Acetabular fracture is usually treated with osteosynthesis. However, in the case of an intra-articular fracture, osteosynthesis can result in arthropathy of the hip joint and poor long-term results, hence, total hip arthroplasty is required. However, in total hip arthroplasty for postoperative acetabular fracture, sciatic nerve palsy tends to develop more commonly than after primary total hip arthroplasty. This is a case report of a 57-year-old Japanese male who had internal skeletal fixation for a left acetabular fracture that had occurred 2 years earlier...

Background and purpose - The length of stay after total hip arthroplasty has been reduced to 2-4 days after implementing fast-track surgery. We investigated whether a new time-based patient-centered primary direct anterior approach (DAA) total hip arthroplasty (THA) treatment protocol in a specialized clinic, with a planned length of stay of about 24 hours, could be achieved in all patients or only in a selected group of patients. Patients and methods - We analyzed prospectively collected data in a cohort of 378 consecutive patients who underwent a primary direct anterior THA as a patient-centered time-based procedure between March 1, 2012 and December 31, 2015...

BACKGROUND: Avascular necrosis of the femoral head (AVN) is the most serious complication after unstable slipped capital femoral epiphysis (SCFE), and is often unsalvageable. We report a minimum 10 years of clinical results for transtrochanteric rotational osteotomy of the femoral head (TRO) for AVN. METHODS: This study included 7 patients (7 hips) with a mean age at surgery of 13.3 years, and the follow-up period was 15.8 years. All patients had prior treatment via closed reduction and pinning of the unstable SCFE, and showed severely collapsed femoral heads...

Introduction: There have been significant increases in the number of acetabular fractures in elderly patients with primarily ventral pathology and medial protrusion of the femoral head. We have developed the "acetabulum wing plate", which is designed to facilitate repositioning, with its anatomically precontoured structure, and which offers full support of the quadrilateral surface, thus counteracting the force of the femoral head pushing inwards. Conventional plate osteosynthesis only provides insufficient support to the medial surface...

INTRODUCTION: Chances of avascular necrosis of acetabulum are rare as it enjoys a rich blood supply. But cases of post - traumatic avascular necrosis of acetabulum following fracture of posterior column have been well documented. Importance of identifying and suspecting the avascular necrosis of acetabulum is essential in cases of failed fixation of fracture acetabulum, previously operated using extensile approach to acetabulum; either extended anterior ilio - femoral or tri - radiate approach...

INTRODUCTION: Anterior dislocation of hip associated with fracture of proximal femur is an uncommon injury. Only very few cases are reported in the literature. We report such an unusual and previously not described case of anterior dislocation of hip associated with fracture of trochanter and neck of the femur in an elderly lady. CASE REPORT: A 60 year old lady was presented to our casualty following a fall at home. She complained of pain in the left hip with deformity and inability to move the limb...

BACKGROUND: With the evolution of total hip joint replacement techniques, there has been a trend towards minimally invasive surgery. The anterior approach (AA) to total hip arthroplasty has been widely associated with less soft tissue damage. The aim of our study was to compare clinical and 1-year functional outcomes for AA hip arthroplasty versus a posterior approach (PA). METHOD: We retrospectively reviewed 92 (50 anterior and 42 posterior) total hip replacements performed at our centre between 2006 and 2011...

BACKGROUND: Many labral tears are nonrepairable. For these cases, labral reconstruction procedures may be considered in order to restore the joint fluid seal and prolong hip longevity. AIMS: The aim of this study was to describe the clinical and functional outcomes of a series of cases with nonrepairable labral tears that underwent labral reconstruction with tendon allografts. The hypothesis was that labral reconstruction would provide good clinical outcomes. METHOD: A cohort of 20 patients with nonrepairable labral tears, which underwent to labral grafting mainly by means of arthroscopic assisted anterior mini-open approach, were included in this study...

OBJECTIVE Heterotopic ossification (HO) has been reported following total hip, knee, cervical, and lumbar arthroplasty, as well as following posterolateral lumbar fusion using recombinant human bone morphogenetic protein-2 (rhBMP-2). Data regarding HO following anterior cervical discectomy and fusion (ACDF) with rhBMP-2 are sparse. A subanalysis was done of the prospective, multicenter, investigational device exemption trial that compared rhBMP-2 on an absorbable collagen sponge (ACS) versus allograft in ACDF for patients with symptomatic single-level cervical degenerative disc disease...

BACKGROUND: The direct anterior approach (DAA) for total hip arthroplasty (THA) has rapidly become popular, but there is little consensus regarding the risks and benefits of this approach in comparison with a modern posterior approach (PA). METHODS: A total of 2147 patients who underwent DAA THA were propensity score matched with patients undergoing PA THA on the basis of age, gender, body mass index, and American Society of Anesthesia classification using data from a state joint replacement registry...

Several approaches may be used for hip replacement surgery either in combination with conventional total hip arthroplasty (THA) or resurfacing hip arthroplasty (RHA). This study investigates the differences in hip loading during gait one year or more after surgery in three cohorts presenting different surgical procedures, more specific RHA placed using the direct lateral (RHA-DLA, n=8) and posterolateral (RHA-PLA, n=14) approach as well as THA placed using the direct anterior (THA-DAA, n=12) approach. For the DAA and control subjects, hip loading was also evaluated during stair ascent and descent to evaluate whether these motions can better discriminate between patients and controls compared to gait...

OBJECTIVE Beginning in 2008, the Centers for Medicare and Medicaid Service (CMS) determined that certain hospital-acquired adverse events such as surgical site infection (SSI) following spine surgery should never occur. The following year, they expanded the ruling to include deep vein thrombosis (DVT) and pulmonary embolism (PE) following total joint arthroplasty. Due to their ruling that "never events" are not the payers' responsibility, CMS insists that the costs of managing these complications be borne by hospitals and health care providers, rather than billings to health care payers for additional care required in their management...

BACKGROUND: Retractor placement is a leading cause of intraoperative nerve injury during total hip replacement (THR) surgery. The sciatic nerve, femoral nerve, and superior gluteal nerve are most commonly affected. This study aimed to identify the distances from bony landmarks in the hip to the adjacent nerves on magnetic resonance imaging (MRI) and the associations between anatomical factors and these distances that would guide the placement of retractors during THR surgery, in order to minimize the risk of nerve injury...
