Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Area of Science:

Orthopedics
Reconstructive Surgery
Amputee Rehabilitation

Background:

The Krukenberg procedure is a surgical technique for upper limb amputees, creating a pincer-like grasp by separating the radius and ulna.
It serves as an alternative to advanced myoelectric prosthetics, particularly in resource-limited environments.
The procedure aims to restore prehension and enhance patient autonomy in daily activities.

Purpose of the Study:

To conduct a scoping review of published literature on the Krukenberg procedure.
To explore patient demographics, indications, surgical techniques, and outcomes associated with the procedure.
To assess the efficacy and viability of the Krukenberg procedure in various patient populations.

Main Methods:

A comprehensive scoping review was performed adhering to PRISMA guidelines.
Searches were conducted across major scientific databases including PubMed, MEDLINE, Scopus, and Web of Science.
Eligible studies included peer-reviewed reports detailing outcomes of the Krukenberg procedure, with data extraction on demographics, surgical methods, and results.

Main Results:

Twenty-two studies published between 1937 and 2024 were included in the review.
Trauma was the predominant indication (83.4%), followed by burns (10.4%) and congenital anomalies (5.5%).
The Bunnell incision was common, with nerve and muscle preservation crucial for function; most patients achieved independence with an average pincer strength of 7 kg, and complications were minimal.

Conclusions:

The Krukenberg procedure significantly enhances functional independence and socio-economic reintegration, especially for bilateral amputees.
It remains a valuable and viable surgical option in resource-limited settings where advanced prosthetics are not accessible.
Success is contingent upon meticulous vascular and neural preservation, alongside prompt rehabilitation, though study heterogeneity limits definitive conclusions.
