Standard management typically involves early centralisation to align and stabilise the wrist, followed by pollicisation when the thumb cannot be reconstructed. However, little attention has been paid to pre-pollicisation-rehabilitation strategies that might facilitate the acquisition of postoperative pinch function. This study aimed to report early functional outcomes after staged reconstruction for severe RLD, highlighting a structured pre\u2011pollicisation programme that establishes index\u2013middle finger pinch after wrist centralisation.<\/jats:p>\n                  <jats:p>Methods: We retrospectively reviewed four children (six hands) with RLD treated between 2022 and 2024 with staged reconstruction: (1) early orthotic management, (2) wrist centralisation at approximately 1 year of age and (3) pollicisation of the index finger at 2\u20133 years of age. All patients underwent a structured pre-pollicisation rehabilitation programme focussing on the development of index\u2013middle finger pinch after centralisation. Outcomes at 6\u201318 months after pollicisation included grasp patterns and a tape measure-based pinch test.<\/jats:p>\n                  <jats:p>Results: All hands achieved cylindrical and spherical grasps, and four hands demonstrated early fine motor tasks, such as scissor use and pre-writing. The mean tape measure-pinch score was 3.5 points (range: 1\u20134) on a 5-point scale. One hand showed poorer function, corresponding to marked preoperative hypoplasia of the index donor finger. Wrist alignment and thumb opposition posture were maintained during the short-term follow-up period.<\/jats:p>\n                  <jats:p>Conclusions: Staged centralisation and pollicisation produced encouraging early functional outcomes in children with severe RLD. Pre-pollicisation-training to establish index\u2013middle finger pinch after centralisation appeared to facilitate early acquisition of post-pollicisation-pinch and grasp, and may represent a simple, practical adjunct to standard surgical care.<\/jats:p>\n                  <jats:p>Level of Evidence: Level IV
