| Specialty | Emergency medicine, orthopedics |
| Symptoms | Pain in lower leg, limp[1] |
| Usual onset | 9 mths to 3 yrs[1] |
| Duration | 3 to 4 wks[1] |
| Causes | Low energy injury[1] |
| Diagnostic method | Based on symptoms and examination, supported by X-rays[1] |

| Prognosis | Good[1] |
| Frequency | Relatively common[1] |
Toddler's fracture is a type of broken bone that involves the lower part of the shin bone (tibia).[1] Symptoms may include pain in the lower leg or a limp.[1] Some refuse to walk at all.[2]
The cause is often a twisting motion over a planted foot.[1] This may occur as the result tripping or other minor events.[1] It generally occurs in the distal thirds of the tibia, is undisplaced, and has a spiral pattern.[1] Diagnosis is often based on symptoms and examination, with initial X-rays appearing normal in about half of cases.[1]
Treatment is often by limiting movement of the affected leg by splinting or casting for 3 to 4 weeks.[1] Casting may occur above or below the knee.[1] Some just allow healing without immobilization.[1] Outcomes are nearly always good.[1]
Toddler's fracture is relatively common, making up about 1.5 per thousand visits by children to the emergency department.[1] It most commonly occurs in people between the age of 9 months and 3 years.[1] It was first described in 1964 by Dunbar.[3][4] There were previously concerns of an association with non accidental trauma; however, this is very rarely present.[5]
Signs and symptoms
Typical symptoms include pain, refusing to walk or bear weight and limping -bruising and deformity are absent. On examination, there can be warmth and swelling over the fracture area, as well as pain on bending the foot upwards.[6]
Pathophysiology
The proposed mechanism involves shear stress and lack of displacement due to the periosteum that is relatively strong compared to the elastic bone in young children.[7]
Diagnosis
The initial radiographical images may be inconspicuous (a faint oblique line) and often even completely normal.[6] After 1–2 weeks however, callus formation develops.
The condition can be mistaken for osteomyelitis, transient synovitis or even child abuse. Contrary to CAST fractures, non-accidental injury typically affect the upper two-thirds or midshaft of the tibia.[citation needed]
Other possible fractures in this area, occurring in the cuboid, calcaneus, and fibula, can be associated or can be mistaken for a toddler's fracture.[8] In some cases, an internal oblique radiography and radionuclide imaging can add information to anterior-posterior and lateral views.[9][10] However, since treatment can also be initiated in the absence of abnormalities, this appears to have little value in most cases. It could be useful in special cases such as children with fever, those without a clear trauma or those in which the diagnosis remains unclear.[6][11] Ultrasound has also been suggested as a helpful diagnostic tool.[12]

Treatment
Treatment consist of a long leg orthopedic cast for several weeks.[6]
History
The condition was first recognized by Dunbar and co-workers in 1964.[4] A new terminology has been proposed, which defines toddler's fracture as a subset of childhood accidental spiral tibial (CAST) fractures.[13]
