RESUMEN

Objective To study correlation between biochemical markers of bone metabolism and postmenopausal osteoporot-ic vertebral fractures.Methods The clinical data of 100 cases with postmenopausal osteoporotic were study retrospectively.Fifty patients were postmenopausal osteoporotic,the rests were postmenopausal osteoporotic vertebral fractures.Lumbar spine,hip BMD,serum P1NP,β-CTX,N-MID,25-(OH)VitD and Ca2 + were recorded.Results There was a significant difference among ser-um P1NP,β-CTX and 25-(OH)VitD(P 0.05).Conclusion Serum P1NP and 25-(OH)VitD could predict risk of postmenopausal osteoporotic vertebral fractures.Biochemical markers of bone metabolism combined with BMD could reduce postmenopausal osteoporosis fractures.

RESUMEN

BACKGROUND: Heterotopic ossification (HO) is common following primary total hip arthroplasty (THA) in patients with ankylosing spondylitis (AS), which may cause certain influence on functional recovery.OBJECTIVE: To explore the risk factors for HO after primary THA in AS patients.METHODS: The clinical and radiological data from 87 patients (132 hips) with AS undergoing primary THA between June 2011 and December 2015 were retrospectively analyzed, and followed up for more than 6 months. The radiological information included preoperative and postoperative hip anteroposterior and lateral radiographs. The presence of HO surrounding the prosthesis was evaluated on the radiographs at the last follow-up and graded according to the Brooker classification. Risk factors for HO were divided into invariable factors (age, sex, course and with or without ankylosed hip) and variable factors (preoperative C-reactive protein level, preoperative erythrocyte sedimentation rate, intraoperative blood loss, operation time, prosthesis types and anesthesia methods) to determine the pertinent risk factors.RESULTS AND CONCLUSION: (1) Totally 43 hips (32.6%) were found to have developed into HO. (2) Invariable risk factors including male (P=0.029), preoperative ankylosed hip (P < 0.001), and course (P=0.029) increased the prevalence of HO. Among the variable risk factors, prolonged operation time (P=0.031) and general anesthesia (P=0.003)were associated with the increased occurrence of HO. Age, preoperative C-reactive protein level and erythrocyte sedimentation rate, intraoperative blood loss, and prosthesis types had no obvious correlation with HO. (3) These results suggest that to prevent the formation of HO following THA in AS, efforts to reduce the operation time and avoid general anesthesia should be considered.
