<prompt> Which of the following displacement is not seen in Colics fracture?Radial tiltVolar tiltDorsal displacementSupination  <response>: Ans. b. Volar tilt Ref: Apley 9e p773; Rockwood 6e p910-943: Campbells 10e p3058-3068: Maheshwari 3e p 95-96Volar tilt is not seen in Colics fracture.Displacements of Colles Fracture:It results in dinner fork silver fork spoon shaped deformity With six displacements; Mnemonic-DILS Dorsal displacementQ Dorsal tiitangulationQ ImpactionQ Proximal shift Lateral displacementQ Lateral tilt angulationQ SupinationQ Colles FractureColles fracture is fracture of lower end of radius at its cortico cancellous junctionQMostly occurring in post menopausal osteoporotic elderly womenQAs a result of fall on outstretched hand with wrist in extension.It is MC of all fractures In older peopleQ.Mechanism of Injury:Falling on to the outstretched hand with wrist in extension, the thener eminence takes the brunt of force. This results in fracture of lower end of radius, rotating it in to supination with the centre of rotation at the ulnar styloid.If the force continues the ulnar styloid is avulsed and triangular fibrocartilage complex is injured.Displacements of Colles Fracture:It results in dinner forksilver forkspoon shaped deformity With six displacements: Mnemonic-DILS Dorsal displacementQ Dorsal tiltangulationQ ImpactionQ Proximal shift Lateral displacementQ Lateral tilt angulationQ SupinationQPosition of immobilization in Colles fracturePalmar deviationQ FlexionPronationQUlnar deviationQComplication of Colles Fracture Joint Stiffness- Finger stiffness is NIC complicationQ.- Wrist, elbow, and shoulderQ are other joints to become stiff. Malunion is the 2nd MC complicationQ and it leads to dinner fork deformityQ Sudecks osteodystrophy Reflex sympathetic dystrophy:- It is quite common but seldom progress to hill-blown picture of sudecks atrophy.- Colles fracture is the commonest cause of sudecks dystrophy in upper limbQ. Shoulder Hand Syndrome:- Characterized by a swollen, painful, stiff hand and a frozen shoulder. Rupture of extensor pollicis longus tendonQ Carpal tunnel syndrome causing median nerve compressionQ. Carpal instabilityQ Triangular- fibrocartilage complex injuryQ and subluxation of inferior radioulnar joint. Delayed union and nonunion are extremely rare.
