In general, reconstruction of the upper limb can only be performed if active elbow extension is present. This stabilizes the elbow and gives the patient a reach. It will also allow the transfer of the other muscles crossing the elbow joint (like the m. brachioradialis and m. extensor carpi radialis longus).
A harvested tendon, such as the palmaris tendon [11] from the forearm of the same or opposite elbow, the patellar tendon, hamstring, toe extensor or a donor's tendon , is then woven in a figure-eight pattern through the holes and anchored. [10] The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11]
Targeted reinnervation has an efferent and an afferent component. Targeted muscle reinnervation is a method by which a spare muscle (the target muscle) of an amputated patient is denervated (its original nerves cut and/or de-activated), then reinnervated with residual nerves of the amputated limb. [1]
If reconstruction of the motor function of the musculocutaneous nerve (elbow flexion) is needed then there are several options, depending on the injury pattern and timeframes. If the nerve is in-continuity and the fascicles appear healthy under the operating microscope then Neurolysis may be sufficient. When there is a division or segment of ...
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
The original technique was first described by Eden [4] in 1924 and verified by Lange in the 1950s. [5] [6] The rhomboid major and rhomboid minor were transferred laterally from the medial border of the scapula to the infraspinatous fossa, and the levator scapulae was transferred laterally to the spine of the scapula, near the acromion.
Nerve allotransplantation (allo- means "other" in Greek) is the transplantation of a nerve to a receiver from a donor of the same species. For example, nerve tissue is transplanted from one person to another. Allotransplantation is a commonly used type of transplantation of which nerve repair is one specific aspect.
