Anatomic study of the axillary nerve in a Chinese cadaveric population: correlation of the course of the nerve with proximal humeral fixation with intramedullary nail or external skeletal fixation.
The axillary nerve can be injured during external skeletal fixation with Schanz screws or proximal locking screws of intramedullary nails. Being aware of the axillary nerve's anatomic relationship to the proximal humerus is vital for avoiding complications. ⋯ Because of physical variability among individual patients and populations, surgeons should consider the possible courses of the axillary nerve when treating proximal humeral fractures.

Comparative StudyComparative study of percutaneous vertebroplasty and kyphoplasty in the treatment of osteoporotic vertebral compression fractures.
To compare the therapeutic effect of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (VCFs). ⋯ PVP and PKP have the ability of reducing pain in osteoporotic VCF patients. The correction of kyphotic deformity and restoration of the anterior vertebral body heights associated with osteoporotic VCFs was better in PKP.

Three kinds of forearm flaps for hand skin defects: experience of 65 cases.
Reverse radial forearm flap has been proven reliable and effective for hand reconstruction. Here we report our experience with the use of reverse forearm flap that does not contain the radial or ulnar artery for reconstruction of hand defects in 65 cases with soft tissue defects of the hand. ⋯ Our results indicated that the reverse forearm flap preserving the radial and ulnar artery is a reliable and effective method to cover skin defects of the hand.

ReviewSurgical options for reconstruction of the extensor mechanism of the knee after limb-sparing sarcoma surgery: an evidence-based review.
Limb-salvage surgery remains current best practice for management of soft tissue and bony sarcomas about the knee, with the range of reconstructive options all providing reassuring levels of long-term survival and function. There is no current consensus as to the best method of reconstruction of the extensor mechanism of the knee (quadriceps-patellar complex), with a wide variety of options proposed. The techniques described in the literature include prosthetic reconstruction, soft tissue reconstruction (comprising reconstruction with pedicled muscle flaps or autogenous tendon grafts), and bony reconstructions (including vascularised fibula flaps). An evidence-based literature review assessing the available reconstructive options has not been undertaken. ⋯ Given the proposed difficulties in randomising patients, good evidence for the optimal reconstructive choices may be hard to establish.

Case ReportsDynamization of locked plating on distal femur fracture.
Most of the clinical studies on the results of MIPO (minimally invasive plate osteosynthesis) with the use of anatomically preshaped locking plates for the complex distal femoral fractures have shown favorable results. In the application of bridge plating, placement of lag screws to the butterfly fragments is usually not recommended because it may make the whole construct too stiff. Recently, problems of nonunion related to excessive stiffness after MIPO using a locked plate were reported but the only solution suggested was reoperation with a bone graft. ⋯ It caused the situation of absolute stability with a significant gap to turn into the one of relative stability with acceptable gap. Fracture has solidly healed with bridging callus formation 6 months after lag screw removal under local anesthesia. We would like to call this strategy as "dynamization" of the locked plating.
