Tendon split lengthening technique for flexor hallucis longus tendon rupture

Flexor hallucis longus (FHL) tendon rupture is a challenging injury to lead with clawing of the great toe when the FHL tendon is repaired too tight. When the diagnosis is delayed, the tendon ends may not be opposable because of contracture or poor tendon tissue. A technique to reconstruct FHL tendon rupture without a free tendon graft is described. A split tendon lengthening is ...

Radial extracorporeal shock wave therapy is efficient and safe in the treatment of fracture nonunions of superficial bones: a retrospective case series

A substantial body of evidence supports the use of focused extracorporeal shock wave therapy (fESWT) in the non-invasive treatment of fracture nonunions. On the other hand, virtually no studies exist on the use of radial extracorporeal shock wave therapy (rESWT) for this indication. We retrospectively analyzed 22 patients treated with rESWT for fracture nonunions of superficial ...

Fixation in slipped capital femoral epiphysis avoiding femoral-acetabular impingement
