“…26 There are various types of fixation used in MCO, but regardless of method, union rates after MCO are high, with studies reporting rates up to 97% to 100% with comparable rates of return to activity, hardware removal, and functional outcomes. 1,73,105,107 One risk of MCO is neurovascular injury. A lateral incision is usually placed directly over the planned osteotomy site, and one study showed a safe zone using a reference point that is one-third the distance from the tip of the lateral malleolus to the posterior inferior margin of the calcaneus.…”

Adult-acquired flatfoot deformity (AAFD) comprises a wide spectrum of ligament and tendon failure that may result in significant deformity and disability. It is often associated with posterior tibial tendon deficiency (PTTD), which has been linked to multiple demographic factors, medical comorbidities, and genetic processes. AAFD is classified using stages I through IV. Nonoperative treatment modalities should always be attempted first and often provide resolution in stages I and II. Stage II, consisting of a wide range of flexible deformities, is typically treated operatively with a combination of soft tissue procedures and osteotomies. Stage III, which is characterized by a rigid flatfoot, typically warrants triple arthrodesis. Stage IV, where the flatfoot deformity involves the ankle joint, is treated with ankle arthrodesis or ankle arthroplasty with or without deltoid ligament reconstruction along with procedures to restore alignment of the foot. There is limited evidence as to the optimal procedure; thus, the surgical indications and techniques continue to be researched.

“…While some lateral locked plates without compression have been discussed in the literature, currently no studies compare the outcomes of a lateral locked compression device to traditional fixation methods for calcaneal displacement osteotomies. 3,13 The primary purpose of this study will be to retrospectively compare clinical outcomes of these 2 fixation methods. Secondarily, an analysis of implant costs alone as well as a comparison to the cost of returning to the operating room for removal will be performed.…”

“…1 Alternative fixation methods have been developed, such as lateral step plates and blade plates, but few comparative studies are available. In a cadaver study, Konan and colleagues 21 found that a lateral locked step plate was stronger that a single cannulated 7-mm screw. One study by Abbasian and colleagues 1 compared fixation methods performed following open calcaneal osteotomies using headed screws, headless screws, or a lateral step plate.…”
