Cerebral palsy (CP) in upper limb produces functional, aesthetic and hygienic issues, and is not always amenable to surgical procedures. We are reporting a single-center, long follow-up experience with tendon transfer in wrist and forearm CP. The CP cases who had undergone tendon transfer in hand, wrist and forearm in a 14-year period were evaluated for change in motion, function and cosmetic appearance and also assessed by Manual Ability Classification System (MACS), and Dash (Disability of Arm, Shoulder, Hand) scores. Forty-two spastic CP patients with a mean age of 19.81 (10–34 years, SD: 5.36) years with a mean follow-up of 5.5 (2–14) years, entered the study. 24 cases were GMFCS I or II and 18 were III or IV. Supination beyond neutral was seen in 48.5%, and improvement in MACS scores in all the cases. Improved ‘grasp’ and ‘release’ and keyboard use was seen in 50%, 71% and 87% respectively. The satisfaction from appearance and improved function of 83–96% correlated positively with GMFSC, MACS and DASH scores. Noticeable improvement in personal hygienic care was seen in only 52% of cases. Tendon transfer in well-selected spastic upper extremity CP cases results in long-time improved function, and limb appearance – correlating with initial GMFCS and MACS scores.
