Chondroblastoma is a mostly benign bone neoplasm that typically affects the second decade of life and exhibits a lytic lesion in the epiphysis of long bones. We report an extreme case of massive, destructive chondroblastoma of the proximal humerus in a 9-year-old girl. It was difficult to differentiate using imaging information the lesion from malignant bone tumors such as osteosarcoma. Histopathological examination from biopsy proved chondroblastoma. The tumor was resected after preoperative transcatheter embolization. Reconstructive procedure for the proximal humerus was not performed due to the local destruction. The present case demonstrates clinical and radiological differentiations of the massive chondroblastoma from the other lesions and histopathological understandings for this lesion.

Introduction And Importance: Multifocal fractures in a single upper extremity represent a significant clinical challenge, often resulting from high-energy impacts such as motor vehicle accidents or severe falls. These injuries require complex, multifaceted approaches in management, spanning initial acute care to long-term rehabilitation. This paper examines the complexities of diagnosing, treating, and rehabilitating multifocal upper extremity fractures, highlighting the importance of timely intervention and a multidisciplinary approach to maximize functional recovery, minimize long-term disability and the prognosis.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

Objective: To compare the clinical efficacy of the minimally invasive lateral shoulder approach and deltopectoral space approach in the treatment of proximal humerus fractures.
Methods: The clinical data of 95 patients with proximal humerus fractures admitted to the hospital from June 2018 to June 2023 were retrospectively collected. Forty-four patients were treated with a minimally invasive lateral shoulder approach (study group), and 51 patients were treated with a deltopectoral space approach (control group).

Two skeletally immature female dogs were each investigated for chronic weight-bearing thoracic limb lameness. The first patient was lame for 2 months following a tumble whilst playing, and the second patient had been intermittently lame since 3 weeks of age. In both cases, radiographic examination of the shoulder revealed fissuring of the caudal humeral head consistent with an incomplete proximal humeral Salter-Harris type IV fracture with an Enoki-mushroom-like appearance of the caudal fragment, where two heads rise from a common stem.

Background: Finite element analysis (FEA) could advance the understanding of fracture fixation and guide the choice of surgical treatment. This study aimed to compare two internal fixation methods in the treatment of displaced proximal humeral fracture (PHF) through FEA.
Methods: Three-dimensional FEA model based on the left shoulder joint of a 67-year-old female patient with PHFs and osteoporosis was adopted, in order to analyze the fixation effect and load stress distribution of internal fixation plates with open reduction and intramedullary nails without opening the fracture in the treatment of Neer III-VI PHF.
