Background: Fixed flexion deformity of the proximal interphalangeal joint with or without hyperextension of the metatarsao-phalangeal joint, hammertoe, is one of the most common foot deformities. Many surgical options have been recommended including the use of a more flexible PDS Orthosorb absorbable pin for fixation. The authors, using the PDS pin technique, reported some coronal angulations with painful soft corns requiring surgical correction. A new proximal interphalangeal joint arthrodesis procedure for hammer toe deformities utilizing a stiffer poly L-lactate 2-mm absorbable pin for internal fixation is presented.
Methods: Forty-seven toe procedures were done on 29 patients followed for an average of 18 (range, 10 to 36) months. Final evaluation included: physical exam, X-rays, MRI scan, AOFAS score, and a patient satisfaction survey. Results: Utilization of the stiffer poly-L-lactate absorbable pin resulted in minimal coronal angulations, no soft corns, high fusion rates and patient satisfaction.
Conclusion: The stiffer poly-L-lactate absorbable pin technique in this study was found to be superior to the published results using other methods of fixation including the more flexible PDS absorbable pin.
