Overview of DNA Repair

33.7K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Base Excision Repair

26.4K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Anatomical Positions

20.1K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology01:20

Anatomical Terminology

27.2K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Summary

Distal biceps tendon anatomic repair restores supination strength lost with anterior repair. This posterior approach reattaches the tendon at its anatomical footprint, improving rotational strength and fixation.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Anatomy

Background:

  • Distal biceps tendon injuries cause pain and loss of supination/flexion strength.
  • Surgical repair improves strength but often fails to restore full supination.
  • Traditional anterior repair shifts the attachment site, reducing the radial tuberosity's cam effect.

Purpose of the Study:

  • To introduce and describe the distal biceps tendon anatomic repair technique.
  • To explain how this posterior approach restores normal biomechanics and improves outcomes.

Main Methods:

  • A posterior surgical approach to the radial tuberosity.
  • Utilizing two separate intramedullary buttons for the short and long biceps heads.
  • Positioning the distal biceps insertion at its anatomic footprint, posterior to the radial protuberance.

Main Results:

  • The anatomic repair restores the natural supination cam effect of the radial tuberosity.
  • Provides superior initial fixation strength, comparable to the native tendon.
  • Aims to overcome the supination deficits seen with anterior repair techniques.

Conclusions:

  • The distal biceps tendon anatomic repair technique reliably restores the tendon's anatomical footprint.
  • This approach offers improved rotational strength and superior initial fixation compared to traditional methods.
  • It addresses the limitations of anterior repairs, potentially leading to better functional recovery.
