Scapholunate (SL) ligament injury is among the most common injuries of the intrinsic ligaments of the carpus. Arthroscopic treatment in complete and nonacute injuries has had poor results. These cases have typically been treated using open surgical techniques that require a broad dorsal approach and produce soft tissue impairment, which leads to reduced wrist mobility. The development of wrist arthroscopy techniques has allowed the treatment of complete and nonacute injuries of the SL ligament, without the disadvantages of open surgery, respecting the soft tissues and avoiding injury of the posterior interosseous nerve, in an attempt to preserve the proprioception of the wrist and the secondary dorsal stabilizers. This arthroscopically assisted technique reconstructs the SL ligament using a tendon graft placed between the scaphoid and lunate and complemented by the reconstruction of the dorsal portion of the SL ligament, with the aim of creating an axial and dorsal tendinous ligamentoplasty between both bones.

We read with great interest the recent article by Vilá y Rico et al. 1 entitled "Arthroscopic Posterior Subtalar Arthrodesis: Surgical Technique," published in the February 2016 issue of Arthroscopy Techniques. Vilá y Rico et al. presented the technique 1 and their results 2 of arthroscopic posterior subtalar arthrodesis for treating adult-acquired flatfoot deformity or post-traumatic arthritis, which were treated as salvage operations after unsuccessful initial treatment. We congratulate the authors for their excellent results and their detailed description of the surgical technique. We would like to add a further potential indication for arthroscopic posterior subtalar arthrodesis, adding only two modifications to the original technique of Vilá y Rico et al. 1,2 This technique 1 could be used to treat Sanders type IV fractures of the calcaneus. 3 Primary
