Minimally invasive fasciotomy for symptomatic tibialis anterior muscle hernia.

Symptomatic muscle herniae are an uncommon cause of chronic exercise induced leg pain. The most common site for muscle hernia is the tibialis anterior muscle. This study evaluates the outcome of a minimal incision fasciotomy in patients with a symptomatic muscle hernia of the tibialis anterior muscle, and their return to normal daily activities including sport. The study reports mid-term results in a series of 22 consecutive patients (17 males and 5 females, median age: 22 years) with a unilateral tibialis anterior MH who had undergone minimally invasive fasciotomy between 2008 and 2019. Clinical outcomes were assessed with SF-36 and European Quality of Life-5 Dimensions scale (EQ-5D). The ability to participate in sport before and after surgery, and the time to return to training (RTT) and to sport (RTS) were recorded. At a median follow up after surgery of 23 months, both questionnaires showed a statistically significant improvement (P < 0.005). At the latest follow up, 16 of patients (73%) had returned to pre-injury or higher levels of sport/activity. The median time to return to training and to return to sport was 7 and 11 weeks respectively. No severe complications and no recurrence of symptoms were recorded. Minimally invasive fasciotomy is effective and safe for patients suffering from muscle hernia of the tibialis anterior muscle with good results in the mid-term. IV. • Symptomatic muscle herniae (MH) are an uncommon cause of exercise induced leg pain. • The tibialis anterior muscle (TAM) is most frequently affected. • We used minimal incision fasciotomy in MH of the TAM. • Patients returned to training and sport by 7 and 11 weeks respectively, without severe complications. • Minimally invasive fasciotomy is effective in patients with MH of TAM.
