Dorsiflexory Phalangeal Osteotomy for Grade II Hallux Rigidus: Patient-Focused Outcomes at Eleven-Year Follow-Up

[Distal osteotomy of the first metatarsal bone with plantarization for the treatment of hallux limitus due to metatarsus primus elevatus]

OBJECTIVE

Joint-preserving procedure with plantarization of the 1st metatarsal and improvement of range of motion.

INDICATIONS

Mild and moderate arthrosis of the 1st metatarsophalangeal joint with pain and shoe discomfort due to elevation of 1st ray and failed conservative treatment.

CONTRAINDICATIONS

Severe degenerative conditions 1st metatarsophalangeal joint with significant loss of range of motion preoperatively. General contraindications for surgical treatment/anesthesia.

SURGICAL TECHNIQUE

Dorsomedial approach to 1st metatarsophalangeal joint, mild cheilectomy and arthrolysis, v‑shaped osteotomy of metatarsal 1 from dorsal with plantarization of the metatarsal head, screw fixation from proximal dorsal to distal plantar.

POSTOPERATIVE MANAGEMENT

Full weightbearing in rocker bottom shoe for 6 weeks.

RESULTS

Improvement of range of motion from 35° dorsal extension to 50° in all cases after 6 months. Reduction of painful movement from VAS 6-7 to VAS 2-3 in 80% of patients.

Hallux rigidus - Osteoarthritis of the first MTP-joint. Surgical and patient-reported results from Swefoot

BACKGROUND

Swefoot is a Swedish national registry, that covers surgery in the foot and ankle. Surgical treatment of hallux rigidus (HR) vary within and between countries. The aim of this study was to report baseline variables for patients with HR.

METHODS

We extracted baseline characteristics, surgical procedures and patient-reported data for patients with HR entered in the registry during the period January 2014 to August 2019.

RESULTS

By August 2019, 1818 patients were reported in the registry. 68.9% of the patients were women, the average age was 58 years, the mean BMI was 26.4kg/m². 41.9% of the patients underwent a cheilectomy,19.8% a metatarsal osteotomy, 34.3% a fusion, 0.2% an arthroplasty, 0.3% Keller's procedure and 3.5% other methods. The preoperative summary score for SEFAS (Self-reported Foot and Ankle Score) was 26 and for EQ-5D (Euroqol-5 Dimension) 0.60.

CONCLUSION

This study is the first report from Swefoot regarding HR.

Patient-reported outcomes of joint-preserving surgery for moderate hallux rigidus: a 1-year follow-up of 296 patients from Swefoot

Background and purpose - Hallux rigidus (HR) may cause decreased range of motion, joint pain, and gait disturbances. There is a lack of evidence regarding the outcome of different surgical procedures for moderate HR. We report patient-reported outcomes after joint-preserving surgical procedures for moderate HR.Patients and methods - We included 296 patients registered in Swefoot (Swedish national registry of foot and ankle surgery) who underwent primary surgery for moderate HR 2014 through 2018. We extracted information on anthropometrics, grading of HR, chosen surgical procedure, and patient-reported data including the PROMs SEFAS (summary score 0-48) and EQ-5D-3L (index 0-1) preoperatively and 1 year postoperatively.Results - 115 patients underwent metatarsal decompression (i.e., Youngswick) osteotomy (YOT) and 181 underwent cheilectomy. The mean improvement in SEFAS score 1 year after surgery was 12 points (95% CI 10 - 13) for YOT and 10 points (CI 9 - 12) for cheilectomy. Also, EQ-5D improved in both groups. Patients who underwent YOT were more satisfied with the procedure (84% vs. 70% for cheilectomy, p = 0.02).Interpretation - Surgically treated patients with moderate HR improved after both YOT and cheilectomy, according to patient-reported data from Swefoot. Patients who underwent a YOT were more satisfied with their procedure. One possible explanation may be that more patients in the YOT group had a concomitant hallux valgus; however, we have no information on this.
