50 patients who were diagnosed as postmenopausal osteoporosis (PMOP) with lomber and/or femur neck BMD screening but have no history of PMOP treatment including calcium and vitamin D, have comorbid hypothyroidism and treated with levothyroxine at least a year were conducted for patient group.
These fractures are seen at the third frequency after distal radius fracture and femur neck fracture in the elderly (7).
Dual energy X-ray absorptiometry (DEXA) (HOLOGIC 4500 A) was used to measure BMD in the lumbar spine (L1 - L4 anterior - posterior), total femur, and femur neck. The results are expressed as g/cm2.
The geometric orientation of the implants and the choice of the angles of their placement are due to the medical practice of implant research to merge the already demolished femur neck [20, 21].
Although there is general consensus that the PLS in the middle of femur neck is optimal, there is continuing debate about the ideal position of the PLS (9-13).

Stress fractures (SFs) usually occur in the weight-bearing bones of the lower extremity, primarily sacrum (29.6%), tibia (23.6%), femur neck (9.9%), tarsal navicular (17.6%), metatarsal bones (16.2%) and calcaneus (2.8%), and tend to be unilateral.
With respect to bone health, significant differences in ACTN3 genotypes were seen in relative BMDs for femur neck (p = 0.007) and femur total (p = 0.022) and in T-scores for femur neck (p = 0.007) and total body (p = 0.017), with similar trends in femur total (p = 0.022) and total body (p = 0.030) across the genotypes (Table 3).
With respect to body composition and BMD, there were significant negative linear trends in BMI (p = 0.039), lean mass (p = 0.032), ASM index (p = 0.007), femur total BMD (p < 0.001), femur total T-score (p < 0.001), femur neck BMD (p < 0.001), and femur neck T-score (p < 0.001) across the incremental severity of bone health status.
