Degenerative Disc Disease I: Introduction01:27

Degenerative Disc Disease I: Introduction

Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution01:00

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...

Summary

Most athletes with low back pain improve without medical intervention. This review outlines a treatment algorithm for athletes, emphasizing diagnosis and rehabilitation for lumbar disorders.

Area of Science:

  • Sports Medicine
  • Orthopedics
  • Physical Therapy

Background:

  • Low back pain affects 1-30% of athletes, with over 90% improving naturally.
  • A structured approach is crucial for diagnosing and managing athletic low back pain.

Purpose of the Study:

  • To outline a treatment algorithm for athletes experiencing low back pain.
  • To emphasize diagnostic correlation and rehabilitative principles for lumbar disorders in athletes.

Main Methods:

  • The algorithm prioritizes ruling out non-spinal causes (neoplasm, infection).
  • It differentiates cauda equina compression from elective conditions.
  • Correlation between history, physical examination, and neurodiagnostic testing is emphasized for conditions like herniated nucleus pulposis and spinal stenosis.

Main Results:

  • Imaging studies play a key role in correlating clinical findings with diagnoses.
  • Athletes over 60 undergoing back surgery have a low probability of returning to their prior activity level.
  • Rehabilitative principles, including core stabilization, are vital for prevention and treatment.

Conclusions:

  • A systematic diagnostic approach is essential for effective low back pain management in athletes.
  • Core stabilization and rehabilitation are critical for preventing and treating lumbar disorders.
  • Prognosis for returning to sport after surgery in older athletes should be carefully considered.
