Tadashi Tsukeoka, Yoshikazu Tsuneizumi, Kensuke Yoshino
BACKGROUND: Although sagittal tibial alignment in total knee arthroplasty (TKA) is important, no landmark exists to achieve reproducible slope. It is theoretically demonstrated that the preoperative planned distance between the skin surface and the rod can be a useful guide for the tibial slope in the previous imaging study. We conducted this retrospective study to confirm whether the results of the study are repeatable in an intra-operative situation. METHODS: Fifty-five consecutive TKAs using the distance from the extramedullary cutting guide rod to the skin surface as a reference guide for the tibial slope were performed and tibial component positioning was compared with 55 knees performed using the accelerometer-based portable navigation...

INTRODUCTION: The use of trans-sacral implants to treat fractures of the sacrum is limited by the variable pelvic anatomy. We were interested in how many trans-sacral implants can be placed per pelvis? If a trans-sacral implant cannot be placed in S1, where is the cortex perforated, and is the use of sacroiliac screws safe in these pelves? MATERIALS AND METHODS: 3D pelvic models were created from CT scans of 156 individuals without fractures (92 European and 64 Japanese, 79 male and 77 female, mean age 66...

BACKGROUND: Precise measurement of the tibial slope (TS) is crucial for realignment surgery, ligament reconstruction, and arthroplasty. However, there is little consensus on the ideal assessment. It was hypothesized that the tibial slope changes according to the acquisition technique and both tibial length as well as femoral rotation serve as potential confounders. METHODS: 104 patients (37 women, 67 men; range 12-66 years) were retrospectively selected, of which all patients underwent a 1...

INTRODUCTION: In 2012, the Korean central government selected trauma centers to provide effective treatment and reduce preventable mortality in severe trauma patients. General surgeons, thoracic surgeons, orthopedists, and neurosurgeons play pivotal roles in trauma centers, as most trauma patients require orthopedic procedures. This study aimed to underscore the importance of trauma orthopedic specialists (TOSs) by comparing treatment outcomes between a TOS and general orthopedists. PATIENTS AND METHODS: Orthopedic trauma patients with injury severity scores > 15 points, admitted to level 1 trauma centers between March 2015 and December 2016, were divided into the TOS group (treated by 1 orthopedic trauma specialist who treats trauma patients with no limitation in the joint of specialization) and the general orthopedist group (GOG; treated by several general orthopedists who manage both trauma and disease but are each specialized in a certain joint)...

Osteitis of the fingers is a serious infection that needs early diagnosis and appropriate surgical debridement and antibiotic treatment of the infected bone. If the effects of treatments are insufficient, long-term antibiotic treatment and repeated operations could be required. In worst cases, some patients may have to undergo amputation. Recently, the usefulness of the Masquelet technique in extensive traumatic bone defects has been reported. We herein describe two cases of immunocompromised patients with purulent osteitis involving joint destruction of the finger treated by two-stage arthrodesis using the Masquelet technique...
