Background: In this prospective safety study, we investigated if the characteristic cytokine expression during bone regeneration is manipulated by the local application of bone morphogenetic protein-7 (BMP-7) in non-union surgery. Therefore, the levels of insulin like growth factor 1 (IGF-1), platelet-derived growth factor AB (PDGF-AB) and transforming growth factor beta (TGF-β) were compared between patients with the gold standard use of autologous bone graft (ABG) and those with additional application of BMP-7 as part of the diamond concept...

The infraorbital nerve (ION) can easily be damaged by orbital trauma and periorbital surgical manipulations, due to its abutment to the orbital floor. Anatomic variability of the ION and surrounding structures has infrequently been documented. The aim of this study is to give precise anatomical knowledge about the ION with surrounding structures, to avoid iatrogenic injury of the ION during periorbital procedures.Forty orbits of 40 skull subjects (20 males and 20 females) were studied to analyze structures around the ION...

BACKGROUND: There is no established treatment for rigid residual deformity of congenital clubfoot (CCF) after walking age. Soft-tissue procedures, osseous procedures, and external fixation have been performed with unpredictable results. We applied the Ponseti method to patients with this condition in order to improve the outcomes of treatment. METHODS: We retrospectively reviewed the cases of 44 patients (68 feet) with congenital clubfoot whose mean age (and standard deviation) at treatment was 4...

OBJECTIVES: Facial Aesthetics, a major consideration in orthodontic diagnosis and treatment planning, may not be judged correctly and completely by simply analyzing dental occlusion or osseous structures. Despite this importance, there is no index to guarantee availability of treatment or prioritize patients based on their soft tissue treatment needs. Individuals having well-aligned teeth but unaesthetic convex profiles do not get included for treatment as per current malocclusion indices...

Osteoradionecrosis is a known complication following radiation therapy, presenting most commonly in the cervical spine as a delayed consequence of radiation that is often necessary in the management of head and neck cancers. In contrast, osteoradionecrosis has rarely been described in the lumbar spine. Here we describe, to our knowledge, the first reported case of lumbar spine osteoradionecrosis, after adjuvant radiation for a primary spinal cord tumor, leading to progressive degenerative scoliosis which required subsequent operative management...

INTRODUCTION: An ideal cranioplasty material is one which adequately restores calvarial continuity, contour and esthetics, provides adequate cerebral protection, is biocompatible and corrosion resistant, lightweight yet strong, easy to manipulate and possesses long term stability. The 3-D Titanium mesh implant fulfills most of these criteria, and offers certain added advantages, as exemplified in this case series. Four patients with post craniectomy osseous defects of varying sizes and at different locations of the calvarium were studied...

Vascular calcification (VC) is seen ubiquitously in aging blood vessels and prematurely in disease states like renal failure. It is thought to be driven by a number of systemic and local factors that lead to extra-osseous deposition of mineral in the vascular wall and valves as a common endpoint. The response of resident vascular smooth muscle cell to these dystrophic signals appears to be important in this process. Whilst in vivo models allow the observation of global changes in a pro-calcific environment, identifying the specific cells and mechanisms involved has been largely garnered from in vitro experiments, which provide added benefits in terms of reproducibility, cost, and convenience...

Recent publications argue that classic metaphyseal fractures are caused by rickets as opposed to trauma. Previous case reports of accidental traumatic classic metaphyseal fractures have been discounted due to lack of identification of the fracture at the time of the traumatic event, and lack of an evaluation for boney metabolic disorders. We report a case of a 20 day old male with a diagnosis of congenital vertical talus who sustained a classic metaphyseal fracture of the distal tibia during manipulation in preparation for intravenous line placement...

Acute management of complex nasal fractures in the adult nose is still frequently conducted using closed reduction techniques as first-line therapy. Treatment outcomes from closed reduction are often disappointing and secondary surgical corrections are required in a sizeable subset of patients. In response to the shortcomings of closed fracture manipulation, classic rhinoplasty techniques have been introduced to improve anatomic fracture reduction. Although these techniques improve the accuracy of skeletal reduction, they also weaken the nose, leaving it susceptible to the deformational forces of healing...

James R Ross, Eric P Tannenbaum, Jeffrey J Nepple, Bryan T Kelly, Christopher M Larson, Asheesh Bedi
BACKGROUND: Often, anteroposterior (AP) pelvic radiographs are performed with the patient positioned supine. However, this may not represent the functional position of the pelvis and the acetabulum, and so when assessing patients for conditions like femoroacetabular impingement (FAI), it is possible that standing radiographs better incorporate the dynamic influences of periarticular musculature and sagittal balance. However, this thesis remains largely untested. QUESTIONS/PURPOSES: The purpose of this study was to determine the effect of supine and standing pelvic orientation on (1) measurements of acetabular version and common radiographic signs of FAI as assessed on two- and three-dimensional (3-D) imaging; and (2) on terminal hip range of motion (ROM)...

Indications for endoscopic resection of fronto-ethmoidal osteomas have been progressively expanded thanks to optimization of surgical exposure and the development of dedicated instruments. Curved cutting drills are still suboptimal to treat hard osseous neoplasms of the frontal sinus. We present two patients affected by frontal osteoma treated with an endoscopic procedure using an ultrasonic bone curette. The ultrasonic bone curette may be considered an effective tool to reduce soft tissue manipulation, optimize surgical time and accelerate the healing process...

Genioplasty, the alteration of the chin through either osseous manipulation or implant augmentation, is an integral component of aesthetic surgery of the face. When performed with proper preoperative assessment and technical execution, the results can harmonize and restore balance between skeletal, soft tissue, and dental components of the lower face. To this end, proper understanding of the underlying anatomy and the changes associated with movement of the chin, alone or in conjunction with formal orthognathic surgery, is paramount...

REVIEW
Haim Sohmer
Air conduction (AC) is accompanied by displacements of the two cochlear windows, bulk fluid flow between them, a pressure difference across the basilar membrane, leading to a passive traveling wave along the membrane, which activates the cochlear amplifier and enhances the displacements. AC interacts with bone conduction (BC) stimulation, so that it has been assumed that BC stimulation also involves a passive traveling wave. However, several clinical conditions and experimental manipulations provide evidence that a passive traveling wave may not be involved in BC stimulation at low intensities...
