Solitary bone cyst: Controversies and treatment

The solitary bone cyst (SBC) has not yet revealed all its secrets. The path ogeny of the SEC is thus considered and also its evolutivity. Conservative treatment has been used in attempts to heal this tumor-like bone. In the ca se of surgery, an original technique is described. The SEC still remains my sterious in many of its aspects. At the time of this writing, nobody can pr edict the occurrence modalities of this benign bone tumor. In a similar way , the reality of this tumor-like lesion cannot be precisely described. This emphasizes the first controversial point about this lesion. Indeed, must w e consider differently the bone cysts that remain close to the growth plate and those which located in the diaphysis? Must we regard the true unicamer al bone cysts (UBCs) differently and those that are multilocular? Moreover, are the cysts located in the long bones identical to the those of the shor t cancellous bones? Alas, SEC was supposed to be a lesion in children that disappeared after growth ended. Is it still true since some cases have been reported more recently in adults? This study represents a long follow-up. It includes the different aspects of the SEC and emphasizes an original tec hnique in case surgery becomes indicated.
