Background: Despite advancements, THA is still associated with risks, particularly venous thromboembolism (VTE). THA in patients with high-riding developmental dysplasia of the hip (DDH) could potentially be associated with an elevated risk of VTE. We conducted a study to evaluate whether patients with high-riding DDH undergoing THA and receiving aspirin have an increased risk of symptomatic VTE compared with patients undergoing primary THA for other diagnoses.

Background: The coincidence rate of femoroacetabular impingement (FAI) or acetabular retroversion (AR) with anterior ankle impingement (AAI) is not known. In this preliminary study, we investigated the coexistence of FAI and AR in a cohort of patients presented with AAI.

Methods: In a cross-sectional study, 56 patients who presented with AAI and underwent arthroscopic surgery for AAI treatment were included.

Background: The best stem type and location for femoral shortening in high-riding developmental dysplasia of the hip (DDH) in not clear. We evaluated the morphology of the proximal femur on EOS™ images, focusing on the anatomical landmarks and measurements relevant to the stem selection in high-riding DDH. Our goal is to identify and define the differences in the anatomy of the proximal femur between patients with Crowe type IV DDH and normal individuals, in order to determine the appropriate neck cut location in these patients to increase the chances of successfully using a wedge femoral stem.

Article Synopsis
  • The text discusses challenges in performing total hip arthroplasty (THA) for patients with severe hip dysplasia (Crowe Type IV DDH), highlighting two surgical techniques: subtrochanteric shortening osteotomy and trochanteric slide osteotomy.
  • The study aims to determine if there are differences in clinical outcomes (Harris Hip Score and limb length discrepancies) and complication rates between these two methods after at least three years of follow-up.
  • A total of 67 surgeries were analyzed, with 42% using subtrochanteric shortening osteotomy and 58% using trochanteric slide osteotomy; data was matched for sex and preoperative scores to focus

Background: Deferoxamine (DFO) angiogenesis induction potential has been demonstrated in earlier studies, but not in the osteonecrosis of the femoral head (ONFH). In this study, we evaluated the outcome of ONFH treated with combined core decompression and local DFO administration loaded on Polylactic Glycolic Acid (PLGA).

Patients And Methods: In a pilot experimental study, six patients (10 hips) with early-stage non-traumatic ONFH were treated by core decompression, and concurrent injection of local DFO loaded on PLGA scaffold into the subchondral femoral head.

Background: Long-term Bisphosphonate consumption has been reported to be associated with the incidence of atypical or insufficiency fracture, particularly in the proximal femur. We observed a case of acetabular and sacral insufficiency fractures in a patient with a long-term history of Alendronate consumption.

Case Presentation: A 62-year-old woman was admitted with a complaint of pain in right lower limb following low-energy trauma.

Background: THA for high-riding developmental dysplasia of the hip (DDH) is challenging in terms of length equalization. Although previous studies suggested preoperative templating on AP pelvic radiographs is insufficient in patients with unilateral high-riding DDH because of hypoplasia of the hemipelvis on the affected side and unequal femoral and tibial length on scanograms, the results were controversial. The EOS™ (EOS™ Imaging) is a biplane X-ray imaging system using slot-scanning technology.

Background: The impact of periarticular corticosteroid injection for pain control after total joint arthroplasty (TJA) is controversial. The present study aimed to investigate this controversy in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods: A total of 42 THA and 42 TKA patients were included in this study.

Background: The purpose of this study is to describe the midterm clinical and radiologic outcomes of concurrent femoral head reduction osteotomy (FHRO) and periacetabular osteotomy (PAO) in Legg-Calvé-Perthes disease (LCPD) patients with major aspherical femoral head deformities.

Methods: The study included four Perthes patients in Stage IV of Waldenstrom's classification with a mean age of 10.5 and severe femoral head asphericity.

Background: Addressing acetabular deficiency during arthroplasty of dysplastic hips is challenging. We assessed outcomes of a protocol for choosing either impaction or structural graft for this purpose.

Methods: This retrospective study included 59 patients (71 hips) with a dysplastic hip and over 30% uncoverage that underwent cementless total hip arthroplasty.

Background: Femoral head osteonecrosis is a progressive disease with disabling outcomes in hip joint if not treated. This study was designed to compare the effects of zoledronic acid plus vitamin E versus zoledronic acid alone in surgical induced femoral head osteonecrosis in rabbits.

Methods: 26 Japanese white adult normal male rabbits at 28-32 weeks old were undertaken surgical femoral dislocation to devastate the femoral neck vessels; the femoral neck vessels were ligated and the hip was relocated.

Background: Postpartum bilateral femoral neck fracture (BFNF) is a rare condition. We here report a case of BFNF due to excessive corticosteroid consumption, twin pregnancy, immobility, and vitamin D deficiency.

Case: This is a report of a 32-yr-old woman with bilateral femoral insufficiency fracture five days after emergency cesarean section due to preterm labor, twin pregnancy, and the history of a previous cesarean section at 33 wk.

Objectives: The purpose of this study was to report (1) a different but specific pattern of impingement in hips involved with valgus slipped capital femoral epiphysis (valgus SCFE) and (2) the results of surgical treatment using intracapsular realignment techniques.

Design: Case series.

Setting: Multiple academic centers.

Purpose: Femoroacetabular impingement may be associated with anterior cruciate ligament (ACL) injuries. The purpose of this study was to determine the head-neck offset, as measured by 45° Dunn's view alpha angles, in patients with ACL injuries compared to control subjects.

Methods: In this retrospective study, 140 consecutive non-professional athletes with primary ACL ruptures confirmed with knee arthroscopy and 100 consecutive patients with non-ACL injury were enrolled.

Habitual dislocation of the hip (HDH) in children is a rare entity and can be a causative factor for popping or snapping hip which is a common problem in children with good prognosis. We report a case of HDH in a 9 year old girl who was suffering from frequent snapping hip at night, its course and treatment process.

Background: Both synovial chondromatosis and femoroacetabular impingement present with hip pain and may lead to hip osteoarthritis. We present a small case series and describe the clinical presentation, investigation, and treatment of patients with synovial chondromatosis who also had cam-type femoroacetabular impingement involving the same hip.

Methods: Five patients (four men and one woman with a mean age of thirty-four years [range, thirty to thirty-seven years]) with unilateral synovial chondromatosis of the hip presented with clinical and radiographic features of ipsilateral cam-type femoroacetabular impingement.
