Objective: To study the role of transplantation of the vascularized pedicle iliac crest for the repair of bone and soft tissue defect of lower extremity.
Methods: The vascularized pedicle iliac crest was designed for the repair of bone and soft tissue defect of lower extremity according to anatomic feature of leg and foot. Skin graft was used for coverage of the iliac flap.
Results: Skin survival could demonstrate the survival of the vascularized pedicle iliac crest indirectly one week postoperatively. Skin survived completely in 4 cases and partly in 3 cases. Callus was seen at the transplantation site one month postoperatively, and K-wires were removed 4 months later in the cases of metatarsal defect. The external fixators were removed in the cases of tibia defect 6 to 8 months postoperatively. The functions of lower extremities were restored in 2 to 4 months. The bone and soft tissue defects were repaired, and ultimate function and cosmetic effects were satisfied after the mean follow up of 10 months (ranged from 6 to 15 months).
Conclusion: Transplantation of the vascularized pedicle iliac crest is an ideal method for the repair of bone and soft tissue defect of lower extremity. The operation can be performed in one stage. The functions and cosmetic effects are better than the traditional methods.

Background Context: 3D-printed titanium cage designs can incorporate complex, porous features for bone ingrowth and a greater surface area for minimizing subsidence. In a companion study (Part 1), we determined that increased surface area leads to decreased subsidence; however, it remains unclear how increasing the cage surface area, resulting in a smaller graft aperture, influences fusion.
Purpose: We evaluated the effects of surface area of 3D-printed titanium cages and the use of autologous bone grafts on spinal fusion in sheep.

Article Synopsis
- Robotic-assisted spine surgery enhances the precision and safety of procedures like pedicle screw placement, minimizing blood loss and reducing hospital stays while alleviating postoperative pain.
- Recent advancements allow robotic systems to perform not only screw insertion but also critical tasks like surgical decompression and bone preparation, transitioning from experimental models to actual human applications.
- The Mazor X Stealth Edition Spine Robotic System facilitates these procedures by combining advanced software for planning and real-time imaging, leading to more efficient and accurate minimally invasive transforaminal lumbar interbody fusion (MI-TLIF).

Optimal reconstruction of weight-bearing plantar foot defects is challenging due to the need for relatively thin coverage with simultaneous durability. The medial plantar flap provides an excellent tissue match but is not always available or appropriate (Figure 1, 2). Microsurgical free flap reconstruction provides many options for coverage.

Genital lymphedema is a challenging condition often refractory to conservative treatments. This case report presents a novel surgical approach combining a lymphatic system transfer based on a pedicled superficial circumflex iliac perforator flap with nanofibrillar collagen scaffolds to address genital lymphedema secondary to hidradenitis suppurativa. A 47-year-old man with hidradenitis suppurativa-related genital lymphedema, unresponsive to conservative measures, underwent the procedure.
