BACKGROUND: The efficiency of treating @entity2001 ( @entity2001 ) is low. Depending on the choice of treatment, a positive response occurs in 20 to 80  % of cases. These rates are unacceptable, particularly considering they concern the treatment of benign lesions affecting @entity1 . Although @entity45 is one of the first known ways of treating @entity2001 , no precise qualification criteria exists for this procedure. The aim of our study is to identify which type of cyst may be most effectively treated using curettage with grafting. METHODS: A retrospective analysis was performed on 24 @entity1 referred to our clinic for @entity2001 treatment. To identify predictive factors, the group of @entity1 who positively responded to treatment (Neer stages I and II, n   =   14) were compared with the group in which recurrences occurred (Neer stages III and IV, n   =   10). RESULTS: Significantly fewer @entity1 with lesions located in the humerus (chi(2)   =   9.351; p <0.05) and without pathological facture at the time of diagnosis (p   =   0.017) were found in the group with no recurrence. The following radiological parameters were found to vary significantly between groups: cyst area (z   =   3.121; p   <   0.01), cyst index (z   =   2.213; p <0.05) and cyst diameter ratio (z   =   2.202; p <0.05). In the group with no recurrences, the mean values of these parameters were found to be lower than in group with poor response to treatment. No statistically significant differences regarding age, sex or type of bone graft (p   >   0.05) were found. Recurrences were experienced by 10 @entity1 (41.7  %) during the 3-year period after surgery CONCLUSION: In the group treated with curettage, associations were identified between worse treatment results and the location in the humerus, pathological @entity174 at the time of diagnosis, large cyst area, large cyst index and large cyst diameter.
