Summary
Secondary trigger finger from neglected partial flexor tendon rupture is uncommon. Surgical repair led to full motion and pain relief, highlighting the need for early exploration of hand injuries.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Trauma Surgery
Background:
- Secondary trigger finger is a rare condition, often resulting from hand trauma.
- Partial flexor tendon ruptures, particularly in zone 2, can lead to this condition.
- Clinical manifestations and optimal treatment strategies are not widely understood.
Purpose of the Study:
- To describe secondary trigger finger caused by neglected partial flexor tendon rupture.
- To discuss the underlying mechanism and effective treatment approaches.
- To evaluate surgical outcomes and patient recovery.
Main Methods:
- Retrospective review of 6 patients treated for trigger finger due to neglected partial flexor tendon rupture.
- Surgical intervention included exploration, debridement, and tendon repair.
- Functional outcomes assessed using Quick-Disabilities of the Arm, Shoulder, and Hand (DASH) and Visual Analogue Scale (VAS) for pain.
Main Results:
- Four patients had partial flexor digitorum profundus (FDP) rupture, three had partial flexor digitorum superficialis (FDS) rupture; two had combined ruptures.
- All patients achieved full range of motion with no recurrence of triggering.
- Average VAS pain scores decreased from 3.6 to 0.3; average Quick-DASH scores improved from 33.6 to 5.3.
Conclusions:
- Early surgical exploration is recommended for even seemingly simple puncture or laceration wounds in flexor zone 2.
- Prompt diagnosis and treatment of partial flexor tendon ruptures can prevent secondary trigger finger.
- Surgical repair offers favorable outcomes, restoring function and alleviating pain.

137.8K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

2.1K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

2.6K
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...
