Arthroscopic Management of Dysplasia Epiphysealis Hemimelica (Trevor Disease) of the Ankle.

Dysplasia epiphysealis hemimelica (Trevor disease) is a rare skeletal development disorder of childhood, characterized by irregular ossification centers, which may develop together or individually, leading to asymmetric epiphyseal cartilage overgrowth, affecting 1 side of the epiphyses or the epiphyses equivalents (the medial side being affected twice as often as the lateral), until skeletal maturity is reached. Trevor disease around the ankle is locally aggressive with a poor outcome, especially in tumors involving the articular surface. The purpose of this Technical Note is to describe the details of arthroscopic management of dysplasia epiphysealis hemimelica (Trevor disease) of the ankle.

Unveiling dysplasia epiphysealis hemimelica (Trevor's disease) in the foot and ankle: A systematic review.

Background: Dysplasia epiphysealis hemimelica is a rare non-inherited condition characterized by the unilateral predominance of osteochondromas in one or more epiphyses, with ankles and knees being the most affected joints. Treatment approaches vary based on the localization of the disease, encompassing both conservative and surgical options. Due to its rarity, there is a lack of definitive surgical guidelines or specific treatment modalities.

Isolated Dysplasia Epiphysealis Hemimelica (Trevor Disease) of the Acetabulum: Literature Review.

Dysplasia epiphysealis hemimelica (DEH), also known as Trevor disease, is a rare pathologic proliferation of cartilage with unknown etiology creating cartilaginous osteochondroma exostoses intra-articularly or juxta-articularly. Herein, we reviewed the literature about acetabular osteochondroma in children and report a case of a 9-year-old boy who presented to the orthopaedic clinic with complaints of gait disturbance, right hip discomfort, and with increasing severity and frequency of hip subluxation episodes over the course of a year. Imaging studies revealed dysplasia of the right hip with subluxation secondary to acetabular lesion.

Solitary Extraskeletal Giant Osteochondroma of the Ankle in a Four-Year-Old Boy.

Solitary extraskeletal osteochondromas are rare benign lesions usually located close to a joint and are characterized by the absence of continuity with the adjacent bone. They are usually found in the hand and feet and are extremely rarely reported in the growing skeleton. In this paper, we describe a four-year-old boy who presented with a solitary calcified tumor in the posterior part of his ankle.

A Lumpy-Bumpy Painful Ankle - Trevor Disease of the Ankle in a 9-year-old.

Introduction: Dysplasia epiphysealis hemimelica, also known as Trevor disease, is a rare skeletal development disorder of childhood, characterized by asymmetric growth of the epiphyseal cartilage in childhood. The disease can be locally aggressive at the ankle, and can result in deformity or instability. We present a case of Trevor disease involving the lateral aspect of distal tibia and talus in a 9-year-old patient, and of highlight its clinical and radiological presentation, treatment, and outcomes.

Treatment of Dysplasia Epiphysealis Hemimelica with Autologous Chondrocyte Implantation: A Case Report.

Case: We present a case of dysplasia epiphysealis hemimelica (DEH) involving the posteromedial distal femur in a 4-year-old girl. The patient underwent lesion resection with internal fixation of the articular cartilage followed by autologous chondrocyte implantation (ACI) to restore the articular surface and epiphysis. At the 7-year follow-up, the patient had no pain or difficulty with participation in sports.

A Symptomatic Swollen Ankle in an 8-year-old Male Child - A Rare Case Report of Dysplasia Epiphysealis Hemimelica.

Introduction: Trevor's disease also known as Dysplasia Epiphysealis Hemimelica is an uncommon epiphyseal affliction of childhood, developmental in nature with unknown etiology. It is an osteochondral lesion arising from the epiphyses and progressively increasing in size until skeletal maturity is reached. Surgical management is not advisable in cases, where there is absence of articular symptoms and mass evolution is present, until there is achievement of skeletal maturity.

An unconventional presentation of Hip Joint Trevor disease with the involvement of the whole capital femoral epiphysis: A case report and literature review.

Dysplasia epiphysealis hemimelica (DEH) or Trevor's disease is a rare, nonhereditary developmental disorder of skeleton affecting epiphysis and short bones of limbs and characterized by a benign overgrowth of the medial half of the epiphysis resembling osteochondroma. We herein report an unconventional presentation of Trevor's disease of the hip with the involvement of the whole epiphysis. Only a few cases of DEH with such unusual features were found in the literature.

A Case Report of Trevor's Disease in a Pediatric Patient with Hereditary Multiple Exostoses Disease.

Introduction: Hereditary multiple exostoses (HME) disease is hallmarked by cartilaginous osteochondromas secondary to an autosomal dominant mutation within the exostosin gene family. These outgrowths predominantly occur around the long bone physis. An associated disease is dysplasia epiphysealis hemimelica also known as Trevor's disease.

Bilateral Toe Walking as Presentation of Unilateral Dysplasia Epiphysealis Hemimelica of the Ankle: A Case Report.

Case: We describe a case of dysplasia epiphysealis hemimelica (DEH) of the anterior tibiotalar joint that presented as toe walking in a 6-year-old boy. Radiographs and magnetic resonance images showed substantial exostosis at the anterior ankle that blocked dorsiflexion. He underwent surgical excision and casting for equinus, restoring ankle range of motion and gait.

Dysplasia Epiphysealis Hemimelica (Trevor's Disease) in Children, Two New Cases: Diagnosis, Treatment, and Literature Review.

Dysplasia epiphysealis hemimelica (DEH), also known as Trevor's disease, is a rare nonhereditary skeletal disorder affecting one side of the epiphyses or the epiphyses-equivalents. It is often misdiagnosed for traumatic injuries, infections, or other tumors because of the nonspecific clinical features. The diagnosis is mostly based on radiographic involvement of one half of the epiphysis displaying an overgrowth; it is hard to distinguish between DEH and osteochondroma on the gross hystopathological exam.

Dysplasia Epiphysealis Hemimelica Presenting as Multiple Loose Bodies: A Case Report.

Case: A 11-year-old boy with no medical history presented with a protective limp and worsening mechanical pain in his left knee. No recent traumatic or infectious history was reported. Radiographs and ultrasonography showed multiple intra-articular loose bodies with osteocartilaginous signal.

Juvenile Dysplasia Epiphysealis Hemimelica with Multiple Ankle Free Body.

Dysplasia epiphysealis hemimelica (DEH), also known as Trevor's disease, is a rare overgrowth of cartilage that commonly arises in the epiphyseal bone of children. We report a rare case of DEH originating from a talus accompanied by multiple intra-articular free bodies in a 7-year-old patient with ankle instability. After the primary surgery for free body removal and microfracture technique for the cartilage defects in the ankle joint, the free body recurred.

Dysplasia epiphysealis hemimelica of the radial head: a rare case report.

Background: Dysplasia epiphysealis hemimelica (DEH) is a rare benign overgrowth generally affecting the epiphyses and short bones of the lower limbs. DEH in the elbow joint is extremely rare, and to date, only three cases of DEH have been reported in the radial head.

Case Presentation: In this study, we report a case of DEH located in the radial head of the right elbow of a 10-year-old boy, which was presented with elbow pain and limited range of motion.

Dysplasia Epiphysealis Hemimelica (Trevor Disease) of the Patella: A Case Report.

Case: We report a rare case of dysplasia epiphysealis hemimelica in an 11-year-old male child involving the patella. The patient noticed swelling in the right knee 6 months before presentation. On evaluation, there was a mass lesion originating from superior pole of the patella extending into the suprapatellar pouch.

Dysplasia Epiphysealis Hemimelica Can Be Controlled by Growth Modulation: A Case Report.

Case: Dysplasia epiphysealis hemimelica (DEH), or Trevor disease, is an abnormal nonmalignant overgrowth of the epiphysis on one side of the body, often confined to one half of a joint of a limb. There is no known etiology or treatment for it. We are reporting the case of a 4.

TKA in the treatment of bilateral dysplasia epiphysealis hemimelica (Trevor's Disease) of the knee in a 50-year-old man: a case report.

Background: Dysplasia epiphysealis hemimelica (DEH), also known as Trevor's disease, is a rare skeletal developmental disorder affecting the epiphyses in pediatric patients. DEH is characterized by an asymmetric osteochondral overgrowth arising from either the medial or lateral portion of an epiphysis and usually occurs in the joints of lower limbs, most commonly in the knees and ankles. However, bilateral involvement in an adult is extremely rare, and total knee arthroplasty (TKA) for a patient with DEH has been reported only once before.

Trevor's disease of the distal radioulnar joint in two children with achondroplasia.

Two children with achondroplasia who developed an abnormal bony outgrowth at the distal radioulnar joint (DRUJ), indistinguishable from an osteochondroma on histology, but the radiographic appearance, location, and asymmetry suggested the rare diagnosis of dysplasia epiphysealis hemimelica (DEH or "Trevor's disease"). One child experienced symptomatic relief with surgical excision and one was observed clinically due to lack of significant symptoms. These are the first presented cases of DEH in achondroplasia, both affecting the DRUJ.

Dysplasia epiphysealis hemimelica combined with contralateral accessory scaphoid bone: A case report and literature review.

Rationale: Dysplasia epiphysealis hemimelica (DEH), also known as Trevor disease, is a rare, developmental bone disorder of childhood.

Patient Concerns: A 9-year-old girl was admitted due to pain in front of the medial malleolus of her right foot after a long walk or distance movement, in which the pain could be relieved after rest, while it was repeated and lasted for several months.

Diagnosis: Dysplasia epiphysealis hemimelica INTERVENTIONS:: The patient underwent an open resection surgery.

Dysplasia Epiphysealis Hemimelica/Trevor Disease: Report of a Lesion Solely Involving the Lunate Bone: A Case Report.

Case: We describe the case of a dysplasia epiphysealis hemimelica (DEH) lesion affecting uniquely the lunate bone in a 16-year-old boy causing pain, stiffness, and decreased range of motion. Surgical excision was performed, leading to resolution of primary symptoms with residual limitations in terminal wrist extension.

Conclusions: From our review of the literature, we believe this case to be the first report of a DEH lesion affecting solely the lunate bone.

Benign bone tumours of tibial tuberosity clinically mimicking Osgood-Schlatter disease: a case series.

Introduction: Osgood-Schlatter disease (OSD) is a traction apophysitis of the tibial tubercle and a common cause of anterior knee pain in growing adolescents. A variety of benign neoplasms can also cause bony prominence over the tibial tubercle in adolescents that might clinically imitate OSD. Therefore, the differential diagnosis of tumours mimicking OSD is critical and considered the primary goal of this study.
