Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Summary
This summary is machine-generated.

Whole and split flexor carpi ulnaris (FCU) muscle flaps offer predictable coverage for posterior elbow defects. Measurements and anatomical landmarks aid in flap selection for varied arm sizes, optimizing surgical outcomes.

Area of Science:

  • Orthopedic Surgery
  • Reconstructive Surgery
  • Anatomy

Background:

  • Posterior elbow soft-tissue defects pose reconstructive challenges.
  • The flexor carpi ulnaris (FCU) muscle flap is a potential option for coverage.
  • Understanding the flap's coverage patterns is crucial for surgical planning.

Purpose of the Study:

  • To evaluate the coverage patterns of whole and split flexor carpi ulnaris (FCU) pedicle muscle flaps.
  • To assess flap viability for posterior elbow soft-tissue defects.

Main Methods:

  • Utilized 17 fresh-frozen cadaveric upper extremities.
  • Measured coverage widths of whole and split FCU flaps, with and without fascial modification.
  • Assessed predictability of flap width using forearm and elbow dimensions.

Main Results:

  • Whole FCU flaps provided an average of 2.7 cm coverage, expandable to ~4 cm with modifications.
  • The FCU ulnar head provided ~75% of the whole muscle's width.
  • Mid-forearm circumference was the most predictive factor for flap width.

Conclusions:

  • Whole and split FCU pedicle flaps provide predictable coverage for 2- to 4-cm posterior elbow defects.
  • Generated divisors improve flap width prediction accuracy for outlier arm sizes.
  • Olecranon tip and central tendon landmarks aid in pedicle identification.
