Background   We employed a novel curettage tool, a bent needle tip, during irrigation for enchondroma of the distal phalanx. This study aimed to evaluate our new curettage tool for treating enchondroma of the distal phalanx.Methods   Seven distal phalanx enchondromas were pathologically diagnosed at our institute. We evaluated age, gender, tumor location, affected side, clinical symptoms, Takigawa classification, size, recurrence, complications, residual pain, Tordai score, and follow-up period. We bent an 18G needle tip connected to an extension tube and syringe. The bent needle was inserted through the small hole, and the cavity for bone grafting was adequately filled with injectable calcium phosphate cement through the small hole.Results   There were five centric-type and two giant-type tumors, with a mean size of 52.7%. All patients had clinical symptoms at the initial presentation. All patients showed complete bone healing within 3 months on post-radiological examinations and were Grade 1 according to the Tordai score.Conclusions   This tool is extremely simple, and both the incision and the cortical window can be small. We recommend a bent needle tip, easily devised in any hospital, as a curettage tool for treating enchondroma in small bones, especially of the distal phalanx.
