Ulnar nerve rupture at wrist

The wrist is the joint connecting the palm and the arm, and plays a very important role in our daily life. When doing physical exercise, many professional athletes will wear a wrist guard on their wrist to protect their wrist and prevent wrist sprains. Therefore, if a wrist injury unfortunately occurs, do not take it lightly and be alert to the possibility of symptoms of ulnar nerve rupture in the wrist.

The ulnar nerve is an important nerve in the forearm and hand. Injury to the nerve can cause partial impairment of the hand's motor function, making recovery difficult. If the ulnar nerve is broken and not repaired in time, the area below the broken end will experience a series of symptoms such as numbness, muscle weakness, and joint movement disorders. The specific symptoms vary depending on the location of the injury. Nerve repair takes time. Generally, the growth rate of nerves is considered to be about one centimeter a day. If the ulnar nerve is broken and not repaired in time, the area below the broken end will experience numbness and dysfunction.

How to treat ulnar nerve injury

The ulnar nerve is on the medial edge of the brachial plexus in the upper arm. The main cause of ulnar nerve injury is trauma. After injury, the sensation of the ulnar side of the fingers and ring finger basically disappears. The diagnosis is mainly based on the trauma and clinical symptoms. The following is an introduction to the detailed standards of this trauma.

The intrinsic hand muscle function is poorly restored after ulnar nerve injury repair, especially for high-position injuries. In addition to repairing the nerve as soon as possible, the ulnar motor and sensory nerves in the wrist have been separated into bundles, and nerve bundle sutures can be used to improve the surgical effect. Late functional reconstruction is mainly to correct the claw hand deformity.

1. Ulnar nerve injury is an extraocular complication after macular hole surgery and can be attributed to the face-down arm-fixed position after surgery. The surgeon performing the operation should advise the patient to minimize the time the elbows are in a fixed position, especially to minimize the stress on the flexed elbows.

2. Depending on the extent of ulnar nerve injury, decompression, release or anastomosis should be performed. To gain length, the ulnar nerve can be moved anterior to the elbow. The effect of ulnar nerve anastomosis is not as good as that of radial nerve and median nerve. Most of the radial nerve is motor fibers, most of the median nerve is sensory fibers, and the sensory and motor fibers in the ulnar nerve are roughly equal. Therefore, when suturing, special attention must be paid to accurate positioning and no rotation. Simply suturing the sensory and motor branches on the distal side of the ulnar nerve has a good effect. Prevention of ulnar nerve injury is to avoid trauma

Ulnar nerve recovery signs

When checked with electromyography, it was found that multi-phase waves were produced.

The early clinical manifestation of ulnar nerve injury is half-function nerve dysfunction of the little finger and ring finger, with a high disability rate. The early symptoms are not obvious and easy to ignore. In severe cases, muscle atrophy and claw shape lead to disability. The early clinical manifestations of hand muscle atrophy and muscle weakness lead to disability. It is necessary to identify the condition in time for treatment. If the correct treatment does not recover for three months, surgery to free the nerve and then treat it again can achieve perfect recovery.
