RESUMEN
Shortening of the first ray is a potential complication associated with first metatarsal procedures. Correction of this deformity conventionally has required the use of a tricortical bone graft to lengthen the bone. Graft complications, including donor site morbidity, poor graft stability, and graft resorption, have revealed a need for an alternative procedure. The present report shows that titanium cage scaffolding has lower extremity applications beyond its previous uses in the ankle and spine. Two patients underwent surgical correction for failed first ray procedures using a titanium cage apparatus with a calcaneal autograft and other biologic agents. The scaffolds were appropriately sized to fill the defect. Patients remained non-weightbearing until radiographic evidence of healing appeared. Success was determined by diminished pain, a return to activity, ambulation, and patient satisfaction. Patients exhibited faster-than-anticipated healing, including a return to protected weightbearing activities and increased stability within 6 weeks. Titanium cage implants provide long-term stability and resistance to stress and strain in the forefoot. The implant we have described, newly applied to the first ray, is analogous to a system used in salvage of failed ankle replacements. In addition to reducing reliance on the iliac crest bone graft, the titanium cage apparatus is advantageous because it is customized to fill a defect using computed tomography scanning, thereby reducing graft failure secondary to an improper shape. These cases demonstrate the potential beneficial applications for titanium cages in failed first ray reconstruction.

Midfoot injuries are the second most common athletic foot injury documented in the published data. High-energy Lisfranc dislocations are commonly seen secondary to traumatic etiologies and disrupt the strong midfoot ligaments supporting the arch. These injuries require immediate surgical intervention to prevent serious complications such as compartment syndrome and amputation. The present case series reports a new Lapidus plate system used in 3 patients who underwent arthrodesis procedures for Lisfranc joint dislocation. Three patients in their fourth to fifth decade of life presented with a traumatic injury at the Lisfranc joint and subsequently underwent open reduction and internal fixation using the plantar Lapidus Plate System (LPS; Arthrex, Naples, FL). The LPS was placed in a predetermined safe zone, with measures taken to avoid the insertional points of the tibialis anterior and peroneus longus tendons. Radiographs were obtained for ≤6 months postoperatively and revealed consolidation across the fusion site, intact hardware, and satisfactory alignment. On examination, the corrections were well maintained and free of signs of infection. Clinical evaluation showed no indication of motion within the tarsometatarsal joint and no tenderness to palpation surrounding the fusion sites. All 3 patients successfully returned to their activities of daily living without discomfort or pain. Modern surgical treatment of Lisfranc injuries most commonly includes open reduction and internal fixation, accompanied by arthrodesis. The present case series has demonstrated that the LPS provides relief, stability, and compression of the joint in our small cohort of patients who experienced a traumatic injury to the Lisfranc joint.

Posterior tibial tendon dysfunction (tendinitis, tendinosis, or rupture) and adult acquired flatfoot deformity can manifest with a wide array of bony and soft tissue abnormalities visible on plain radiographs, ultrasound, and magnetic resonance imaging. Imaging abnormalities include various combinations of malalignment, anatomic variants, and enthesopathic and tendinopathic changes. A thorough understanding of differences between anatomic and pathologic presentations of structures in various imaging modalities is an essential tool for clinical and surgical planning.
