Concerns about blood loss and the safety of allogenic blood transfusion have led to the development of many transfusion options for lower extremity joint arthroplasty. Techniques for dealing with such blood loss include allogenic blood transfusion, autologous donation and transfusion, hemodilution, perioperative blood salvage, intraoperative cell savers, bipolar sealers, and pharmacological agents. A blood management strategy must consider both the patient and the surgical procedure, assess the transfusion risks, and formulate a plan to address them appropriately. ⋯ The purpose of this review is to report our opinion regarding the use of alternative blood management strategies and to discuss the possible advantages and disadvantages of each technique. The results of this review indicate that a patient-focused algorithm using one or more strategies such as preoperative administration of erythropoietin, preoperative autologous blood donation, use of a bipolar sealer, intraoperative blood collection and reinfusion, as well as postoperative reinfusion drains may reduce the need for allogenic blood transfusions in patients undergoing primary and revision lower-extremity joint arthroplasties. The authors believe that a patient-specific algorithm utilizing the aforementioned techniques can lead to a substantial decrease in morbidity and mortality and an overall cost saving for both patients and medical institutions.

Neurophysiological investigations and neurosurgical procedures of the sacral plexus are not especially well developed, because the sacral plexus is difficult to access. Awareness that sacral radiculopathies may exist is still lacking and the incidence of these pathologies is widely underestimated. ⋯ Regarding the dramatically increased incidence of sacral radiculopathies, especially secondary to pelvic prolaps surgeries by blind mesh-material implantation, this field of pathologies has to come in the focus of medical interests. Also, physicians involved in pelvic pathologies/surgeries have to be trained in clinical neuropelveology.

Lisfranc injuries are not very common. Surgical options available for treatment of Lisfranc injuries have produced chronic pain and disability due to the damage to the articular surface, leading to early arthritis. We describe the technique of extra-articular fixation using dorsal plates for Lisfranc injury, avoiding any damage to the articular surface.

Despite the advancement of surgical techniques in endoscopic spine surgeries, treatment of central and paracentral disc herniations, especially disc extrusions and disc sequestrations, remains challenging. On the basis of our experience with treating disc tears, disc herniations, and other spinal diseases, we have developed a new technique we call the "between" technique. This technique involves positioning the opening of the endoscope access cannula at the edge of the targeted disc with half of the opening being positioned inside the disc and the other half positioned in the epidural space. ⋯ The technique is safe, effective, and easy to use. It has been proven particularly efficacious for the treatment of central and paracentral extruded disc herniations and sequestered disc herniations. The purpose of this Chapter is to describe this technique and introduce its application in removing central and paracentral disc extrusions and sequestrations.

Brain tissue retraction is frequently required to reach deep intra-axial lesions, and the quest for an ideal retractor that would protect the underlying brain tissue continues. Despite the availability of multiple retractors, the incidence of brain retraction injury remains high and has been reported to be 5% to 10%. A recently developed transparent tubular retractor appears to provide several advantages in surgery for deep intra-axial tumors and intracerebral hematomas. ⋯ Transparent tubular retractors provide a unique means of deep visualization and even force distribution at the retracted brain tissue. Although these retractors were originally designed for the removal of deep subcortical tumors, they may be used to access and evacuate intracerebral hematomas. In our experience, the use of tubular retractors allows one to achieve safe access to deep intracerebral lesions and decreases the rate of retraction-related complications.
