Purpose: To report the radiological outcomes and complications of the Masquelet induced membrane technique (IMT) for acute bone reconstruction in complex hand injuries.
Methods: We retrospectively reviewed 22 patients treated primarily by the IMT for bone defect of the phalanx and/or metacarpals bones in 26 injured digits. The median bone defect length was 17 mm (IQR 13-25). Given the severity and variability of the lesions, revision parameters focused on bone healing and postoperative complications.
Results: At the median follow-up of nine months (IQR, 6-14 months), bone union was achieved in 25 digits (96%) with a median delay of three months (IQR, 2.5-3.5 months) after stage 2. Postoperative complications occurred in 11 of 26 digits requiring revision surgery in nine of 26 digits (35%). Soft tissue coverage failure and infection were the main complications. A patient underwent a late amputation through the metacarpophalangeal joint due to an uncontrolled bone infection.
Conclusions: Despite a significant rate of complications, bone reconstruction using the IMT is a reliable procedure for achieving bone healing of phalanx or metacarpal bone defects in complex hand injuries.

Objectives: To develop a platform including a deep convolutional neural network (DCNN) for automatic segmentation of the maxillary sinus (MS) and adjacent structures, and automatic algorithms for measuring 3-dimensional (3D) clinical parameters.
Materials And Methods: 175 CBCTs containing 242 MS were used as the training, validating and testing datasets at the ratio of 7:1:2. The datasets contained healthy MS and MS with mild (2-4 mm), moderate (4-10 mm) and severe (10- mm) mucosal thickening.

Introduction: Knee alignment significantly impacts the outcome of total knee arthroplasty (TKA). Understanding patient perceptions of their knee alignment in relation to objective measurements is essential to ensure optimal surgical outcomes and to meet patients' expectations. This study reports patients' perception of pre- and postoperative knee alignment in relation to radiographic alignment measurements.

Introduction: Intensive research is dedicated to the development of novel biomaterials and medical devices to be used as grafts in reconstructive surgery, with the purpose of enhancing their therapeutic effectiveness, safety, and durability. A variety of biomaterials, from autologous bone to polymethylmetacrylate, polyether ether ketone, titanium, and calcium-based ceramics are used in cranioplasty. Porous hydroxyapatite (PHA) is reported as a possible material for bone reconstruction, with good signs of biocompatibility, osteoconductive and osteointegrative properties.

To evaluate the drug release, cytocompatibility with periodontal ligament cells (PDLCs), and therapeutic efficacy of GelMA hydrogel loaded with resolvin D1 (RvD1) in treating rat periodontal inflammation and alveolar bone damage. An RvD1 complexed with GelMA was prepared, and its release kinetics and compatibility with PDLCs were assessed. Rats with induced periodontitis were treated weekly with topical applications of vehicle, GelMA, RvD1, or RvD1 complexed with GelMA for four weeks.

Our aim was to validate a sacral-mounted inertial measurement unit (IMU) for reconstructing running kinematics and comparing movement patterns within and between runners. IMU data were processed using Kalman and complementary filters separately. RMSE and Bland-Altman analysis assessed the validity of each filtering method against a motion capture system.
