Summary
This study introduces innovative vascularized bone grafting techniques for complex hand reconstructions. These island transfers from the ulna offer versatile solutions for challenging bone defects and nonunions, improving healing outcomes.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Microsurgery
Context:
- Difficult bony reconstructions in hand surgery present significant challenges.
- Existing techniques may have limitations in addressing complex defects and nonunions.
Purpose:
- To present novel techniques for bony reconstruction in hand surgery using compound island transfers of ulnar origin.
- To demonstrate the versatility and efficacy of these vascularized bone grafts for various indications.
Summary:
- The study details compound island transfers from the forearm's lower third with reverse flow vascularization.
- These transplants, based on ulnar bone, can be simple osseous fragments or compound cutaneous-osseous/cutaneous-tendineous-osseous grafts.
- Utilizing retrograde rotation, these grafts address recalcitrant scaphoid nonunion, Kienböck disease, fractured osteochondromas, and severe post-traumatic sequelae.
Impact:
- These one-stage procedures provide vascularized bone for reconstruction, enhancing bone healing.
- The techniques offer broad potential solutions for complex hand bone defects.
- Clinical experience with 49 cases supports the effectiveness of these reconstructive methods.

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: 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...
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.
