Long-term clinical results of 33 thumb replantations
Research article published in Injury (2020)
Abstract
INTRODUCTION: Thumb replantation following complete amputation is a relatively frequent and well-established surgical procedure. In literature many studies report a discrepancy between the objective measurements and the subjective satisfaction of the patients. Nowadays, evaluation of the patient long-term benefit obtained by replantation is uncertain. The aim of this study was to consider the long-term results of 33 thumb replantation procedures. METHODS: The period considered is from January 1997 to December 2015, 33 subjects fulfilled the study inclusion criteria and were included in the study. We evaluated in each patient: ROM (performing Kapandji test), level and mechanism of amputation, force peak of three grips using Dexter dynamometer (five-handle, key, tri-digital grips), sensibility (using Disk-Criminator and aesthesiometers of Semmes-Weinstein) and subjective perception of disability (using DASH questionnaire). RESULTS: All patients were males, 94% of them returned to their previous occupation. Average follow-up was 9±4 years. The prevalent mechanism of injury was a combined amputation in 58% of cases. Levels involved in more than half of patients were interphalangeal joints and proximal phalanxes. Ratios of strength recovery were: for the five-handle grip equal to 0.90±0.28 kg (p=0.63), 0.78±0.30 kg (p=0.64) for key grip and 0.75±0.32 kg (p=0.78) for tri-digital grip. Results for Kapandji test was 8±2 and for DASH test was 16±21. The protective tactile threshold was recovered in 49% of patients; S2PD test resulted positive in 54% and D2PD test in 39% of cases. CONCLUSIONS: Results confirm and strengthen evidence of positive long-term functional outcomes of thumb replantation interventions.

Summary
Thumb replantation following complete amputation is a relatively frequent and well-established surgical procedure.
Why This Matters for Hirudotherapy
This study evaluated long-term functional outcomes (average 9±4 years follow-up) in 33 male patients who underwent thumb replantation after complete traumatic amputation, assessing range of motion, grip strength, sensibility, and subjective disability (DASH). Results showed that 94% returned to their previous occupation, with good strength recovery ratios and reasonable sensory recovery, supporting the long-term benefit of thumb replantation. The study does not mention or employ leeches, hirudotherapy, or any leech-derived agents. There is no direct relevance to ASH's domain; the connection is limited to the general surgical context of digital replantation, with no leech-related content or findings.
