Functional osteosynthesis of patella fracture

A study on functional osteosynthesis of a patellar fracture is being conducted in the emergency department of the Bishkek Clinical Emergency Hospital. For fractures without displacement or with displacement of less than 0.5 cm, conservative treatment is indicated - fixation of the limb with a splint for a period of 2-3 weeks. A fracture of the patella with a displacement of fragments by more than 0.5 mm is an indication for surgery. There are many modifications of surgical treatment, including the use of circular wire cerclages, transverse screws, multiple wire cerclages or Kirschner wires inserted at a distance from each other and purse-string sutures. The prognosis after surgery is usually favorable, the functions of the limb are completely restored. The duration of disability depends on the severity of the injury and ranges from 2 months for uncomplicated patellar fractures to 3 months for fractures with damage to the quadriceps tendon. But the frequency of complications after surgical treatment of a patellar fracture remains quite high; due to insufficient juxtaposition of bone fragments, diastasis, insufficient stability, lack of rigidity between fragments lead to non-union of bone fragments and false joint. This, in turn, leads to repeated operations and thereby extends the period of disability for an indefinite period
