Case: We report a 15-year-old female patient who underwent femur lengthening with a stainless steel intramedullary lengthening Stryde nail that broke at the end of the lengthening course and required removal. Given the solid noncannulated nature of the nail, this required special strategy to remove broken parts., Conclusion: Stryde nails are stainless steel lengthening nails that were developed to allow more freedom with weight bearing. Regardless of this change, hardware failure remains possible. In addition to maintaining regenerate integrity, a surgeon must be creative when attempting to remove solid nail types because many techniques for removing failed hardware were developed for cannulated devices., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/B744)., (Copyright © 2021 by The Journal of Bone and Joint Surgery, Incorporated.)

Case: We describe a case of 2 individually rare diseases existing comorbidly in the form of congenital pseudarthrosis of the tibia (CPT) coincident with cleidocranial dysostosis and provide a review of the literature, including the sole preexisting documented coincidence., Conclusion: Understanding, treatment, and surgical protocol of CPT have changed considerably since this comorbidity was last reported. Updates include synostosis, periosteal grafting, the use of bone morphogenetic protein, and bisphosphonates. Our case varies from the previous in associated disorder and family history. The relationship between CBFA1 and RUNX2 genes may hold the key, but further study is needed., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/B712)., (Copyright © 2021 by The Journal of Bone and Joint Surgery, Incorporated.)
