Clinical Summary: Mipa kum 38 mi, distal tibia-a crush injury nei chu XC Medico-in retrograde intramedullary nail (DTN) system hmangin enkawl a ni. Soft tissue compromise nasa tak nei mahse, damlo hian kar 12 chhungin solid bony union a nei a, kar 16-ah full weight-bearing-ah a kir leh a, complication zero a nei tih a sawi. He case hian soft tissue envelope a tihchhiat hunah retrograde DTN fixation hi plate fixation aiin a tha zawk tih a tilang chiang hle.
Thuhmahruai: Distal Tibia Fractures-a harsatna awm thei
Distal tibia fracture hian tibial fracture zawng zawng zinga 7-12% a huam a, surgical challenge danglam tak a siam bawk. Distal tibia-a anatomy—wide metaphyseal region coupled with minimal soft tissue coverage on the anterior-medial aspect—chuan trauma case-ah chuan crush injury emaw, soft tissue compromise na tak emaw a awm chuan traditional open plate fixation chu a hlauhawm hle.
Tunhma lam atang khan surgeon te hian open reduction leh plate fixation an ring a, hei hian traumatized tissue hmangin anterior-medial incision zau tak a mamawh a ni. Crush injury-ah chuan he approach hian infection rates 15-25% ah a tisang a, soft tissue healing a ti buai hle. Retrograde intramedullary nailing (DTN) hian heng harsatnate hi minimally invasive ankle entry point hmangin a pumpelh a, plate fixation-a harsatna nasa ber scenario-ah chiah outcome tha zawk a pe chhuak a ni.
'Retrograde DTN hi plate fixation ai chuan a danglamna mai a ni lo—soft tissue a chhiat hunah duhthlanna tha ber a ni.' — Dr. Carlos Eduardo Vega, Attending Trauma Surgeon
