Toe fractures are single in kind of the most common fractures diagnosed by means of primary care physicians. In the same rural family practice, (1) toe fractures comprised 8 percent of 295 fractures diagnosed; in an Air Force family practice residency program, (2) they made up 9 percent of 624 fractures treated. Published studies allude to that family physicians can manage greatest in number toe fractures with good deductions (1,2)

Anatomy

The first toe has simply two phalanges; the second by the agency of the fifth toes generally have three moreover the fifth toe sometimes can have alone two (Figure 1). Flexor and extensor tendons insert at the proximal portions of the middle and distal phalanges. These tendons may avulse small fragments of bone from the phalanges; they also can be injured when a toe is fractured. Abductor, interosseus, and adductor muscles insert at the proximal aspects of each proximal phalanx. The struggle of these muscles occasionally exacerbates fracture displacement. Sesamoid bone generally are instant within flexor tendons in the first toe (Figure 1 top) and are plant less commonly in the flexor tendons of other toes. In children, a physis (i.e., cartilaginous growing center) is present in the proximal part of each phalanx (Figure 2)

Differential Diagnosis

The same mechanisms that occasion toe fractures may cause a ligament sprain, contusion, dislocation, tendon injury, or other fine tissue injury. Radiographs often are required to distinguish these injuries from toe fractures. Stres fractures can meet the eye in toes. They typically involve the medial base of the proximal phalanx and usually flash on the mind in athletes. Stress fractures have a more insidious storm and may not be visible forward radiographs for the first couple to four weeks after the injury.

History and Physical Findings

mostly toe fractures are caused through an axial force (e.g., a stubbed toe) or a crushing injury (eg from a falling object) Joint hyperextension, a les usual mechanism, may cause spiral or avulsion fractures. everyday presenting symptoms include bruising, swelling, and throbbing pain that worsens with a conditioned position, although this type of pain also may fall out with an isolated subungual hematoma. Although tendon injuries may accompany a toe fracture, they are uncommon

Physical examination should include assessment of capillary refill; delayed capillary refill may indicate circulatory compromise. The skin should be inspected for make open wounds or significant injury that may lead to skin necrosis. The nail should be inspected for subungual hematomas and other nail injuries. Deformity of the digit should be noted; principally displaced fractures and dislocations existing with visible deformity. Nondisplaced fractures usually are les apparent; however, greatest in number patients with toe fractures have point tendernes throughout the fracture site. The localized tendernes of a contusion may mimic the point tendernes of a fracture. Application of a soft axial loading force distal to the injury (i.e., compressing the distal phalanx toward the foot) may distinguish contusions from fractures. If this maneuver causes sharp pain in a more proximal phalanx, it proposes a fracture in that phalanx.

Radiographic Findings

Radiographic studies of a toe should include anteroposterior, lateral, and oblique views (Figure 1) A combination of anteroposterior and lateral views may be best to control out displacement. However, overlying shadows oftentimes make the lateral view difficult to interpret (Figure 1 center) In many cases, anteroposterior and oblique views are the principally easily interpreted (Figure 1, top and bottom).

Fractures of the less toes are four times as public as fractures of the first toe. (3) greatest in quantity toe fractures are nondisplaced or minimally displaced. Comminution is universal especially with fractures of the distal phalanx. Displaced spiral fractures generally display shortening or rotation, whereas displaced transverse fractures may display angulation. In children, toe fractures may involve the physis (Figure 2)

Fractures of multiple phalanges are used by all (Figure 3). Therefore, phalanges and digits adjacent to the fracture must be examined carefully; joint surfaces also must be examined for intra-articular fractures (Figure 3) Patients with intra-articular fractures are more likely to evolve long-term complications.

Indications for Referral

Patients with circulatory compromise require juncture referral. Toe fractures of this impressed sign are rare unless there is an unclose injury or a high-force crushing or shearing injury. Patients with interpret toe fractures or fractures with overlying skin necrosis are at high risk for osteomyelitis. If there is a break in the skin near the fracture site, the pain should be examined carefully. If the harm communicates with the fracture site, the patient should be referr In an practice sites, family physicians manage lay open toe fractures; a discussion about the management of this mark of injury can be establish elsewhere. (3,4) Patients also may require referral because of delayed complications as it was as osteomyelitis from open fractures, persistent pain after healing, and malunion. fractures of the first toe
