Bunionette is a deformity of the fifth metatarsal in which there is a painful lateral bony prominence of the distal region of this bone caused by various anatomical and biomechanical changes. The aim of this study is to report on a minimally invasive technique without the use of hardware to treat these deformities. Methods. This is a case series of 18 patients, 25 feet, who underwent bunionette percutaneous surgical treatment. All patients answered the American Orthopaedic Foot and Ankle Society (AOFAS) scale and the visual analogue pain scale (VAS) preoperatively and at the last follow-up. Standard radiological evaluation included measurement of intermetatarsal (4-5 IMA) and fifth toe metatarsophalangeal (5-MTTP) angles. Time to radiographic consolidation, complications, and satisfaction rate were also documented. Results. The average follow-up was 15.9 months, the AOFAS increased from 49.6 to 92.4 and the VAS decreased from 7.7 to 1.2. It was observed that average 5-MTTP decreased from 15\u00b0 to 2.7\u00b0 and that 4-5-IMA decreased from 9.1\u00b0 to 3.3\u00b0. These outcomes showed a statistically significant difference ( P &lt; .001). The most common observed complication was the formation of a hypertrophic bone callus in the third postoperative month in three operated feet (12%). One patient had algodystrophy, which improved after conservative treatment. There were no cases of infection, neuropraxis, or recurrences. Fifteen patients rated the result as excellent, 2 as good, and 2 as regular. Conclusion. Percutaneous osteotomy of the fifth metatarsal without the use of hardware is a safe, reproducible technique and presents good clinical and radiographic results for the treatment of bunionette.<\/jats:p>\n                  <jats:p>Levels of Evidence: Therapeutic studies, Level IV: Case
