Summary
Spare parts surgery in hand reconstruction uses tissue from injured digits to restore function. This technique, particularly for the index finger, aids overall hand function when other digits are also damaged.
Area of Science:
- Hand surgery
- Reconstructive surgery
- Orthopedics
Background:
- An injured index finger can significantly impair hand function.
- In cases of multiple digit injuries, especially with thumb involvement, the index finger's role in overall hand function is crucial.
Purpose of the Study:
- To review the concept of spare parts surgery in hand reconstruction.
- To provide examples of this reconstructive technique.
Main Methods:
- Review of the concept of spare parts surgery.
- Presentation of illustrative case examples.
Main Results:
- Spare parts surgery involves transferring tissue from a compromised digit to reconstruct another.
- This technique offers a solution for complex hand injuries.
Conclusions:
- Spare parts surgery is a key concept in hand reconstruction.
- Successful application requires pattern recognition and in-the-moment planning by the hand surgeon.

01:16Muscles of the Forearm that Move the Hand and Fingers
2.8K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

01:10Ankle Joint
3.3K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:09Bones of the Upper Limb: Radius
10.7K
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.

01:20Anatomy of the Eyeball
11.0K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

01:03IR Frequency Region: Fingerprint Region
2.1K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

01:26Bone Markings
8.6K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
