Introduction: Traumatic dislocation of the hip with ipsilateral fracture neck femur is a rare injury because of the different mechanism of both these injuries. The management of such injuries is a challenge as the chances of nonunion and avascular necrosis of femoral head are very high with fixation methods. We report a case of obturator dislocation of the hip with ipsilateral fracture neck of the femur which was treated with uncemented total hip replacement. Case Report: A 32-year-old male sustained obturator dislocation with ipsilateral fracture neck femur following road traffic accident...

Metastatic spinal cord compression (MSCC) is a medical emergency that requires rapid diagnosis and treatment to reduce pain, to preserve neurological functioning, and to prolong survival. The diagnosis of liver cancer is often neglected in the differential diagnosis of MSCC. Treatment is usually palliative and evolution is often fatal. This is a case report of a 28-year-old patient living in Mauritania hospitalized in November 2014 at the neurology department of Fann national teaching hospital in Dakar, for the management of a chronic dorsal spinal cord compression...

Background: Hip arthroscopic surgery is intended to treat multiple abnormalities in an effort to delay the progression to osteoarthritis, especially in young patients. However, the length of time in which patients experience joint pain before seeking a specialist for a diagnosis can delay hip preservation surgery and influence clinical outcomes. Purpose: To investigate the relationship between age at symptom onset and findings during hip arthroscopic surgery as well as outcomes after 2 years of clinical follow-up...

Background: Preoperative total hip arthroplasty templating can be performed with radiographs using acetate prints, digital viewing software, or with computed tomography (CT) images. Our hypothesis is that 3D templating is more precise and accurate with cup size prediction as compared to 2D templating with acetate prints and digital templating software. Methods: Data collected from 45 patients undergoing robotic-assisted total hip arthroplasty compared cup sizes templated on acetate prints and OrthoView software to MAKOplasty software that uses CT scan...

Removing well-fixed acetabular components can be a challenge for orthopaedic surgeons in revision of total hip arthroplasty. Acetabular bone loss, fracture, and other complications occurred in extracting implants may result in instability and fail of revision. Thus, instruments are developed to avoid such complications. We report a simple technique by drilling a tunnel on the superolateral quadrant of acetabulum and using an offset staff to remove acetabular components without many matching units. The procedure of removing well-fixed acetabular components is a simple, efficient, inexpensive, bone stock preserving technique...

The purpose of this study is to investigate the compensatory correlation between knee and hindfoot in patients with rheumatoid arthritis (RA). This cross-sectional study included 218 patients (407 lower extremities). Radiographs of the hindfoot and full-length posteroanterior hip-to-calcaneus standing radiographs were evaluated. The destruction of the hindfoot was evaluated using the Larsen grading system. The coronal angular deformity of the knee and hindfoot was evaluated by the femorotibial angle (FTA) and the angle between the tibial shaft and the entire hindfoot (tibiohindfoot angle, THFA)...

The poor results obtained in young patients when using a conventional prosthesis led to the resurgence of hip resurfacing to find less invasive implants for the bone. Young patients present a demand for additional activity, which makes them a serious challenge for the survival of implants. In addition, new information technologies contribute decisively to the preference for non-cemented prostheses. Maintaining quality of life, preserving the bone and soft tissues, as well as achieving a very stable implant, are the goals of every hip orthopaedic surgeon for these patients...

INTRODUCTION: The non-arthroplasty hip registry (NAHR) is a United Kingdom national register that monitors the efficacy of hip preservation surgery. We aim to highlight early experiences of incorporating the NAHR into our practice at a tertiary centre. METHODS: Between December 2013 and February 2015, 381 patients were identified on the NAHR database that had undergone non-arthroplasty hip surgery. Patient-related outcome measures EuroQuol 5D-5L (EQ-5D) and the International Hip Outcome Tool 12 (iHOT-12) were recorded at baseline and 6 months...

BACKGROUND/AIM: Scattered radiation during radiotherapy (RT) directed at the hip joint poses concerns about ovarian function in patients of reproductive age. Here, we report the impact of using a split-beam technique (SBT) and different photon energies on the total ovary dose during radiation prophylaxis of heterotopic ossification (HO). PATIENTS AND METHODS: This was a single-institution, retrospective study of 32-patients with traumatic acetabular fractures (TAF)...

BACKGROUND: Surgical dislocation of the hip remains an important alternative in hip preservation surgery, especially when a dynamic access to the hip is needed and arthroscopy is not a suitable option. We describe a novel technique for operative dislocation of the hip without trochanteric osteotomy and the clinical results of our patients. METHODS: Surgical dislocation of the hip without trochanteric osteotomy was done through a modified lateral approach in all of the cases...

BACKGROUND: Impingement ensures a narrow arc of pathologic loading in adolescent hips with sequelae of Perthes Disease. Proper surgical interference when the hip is still in the pre-arthritic stage restores function and protects the young hip from early degenerative changes. METHODS: Osteochondroplasty at the femoral head-neck junction and relative lengthening of the femoral neck by distal transfer of the greater trochanter was performed for 12 adolescents with combined intra-articular/extra-articular impingement due to sequelae of Perthes disease in terms of coxa magna, coxa plana, coxa brevis, with an overriding greater trochanter...

PURPOSE: Short-stem hip arthroplasty (SHA) was designed to preserve bone stock and provide an improved load transfer. To gain more evidence regarding the load transfer, this review analysed the periprosthetic bone remodelling of SHA in comparison to standard hip arthroplasty (THA). METHODS: PubMed and ScienceDirect were screened to extract dual-energy X-ray absorptiometry (DXA) studies evaluating the periprosthetic bone remodelling of SHA and two proven THA designs...

Vimal Chandran, Mauricio Reyes, Philippe Zysset
Osteoporosis leads to hip fractures in aging populations and is diagnosed by modern medical imaging techniques such as quantitative computed tomography (QCT). Hip fracture sites involve trabecular bone, whose strength is determined by volume fraction and orientation, known as fabric. However, bone fabric cannot be reliably assessed in clinical QCT images of proximal femur. Accordingly, we propose a novel registration-based estimation of bone fabric designed to preserve tensor properties of bone fabric and to map bone fabric by a global and local decomposition of the gradient of a non-rigid image registration transformation...

To establish the pattern of bone remodeling caused by a cementless, anatomic implant, we intend to evaluate the changes in bone mineral density observed after surgery in the Gruen zones. A controlled, prospective study was carried out, in which a group of 37 patients with primary coxarthrosis were densitrometrically analyzed over the 1 year period following the implant of an ANATO stem (Stryker). The patient's healthy hip was taken as the control. Any differences in the remodeling pattern were compared according to age, body mass index, and implant size...

BACKGROUND: "Advanced Core Decompression" (ACD) is a new technique for treatment of osteonecrosis of the femoral head (ONFH) that includes removal of the necrotic tissue using a percutaneous expandable reamer followed by refilling of the drill hole and the defect with an injectable, hard-setting, composite calcium sulphate (CaSO4)-calcium phosphate (CaPO4) bone graft substitute. As autologous bone has been shown to be superior to all other types of bone grafts, the aim of the study is to present and evaluate a modified technique of ACD with impaction of autologous bone derived from the femoral neck into the necrotic defect...

Mark Ruddy, David P FitzPatrick, Kenneth T Stanton
Impaction bone grafting is a method of restoring bone stock to patients suffering significant bone loss due to revision total hip surgery. The procedure requires morselised bone (MB) to be impacted into the site of bone loss in order to stabilise the prosthesis with the aim of the long term resorption and reintegration of the impacted bone graft. Currently, the method for producing MB requires the use of expensive surgical bone mills or manually-intensive rongeurs that can produce a limited variety of particle sizes and may have a low throughput...

BACKGROUND: Laxity of soft tissues after total hip arthroplasty is considered to be a cause of accelerated wear of bearing surfaces and dislocation. The purpose of this study is to assess the contribution of the anterior and posterior capsular ligamentous complexes and the short external rotators, except the quadratus femoris, on the stability of the hip against axial traction. METHODS: The study subjects comprised 7 fresh cadavers with 12 normal hip joints. In 6 hips, soft tissues surrounding the hip joint were resected in the following order to simulate the anterior approach: anterior capsule, posterior capsule, piriformis, conjoined tendon, and external obturator...
