Intramedullary tibial nailing: access leh alignment, khup hmalam na

Tibial fracture-a intramedullary nailing-a surgical approach hi a pawimawh hle a, chu chu intramedullary nail chu entry point dik tak kal tlanga dah theih nan, intra-articular knee structures tihchhiat tlem nan leh fracture repositioning tha ber leh nail entry dik tak neih theih nan a ni.

Patella hian sagittal plane-a axial nail luh a veng bawk (Fig. 1a, b). Chuvangin, point-a luh dan tlangpui dang chu medial parapatellar incision hmangin a ni a, chu chuan medial to lateral nail insertion tlem a thlen a ni (Figs. 1c leh 2). Nail chu fracture atanga distal intramedullary canal a luh rual chuan proximal portion chu valgus ah a tilt a (Figure 2). A tawp berah chuan anterior compartment muscle-te resting tension hian valgus-ah hian tlem a thawhhlawk hle (Figure 3).
