Bennett`s fracture affects the trapeziometacarpal joint, which is at the base of the
thumb, it is part of the anatomical snuffbox and is characterized as an articular
A Bennet`s fracture is caused by high-energy traumas, they are not as frequent, but
they should be suspected when a patient has a trauma in the hand and the base of
the thumb is swollen, with difficulty for movement. Additionally, there is a great
limitation to carry out pinching or gripping activities.
Sometimes these types of fractures are not detected in the emergency room
because the carpal and metacarpal bones overlap on the radiograph, hiding the
small fragments, therefore, this is a good reason for those patients who do not
improve from pain in the hand, to get additional diagnostic aids which must be
performed to allow the evaluation of small bone detail, such as a tomography.
Once the diagnosis has been made, the most important thing in these fractures is
that they must be well treated because they interfere with many activities of the
daily life, since they affect the movements of pinching or gripping of the hands.
The hand surgeon has several treatment options, such as cast management (non-
surgical) or surgery. Each one has its own indications and risks, the most important
thing is when the decision of surgery is made, the best option is offered to the
This is how minimally invasive procedures (wrist arthroscopy) have allowed us not
only to magnify the size of the lesion and achieve a more precise reduction of the
fractured fragment, but at the same time it allows us to evaluate the ligaments
around the fracture, thus guaranteeing a quick recovery, minimal pain after
surgery, very small scars, rapid mobility and prompt return of the patient to their
activities of daily living, without pain or limitations.
