Objectives/Interrogation: To evaluate the outcomes of treating chronic mallet finger with swan neck deformity with Thompson procedure.

Methods: Eighteen cases of chronic mallet finger with swan neck deformity were treated with the Thompson procedure from June 2013 to December 2017. Ranges of motion of the distal interphalangeal (DIP)and proximal interphalangeal (PIP) joints were measured both pre-and postoperatively. The treatment outcomes were evaluated using Abouna and Brown criteria (Table 1 [Tab. 1], Figure 1 [Fig. 1], Figure 2 [Fig. 2]).

Results and Conclusions: AII the patients were follow-up for 4 to 22 months with an average of 12.5 months. At the final follow-up the average extension lag of the DIP joint was-6° (range,-10° to -5°), while that of the PIP joint was-4° (range,-30° to 0°). Flexion Was 61° (range,45° to 85°) for the DIP joint and 90° (range,80° to 110°) for the PIP joint. The swan neck deformity was corrected in all the cases. 2 cases were seen mild Boutonniere deformity and a dimple at the proximal tied end of the tendon graft was seen in 1 case. Assessment by Abouna and Brown criteria revealed that 15 of 18 patients were recognized as cured and 3 as improved.

Thompson procedure provides a predictable method for correcting loss of DIP joint extension with PIP joint hyperextension. It is an effective technique for treating chronic mallet finger with a swan neck deformity.
