Summary
Athletes with accessory navicular syndrome (ANS) show poorer outcomes with conservative treatment compared to non-athletes. Early surgery may be beneficial for athletes experiencing symptomatic ANS.
Area of Science:
- Orthopedics
- Sports Medicine
- Podiatry
Background:
- Symptomatic accessory navicular syndrome (ANS) commonly affects young athletes, with symptoms worsening during physical activity.
- This condition can significantly impair athletic performance.
Purpose of the Study:
- To compare radiologic findings and clinical outcomes of accessory navicular syndrome (ANS) between athletes and non-athletes.
- To evaluate the effectiveness of conservative treatment and surgical intervention in these populations.
Main Methods:
- Retrospective analysis of 79 patients diagnosed with ANS (29 athletes, 50 non-athletes).
- Comparison of clinical features and radiologic findings between athletes and non-athletes.
- Evaluation of outcomes after conservative treatment and modified Kidner operation.
Main Results:
- Athletes had significantly lower improvement rates (6.9%) with conservative treatment compared to non-athletes (34%).
- Athletes presented with higher rates of trauma history, interosseous bone movement, and bone marrow edema.
- Younger age at surgery was noted in the athlete group.
Conclusions:
- Accessory navicular syndrome (ANS) in athletes exhibits distinct radiologic findings and a more refractory clinical course compared to the general population.
- Early surgical intervention should be considered for symptomatic ANS in athletes due to limited success with conservative management.

01:10Ankle Joint
3.5K
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...

2.3K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

01:12General Case of Eccentric Axial Loading
587
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...
