The Role Of Nerves In Skeletal Development, Adaptation, And Aging., Ryan E Tomlinson, Blaine A Christiansen, Adrienne A Giannone, Damian C Genetos

Department of Orthopaedic Surgery Faculty Papers

The skeleton is well-innervated, but only recently have the functions of this complex network in bone started to become known. Although our knowledge of skeletal sensory and sympathetic innervation is incomplete, including the specific locations and subtypes of nerves in bone, we are now able to reconcile early studies utilizing denervation models with recent work dissecting the molecular signaling between bone and nerve. In total, sensory innervation functions in bone much as it does elsewhere in the body-to sense and respond to stimuli, including mechanical loading. Similarly, sympathetic nerves regulate autonomic functions related to bone, including homeostatic remodeling and vascular …

Effectiveness Of Home-Based Rehabilitation Program In Minimizing Disability And Secondary Falls After A Hip Fracture: Protocol For A Randomized Controlled Trial, Anum Sadruddin Pidani, Saniya Sabzwari, Khabir Ahmad, Ata Khan, Shahryar Noordin

Department of Surgery Docs

Introduction: Hip fractures are a major health problem globally and are associated with increased morbidity, mortality, and substantial economic costs. Successful operative treatment of hip fracture patients is necessary for the optimization of post-op mobility and functional recovery of the patient. Rehabilitation after surgical stabilization of a hip fracture is crucial in order to restore pre-fracture function and to avoid long-term institutionalization. In particular ongoing exercise which targets balance can prevent up to 40% of falls. Therefore, we have designed a post-discharge home-based physical rehabilitation intervention program to minimize disability and falls in this high-risk elderly population.
Methods and analysis: …

Medial Femoral Condyle Vascularized Bone Graft For Treatment Of Midshaft Clavicle Recalcitrant Nonunion With Use Of The Transverse Cervical Artery As An Anastomosis., Christopher M Belyea, Jefferson L Lansford, Joseph B Golden, Emily H Shin, Rey D L Gumboc

Articles, Abstracts, and Reports

Vascularized medial femoral condyle bone grafts have been reported to be a reliable treatment for recalcitrant bony nonunions of the extremities. Although clavicle fracture nonunions are rare after treatment with open reduction internal fixation, symptomatic nonunions can be a challenge. The medial femoral condyle vascularized bone graft has been described as a treatment option for clavicle nonunions with the thoracoacromial trunk as the recipient anastomosis site. This case illustrates how the transverse cervical artery and accompanying veins can be used as an anastomosis when the thoracoacromial trunk is inaccessible because of previous surgical- and infection-related scaring. At the final follow-up, …


Bilateral Posterior Fracture-Dislocation Of The Proximal Humerus After First-Time Seizure, John D. Murphy, Phillip Braunlich, Mohit Bansal May 2020

Bilateral Posterior Fracture-Dislocation Of The Proximal Humerus After First-Time Seizure, John D. Murphy, Phillip Braunlich, Mohit Bansal

West Florida Division GME Research Day 2020

Fractures of the proximal humerus are commonly associated with osteoporosis and comprise 5.7% of all adult fractures [1]. Posterior dislocations of the shoulder comprise 2-5% of all shoulder dislocations, and when bilateral are even more infrequent, occurring less than 5%. [2,3]. Posterior dislocations are often associated with motor vehicle accidents, seizures, or electrical shock [4]. Fracture-dislocations of the proximal humerus occur in only 1% of all shoulder dislocations, thus making posterior fracture-dislocations off the proximal humerus exceedingly rare [5]. In this case report, we present a previously undescribed case presentation and treatment for bilateral posterior fracture-dislocations of the proximal humerus …
