The Space of Parona is a specific anatomical area located in the distal volar forearm. This space, first described by Francesco Parona (1842–1908) in 1876, is a deep potential space with particular clinical relevance.
Key Features of the Space of Parona
Here's a detailed look at the space:
| Feature | Description |
|---|---|
| Location | Distal volar (palm-side) forearm |
| Boundaries | Extends from the proximal margin of the carpal tunnel to the origin of the flexor digitorum superficialis muscle |
| Nature | A deep potential space, meaning it is not normally an open cavity but can become one when fluid accumulates, such as during an infection. |
| Historical Note | First described by Francesco Parona in 1876. |
Clinical Significance
The Space of Parona is clinically significant because it can be the site of infections, particularly those originating from:
- Deep palmar space infections
- Adjacent tendon sheath infections.
These infections can extend along the space, potentially causing significant complications if not treated promptly. Due to its location and potential for spread, understanding this space is crucial for clinicians in diagnosing and managing hand and wrist infections.
Summary
In summary, the Space of Parona is a deep, potential space in the distal forearm between the carpal tunnel and the flexor digitorum superficialis muscle origin. It's clinically important because it can act as a conduit for the spread of infections.
