Osteoarthritis and Platelet-Rich Plasma

As outlined in this author’s last post, Osteoarthritis (OA) is a condition characterized by incremental joint pain and compromised joint function; an arthritic state, which generally affects individuals over the age of 50 years.1 Left untreated, OA can progress into a severe condition and slowly diminish an individual’s productivity and quality of life.1(1)In the following…

Environmental Pollutants, Sweating, and Detoxification

Sears, Kerr, and Bray (2012) indicated that several elements exist in the environment that provide no known benefit, physiologically. Such elements include arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) (Sears et al., 2012). However, said elements have the capacity to bioaccumulate in the body producing aberrations in multiple regions to include the cardiovascular,…

Tracking Osteoporosis

Osteoporosis is a condition characterized by compromised bone strength and elevated bone turnover, which increases an individual’s risk of fracture (Srivastava et al., 2005). Almost 44 million Americans are estimated to have low bone mass which, in 2001, had a direct national expenditure of 17 billion dollars (Srivastava et al., 2005). As such, methods of…

Open Reduction and Closed Reduction Internal Fixation: Pros and Cons

Malalignment or displacement (terms used to describe abnormal position of fracture fragments) of bones requires interventions, which stabilize and immobilize the tissue for optimal healing (Delforge, 2002). Two prominent methods that enhance bony union while reducing chances of malunion (i.e., healed fracture fragments in a malaligned/imperfect position) include the open reduction internal fixation (ORIF) and…

Medial Collateral Ligaments, and the Healing Process

Understanding the tissue healing process, without medical intervention, serves as a baseline to determine and compare the efficacy of modern-day therapeutic techniques. As a means of appreciating the undisturbed process of tissue healing, the following will examine the research of Frank, Woo, Amiel, Harwood, Gomez, and Akeson (1983) as it relates to medial collateral ligament…

Anterior Cruciate Ligament Reconstruction; The “Ligamentization” Process

Ligament strength is essential to maintaining joint stability, and prevention of injury. Collagen, a structural protein constituting 65%-80% of the dry weight of ligaments and tendons, provides the majority of functional integrity and framework, as seen on the anterior cruciate ligament (ACL) (Marumo, Saito, Yamagishi, & Fujii, 2005). Thus, finding a suitable tissue replacement for…

Connective Tissue; Structure and Function

Tissues of the human body can be classified under 4 major sub-types: epithelial, nervous, muscle, and connective (Delforge, 2002). Connective tissue bind cells, other forms of tissues, and organs in a way, which provides mechanical support, strength, integrity, and form to structures found within the body (Delforge, 2002). Finally, connective tissue is composed of 3…

Bone Healing and Strength Training: Implications and Considerations

Recovery from bone fractures follows a chronological process (i.e., hematoma/inflammation, cellular proliferation, and remodeling)helping one appreciate the cellular, physiological, and immunological events that occur during healing (Delforge, 2002). Knowledge of the healing process is essential, as it helps reveal the time, place, and form of mechanical loading through movement-based interventions; processes, which continue to restore…

Androgen Replacement Therapy

Aging has been associated with many signs and symptoms observed in elderly men. Some of these symptoms include: decreases in work capacity, energy, strength, muscle mass, libido, sexual activity, nocturnal penile tumescence, virility, decreased bone density, increases in abdominal body fat, insulin resistance and atherosclerosis (Vermeulen, 2000). It is possible that some or all of…
