Introduction: Postoperative delirium is associated with opioid use in the elderly and is a common complication of geriatric hip fractures, with reported incidences from 16% to 70%. Intravenous (IV) acetaminophen is a safe and efficacious medication in elderly patients and has been shown to reduce use of opioids after hip fracture. At our institution, IV acetaminophen was implemented for the first 24 hours postoperatively as part of a multimodal pain control regimen for geriatric hip fracture patients. Methods: A retrospective review of 123 hip fragility fracture patients older than 60 years from January 2016 to December 2016 was performed. Delirium was identified using a validated chart–based review tool. The rate of delirium, as well as length of stay, pain scores, opioid administration, need for one-to-one supervision, and readmissions were analyzed. Results: Sixty-five patients (52.8%) received IV acetaminophen during this period. No notable differences were found in baseline characteristics between groups. Ten of 65 patients receiving IV acetaminophen postoperatively experienced delirium compared with 19 of 58 who did not receive the medication (15.4% versus 32.8%, P = 0.024). The IV acetaminophen group also required fewer doses of IV opioids on postoperative day 1 (0.37 versus 1.19 doses, P = 0.008), were less likely to require one-to-one supervision (9.2% versus 24.1%, P = 0.025), and had shorter lengths of hospital stay (6.37 versus 8.47 days, P = 0.037). Readmission rates and discharge dispositions did not vary with significance between the two groups. Conclusion: The inclusion of IV acetaminophen as part of a multimodal pain regimen led to fewer episodes of delirium in this study. The reduced use of opioids immediately after surgery may have been a large factor in this outcome. Lower delirium rates may reduce the utilization of inpatient resources for direct patient supervision and provide for shorter hospital stays.

Direct anterior total hip arthroplasty has become increasingly more popular among arthroplasty surgeons, in large part due to the use of an intramuscular interval and desire to reduce soft tissue damage. Several studies have now been published comparing the anterior intramuscular to other commonly used approaches, and many studies have published complication rates on large series of patients. Review of comparative studies indicates direct anterior hips tend towards shorter hospital stays and high rates of patients discharged to home. Although some studies show evidence of early benefit in functional outcomes, there is no strong evidence that the anterior approach provides any long term functional improvements compared to other approaches. Additionally, evidence to support reduced damage to soft tissue may not translate to certain clinical significance. Rates of intra-operative femur fracture, operative time and blood loss rates are notably higher for those developing familiarity with this approach. However, when surgeons have performed a modest number of procedures, the complication rates tend to markedly decrease in most studies to levels comparable to other approaches. Accuracy of component positioning also favors the anterior approach in some studies. This review summarizes the available literature comparing the direct anterior to other approaches for total hip arthroplasty and provides a comprehensive summary of common complications.

Our results demonstrate a low sensitivity and high specificity in the diagnosis of Type-II SLAP lesions with noncontrast MRI in this community setting. Musculoskeletal fellowship-trained radiologists had significantly higher sensitivities in accurately diagnosing the lesion than did radiologists without such training. Noncontrast MRI is not a reliable diagnostic tool for Type-II SLAP lesions in a community setting.

The direct anterior approach to the hip has been suggested to have several advantages compared to previously popular approaches through its use of an intra-muscular and intra-nervous interval between the tensor fasciae latae and sartorius muscles. Recent increased interest in tissue-sparing and minimally-invasive arthroplasty has given rise to a sharp increase in the utilization of direct anterior total hip arthroplasty. A number of variations of the procedure have been described and several authors have published their experiences and feedback to successfully accomplishing this procedure. Additionally, improved understanding of relevant soft tissue constraints and anatomic variants has provided improved margin of safety for patients. The procedure may be performed using specially-designed instruments and a fracture table, however many authors have also described equally efficacious performance using a regular table and standard arthroplasty tools. The capacity to utilize fluoroscopy intra-operatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons gaining familiarity. Proper management of patient and limb positioning are vital to reducing risk of intra-operative complications. An understanding of its limitations and challenges are also critical to safe employment. This review summarizes the key features of the direct anterior approach for total hip arthroplasty as an aid to improving the understanding of this important and effective method for modern hip replacement surgeons.

Background Although gunshot injuries are relatively common, there is little consensus about whether retained bullets or bullet fragments should be removed routinely or only in selected circumstances. Questions/purposes We performed a systematic review of the literature to answer the following questions: (1) Is bullet and/or bullet fragment removal from gunshot injuries to the pelvis or extremities routinely indicated? And, if not, (2) what are the selected indications for removal of bullets and/or bullet fragments? Methods A search of the English-language literature on the topic of gunshot injury and bullet removal was performed using the National Library of Medicine and MEDLINE 1 and supplemented by hand searching of bibliographies of included references. Studies were included if they provided clinical data on one or both of our study questions; included studies were evaluated using the levels of evidence rubric. Most studies on the subject were expert opinion (Level V evidence), and these were excluded; one Level III study and seven Level IV studies were included.Results No studies provided a rationale for routine bullet removal in all cases. The studies identified bullet fragment removal as indicated acutely for those located within a joint, the palm, or the sole. Chronic infection, persistent pain at the bullet site, and lead intoxication were reported as late indications for bullet removal. Conclusions The evidence base for making clinical recommendations on the topic of bullet and bullet fragment removal after gunshot injury is weak. Level I and II evidence is needed to determine the indications for bullet removal after gunshot injury.

Pain after total knee arthroplasty (TKA) is not infrequent and may be indicative of a broad spectrum of prosthesis-related, intra-articular, or extra-articular pathologies. To diagnose and treat the underlying cause of a painful TKA, systematic evaluation of the patient is critical to ensure that they are managed appropriately and expeditiously. This evidence-based review presents current concepts regarding the pathophysiology, etiology, and diagnosis of painful TKA and our recommended approach for management.
