Leprosy is a chronic condition. Even after successful medical cure, skin and nervous lesions may persist and progress. Orthopedic lesions resulting in deformities and leading to disabilities may subsequently develop. These lesions are preventable by physical therapy and surgical interventions.
The frequencies for each grade of disability in the ND group were: grade 0–48%; grade 1–22%; grade 2–29%. In the PD group these frequencies were respectively: 0%, 4% and 96%. In NDs, Grade 2 (maximum) disabilities were associated with involvement of the following nerves: median 38,7%; posterior tibial 35,5%; ulnar 19,4%; radial 3,2%; popliteal 3,2%. In PDs these frequencies were respectively: 28,7%, 30,4%, 32,2%, 0% and 8,7%. The more prevalent grade 2 disabilities included mutilation of the upper limbs (similarly present in NDs and PDs) and of the lower limbs (significantly higher in PDs). Plantar wounds and ulcers were more frequent in NDs. Claw hand was mostly observed in PDs.
Grade 2 disability affected preferentially PDs, possibly reflecting the combined effects of the standard of care and the progressive character of the disease itself. Observed affected nerves are in accordance with those described in the literature. Deformities potentially corrected by simple measures such as wound care were less frequent in PDs. Conversely, deformities requiring a more complex orthopedic approach were more frequent in this same group. Our results suggest that there is room for improvement in the preventive measures and orthopedic surgical procedures in leprosy patients in Guinea-Bissau.
