Purpose: Many studies have been conducted to evaluate the effects of nail shape, design, or length on the treatment of intertrochanteric fractures. However, the clinical implications of the nail diameter remain unclear.

Methods: This study was conducted with 191 patients aged ≥ 50 years with unilateral intertrochanteric fractures treated with the same type of short cephalomedullary nail and followed for at least one year.

The aim of this study was to assess injury patterns and risk factors of the acetabular labrum and associated cartilage in patients with femoroacetabular impingement (FAI) versus dysplasia. We retrospectively reviewed 137 patients diagnosed with labral tears and FAI or dysplasia (74 or 63 cases, respectively) through an arthroscopic procedure. Labral and concomitant cartilage injuries were evaluated.

Background: Studies explaining the relationship between hip and spine reported that spinal corrective surgery affected acetabular orientation and changes in pelvic tilt were capable of influencing radiographic measures of acetabular coverage. This study aimed to assess the change in coronal parameters for acetabular coverage as a result of adult spinal deformity (ASD) correction and to analyze the relationship between the postoperative changes in sagittal spinopelvic parameters and coronal acetabular coverage parameters.

Methods: Fifty-two consecutive patients who had undergone multilevel spinal surgical correction were enrolled and evaluated.

Article Synopsis
  • The study introduces percutaneous elastic intramedullary nailing (PEIN) as a treatment method for symptomatic incomplete atypical femoral fractures (SIAFF).
  • It involved treating 6 patients from October 2014 to April 2019, assessing factors like operating time, callus formation, and any complications.
  • Results showed PEIN is a quick and effective option, with most cases showing successful fracture healing and minimal complications, even in patients with significant femoral bowing.

Unlabelled: There still remains controversy on the pathomechanism of atypical femoral fracture (AFF). The angle of lateral bowing and bone mineral density showed significant differences between subtrochanteric and diaphyseal atypical fracture groups. In addition to the use of bisphosphonate, mechanical factors might play important roles in the occurrence of AFFs.

Atypical insufficiency fracture of the femur following prolonged bisphosphonate use is well described. Regardless of the cause, insufficiency fracture of the acetabulum is extremely rare, and no reports have described insufficiency fractures of the acetabulum that are associated with prolonged bisphosphonate use. This report demonstrates the possibility of insufficiency fracture at the acetabulum following long-term alendronate use and the necessity of particular care in managing insufficiency fractures in "frozen" bone.

Background: We intended to clarify the hypothesis that minimally invasive total hip arthroplasty (MI-THA) leads to less tissue damage and inflammatory response than does conventional total hip arthroplasty (C-THA).

Methods: We performed 30 cases of THA between September 2005 and May 2006 and evaluated these cases prospectively. We chose 15 MI-THA cases for the study group and another 15 C-THA cases for the control group.

Purpose: The purpose of this study was to investigate the effect of diabetes mellitus on primary total hip arthroplasty by comparing the clinical outcomes of patients diagnosed to have diabetes mellitus before the operation with those without diabetes.

Materials And Methods: A total 413 patients who underwent unilateral cementless total hip arthroplasty from June 2006 to May 2009 were recruited and divided into diabetic and non-diabetic groups. The comparative analysis between the two groups was made.

Article Synopsis
  • A case report presented a successful series of spinal osteotomies on a patient with severe kyphotic deformity due to ankylosing spondylitis.
  • The 48-year-old male patient had a significant "chin-on-pubis" deformity and underwent multiple surgical interventions, including hip arthroplasties and spinal osteotomies in various regions of the spine.
  • Results showed significant improvement in spinal alignment and daily living activities, achieving remarkable correction angles without complications, marking a pioneering approach in this type of surgery.
