Summary
Distal radius fractures can lead to malunion, often treated with osteotomy. Careful patient selection and surgical technique are crucial for successful outcomes in managing these common wrist injuries.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand and Wrist Surgery
Background:
- Distal radius fractures are frequent injuries with generally good outcomes.
- A subset of these fractures may develop symptomatic malunion, necessitating corrective surgery.
- Traditional treatment for malunion involves distal radius osteotomy.
Purpose of the Study:
- To review the management of symptomatic malunion of distal radius fractures.
- To emphasize the importance of anatomical and biomechanical understanding for surgical planning.
- To outline key considerations for patient selection and surgical technique.
Main Methods:
- Review of current literature and surgical principles for distal radius malunion.
- Discussion of indications and contraindications for osteotomy.
- Analysis of technical variables including osteotomy type, bone grafting, and fixation.
Main Results:
- Appropriate surgical or nonsurgical management yields acceptable results for most distal radius fractures.
- Symptomatic malunion requires careful consideration of treatment options.
- Successful osteotomy depends on precise surgical technique and patient selection.
Conclusions:
- Understanding anatomy and biomechanics is vital for selecting patients for distal radius osteotomy.
- Treatment planning must address osteotomy type, bone graft use, and fixation.
- Adjunctive procedures and alternative salvage options like wrist fusion may be necessary.

01:09Bones 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.

01:15Bones 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...
01:19Bones 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...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
