Slipped Capital Femoral Epiphysis and Primary Hyperparathyroidism: A Case Report

Abstract

The aim of reporting this case is to highlight the association of two disorders, primary hyperparathyroidism (PHPT) and slipped capital femoral epiphysis (SCFE). They are usually seen in two different age groups and rarely together. PHPT is a rare cause of SCFE and only 10 cases have been reported in the literature worldwide. The patient in our report is a 13-year-old girl who presented to our clinic with bilateral knee pain and a waddling gait. Subsequent investigations showed that she had PHPT and SCFE with low bone mass. On admission, a parathyroidectomy was performed; then, the slipped femoral epiphyses were fixed with satisfactory results. A systematic algorithmic approach that was illustrated in a previously published case was used. Such cases should be managed with a systematic approach based on the patient's clinical status to prevent future morbidity. A literature review was conducted by performing a Medline search of all reported cases of PHPT and SCFEs.
