The Influence of Local Bone Density on the Outcome of One Hundred and Fifty Proximal Humeral Fractures Treated with a Locking Plate.
There is biomechanical evidence that bone density predicts the mechanical failure of implants. The aim of this prospective study was to evaluate the influence of local bone mineral density on the rate of mechanical failure after locking plate fixation of proximal humeral fractures. ⋯ Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Anatomic Alignment and Integrity of the Sustentaculum Tali in Intra-Articular Calcaneal Fractures: Is the Sustentaculum Tali Truly Constant?
In an intra-articular calcaneal fracture, the sustentaculum tali is generally thought to remain tightly bound to the talus by the interosseous talocalcaneal ligaments, spring ligament, and deltoid ligament, providing a "constant" fragment that remains anatomically aligned. The extensile lateral approach is commonly used for reduction based on this assumption, but because it provides only limited access to the medial aspect of the calcaneus, indirect fracture reduction is required to restore an anatomic relationship of these fragments to the sustentacular fragment. The purpose of this study was to determine the prevalence and displacement of sustentacular fractures in patients with an intra-articular calcaneal fracture, and thus determine whether the sustentacular fragment can be accurately considered as constant and can be consistently relied on to maintain anatomic alignment. ⋯ Prognostic Level IV.

Multicenter StudyAssessing the Effects of Teriparatide Treatment on Bone Mineral Density, Bone Microarchitecture, and Bone Strength.
To gain insight into how teriparatide affects various bone health parameters, we assessed the effects of teriparatide treatment with use of standard DXA (dual x-ray absorptiometry) technology and two newer technologies, high-resolution MRI (magnetic resonance imaging) and finite element analysis of quantitative CT (computed tomography) scans. ⋯ Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

ReviewACGME Accreditation of Orthopaedic Surgery Subspecialty Fellowship Training Programs.
Orthopaedic surgery training in the United States consists of a five-year-minimum orthopaedic surgery residency program, followed by optional subspecialty fellowship training. There is an increasing trend for trainees to complete at least one fellowship program following residency training, with approximately 90% of current trainees planning to complete a fellowship. The purpose of this investigation was to assess the overall variability of orthopaedic subspecialty fellowships in terms of characteristics, match process, and the tendency to be accredited by the Accreditation Council for Graduate Medical Education. ⋯ Orthopaedic subspecialty fellowship programs are rapidly becoming a perceived necessity as part of orthopaedic surgery training. Fellowships continue to vary in matching system and their accreditation characteristics.
