Correlation of back pain, compression fracture and quadriceps muscle strength with bone mineral density in renal insufficiency patients.
OBJECTIVE
The purpose of this study was to evaluate bone mineral density (BMD), bone parameters, complete blood count, erythrocyte sedimentation rate, electrolyte values, back pain, compression fracture and quadriceps muscle strength in mild and moderate renal insufficiency patients.


METHODS
Thirty-six female, 3 male, patients with the diagnosis of osteoporosis in addition to mild or moderate chronic renal insufficiency who were followed in Istanbul University, Cerrahpasa Faculty of Medicine, Physical Therapy and Rehabilitation Department, Osteoporosis and Nephrology Outpatient Clinics between March 2003 and March 2004, were included in the study. In the control group there were 17 female, 5 male patients with osteoporosis but without renal insufficiency. The inclusion criteria were to have osteoporosis, be aged between 40-70 with a creatinine clearance between 30-70 mL/min in the case group, >70 mL/min in the control group. The patients whose creatinine clearance was <30 mL/min, and whose BMD was normal or osteopenic even though creatinine clearance was >30 mL/min were excluded from the study.


RESULTS
There was no significant difference with respect to back pain, compression fracture and quadriceps muscle strength between the 2 groups. The mean value of neck BMD, T and Z score were significantly lower in the case group (P<0.05).


CONCLUSIONS
As a conclusion, PTH related bone disease had an important effect on BMD, although, the risk factors for osteoporosis were equally important. In various researches, the relationship between BMD values and history of fracture in renal osteodystrophy patients could not be shown. In our study, the history of prior fracture or fracture in the family were important risk factors for osteoporosis. Renal osteodystrophy patients had low BMD values in mild and moderate stages of the disease. Prior fracture as well as osteoporotic fractures in the family should be part of a comprehensive evaluation of the patient.
