Triquetrum is one of the eight carpals (small bones) present in our wrist, and it is known to be the most commonly injured bone in the wrist as well. That’s why we are going to discuss fractures occurring in this bone. Present in the outer wrist, it is a three-sided bone, and along with other carpal bones, it is also located in the two rows between the forearm and hand. If this bone broke severely, fracture stabilization may require the application of Orthopaedic Implants like bone screws and pins. A direct impact that occurred suddenly is the commonest reason for the break-in of this bone. In this post, we will gain more insights into this type of fracture.
Symptoms Associated with Triquetral Fracture
A direct impact to the bone, automobile accident, or falling on an outstretched hand could be the reasons for a break in the triquetrum. When this occurs, the symptoms noticed may include:
- Pain in the wrist on the side of the little finger
- Reduced grip strength of the wrist along with the range of the motion
- Deformity of the hand or the finger may also be noticed
Besides the above-mentioned symptoms, in some cases, triquetral fractures may also result in dislocation of another bone in the wrist. While on the other hand, if a nerve is pressed, numbness or tingling feeling may also be experienced in the fingers.
Causes of Triquetral Fracture
A direct blow on the wrist or falling on an outstretched hand is the common cause of triquetral fractures. Sportspeople are also prone to getting this type of fracture as a result of sports injuries. Those who engage in playing inline skating or football are also at a high risk of developing triquetral fractures along with other bone breaks as well.
Above these injuries, people suffering from osteoporosis are also prone to getting their triquetrum break even with a slight fall.
Diagnosis of Triquetral Fracture
A physical examination of the wrist will be performed by the doctor to correctly diagnose the condition. To feel whether a bone break is there, the doctor will gently press on the wrist. During the physical examination, symptoms like swelling, bruising, tenderness, and deformity will also be noticed.
The next step during the diagnosis will be the X-ray examination of the hand and wrist to see how many and what type of breaks are there. This will help in providing the best treatment to fix the condition. In some cases, X-rays fail to provide a conclusive report, and in such situations, a CT scan will be ordered.
Treatment of Triquetral Fracture
The treatment of the condition will depend upon the diagnosis. If the fracture is mild, no surgery will be required. But severe breaks most often require surgical intervention. In mild cases, closed reduction followed by application of a cast, or a splint may do the job. If surgery is required, trauma implants like metal screws and pins will be used to stabilize the fractured bone fragments in their true position.
