Musculoskeletal Manifestations of Rickets:
An Eighteen-Month Observational Study
Keywords:angular knee deformity
Objectives: to determine the pattern of presentation of musculoskeletal features of rickets in a large urban health care facility.
Study design: prospective
Setting: University of Benin Teaching Hospital, Orthopaedic Unit.
Subjects: Children aged 16 or less who present at the out-patient clinic with features of rickets.
Outcome measurements: Age at presentation, sex, type of angular knee deformity, time of onset of angular knee deformity, family history of knee deformity, weight, height, body mass index (BMI), serum calcium, serum phosphate and serum alkaline phosphatase levels.
Results: Thirty seven (37) patients aged between birth and 16 years with clinical and radiological evidence of rickets were evaluated during the study period. The mean age at presentation was 3.7±2.08 years and the male: female ratio was 2.4:1 (26 male and 11 female). Windswept deformity was found to be the commonest mode of presentation in our environment, making up 51.4% of all cases seen.
Conclusion: Rickets is a relatively common cause of angular deformity of the knee. In this environment, it is commoner in males and windswept deformity of the knees is the commonest mode of presentation.
