Insufficiency fractures secondary to prolonged alendronate use is due to inhibition of osteoclastic activity and suppressed bone turnover. Complications of fracture fixation include non-union, mal-union, and difficulty in intramedullary nail insertion. We report a technical challenge in intramedullary nailing of an obliterated femoral canal in a patient on long-term bisphosphonate treatment. The fracture site was explored. The medullary canal was re-created by drilling. Patience and caution during drilling and reaming are necessary to avoid iatrogenic fractures.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.
Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.

Bone is a multifaceted tissue requiring orchestrated interplays of diverse cells within specialized microenvironments. Although significant progress has been made in understanding cellular and molecular mechanisms of component cells of bone, revealing their spatial organization and interactions in native bone tissue microenvironment is crucial for advancing precision medicine, as they govern fundamental signaling pathways and functional dependencies among various bone cells. In this study, we present the first integrative high-resolution map of human bone and bone marrow, using spatial and single-cell transcriptomics profiling from femoral tissue.

Introduction: As a result of increased incidence of anterior cruciate ligament (ACL) injury in young athletes, there is a rise in the indications surgical ACL reconstruction procedures. The value of anterolateral ligament (ALL) reconstruction emerges as a proposed solution to prevent graft failures and improve stability in this high demanding category of patients. The purpose of this study is to present our experience with a novel hamstring auto-grafting technique, the single antegrade sling graft (SASG), for combined reconstruction of both ACL and ALL using autologous gracilis (GR) and semitendinosus (ST) grafts utilizing a single femoral tunnel and double tibial tunnels.

Background: Cementless stems are commonly used in hemiarthroplasty (HA) for femoral neck fractures. Recent studies have reported increased risk of periprosthetic fracture with cementless stems compared to cemented HA. In elective total hip arthroplasty (THA), lower proximal canal fill ratios (CFR) of cementless stems have been associated with worse outcomes.
