury, often with underlying range-of-motion limitations secondary to femoroacetabular impingement...

Femoral fractures between a total hip arthroplasty prosthesis and total knee arthroplasty prosthesis, also called interprosthetic fractures, are challenging clinical problems. The number of patients who have undergone ipsilateral primary or revision joint arthroplasty procedures in both the hip and the knee continues to rise, and the number of interprosthetic fractures is increasing, as well. The growing body of biomechanical and clinical literature on interprosthetic fractures reflects the increased frequency of and interest in these injuries...

INTRODUCTION: Although femoral neck fractures in young patients are rare and their complications are well-documented, there is a paucity of data on patient-reported outcomes for this population. The purpose of this study was to describe the quality of life and the effect of clinical complications on the outcomes of young patients with femoral neck fractures in a Chinese cohort. METHODS: In this prospective observational cohort study, patients aged 18 to 55 years admitted to one of three participating trauma hospitals in China for treatment of a femoral neck fracture were recruited...

The American Academy of Orthopaedic Surgeons has developed Appropriate Use Criteria (AUC) for anterior cruciate ligament (ACL) injury prevention programs. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The clinical patient scenarios presented in the AUC document ACL Injury Prevention Programs were derived from indications typical of patients who commonly present with ACL injuries in clinical practice as well as from current evidence-based clinical practice guidelines and supporting literature...

BACKGROUND: The ideal method for management of the subscapularis tendon during anatomic total shoulder arthroplasty (TSA) remains controversial. METHODS: In a retrospective cohort study, primary anatomic TSA procedures performed with either a subscapularis peel or a lesser tuberosity osteotomy from 2002 to 2010 were reviewed at a minimum 1-year follow-up. The primary outcome measure was the performance of a normal lift-off test postoperatively. Multivariate logistic regression analysis was performed to determine if other covariates besides surgical technique correlated with an abnormal lift-off test result...

Workers' compensation is an employer-funded insurance program that provides financial and medical benefits for employees injured at work. Because many occupational injuries are musculoskeletal in nature, the orthopaedic surgeon plays an important role in the workers' compensation system. Along with establishing the correct diagnosis and implementing an appropriate treatment plan, the clinician must understand the fundamental components of the workers' compensation system to manage an injured employee. Ultimately, effective claim management requires collaboration among the employer, the employee, the legal representatives, the insurance company, and the orthopaedic surgeon...

BACKGROUND: Open tibial shaft fractures require emergent care. Treatment with intravenous antibiotics and fracture débridement within 6 to 24 hours is recommended. Few studies have examined outcomes when surgical treatment is performed >24 hours after occurrence of the fracture. METHODS: This retrospective study included 227 patients aged ≥18 years with isolated open tibial shaft fractures in whom the time to initial débridement was >24 hours. The statistical analysis was based on time from injury to surgical débridement, Gustilo-Anderson classification, method of fixation, union status, and infection status...

Distal radius fractures are common in elderly patients, and the incidence continues to increase as the population ages. The goal of treatment is to provide a painless extremity with good function. In surgical decision making, special attention should be given to the patient's bone quality and functional activity level. Most of these fractures can be treated nonsurgically, and careful closed reduction should aim for maintenance of anatomic alignment with a focus on protecting fragile soft tissues. Locked plating is typically used for fracture management when surgical fixation is appropriate...

Benjamin G Domb, David E Hartigan, Itay Perets
The role and function of the acetabular labrum have been studied extensively in the past decade. Recent studies have proposed that, in addition to causing pain and mechanical symptoms, labral tears may accelerate arthritis. Labral preservation is believed to be important because of the role the labrum plays in maintaining a healthy joint. Treatment of the acetabular labrum is becoming one of the fastest growing fields in orthopaedics; therefore, the treatment decision-making process must be refined. Currently, three commonly practiced labral treatments are available: repair, débridement, and reconstruction...

INTRODUCTION: The purpose of this study was to evaluate the current literature on the use of functional knee braces after anterior cruciate ligament (ACL) reconstruction with respect to clinical and in vivo biomechanical data. METHODS: A systematic search of both the PubMed and Embase databases was performed to identify all studies that reported clinical and/or in vivo biomechanical results of functional bracing versus nonbracing after ACL reconstruction. Extracted data included study design, surgical reconstruction techniques, postoperative rehabilitation protocols, objective outcomes, and subjective outcomes scores...
