Be careful when cleaning your motorcycle this term. 😫
“I was about to go for a ride today and my chain was pretty nasty, so I put it up on the stands and got out the wd-40 and a rag. I started the bike, put it in gear and let it idle. I sprayed the chain down really well and I put the rag up to it and it got caught and took my hand with it through the rearsprocket. I had to have everything above my last joint amputated on my index, pointer and my ring finger on my right hand. Thankfully I am left handed. It was a stupid mistake on my part and now I will forever pay the price for it.”
Hand fascia is a thin sheath of fibrous tissue enclosing muscles, tendons and neurovascular bundles. An uninterrupted three-dimensional collagen matrix gives a framework for longitudinal structures as well as an attachment to skin. Fascia is characterized by its location, density, fibre direction and fascia’s relationship to other structures. The superficial fascia of the hand continues from the dorsum of the hand to the palmar side of the hand. The superficial fascia of the digits is cylindrical being thicker in the lateral side of the fingers.
The skin that covers the dorsum of the hand is greatly different from the skin that covers the palm. The skin of the dorsum of the hand is thin and pliable. It is attached to the hand's skeleton only by loose areolar tissue, where lymphatics and veins course. This fact explains why edema of the hand is manifested predominantly at the dorsum. In addition, this loose attachment of skin makes the dorsum of the hand more vulnerable to skin avulsion injuries and also permits the creation of local flaps.
The skin of the palmar surface of the hand is unique, with characteristics for special function. The palmar skin is thick and glabrous and not as pliable as the dorsal skin. It is strongly attached to the underlying fascia by numerous vertical fibers. These features enhance skin stability for proper grasping function.
If you or a loved one are experiencing these conditions, go to the emergency room immediately to prevent any further complications. Stay safe and stay healthy everyone! 🤓
