What are the peripheral nerves of the upper limb?
The five spinal nerves of the upper limb (C5, C6, C7, C8, and T1) are rearranged in a plexus (a kind of interchange area) to form three main nerves, the median, ulnar, and radial nerves.
What are the five major peripheral nerves of the upper limb?

What is upper limb orthosis?
Upper limb orthoses are externally applied devices that help restore or improve function and fix structural characteristics of the nervous and musculoskeletal systems.
Which style of orthosis is best to adequately support the upper extremity when someone is recovering from a median nerve palsy?
If patients do suffer from median nerve palsy, occupational therapy or wearing a splint can help reduce the pain and further damage. Wearing a dynamic splint, which pulls the thumb into opposition, will help prevent an excess in deformity.

What are the 5 major nerve Innervations of shoulder arm?
The fifth and final level of the brachial plexus are the five nerves that feed the shoulder and arm called “branches.” These five branches are named the musculocutaneous, axillary, radial, median, and ulnar nerves.
Is the Suprascapular nerve a peripheral nerve?
The suprascapular nerve is a peripheral nerve of the shoulder and arm. It arises from the upper portion of the brachial plexus, which is a network of nerves that stretches across your check from your neck down to your armpit.

How to manufacture upper limb orthoses?
Manufacturing Guidelines Upper limb orthoses Mould the thermoplastic: • The radial part of the pattern wraps around the thumb and goes through the first web space to be welded to the dorsal side of the splint. • The ulnar part wraps around the hypothenar eminence. • Flare the proximal edge at the wrist.
Where is the proximal edge of the orthosis?
AThe proximal edge starts 2 cm below the axilla and rises over the external face of the arm. BAt the elbow, the cut of the upper part of the orthosis leaves the olecranon and epicondyles free and ends at the centres of the elbow joints.
