Lumbar spine disorders (LSD) might influence the outcome after total hip arthroplasty (THA). Despite a known common prevalence of LSD and degenerative hip disorders, this study investigates their mutual influence in case of co-existence with the purpose to advance surgeons planning and patient's prognosis. Patients with and without LSD were compared before and at the one-year postoperative examination. For clinical evaluation the WOMAC was assessed. The radiological analysis focused on cup anteversion and inclination. The total group included 203 consecutive patients. The overall incidence of LSD was 51.0%. Patients with LSD were on average 4.3 years older and had a 1.8 higher BMI than non-LSD patients (P<0.05). The cup positioning and the clinical results were comparable between both groups before and at the last time of follow up (P>0.05). No hip dislocations nor clinical signs of impingement were seen.We can conclude that there is a high degree of co-existence of LSD and hip disorders. However, a strong negative impact of LSD to clinical or radiologic results could not be confirmed in our study.
腰椎疾病（LSD）可能会影响全髋关节置换术（THA）后的结果。尽管LSD和退行性髋关节疾病的常见患病率已知，但本研究调查了它们共存时的相互影响，目的是改善外科医生的手术规划和患者的预后。对有和没有LSD的患者在术前和术后一年检查时进行比较。临床评估采用WOMAC量表。放射学分析重点关注髋臼前倾角和倾斜度。该总样本包括203例连续患者。LSD的总体发生率为51.0%。患有LSD的患者平均年龄比无LSD患者大4.3岁，体重指数（BMI）比无LSD患者高1.8（P<0.05）。两组在随访前和最后一次随访时的髋臼位置和临床结果具有可比性（P>0.05）。未发现髋关节脱位或撞击的临床体征。我们可以得出结论，LSD和髋关节疾病高度共存。然而，在我们的研究中，未证实LSD对临床或放射学结果有强烈的负面影响。
