Glossary of Medical Terms and Abbreviations

Reference for readers of the TEV (Talipes Equinovarus) dossiers. This glossary provides plain-language definitions of clinical abbreviations and technical terms used throughout the TEV medical, patient, and general dossiers. It is written to be accessible to patient advocates, families, and non-clinical readers — not just medical professionals. Terms appear in the order they are used in the wiki; this is not an exhaustive medical dictionary, but a focused guide to the language of these documents.

A

  • AAA — Note: In most medical contexts, AAA denotes Abdominal Aortic Aneurysm. Within these dossiers, AAA refers to Arthroscopic Ankle Arthrodesis, a minimally invasive surgical procedure to fuse (permanently join) the bones of the ankle joint using a camera-guided scope, rather than a large open incision. Fusion eliminates joint motion but can relieve pain in a severely damaged ankle. StatPearls: Abdominal Aortic Aneurysm defines AAA

  • AAFD — Adult Acquired Flatfoot Deformity. A condition in which the arch of the foot progressively collapses in adulthood, often due to tendon failure. In the TEV context, this can result from overcorrection during childhood clubfoot surgery. AOFAS resource on adult acquired flatfoot deformit

  • ABI — Ankle-Brachial Index. A ratio of blood pressure at the ankle compared to the arm, used to assess circulation in the legs. Normal range is 0.9–1.3; 0.4–0.9 indicates peripheral arterial disease (PAD) of increasing severity; below 0.4 indicates critical limb ischemia (dangerously poor blood flow); above 1.3 suggests calcified (non-compressible) arteries and is considered abnormal. This is a standard screening test before any foot surgery or wound treatment. TASC II/ACC-AHA PAD guidelines ABI thresholds

  • ADSC — Autologous Adipose-Derived Stem Cells. Stem cells harvested from the patient's own fat tissue, processed, and reinjected into wounds or surgical sites to promote healing. "Autologous" means the cells come from the patient's own body, reducing rejection risk. PubMed review on adipose-derived stem cells

Higher ASA scores predict higher surgical complication rates. ASA official classification system page

  • AVN — Avascular Necrosis. Death of bone tissue caused by loss of blood supply. In clubfoot patients, the talus bone is particularly vulnerable — AVN can cause the bone to collapse, leading to flat-top talus deformity and severe arthritis. StatPearls: Avascular Necrosis general reference

  • CAP — Cold Atmospheric Plasma. An emerging wound-healing technology that uses ionized gas at room temperature to disinfect wounds and stimulate tissue repair. As of 2024–2025, Phase II clinical trials are underway; verify current status on ClinicalTrials.gov. PubMed review on cold atmospheric plasma

D

  • DFU — Diabetic Foot Ulcer. A chronic wound on the foot of a person with diabetes. Important in the TEV context because most wound-healing research focuses on DFUs; the patient's wounds are structural (from deformity), not diabetic, so evidence must be carefully translated. StatPearls: Diabetic Foot Ulcer

Timed in seconds. ≤10 seconds = normal mobility; 11–20 seconds = within normal limits for frail elderly or those with mobility limitations; >20 seconds = needs assistance outside the home; ≥30 seconds = prone to falls. Wikipedia TUG test article

V

  • VAS — Visual Analog Scale. A pain rating tool where the patient marks their pain on a 10-cm line (0 = no pain, 10 = worst imaginable pain). Used as a primary outcome measure in surgical studies. A reduction of 1.5–3 points is considered a minimal clinically important difference (MCID), depending on clinical context and baseline pain level. Wikipedia VAS article

  • WIfI — Wound, Ischemia, and foot Infection. A classification system that grades three factors — wound severity (0–3), ischemia (0–3), and infection (0–3) — to predict amputation risk and guide treatment. Recommended over the Wagner system for post-surgical clubfoot patients because it better captures the vascular and infection components. PubMed WIfI classification original paper

Evidence Levels (Oxford CEBM 2011)

The TEV dossiers use the Oxford Centre for Evidence-Based Medicine (OCEBM) 2011 Levels of Evidence to rate the quality of research cited. Here are the levels:

  • Level I — Systematic reviews (with or without meta-analysis) of randomized controlled trials or n-of-1 trials. The strongest evidence; synthesizes results from many studies.

  • Level II — Randomized controlled trials or observational studies with dramatic effects. Strong evidence from a single well-designed study.

  • Level III — Non-randomized controlled cohort/follow-up studies. Studies that compare outcomes between groups but without randomization, making them more susceptible to confounding.

  • Level IV — Case series, case-control studies, or historically controlled studies. Studies without a concurrent comparison group. Useful but subject to bias.

  • Level V — Mechanism-based reasoning. The lowest level of evidence; based on physiological or biological reasoning rather than direct clinical data.

Note: The OCEBM 2011 levels are organized by question type (Treatment/Harm, Diagnosis, Prognosis, etc.) and the levels differ across categories. This table reflects the treatment/harm hierarchy. See the Oxford CEBM Levels of Evidence for the complete framework.
