Lesser Proximal Interphalangeal Joint Arthrodesis
A Retrospective Analysis of the Peg-in-Hole and End-to-End Procedures
A retrospective study was performed to compare the prevalence of complications in peg-in-hole and end-to-end arthrodesis procedures. The authors reviewed 177 second, third, and fourth proximal interphalangeal joint fusions for the correction of hammer toe deformities in 85 patients from 1988 to 1998 at the Temple University School of Podiatric Medicine. The average age of the patients was 49 years. Sixteen percent (14) of the subjects were male and 84% were (71) female. Upon follow-up, the fourth digit was generally associated with a greater number of complications for the end-to-end and peg-in-hole procedures, with the second digit being the most common site of fusion. The prevalence of complications was evaluated using contingency table analysis and expressed as a percent of total complications (27%, the end-to-end group; 17%, the peg-in-hole group). A subset of complications deemed clinically relevant was also computed. Similarly, the prevalence of clinically relevant complications for the end-to-end (10%) and the peg-in-hole (9%) procedures was not statistically significant. Therefore, this study showed no statistically significant differences in the total or clinically relevant complications between end-to-end and the peg-in-hole arthrodesis procedures.

Peg-in-Hole, End-to-End, and V Arthrodesis
A Comparison of Digital Stabilization in Fresh Cadaveric Specimens
The proximal interphalangeal joint arthrodesis is frequently performed to correct hammer toe deformities. This study was conducted to compare the inherent stability of the three proximal interphalangeal joint arthrodeses—peg-in-hole, end-to-end, and V constructs—in the sagittal plane by means of load-to-failure testing of 30 fresh-frozen cadaveric specimens fixated with a 0.045 Kirschner wire. The peg-in-hole construct was associated with significantly higher peak loads at failure compared with the other two procedures. Furthermore, the peg-in-hole construct had significantly higher stiffness values as compared with the V procedure. This study thus provides evidence that the peg-in-hole procedure is the most biomechanically stable surgical construct for proximal interphalangeal joint fusions under sagittal plane loading.
