Postoperative periprosthetic fracture of the femur after hip arthroplasty is a serious complication that can be difficult to treat. Moreover, it has become more common in recent years, as the cases of hip arthroplasty and revisonal hip arthroplasty increase. We have experienced a postoperative periprosthetic fracture of th femur probably caused by a surgical instrument left in the medullary canal during hip arthroplasty. We report this case with reference to other related articles.
It is often difficult to eradicate infection and achieve bony union in postoperative infection after fracture fixation. Authors treated 14 such cases from February 1992 to February 1998, and followed up for 6 to 35 months. The purpose of this study is to review the clinical features of the postoperative infection and assess the treatment modality which influence the time required for attaining bony union and healing of infection. The results were as follows : 1. Primary fixation were left in place in 5 cases of stable fixation, and new external fixation and/or another fixations were required in 8 cases of unstable fixation. 2. Time required for achieving union was 4.7 months for stable primary fixation and 12.8 months for unstable primary fixation. 3. Time required for healing in infection was 3.5 months for stable primary fixation and 14.4 months for unstable primary fixation. 4. Bony union was delayed as the number of surgical procedures were increased. 5. Antibiotic cement beads were inserted for 5 cases into bony defect and dead space after curettage and sequestrectomy, and pus discharge was stopped after 8.8 weeks in average.

Operative treatment for closed fractures of the long bone has many advantages including early restoration of function by stable fixation, but has untoward problems including postoperative infection. The authors reviewed 19 cases of postoperative infection for closed long bone fracture during the period from January, 1990 to December, 1995 and analyzed about clinical, radiologic, pathologic findings and found causes of infection. Most cases were associated with multiple fractures of major bones or injuries to the vital organs and delayed over 48 hours after injury to operation. Operation time was prolonged due to the simultaneous operations for multiple fractures and associated open fractures at the same time. Staphylococcus aureus was the most frequent offending organism. Irregular resorption of plate-bone interface with resultant gap between the plate and bone, on the radiographic follow up, may indicate postoperative infection.
A fractures of the distal femur is an extremely complex fracture with which to deal. Poor bone stock, proximity to the knee joint, and a truncated shape make this area of the femur less suitable for internal fixation than other areas. Ideal care still somewhat controversial. Major complications include nonunion, delayed union, infection, loss of fixation, Joint stiffness and angular deformity, etc.
The authors reviewed postoperative tiblo-femoral angular changes from the twenty six cases of supracondylar and intercondylar fractures of the femur treated operatively from January, 1988 to December, 1991. Fractures of a single condyle were excluded. The fractures were fixed internally with dynamic condylar screw(DCS) in nine cases, anatomic plate in nine, dynamic compression plate(DCP) in six and others in two. During the periods of follow up there noted varus change of 3.7 degrees in average. We reviewed retrospectively these postoperative varus or valgus angular changes with reference to the degree of injury, type of fracture, time elapsed from injury to operation, kind of internal fixation device, initial bone graft and postoperative brace supplement. Less angular changes in the tiblo-femoral angle with better results were noted in cases with lower energy injuries, AO type Al, A2 or Cl fractures, operation within 1 week of injury, internal fixation with DCS, initial bone graft and postoperative corrective brace supplement.
