Abstract
Neck of femur fractures account for about half of all hip fractures most of them occurring in elderly patients leading to excess mortality rate within the first year after the fracture.
Hemiarthroplasty has been always considered one of the best treatment options for displaced fracture neck of femur in elderly.
Minimally invasive surgery of the hip aims to eliminate some complications of conventional and extensile exposures and also tries to facilitate more rapid rehabilitation of patients after surgery. This done by reduction of blood loss and soft tissue injury and post-operative pain.
The aim of the study is to evaluate the results of hemiarthroplasty of the hip using minimally invasive hip approaches in management of fracture neck of femur in elderly patients.
In our prospective study, we had 20 patients treated with hemiarthoplasty through minimally invasive approaches, 10 using posterior a, 5 using lateral and 5 using anterior approach. Their ages ranged from 60 to 90 years old.
Results was recorded and collected according to the HHS, excellent and good results were considered as satisfactory, while fair and poor results were considered as unsatisfactory.
High satisfactory results was obtained compared to other studies with overall mean of post-operative HHS was 88.0 ± 8.30 points.
Comparing results of our study to those reported with other studies and those concerned with studying results of conventional approaches, our results showed less post-operative pain, less blood loss, less need for blood transfusion, less hospital stay time and more cosmetic skin incision.
This study also confirmed the impact of minimally invasive approaches over hip stability when the stem properly positioned. This proved by our zero % dislocation rate in our series.
In this study, results showed no advantages over others in term of duration of surgery, stem position and complications such infection and DVT.
The final results was affected by the age of the patients, BMI, preinjury walking ability score, time lapse before operation, postoperative deep vein thrombosis (DVT) and postoperative infection.
