Summary
Rugby jersey injuries can cause rare closed avulsion of both flexor tendons. This case involved a large middle phalanx fracture with flexor digitorum superficialis (FDS) avulsion, prompting a classification update for better management.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Closed avulsion of both flexor tendons is an infrequent injury.
- The rugby jersey injury is a specific mechanism causing digital trauma.
Observation:
- A unique case of closed avulsion of both flexor tendons occurred.
- The injury involved the flexor digitorum superficialis (FDS) tendon and a significant middle phalanx fracture.
Findings:
- This specific injury pattern, FDS avulsion with a large middle phalanx fracture, has been documented only once previously.
- The study proposes an updated classification for flexor tendon avulsion injuries.
Implications:
- The proposed classification modification aims to improve the management of this rare injury pattern.
- This research contributes to a better understanding of complex hand and finger injuries.

2.2K
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...

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
