  • excessive Periosteal Reaction after total hip arthroplasty using a short tapered stem
    Orthopaedic Proceedings, 2018
    Co-Authors: S Takayama, Kazuhiro Oinuma, Y Miura, Tatsuya Tamaki, Kurato Jonishi, H Yoshii, Hideaki Shiratsuchi
    Abstract:

    ObjectiveWhile the short-stem design is not a new concept, interest has risen with increasing utilization of less invasive techniques. Especially, short stems are easier to insert through the direct anterior approach. In the radiographic evaluation of patients who underwent primary uncemented total hip arthroplasty (THA) using a TaperLoc Microplasty femoral component (Biomet, Warsaw, IN, USA), cortical hypertrophy was occasionally detected on three-month postoperative radiographs. The purpose of this study was to evaluate the radiographic changes associated with cortical hypertrophy of the femur three months postoperatively.MethodsBetween May 2010 and September 2014, 645 hips in 519 patients who received the TaperLoc Microplasty stem were evaluated. Six hips in four patients were lost to follow-up. Finally, 639 hips in 515 patients were included in this study; 248 hips underwent bilateral simultaneous THA and 391 hips underwent unilateral THA. There were 103 males and 412 females (average age, 63 ± 10.1 y...

Finally, 639 hips in 515 patients were included in this study; 248 hips underwent bilateral simultaneous THA and 391 hips underwent unilateral THA. There were 103 males and 412 females (average age, 63 ± 10.1 years; average height, 156 ± 8.13 cm; and average weight, 58 ± 12.2 kg). The postoperative radiographs immediately taken after the operation and three months postoperatively were compared. We evaluated cortical hypertrophy around the stem. Cortical hypertrophy >2 mm on anterior-posterior X-ray was defined as “excessive Periosteal Reaction” (Figure 1). Results Twenty-four (3.76%) of the 639 hips had an excessive Periosteal Reaction. Eight (1.25%) hips underwent bilateral simultaneous THA and sixteen (2.5%) hips underwent unilateral THA. With regard to the prevalence of the excessive Periosteal Reaction, there were no significant differences between the patients who underwent the unilateral procedure compared with those who underwent the bilateral procedure. Of these 24hips, 12 (50%) showed thigh pain in patients after surgery. The patients with an excessive Periosteal Reaction had an average age of 66 ± 9.02 years, an average height of 157 ± 6.4 cm, and an average weight of 61 ± 10.3 kg. There were no significant differences in age, height, and weight between the patients with an excessive Periosteal Reaction and all study patients. The thigh pain resolved spontaneously within three months after surgery in all patients, and no patient required revision surgery. Six (0.94%) hips had femoral periprosthetic fractures in the early postoperative period. Conclusions Excessive Periosteal Reaction, which was defined as cortical hypertrophy >2 mm on anterior-posterior X-ray three month postoperatively, occurred in 3.75% of the patients who received the TaperLoc Microplasty stem. Thigh pain occurred in half of the patients who had an excessive Periosteal Reaction. We speculated that this Reaction was caused by the concentration of the torque or vertical load on the limited area of the femur in the early postoperative period. This stress was accompanied by femoral periprosthetic fractures in the early postoperative period, and patients without femoral periprosthetic fractures experienced an excessive Periosteal Reaction with thigh pain.

  • Periosteal Reaction in systemic lupus erythematosus
    Joint Bone Spine, 2007
    Co-Authors: Hey Won Chung
    Abstract:

    Abstract Musculoskeletal complaints are the most common presenting symptoms in most of the patients with systemic lupus erythematosus (SLE). However, Periosteal new bone formation is an extraordinarily rare condition in SLE. We report a case of Periosteal Reaction in SLE. A 31-year-old woman with SLE presented with both knee pain. Radiographs revealed Periosteal Reactions in both femur and tibia and around the metaphysis of the right distal tibia. Periosteal Reaction can be caused by benign or malignant lesions and infection. We cannot find any other cause of Periosteal Reaction in our case after thorough evaluations. Periosteal Reaction in SLE might be associated with inflammatory vascular changes. This is the first report of Periosteal Reaction in SLE after the 1990s description and the first report in Korea.
