Although total hip arthroplasty (THA) remains to be one of the most successful procedures in modern orthopedic surgery, complications may occur. Dislocation is one of the major complications. Functional costs are substantial for patients and the health care system. Berry (2001) reported on prevalence rates ranging from lower than 1% to higher than 10%.

Many factors can explain the occurrence of instability. They can be classified into patient-related, implant-related, and surgery-related factors. Advanced age, female sex, prior hip surgery, underlying causes leading to THA (eg, femoral neck fracture, avascular necrosis, hip dysplasia, and inflammatory arthritis), neuromuscular conditions that lead to muscle weakness or contractures around

Post-Operative care; All patients were monitored for vital signs, and neurovascular status, and then shifted to the ward after adequate recovery. First dressing was usually done in the third post-operative day, DVT prophylaxis protocol was strictly followed by mechanical and chemical prophylaxis.

Physiotherapy; started from second post-operative day with assistance of physiotherapist and full weight bearing was allowed for all cases, one patient was allowed for wheel chair only for 8 weeks due to periprosthetic fracture, then progressive weight bearing afterwards, this protocol was modified as per patient tolerance and stability.

X ray; was done post-operatively in 2 views (AP and Lateral). Patients were discharge home on seventh post- operative day after ensuring proper wound care, and education for rehabilitation. One patient needed to stay more than 7 days (for 5 days more due to wound leakage) which has improved and continued his routine follow
