  • Stress Fracture of the fifth metatarsal bone as a late complication of total knee arthroplasty
    The Kobe journal of the medical sciences, 2009
    Co-Authors: Hiroyuki Fujioka, Juichi Tanaka, Takeshi Makino, Atsuyuki Inui, Hiroaki Hirata, Issei Nagura, Takeshi Kokubu, Shinichi Yoshiya, Masahiro Kurosaka
    Abstract:

    A 64-year-old man had undergone a right total knee arthroplasty (TKA) as treatment for osteoarthritis of the knee. Six months after the TKA, the patient sustained a Stress Fracture of the left fifth metatarsal bone, which was a contralateral side of the TKA, without any apparent trauma or cause. The Fracture was treated with internal fixation using a screw and low-intensity pulsed ultrasound treatment was added. During two-year followup after internal fixation of the fifth metatarsal Fracture, he had no complaints in the knee or foot. The patient felt anxiety of breakage or loosening of the implant of TKA and the patient had been walking bearing mainly on his left leg and foot which was a contralateral side of the TKA. The cause of the Stress Fracture of the fifth metatarsal bone was speculated to be excessive Stress of weight bearing to the left foot during walking. The physicians should be aware of the risk of Stress Fracture of the fifth metatarsal bone as one of a rare late complication associated with TKA. It is very important to educate the patients, explaining the risk of breakage or loosening of the implant of TKA and instructing the adequate physical and mental benefits of walking.

  • bilateral pedicle Stress Fracture in a patient with lumbar spinal stenosis a case report
    Journal of Spinal Disorders & Techniques, 2008
    Co-Authors: Minoru Doita, Hiroyuki Fujioka, Takatoshi Shimomura, Kotaro Nishida, Koichiro Maeno, Masahiro Kurosaka
    Abstract:

    Study design A case of bilateral pedicle Stress Fracture in a patient with lumbar spinal stenosis is reported, and the literature is reviewed. Objectives To report a rare case of bilateral pedicle Stress Fracture without a history of major trauma or surgery. Summary of background data Bilateral pedicle Fracture is a rare entity and few cases have been reported in the literature. All the reported cases had some underlying causative factors like previous spine surgery or Stress-related activities. To the best of the authors' knowledge, only 1 case of bilateral pedicle Stress Fracture without a history of trauma, previous spine surgery, or Stress-related activities has been reported. Method A 57-year-old man presented with low back pain and radiating pain in left leg that was exacerbated after walking. Plain radiograph showed severe degenerative changes at L4-5 level. Magnetic resonance imaging revealed lumbar spinal stenosis at L2-3, 3-4, and 4-5 levels. A computed tomography demonstrated bilateral L4 pedicle Stress Fracture. The patient was treated with decompressive laminectomies of L3-5, followed by posterior spinal fusion with rigid pedicle screw fixation and autogenous bone graft mixed with hydroxyapatite. Results The patient achieved pain relief and returned to normal activity. Conclusions Stress Fracture of the pedicle within the proximal vertebra of a severely degenerated lumbar spine is an uncommon entity. It may, however, be an additional source of symptoms in patients with lumbar spinal stenosis who present with further back pain. Surgeons caring for this group of patients should be aware of this condition.

  • Stress Fracture of the Second Metacarpal Bone in a Badminton Player
    2008
    Co-Authors: Koji Fukuda, Hiroyuki Fujioka, Ikuo Fujita, Harunobu Uemoto, Takafumi Hiranaka, Mitsuo Tsuji, Masahiro Kurosaka
    Abstract:

    We present a rare case of Stress Fracture of the second metacarpal bone. A 14-year-old girl felt pain on the dorsal aspect of the right wrist without any history of major trauma, when she played a smash during a game of badminton. On the radiographs, periosteal reaction was detected on the ulnar aspect of the base of the second metacarpal bone. She was treated conservatively and she returned to the original activity level. Stress Fractures are partial or complete Fractures of a bone resulting from its inability to withstand Stress applied during repetitive trauma. Stress Fractures of the lower extremity, such as the tibia and the metatarsal bone, are common injuries in physically active athletes; however, Stress Fractures of the upper extremity are significantly less common 2,8. In this report, we present a Stress Fracture of the second metacarpal bone in a badminton player at junior high school. CLINICAL CASE A 14-year-old, right handed, young woman felt pain on the dorsal aspect of the right wrist without any history of major trauma, when she played a smash during a game o

  • Stress Fracture of the olecranon in an adult baseball player
    Knee Surgery Sports Traumatology Arthroscopy, 2006
    Co-Authors: Noriyoshi Nakaji, Juichi Tanaka, Hiroyuki Fujioka, Shinichi Yoshiya, Katsumasa Sugimoto, Kenji Fujita, Masahiro Kurosaka
    Abstract:

    Stress Fractures of the olecranon caused by repetitive Stress force have infrequently been reported as a cause of elbow pain in adult athletes, engaged in throwing and pitching sports. We diagnosed as a Stress Fracture of the olecranon by clinical and radiographic findings and treated surgically. The patient returned to playing baseball at a competitive level and was asymptomatic 4 months after the first operation. However, the patient re-injured the olecranon and a second surgical treatment was performed almost 1 year after the first operation. After the second surgery, the patient returned to playing baseball at a competitive level and was free from elbow symptoms. We presented a Stress Fracture of the olecranon in a semi-professional adult baseball player and suggested that surgical treatment is necessary.

  • Stress Fracture of the first rib in a soccer player a rare etiology of shoulder pain
    Journal of Shoulder and Elbow Surgery, 2003
    Co-Authors: Tomoyuki Matsumoto, Masahiro Kurosaka, Hiroyuki Fujioka, Shinichi Yoshiya, Kenji Fujita, Masaya Tsunoda, Kosaku Mizuno
    Abstract:

    AStress Fracture of the first rib rarely occurs as a sportsrelated injury but when seen occurs in young adults or older adolescents who engage in activities involving repetitive use of the upper extremities, such as baseball. We report the case of a young male soccer player who sustained a Stress Fracture of the first rib without repetitive use of the upper extremities. We speculate that heading the ball in soccer was the cause of this condition. To our knowledge, this is the first report in the English-language literature of a patient with a Stress Fracture of the first rib who was not involved in repetitive use of the upper extremities.

  • ground reaction forces and bone parameters in females with tibial Stress Fracture
    Medicine and Science in Sports and Exercise, 2004
    Co-Authors: Kim L Bennell, Kay M Crossley, Jyotsna Jayarajan, Elizabeth Walton, Stuart J Warden, Stephen Z Kiss, Tim V Wrigley
    Abstract:

    Purpose: Tibial Stress Fracture is a common overuse running injury that results from the interplay of repetitive mechanical loading and bone strength. This research project aimed to determine whether female runners with a history of tibial Stress Fracture (TSF) differ in ground reaction force (GRF) parameters during running, regional bone density, and tibial bone geometry from those who have never sustained a Stress Fracture (NSF). Methods: Thirty-six female running athletes (13 TSF; 23 NSF) ranging in age from 18 to 44 yr were recruited for this cross-sectional study. The groups were well matched for demographic, training, and menstrual parameters. A force platform measured selected GRF parameters (peak and time to peak for vertical impact and active forces, and horizontal braking and propulsive forces) during overground running at 4.0 m.s(-1). Lumbar spine, proximal femur, and distal tibial bone mineral density were assessed by dual energy x-ray absorptiometry. Tibial bone geometry (cross-sectional dimensions and areas, and second moments of area) was calculated from a computerized tomography scan at the junction of the middle and distal thirds. Results: There were no significant differences between the groups for any of the GRF, bone density, or tibial bone geometric parameters (P > 0.05). Both TSF and NSF subjects had bone density levels that were average or above average compared with a young adult reference range. Factor analysis followed by discriminant function analysis did not find any combinations of variables that differentiated between TSF and NSF groups. Conclusion: These findings do not support a role for GRF, bone density, or tibial bone geometry in the development of tibial Stress Fractures, suggesting that other risk factors were more important in this cohort of female runners.

  • Stress Fracture of the ulna in a softball pitcher
    Journal of orthopaedics, 2016
    Co-Authors: Hiroyuki Fujioka, Juichi Tanaka, Tetsuo Nishikawa, Satoshi Koyama, Kenjiro Tsunemi, Yohei Takagi, Shinichi Yoshiya
    Abstract:

    Abstract Background/aims We present a rare case of Stress Fracture of the diaphysis of the ulna in a softball pitcher. Case A thirteen-year-old girl felt pain over the distal third of the right forearm during pitching. Stress Fracture was detected as callus formation of the ulna before Fracture displacement. When windmill pitching for softball, the pitcher rotates their arm around the shoulder joint and powerfully hits their forearm to their thigh, which is accompanied by simultaneous pronation of the forearm and flexion of the wrist. The ball is then released and this movement is known as “brushing”. Conclusions The typical throwing form in a softball pitcher can play an important role in Stress Fractures of the ulna.

  • treatment of Stress Fracture of the olecranon in throwing athletes with internal fixation through a small incision
    Sports Medicine Arthroscopy Rehabilitation Therapy & Technology, 2012
    Co-Authors: Hiroyuki Fujioka, Kenjiro Tsunemi, Yohei Takagi, Juichi Tanaka
    Abstract:

    The present study is a report of retrospective case series of Stress Fracture of the olecranon. Six patients presented posterior elbow pain in throwing in baseball and softball, but Fracture was not diagnosed in radiographs. We detected Stress Fracture of the olecranon using computed tomographic (CT) scan and treated the patient with internal fixation with a headless cannulated double threaded screw through a small skin incision. All patients returned to competitive level without elbow complaints after the operation. When throwing athletes present with unusual posterior elbow pain and no significant findings on radiographs, a CT scan examination should be performed. We recommend surgical treatment of internal fixation with a screw through a small skin incision, as a good option for Stress Fracture of the olecranon in order to allow early return to sports activity in competitive athletes.
