There are many operative treatment options, prosthetic replacement with Austin Moore prosthesis (AMP) is one of the treatment option in this age group. Post Operative complications are thigh pain, hip dislocation & infection. Objectives: To determine the results of Austin moore prosthesis in fracture neck of femur in elderly patients in terms of mid-thigh pain. Study Design: Descriptive Case series & setting in Orthopedic Department Allied Hospital Faisalabad. Period: Study Period is from April 2008 to August 2010. Setting: All the cases done in Orthopedic department Allied & DHQ Hospital Faisalabad.

In all cases one dose of prophylactic broad spectrum antibiotic were giving. Results: 56 Patients (31 males 55.4% + 25 female 44.6) with mean age 73.08 +8.13 are Included in the criteria and were operated with same implant. After 2 monthspost operatively 40 Patients had no pain 07 (12.5%) had mild (71.4%). Pain & 08 Patients 14.3 % had moderate pain. After 03 month post operatively 43 Patients (78.2%) had no pain, 02 (3.6%) had mil, 08 Patients (14.5%) moderate and 01(1.8%) had scene.
