Embolization for haemomediastinum due to spontaneous rupture of oesophageal branch arising from an unusual origin (inferior thyroidal artery) after vomiting: a case report.

Spontaneous rupture of the oesophageal artery is rarely observed in clinical practice and may lead to a haemomediastinum, which is a potentially life-threatening condition. Among these conditions, a mediastinal haemorrhage from oesophageal branches of the bronchial artery is the most frequently reported. However, rupture of oesophageal branches arising from the inferior thyroid artery (ITA) has never been reported to date.

Outcomes of Surgical Treatment of Acetabular Fractures with a Minimum of 1-Year Follow-up.

Backgroud: Acetabular fractures are rare and challenging to treat, and the surgeon's learning curve for managing these fractures is steep. The incidence of acetabular fractures is low, making it difficult to conduct single-surgeon, single-center studies. Therefore, multi-surgeon and multi-center studies may produce inconsistent outcomes compared to those of single-surgeon, single-center studies.

Far cortical locking constructs for fixation of distal femur fractures in an Asian population: A prospective observational study.

Background: The stiffness of locked plates suppresses healing process, prompting the introduction of far cortical locking to address this issue. This study aimed to demonstrate the clinical efficacy of far cortical locking constructs in treating distal femoral fractures in an Asian population.

Methods: This multicenter prospective observational study was conducted at four university hospitals between February 2018 and February 2021.

Posterior deltoid-sparing approach for displaced inferior or posterior glenoid fossa fractures: technical note and case series.

Scapular surgery has usually been performed through the posterior Judet approach. This approach allows access to the entire posterior scapular body, but causes significant soft tissue damage and detaches the deltoid muscle. To date, there has been no clinical study of a deltoid-preserving approach to access the joint for displaced postero-inferior glenoid fractures (Ideberg type II or Ib).

Surgical outcomes of acetabular fracture of elderly patients with superomedial dome impaction.

This study aimed to investigate the outcomes of elderly acetabular fractures according to the reduction of impacted dome fragments. A retrospective cohort study was performed in two institutions. Fifty-four patients aged ≥ 60 years with acetabular fractures were enrolled.

The Clinical Efficacy of Contouring Periarticular Plates on a 3D Printed Bone Model.

We report our experience of preoperative plate contouring for periarticular fractures using three-dimensional printing (3DP) technology and describe its benefits. We enrolled 34 patients, including 11 with humerus midshaft fractures, 12 with tibia plateau fractures, 2 with pilon fractures, and 9 with acetabulum fractures. The entire process of plate contouring over the 3DP model was videotaped and retrospectively analyzed.

Irreducible Ankle Fracture Dislocation Because of Tibialis Posterior and Flexor Digitorum Longus Tendon Entrapment in the Interosseous Membrane: A Case Report.

Case: We describe the case of a 63-year-old man with anterior ankle dislocation and fracture confirmed by x-ray. Postreduction x-ray and computed tomography (CT) revealed Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) type 44C3 and Lauge-Hansen pronation-external rotation-type ankle fractures.

Conclusion: This was a rare case of ankle fracture dislocation because of entrapment of the tibialis posterior and flexor digitorum longus tendons in the interosseous membrane.

Open reduction versus closed reduction in internal fixation of displaced femoral neck fracture in children: a systematic review and meta-analysis.

Background: The quality of reduction is an important factor affecting clinical outcomes for displaced femoral neck fractures (FNFs). However, concerns remain about the invasiveness of open reduction and internal fixation (ORIF) as compared to that of closed reduction and internal fixation (CRIF), and the choice between ORIF and CRIF as an optimal treatment strategy for displaced pediatric FNF remains controversial.

Materials And Methods: MEDLINE, Embase, and the Cochrane Library were systematically searched for studies published up to December 22, 2022, that compared ORIF and CRIF techniques for treating FNF in children.

Femoral head fracture with large crushed defect in weight-bearing area treated with autologous osteochondral transplantation (repositionplasty): A case report.

Rationale: Femoral head fracture is a rare type of fracture commonly associated with hip dislocation. Femoral head fracture treatments include conservative treatment, fragment excision, open reduction, internal fixation, and arthroplasty. In cases of young patients, open reduction and internal fixation are preferred over arthroplasty.

Outcome of multi-staged induced membrane technique based on post-debridement cultures for the management of critical-sized bone defect following fracture-related infection.

The authors' institution utilizes multi-staged induced membrane technique protocol based on post-debridement culture in treating patients with critical-sized bone defect in lower extremity due to infected nonunion or post-traumatic osteomyelitis. This study aimed to evaluate the success rate of this limb reconstruction method and which risk factors are associated with recurrence of infection. 140 patients were treated with multi-staged induced membrane technique from 2013 to 2018 and followed up more than 24 months after bone grafting.

Radiographic rotational profiles of the proximal and distal humerus: analysis of 46 computed tomography scans with 3-dimensional simulation.

Background: To date, no study has investigated the radiographic rotational profiles (RRPs) of the proximal and distal humerus. However, malrotation after minimally invasive surgery for humeral fracture has been an unsolved problem. Therefore, we aimed to investigate the RRPs of the proximal and distal humerus that linearly correlate with rotational status and show significant differences as the rotational status changes.

Impact of the COVID-19 Pandemic on Mortality Following Hip and Knee Joint Arthroplasty Surgeries: A Systematic Review and Meta-Analysis.

We performed a meta-analysis comparing the mortality rates after hip and knee joint arthroplasty between the coronavirus 2019 (COVID-19) pandemic and pre-pandemic periods. The purpose of present study was to investigate the impact of the COVID-19 pandemic on mortality rates after hip and knee joint arthroplasty. We systematically searched the MEDLINE, Embase, and Cochrane Library databases for studies published up to 28 March 2022.

The risk factors for subsequent fractures after distal radius fracture.

Introduction: The purpose of this study was to evaluate the risk factors for subsequent fractures after distal radius fracture (DRF).

Materials And Methods: We retrospectively reviewed 705 patients with DRF who performed dual-energy X-ray absorptiometry within six months before or after the DRF and followed more than 12 months. We identified patients with subsequent fractures and multivariate logistic regression analyses were conducted with demographic information, underlying disease status, and bone fragility parameters at the time of DRF to evaluate the risk factors for subsequent fractures.

Stress fracture after implant removal from the tibia reconstructed by the induced membrane technique: A case report.

Background: The induced membrane technique promotes vascularization and corticalization of the grafted bone and has become one of the mainstays in treatment of segmental bone defects. However, there are clinical concerns regarding the quality of bony consolidation using the induced membrane technique including a thin cortex formation and cortical notching after consolidation. We present the case of a tibial stress fracture in the bone reconstructed by the induced membrane technique after implant removal.

The effect of antifibrinolytic agents in periacetabular osteotomy: A systematic review and meta-analysis.

Background: Periacetabular osteotomy (PAO) is a major hip preservation surgery for developmental dysplasia of the hip. It is inevitably associated with significant blood loss, so it requires frequent transfusions and could be a cause of perioperative morbidity. However, to date, a large number of studies has not evaluated the effect of antifibrinolytic agents in PAO.

Delayed bladder perforation due to screw loosening after pelvic ring injury surgery: a case report.

Pelvic ring injuries have high mortality and morbidity rates, and they are difficult to treat because accompanying injuries to the pelvic organs, genitourinary organs, and neurovascular tissues are common. Genitourinary injuries are common comorbid injuries that have been reported to occur in 5% to 6% of all pelvic ring injuries. However, these injuries usually occur simultaneously with the pelvic ring injury, whereas relatively little research has dealt with genitourinary injuries that occur after treatment of a pelvic ring injury.

Aortic Injury After Shoulder Reduction in a Patient with Multiple Rib Fractures: A Case Report.

Case: A 74-year-old woman presented with multiple rib fractures, hemothorax, spleen rupture, and right shoulder dislocation. Shoulder joint reduction was performed using the traction-countertraction method. An injury to the descending aorta, caused by the seventh rib, was confirmed.

The effect of regional nerve block on perioperative delirium in hip fracture surgery for the elderly: A systematic review and meta-analysis of randomized controlled trials.

Introduction: With minimal systemic toxicity, an analgesic effect of regional nerve block (RNB) has been proved in hip fracture cases. Analgesia was expected to reduce delirium by controlling pain, a known predisposing factor for delirium. We performed a meta-analysis to investigate the effect of RNB on delirium after hip fracture surgery in elderly patients.
