Survival rates and risk factors for failure using an interposition vein graft for fingertip amputations with segmental vessel defects.

Purpose: This study aimed to compare survival rates and risk factors of replantation failures using an interposition vein graft in fingertip amputations with segmental vessel defects with those using simple end-to-end anastomosis in amputations.

Patients And Methods: Between 2004 and 2015, 776 (647 males and 129 females) with single Zone I or II amputations of digits underwent replantation. Among these, simple end-to-end anastomosis was performed in 698 replantations, while interposition vein grafts were used for either arterial or venous repair or both in 78 amputated fingertips.

The Impact of Educational Interventions on Osteoporosis Knowledge among Korean Osteoporosis Patients.

Background: The purpose of this study was to determine the impact of an educational intervention that includes information sharing about absolute fracture risk on the knowledge of osteoporosis and modifiable risk factors among Korean patients with osteoporosis.

Methods: Adults aged >50 years who visited the outpatient clinic for osteoporosis were recruited. Subjects with trauma-related fractures or pathological fractures were excluded.

Which one is more affected by navigation-assisted cup positioning in total hip arthroplasty: Anteversion or inclination? A retrospective matched-pair cohort study in Asian physique.

Introduction: The purpose of this study was to compare acetabular cup positioning using an imageless navigation-assisted total hip arthroplasty (THA) to a case-matched control group using the conventional technique in Asian physique.

Methods: Case matching controlled study using retrospectively collected data for THAs was done. Matching criteria were gender, age ± 5 years, and body mass index ± 5 kg/m.

The Effect of Patient Age on the Success Rate of Digital Replantation.

Background: The purpose of this study was to evaluate outcomes and risk factors for failure after digital replantation in elderly patients, with a special focus on the effect of patient age on replantation success.

Methods: Replantation patients older than 60 years were analyzed thoroughly to characterize outcomes and risk factors for failure in older patients. Survival rates of all age groups older than 20 years were then analyzed to determine the specific effect of patient age on replantation success.

Reconstruction of two fingertip amputations using a double thenar flap and comparison of outcomes of surgery using a single thenar flap.

Background: Although thenar flap for single fingertip amputation is a common and popular surgical technique, double thenar flap technique for patients with two fingertip amputations has rarely been reported in the literature. The purpose of this case-control study was to introduce the double thenar technique and compare the clinical outcomes between single thenar flap and double thenar flap surgical treatments.

Methods: From January 2005 to December 2014, 92 patients with single fingertip amputations were treated with thenar flap (Group I) and 28 patients with two fingertip amputations were treated with double thenar flap (Group II).

Clinical outcomes of a simultaneous replantation technique for amputations of four or five digits.

Purpose: Replantation of amputations separated by more than four digits is challenging microsurgery because of the technical demands and long operation time. The purpose of this report was to present the clinical and functional outcomes in patients with amputations of four or five digits using a simultaneous replantation technique.

Patients And Methods: Among the 43 patients who visited our institution due to amputation of four or five digits from 2004 to 2013, 35 patients (28 males and seven females) underwent simultaneous replantation of four or five digits.
