    Author: Medina JA, Lorea P, Elliot D, Foucher G.
    Journal: J Hand Surg Am; 2016 Jun; 41(6):e123-7. PubMed ID: 26972556.
    Abstract:
    PURPOSE: To review results at least 6 years after physiolysis for treatment of the delta phalanx associated with clinodactyly. METHODS: We present 22 cases of clinodactyly treated with physiolysis in which we removed the central part of the epiphysis, which is the portion restricting longitudinal growth unilaterally and inducing progressive finger deviation, and placed a fat graft in the resultant defect. RESULTS: This retrospective study reports the results of early physiolysis in 27 fingers with radial clinodactyly, including 17 fingers from 17 patients previously reported and 10 little fingers from 5 additional patients. All patients had a minimum follow-up of 6 years. Mean preoperative angle was 38° (range, 25° to 47°). At final follow-up, mean angle was 8° (range, 0° to 24°), a mean correction of 79%. Twelve fingers in 9 patients had more than 10° of deformity at final follow-up, whereas 15 fingers in 13 patients had a residual deformity of less than 10°, which is effectively full correction of a clinodactyly. No patient required a closing wedge osteotomy later for insufficient correction. CONCLUSIONS: These accumulative findings confirm our previous preliminary report. Early physiolysis is a quick and simple procedure that allows for growth and partial but often adequate correction of the clinodactyly. The correction occurs slowly over a period of years, which can be seen as a disadvantage, and requires careful counseling of the parents. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
