Summary
Surgical fixation of adolescent bony mallet fractures is effective for injuries with joint subluxation or significant articular involvement. Timely treatment and patient compliance are key to minimizing complications like infection or extensor lag.
Area of Science:
- Orthopedic surgery
- Pediatric orthopedics
- Hand surgery
Background:
- Surgical intervention is often recommended for adult mallet fractures involving distal interphalangeal (DIP) joint subluxation or >1/3 articular surface.
- Efficacy and complication rates of operative treatment in adolescents remain unclear.
Purpose of the Study:
- To evaluate clinical outcomes of operative fixation for bony mallet fractures in the adolescent population.
Main Methods:
- Retrospective review of 17 adolescent patients surgically treated for bony mallet fractures.
- Techniques included closed reduction with extension block pinning or open reduction with pin fixation.
- Average patient age was 15.2 years; 9 patients had DIP joint subluxation.
Main Results:
- Average pin removal at 28 days post-surgery.
- Low complication rate (11.8%) with major issues in two patients (re-fracture, loss of fixation).
- Delayed treatment (>32 days) was associated with complications like extensor lag.
Conclusions:
- Operative treatment is effective for adolescent mallet fractures with subluxation or significant articular involvement.
- Pin removal at 4 weeks is generally adequate.
- Delayed presentation and non-compliance increase complication risk.

01:18Cognitive Development During Adolescence
654
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

02:24Predicting Reaction Outcomes
11.0K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

01:27Fractures: Bone Repair
5.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

1.3K
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...

The concept of real numbers includes all the values that can be represented on a continuous number line. The system began with basic counting values used for enumeration. It later expanded to include values that represent the absence of quantity and opposites of the counting values. When situations required expressing parts of a whole or dividing quantities evenly, values capable of representing such proportions were developed. When written using decimal notation, these values can end or repeat...
