Pes planus, commonly associated with hindfoot valgus, is a common condition in the adolescent population. Radiologists are generally familiar with the biometric measurements of calcaneal pitch and talocalcaneal angles. However, we are not so savvy in our interpretation of the many operative procedures employed by podiatrists and orthopedic surgeons to correct the planovalgus foot. Preferred surgical techniques may vary by profession and institution with a variety of at least five different procedures used by surgeons to improve hindfoot/midfoot alignment, some of which may not be visible radiographically. Commonly encountered post-operative procedures include the calcaneal osteotomy (wedge or shift); medial cuneiform osteotomy; and arthroereisis at the sinus tarsi. While there can be a variety of implant screws and devices for each procedure, or none at all, each can be recognized radiographically with the intended result of improved plantar arch and hindfoot alignment. Unless there has been resection of an accessory navicular ossification, the tendon advancement and tenodesis procedures would often be radiographically occult. The purpose of this educational exhibit is to demystify the intention of the many surgical approaches to correct the planovalgus foot. After this review, our audience should be able to appreciate the pre-surgical indications and post-operative intentions of hindfoot alignment to better report these findings and potential complications.

As a flat and irregular bone of the appendicular skeleton, the scapula has a zonal classification of anatomy that is both useful for surgical planning as well as for distinctive locations of common and uncommon bone neoplasms (1). The acromion and glenoid together are grouped into the S2 zone of the scapula with the remaining scapular blade and spine comprising zone S1. This unique anatomy of the scapula may present a challenge to radiologists when distinguishing between benign and malignant bone tumors that are more commonly seen in long bones. As the S2 zone is much like a metaphyseal equivalent in long bones, the more common lesions encountered there will include giant cell tumors, aneurysmal bone cysts, chondroid neoplasms, and osteomyelitis. Bone lesions of zone S1 will more commonly include tumors such as osteochondromas, Ewings sarcoma, and Lymphoma (2). We present a case series of osteoid osteoma, chondroblastoma, osteomyelitis, T-cell Lymphoma, and Ewings sarcoma of the scapula and shoulder girdle in children aged 7 weeks to 17 years of age. The purpose of this case series is to present a variety of common and uncommon bone lesions of the scapula and shoulder girdle in children. Through the description and defining features of these lesions, radiologists may better familiarize themselves with the surgical anatomy of the scapula to develop a narrowed and accurate differential diagnosis of pediatric scapular tumors.
