BACKGROUND Electronic Medical Records (EMRs) are increasingly used in the provision of primary care and have been compiled into databases which can be utilized for surveillance, research and informing practice. The primary purpose of these records is for the provision of individual patient care; validation and examination of underlying limitations is(More)
It is unclear if a decrease in cancellous bone density or cortical bone thickness is related to sacral insufficiency fractures. We hypothesized that reduction in overall bone density leads to local reductions in bone density and cortical thickness in cadaveric sacra that match clinically observed fracture patterns in patients with sacral insufficiency(More)
BACKGROUND The etiology of peritalar subluxation (PTS) is poorly understood and likely mutifactorial. An anatomic predisposition for posterolateral subluxation of the hindfoot has not been previously described or investigated. The aim of the current study was to describe the morphology of the subtalar joint axis (STJA) in patients with symptomatic PTS(More)
Osteochondral lesions of the distal femur represent a challenging clinical entity, particularly in patients > 40 years of age. Microfracture has demonstrated inferior results in this population with clinical deterioration beyond 1 to 2 years postoperatively. Limited evidence exists to support alternative cartilage restoration procedures. The purpose of this(More)
Control of knee motion in small animal models is necessary to study the effect of mechanical load on the healing process. This can be especially challenging in mice, which are being increasingly used for various orthopedic reconstruction models. We explored the feasibility of botulinum toxin (Botox; Allergan, Dublin, Ireland) paralysis and a newly designed(More)
PURPOSE To determine the effect of a knot-tying module, within an arthroscopic training course, on resident speed, resident confidence, and biomechanical quality of arthroscopically tied knots. METHODS Sixty-four participants (8 postgraduate year [PGY]-3 and 8 PGY-4 orthopaedic residents annually for 4 years) were enrolled in a 5-day training course,(More)
It has been suggested that variances in the anatomy of the acetabulum determine the type of hip fracture in elderly patients. Based on this concept, an overly anteverted acetabulum would lead to impingement of the femoral neck against the posterior rim of the acetabulum, causing a femoral neck fracture, whereas with a retroverted acetabulum, external(More)
Background Chondral lesions in the patellofemoral compartment represent a difficult entity to treat among active patients, with no clear consensus on the optimal treatment strategy. The purpose of this study was to review the functional outcomes of patients >40 years old with primary patellofemoral osteochondral lesions who underwent a cartilage restoration(More)
