Wrist Fractures Management With Arthroscopic Assistance Under Walant - Exploratory Study

Wrist Fractures Management With Arthroscopic Assistance Under Walant - Exploratory Study

Wrist articular fractures are more difficult to treat and rehabilitation takes longer. Furthermore, these joint fractures are frequently accompanied by ligament lesions of the carpal bones.

For these reasons, it is strongly recommended to check the interior of the wrist joint. This check can be done with wrist arthroscopy. Therefore, fracture reduction can be improved, "step of stairs" can be eliminated under arthroscopic control and ligament rupture of carpal bones can be treated.

WALANT anesthesia (Wide Awake Local Anesthesia No Tourniquet) designates a new local anesthesia technique. This technique which allows to maintain the arm or fingers mobility offers several significant advantages:

• Greater precision of the surgical procedure.
• A reduction in discomfort, risks and related adverse effects to anesthesia.
• Faster recovery.

WALANT technique is very comfortable for patient and fits perfectly with principles of Enhanced Recovery in Surgery.

In this context, this study is based on the hypothesis that it is possible to combine arthroscopy and the WALANT anesthesia technique for reducing wrist fractures

Wrist fractures are common. Most often, when speaking about wrist fracture, this means distal radius fracture, the radius being one of the two forearm bones and most often affected in cases of fracture. A fracture is articular when the fracture line "goes down" in the joint.

These fractures are more difficult to treat and rehabilitation takes longer because it is necessary to ensure that joint surface is perfectly reduced, this means that there are no "stair steps" in the joint. Furthermore, these joint fractures are frequently accompanied by ligament lesions of the carpal bones.

For all these reasons, it is strongly recommended to check the interior of the wrist joint. This check can be done with wrist arthroscopy. Arthroscopy not only allows for a complete assessment of lesions but also to treat most of them. Therefore, fracture reduction can be improved, "step of stairs" can be eliminated under arthroscopic control and a ligament rupture of carpal bones can be treated.

WALANT anesthesia (Wide Awake Local Anesthesia No Tourniquet) designates a new local anesthesia technique which is based on administration, in association with local anesthetic (lidocaine), of a medicine (epinephrine) which limits bleeding and allows to dispense with a tourniquet. The local anesthetic administration allows to maintain the arm or fingers mobility, while having complete anesthesia. This technique offers several significant advantages:

• Greater precision of the surgical procedure. In fact, bleeding limitation and the patient's state of cooperation allow a greater surgical precision.
• A reduction in discomfort, risks and related adverse effects to anesthesia.
• Faster recovery.

WALANT technique is very comfortable for patient and fits perfectly with principles of Enhanced Recovery in Surgery. Several studies have shown that it is possible to reduce distal radius fractures under WALANT anesthesia. As for wrist arthroscopy, this is a classic technique for controlling inside of the wrist joint, allowing not only to have an overall view of wrist injuries but also to treat most of them.

In this context, this study is based on the hypothesis that it is possible to combine arthroscopy and the WALANT anesthesia technique for reducing wrist fractures
