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...

Summary

This summary is machine-generated.

Total elbow arthroplasty (TEA) offers pain relief and improved motion for elbow conditions. Unlinked implants require careful patient selection and surgical technique for optimal outcomes, with recent designs offering intraoperative flexibility.

Area of Science:

Orthopedic Surgery
Biomedical Engineering

Background:

Total elbow arthroplasty (TEA) has evolved from treating rheumatoid arthritis in older adults to addressing diverse elbow pathologies in younger, active patients.
Two primary TEA designs exist: linked/semiconstrained implants (mechanically stable) and unlinked implants (relying on soft tissues and bearing architecture for stability).

Purpose of the Study:

To review the current understanding and clinical application of linked versus unlinked total elbow arthroplasty.
To highlight the critical factors for successful outcomes with unlinked TEA, particularly in higher-demand patients.

Main Methods:

Review of existing literature and clinical data comparing linked and unlinked total elbow arthroplasty.
Discussion of implant design principles, stability requirements, and patient selection criteria for unlinked TEA.

Main Results:

Unlinked implants theoretically reduce stress on bone-cement interfaces, potentially decreasing wear and loosening, but have not yet demonstrated superior survivorship over linked devices.
Historically, unlinked implants had higher revision rates due to instability and design flaws; however, recent series show comparable outcomes to linked devices.
Convertible implant designs now allow for intraoperative conversion from unlinked to linked configurations, enhancing surgical adaptability.

Conclusions:

Unlinked TEA provides reliable pain relief and enhanced range of motion for various elbow disorders.
Meticulous preoperative assessment of elbow stability and precise surgical technique are paramount for successful unlinked TEA.
The development of convertible implants offers improved intraoperative decision-making regarding elbow stability.
