What this trial studies

This monocentric observational study uses a mixed retrospective and prospective design to document phantom limb pain and residual limb pain in children and adolescents who underwent limb amputation during childhood. Data are collected from medical records and age-appropriate standardized questionnaires administered at routine follow-up visits at a specialized pediatric limb anomaly center. The study also measures quality of life and functional autonomy and explores associations with age at amputation and surgical history. Results aim to clarify the prevalence, characteristics, and everyday impact of neuropathic pain in this rare population.

Who should consider this trial

Good fit: Children and adolescents aged 5–18 who had a limb amputation before age 15 for girls or 16 for boys, can complete self-report questionnaires in French, have not had surgery on the amputated limb within the past year, and have parental consent.

Not a fit: Patients who may not benefit include non-French speakers, those with insufficient cognitive ability to complete questionnaires, patients currently receiving chemotherapy, adults, or those who had recent surgery on the amputated limb.

Why it matters

Potential benefit: If successful, the findings could help clinicians identify neuropathic pain earlier and guide prevention and management strategies to improve prosthetic use and quality of life.

How similar studies have performed: While adult studies have documented phantom and residual limb neuropathic pain, pediatric data are limited, so applying validated questionnaires in children is relatively novel but builds on adult evidence.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patients aged between 5 and 18 years (inclusive) (Piaget's concrete operational stage to be able to complete the self-assessment questionnaires)
* Patients who underwent amputation before the age of 15 for girls and 16 for boys (average age of completion of lower limb growth)
* Patients who have not undergone surgery on the amputated limb for at least one year (to avoid bias, as any surgery involving incision can cause temporary neuropathic pain unrelated to the amputation)
* Have obtained the signature of the non-objection form by both parents/legal guardians
* Have obtained the child's consent (verbal consent but recorded)
* Be affiliated with a health insurance plan.

Exclusion Criteria:

* Patients who do not speak French
* Patients whose cognitive abilities are insufficient (as determined by a clinician or reported by parents) to be able to complete self-assessment questionnaires
* Patients undergoing chemotherapy (due to transient neuropathic pain)
* Patients who have received chemotherapy and whose side effects have not yet subsided (on a case-by-case basis depending on the chemotherapy used)
* Patients who have received chemotherapy causing neuropathic pain due to this treatment that has not disappeared.
* Patients placed under protective custody.
