AbstractThe purpose of the study was to develop a deep learning network for estimating and constructing highly accurate 3D bone models directly from actual X-ray images and to verify its accuracy. The data used were 173 computed tomography (CT) images and 105 actual X-ray images of a healthy wrist joint. To compensate for the small size of the dataset, digitally reconstructed radiography (DRR) images generated from CT were used as training data instead of actual X-ray images. The DRR-like images were generated from actual X-ray images in the test and adapted to the network, and high-accuracy estimation of a 3D bone model from a small data set was possible. The 3D shape of the radius and ulna were estimated from actual X-ray images with accuracies of 1.05 ± 0.36 and 1.45 ± 0.41 mm, respectively.

Abstract Background The Ilizarov segmental bone transport technique can be applied in the reconstruction of the bone defects with less invasive fashion and more versatility compared to other methods, while most studies were focused on the lower extremity. The purpose of this study was to evaluate the effectiveness of the Ilizarov segmental bone transport technique in the treatment of diaphyseal forearm bone defects caused by infection. Methods This study included 12 patients with diaphyseal forearm bone defects caused by infection, who underwent bone transport procedures using the monolateral external fixator at our institution from January 2010 to January 2018, including 10 males and 2 females with a mean age of 39 years (range 23–57 years). Patient’s demographic data and clinical outcomes at least two years follow-up after removing the external fixator were collected and retrospectively analyzed. The functional results were evaluated by the questionnaire of Disability of Arm, Shoulder and Hand (DASH) and the modified Mayo wrist score (MWS) at the final follow-up. Results There were 10 radii and 2 ulnae bone transport procedures collected. The average defect size was 5.1 cm (4-6.5 cm). All patients were successfully followed up with a mean period of 28.2 months (24 to 36 months) and achieved infection-free union. There was no recurrence of infection observed. The mean external fixation time was 232.6 days (182 to 276 days), and the mean external fixation index was 46.3 days/cm (40.9 to 61.8 days/cm). The mean DASH score was 30.6(18 to 49) preoperative, while 13.8 (5 to 26) at the final follow-up. The average modified MWS improved from 68.8 (55 to 80) pre-operatively to 83.8 (65 to 90) at the final follow-up. All the differences between the preoperative and final scores were statistically significant (p < 0.05). Almost all the patients achieved satisfactory clinical outcomes and were able to perform activities of daily living. Conclusions Ilizarov segmental bone transport technique is an alternative and effective method for the treatment of diaphyseal forearm bone defects caused by infection, and this method acquired satisfactory clinical outcomes.

Background Though most of the pediatric diaphyseal forearm bone fracture can be treated with closed reduction and cast application, indications for operative intervention in pediatric both-bone forearm fractures include open fractures, irreducible fractures, and unstable fractures. Controversy exists as to what amount of angulation, displacement, and rotation constitutes an acceptable reduction. Objective To review union time and functional outcome of pediatric diaphyseal forearm bone fracture managed with intramedullary rush pin by closed or open reduction. Methods Fifty patients with both bone fracture of forearm were treated with intramedullary rush pin by closed or open reduction were included in the study and followed up for minimum six months for radilological and functional outcome. Results Out of 50 patients, 31 underwent closed reduction and 19 underwent open reduction. All fractures maintained good alignment post operatively. Forty seven patients had excellent results with normal elbow range of motion and normal forearm rotation and three patients had good results. In all patients good radiological union was seen in three months time. Eight patients had minor complications including skin irritation over prominent hardware, backing out of ulnar pin, superficial skin break down with exposed hardware. Twenty-three (46%) patients had undergone implant removal at an average of 6 months (range 4-8 months) under regional or general anesthesia Conclusion Fixation with intramedullary rush pin for forearm fracture is an effective, simple, cheap, and convenient way for treatment in pediatric age group.

Introduction: Orthopedic conditions include a range of condition varying from traumatic injuries, congenital anomalies, chronic back-pain, arthritis, rheumatologic conditions, and other. In Nepal, approximately 2.35 million people are living with musculoskeletal conditions in which 175,000 people are suffering with MSD from non-traumatic causes. The aim of the study is to observe the clinical and demographic pattern of orthopedic problems presenting in the hospital. Methods: A descriptive cross-sectional study was done in All Nepal Hospital Private Limited in the month of November. The data from the medical record section was retrospectively collected. Sample size of 384 was included and convenience sampling technique was used. The descriptive statistical analysis was done. Results: Eight hundred forty four cases were included in the study. Implant removal was the main condition for admission in the hospital 105 (12.44%) followed by Forearm Bone Fracture 84 (9.95%) and Cut Injury 64 (7.58%). Most cases presented during the time 6 PM to 12 AM 312 (36.96%). Conclusions: Most of the orthopedic cases presented in the evening and night time. Implant removal, forearm bone fracture and cut injury form the major bulk of the cases.
