About this study
The goal of this observational study is to learn if percutaneous transverse osteotomies for hallux valgus deformity are safe and effective. The main questions it aims to answer are:
- What is the change in clinical patient reported outcome measures after minimally invasive bunion surgery
- What severity of bunion deformity can be corrected with minimally invasive surgery
- What factors may lead to recurrence of bunion deformity
- What is the rate of complications following bunion deformity surgery
Researchers will retrospectively review a research registry containing prospectively collected clinical and radiographic deformity data collected as part of routine care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Consecutive patients | Consecutive patients aged 16 years and over, who had exhausted conservative treatment and subsequently underwent primary correction of hallux valgus (of any deformity severity) were included. Patients who underwent additional forefoot procedures eg. hammer toe corrections, distal metaphyseal metatarsal osteotomy, were included. Patients who had previously had hallux valgus surgery, or first ray degenerative joint disease were excluded. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Manchester-Oxford Foot Questionnaire (MOXFQ)
A validated patient reported outcome measure for assessment of function in hallux valgus.
The Manchester Oxford Foot Questionnaire (MOXFQ) consists of 3 domains (walking and standing, social interaction [based on the patient's self-consciousness regarding their feet/shoes as well as the overall impact on social, recreational, work, and other everyday activities], and pain), with the score in each domain ranging from 0 (best possible score) to 100 (worst possible score). An overall summary "index" score can also be calculated. The minimal clinically important difference (MCID) has been shown to be 16, 12, and 24 for the walking and standing, pain, and social interaction domains, respectively.
Measured: Patients completed the MOXFQ at 6,12 and 24 months following surgery. Patients outside of these time points were asked to complete scores at their final follow up.
Secondary outcomes (4)
Complication Data
Complication data were routinely prospective collected for all patients until discharge and categorised using a modified Clavien-Dindo complication classification.
Measured: Clinical notes were reviewed at final follow up (minimum 12 months post surgery) following surgery to assess for any complications
EuroQol 5D Health Related Quality of Life (EQ-5D)
A validated patient reported outcome measure for health related quality of life. The EQ-5D is a standardized patient-reported outcome measure (PROM) assessing health across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five levels of severity, from no problems to extreme problems. The scores are combined into a health profile and converted into a single index value reflecting overall health, where 1 represents perfect health, 0 represents death, and negative values indicate health states worse than death. The EQ-5D also includes a visual analog scale (VAS) for patients to rate their overall health.
Measured: Patients completed the EQ5D at 6,12 and 24 months following surgery. Patients outside of these time points were asked to complete scores at their final follow up(minimum 12 months following surgery).
Radiographic Deformity Correction
The intermetatarsal angle (IMA) and hallux valgus angle (HVA) were measured according to the American Orthopaedic Foot \& Ankle Society technique and categorised with regards to deformity severity. pre-operatively, six months following surgery and final follow up. Round sign and sesamoid coverage were classified according to Okuda et al. and Yildirim et al.
Measured: Specified timepoints during study (6weeks, 6months, final follow up (minimum 12 months following surgery)
Visual Analogue Scale for Pain (VAS Pain)
A validated outcome measure to assess pain. The Visual Analog Scale (VAS) for pain consists of a straight line with one end labeled no pain(0) and the other worst possible pain(100). Patients mark a point on the line that represents their pain level, and the distance from the no pain end to the mark is measured to quantify the pain. Higher scores indicate greater pain intensity, with 0 being no pain and 100 being the worst imaginable pain.
Measured: Patients completed the VAS Pain at 6,12 and 24 months following surgery. Patients outside of these time points were asked to complete scores at their final follow up(minimum 12 months following surgery).

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Manchester-Oxford Foot Questionnaire (MOXFQ) (time frame: Patients completed the MOXFQ at 6,12 and 24 months following surgery. Patients outside of these time points were asked to complete scores at their final follow up.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
