| Abstract | ||
| Background The absence of coalition in adolescent patients with spasmodic valgus foot is challenging as it usually has nonknown etiology, and the ideal treatment method is still unclear. This work evaluated the functional outcome after the nonsurgical treatment of adolescent idiopathic spasmodic valgus foot by local sinus tarsi injection followed by manipulation and casting. Patients and Methods This retrospective study included 40 patients aged more than or equal to 10 years old, both sexes; 38 have unilateral, and two patients have bilateral spasmodic valgus feet with resistant foot pain and chronic peroneal muscle spasms. Sinus tarsi were injected with 2ml lidocaine 2% as a diagnostic test for the degree of immediate relaxation; if spasm was relieved, then injection of triamcinolone acetate 40mg plus 2ml lidocaine 2%, then manipulating the foot and casting in a position of maximum inversion of the hindfoot and plantarflexion for 6 weeks then shoes with high neck for 6 months to prevent a recurrence. Patients were functionally assessed using the American Orthopaedic Foot and Ankle Society Ankle–Hindfoot scale, with particular attention paid to the relapse of the condition 1 year after the procedure. Follow-up visits after 6 weeks, 3 months, 6 months, 12 months, and 18 months after the manoeuvre. Results The American Orthopaedic Foot and Ankle Society score was significantly higher at 3,6,12, and 18 months than before treatment (P<0.001). Immediate relaxation occurred in 37(88.1%) feet, while five (11.9%) feet were still rigid. Five (11.9%) of the corrected 37 feet relapsed during follow-up. Conclusions Nonsurgical treatment of adolescent idiopathic spasmodic valgus foot by sinus tarsi injection and casting is safe and effective in about 76% of cases, avoiding the need for hindfoot fusion in these patients. | ||
