Observational Study
Open reduction combined with CORA-based osteotomy of the ulna in the treatment of missed Bado type I Monteggia injury: A retrospective study of 5 cases.
Open reduction combined with ulnar osteotomy is the most common approach to treating missed Monteggia injuries. The osteotomy is usually performed at the proximal ulna to ensure better healing and fewer complications. The purpose of this study is to present a center of rotation angulation (CORA)-based osteotomy of the ulna for treating Bado type I Monteggia injuries. ⋯ All patients had pain-free elbows with no neurological or vascular complications and no implant breakage. Patients showed excellent outcomes evaluated using the Broberg and Morrey index. Open reduction with a CORA-based osteotomy of the ulna for the treatment of missed Bado type I Monteggia injury with an obvious ulnar bowing deformity resulted in stable reduction of the radial head and excellent forearm function.

Observational Study
Corneal clarity measurements in healthy volunteers across different age groups: Observational study.
The aim of this study was to standardize and investigate the changes in corneal clarity with age. Densitometry software for the Oculus Pentacam was used to examine corneal clarity at different age groups. A total of 192 eyes from 97 healthy participants were included in this cohort comparative nonrandomized, cross-sectional study. ⋯ The values for CD, as well as for separate subdivisions based on layer and surface area, might provide a standard for use in further studies and clinical practice. This study established that relation between CD and age is differed when the cornea is divided into layers and zones. This study suggests that there are other factors that may play an essential role in corneal clarity as well as age.

The knee joint is an important weight-bearing joint, tibial plateau fractures affect knee function and stability. High-energy intra-articular fractures involving the tibial plateau can cause management-related problems such as wound dehiscence; severe comminution leading to malalignment; and delayed complications such as varus collapse, implant failure, and arthritis of the knee joint. The treatment of severe or complex tibial plateau fractures can be quite difficult. Traditional methods of open reduction and plating require extensive exposures, which may further compromise soft tissue and devascularize bone fragments, leading to infection. In this case, a novel device, double reverse traction combined with MIPPO technique, was used and provided the possibility of minimally invasive and personalized orthopedic surgery to treat severe comminuted Schatzker type VI tibial plateau fracture and tibial shaft fracture and got satisfactory results. ⋯ Double reverse traction combined with MIPPO technique can reduce the risk of surgical complications, such as bleeding, oozing, and wound infection. It can be applied in patients with comorbidities such as cardiac disease, hypertension, and heart failure who may otherwise not be candidates for surgery. The cost burden is lower than that of the traditional traction table.

Case Reports
Pancreatogenic choledocholithiasis in common bile duct stump after Roux-en-Y hepaticojejunostomy: A case report.
Choledocholithiasis in common bile duct (CBD) stump after Roux-en-Y hepaticojejunostomy (RYHJ) is incredibly rare and its pathophysiology is poorly understood. ⋯ This type of choledocholithiasis in CBD stump after RYHJ has never been reported before. We nominated it as "pancreatogenic choledocholithiasis," and pancreatobiliary reflux caused by a variant pancreatic duct may be the main cause.

Osteosarcomas are the most common primary malignant bone tumors in children and young adults; these tumors often affect the metaphyses of long bones such as the proximal humerus, proximal tibia, and distal femur. In contrast, osteosarcoma of the coracoid process is extremely rare. ⋯ A misdiagnosis or inadequate and/or delayed treatment for a coracoid process osteosarcoma could have grave consequences. Computed tomography and magnetic resonance imaging are essential for a diagnosis, and a biopsy can effectively confirm the diagnosis. Our findings suggest that considering only a single factor, or using incomplete information, can lead to an arbitrary diagnosis.
