Loss injuries of the hand
Summary
This guide details hand injury reconstruction, covering examination and surgical options from skin grafts to complex flaps and replantation. It aims to improve outcomes for surgeons treating hand trauma.
Area of Science:
- Hand surgery
- Trauma reconstruction
Background:
- Loss injuries of the hand are common and require effective surgical management.
- Outpatient surgeons need practical guidance for treating these complex cases.
Purpose of the Study:
- To systematically describe hand examination and reconstructive options for loss injuries.
- To provide a practical overview for outpatient surgeons to improve treatment outcomes.
Main Methods:
- Review of reconstructive techniques including secondary intention, skin grafts, local, axial, distant, and free flaps.
- Discussion of the principles and challenges of hand replantation.
Main Results:
- Various reconstructive methods are presented, from simple to complex, suitable for different defect types.
- Replantation is highlighted as a complex but potentially optimal solution for select cases.
Conclusions:
- A comprehensive approach to hand loss injuries, encompassing examination and diverse reconstruction techniques, is essential.
- This article serves as a practical guide to aid surgeons in decision-making and enhance patient outcomes.

Burn Injuries
2.4K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Muscles of the Forearm that Move the Hand and Fingers
839
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...

Handwashing II: Pre-procedure and Initial Procedure Steps
890
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

Bones of the Upper Limb: Radius
2.1K
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.
The radius has a nail-shaped head, and a...

Bones of the Upper Limb: Humerus
2.9K
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...

Blood and Nerve Supply to the Bones
10.7K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
