Huge Turret Exostosis of Metacarpus: A Case Report / 대한골관절종양학회지

A turret exostosis was known a smooth, dome-shaped extracortical collection of subperiosteal bone beneath the extensor apparatus. In most cases, turret exostosis involve middle and distal phalanges compared with involving metacarpal cases have been rarely reported in the literature.

Open Synovectomy in Diffuse Pigmented Villonodular Synovitis of Ankle Joint: A Case Report / 대한족부족관절학회지

Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. PVNS occurs in two types: localized and diffuse. Localized type is characterized by focal involvement of the synovium with either nodular or pedunculated masses, Diffuse type affects virtually the entire synovium. Diffuse type has reported more recurrence rate. We have experienced a patient who has diffuse type PVNS of ankle joint and report an optimal method of surgical treatment.

Fixation of Pipkin Fractures with Acutrak Screws: A Report of Three Cases

Femoral head fracture with posterior dislocation of the hip occurs relatively infrequently. Many treatment options exist for this condition. The fracture fragments of the femoral head can be internally fixed or removed depending on the severity of fracture comminution, fragment size, and location on the weight-bearing surface of the femoral head. In Pipkin type I and II fractures, the fragments are typically located anteriorly. Hence, it is important to strongly fix the fracture fragments to the femoral head rather than to excise them, in the interest of securing a better outcome. Even if the fragments are caudal to the fovea centralis, the discarding of large portions of the femoral head that are amenable to rigid fixation is not preferred. Three femoral head fractures were treated using Acutrak screws incorporated with a self-compression mechanism. We report the results and consider ways to use Acutrak screws.

Popliteal Artery Occlusion after Total Knee Replacement Arthroplasty: A Case Report

The injury of popliteal artery in association with a total knee arthroplasty is rare with the incidence reported 0.03% to 0.05%, but the result of popliteal artery occlusion is extremely poor. Preexisting peripheral arterial disease, flexion deformity, tourniquet use, inadequate procedure during TKA, close proximity of popliteal artery to posterior cortex of tibia plateau, all of these are likely to increase the risk of the injury of popliteal artery during a knee replacement operation. We have experienced a patient who developed an arterial complication in association with a total knee arthroplasty and report the treatment as well as the discussion about the mechanisms of injury of popliteal artery.
