BACKGROUND: Flatfoot deformity can cause significant functional impairment, often necessitating surgical correction. Calcaneal lengthening osteotomy is a well-established procedure; however, traditional bone grafts have limitations such as donor site morbidity and nonunion risk. Polyether ether ketone (PEEK) cages offer a novel alternative, potentially enhancing surgical outcomes through improved biomechanical properties and bone incorporation.
PURPOSE: To evaluate the efficacy of PEEK cages in lateral calcaneal lengthening osteotomy in adolescent patients.
METHODS: This prospective study included 41 adolescent patients with symptomatic flatfoot undergoing lateral calcaneal lengthening osteotomy using PEEK cages. Radiographic parameters, including calcaneal inclination angle (CIA) and talo-first metatarsal angles (TFA), were assessed preoperatively and postoperatively. Functional incorporation was evaluated using Worth et al.'s classification. Patients were followed for at least one year.
RESULTS: Postoperative radiographic assessments showed significant improvement. The median CIA increased from 3° (0°-7°) to 17° (12°-20°) (P < 0.001). TFA lateral decreased from 20° (11°-26°) to 2° (0°-8°) (P < 0.001), and TFA anteroposterior reduced from 22° (14°-28°) to 3° (0°-9°) (P < 0.001). At one-year follow-up, 92.7% of 41 patients demonstrated satisfactory incorporation (Grades III-IV). Complications included cage subsidence (7.3%) and pseudoarthrosis (2.4%).
CONCLUSIONS: PEEK cages in calcaneal lengthening osteotomy demonstrated excellent radiographic and clinical outcomes, with high incorporation rates and minimal complications.
