Radiographic morphometry of the distal end radius in Anatolian population / Morfometría radiográfica del extremo distal del radio en la población de Anatolia

SUMMARY: Distal radius fractures are one of the most common orthopedic injuries encountered by orthopedic surgeons. Correction of dorsal tilt and radial height is essential to restore normal biomechanics of the wrist joint. Comprehensive knowledge of the morphometry of the distal radius of the local population becomes critical for the treating surgeon. This study aims to report the morphometry of the distal radius in the Anatolian population and compare it with similar studies in other races and humans. Radiographs of one hundred and twenty-four people were included in the study. Four radiological parameters were examined on all radiographs: radial height, radial tilt, ulnar variance, and palmar tilt. Radial tilt was 23.35°±1.96; palmar tilt was 15.7°±2,87 radial height (mm) was 10.55±4.34, ulnar variance (mm) was 0.32±1.79. The highest rate of negative ulnar variance was found. According to the study's results, reference data varying by race for anatomical fit should be considered in treating DER injuries.

Las fracturas de la parte distal del radio son probablemente las lesiones ortopédicas más comunes que encuentran los cirujanos ortopédicos. La corrección de la inclinación dorsal y la altura radial es esencial para restaurar la biomecánica normal de la articulación de la muñeca. El conocimiento integral de la morfometría del radio distal de la población local es importante para el cirujano tratante. Este estudio tuvo como objetivo reportar la morfometría de la parte rdistal del radio en la población de Anatolia y compararla con estudios similares en otras razas y humanos. Se incluyeron ciento veinticuatro radiografías simples consecutivas de la articulación de la muñeca. Se examinaron cuatro parámetros radiológicos: altura radial, inclinación radial, variación ulnar e inclinación palmar. El ángulo de inclinación radial fue de 23,35±1,96; el ángulo de inclinación palmar fue de 15,7±, la altura radial (mm) fue de 10,55±4,34, la varianza ulnar (mm) fue de 0,32±1,79. Se encontró la tasa más alta de varianza ulnar negativa (43,5%). Los resultados de este estudio deben tenerse en consideración al tratar fracturas de la parte distal del radio, con datos de referencia que varían según la raza para el ajuste anatómico.

Study on the importance of radial height restoration in type C distal radial fracture and related therapy / 重庆医学

Objective To study the importance of radial height restoration in the type C distal radial fractures and selection of therapeutic method.Methods Sixty-one cases of type C distal radial fractures in the department of joint orthopedics and traumatic orthopedics of affiliated traumatic and orthopedic hospital of Guangzhou university of Chinese medicine from June 2013 to September 2015 were retrospectively analyzed, including 34 cases of C1 type,14 cases of C2 type and 13 cases of C3 type according to the AO/ASIF fracture classification, the cases were divided into the manual reduction and splint external fixation group (27 cases), external fixator group (18 cases) and plate screw internal fixation group (16 cases).The radial height, palm inclination angle, ulnar inclination angle and Gartland-Werley (G-W) score after treatment were compared among various groups.Results Fifty-eight cases were followed up.The radial height, ulnar inclination angle and G-W score had statistical difference among 3 groups (P0.05);the difference of radial height and ulnar inclination angle between the external fixator group and plate screw internal fixation group had no statistical significance (P>0.05), but there were statistically significant differences when these two groups were compared with the manual reduction and splint external fixation group respectively (P0.05) , but there were statistically significant differences when these two groups were compared with the the plate screw internal fixation group respectively (P<0.05).Conclusion The radial height restoration may better recovery ulnar inclination angle and improve the joint function.

Distal radius morphometry of Indonesian population.

Background: Distal radius morphometry (radial inclination, palmar tilt, radial height, and ulnar variance) is an important parameter in the evaluation and treatment of distal radius fractures in which anatomical alignment must be corrected. Currently, treatment of distal radius fractures in Indonesia is still based on morphometry of western population or from the contralateral side. The aim of this study is to determine distal radius morphometry of Indonesian population and to compare between right and left side, male and female gender. Methods: Distal radius morphometry was measured from 400 plain X-ray of right and left wrist AP and lateral projection. Samples were taken consecutively in Moh. Ridwan Meuraksa Army Hospital, Jakarta, from June to September 2010. Radial inclination, palmar tilt, radial height, and ulnar variance was measured. Data were recorded using tables and grouped between male and female, right and left side, statistical analysis was performed using Mann-Whitney test. Results: From 400 plain X-ray evaluated, there were 300 males and 100 females with the mean age of 25.5 years old (18-48). The mean of radial inclination was 23.99 ± 3.75°, palmar tilt 13.76 ± 4.36°, radial height 11.31 ± 1.66 mm, and ulnar variance -0.45 ± 2.03 mm. There were statistically significant differences between right and left side of radial inclination, palmar tilt, radial height, and ulnar variance. There was also statistically significant difference between male and female. Conclusion: Distal radius morphometry in Indonesian population may provide valuable data for the treatment of distal radius fractures. The use of contralateral side as reference should be reconsidered.
