Radiofrequency ablation (RFA) has a success rate of 70% to 90% in the treatment of osteoid osteoma (OO). Failures are due to malpositioning of probes or incomplete ablation, possibly related to conventional probes’ small heating diameter (range, .5–.8 cm). Cooled-tip probes have a larger heating distance, ablating up to 3 cm, affecting a larger volume, and(More)
Accurate clinical evaluation of the alignment of the calcaneus relative to the tibia in the coronal plane is essential in the evaluation and treatment of hindfoot pathologic condition. Previously described radiographic views of the foot and ankle do not demonstrate the true coronal alignment of the calcaneus relative to the tibia. Some of these views impose(More)
BACKGROUND In some pediatric ankle and wrist injuries, the clinical picture is suggestive of a fracture despite negative standard radiographs. OBJECTIVE The goal of this prospective study was to determine the effectiveness of high-resolution ultrasound (US) in differentiating radiographically occult fractures from sprains. METHODS During a period of 3(More)
The surgical treatment of flexible pes planovalgus deformities resulting from Stage 2 posterior tibial tendon insufficiency is controversial and many techniques have been proposed. We retrospectively reviewed the results of subtalar arthrodesis combined with spring ligament repair/reefing and flexor digitorum longus (FDL) transfer to the navicular. There(More)
BACKGROUND Closed reduction and percutaneous fixation with Kirschner wires (KWs) is the standard of care of pediatric supra-condylar humerus fractures (SCHFs). Failure modes leading to loss of reduction are not clear and have not been quantified. Multiple factors may weaken the KW-bone interface bonding conditions. To the best of our knowledge, the possible(More)
The Quantec Spinal Imaging System (QSIS) is a raster stereography used to measure three-dimensional trunk images. The Q angle, a coronal plane measurement generated by the Quantec Spinal Imaging System (QSIS), was compared with the Cobb angle in assessment of scoliosis curve magnitude. One hundred forty-nine patients with idiopathic scoliosis were evaluated(More)
BACKGROUND Supracondylar fractures of the humerus in children are very common. However, the literature regarding measurements of normal anatomical relationships of the distal humerus in sagittal plane is sparse. METHOD We reviewed the radiographs of normal elbow joints in 142 children treated in our hospital over 2 years. No history of previous trauma of(More)
BACKGROUND Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for infantile malignant osteopetrosis (IMO), but is associated with a high incidence of adverse outcomes. In this study, we present our experience with HSCT for IMO patients comparing different types of conditioning regimens. METHODS Thirty-eight patients with IMO(More)
