Wrist fracture – How does it happen?
The mechanism of injury is classic and very specific. In the vast majority of cases, a wrist fracture occurs from a specific injury: falling onto an outstretched hand (FOOSH mechanism). The person, trying to protect their body or face during the fall, extends their hands. The entire body weight is abruptly transferred to the wrist, which bends violently backward, exceeding the tolerance limits of the bone.
The conditions under which it occurs include:
- Sports activities (e.g., football, skiing, snowboarding).
- Simple slips (e.g., on a wet floor or on ice) for older individuals.
- Severe, high-energy trauma: Car accidents, motorcycle accidents, or falls from heights (e.g., from a ladder) cause much more severe (comminuted) injuries, crushing the wrist.
- Osteoporosis: Weakened bones (for example, in postmenopausal women with osteoporosis) are porous and tend to “break” much more easily, even with very low-energy falls (e.g., tripping in the living room at home).
Symptoms of wrist fractures
The symptoms of a broken wrist are usually loud and instantly noticeable.
- Severe, acute pain: The pain is immediate and becomes unbearable with the slightest attempt to move the hand or fingers.
- Edema (Swelling): The wrist swells rapidly, often accompanied by bruising (black-and-blue marks) that spreads toward the fingers or forearm.
- Loss of function: It is difficult to, or completely impossible to, move, lean on, or use the hand and wrist to grip anything.
- Deformity (Displacement): The wrist may visually appear crooked or deformed, taking on the classic “dinner fork deformity,” which indicates that the bone has broken and shifted from its position.
- Neurological Symptoms: If the broken bone presses on a nerve (such as the median nerve), the patient may feel immediate and intense numbness in the fingers (acute carpal tunnel compression).
Diagnosis of fractures
Never attempt to “reduce” a traumatized wrist on your own. The specialized upper limb surgeon, Mr. Polyzois will see you, examine you carefully by checking the blood supply and sensation of your fingers, and will immediately send you for simple X-rays. An X-ray in two views (face/profile) will determine if there is a broken bone, where exactly the fracture is located, and how much it has shifted.
Sometimes, especially in comminuted or intra-articular fractures, further imaging studies may be required:
- Computed Tomography (CT scan): Often with three-dimensional imaging (3D), it allows the physician to have much better detail of the displacement, the fragments, and the “personality” of the fracture, planning the surgery with millimeter precision.
- Magnetic Resonance Imaging (MRI): This may be requested if there is suspicion of a ligament tear (such as the scapholunate ligament) or a triangular fibrocartilage complex (TFCC) tear.
It is critical to remember that ligaments (the soft tissues that hold bones together), tendons, muscles, and nerves can also be injured (cut or trapped) when the wrist is violently broken. These associated injuries may need to be addressed simultaneously with the bone.
Wrist fracture treatment
Not all fractures require surgery. Treatment is strictly individualized and depends on many factors:
- The type of fracture: Whether it is simple/hairline, displaced, unstable, intra-articular, comminuted, or open.
- Patient characteristics: Age, occupation (e.g., a manual laborer or athlete has different demands than a retiree), hobbies, daily activity level, as well as whether it involves the “dominant” (good) hand.
- The patient’s general health (coexisting medical conditions).
- The presence of other injuries on the same limb or body (polytrauma patient).
Conservative (Non-Surgical) Treatment: If the fracture is stable and has not shifted, a cast or a special functional splint can be placed (perhaps after a “closed reduction” is performed under local anesthesia in the emergency department) to realign the bones and support the wrist. This also offers relief from the initial pain. The cast usually remains for 4 to 6 weeks, with regular X-ray follow-ups to ensure that the bones have not slipped (displaced) inside the cast as the swelling subsides.
Surgical Treatment: When fractures are unstable, intra-articular, or cannot maintain their proper position inside a cast, they absolutely require surgical intervention to put the broken bones back into their anatomical position and keep them stable. This procedure is called Open Reduction and Internal Fixation (ORIF).
Wrist Fracture Surgery (Osteosynthesis)
Mr. Polyzois and his specialized team undertake the operation using minimally invasive surgery (MIS) techniques, which are bloodless, painless, and fully respect the tendons and nerves of the area. The operation is quick, lasting about 30-45 minutes, and the surgical incision on the palmar surface of the wrist does not exceed, most of the time, 5 centimeters. A huge advantage is that the surgery can be safely performed under regional anesthesia (only the arm numbs) and without general anesthesia, if the patient wishes (Awake Surgery).
Modern Materials (Titanium Plates and Screws)
Mr. Polyzois uses the most modern, innovative, and reliable osteosynthesis materials worldwide. Typically, an anatomical plate (volar locking plate) and latest-generation titanium screws are used. These materials have a low profile (they do not “catch” on tendons) and “lock” together, creating a rigid construct. They are the most suitable for the type and “personality” of each fracture and can hold and maintain the bones and comminuted pieces in their correct, perfect anatomical position, even in osteoporotic bones.
