A stiffer poly-L-lactate absorbable pin offers a superior surgical solution for hammertoe deformities, reducing complications like coronal angulations and soft corns. This technique demonstrates high fusion rates and patient satisfaction compared to other fixation methods.

Area of Science:

Orthopedic Surgery
Podiatric Surgery
Biomaterials Science

Background:

Hammertoe, a common foot deformity involving proximal interphalangeal joint (PIPJ) fixed flexion, presents surgical challenges.
Previous PDS Orthosorb absorbable pins for PIPJ arthrodesis resulted in coronal angulations and painful soft corns.
A novel technique using a stiffer poly L-lactate pin for PIPJ arthrodesis in hammertoe deformities is introduced.

Purpose of the Study:

To evaluate the efficacy of a stiffer poly L-lactate absorbable pin for proximal interphalangeal joint arthrodesis in correcting hammertoe deformities.
To compare the outcomes of this new technique with previously used fixation methods, specifically the PDS Orthosorb pin.

Main Methods:

A prospective study involving 47 toe procedures on 29 patients.

Follow-up averaged 18 months (range, 10–36 months).

Evaluations included physical examination, X-rays, MRI, American Orthopaedic Foot & Ankle Society (AOFAS) scores, and patient satisfaction surveys.

Main Results:

The poly-L-lactate pin technique led to minimal coronal angulations.
No instances of painful soft corns were reported.
High rates of joint fusion and significant patient satisfaction were achieved.

Conclusions:

The stiffer poly-L-lactate absorbable pin technique is superior to other fixation methods, including the more flexible PDS absorbable pin, for hammertoe correction.
This method effectively addresses hammertoe deformities with improved outcomes and patient satisfaction.
