Publication Metadata only Survival times of patients with a first hip fracture with and without subsequent major long-bone fractures(2013-02-25) Chayanin Angthong; Wirana Angthong; Thos Harnroongroj; Masatoshi Naito; Thossart Harnroongroj; Faculty of Medicine, Thammasat University; Srinakharinwirot University; Mahidol University; Fukuoka UniversityObjectives: Survival rates are poorer after a second hip fracture than after a first hip fracture. Previous survival studies have included in-hospital mortality. Excluding in-hospital deaths from the analysis allows survival times to be evaluated... in community-based patients. There is still a lack of data regarding the effects of subsequent fractures on survival times after hospital discharge following an initial hip fracture. This study compared the survival times of community-dwelling patients with hipPublication Metadata only The second fracture of the same clavicle: Prevalence and fracture configurations(2012-12-01) Apichat Asavamongkolkul; Thos Harnroongroj; Wuttipon Suteeraporn; Narumol Sudjai; Thossart Harnroongroj; Mahidol UniversityObjective: To study second fracture at the same clavicle including prevalence, fracture configurations related to malunion types of the first fracture, and healing. Material and Method: Between 2008 and 2011, the authors reviewed medical records... and radiographs of the clavicles of patients who sustained acute clavicular fractures from motorcycle accident. Second fracture at the same clavicle and prevalence were studied. Malunion of the first fracture of the same clavicle were typed and configurationsPublication Metadata only The Clavicular Fracture : A Biomechanical Study of the Mechanism of Clavicular Fracture and Modes of the Fracture(2000-06-01) Thossart Harnroongroj; Chaichana Tantikul; Sayumporn Keatkor; Mahidol UniversityA clavicle is an S-shaped long bone whose biomechanical behavior is unlike that of a straight tubular long bone. When a clavicle is under a compression load along the axis, the force produces a middle one-third clavicular fracture. The present study... is a biomechanical study to confirm the clinical observations of the mechanism of the fracture and to discover the tension site and compression site of the fracture, using 12 fresh cadaveric clavicles, a universal testing machine and two special gripsPublication Metadata only Displaced articular calcaneus fractures: Classification and fracture scores: A preliminary study(2012-03-01) Thos Harnroongroj; Bavornrit Chuckpaiwong; Chayanin Angthong; Pongtep Nanakorn; Narumol Sudjai; Thossart Harnroongroj; Mahidol UniversityObjective: To review and group configurations of displaced articular calcaneal fracture advantaged for classification and radiographic fracture scores. Material and Method: Between 2002 and 2011, medical records and radiographs of patients who... sustained acute displaced articular calcaneal fractures were reviewed. The calcaneal fracture configurations were grouped as avulsion, bending, burst, or combination. Radiographic displaced articular calcaneal fracture score was designed to include BohlerPublication Metadata only Posterior acetabular arc angle of unstable posterior hip fracture-dislocation(2013-12-01) Thos Harnroongroj; Kongkhet Riansuwan; Narumol Sudjai; Thossart Harnroongroj; Mahidol UniversityPurpose: Posterior hip fracture-dislocation needs stability evaluation. A previous study in the normal acetabulum has shown that the coronal posterior acetabular arc angle (PAAA) could be used to assess an unstable posterior hip fracture. Our study... was designed to assess PAAA of unstable posterior hip fracture-dislocation and whether posterior acetabular wall fracture involves the superior acetabular dome. Methods: Using coronal computed tomography (CT) of the acetabulum and 3D reconstructionPublication Metadata only Major risk factors for the second contralateral hip fracture in the elderly(2009-12-01) Chayanin Angthong; Thongchai Suntharapa; Thossart Harnroongroj; Mahidol University; Faculty of Medicine, Thammasat UniversityObjectives: The purpose of this study was to determine which of the predisposing risk factors for the first hip fracture would continue to be effective for the development of the second hip fracture in the elderly. Methods: Data of 125 patients (31... men, 94 women) aged 55 years or older were evaluated, who sustained first (group 1, n=97) and second contralateral (group 2, n=28) hip fracture. Patients who were treated with bisphosphonate, calcitonin, or estrogen were excluded. ResultsPublication Metadata only Immediate stabilization of unstable pelvic fractures Versus delayed stabilization(1999-07-01) Saranatra Waikakul; Thossart Harnroongroj; Vichai Vanadurongwan; Mahidol UniversityTo compare the immediate and long term outcome of immediate stabilization of the unstable pelvic fractures to delayed stabilization with simple external fixation, the study was carried out as a paralell trial with 2 year follow-up. There were 112... patients with 69 males and 43 females who had unstable pelvic fractures. They were allocated randomly into 2 groups. In group 1, 40 patients, conventional management was performed while in group 2, 72 patients, reduction and anterior stabilization of pelvicPublication Metadata only The Reconstruction Twisted Wire-screws for Internal Fixation of Two- and Three-Part Fractures of the Proximal Humerus(1998-01-01) Thossart Harnroongroj; Vichai Vanadurongwan; Mahidol UniversityUsing the implants for internal fixation of the proximal humeral fractures has several problems which lead to complications and poor results of the fracture treatment. Because there is no suitable implant for internal fixation of the fracture.... Therefore, the reconstruction twisted wire was developed in 1990 to improve the results of the fracture treatment. Between 1990 and 1994, the reconstruction twisted wire was used in 31 patients whose ages ranged from 18 to 90 years. Sixteen patients hadPublication Metadata only Reconstruction of the pelvic brim and its role in the reduction accuracy of displaced T-shaped acetabular fracture(2000-05-01) Thossart Harnroongroj; Apichart Asavamongkolkul; Keerati Chareancholvanich; Mahidol UniversityOpen reduction of the displaced T-shaped acetabular fracture has a problem of accuracy of the fracture reduction. This study was carried out to demonstrate that the reconstruction of the pelvic brim by approaching the pubo-acetabular fragment plays... a role in the accuracy of the reduction of displaced T-shaped acetabular fractures. From 1975 to 1990, a retrospective study was carried out of 22 patients who sustained a displaced T-shaped acetabular fracture. The patients were operated on by openPublication Metadata only Posterior acetabular arc angle of the femoral head assesses instability of posterior fracture-dislocation of the hip(2013-06-01) Thossart Harnroongroj; Purinon Suangyanon; Theerawoot Tharmviboonsri; Thos Harnroongroj; Mahidol UniversityPurpose: Unstable posterior fracture-dislocation of the hip is determined by the wall defect or acetabular fracture index. The unstable hip is a result of inadequate posterior acetabular coverage of the femoral head from the posterior acetabular... wall fracture. In order to measure total posterior acetabular coverage of the femoral head and avoid using the contralateral acetabulum as a calculation reference, the posterior acetabular arc angle of the femoral head was measured to assess stability
