Abstract

Objective: To see the effectiveness of press fit technique to achieve initial rigid stability for Acetabular cup in
cementless total hip arthroplasty (THA) done for Osteonecrosis of femoral head (ONFH) in our setting.
Study Design: Case series.
Place and Duration of Study: Study was conducted in UNIT 3 Orthopedic department, Combined Military
Hospital Rawalpindi from Oct 2015 to Aug 2016.
Patients and Methods: All cementless total hip arthroplasty (THA) patients operated for Osteonecrosis of femoral
head (ONFH) in UNIT 3 were included. Total of 12 patients were included in study with age ranging from 22
years to 47 years with mean age of 35.30 years. All patients were operated in lateral decubitus position.
Confirmation of adequate fit was done by visual inspection through the hole in the acetabular cup and by rocking
of the pelvis after insertion of trial cup with its attached handle.
Results: Out of 12 patients, line to line technique was found to be successful in 10 (83%) patients. Two (17%)
patients needed press fit technique.
Conclusion: Line to line technique is more successful technique for initial rigid stability in cementless total hip
arthroplasty (THA) for Osteonecrosis of femoral head (ONFH) in our setting.
