PURPOSE: Wide excisions of the extensor tendons at the level of the proximal phalanx (P1) may be required during oncologic resections. We present an original, single-stage reconstructive technique of the extensor apparatus of the hand used after wide resection for Lipofibromatosis (LPF), a rare pediatric soft tissue tumor. METHODS: A 9-year-old girl presented to our institution with a mass on the dorsum of the left hand at the Metacarpophalangeal (MCP) joint of the third digit: following biopsy, the lesion was diagnosed as LPF. Wide surgical excision was performed, requiring complete resection of the extensor apparatus, including the central slip and lateral bands. Reconstruction was performed using a hemisection of the Extensor Digitorum Communis(EDC) tendon to reconstruct the central slip, combined with a Palmaris Longus (PL) autograft to reconstruct the sagittal and lateral bands sutured to the intrinsic muscles. RESULTS: At 2-year follow-up, the patient demonstrated near-complete active extension, full flexion, and no evidence of recurrence. A residual extension lag of 10° at the Proximal Interphalangeal (PIP) joint was observed. Grip strength was comparable to the contralateral side. CONCLUSION: This technique allows functional restoration of the extensor mechanism in a single stage and may represent an alternative in complex reconstructions. The good clinical outcome prompted us to report this technique, which, to our knowledge, has not been previously described. At a current follow-up of two years, the result remains stable, with no evidence of local recurrence.
