Abstract:
1. A surgical method for repairing a fractured shoulder joint, comprising the following steps: a) using repair equipment comprising: a humeral rod comprising at least one hole formed in a metaphyseal portion in an anteroposterior direction thereof; a guying subassembly, two traction subassemblies, and two pressing subassemblies, each of these subassemblies comprising a needle and a thread connected to said needle, the thread forming a loop comprising two strands connected to the needle at first ends and connected to each other at second ends, opposite the first ends; b) connecting the thread of the guying subassembly to a humeral diaphysis of a fractured shoulder joint; c) placing the humeral rod in a medullary cavity of a humerus of the joint; d) engaging the thread of a first traction subassembly through at least one of a lesser tuberosity of the humerus and a tendon of a subscapularis muscle, allowing part of the loop formed by said thread to protrude from the at least one of the lesser tuberosity of the humerus and said tendon, and making said thread exit through the lesser tuberosity of the humerus, then engaging the thread in a protruding portion of the loop so as to form a choker knot with said loop; e) engaging the thread of a second traction subassembly through at least one of a greater tuberosity of the humerus and a tendon of a supraspinatus muscle, allowing part of the loop formed by said thread to protrude from the at least one of the greater tuberosity of the humerus and said tendon, and making said thread exit through the greater tuberosity of the humerus, then engaging the thread in the protruding portion of the loop so as to form a choker knot with said loop; f) engaging the thread of a first pressing subassembly through the tendon of the subscapularis muscle, allowing part of the loop formed by said thread to protrude from said tendon, then engaging said thread through the hole in the humeral rod, making it pass around said humeral rod, making it exit through the lesser tuberosity of the humerus and engaging the thread in said protruding portion of the loop so as to form a choker knot with said loop; g) engaging the thread of a second pressing subassembly through the tendon of the supraspinatus muscle, allowing part of the loop formed by said thread to protrude from the tendon, then engaging the thread through the hole of the humeral rod, making it pass around said humeral rod, making it exit through the greater tuberosity of the humerus and engaging the thread in said protruding portion of the loop so as to form a choker knot with said loop; h) while the joint is in a neutral rotation or an external rotation, contacting the greater and lesser tuberosities on the humeral rod without fixing thereto; then pulling on the threads of said traction subassemblies so as to tighten the aforementioned choker knots and obtain a balance of the muscle tensions produced by the subscapularis muscle, the supraspinatus muscle, and an infraspinatus muscle then knotting said threads together while preserving that balance; i) stretching the threads of the pressing subassemblies so as to tighten the aforementioned choker knots, then knotting the thread of the first pressing subassembly to the thread of the second traction subassembly, and knotting the thread of the second pressing subassembly to the thread of the first traction subassembly; and j) engaging the thread of the guying subassembly through the tendon of the subscapularis muscle from the outside in, and through the tendon of the supraspinatus muscle, from the inside out, then stretching that thread and knotting it with itself.
