Outcome and Prognosis

The overall outcome and prognosis of a UBC is good. The lesion is believed to resolve spontaneously in most cases if given enough time. Cases that present to the orthopedic surgeon are typically patients who demonstrate a combination of a cyst that has caused cortical thinning and the right stressful event, such as being tackled while playing football. In general, treatment may be summarized as doing nothing more than trying to promote natural healing. The flexible intramedullary nail studies mentioned earlier may do nothing more than mechanically support the bone while the natural healing process occurs (see Surgical therapy, Comparative studies).

Future and Controversies

Despite the extensive literature available on this common benign bone tumor,   much remains to be learned about UBCs. As Bensahel stated, "The solitary bone cyst has not revealed all its secrets."73 Among the information to be determined are the following: 

  • What is the root cause of the UBC lesion?
  • Does a genetic basis to the problem exist?
  • Should pathologic fractures of the long bones (secondary to a UBC) be treated via immediate flexible intramedullary nailing?

These and similar questions will require a far more coordinated research effort than has been demonstrated in the past. A multicenter study (a combined effort of the Shriner's Hospital System and the Pediatric Orthopaedic Society of North America) holds some promise of refining the treatment approach to a UBC.
