Introduction This study evaluated hip joint dynamic instability in patients with non-traumatic osteonecrosis of the femoral head (ONFH) with extensive lesions, who had undergone anterior rotational osteotomy (ARO) and high-degree posterior rotational osteotomy (HDPRO), based on the femoral head translation observed by computed tomography (CT) at 0° and 45° hip flexion. Materials and methods Medical records of patients who had undergone transtrochanteric rotational osteotomy for non-traumatic ONFH were retrospectively reviewed to identify patients who had undergone CT examinations six weeks post-operatively. In all, 64 hips (60 patients; 19 men and 41 women), comprising 36 hips treated with HDPRO and 28 hips treated with ARO, respectively, were included.

Background: Curved varus osteotomy (CVO) is an effective femoral head-preserving surgical procedure for osteonecrosis of the femoral head (ONFH) classified as type B or C1 according to the Japanese Investigation Committee (JIC) classification; it reportedly provides better postoperative outcomes than transtrochanteric rotational osteotomy (TRO). We have developed a new procedure called spherical varus rotational osteotomy (SVRO) in which osteotomy of the femur into a spherical shape is followed by varus and anterior rotation using navigation to increase indications and improve postoperative outcomes.
Methods: Nine joints of eight patients who underwent SVRO and could be followed up for > 1 year were included in the study.

Objective: To describe and analyze the aspects regarding the cost and length of stay for elderly patients with bone fractures in a tertiary reference hospital.
Methods: A cross-sectional retrospective study using data obtained from medical records between January and December 2020. For statistical analysis, exploratory analyses, Shapiro-Wilk test, χ2 test, and Spearman correlation were used.

Several preservative treatment options are available for the early stages of avascular necrosis of the femoral head (ANFH) but are not as effective as in the advanced-stages. The management of Ficat stage III-IV AFNH is limited to the high rate of patients being converted to total hip replacement (THR). Four female patients with Ficat stage III-IV ANFH were included in this study, with a median age of 32.

Purpose: This study retrospectively evaluated long-term clinical outcomes and patient-reported outcome measures (PROMs) in patients with osteonecrosis of the femoral head (ONFH) who underwent transtrochanteric rotational osteotomy (TRO), curved varus osteotomy (CVO), and total hip arthroplasty (THA).
Methods: We retrospectively reviewed the 109 hips in 96 patients (46 men, 50 women) who underwent CVO, TRO, or THA for ONFH treatment. The mean follow-up period for the TRO, CVO, and THA groups was 14.
