Treating recurring pathological fractures due to Albright syndrome is a very challenging endeavor, and more so when it is accompanied by poor bone quality and deformity. We hereby present the case of a 23-year-old male patient who is treated several times for recurrent pathological fractures of the femur at our center. We analyze the difficulties associated with treating a patient with poor bone quality over several years, discuss our treatment options, review the literature for similar cases and look at what we could have done differently. We weigh in on the difficulties in treating a severely deformed shepherd’s crook, the ways of achieving proper internal fixation and the dangers of using plating instead of an IM nail as suggested in the literature. Our main goal in reporting this case is to bring forth the unusual challenges encountered when treating patients with Albright syndrome and discussing the options of the orthopedic surgeons when treating these types of patients.展开更多
