Finger fractures are among the most common fractures of the upper limb. The number and cost of maltreated and misdiagnosed finger fractures in Sweden is unknown. The aim was to study the number, complications, causes, and cost of maltreated and misdiagnosed finger fractures, 2011-2021, in Sweden.

Claims matching the prespecified ICD-10-SE codes S62.6-7 (finger fractures) and T92.2 (sequelae after finger fracture) during the 2011-2021 timeframe were identified. The data were extracted from the Swedish National Patient Insurance Company Register and analyzed in terms of epidemiology and cost.

Of the 1621 assessed cases, 384 reported maltreated and misdiagnosed finger fractures were found. The mean age was 41 years (range 2-88). Thirty-one percent of the healthcare-related injuries occurred in emergency care, primarily due to maltreatment leading to malunion after non-operative treatment. Thirty-six percent of healthcare-related injuries occurred in specialist departments, mostly due to malunion after surgical intervention. In primary care, the leading cause was misdiagnosis, often due to inadequate examination and lack of X-ray examination. The total aggregated direct and indirect costs amounted to SEK 25 557 200 (USD 2 505 608, Euro 2 165 864, Yen 424 249 520).

CONCLUSION: Finger fractures affect people of all ages and can lead to significant socioeconomic and medical invalidity. Maltreated fractures mainly occur in emergency care (due to malunion after immobilization) and specialist care (due to malunion after surgery). Misdiagnosed fractures were more common in primary care. A suggestion for claims prevention would be improved physician education, updated guidelines regarding the use of X-rays, seeking specialist opinions in uncertain cases, evaluating surgical technique, and optimizing postoperative care could probably help reduce the number of these injuries.
