Peroneal tendon subluxation or dislocation is a relatively uncommon entity with multiple operative treatment methods described. This is a report of an indirect fibular groove deepening technique. ⋯ An indirect groove deepening technique is an effective way of treating peroneal tendon dislocation with good results. Patients with Worker's Compensation claims or other associated pathology have poorer outcomes.

Ankle arthroscopy is an important diagnostic and therapeutic procedure, but neurovascular injury remains a disadvantage. By understanding the anatomy of the superficial peroneal nerve (SPN) and deep peroneal nerve (DPN) the risk of nerve injury can be minimized. ⋯ This study proves that the medial midline portal is the best portal for the anterior arthroscopic procedures.

Lag screw fixation commonly is used to treat avulsion fractures of the posterior calcaneal tuberosity, but this method may not offer reliable fixation. This study compared the strength to failure of lag screws compared to lag screw fixation augmented with suture anchors in these fractures. ⋯ The use of suture anchor augmentation as described may improve the reliability of fixation in avulsion fractures of the posterior calcaneal tuberosity.

Three-dimensional fluoroscopy for evaluation of articular reduction and screw placement in calcaneal fractures.
Anatomic reconstruction of the posterior calcaneal facet after intra-articular fracture is one of the critical factors in achieving a good functional result. Intraoperative evaluation of fracture reduction and implant placement relies on direct view by standard fluoroscopy. We hypothesized that three-dimensional (3D) fluoroscopy is more accurate than conventional fluoroscopy, and equivalent to CT for determining fracture reduction and screw position in calcaneal fractures. ⋯ This new technology may be particularly useful in assessing calcaneal fractures and may lead to improved fracture reduction, less implant misplacement, and improved patient outcomes.
