Simple bone cysts of the proximal humerus presented with limb length discrepancy: A case report.

Background: Simple bone cysts (SBC) are benign tumor-like bone lesions typically identified in children. While SBC may lead to growth disturbances or growth arrest, such cases are uncommon. The mechanisms behind these observations remain unclear.

Radiographic outcomes of the treatment of complex femoral shaft fractures (AO/OTA 32-C) with intramedullary nailing: a retrospective analysis of different techniques.

Objectives: To assess the results of open versus closed reduction in intramedullary nailing (IMN) for complex femoral fractures (Arbeitsgemeinschaft für Osteosynthesefragen Foundation/Orthopaedic Trauma Association [AO/OTA]: 32-C) and to determine the factors involved in bone healing.

Methods: This retrospective study involved 47 consecutive patients with complex femoral diaphyseal fractures who underwent reduction and fixation.

Results: All open-reduction and 12 closed-reduction patients (52.

and effectiveness of a novel injectable calcitonin-loaded collagen/ceramic bone substitute.

This study aimed to evaluate the effectiveness of a novel calcitonin-loaded calcium phosphate composite bone cement and . The novel composite bone cements were composed of NuROs injectable bone graft substitute, type I collagen, and/or salmon calcitonin. The setting time, porosity, wettability, compressive strength, compressive modulus, and crystallographic structures of cement specimens were determined.

Adult Idiopathic Bilateral Coxa Vara with Hip Osteoarthritis Treated with Bilateral Proximal Femur Osteotomy: A Case Report.

Case: We reported a case of a 25-year-old woman with idiopathic bilateral coxa vara who had initial presentation of hip osteoarthritis. She was later treated with bilateral subtrochanteric valgus osteotomy. A good functional outcome was recorded without nonunion or deformity recurrence.

A new fish scale-derived scaffold for corneal regeneration.

The purpose of this study is to develop a novel scaffold, derived from fish scales, as an alternative functional material with sufficient mechanical strength for corneal regenerative applications. Fish scales, which are usually considered as marine wastes, were acellularized, decalcified and fabricated into collagen scaffolds. The microstructure of the acellularized scaffold was imaged by scanning electron microscopy (SEM).
