Randomized Controlled Trial
Is it really necessary to perform venous anastomosis in vascularized corticoperiosteal bone flap? A randomized prospective 4-year follow-up study.
This study aims to investigate the treatment results of atrophic nonunion of the lower and upper limb with vascularized bone flaps performed with only arterial anastomosis versus the execution of flaps performed with arterial and venous anastomosis, comparing the surgical time and the healing rate of these two techniques. ⋯ Our investigation suggests that it isn't necessary to perform the venous anastomosis between the flap pedicle and the recipient area. Presumably, the venous blood flow reaches the systemic circulation through the vascular bone marrow network. Our procedure avoids venous trauma during the dissection and execution of the anastomosis and, therefore, can minimize complications such as venous thrombosis.

Hybrid screw fixation for femoral neck fractures: Does it prevent mechanical failure?
Traditionally, femoral neck fracture fixation has been performed using three partially threaded cancellous screws. However, fracture collapse with femoral neck shortening, and varus deformation frequently occurs due to posterior medial comminution and lack of calcar support. We hypothesize replacing the inferior neck/calcar screw with a fully threaded, length stable, screw will provide improved biomechanical stability, decrease femoral neck shortening and varus collapse. ⋯ Our study is the first to assess the biomechanical effects of hybrid fixation for femoral neck fractures. Hybrid screw configuration resulted in significantly stronger constructs, with higher axial load and increased cycles prior to failure. The advantageous mechanical properties demonstrated using a fully threaded inferior calcar screw provides a length stable construct which may prevent the common complication of excessive femoral neck shortening, varus collapse and poor functional outcome.

Application of optimized three-dimensional digital surgical guide plates for complex midfacial fractures.
The treatment of midfacial fractures is always difficult. The purpose of this study was to verify whether optimized three-dimensional (3D) digital surgical guide plates combined with preformed titanium plates improved the treatment effect in complex midfacial fractures. ⋯ Optimized 3D digital guide plates can accurately locate preformed titanium plates and effectively improve the treatment effect in complex midfacial fractures.

Single intra-articular injection with or without intra-osseous injections of platelet-rich plasma in the treatment of osteoarthritis knee: A single-blind, randomized clinical trial.
Subchondral bony structure damage plays an essential role in the pathogenesis of osteoarthritis (OA) knee. An intra-articular injection cannot reach the damaged subchondral bony structure and treat its pathologies effectively. The objective of the study was to compare the clinical effects of single intra-articular injection with or without intra-osseous injections of PRP in the treatment of osteoarthritis (OA) knee. ⋯ Both groups showed significant improvement following the intervention. Intra-osseous PRP injections did not provide any additional benefit over intra-articular PRP injection until six months regarding pain relief and functional improvement.
