We present the case of a 60-year-old man who had metastasis of a nodular squamous cell carcinoma from a laryngeal carcinoma that mimicked an infected sinus in a 4-month postoperative revision total hip arthroplasty scar. A diagnosis was made at the time of frozen section. The patient died 3 months after tumor resection as a result of multiorgan failure. Nodular squamous cell carcinoma metastasis in a total hip arthroplasty scar is extremely uncommon. However, this association must be considered in a patient with a known tumor after revision surgery. In such patients, we recommend obtaining an intraoperative frozen section to avoid misdiagnosis in cases of infected sinuses associated with implants.

Povidone-Iodine Versus Saline Irrigation on Reduction of Surgical Site Infections in Total Hip and Knee Arthroplasty: A Retrospective, Propensity-Matched Cohort.

Surgical site infection (SSI) after total hip and knee arthroplasty (THA/TKA) is a major complication leading to morbidity and mortality. Perioperative irrigation, frequently with antiseptic compounds including povidone-iodine (PI), is the standard of care in reducing SSI. Evidence supporting the value of PI versus nonantiseptic substances varies.

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.

Department of Orthopedics, West China Hospital, Sichuan University, Chengdu, Sichuan, China.
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).

Recurrent groin pain following periacetabular osteotomy (PAO) is a challenging problem. The purpose of our study was to evaluate the position and dynamics of the psoas tendon as a potential cause for recurrent groin pain following PAO. A total of 386 PAO procedures, performed between January 2013 and January 2020, were identified from a single surgeon series.

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.
