Executive Summary a ni
He clinical case study hian kum upa lam damlo aiawh pahnih, complex proximal humeral fractures managed using nei te a tarlang a ni XC Medico hian intramedullary nail system a siam chhuak a . Damlo pahnihte hian osteoporosis leh fracture complexity nasa tak nei chung pawhin anatomic reduction, solid union, leh functional recovery tha tak an nei a ni.
Clinical lama thil hmuhchhuah pawimawh tak takte:
- ✓ Intramedullary nailing hian plate fixation nena khaikhin chuan osteoporotic bone-ah biomechanical stability tha zawk a pe a ni
- ✓ Minimally invasive approach hian soft tissue chhiatna leh operation hun chhung 25-30% in a tihtlem thei

- ✓ Kum hnih chhunga functional outcomes (Constant-Murley scores 62-64) hian durability leh damlo lungawina a lantir
Surgical Technique Thuhmahruai
Intramedullary (IM) nailing hian proximal humeral fractures-ah pawm a hlawh chho zel a, surgical technique dik tak hriatthiam a pawimawh hle[cite: 6]. Plate fixation ang lo takin, IM nails hian load-sharing device angin hna a thawk a , chu chu stability hi osteoporotic bone-a screw leinaah a innghat vek lo tihna a ni[cite: He danglamna bulpui hian IM nailing hi a bik takin ruh quality tihchhiat tawh damlo tarte tan a hlawkpui hle[cite: 4].
Technical Principle pawimawh tak takte
- Anatomic Reduction: Head-shaft angle dik tak siam that leh varus migration ven hi a pawimawh hle [cite: 4].
- Medial Stability: Varus angulation awm loh nan medial hinge chu siam that leh a ngai a ni [cite: 4].
- Load-Sharing Fixation: IM nail hian biological fusion ngai lovin stability a pe nghal a ni [cite: 5].
- Minimally Invasive Approach: Open plate fixation nena khaikhin chuan soft tissue trauma leh operation hun a ti tlem [cite: 4].
Osteoporotic bone-ah chuan IM nailing hian biomechanical superiority a lantir a ni[cite: 5]. Load-sharing fixation hian nail ngei pawh hian stability a pe thei a, chutih rualin callus formation a tichak bawk[cite: 5]. Hei hi plate fixation nen a danglam hle a, hei hi load-bearing a ni a, stress-shielding a thlen thei bawk.
Surgical Approach leh Entry Point te a ni
Deltoid-splitting approach hian exposure tha tak a pe a, chutih rualin rotator cuff chhiatna a ti tlem bawk[cite: 10]. Fracture chu hmuh theih a nih hnuah fluoroscopic guidance leh joystick reduction technique hmangin anatomic reduction tih theih a ni.
Medullary Canal buatsaih dan tur
Entry point chu a pawimawh hle[cite: 8]. Suraspinous fossa medial-a awm leh humeral shaft nena inmil taka dah a nih avangin nail trajectory tha ber a siam thei a ni[cite: 10]. Chumi hnuah chuan humeral canal kaltlangin guide wire chu hmasawn a ni a, sequential reaming hmangin canal chu implant insertion atan buatsaih a ni[cite: 10].
