One-hundred-one cases of both-forearm-bone shaft fractures were retrospectively reviewed. All fractures were divided into the following three groups, according to the method used for internal fixation : open reduction and internal fixation ORIF group (plate osteosynthesis), IMN group, and HYBRID group (plate osteosynthesis for the radius and intramedullary nail for the ulna). The results were assessed based on the time to union, functional recovery, restoration of the ulna and radial bow, operating time, complications, and patient satisfaction. In the ORIF, IMN, and HYBRID groups, the average union time was 10.8, 14.9, and 11.5 weeks, respectively. No intergroup differences were observed in the functional outcomes. The ORIF and HYBRID groups had a significantly better radial bow ratio compared to the IMN group. All patients in the three groups achieved union, with the exception of a single case of nonunion in the IMN group. ORIF and HYBRID fixation resulted in a more anatomical restoration of radial bow ratio, compared to the contralateral side. Such significant differences in the restoration of the radial bow had no effect on the final functional outcomes and minimal effect on forearm range of motion. Although there are statistically significant effects on the final forearm range of motion, the difference was only 5°. Thus, if the indication is properly selected, our results suggest that hybrid fixation would be acceptable and effective treatment options for both-forearm-bone fractures in adults.

Correlation between dorsovolar translation and rotation of the radius on the distal radioulnar joint during supination and pronation of forearm / Sang Ki Lee in Acta Orthopaedica Belgica, Vol. 81/3 (Septembre 2015)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol. 81/3 (Septembre 2015) . - p.511-522 Titre : Correlation between dorsovolar translation and rotation of the radius on the distal radioulnar joint during supination and pronation of forearm Type de document : texte imprimé Auteurs : Sang Ki Lee, Auteur ; Young Dong SONG, Auteur ; Won Sik CHOY, Auteur Année de publication : 2015 Article en page(s) : p.511-522 Langues : Anglais (eng) Mots-clés : Distal radioulnar joint  carpal joints  computed tomography Résumé : This study aimed to describe the patterns of movements about radius and ulna in individual degrees of forearm rotation. And, we also determined the effect of forearm rotation on translation and rotation of the radius with reference to the ulna, and to measure the relationship between forearm rotation, translation and rotation of the radius. Computed tomography of multiple, individual forearm positions, from 90° pronation to 90° supination, was conducted in 26 healthy volunteers (mean age, 43.9 years) to measure dorsovolar translation and rotation of the radius in the DRUJ in each forearm position. The mean dorsovolar translations were within 1.99 mm at 90° pronation to -2.03 mm at 90° supination. The rotations of the radius were 71.20° at 90° pronation and -46.63° at 90° supination. There were strong correlations between degrees of forearm rotation and dorsovolar translation (r = 0.861, p < 0.001) and rotation of the radius (r = 0.960, p < 0.001), suggesting that the DRUJ, carpal joints, and rotatory laxity of the carpal ligament, especially in supination, contribute to forearm supination and pronation. These findings provide an understanding of wrist kinematics, are may be useful in reconstructive wrist surgery to achieve normal range of motion, and are may be helpful for the design of DRUJ reconstruction using prostheses.

LCP metaphyseal plate fixation for fractures of the distal third humeral shaft using brachialis splitting approach / Sang Ki Lee in Acta Orthopaedica Belgica, Vol.82/1 (March 2016)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol.82/1 (March 2016) . - p. 85-93 Titre : LCP metaphyseal plate fixation for fractures of the distal third humeral shaft using brachialis splitting approach Type de document : texte imprimé Auteurs : Sang Ki Lee Année de publication : 2016 Article en page(s) : p. 85-93 Langues : Anglais (eng) Mots-clés : humérus  fracture  chirurgie Résumé : The authors retrospectively studied the clinical and radiographic outcomes of locking compressive plate (LCP) metaphyseal plate fixation through the anterolateral approach in patients treated surgically for unstable distal third humeral shaft fractures. Twenty seven patients were treated surgically with LCP metaphyseal plate using brachialis splitting methods through the anterolateral approach. The mean arc of elbow motion was 132.4° with a mean flexion of 133.5° and mean flexion contracture of 1.1°. Three patients had a slight elbow flexion contracture with loss of 5° (n = 1), 10° (n = 1), and 15° (n = 1) of extension. The mean American Shoulder and Elbow Surgeons score was 92.6 points, which corresponded to excellent results in 26 shoulders and a good result in one. The mean Mayo Elbow Performance Score was 90.7 points, which corresponded to excellent results in 24 elbows, a good result in 2, and a fair result in 1. Treatment of distal third humeral shaft fracture using LCP metaphyseal plate through the anterolateral approach is an acceptable and alternative method that can provide good results.
