Proximal Phalanx of the Toes, Medial View

Description

Medial anatomy of the lesser toe skeleton is presented with emphasis on the proximal phalanx and its distal articular surface, where the condylar margins flare medially and laterally to meet the base of the middle phalanx at the proximal interphalangeal joint. Proximally, the concave base of the proximal phalanx relates to the corresponding metatarsal head at the metatarsophalangeal joint, with the shaft narrowing between the metaphyses. The medial contour helps orient the digit relative to its neighbors, clarifying which surface is medial versus lateral. Bone landmarks read cleanly. That medial profile matters when you are teaching or planning anything that depends on joint congruity. Degenerative change or post-traumatic malunion at the distal condyles of the proximal phalanx can drive angular deformity and painful limitation at the PIP joint, and the condylar flare is also where fixation hardware or implant components must avoid impinging on the collateral ligament recesses. Clear depiction of the metatarsophalangeal to interphalangeal alignment supports discussion of hammer toe and claw toe mechanics, where imbalance between flexor and extensor forces concentrates load at the PIP joint and alters pressure distribution under the forefoot. Small bones, big consequences. Use this illustration in podiatry and orthopaedic anatomy teaching to orient learners to toe phalanges, joint surfaces, and medial versus lateral landmarking, and in surgical education materials that compare arthrodesis, osteotomy, or implant-based procedures at the lesser toes. It also suits publisher figure sets on forefoot deformity and postoperative alignment assessment in clinical notes or patient-facing handouts.
