We used decision analysis to assess the cost profile associated with preoperative use of tranexamic acid (TXA) to prevent major bleeding complications associated with hip and knee arthroplasty surgery. We defined major bleeding complications as blood loss sufficient to require transfusion or surgical evacuation of a postoperative hematoma. ⋯ For centers with baseline transfusion rates above 25%, however, TXA becomes increasingly cost-saving as the reduction in transfusion rates seen with use of the drug increases, but a minimum 12% reduction in transfusion rates is needed, even if the expected baseline transfusion rate is 100%. Nevertheless, TXA use is much more likely to be cost-saving, regardless of transfusion rates, if it leads to a reduction in need for revision surgery.

Case Reports
Lateral femoral cutaneous nerve palsy following shoulder surgery in the beach chair position: a report of 4 cases.
Neuropathy of the lateral femoral cutaneous nerve can present as pain, decreased sensation, and/or burning or tingling on the anterolateral thigh. We present 4 cases of lateral femoral cutaneous nerve palsy following shoulder surgery in the beach chair position, all of which occurred in obese patients. ⋯ Full resolution of symptoms can be expected within 6 months following conservative management. A preoperative discussion regarding this complication should occur with obese patients undergoing shoulder surgery in the beach chair position.

Coccidioidomycosis infections result from inhalation of the dimorphic fungus Coccidiodes immitis. Coccidioidomycosis typically is benign, but its extremely rare disseminated form can result in significant morbidity and mortality. Dissemination of the fungus to the spine is difficult to control and usually requires an aggressive combination approach (surgical/medical). ⋯ The patient presented with an unstable C5 pathologic fracture caused by C immitis. After corpectomy and stabilization of the cervical spine along with antifungal therapy with amphotericin B and oral fluconazole, he developed multiple complications. This case illustrates some of the potential pitfalls in managing spinal osteomyelitis caused by C immitis and the need for continuous medical therapy after surgical treatment.

The majority of patients with symptomatic herniated discs can be successfully and conservatively managed and can achieve clinical improvement without surgical intervention. Resorption of the herniated nucleus pulposus (HNP) is 1 conservative mechanism for clinical improvement. We present the case of a 76-year-old healthy man with acute cervical radicular right arm pain and positive Spurling test. ⋯ The patient returned to his normal activities and has not had recurrence of symptoms for 2 years. This report provides an interesting example of complete resorption of a large, extruded cervical herniated disc in a symptomatic patient and a review of the literature on resorption of herniated discs. The review suggests that larger herniations with an epidural location (penetration of the posterior longitudinal ligament) have a greater chance of resorption.

Because the spine and pelvis are integrated, changes in spine sagittal balance affect relative acetabulum position. A 1° change of the anterior pelvic plane changes acetabulum anteversion by 0.8°. Three-column spine osteotomies correct fixed sagittal plane deformity. ⋯ This correction of the sagittal balance is associated with a concomitant increase in sacral slope, pelvic tilt, and the anterior pelvic plane angles. These changes will increase acetabulum anteversion by a predicted 6.54°. This increase will change acetabular cup position and must be considered in patients with spine and pelvic osteoarthritis that requires hip surgery.
