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...

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Assessment of radial pulse

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:

Summary
This summary is machine-generated.

Complex radial head fractures (3+ fragments) often lead to complications with ORIF. Radial head arthroplasty offers a successful alternative for these challenging fractures, optimizing outcomes with careful surgical technique and early motion.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomedical Engineering

Background:

  • Radial head fractures are common elbow injuries.
  • Complex fractures with three or more fragments present significant treatment challenges.
  • Open Reduction and Internal Fixation (ORIF) is associated with high complication rates for these fractures.

Purpose of the Study:

  • To evaluate the efficacy of radial head arthroplasty for complex, comminuted radial head fractures.
  • To compare outcomes of arthroplasty versus ORIF in specific fracture types.
  • To identify factors optimizing success in radial head arthroplasty.

Main Methods:

  • Review of literature on radial head fracture treatments.
  • Analysis of complication rates associated with ORIF for multi-fragment fractures.
  • Assessment of outcomes reported for radial head arthroplasty in complex cases.

Main Results:

  • ORIF for radial head fractures with 3+ fragments shows high incidence of complications (hardware failure, malunion, nonunion, re-operation).
  • Radial head arthroplasty demonstrates good success in treating complex, comminuted fractures unsuitable for non-operative or ORIF treatment.

Conclusions:

  • Radial head arthroplasty is a viable and successful option for complex comminuted radial head fractures.
  • Optimizing surgical success involves meticulous dissection, nerve protection, appropriate implant selection, managing associated injuries, and early protected motion.
