Summary
Radial plate fixation for distal radius fractures offers effective outcomes. This approach is comparable to dorsal or volar fixation, with careful technique minimizing superficial radial nerve injury risks.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
- Trauma Surgery
Background:
- Radial incision with radial plate fixation historically avoided due to superficial radial nerve (SRN) injury risk.
- Careful surgical technique can prevent SRN injury, minimizing soft tissue damage.
- Comparison of radial fixation outcomes with dorsal and volar plate fixation in literature.
Purpose of the Study:
- To compare subjective and objective functional outcomes of radial plate fixation versus dorsal and volar plate fixation.
- Evaluate the efficacy and safety of the radial approach for distal radius fractures.
Main Methods:
- Retrospective study of 36 patients undergoing radial plate fixation for AO type A or B distal radius fractures.
- Objective measurements: grip strength and 3-digit pinch strength (injured vs. uninjured wrist).
- Subjective assessment: Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire.
Main Results:
- Postoperative grip strength in the injured wrist was 68% of the uninjured wrist; no significant difference in dominant/nondominant wrists.
- 3-digit pinch strength in the injured wrist was 89% of the uninjured wrist, with no significant decrease.
- Mean QuickDASH score was 20.9, indicating moderate functional limitation.
Conclusions:
- Radial plate fixation is an effective treatment for distal radius fractures.
- Outcomes are noninferior to dorsal or volar approaches.
- This technique offers a viable alternative with potentially reduced soft tissue injury.

01:12Radius of Gyration of an Area
2.7K
The second moment of area, also known as the moment of inertia of area, is a crucial factor in understanding an object's resistance against bending deformation, or stiffness. To accurately estimate the second moment of area along any axis, one needs to concentrate all areas associated with that object into a thin strip, which should be placed parallel to that particular axis.

01:09Bones of the Upper Limb: Radius
4.9K
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.

No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

01:19Degree of Curvature and Radius of Curvature
505
The degree of curvature and the radius of curvature are fundamental concepts in determining the sharpness or smoothness of a curve. The degree of curvature is a measure of how steeply a curve bends and can be determined using the chord basis or the arc basis. In the chord basis method, the degree of curvature is defined as the central angle subtended by a chord of 30.48 meters, helping in the calculation of the radius of the curve. The arc basis method defines the degree of...

01:23Radial System Protection

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
