Aim. Osteogenesis imperfecta (OI) is characterized by bone fragility and long bones deformities. Most studies are dedicated to surgical treatment of diaphyseal fractures. To our knowledge, there are no reports giving recommendations about surgical treatment of distal femur intraarticular fractures. Clinical case. We describe the surgical treatment of a 14-year-old girl with OI who had intraarticular fracture of the left distal femur and fracture of a right femur diaphysis. Surgical treatment was complicated by migration of a titanium elastic nail and impaired consolidation, which had to be fixed with a plate and led to peri-implant fracture. Results were assessed before trauma and at 1 and 2 years after trauma with Gillette Functional Assessment Questionnaire (GFAQ) and Bleck score. Discussion. During surgical treatment of comminuted intraarticular distal femur fractures in patients with OI, we had to use big cancellous screw that made implantation in an intramedullary fixator more difficult. Internal fixation with a plate in patients with OI is associated with high risks of peri-implant fracture. Conclusion. For treatment of comminuted intraarticular fracture of the distal femur, it is necessary to have large variety of internal fixators, follow the principles of absolute and relative stability, and be familiar with minimally-invasive techniques.

Background: Mismatch of intramedullary nails with the bowing of femur is a frequent clinical finding. Previous studies showed inconsistent results. Methods: We present an algorithm of region growing territory method to get the radii of the anterior bowing of femur. We also tested it on ten radiographs. Plain radiographs of the lateral view of femur from five men and five women taken between January and August 2014 in Taipei Hospital were chosen randomly. The curvature of femur outline and medullary canal were measured for three times each. Radii of curvature of whole femur, proximal, middle and distal parts were calculated and analyzed. Results: The coefficient of variation of the 240 measurements ranged from 0.007 to 0.295 and averaged 0.088. The average radii of curvature of the whole, proximal, middle, and distal femur were 1318 mm, 752 mm, 1379 mm, and 599 mm, respectively. At the distal part of the femur, the radius of curvature of the femur outline (452 mm) was smaller than the medullary canal (746 mm) (p < 0.05). Women’s femur was straighter than men’s when we compared the whole length (1435 mm vs. 1201 mm, p < 0.05). The radii we calculated were smaller than the current intramedullary nails. Conclusion: The results showed that the inter-observer and intra-observer differences are acceptable, support the impression that different bowing conditions existed for Asians as compared to Caucasians, and also indicate the mismatch of current instruments to the curvature of femur.

Rare Association

Fractures of the supracondylar and intercondylar region of the distal femur usually result from high velocity injury that is uncommonly associated with violation of the integrity of the extensor mechanism. The consequences of missed quadriceps injury associated with a distal femur fracture are devastating. The present case report illustrates the importance of recognizing the rare association of quadriceps tear with distal femoral fractures, an appropriate surgical approach to repair the tear as well as fixation of fracture, and a protocol of postoperative rehabilitation to achieve a successful outcome.
