Objective To find a satisfied repairing method which can complete the functional cheiloplasty while avoiding the visible scar after the cheiloschisis II operation for bilateral cleft lip. Methods The functional operation was carried out in subcutaneous layer by incising along the outline of the nose and the mouth. Results A satisfied effect was achieved after 6 months to 2 years' follow up in 15 cases of the patients (4 cases of bilateral cleft, 11 cases of cheiloschisis). Conclusions The new operation method has improved the traditional method of cheiloplasty. It can effectively repair the secondary defection in nose and mouth resulted from the cheilochisis operation. It can rebuild the orbicularis oris muscle and repair the diseased alar catilage as well. Furthermore, it not only brings a natural looking appearance, but also a natural function and an invisible incision scar. [

Objective:To explore the ability of training on a three-dimensional motion platform to improve the walking ability and skill in the activities of daily living of hemiplegic stroke survivors.Methods:A total of 70 stroke survivors with hemiplegia were randomly divided into a control group ( n=35) and an intervention group ( n=35). In addition to routine rehabilitation, the control group received 40 minutes of ground balance training, while the intervention group received 40 minutes of training on a three-dimensional motion platform 6 times a week for 4 weeks. Before and after the intervention, step length, speed and frequency were evaluated in both groups using the Gait Watch 3D gait analysis system. Walking ability and ability in the activities of daily living were assessed using the de Morton mobility index (DEMMI) and the modified Barthel index (MBI). Results:Before the treatment, there was no significant difference in average step length, speed or frequency between the two groups. The average standing phase percentage on the affected side, percentage of double support period, DEMMI score, and MBI score also were not significantly different. After the treatment those indicators had improved significantly in both groups. The intervention group′s averages were then all significantly better than those of the control group.Conclusions:Three-dimensional motion platform training can improve the walking ability and skill in the activities of daily living of hemiplegic stroke survivors.

Objective:To compare the therapeutic effects of cannulated screws and Kirschner wires in the treatment of medial malleolar fractures of Salter-Harris types Ⅲ and Ⅳ in children.Methods:A retrospective study was conducted to analyze the data of 48 and 16 children who had been treated respectively at Department of Pediatric Orthopaedics, Fuzhou Second General Hospital, and Department of Pediatric Orthopaedics, Foshan Hospital of Traditional Chinese Medicine for medial malleolar fractures of Salter-Harris types Ⅲ and Ⅳ from June 2016 to June 2022. There were 32 males and 32 females with an age of 12 (10, 14) years; 31 left and 33 right sides were affected. By the Salter-Harris classification: type Ⅲ in 45 cases, and type Ⅳ in 19 cases. The patients were divided into 2 groups according to their internal fixation methods. Group A (44 cases) was subjected to internal fixation with cannulated screws and group B (20 cases) to internal fixation with Kirschner wires. At the last follow-up, anteroposterior and lateral X-ray films of their ankle joints were taken for imaging evaluation. Functional recovery of the affected limbs was evaluated based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring, and related complications were recorded.Results:The 2 groups were comparable because there were no significant differences in their preoperative general data except laterality ( P>0.05). All the patients were followed up for (37.3±21.5) months and achieved bony union. At the last follow-up, for groups A and B respectively, the distal lateral angle of the tibia was 89.0° (89.0°, 90.0°) and 89.0° (89.0°, 90.0°), the range of ankle motion was 73.5° (67.8°, 76.0°) and 70.0° (70.0°, 75.0°), and the good and excellent rate by the AOFAS ankle-hindfoot scoring was 97.7% (43/44) and 95.0% (19/20), showing no significant difference between the 2 groups ( P>0.05). There was a significant difference between the 2 groups in the incidence of premature physeal closure [36.4% (16/44) versus 65.0% (13/20)] ( P=0.033). Conclusions:In the treatment of medial malleolar fractures of Salter-Harris types Ⅲ and Ⅳ in children, internal fixation with both cannulated screws and Kirschner wires can lead to comparable efficacy in good functional recovery and imaging evaluation. However, fixation with cannulated screws may be more advantageous in reducing the risk of early closure of the epiphysis.

Objective:To explore the clinical features and surgical outcomes of greater trochanteric fractures of the femoral neck in children.Methods:A retrospective study was conducted to analyze the 5 children with greater trochanteric fracture of the femoral neck who had been treated at Department of Pediatric Orthopaedics, Fuzhou Second General Hospital from January 2011 to December 2020. There were 1 boy and 4 girls, with an age of (11.0±1.9) years. By the Delbet classification, all were type Ⅲ fractures. The time from injury to operation was (4.4±2.1) days. The children were treated with cannulated screws (1 case) or fixation with a pediatric hip plate (4 cases). The clinical features of such fractures were analyzed; the fracture union time and hip function and complications at the last follow-up were recorded.Results:The clinical features of greater trochanteric fractures of the femoral neck in children were: (1) involvement of 2 anatomic sites in a narrow region, (2) comminuted fractures, and (3) all Delbet type Ⅲ fractures. The follow-up time was (22.8±6.0) months. All the 5 children obtained bony union. The union time was (5.2±1.8) weeks for greater trochanteric fractures, and 8.0 (8.0,10.0) weeks for femoral neck fractures. Follow-up observed no necrosis of the femoral head, premature closure of the femoral head epiphysis, hip varus deformity, or length disparity between the lower limbs. Premature closure of the greater trochanteric epiphysis occurred in 2 children after surgery. According to the Ratliff scoring, the hip function was excellent in 3 cases and good in 2.Conclusions:Greater trochanteric fractures of the femoral neck in children are a special kind of proximal femoral comminuted fractures that affect 2 anatomic sites in a narrow region and belong all to Delbet type Ⅲ fractures. Open reduction and internal fixation with cannulated screws or a pediatric hip plate is a safe and effective treatment for such fractures.
