Options for the treatment of proximal- and middle-thirds of humeral shaft fractures include intramedullary interlocking nail (IMN) and minimally invasive plate osteosynthesis (MIPO). However, whether IMN provides better clinical outcomes than MIPO surgical technique still remains unclear. This study was designed to compare clinical outcomes of the IMN with MIPO technique for the treatment of proximal- and middle-thirds of humeral shaft fractures. ⋯ Intramedullary interlocking nail seemed to be superior to minimally invasive plate osteosynthesis in the treatment of proximal- and middle-thirds of humeral shaft fractures due to shorter operative time and union time, less early post-operative pain, and fewer complications. The intramedullary interlocking nail could be considered a better surgical option for the management of proximal middle humeral fractures, though it may also depend on the surgeons' skills and learning curve. Further in-depth prospective studies are in great need to verify our conclusion.

This study aimed to evaluate the safety and efficacy of fusiform capsulectomy of posterior capsule in correcting severe flexion contracture during total knee arthroplasty (TKA). ⋯ The technique of fusiform capsulectomy of posterior capsule to correct the severe flexion contracture during primary TKA is safe and effective and could provide good short-term results.

The accuracy of robot-assisted pedicle screw implantation is a safe and effective method in lumbar surgery, but it still remains controversial in lumbar revision surgery. This study evaluated the clinical safety and accuracy of robot-assisted versus freehand pedicle screw implantation in lumbar revision surgery. ⋯ Compared with freehand screw implantation, in lumbar revision surgery, the Renaissance robot had higher accuracy and safety of pedicle screw implantation, fewer superior level facet joint violations, and less intra-operative blood loss and intra-operative fluoroscopy time.

Stromal vascular fraction (SVF) as an injectable regenerative therapy for knee osteoarthritis (OA) has gained recent popularity. However, there is no clear consensus on the outcomes of such treatment. We systematically reviewed available evidence on the use of SVF injection in the treatment of knee OA. ⋯ Intra-articular injection of SVF is a safe and effective technique for the management of knee OA. However, comparative Level I studies are needed to support the use of adjuvants with SVF and also to compare the use of SVF (with or without adjuvants) with ADMSCs, PRP, and bone marrow concentrate.

Randomized Controlled Trial
Short and long-arm fiberglass cast immobilization for displaced distal forearm fractures in children: a randomized controlled trial.
The aim of this study was to investigate whether short-arm fiberglass cast (SAC) immobilization provides fracture stabilization comparable to that of long-arm cast (LAC) treatment of displaced distal forearm fractures after closed reduction in paediatric patients. ⋯ Fracture immobilization with short-arm fiberglass cast in reduced distal forearm fractures is not inferior to long-arm casts in children four years and older, excluding completely displaced fractures. Furthermore, short-arm casting reduces the need for assistance during showering.
