Osteochondritis dissecans (OCD) is a pathologic condition of the subchondral bone which involves the articular cartilage. Unstable OCD can be fixed with various implants, including bioabsorbable materials. Bioabsorbable materials have several advantages. Removal of the implant is not required, and they have low interference on imaging studies, such as magnetic resonance imaging (MRI). This paper reports a case of surgical treatment using bioabsorbable pins for OCD lesion. MRI showed a displaced osteochondral lesion at medial femoral condyle. Arthroscopic reduction and fixation were attempted initially, but additional mini-open incision was needed to reduce the fibrotic fragment. The fragment was trimmed and fixed with two bioabsorbable pins. Union was achieved at the follow-up without complications.The use of bioabsorbable pins for OCD treatment may be one of successful treatment method.

Ipsilateral fractures of the femoral neck and shaft are relatively common injuries and accompany 2% to 9% of all femoral shaft fractures. On the other hand, it is extremely rare for these injuries to occur bilaterally. This paper reports the authors’ experience of a case with bilateral femoral neck and shaft fractures. The patient sustained multiple injuries, including liver laceration with hemoperitoneum, bilateral open fractures of the tibia, and bilateral femoral neck, and shaft fractures caused by a high-speed motor vehicle accident. Under the circumstances, damage-control orthopedic principles were applied, and external fixators were initially placed. After the patient’s general condition showed improvement, both femurs were fixed with a reconstruction nail. Fracture healing was achieved without complications, such as avascular necrosis of the femoral head. Despite the rare occurrence, this paper describes this case because these injuries must be managed with meticulous attention.

Villoglandular adenocarcinoma (VGA) is a rare subtype of cervical adenocarcinoma with a more favorable prognosis compared to conventional adenocarcinomas. Although the tumors are usually recognized on colposcopic examination due to the mainly exophytic growth pattern, they may be underdiagnosed as benign lesions by cytology because of their minimal cytologic atypia. We report the liquid-based cytology (LBC) findings of three histologically confirmed VGAs which we have recently identified. They were characterized by hypercellular smears on low-power examination with smooth-bordered three-dimensional papillary fragments. The nuclei were relatively uniform with irregular nuclear membranes. Nucleoli were small but distinct and macronucleoli were also seen. The abnormal architectural patterns such as papillary structures and nuclear overlapping and nuclear hyperchromasia are important clues to the diagnosis of VGA. In addition, nuclear membrane irregularity and prominent nucleoli can be recognized on LBC specimens, further facilitating its diagnosis.
