Stress-Induced, Aseptic Osteolysis of the Mid-Tibia in a Revision Hinged Total Knee Arthroplasty Mimicking Infection.

In this report, we present the case of an 80-year-old female with pain located over the tip of her cemented tibial stem in a revision hinge total knee arthroplasty with localized osteolysis that looked suspicious for infection. A thorough workup was negative for infection. We postulate that the osteolysis at the end of her tibial stem was initiated by a modulus of elasticity mismatch at the stem tip, which generated a focal area of increased sagittal bone bending and microparticle generation.

Occlusion of an Aortobifemoral Graft after Revision Total Hip Arthroplasty.

With the aging population, the demand for total hip arthroplasty is rising. Improvements in arthroplasty techniques and design allow for total hip arthroplasty to be increasingly performed in older patients and those with multiple comorbidities. Complications are rare in young and healthy patients; however, there is greater risk in patients with multiple medical comorbidities and those who have had prior revision procedures.

Predicting the need for surgical intervention prior to first encounter for individuals with shoulder complaints: a unique approach.

Background: Increasing demand for musculoskeletal care necessitates efficient scheduling and matching of patients with the appropriate provider. However, up to 47% to 60% of orthopedic visits are made without formal triage. The purpose of this study was to develop a method to identify, prior to the initial office visit, the probability that a patient with shoulder symptoms will need surgery so that he or she can be appropriately matched with an operative or nonoperative provider.

Medical Malpractice in Pediatric Orthopaedics: A Systematic Review of US Case Law.

Background: Compared with other orthopaedic subspecialties, pediatric orthopaedic surgeons are thought to be at greater risk for malpractice claims; however, there is scant research on this topic. The purpose of our study was to characterize publicly available malpractice cases pertaining to pediatric orthopaedics to determine the (1) most common specialties of the physicians implicated, (2) most common diagnoses involved, (3) rate of verdicts in favor of the plaintiff, (4) amount of indemnity payments resulting from all verdicts versus verdicts in which only an orthopaedic surgeon was involved, and (5) outcomes of cases that were appealed.

Methods: The Westlaw legal database was queried for jury verdicts, settlements, and appellate cases using the search terms "pediatric" AND "orthopaedic" from December 31, 1984, to January 1, 2016, yielding 176 appellate court cases and 189 jury reports/settlements.

Effectiveness of surgical and non-surgical management of crouch gait in cerebral palsy: A systematic review.

Background: Cerebral palsy (CP) is a prevalent group of neuromotor disorders caused by early injury to brain regions or pathways that control movement. Patients with CP exhibit a range of functional motor disabilities and pathologic gait patterns. Crouch gait, characterized by increased knee flexion throughout stance, is a common gait pattern in CP that increases energy costs of walking and contributes to ambulatory decline.

Walking Out of the Curve: Thoracolumbar Kyphosis in Achondroplasia.

Background: Thoracolumbar kyphosis (TLK) is common in infants with achondroplasia. Our goals were to examine the natural history of TLK and identify factors associated with persistent TLK.

Methods: We reviewed records of patients with achondroplasia seen by a board-certified orthopaedic surgeon at a tertiary care medical center between 1997 and 2013.
