Insufficiency stress fractures of the foot and ankle in postmenopausal women.
Eleven consecutive patients with 12 stress fractures of the foot or ankle were seen between October 1992 and July 1995. Charts were reviewed retrospectively for clinical information. The patients were all postmenopausal females. Average age was 62 years. Onset of symptoms was not associated with a specific episode of trauma. There were eight metatarsal fractures, three distal fibular fractures, and one fracture of the medial malleolus. Fractures were confirmed by radiographs, bone scan, or MRI in 9 of the 11 cases. Nonsurgical treatment utilizing rest, decreased activity, mechanical support, and analgesics resulted in successful union of the fracture except in one patient. Only four of the patients had been taking hormone or calcium supplements before injury. Just one patient had a prior bone density measurement, although four had a definite fracture previously and two had history suggestive of previous stress fracture. A careful history considering risk factors for osteoporosis should be obtained when an insufficiency type stress fracture is diagnosed. Bone density measurements should be considered for patients with this type of injury. Appropriate medical therapy directed at the treatment of the underlying osteoporosis in addition to orthopaedic management of the fracture constitute the treatment objectives. This dual approach may prevent subsequent injury.
