[Percutaneous treatment of unstable fractures of the base of the middle phalanx : Technique according to Hintringer and Ender].

OBJECTIVE: Reconstruction of intra-articular impression fractures of the middle phalanx by percutaneous reduction over a small dorsal cortical window. Stabilization by lattice-like arranged K‑wires. INDICATIONS: Impression fractures of the base of the middle phalanx with or without dislocation in the proximal interphalangeal joint. CONTRAINDICATIONS: Fractures extending to the shaft of the middle phalanx. SURGICAL TECHNIQUE: By a cortical window at the dorsum of the middle phalanx (through the tendon free triangle) the impression fracture is reduced from the medullary cavity. Reduction is secured and the articular surface is supported by lattice-like arranged K‑wires. POSTOPERATIVE MANAGEMENT: Thermoplastic splint for the finger for 6 weeks, subsequently K‑wire removal, active range of motion exercises and hand occupational therapy.
RESULTS: In two case series already published, good clinical and radiological results were reported. No complications were detected in either series.
