Results: The activities conducted on-site in the Noto Peninsula involved multiple deployments of the Juntendo University Shizuoka Hospital Disaster Medical Assistance Team (JS-DMAT).

Total hip arthroplasty with subtrochanteric femoral shortening osteotomy using a monoblock cylindrical cementless stem for severe developmental hip dysplasia (Crowe type III, IV).

Background: Treatment of patients with Crowe type III and IV dislocated hips is challenging because of the hip deformity in these patients. In addition to the usual total hip replacement, shortening and reduction of the femur are often required. We herein report on our surgical technique using a monoblock cylindrical cementless stem and a direct lateral approach.

Use of a Helicopter Emergency Medical Service Hangar as a Staging Care Unit in a Disaster-Affected Area.

Objective: There are a few reports regarding the use of a hangar as a temporal medical facility (staging care unit [SCU]) during large-scale disasters. The aim of this study was to describe the activities performed by disaster medical assistance teams (DMATs) at the hangar of the eastern Shizuoka physician-staffed helicopter as an SCU in the 2022 Shizuoka Prefecture disaster drill.

Methods: We selected the narrative method for this study.

Paradoxical Embolization of the Bilateral Subclavian Arteries After High Tibial Osteotomy.

A patent foramen ovale provides a portal through which a thrombus might pass from the right side of the circulation to the left. A 65-year-old man underwent high tibial osteotomy after the diagnosis of the right knee osteoarthritis. On postoperative day 12, he developed bilateral arm paresthesia.

Total hip arthroplasty for a woman with hemophilia A -case report.

Hemophilia A is a congenital bleeding disorder caused by an X-linked hereditary pattern. Female hemophilia A carriers are usually asymptomatic, although some have far lower levels of clotting factor because more X chromosomes with the normal gene are switched off, a phenomenon referred to as "lyonization." During a medical checkup at our hospital, a 56-year-old Japanese woman with coxalgia was also diagnosed as an obligate hemophilia A carrier based on World Federation of Hemophilia criteria.

Preservation of the articular capsule and short lateral rotator in direct anterior approach to total hip arthroplasty.

Introduction: In total hip arthroplasty via a direct anterior approach, the femur must be elevated at the time of femoral implant placement. For adequate elevation, division of the posterior soft tissues is necessary. However, if we damage and separate the posterior muscle tissue, we lose the benefits of the intermuscular approach.

"Within ring"-based sacroiliac rod fixation may overcome the weakness of spinopelvic fixation for unstable pelvic ring injuries: technical notes and clinical outcomes.

Purpose: Spinopelvic fixation and triangular osteosynthesis give firm internal fixation for unstable pelvic ring injuries (UPRI), but with sacrifice of mobility of the lumbar spine. Here, we describe the procedure and outcomes of a new approach, which we refer to as "within ring"-based sacroiliac rod fixation (SIRF).

Methods: The patient was placed in a prone position and longitudinal skin incisions were made at the medial margins of the bilateral posterior superior iliac spines (PSIS).

A study of the blood flow restriction pressure of a tourniquet system to facilitate development of a system that can prevent musculoskeletal complications.

Background: After an emergency or disaster, subsequent trauma can cause severe bleeding and this can often prove fatal, so promptly stopping that bleeding is crucial to preventing avoidable trauma deaths. A tourniquet is often used to restrict blood flow to an extremity. In operation and hospital, the tourniquet systems currently in use are pneumatically actuated by an air compressor, so they must have a steady power supply.

Intraoperative dislocation of the trial bipolar cup into the pelvis during bipolar hip arthroplasty - A case report.

Introduction: Bipolar hip arthroplasty is a good option for treating femoral neck fractures, although some contraindications have been indicated. We report a case of intraoperative dislocation of the trial bipolar cup into the pelvis during bipolar hip arthroplasty.

Case Presentation: A 74-year-old woman underwent bipolar hip arthroplasty for a femoral neck fracture (AO31-B2).

Malreduction of syndesmosis injury associated with malleolar ankle fracture can be avoided using Weber's three indexes in the mortise view.

Purpose: Malalignment of syndesmosis is generally associated with a poor outcome, yet occurs at a high rate in malleolar ankle fractures. In this study, we examine whether malreduction of syndesmosis injury associated with malleolar ankle fracture can be avoided using Weber's three indexes in the mortise view.

Materials And Methods: Of 156 patients with malleolar ankle fracture who underwent surgery from December 2012 to March 2016 at two medical facilities, 24 patients who received syndesmotic screw fixation were included in the study.

Acoustic pattern evaluation during cementless hip arthroplasty surgery may be a new method for predicting complications.

Background: Although surgeons must perform implantation of the cementless stem during total hip arthroplasty (THA) without complications, assessment is left to the surgeon's intuitive judgement, which could contain inter/intra-observer bias variety. We therefore asked (1) whether the sound created during the stem implantation could be evaluated objectively and (2) whether those sounds are correlate to the complication specific to the cementless stems. Our hypothesis is that the sounds produced during stem insertion could be quantified and related to the complications.

Treatment of postoperative sciatic nerve palsy after total hip arthroplasty for postoperative acetabular fracture: A case report.

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.

New classification focusing on the relationship between the attachment of the iliofemoral ligament and the course of the fracture line for intertrochanteric fractures.

Purpose: There are various types of intertrochanteric fractures that are unstable pertrochanteric fractures of the hip. The aim of this study was to develop a systematic and comprehensive classification of intertrochanteric fractures.

Materials And Methods: This study enrolled 74 patients with intertrochanteric fractures treated by us between 2012 and 2015.

Total Hip Arthroplasty Using a Polished Tapered Cemented Stem in Hereditary Multiple Exostosis.

A 61-year-old Japanese man underwent right total hip arthroplasty for hereditary multiple exostosis. At first presentation, he had suffered from coxalgia for a long time. On radiographic images, there was a gigantic femoral head, increased shaft angle, and large diameter of the femoral neck.

Iliopsoas impingement after revision total hip arthroplasty treated with iliopsoas muscle transection.

Introduction: Iliopsoas tendinitis after revision total hip arthroplasty (THA) is rare and its etiology and optimal treatment are still unclear. We report a case of iliopsoas impingement after revision THA with a Kerboull acetabular reinforcement device requiring two-level iliopsoas muscle transection.

Presentation Of Case: A 70-year-old woman presented to our hospital complaining of debilitating right groin pain after revision THA with a Kerboull reinforcement device.

A 42-year-old patient presenting with femoral head migration after hemiarthroplasty performed 22 years earlier: a case report.

Introduction: Treatment of femoral neck fractures in young adults may require total hip arthroplasty or hip hemiarthroplasty using a bipolar cup. The latter can, however, result in migration of the femoral head and poor long-term results.

Case Presentation: We report a case of femoral head migration after hemiarthroplasty performed for femoral neck fracture that had occurred 22 years earlier, when the patient (a Japanese man) was 20 years old.

Introduction of a physician-staffed helicopter emergency medical service in eastern Shizuoka prefecture in Japan.

Objective: To analyze the operating situation of a physician-staffed helicopter emergency medical service in eastern Shizuoka prefecture.

Methods: A retrospective analysis was performed using the conveyance records reported by staff members of the physician-staffed helicopter. A comparison between 2007 (n = 619) and 2012 (n = 678) was performed.

New classification focusing on implant designs useful for setting therapeutic strategy for periprosthetic femoral fractures.

Purpose: In periprosthetic femoral fractures, our hypothesis was that when the bone and implant are stable, the fracture does not occur at the biologic or cement fixation regions but occurs at the no fixation region. The aim of this study was to investigate the validity of our new classification for periprosthetic femoral fractures and compare reliability of radiographic evaluation for implant stability between our classification and the Vancouver classification.

Patients And Methods: Sixty-six patients with periprosthetic femoral fracture were operatively treated by us between 2005 and 2013.

The Massive Bleeding after the Operation of Hip Joint Surgery with the Acquired Haemorrhagic Coagulation Factor XIII(13) Deficiency: Two Case Reports.

Two women, aged 81 and 61, became haemorrhagic after surgery. Their previous surgeries were uneventful with no unexpected bleeding observed. Blood tests prior to the current surgeries indicated normal values including those related to coagulation.

Limitation of total hip arthroplasty of the acetabular roof by press-fit without screw fixation: discussion of a biomechanical study.

In total hip arthroplasty of the acetabular roof fixed by press-fit without screw fixation, there is little possibility for loosening to occur, because it is difficult for wear debris to enter between the cup and the acetabular roof, as screw holes are not present. However, stability is provided only by contact. In the case of acetabular dysplasia, it is not well understood whether sufficient initial fixation power is provided.

[Norovirus gastroenteritis in adult].

Noroviruses cause epidemic and sporadic acute gastroenteritis in both children and adults. There is a wide range of genetic diversity among the noroviruses, which are subdivided into genogroups and further classified into genotypes. The onset of illness is typically abrupt and often includes vomiting and diarrhea.

[Severe community-acquired pneumonia due to Acinetobacter baumannii].

A 78-year-old man with COPD was admitted in August 2010 complaining of productive cough and fever of 38 degrees C for 2 days. He was admitted with septic shock and pneumonia of the right upper lobe. Despite antibiotic administration, infiltration progressed to the right lung and lower left lung after 24 hours, and he developed acute respiratory distress syndrome (ARDS) and disseminated intravascular coagulation.
