Staged Reconstruction

Abstract Background and purpose Total hip arthroplasty (THA) is a successful approach to treat unilateral symptomatic neglected hip dislocation (NHD). However, the extensive leg length discrepancy (LLD) can hereby only be partially corrected. In case of residual LLD of more than 2 cm, subsequent femoral lengthening can be considered. Patients/material/methods Retrospective analysis of clinical data and radiographs of five patients (age 38.1 (28–51) years) with unilateral NHD who underwent THA with (n  = 3) or without (n = 2) subtrochanteric shortening osteotomy (SSO) and secondary intramedullary femoral lengthening through a retrograde magnetically-driven lengthening nail (follow-up 18.4 (15–27) months). Results LLD was 51.0 (45–60) mm before and 37.0 (30–45) mm after THA. Delayed bone union at one SSO site healed after revision with autologous bone grafting and plate fixation. Subsequent lengthening led to leg length equalisation in all patients. Complete consolidation was documented in all lengthened segments. Conclusion Staged reconstruction via THA and secondary femoral lengthening can successfully be used to reconstruct the hip joint and equalise LLD. The specific anatomical conditions have to be taken into consideration when planning treatment, and patients ought to be closely monitored.

Staged Reconstruction

High voltage distribution network is an important link between transmission and middle voltage distribution network. If a high voltage distribution network fault occurs, the economy and reliability of the whole city distribution system will be seriously affected. To solve this problem, a traditional reconstruction optimization model is improved and a 2-staged reconstruction optimization model is proposed based on an improved particle swarm optimization (PSO) algorithm. The first stage reconstruction only considers the economic goal and the second stage reconstruction needs consider the boundary constrains. The 2-staged method considers the economic benefit and the voltage quality simultaneously. It can achieve the multi goals: meeting actual boundary operation conditions, optimizing the combination of network losses and the number of operation switching. The fault isolation and reconfiguration of an actual distribution network system in Dezhou power grid were simulated. Simulation results validate the rationality and feasibility of the proposed method

Restorative Surgery

Abstract Background Restorative surgery after colectomy due to ulcerative colitis (UC) may be performed simultaneously with colectomy (primary) or as a staged procedure. Risk factors for failure after restorative surgery are not fully explored. This study aimed to compare the risk of failure after primary and staged reconstruction. Methods This is a national register-based cohort study of all patients 15 to 69 years old in Sweden treated with colectomy due to UC and who received an ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) between 1997 and 2017. Failure was defined as a reoperation with new ileostomy after restorative surgery or a remaining defunctioning ileostomy after 2 years. Risk of failure was calculated using the Kaplan-Meier method and Cox regression adjusted for sex, age, calendar period, primary sclerosing cholangitis, and duration of UC. Results Of 2172 included patients, 843 (38.8%) underwent primary reconstruction, and 1329 (61.2%) staged reconstruction. Staged reconstruction was associated with a decreased risk of failure compared with primary reconstruction (hazard ratio, 0.73; 95% CI, 0.58–0.91). The 10-year cumulative risk of failure was 15% vs 20% after staged and primary reconstruction, respectively. In all, 1141 patients (52.5%) received an IPAA and 1031 (47.5%) an IRA. In stratified multivariable models, staged reconstruction was more successful than primary reconstruction in both IRA (hazard ratio, 0.75; 95% CI, 0.54–1.04) and IPAA (hazard ratio, 0.73; 95% CI, 0.52–1.01), although risk estimates failed to attain statistical significance. Conclusions In UC patients undergoing colectomy, postponing restorative surgery may decrease the risk of failure.
