Summary
Advancements in upper extremity prosthetics, including externally powered and hybrid devices, aim to restore function after limb loss. New surgical techniques like targeted muscle reinnervation offer improved control and sensation for amputees.
Area of Science:
- Orthopedics
- Biomedical Engineering
- Rehabilitation Medicine
Background:
- Historical records show continuous innovation in amputation care and prosthetics.
- World Wars accelerated the need for advanced limb loss solutions.
- Upper extremity prosthetics face greater complexity than lower extremity devices due to functional demands.
Purpose of the Study:
- To review the historical evolution of upper extremity prostheses.
- To discuss current technological advancements in prosthetic devices.
- To explore surgical innovations addressing amputee challenges.
Main Methods:
- Historical literature review of amputation and prosthetic development.
- Analysis of technological trends in upper extremity prosthetics.
- Examination of surgical techniques like targeted muscle reinnervation and regenerative peripheral nerve interfaces.
Main Results:
- Prosthetic technology has evolved from passive to externally powered and hybrid devices.
- Despite advancements, amputees still face challenges like pain and phantom limb sensation.
- New surgical interventions show promise in improving prosthetic control and sensation.
Conclusions:
- The field of upper extremity prosthetics is rapidly advancing.
- Targeted muscle reinnervation and regenerative peripheral nerve interfaces offer novel solutions.
- An individualized approach to care is crucial for optimizing outcomes in upper extremity amputees.

RACE - Rapid Amplification of cDNA Ends
7.3K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

Muscles that Move the Arm
4.8K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Absolute and Local Extreme Values
79
The highest and lowest values of a function, relative to a reference axis, are known as extreme values. These include absolute maximum and absolute minimum values, which represent the highest and lowest points the function reaches across its entire domain. Within a restricted portion of the function, the highest and lowest values are referred to as local maximum and local minimum values, respectively.Periodic functions, such as sine and cosine, show extreme values at infinitely many points due...

Arteries of the Upper Limbs
2.4K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Veins of Upper Limbs
4.3K
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
