Primary bone tumours arising from the lesser trochanter (LT) are rare and the literature describing them is sparse. In this paper, we describe the largest series of LT tumours describing the demographics, diagnosis and management.
Methods:
A retrospective search of prospectively maintained radiology and oncology databases was performed to identif...

... The clinical differential diagnosis of hip osteoid osteoma ranges between inflammatory and noninflammatory arthritis of the hip, aseptic osteonecrosis of the femoral head, slipped capital femoral epiphysis, radicular syndrome, stress fracture, and regional osteoporosis. The radiographic differentiation includes osteoblastoma, Brodie's and intracortical abscess, chronic osteomyelitis, callus formation due to an avulsion fracture of the lesser trochanter, eosinophilic granuloma (Langerhans cell histiocytosis), bone island, and malignancy [1,[59][60][61][62][63][64][65][66][67][68][69]. ...
The purpose of this editorial is to perform an extensive review of the pediatric literature about the diagnosis and treatment of osteoid osteoma localized in the region of the lesser trochanter, to indicate that it may appear with atypical clinical and/or imaging findings, and to present two illustrative cases, with thigh atrophy and corti-cal erosion, respectively.
... Isolated lesser trochanteric fractures in adults are considered a metastatic deposit unless proven otherwise [1]. Primary bone tumours affecting the lesser trochanter are very rare but include osteochondroma and fibrous dysplasia [2]. ...
Diagnosis Lesser trochanter avulsion fracture secondary to underlying intra-osseous haemangioma.
Osteochondromas are benign osteocartilaginous tumours, which are developmental abnormalities rather than actual neoplasms. The lesser trochanter is an extremely rare location for a solitary osteochondroma, and depending on the tumour’s size, the patient can exhibit various symptoms, including a limited range of motion. This case study describes a rare instance of a benign solitary osteochondroma of the lesser trochanter identified and managed using an excisional biopsy following Ludloff’s approach. With intraoperative fluoroscopy, we could accurately outline and remove the entire tumour mass without endangering the nearby essential tissues.
