Wrist joints let your hand move up and down, like when you wave. They also allow bending of the wrist forward or backwards; side-to-side rotation (or sometimes called “corkscrewing”) around a central hinge point on one arm of two separate axes which meet at an angle near where they join together again – this is known as ‘medial epicondylosis'(a medical condition).
Wrist bone structure is made up many smaller bones and joints that allow the hand to move in several directions. It also includes end-of arm bone structures
Carpal bones in the wrist
One of the most complicated joints in your body, the wrist is a busy place where eight small bones join two long ones. The carpal (or carpus) bones make up this complex formation and give it strength while also lending flexibility to move around with ease!
The eight carpal bones are:
- Lunate: a crescent-shaped bone beside the scaphoid
- Scaphoid: long boat-shaped bone under your thumb
- Trapezium: a rounded-square shaped bone above the scaphoid and under the thumb
- Trapezoid: bone beside the trapezium that’s shaped like a wedge
- Capitate: an oval or head-shaped bone in the middle of the wrist
- Hamate: bone under the pinky finger side of the hand
- Triquetrum: pyramid-shaped bone under the hamate
- Pisiform: a small, round bone that sits on top of the triquetrum
The radiocarpal joint is where the radius — a thicker forearm bone — connects with lower wrist bones. The scaphoid, lunate and triquetrum are most often found on your thumb side of this connection point for many people’s wrists which makes it easier if you have an accident here since these three tend to get crushed first before anything else happens at all other places along our arm!
The ulnocarpal joint is the pinky finger side of your wrist. This delicate, yet important connection between three bones — two on each arm—plays a crucial role in everyday tasks like gripping with precision or waving goodbye!
Distal radioulnar joint
The distal radioulnar joint connects the bottom ends of your radius and ulna, without including any wrist bones.
The hand bones connected to the wrist joints
The hand bones between your fingers and wrist are made up of five long, skinny pieces called metacarpals. They make up most of what you would call the “bony” part in backside-of hands!
The bones of your hand connect to the top four wrist joints. The movement you do with them is what makes all those muscles in our body contract or relax at different times, which then causes us to move around as a human being!
When the bones of your hands connect at their base, this is called a carpometacarpal joint.
Soft tissue in the wrist
The major soft tissues in the wrist include ligaments, tendons and bursae. These connective tissues keep your bones together by holding them to each other as well as surrounding fluid filled sacs that reduce friction between these various structures at different points throughout our body’s operating range
Common wrist injuries
The wrists are a complex joint that can be injured or damaged in many ways. Example,
Wrists are one of the most common places for a sprain. A ligament can be damaged when you do too much stretching or carry something heavy, leading to pain and swelling in that area which is graded on how bad it looks:
A mild sprain will have redness but no bruising at all; an intense strain has some blue discoloration as well along with tightness/stiffness while having almost bulbous shapes under skin—the more severe they become before healing over time so don’t step away from work just yet! The best way I’ve found…is prevention through strengthening your wrist muscles prior by doing activities suchs swimming stroke practice.
Also known as ulnocarpal abutment, this wrist condition happens when the length of your arm bones are slightly greater than their radius counterparts. This makes it so that there is not enough space for them to move freely in order maintain stability at joint areas between different parts on our bodies- like how one might break down oradiately through activities such as typing without having pain!
Wrist joint pain is a common side effect for those suffering from arthritis. This can happen due to normal wear and tear or an injury that damages the wrist as well as causing rheumatoid disease, which affects your immune system’s ability to fight off infection at times when it should be doing so most effectively!
The most common kind of wrist fracture is a distal radius break. This occurs when you try catching yourself after falling and fractures the bone at its base, resulting in difficultly moving fingers on that side for some time afterwards as well as pain upon extension towards our palm Side effects may also include swelling near site where injury occurred so treatment will depend greatly upon how bad it gets!
Repetitive stress injuries
They can cause numbness, swelling and pain in the wrist. Stress injuries affect bones ligaments or nerves of your hands from repetitive stress like typing too much at work for instance! They range from carpal tunnel syndrome- which is actually an issue with one’s hand muscles as they become inflamed due to overuse; ganglion cysts where pressure builds up inside a sac filled w/fluid under certain circumstances leading to surgery being needed…depending on what part you’re experiencing there may also be tendinitis involved so treatment will differ depending upon those symptoms present
There are many different conditions that can affect the wrists, so it’s important to talk with your healthcare provider if you notice any changes in them. For example carpal tunnel syndrome has its own exercises and devices which may help relieve some symptoms of pain or discomfort when performing tasks such as writing emails on an office computer keyboard for hours at a time every day
