Structural deformities of the acetabulum secondary to developmental dysplasia of the hip (DDH) are one of the most common causes requiring total hip arthroplasty (THA), whether in conjunction with femoral osteotomy in cases of Crowe dislocation 4. Several techniques have been described, studied, and compared, but there is no superiority of one technique over another. Currently, most hip surgeons perform a subtrochanteric osteotomy. With a follow-up of 10 years, good results have been obtained, so there is a need to present a therapeutic alternative with potential benefits, mainly in restoring the center of rotation of the hip, preserving the proximal bone component, and reducing complications. Therefore, this study aims to describe the surgical technique of CTA in conjunction with supracondylar shortening osteotomy in a 29-year-old female patient, using an uncemented acetabular cup, a short uncemented stem with ceramic-polyethylene bearing, and distal fixation with a 4-hole plate LC-LCP, with the goal of restoring the natural biomechanics of the hip.

Surgical options for Evans-Jensen type IV intertrochanteric femur fractures in the elderly over 65: a comparison between total hip arthroplasty and proximal femoral nail antirotation.

Background: Currently, there is no clear standard for the surgical options for Evans-Jensen Type IV intertrochanteric femur fractures in elderly patients over 65 years old. This study aims to retrospectively analyze and compare the early postoperative limb function and quality of life of patients treated with total hip arthroplasty (THA) and proximal femoral nail antirotation (PFNA) for this type of fracture. We hypothesize that there is no significant difference in complications and postoperative recovery between the two surgical methods.

Background: The debate continues on whether combining core decompression (CD) with regenerative therapy provides a more effective treatment for early femoral head necrosis than CD alone. This systematic review and meta-analysis endeavored to assess its efficacy.
Methods: We systematically searched PubMed, Web of Science, and Cochrane Library through July 2024 for RCTs and cohort studies evaluating the impact of core decompression (CD) with regenerative therapy versus CD alone in early-stage osteonecrosis (ARCO I, II or IIIa or Ficat I or II) of the femoral head (ONFH).

Osteonecrosis of femoral head (ONFH) can be a debilitating disease, for which numerous salvage surgeries have been popularized to halt its progression. The aim of this study was to assess the clinical and radiological outcomes of a single-incision core decompression (CD) technique using trochanteric autograft in ONFH and to determine the prognostic factors of treatment success. Sixty-six hips (41 patients) of Association Research Circulation (ARCO) 1 and 2 ONFH undergoing CD were included in the study with a mean follow-up of 58 months.

The aim of this article is to determine the safety and efficacy of core decompression (CD) combined with injection of autologous bone marrow concentrate (BMC), demineralized bone matrix (DBM), and platelet-rich fibrin (PRF) for treating femoral head osteonecrosis. Seventy-seven patients (53 males and 24 females) for a total of 87 hips were treated for hip osteonecrosis with CD combined with injection of autologous BMC, DBM, and PRF at Rizzoli Orthopedic Institute from September 2008 to December 2019. Patients were assessed at baseline, at 45 days, and at 3, 6, 12, 24, and 36 months postoperatively.

Purpose: Tranexamic acid is widely accepted for hip fractures but there is no agreement about dose or application method and the use is still off label for hip fractures. The aim of our study was to find the best application method of tranexamic acid in patients with femoral neck fractures comparing total blood loss, hemoglobin and transfusion rate.
Methods: A retrospective single centre cohort study (level I trauma centre) with 2008 patients treated operatively for a proximal femur fracture between January 2016 and January 2022 was performed.
