SUMMARY: This novel hybrid single-double-single barrel (1-2-1) design for fibula free flap reconstruction addresses the unique challenges presented by Brown Class III mandibular defects, which involve long-span defects at both bodies of mandible and chin. The importance this lies in its ability to overcome limitations traditional approaches terms height pedicle length, while optimizing functional esthetic outcomes. technique utilizes a combination segments achieve ideal esthetics support...

Abstract Background Computer-assisted surgery has transformed the approach to jaw resection and reconstruction in recent years. However, extensive time technical expertise needed for planning creation of patient-specific implants guides have posed significant challenges many surgeons field. This study introduces a novel algorithm designed streamline traditionally intricate time-consuming Computer-Aided Design (CAD) process developing (PSIs). Methods The requires three-dimensional (3D) model...

Background: Computer-assisted surgery in head and neck reconstruction yields predictable favorable clinical outcomes. However, there is a lack the optimal arrangement of fibula bone segments to re-establish function aesthetics maxilla. Methods: This study proposed novel anatomical landmark-guided strategy for virtual surgical planning (VSP) infrastructure maxilla using free flap. The positioning was validated with retrospective study. Patients who underwent computer-assisted maxillectomy...

To summarize the clinical results of femoral head fracture-dislocation treated according to Pipkin classification.Atotal 19 patients with were retrospectively analyzed from Mar. 2008 2015. According classification criteria, there 4 cases in Type-I, 6 Type-II, Type-IIIand 3 Type-IV. Various procedures taken different types fracture, time and age patients. X-ray was examined during follow-up period functional evaluation carried out by Harris Hip Score's criteria. The therapeutic effects...

Objective To discuss the operative methods and curative effect of calcaneal tuberosity fracture. Methods A retrospective study was done to analyze 15 patients with fracture who received surgical management between J anuary 2008 une 2011. There were nine males six females, age ranging from 31 68 years (average, 51.4 years). All had unilateral acute injury, left foot in 7 cases right 8 cases. According B eavis classification, there three type I 12 II . 10 treated open reduction screw fixation....

Objective . To evaluate the stress status of fracture site caused by femoral neck shortening and to analyze implants from finite element point view. Methods CT scan data hip a normal adult female were collected. Three‐dimensional reconstruction MICs related module function simulation was used establish postoperative model with Pauwels angle > 50 ° , which treated cannulated screws. The models divided into four groups: neck, in 2.5 mm, 7.5 12.5 mm. analysis software msc.nastran2012 used,...

Objective: To evaluate the stress status of femoral head and neck, screws acetabulum caused by neck shortening after internal fixation fracture with finite element method, to analyze proximal from mechanical point view. Methods: CT scan data hip a healthy adult female were collected. Three-dimensional reconstruction MICs related module function simulation was used establish postoperative model Pauwells angle>50°, which treated cannulated screws. The models divided into four groups: normal...

Purple sweet potato pigment is a natural food pigment, the stability important to its quality assurance. The effects of metal ions on purple were investigated. results showed that Mg2+and Fe3+ conductive pigments in initial storage, and with concentration increased, was more stable. But K+, Ca2+, Na+, Cu2+, Mg2+ had brought color density, intensity preservation rate down long-term storage.

Objective: To summarize the functional outcome of tarsometatarsal joint fracture-dislocation managed according to Myerson classification.Methods: Total eighty cases were treated from Mar 2004 Feb 2012. According classification, there 14 in type A, 12 B1, 28 B2, 11 C1 and 15 C2. All with open reduction internal fixation incisions implants also selected classification. X-ray was examined during follow-up period evaluation carried out by American Orthopaedic Foot Ankle Society (AOFAS) midfoot...

Objective To evaluate our self-designed director for sustentaculum tali screwing used to fixate intra-articular calcaneal fractures in comparison with a conventional director. Methods From May 2012 October 2013, total of 40 patients received surgical treatment fracture at department. Our was 20 them (24 feet, group A) while the other (22 B). The 2 groups were compatible preoperative clinical data, showing no significant differences (P>0.05). operation time, fluoroscopy frequency, rate...

Blooms of the Microcystis aeruginosa in water have been a long-standing problem for quality and human-health issue. Public concern inhibition has become increasingly urgent. AgBiO 3 is an algaecide having good inhibitory effects on growth with hydroxyl radicals generated by photocatalyst. The exposed to was optimised using statistically-based experimental designs. four variables, namely, ZnSO 4 , CaCl 2 CuSO NaNO were screened as significant further determine optimum levels their...

Objective To explore the necessity and function of sustentaculum tali screw placement for treatment Sanders type Ⅱ calcaneal fracture.Methods The data Dicom that CT scan with bone was input into Mimics 12.0 software Ansys 13.0 construction calcaneus three-dimensional finite element model.Then,this model imported Solidworks 2010 software.Type fracture established according to cutting calcaneus.Geometric parameters AO plate screws were software.Two internal fixation simulations based on...

In order to select the proper size of prosthesis ball head, biomechanical changes hip joint using different diameter head was studied by three-dimensional finite element analysis.The thin-layer CT data and related parameters artificial femoral were used establish model after replacement with prosthesis(M0:preoperative model;M1:ball diameter=original diameter;M2:ball diameter+1 mm;M3:Ball diameter= Original -1 mm;M4:ball =original -2 mm). Loading forces muscle loads loaded, stress...

To compare the effectiveness of anterior subcutaneous pelvic internal fixator (INFIX) and plate fixation in treatment unstable ring fractures.The clinical data 48 patients with fractures who met selection criteria between June 2014 December 2019 were retrospectively analyzed. Among them, 21 cases treated INFIX (INFIX group), 27 (plate group). There was no significant difference gender, age, body mass index, cause injury, time from injury to operation, Injury Severity Score (ISS), fracture...

Objective:To analyze the clinical features of juvenile ossifying fibroma in nasal root and to compare different surgical methods.
