Then you will explore the nerve if the nerve fails to recover within 4-6 months (patient may need tendon transfer). Wrist extension with radial deviation recovers first because the extensor carpi radialis longus and brevis gets innervated first before the extensor carpi ulnaris. This may give you the estimated time which is needed for brachioradialis to get some innervation. measure the distance from the fracture down to brachioradialis ,which is the first muscle to be reinnervated. The extensor indices muscle is the last one to recover. Monitor brachioradialis muscle because it is the first muscle to recover. The result is such that fibrillation is bad and polyphasic is good

Immobilise the fracture ,then splint the wrist and obtain EMG and nerve studies in about 6 weeks. Against gravity it will be 3/5 and this is the way to check extension of wrist with gravity eliminated. When you check for recovery of wrist extension, eliminate gravity to be able to check the 2/5 recovery. If you are not sure ask the patient to hitchhike. The interphalangeal joint extension is the function of the intrinsic muscles supplied by ulnar nerve and bot by radial nerve. Make sure that the patient extend their metacarpophalangeal joint and not their interphalangeal joint. Weakness of wrist extension and finger extension. Patient with radial nerve palsy usually present with weakness of wrist and finger extension. If the open fracture is associated with radial nerve palsy, then you do exploration of the open wound, you explore the radial nerve and you fix the fracture. In open fracture, there is an absolute indication to explore the radial nerve with nerve repair, delayed nerve graft or tendon transfer.

85% patients will show improvement in about 3-4 months and full recovery at 6 months. If the fracture is closed with complete radial nerve palsy, usually the treatment is coaptation splint followed by a functional brace and observation for the return of radial nerve function. In open fractures, there will be high incidence of partial or complete laceration of radial nerve therefore consider the exploration of the nerve. In closed fracture, usually there is a neuropraxia of the radial nerve that will improve with time with open fracture, consider that there is a laceration of the radial nerve ( neurotmesis). The primary radial nerve palsy usually occurs from the injury with an increase incidence with the distal third holstein lewis fracture and in midshaft transverse fracture.

Check for the radial nerve function before and after reduction of fracture, especially check the wrist and finger extension. In Holstein Lewis fracture, which is a spiral fracture of the distal third of the humerus, the neuropraxia of the radial nerve is approximately 22%. Radial nerve palsy is about 8-15% in patients with humeral shaft fractures. The radial nerve enters the anterior compartment of the arm approximately 10 cm proximal to the elbow joint. The radial nerve can be found 4cm proximal to the point of confluence of the triceps aponeurosis and the long and lateral head of the triceps. When there is a fracture, the anatomy becomes distorted because of the fracture, so a different method is reliable. The nerve crosses the posterior aspect of the humerus about 20 cm proximal to the medial epicondyle and about 15cm proximal to the lateral epicondyle. The nerve lies posterior to the deltoid tuberosity. Radial nerve can be identified as it runs through the spiral groove between the heads of triceps.
