In peripheral nerve injury, end-to-side neurorrhaphy has been reported as an alternative in cases that the proximal nerve stump is not accessible. Several hypotheses have been proposed to explain peripheral nerve regeneration after end-to-side neurorrhaphy. Recent evidence suggests that nerve regeneration occurs by collateral sprouting. ⋯ The goal of this technique is to provide satisfactory functional recovery for the recipient nerve, without any deterioration of the donor nerve function. End-to-side technique has been investigated in detail in both experimental and clinical studies. Only a limited number of reported cases in clinical practice, until today, can reveal that end-to-side technique may become a viable means of repairing peripheral nerves in certain clinical situations.

The pain remaining after a needle stick is categorized as neuropathic pain. CRPS (Complex Regional Pain Syndrome) is a typical disease in this category. Neuropathic pain is extremely intractable when it becomes chronic pain, inducing psychological and physical pain in patients over a long period of time. ⋯ In the stage of chronic pain, it is very important to improve patients' ADL (activity of daily living) and QOL (quality of life). If neuropathic pain is suspected, it is crucial to treat at an early stage. Therefore, it should be emphasized that when pain persists after a needle stick, the patient should immediately consult a pain clinician or an orthopedist.

Nerve injuries in the upper extremity can result in severe disability. In the past three decades, progress in microsurgical techniques and instruments have resulted in improved outcomes for nerve injuries. If the prognosis is reasonably good, nerve repair is usually preferred over tendon or flap transfer procedures. ⋯ These procedures abbreviate the interval during which hand function is severely impaired, so that patients have alternatives to persistent nerve palsy with the need of permanent external splints, and long and costly rehabilitation can be shortened. Sophisticated techniques allow minimal donor site morbidity and leave options open in case function of the reconstructed nerve returns. The present article gives an overview of the most common procedures to restore hand function and sensation in the most important digits and provides help for decision making.

ReviewTreatment of posttraumatic injuries to the nerves in the foot and ankle.
Nerve injuries of the foot and ankle can result in pain, numbness, or loss of motor function. A thorough history and physical examination are required to diagnose the injury correctly and guide treatment. Treatment may involve conservative measures, primary nerve repair or nerve grafting, or resection and relocation of painful neuroma. Potential complications include the development of chronic pain syndromes.
