Clinical & Coding Specifications
Clinical Context
A middle-aged patient with a symptomatic hallux valgus deformity presents to an orthopedic foot and ankle clinic for evaluation. Conservative care including orthotic shoe inserts, activity modification, nonsteroidal anti-inflammatory drugs, and physical therapy provided limited relief. The surgeon determines that a forefoot osteotomy with corrective hardware and a lateral soft-tissue release is indicated to realign the first metatarsophalangeal joint. During the operative procedure in an ambulatory surgery center, the surgeon implants an L3390 outflare wedge prosthetic or implant component to restore metatarsal alignment and correct angular deformity. Typical workflow: preoperative evaluation with weight-bearing foot radiographs and surgical planning; informed consent and anesthesia clearance; intraoperative imaging to confirm wedge sizing and placement; implantation of the L3390 outflare wedge; closure and postoperative dressing; postoperative orthotic fitting and discharge with follow-up for wound check and radiographic assessment.
