Osteoid Osteoma Mimicking Triangular Fibrocartilage Complex Injury: Diagnosis and Review of Treatment

Abstract

We report the case of osteoid osteoma (OO) with ulnar styloid involvement. A review of the literature has been made with the aim of defining the special behaviour of OO when it is near the articular surface. That behaviour can affect the diagnosis, masking the real etiology of the pain, delaying the diagnosis, missing the diagnosis, or what is more serious, conducting an inadequate treatment. We propose a treatment algorithm conducted based on the localization near or far from articular surface and the superficial or deep localization.

Osteoid Osteoma of the Distal Humerus Mimicking Sequela of Pediatric Supracondylar Fracture: Arthroscopic Resection—Case Report and A Literature Review

“…They account for approximately 13% of all osteoid osteomas [6]. The occurrence of OO in uncommon locations presents a diagnostic challenge and usually there is significant time delay between symptom initiation and diagnosis due to the lack of clinical signs and radiographic features that exist in the well-established classical hallmarks of an extra-articular lesion [2–4, 7, 8]. In treating intra-articular OO, no differences have been reported between using open or an arthroscopic approach [6, 9].…”

Osteoid osteoma of the pisiform: A case report

“…Osteoid osteoma (OO), first described by Jaffe HL, et al in 1935, 1 , 2 , 3 is an uncommon benign bone-forming tumor of the musculoskeletal system with uncertain etiology. 1 , 4 It accounts for 3%–4% of all primary bone tumors, 1 , 5 and 10%–14% of all benign bone tumors. 1 , 6 OO most commonly involves long bones, 2 , 4 , 6 , 7 especially proximal femur and tibia.…”

“… 1 , 6 OO most commonly involves long bones, 2 , 4 , 6 , 7 especially proximal femur and tibia. 5 , 8 It is seen predominantly in the second and third decades of life, 5 , 6 , 8 especially males. 1 , 8 Male:female ratio is 2:1.…”

“… 1 , 8 Male:female ratio is 2:1. 2 , 5 , 6 OO constitutes 25% of all primary bone tumors of the carpal region, 2 , 9 although only 19%–31% of all OO cases involve the upper extremity. 5 10% of all OO involves the hand, 1 often metacarpals and proximal phalanges.…”

“…2 , 5 , 6 OO constitutes 25% of all primary bone tumors of the carpal region, 2 , 9 although only 19%–31% of all OO cases involve the upper extremity. 5 10% of all OO involves the hand, 1 often metacarpals and proximal phalanges. 2 Although quite rare (2%), 1 common sites of OO in the carpal region are scaphoid and capitate bones.…”
