BACKGROUND chronic proximal hamstring tendinopathies is a disabling activity related condition. Currently, there is no well-accepted or extensively documented non-operative treatment option that provides consistently successful results. PURPOSE to evaluate the efficacy of ultrasound guided platelet-rich plasma injections in treating chronic proximal hamstring tendinopathies. METHODS a total...

BACKGROUND Acetabular dysplasia associated with deformity of the proximal part of the femur can result in hip dysfunction and degenerative arthritis in young adults. The optimal method of surgical correction for these challenging combined deformities remains controversial. METHODS We retrospectively analyzed twenty-four hips in twenty patients who underwent a Bernese periacetabular osteotomy,...

objective(s) quinazolinones are heterocyclic compounds, with biological and pharmacological activities, such as inhibiting some proteins, enzymes and reducing blood lipids. materials and methods following previous results of our group, effects of two new derivatives of quinazolinones 9(3)-quinazolinone-2-propyl-2-phenylethyl (qppe) and 9(3)-quinazolinone-2-ethyl-2-phenylethyl (qepe) on livers, ...

STUDY DESIGN A retrospective study. OBJECTIVE To analyze the long-term proximal junctional change in adolescent idiopathic scoliosis (AIS) following segmental posterior spinal instrumentation and fusion 5 years or more after surgery. SUMMARY OF BACKGROUND DATA No study has concentrated on time-dependent long-term proximal junctional change in AIS following segmental posterior spinal instrum...

OBJECTIVE To assess movement of ulnar segments radiographically, following proximal and midshaft ulnar osteotomy or ostectomy after arthroscopic treatment for dogs diagnosed with medial coronoid disease. METHODS Fragmentation and cartilage wear were treated arthroscopically and the presence of incongruity confirmed. Osteotomies were performed at the mid-point or proximal third of the length o...

BACKGROUND The ability to image the coronary arteries noninvasively would represent an advance in patient care. We have developed a magnetic resonance (MR) angiographic technique that allows the acquisition of complete images of coronary flow within a single breath-hold. By this method, the feasibility of noninvasive MR coronary angiography was evaluated in 25 subjects, including 19 healthy adu...

The purpose of this in vitro biomechanical study is to determine the force attenuation capacity of four different hip protectors (KPH1, KPH2, Safehip, and Safetypants) in falling simulations in elderly subjects (falls to the side). The simulated falling conditions were created by a biomechanical testing system, which consisted of an impact pendulum, surrogate pelvis and femur, and two load cell...

OBJECTIVE To quantitatively evaluate the anterior segment using anterior segment optical coherence tomography (AS-OCT) following Boston keratoprosthesis type 1. METHODS A retrospective study consisted of AS-OCT imaging at a single time point postoperatively in 52 eyes. Main outcomes measures include anatomical and functional anterior chamber depth (ACD), angle (ACA) and peripheral and proxima...

BACKGROUND The authors sought to demonstrate the safety and effectiveness of the multilevel stabilization screw (MLSS) technique in decreasing the incidence of proximal junctional failure in long segmental instrumented fusions for adult degenerative scoliosis. METHODS Institutional review board approval was obtained and all patients with adult spinal deformity who underwent the MLSS technique...
