SUMMARY
Phalangeal fractures of the foot are common injuries that most frequently involve the toes and typically result from direct trauma or axial loading. Although many fractures are stable and amenable to conservative management, intra-articular involvement, displacement, or rotational deformity may significantly affect functional outcome. Diagnosis is usually established with standard radiographs. Treatment decisions depend on fracture location, articular involvement, alignment, and patient functional demands.
EPIDEMIOLOGY
Incidence
Toe fractures account for a substantial proportion of foot injuries seen in emergency and outpatient settings
Lesser toe fractures are more common than hallux fractures
Demographics
Occur across all age groups
Frequently associated with household or occupational trauma
Athletes may sustain fractures related to axial loading or repetitive stress
ETIOLOGY
Mechanisms of Injury
Direct trauma (most common):
Dropping heavy objects on the toes
Crush injuries
Indirect trauma:
Axial loading during stubbing injuries
Twisting mechanisms
Associated Conditions
Nail bed injuries and open fractures
Soft tissue contusion or laceration
Intra-articular fractures may coexist with joint subluxation or dislocation
ANATOMY
Osseous Anatomy
Each lesser toe consists of three phalanges (proximal, middle, distal)
The hallux has two phalanges (proximal and distal)
Phalanges articulate at the interphalangeal joints and contribute to balance and push-off during gait
Soft Tissue Considerations
Close relationship to the nail bed and skin increases the risk of open fractures
Extensor and flexor tendon insertions influence fracture displacement patterns
Biomechanics
Although phalanges bear less load than metatarsals, alignment is essential for normal toe-off and shoe tolerance
Malalignment may result in altered pressure distribution and chronic pain
CLASSIFICATION
Phalangeal fractures are described based on:
Toe involved (hallux vs lesser toes)
Phalanx involved (proximal, middle, distal)
Fracture pattern (transverse, oblique, comminuted)
Displacement and rotational deformity
Presence of intra-articular extension
CLINICAL PRESENTATION
History
Acute pain following direct impact or stubbing injury
Difficulty with ambulation or shoe wear
Symptoms
Localized pain and swelling
Bruising and tenderness
Pain exacerbated by weight bearing or toe motion
Physical Examination
Inspection for deformity, rotation, or shortening
Evaluation for nail bed injury or open wounds
Assessment of toe alignment during passive motion
IMAGING
Radiographs
Standard anteroposterior, lateral, and oblique views of the foot
Dedicated toe views may assist in evaluating alignment
Particular attention should be paid to joint congruity in suspected intra-articular fractures
Advanced Imaging
Rarely required
CT may be considered for complex intra-articular fractures when surgical planning is necessary
TREATMENT
Nonoperative Management
Buddy taping and rigid-sole shoe
Indicated for nondisplaced fractures without rotational deformity
Short period of immobilization
May be used for pain control in more symptomatic injuries
Most fractures of the lesser toes heal reliably with conservative treatment.
Operative Management
Indications
Open fractures
Significant displacement or malrotation
Intra-articular fractures with step-off or joint incongruity
Hallux fractures affecting joint function or alignment
Surgical Principles
Restoration of alignment and articular congruity
Fixation options include:
Kirschner wires
Mini-fragment screws
Goal is to allow early mobilization while maintaining stability
COMPLICATIONS
Malunion resulting in toe deformity
Joint stiffness, particularly after intra-articular fractures
Chronic pain with shoe wear
Nail deformities following distal phalanx injuries
PROGNOSIS
The majority of phalangeal fractures heal uneventfully with conservative management
Intra-articular involvement and malalignment are the main predictors of residual symptoms
Proper early alignment minimizes the risk of long-term functional impairment
