[Minimally invasive treatment of intra-articular calcaneal fractures with the 2‑point distractor].

OBJECTIVE

Open treatment of calcaneus fractures often has an increased risk of wound healing. Minimally invasive treatment with small incisions reduces complications.

INDICATIONS: Calcaneal fractures with malalignment/comminution >1-2 mm; broadening, varus alignment of the calcaneal length axis or shortening; emergency surgery for open fractures or compartment syndrome.

CONTRAINDICATIONS: Local or general contraindications.

SURGICAL TECHNIQUE: Standardised positioning; restoration of length/axis with 2‑point distractor under fluoroscopic control. Fragment reduction via small incisions. Fixation with 7.3 mm cannulated screws and 4.0 mm sustentaculum screws.

POSTOPERATIVE MANAGEMENT: Cast-free and no weight bearing for 6 weeks; then weight bearing in a heel off-loading shoe for another 6 weeks with physiotherapy; if needed postoperative cast until soft tissue consolidation.

RESULTS

Of 212 calcaneal fractures, 182 were treated with this technique. Wound healing complication rate was 2.7%; 4.7% of patients required secondary arthrodesis of the subtalar joint.
