Bilateral insufficiency fracture of coracoid process: A rare case report.

A 69-year-old man was admitted to the hospital for a left femoral neck fracture. A preliminary chest computed tomography scan showed no coracoid process fracture. The patient had no history of trauma during his hospitalization. However, subsequent in-hospital computed tomography scan revealed bilateral coracoid process fracture. The patient underwent hip replacement surgery for femoral neck fracture, while conservative treatment was administered for the bilateral coracoid process fracture. After 1-year follow-up, the patient was diagnosed with bilateral insufficiency fracture of coracoid process after ruling out other types of fractures. The fractures did not heal while functions in both shoulders were adequate. Insufficiency fracture should be considered when fractures occur without trauma, especially in the presence of associated risk factors such as chronic renal failure and osteoporosis. For bilateral insufficiency fracture of coracoid process, conservative treatment is acceptable.

Successful treatment for bilateral femoral neck insufficiency fractures: a rare lesion case report and an updated review of the literature.

BACKGROUND: The incidence of insufficiency fracture (IF) at femoral neck is low, accounting for about 5% of all insufficiency fractures, and IF at bilateral femoral neck is less common with more occurrence in athlete or serviceman. With the aging of populations, more cases of bilateral femoral neck IF have occurred recently, while the standard clinical treatment still remains lacking due to the complexity of these patients. CASE PRESENTATION: A 55-year-old male patient complained pain in his bilateral hip, with no history of trauma, glucocorticoid hormone consumption or radiotherapy, and imaging examination revealed fracture nonunion and shortening in his left femoral neck, and double fracture line on the right femoral neck. The patient received a cementless THA for the left femoral neck fracture and conservative treatment for the right side, followed by Elcatonin injection and oral administration of Carbonate D3 Granules. After 4 months of fellow-up, the patient presented improved functional scorings in bilateral hip joints, with no signs of prothesis infection or loosening. CONCLUSION: We present a rare case of bilateral femoral neck IF in a middle-aged male and the treatment is successful. The timely CT and MRI examinations of bilateral hip joints for patients was necessary for orthopedists to select proper therapeutic regimen. In addition, the choice for therapeutic regimen of bilateral femoral IF should not only be based on the professional judgement of orthopedists, but also on the wishes of patients.
