A Study of VIRTUGUIDE System and DePuy Synthes Lapidus Implant in Participants Undergoing Lapidus Procedure

Participants with hallux valgus undergoing index Lapidus procedure using the VIRTUGUIDE System and compatible DePuy Synthes Lapidus implant(s) will be enrolled in the study. All participants will be followed up as per the surgeon's standard of care for up to 12 months after the surgery.

Evaluation of healing, that is, healing will be a combination of radiographic and clinical assessment. Healing (fusion) will be considered achieved based on surgeon interpretation of radiographic images, lack of clinical motion and no pain at the fused site indicative of failed fusion. Imaging, whether X-ray or computed tomography (CT) collected per standard of care (SOC), utilized for radiographic assessment will be collected.

The Manchester Oxford Foot Questionnaire (MOxFQ) with three domains (walking/standing, pain, and social interaction) is a standardized instrument developed and validated specifically for hallux valgus (bunions) corrective surgery. It is widely regarded as the gold standard for content and construct validity. It is designed for self (participant) completion and consists of sixteen (16) questions all of which are scored on a five (5) item Likert scale. The scores for each domain range from 0-100, with 100 representing the worst condition.

The Numeric Pain Rating Scale is a three (3) question self-administered PROM with a 10-point one-dimensional line anchored on either end by verbal descriptors ranging from "no pain" to "worst imaginable pain". The higher score indicates greater pain intensity. The three questions ask the participant to indicate the intensity of current, best, and worst pain levels over the past 24 hours.

An AE is any untoward medical occurrence (sign, symptom, or disease) in a participant that is deemed at least possibly related to the DePuy Synthes registry device, or any adjunctive implant device used during the index procedure.

An AE is any untoward medical occurrence (sign, symptom, or disease) in a participant that is deemed at least possibly related to the DePuy Synthes registry device, or any adjunctive implant device used during the index procedure. The determination of whether the AE is related to the device and/or procedure will be based upon whether a causal relationship between the device and/or procedure and the AE is at least a reasonable possibility, i.e., the relationship cannot be ruled out. A causal relationship cannot be ruled out if, in the medical judgment of the Investigator, the effect follows a reasonable temporal association with the use of the device and/or is confirmed by the improvement of the effect upon discontinuation of the clinical use of the device, and/or the effect is not reasonably explained by the participant's clinical state.

SAEs are AEs defined as having one or more of the following outcomes: death, serious deterioration in the health of the subject that has resulted in a. life-threatening illness or injury b. permanent impairment of a body structure or a body function c. hospitalization or prolongation of existing hospitalization d. medical or surgical intervention to prevent life-threatening illness or injury or permanent impairment to a body structure or a body function e. chronic disease and Fetal distress, fetal death or a congenital physical or mental impairment or birth defect.

Device deficiencies include malfunctions, use errors, and inadequate labeling. Device malfunctions are failures of the device to perform as intended and can be defined as issues with software (VIRTUGUIDE Pre-Planning Software), any breakage, malposition, migration, and/or loosening of the device.

Revision is defined as surgery following the index Lapidus procedure that involves adjustment, modification, removal, or replacement of the implanted device. Surgeries involving adjunctive implants at the first metatarsal-cuneiform joint are considered as a revision.

Reoperation is defined as any subsequent surgical procedure performed following the index surgery that does not involve adjustment, modification, removal, or replacement of the primary Lapidus implant(s), nor the addition of adjunctive fixation at the first metatarsal-cuneiform joint.

Radiographic recurrence will be considered to have occurred in those subjects with correction if both of the following criteria are met: Intermetatarsal Angle (IMA) of greater than (>)12 degree and Hallux Valgus Angle (HVA) > 15 degree.
