Patient reported outcomes after cheilectomy versus cheilectomy and Moberg osteotomy.

BACKGROUND

A Moberg osteotomy is a dorsal closing wedge osteotomy of the base of the first proximal phalanx that is thought to augment the effect of cheilectomy by increasing dorsiflexion and ultimately improve patient outcomes in Hallux Rigidus.

PURPOSE: The purpose of this study was to evaluate the addition of a Moberg osteotomy to dorsal cheilectomy on patient reported outcomes.

STUDY

DESIGN

Retrospective chart review.

METHODS

34 patients were identified who received a dorsal cheilectomy with or without a Moberg osteotomy (n = 17 patients, 18 metatarsophalangeal (MTP) joints per group). The Foot and Ankle Ability Measure (FAAM) was completed pre-operatively with the FAAM and Foot Function Index-Revised (FFI-R) completed post-operatively.

RESULTS

FAAM scores improved post-operatively (isolated cheilectomy pre 64.9 ± 14.7 and post 84.8 ± 15.3; cheilectomy plus osteotomy pre 63.5 ± 11.6 and post 90.5 ± 12.8; p < 0.001), and there was no difference between procedures postoperatively for the FAAM and FFI-R.

CONCLUSION

Proximal phalanx osteotomy did not enhance patient-reported outcomes in early stage hallux rigidus in addition to dorsal cheilectomy.
