Summary
Ulnocarpal impaction syndrome causes ulnar-sided wrist pain due to ulnar head and lunotriquetral complex abutment. Treatment focuses on reducing load on the lunate through surgical procedures.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Disorders
- Biomechanics
Background:
- Ulnocarpal impaction syndrome is a frequent cause of ulnar-sided wrist pain.
- It results from abutment between the ulnar head and the lunotriquetral complex.
- Pain is exacerbated by forearm loading and rotation.
Purpose of the Study:
- To summarize the etiology, diagnosis, and treatment of ulnocarpal impaction syndrome.
- To highlight the role of imaging in diagnosis.
- To outline surgical management strategies.
Main Methods:
- Review of radiographic findings, including positive ulnar variance and lunate cysts.
- Magnetic Resonance Imaging (MRI) for detecting edema in the ulnoproximal lunate.
- Discussion of surgical interventions.
Main Results:
- Radiographs may show positive ulnar variance and cysts.
- MRI can reveal edema in the ulnoproximal lunate.
- Surgical options aim to decrease load on the lunate.
Conclusions:
- Ulnocarpal impaction syndrome requires accurate diagnosis through clinical and imaging findings.
- Surgical treatment, such as ulnar shortening osteotomy or arthroscopic wafer procedure, is effective in managing symptoms.

01:15Bones of the Upper Limb: Ulna
3.3K
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...

01:09Bones of the Upper Limb: Radius
3.8K
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.

01:19Bones of the Upper Limb: Humerus
5.7K
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...

01:22Spinal Nerves: Plexus I
1.6K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:30Impact
273
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

01:17Muscles of the Forearm that Move the Hand and Fingers
1.7K
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...
