Objective: To investigate the effectiveness of three-dimensional strapping reduction in treatment of patellar fracture.
Methods: Between January 2015 and June 2015, thirty-two patients were randomly allocated to three-dimensional strapping reduction group (trial group) and towel clamp reduction group (control group). There was no significant difference in age, gender, damage side, interval from injury to opreration, fracture pattern, and cause of injury ( >0.05). The operation time, fluoroscopy time, fracture healing time, postoperative Hospital for Special Surgery (HSS) scores, and complications were collected and analysed.
Results: All incisions healed at stage I. All patients of 2 groups were followed up 10-14 months (mean, 12.4 months). The operation time and fluoroscopy time of trial group were both shorter than those of control group ( =6.212, =0.000; =6.585, =0.000). X-ray films showed that the fractures in both groups healed successfully and there was no significant difference in healing time between groups ( =1.973, =0.058). Bone nonunion, infection, and failure fixation were not found in both groups. HSS scores of trial group (91.6±3.8) was higher than that of control group (86.4±5.5) ( =-3.105, =0.004).
Conclusion: Compared with towel clamp reduction, the three-dimensional strapping reduction in treatment of patellar fracture has the advantages of shorter operation time and fluoroscopy time, better knee function after operation, and satisfactory fracture healing.

Background: Tracheal implants using tissue engineering and 3-dimensional printing are promising, but challenges remain, including graft composition, anastomosis methods, and tracheal tissue regeneration. This study examined the effectiveness of various tracheal graft materials in a large animal model.
Methods: A total of 38 operations were performed on a porcine large animal model, involving a 2-cm circumferential tracheal excision with end-to-end anastomosis.

Objectives: To compare the adaptation of maxillary removable partial denture (RPD) frameworks fabricated through direct digital workflows with that of traditional cast frameworks and indirect digital frameworks.
Methods: The workflow for fabricating the digital cobalt-chromium framework encompassed intraoral scanning (IOS) using Trios 3, computer-aided survey and design, and subsequently either the lost-wax technique from a printed resin framework pattern (Framework B) or direct selective laser melting (SLM) (Framework C). The traditional cast framework (Framework A) was selected as a control.

Osmotic pump systems require prolonged retention time in the stomach to provide enhanced bioavailability and regulated release, which is quite challenging. This study used a three-dimensional printing (3DP) technique combined with a gastro-retentive floating device (GRFD) to extend the retention of the osmotic pump in the stomach and enhance its bioavailability. The strap-on buoyant device was fabricated by stereolithography 3DP and incorporated a felodipine osmotic pump tablet used in clinical practice, which enabled it to float in the stomach or dissolution media without any floating lag time.

Polycaprolactone (PCL) implants in large animals show great promise for tracheal transplantation. However, the longest survival time achieved to date is only about three weeks. To meet clinical application standards, it is essential to extend the survival time and ensure the complete integration and functionality of the implant.
