Abstract:

Objectives: Internal splinting is defined as early tendon transfer performed during or just after nerve repair follow­ing nerve injury and is a controversial issue. The objec­tives of internal splinting are avoiding the use of long term external splinting, avoiding permanent hand deformities until the injured nerve is reinnervated and supporting sensorial recovery. In this paper we present our clinical cases of internal splinting and discuss the results in terms of indications, timing, advantages, and disadvantages of internal splinting. Materials and Methods: We applied internal splinting in 11 patients, 3 patients with radial nerve injury and 8 patients with ulnar nerve injury. Internal splinting was performed contemporarily with the nerve repair in 5 pa­tients, in 2 weeks following nerve repair in 1 patient and in 4 weeks following nerve repair in 5 patients. Pronator teres was transferred to extensor carpi radialis brevis and flexor carpi radialis was transferred to extensor digitorum communis in radial nerve injuries. Omer\'s superficial Y technique and its modification were used for ulnar nerve injuries. Results: Patients were followed up for at least 1 year with physical examination and electroneuromyelography and recovery of sensorial and motor functions were achieved in all of them. Conclusion: We concluded that internal splinting is use­ful for avoiding external splint usage and preventing the establishment of hand deformity until recovery of the nerve. The contribution of internal splinting to sensorial recovery was noteworthy as stated in the literature but the lack of control group and the small number of our cases was limited to come to a definite conclusion. We did not experience any disadvantage of internal splinting.
