The possible potentiation of an infection upon the metabolic consequences of trauma was tested in rats using a 2 X 2 block design which included control, femoral fracture, pneumococcal infection, and fracture plus infection groups. Infection introduced unique metabolic effects different from those of starvation, femoral fracture, or both together. Infection-induced effects included an accelerated conversion of 14C-alanine to glucose, higher serum haptoglobin, alpha2-macrofetoprotein, copper, and ceruloplasmin values, and lower serum iron, zinc, and transferrin concentrations. The first three of these infection-induced effects were diminished in rats with a femoral fracture. No measured effect of infection was increased in traumatized rats.

Background: The occurrence of periprosthetic femoral fractures (PFFs) in cementless total hip arthroplasty (THA) might be associated with the proximal femoral morphology and the pelvis. PFFs in short stem THA are associated with an increased Canal Flare Index. PFFs in straight stem THA show a decreased Canal Flare Index.

Background: To analyze the effects of the positioning of a bolt in the femoral neck system (FNS) on the short-term outcomes of middle-aged and young adults with displaced femoral neck fractures (FNFs).
Methods: This was a retrospective study involving 114 middle-aged and young adults with displaced FNFs who were surgically treated with internal fixation via the FNS in the Department of Orthopedics, Suzhou Municipal Hospital, from December 2019 to January 2023. The degree of deviation of the central axis of the femoral head and neck from the tip of the bolt (W), the tip‒apex distance (TAD) and the length of femoral neck shortening (LFNS) were measured on postoperative X-ray and computed tomography (CT) scan images.

Purpose: Standard operating procedures aim to achieve a standardized and assumedly high-quality therapy. However, in orthopaedic surgery, the aspect of temporal urgency is often based on surgical tradition and experience. At a time of evidence-based medicine, it is necessary to question these temporal guidelines.

Background: The endoplasmic reticulum stress (ER stress) has been involved in various musculoskeletal disorders including non-traumatic osteonecrosis of femoral head (NT-ONFH).
Objective: The current study aimed to investigate the association of glucose-regulated protein 78 (GRP78) as well as CCAAT/enhancer-binding protein homologous protein (CHOP) expressions in serum and femoral head (FH) tissues with NT-ONFH's severity.
Methods: We enrolled NT-ONFH patients (n = 150) alongside healthy controls (HCs, n = 150).

Purpose: To describe diagnostic approaches and management strategies for patients with primary hyperparathyroidism (PHPT) and recent fracture in England.
Methods: We developed a survey based on a patient at high fracture risk and a new diagnosis of probable PHPT. The survey was circulated among 50 secondary care professionals identified by the Society for Endocrinology Calcium and Bone special interest group.
