Bones of the Upper Limb: Humerus

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...

Area of Science:

Biomedical Engineering
Rehabilitation Science
Prosthetics and Orthotics

Background:

Upper limb prosthetics aim to restore function and appearance.
Consumer satisfaction is a critical metric for evaluating prosthetic device success.
Understanding user needs drives innovation in prosthetic design.

Purpose of the Study:

To assess consumer satisfaction with existing upper limb prosthetics.
To identify and prioritize design features for future prosthetic development.

Main Methods:

Anonymous surveys were distributed online and in paper format.
Data collected from 242 participants of all ages with varying levels of upper limb absence.
Information gathered included demographics, prosthesis use, satisfaction levels, and design priorities.

Main Results:

Prosthesis rejection rates varied: 39% for myoelectric hands, 53% for passive hands, and 50% for body-powered hooks.
Satisfied users generally reported positive experiences, while dissatisfied users indicated significant issues.
Reduced prosthesis weight was the top design priority, followed by lower cost for adults.
Specific needs included life-like appearance for passive devices, and improved harness comfort, wrist movement, grip, and strength for body-powered devices.
Electric devices require attention to glove durability, sensory feedback, and dexterity.

Conclusions:

Prosthetic design priorities are influenced by consumer goals, prosthesis type, and user age.
Future prosthetic development should prioritize lightweight and comfortable designs.
Addressing specific user needs across different prosthetic types is essential for improving satisfaction.
