- Brief Summary
If a person has to have a part of their body amputated, in this case their hand, the patient then lacks information about the missing limb, which in many cases leads to pain that severely restricts their quality of life and participation in everyday life.
This is usually phantom and/or neuroma pain. Phantom pain is usually caused by many different mechanisms and occurs in 80-90% of patients.
Pain caused by terminal neuromas affects 13-32% of amputees and manifests itself as residual limb pain.
A neuroma itself is a benign lump that can develop at the site of the defect after a nerve has been severed (neurectomy).
In some cases the impairment is so severe that prosthetic tolerance, functional independence and quality of life can be severely affected.
Numerous treatment options for these types of pain are far from satisfactory for many patients and remain a major challenge for both the clinician and the person affected.
It is often no longer possible for the patients to pursue a profession or hobby due to the pain as well as due to the pain medication required and its possible side effects.
Surgical intervention can therefore be considered for patients who do not (or no longer) respond to conservative pain treatment.
In recent years, many surgical approaches have been introduced to treat or prevent post-amputee pain.
One of these methods can make it possible to create an authentic feeling of the missing limb and thus reduce or eliminate phantom pain by means of targeted sensory reinnervation (TSR) of the lost body part.
Sensory reinnervation means that a nerve which enables a (sensory) perception associated with a sense is "redirected" to a new area of the body and can therefore fulfil at least part of its task again.
In this case, an authentic feeling of the lost body part.
The aim of this retrospective data-analysis is to evaluate data from patients with hand amputation (planned surgery or caused by accident/infection..) who have undergone TSR surgery to treat or prevent phantom and neuro-pain with regard to different parameters.
