Radiographic Evaluation and Splinting for Middle Phalanx Fractures

Initial Assessment and Imaging

Three-view radiographs (PA, lateral, and oblique) are essential for middle phalanx fractures to detect displacement, angulation, and articular involvement, as recommended by the American College of Radiology 1
An internally rotated oblique projection in addition to standard views increases diagnostic yield for phalangeal fractures, according to the American College of Radiology 1

Use a rigid finger splint that immobilizes the proximal interphalangeal (PIP) joint while allowing metacarpophalangeal (MCP) joint motion, as suggested by Praxis Medical Insights 2
The splint should be padded and comfortably tight but not constrictive, as recommended by Praxis Medical Insights 2

Begin active finger motion exercises immediately for buddy-taped fractures, as advised by Praxis Medical Insights 2
Active motion does not adversely affect adequately stabilized fractures and is extremely cost-effective, according to Praxis Medical Insights 2 and 3

Rigid splinting (if required) should be continued for 3-4 weeks with radiographic follow-up, as recommended by Praxis Medical Insights 4
Obtain radiographic follow-up at approximately 3 weeks to assess healing, as suggested by Praxis Medical Insights 4 and 2

Over-immobilization, such as rigid splinting when buddy taping would suffice, leads to unnecessary stiffness, as warned by Praxis Medical Insights 3
Inadequate initial radiographs, such as obtaining only two views, are insufficient; obtain three views including oblique projections, as recommended by the American College of Radiology 1

The American Academy of Orthopaedic Surgeons recommends beginning active finger motion exercises immediately for all unaffected joints to prevent finger stiffness, as finger motion does not adversely affect adequately stabilized fractures and provides significant impact on patient outcome 5, 6
Immediate active motion exercises for unaffected fingers are crucial, as delayed motion increases the risk of hand stiffness 5, 6
The American Academy of Orthopaedic Surgeons suggests that hand stiffness can be very difficult to treat after fracture healing, requiring multiple therapy visits and possibly surgical intervention, emphasizing the importance of early active motion 5, 6
Transition to aggressive finger and hand motion exercises when immobilization is discontinued to facilitate optimal outcomes, as recommended by the Annals of the Rheumatic Diseases 7

In children with healing middle phalanx fractures, the interval between radiographic examinations (e.g., obtaining a follow‑up X‑ray at 6 weeks versus more frequent imaging) does not affect clinical outcomes such as pain, function, or deformity once initial healing is confirmed. This recommendation is based on evidence from the American Academy of Orthopaedic Surgeons literature. 8
