Objective:
To study the clinical outcome of total hip arthroplasty(THA) for traumatic arthritis after acetabular fracture.
Methods:
From June 2010 to June 2014, 33 hips in 33 patients with traumatic arthritis after acetabular fracture were retrospective analyzed including 21 males and 12 females with a mean age of 44.6 years old. All the patients received THA with bio-prostheses. Harris score was used to evaluate the hip function of patients before and after operation, the X-ray was adopted for radiographic evaluation of the hip prosthesis.
Results:
All patients were followed up for 7 to 38 months with an average of 21.6 months. The Harris score increased from preoperative 53.6±2.4 to 94.0±3.0 at the final follow-up, the difference was statistically significant(t=55.37, P<0.05). The X-ray evaluation showed the prosthesis was in good position, no loosening of the prosthesis, dislocation and periprosthetic osteolysis.
Conclusions:
THA is an effective treatment for the traumatic arthritis after acetabular fracture;internal fixation of acetabular fractures could not be removed if it shows difficult but does not affect the prosthesis placement.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
