Introduction: Enchondroma is a solitary, benign, and intramedullary cartilaginous tumor occurring most commonly in small bones of hands and feet contributing to 3-10% of all bone tumors. They originate from the growth plate cartilage which later on proliferates to form enchondroma. Lesions are central or eccentric and metaphyseal involvement is most common for long bones. We report a case of atypical occurrence of enchondroma in the head of femur in a young male.
Case Report: A 20-year-old male patient presented with a history of pain in the left groin for 5 months. Radiological examination showed a lytic lesion in the head of femur. The patient was managed by safe surgical dislocation of the hip, curettage with autogenous iliac crest bone graft with countersunk screw fixation. Histopathology confirmed the lesion to be enchondroma. At the latest follow-up after 6 months, the patient was symptom-free and there was no evidence of any recurrence.
Conclusion: Lytic lesions in the neck femur can have a good prognosis provided timely diagnosis and interventions are done. The present case of enchondroma in the head of femur represents a very rare differential diagnosis for the same and this must be kept in mind. So far, no such case has been reported in the literature. Magnetic resonance imaging and histopathology are of the essence to confirm this entity.

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).

Alcoholic osteonecrosis of the femoral head (AIONFH) is caused by long-term heavy drinking, which leads to abnormal alcohol and lipid metabolism, resulting in femoral head tissue damage, and then pathological necrosis of femoral head tissue. If not treated in time in clinical practice, it will seriously affect the quality of life of patients and even require hip replacement to treat alcoholic femoral head necrosis. This study will confirm whether M2 macrophage exosome (M2-Exo) miR-122 mediates alcohol-induced BMSCs osteogenic differentiation, ultimately leading to the inhibition of femoral head necrosis.

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: Aim of the present paper is to report the preliminary results of CAD-CAM (Computer-Aided Design - Computer-Aided Manufacturing) technology application to distal femur nonunion treatment with free fibula flap, custom made medial plating and maintenance of a stable lateral locking plate.
Methods: Two cases of distal femur nonunion that occurred after lateral locking plating were treated and prospectively followed-up. Surgical planning followed the same preoperative protocol adopted for mandibular CAD-CAM reconstruction.
