Recent studies have revealed the increasing importance of sagittal spinopelvic alignment. Knowing the values of sagittal spinopelvic parameters, which are affected by ethnicity, is essential in the normal asymptomatic population. In the current study, these parameters were measured in a sample of asymptomatic Iranian population.

Seventy asymptomatic participants without complaint of musculoskeletal problems were enrolled. They had no complaint about musculoskeletal problems. Lateral full-length spinal and pelvic x–rays were taken. The following parameters were measured on x-rays and presented as mean ± standard deviation: pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), thoracic kyphosis (TK), lumbar tilt (LT) and thoracic tilt (TT).

The population consisted of 37 males and 33 females aged 26.6 ± 4.27 years. The mean values of PI, SS, PT, LL, TK, LT, and TT were 44.5 ± 10.1, 35.4 ± 6.7, 9.1 ± 7.9, 41.9 ± 14.7, 28.8 ± 8.3, 11.9 ± 7.4 and –7.5 ± 5.7 (median: –10; 5th percentile: –14; 95th percentile: 4.4) degrees, respectively. The variables were similar between males and females except for LL which was significantly higher in females (37.8 ± 16.5 versus 46.5 ± 11; P = 0.013). In addition, the linear regression model revealed age to be independently related with PI (beta = 0.344; P = 0.004) and PT (beta = 0.366; P = 0.002). PI (r = 0.344, P = 0.004) and PT (r = 0.359, P = 0.002) were positively correlated with age. Additionally, PI was positively correlated to SS, PT and LL and negatively to TT.

These findings may be used as referential values for sagittal spinopelvic parameters in the Iranian population. The positive correlation of PI with age questions the constancy of PI throughout life. However, larger studies are required.

Adult degenerative disorders of hip and spine are common. The recent studies inconsistently have
discussed about the influence of spinal disorders on total hip arthroplasty (THA). In this review, we discussed clearly
about these relationships and their effects on the most appropriate position of the acetabular component. We searched on databases and evaluated the articles about spinopelvic parameters in patients with spinal
disorders who needed THA. The literature search showed a prevalence of 21.2 % to 60.4% of low back pain (LBP) in patients, who
are candidates for primary THA. The coexistence of degenerative disease of hip and spine or other diseases can
significantly alter spinopelvic alignment. Accordingly, pain management or any other treatment in these patients
requires proper understanding about the biomechanics of the hip and the spinal and their corresponding interactions.
In this review article, we discussed about these interactions and their effects on the most appropriate position of the
acetabular component. We concluded that counseling sessions among patients, orthopedic surgeons and spine surgeons
can result in obtaining the best outcome for these individuals.
