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...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
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

The syndactylized free lateral arm flap is a viable option for reconstructing extensive finger soft-tissue defects, offering good functional and sensory outcomes. Careful patient selection is key for successful outcomes in complex finger reconstructions.

Area of Science:

  • Plastic Surgery
  • Orthopedic Surgery
  • Microsurgery

Background:

  • Extensive soft-tissue defects in multiple fingers pose significant reconstructive challenges.
  • Traditional methods may have limitations in restoring both form and function.

Purpose of the Study:

  • To evaluate the clinical and functional outcomes of using a syndactylized free lateral arm flap for multiple finger reconstructions.
  • To assess the viability and effectiveness of this reconstructive technique.

Main Methods:

  • Retrospective review of patients (2013-2024) who underwent syndactylized free lateral arm flap reconstruction.
  • Assessment of finger joint range of motion (goniometry), sensory recovery (2PD, SWM), and functional outcomes (QuickDASH).

Main Results:

  • Fifteen patients with 37 reconstructed fingers showed successful flap survival in most cases (1/15 lost).
  • Patients achieved protective sensation and preserved elbow range of motion.
  • Mean QuickDASH score was 31.2, indicating moderate functional impact.

Conclusions:

  • The syndactylized free lateral arm flap is a successful option for extensive finger soft-tissue defects.
  • This flap offers thin, pliable tissue and reliable vascularity.
  • Patient selection and compliance are crucial for optimizing outcomes compared to amputation.
