Xray of 37 years old male with operated fracture humerus with DCP. The xray was taken after a year of surgery.
Screw Pull Out and Nonunion in Fracture Humerus
The xray shows pulled out screws resulting in implant failure. The fracture has not united.
Two days old child, delivered at home presented with birth fracture of shaft of humerus.
Xray of Newborn With Birth Fracture
The child was treated with plaster splint.
Fracture humerus xray in 38 year old female who got this injury in motor vehicle accident.
Xray of Comminuted Fracture of Shaft of Humerus
The fracture is comminuted. THe xray shows the third butterfly fragment quite well.
Fracture of shaft of humerus in distal part of humerus in an adult skeleton.
Transverse Fracture of Humerus In Distal Part of Shaft
The xray belongs to 34 years old male who fell from bike.
Fifty six years old lady injured her arm in a motor vehicle accident and xray revealed spiral fracture of humerus.
Spiral Fracture of Lower Third HumerusThe Fracture Operated and Fixed Using Narrow DCP and Interfragmentary screw
The fracture was treated by open reduction and internal fixation using locking compression plate and interfragmentary screw. [Read more...]
There is no record available for this xray. Probably patient already had a knail in humerus for some old healed fracture and had a fresh bullet injury.
Broken Knail Humerus Fracture Bullet Pellets
Three weeks post injury xray of right humerus of a 46years old male being treated with non operative method.
Uniting Fracture of Shaft Of Humerus
The xray was taken between change of cast at 3 weeks. Callus formation is visible. The fracture eventually united well.
It is image that has not been taken with good quality camera but is interesting one. It is an xray of humerus in 15 year old girl that was fractured about 2 yrs back and was treated by some osteopath.
The xray showed an atrophic non union of distal third of humerus. The fracture was treated with open reduction and internal fixation using dynamic compression plate, and bone grafting
Following xray is of 67 years old man who fell in bathroom. He presented in the out patient department three days after the injury with complaint of pain and swelling in the upper part of the arm. There was substantial bruising on the arm and swelling was noted.
The xray revealed comminuted fracture of upper end of humerus.
The patient was advised closed reduction and internal fixation using an interlock nail but patient refused for surgery.
If after fixation of a fracture, there is failure to unite within certain amount of time, there is danger of implant getting failed.
With improved qualities of implants, meticulous surgical techniques and careful postoperative protocols, the failures can be reduced.
But still failures do occur.
After a fracture is fixed there is kind of race between fracture union and implant fatigue. Fatigue is the progressive and localized structural damage that occurs in materials when a material is subjected to cyclic loading.
In other words every time an implant is subjected to stress, there occurs a damage to it. Repetitive damage accumulates over the periods and ultimately leads to breakage of the implant.
This is one kind of fixation failure. [Read more...]
