Open Ankle Fractures: What Predicts Infection? A Multicenter Study.

OBJECTIVE: To identify the patient, injury, and treatment factors associated with an acute infection during the treatment of open ankle fractures in a large multicenter retrospective review. To evaluate the effect of infectious complications on the rates of nonunion, malunion, and loss of reduction. DESIGN: Multicenter retrospective review. SETTING: Sixteen trauma centers. PATIENTS: One thousand and 3 consecutive skeletally mature patients (514 men and 489 women) with open ankle fractures. MAIN OUTCOME MEASURES: Fracture-related infection (FRI) in open ankle fractures. RESULTS: The charts of 1003 consecutive patients were reviewed, and 712 patients (357 women and 355 men) had at least 12 weeks of clinical follow-up. Their average age was 50 years (range 16-96), and average BMI was 31; they sustained OTA/AO types 44A (12%), 44B (58%), and 44C (30%) open ankle fractures. The rate FRI rate was 15%. A multivariable regression analysis identified male sex, diabetes, smoking, immunosuppressant use, time to wound closure, and wound location as independent risk factors for infection. There were 77 cases of malunion, nonunion, loss of reduction, and/or implant failure; FRI was associated with higher rates of these complications (P = 0.01). CONCLUSIONS: Several patient, injury, and surgical factors were associated with FRI in the treatment of open ankle fractures. LEVEL OF EVIDENCE: Prognostic Level III.

Opioid-free shoulder arthroplasty: a prospective study of a novel clinical care pathway.

BACKGROUND: Opioid therapy has been a cornerstone of perioperative pain control for decades in the United States, despite our increased understanding of the morbidity and mortality linked to opioids. The purpose of this study is to explore the safety, efficacy, and feasibility of an entirely opioid-free perioperative pathway in patients undergoing elective shoulder arthroplasty. METHODS: Thirty-five patients undergoing elective total shoulder arthroplasty with a mean age of 71 (range, 50-87) years elected into a comprehensive opioid-free, multimodal pain management protocol. Opioid use was completely eliminated for all points in the perioperative period including during regional and general anesthesia. Data were collected regarding patient-reported pain, opioid consumption in the perioperative period, postoperative delirium, nausea, constipation, and falls. RESULTS: Pain level at the primary outcome point of 24 hours or discharge was rated at 2.5 on the numeric rating scale. Stable, low pain scores were demonstrated at all time points postoperatively. Low rates of nausea, falls, and constipation were reported. Only 1 patient required "rescue" opioid medications during the in-patient stay, and an additional patient was given a low-dose opioid prescription at the 2-week postoperative appointment. CONCLUSIONS: An opioid-free, multimodal pain management pathway is a safe and effective option in properly selected patients undergoing shoulder arthroplasty with a very low risk of requiring rescue opioids. This study is the first such study to present a surgical protocol entirely free of opioids at all portions of the patient care pathway.

Transtibial Versus Anteromedial Portal ACL Reconstruction: Is a Hybrid Approach the Best?

BACKGROUND: Improved biomechanical and clinical outcomes are seen when the femoral tunnels of the anterior cruciate ligament (ACL) are placed in the center of the femoral insertion. The transtibial (TT) technique has been shown to be less capable of this than an anteromedial (AM) portal approach but is more familiar to surgeons and less technically challenging. A hybrid transtibial (HTT) technique using medial portal guidance of a transtibial guide wire without knee hyperflexion may offer anatomic tunnel placement while maintaining the relative ease of a TT technique. PURPOSE: To evaluate the anatomic and biomechanical performance of the HTT technique compared with TT and AM approaches. STUDY DESIGN: Controlled laboratory study. METHODS: Thirty-six paired, fresh-frozen human knees were used. Twenty-four knees (12 pairs) underwent all 3 techniques (TT, AM, HTT) for femoral tunnel placement, with direct measurement of femoral insertional overlap and femoral tunnel length. The remaining 12 knees (6 pairs) underwent completed reconstructions to evaluate graft anisometry and tunnel orientation, with each technique performed in 4 specimens and tested using motion sensors with a quad-load induced model. Graft length changes and graft/femoral tunnel angle were measured at varying degrees of flexion. RESULTS: Percentage overlap of the femoral insertion averaged 37.0% ± 28.6% for TT, 93.9% ± 5.6% for HTT, and 79.7% ± 7.7% for AM, with HTT significantly greater than both TT (P = .007) and AM (P = .001) approaches. Graft length change during knee flexion (anisometry) was 30.1% for HTT, 12.8% for AM, and 8.5% for TT. When compared with the TT approach, HTT constructs exhibited comparable graft-femoral tunnel angulation (TT, 150° ± 3° vs HTT, 142° ± 2.3°; P < .001) and length (TT, 42.6 ± 2.8 mm vs HTT, 38.5 ± 2.0 mm; P = .12), while AM portal tunnels were significantly shorter (31.6 ± 1.6 mm; P = .001) and more angulated (121° ± 6.5°; P < .001). CONCLUSION: The HTT technique avoids hyperflexion and maintains femoral tunnel orientation and length, similar to the TT technique, but simultaneously achieves anatomic graft positioning. CLINICAL RELEVANCE: The HTT technique offers an anatomic alternative to an AM portal approach while maintaining the technical advantages of a traditional TT reconstruction.

Postoperative Complications Within the First Year After Extreme Lateral Interbody Fusion: Experience of the First 108 Patients.

STUDY DESIGN: Retrospective chart review. OBJECTIVE: To determine complications within the first year after undergoing extreme lateral interbody fusion (XLIF). SUMMARY OF BACKGROUND DATA: There are a growing but limited number of reports in the literature regarding early postoperative complications after XLIF. METHODS: We performed a retrospective chart review of perioperative complications of a case series of the first 108 patients to undergo XLIF at our institution between 2007 and 2009. We also recorded estimated blood loss, surgical time, and hospital length of stay for each procedure. RESULTS: There were 25 complications (23%) overall in patients who underwent the XLIF procedure. Four patients (3.7%) experienced major complications including: vertebral body fracture, contralateral nerve root injury, dense quadriceps paresis, and persistent stenosis. Three of these patients underwent revision surgery. There were 21 minor (19.4%) complications the vast majority of which consisted of approach-related thigh pain and/or paresthesias that all ultimately resolved. CONCLUSIONS: Transient ipsilateral thigh numbness, pain, and/or hip flexor weakness is a frequent postoperative finding most commonly when the L4-L5 level is instrumented. Dense femoral nerve palsy is a debilitating complication that may occur despite intraoperative neurophysiological monitoring. It should be noted that this retrospective study may underreport the true incidence of complications among these patients.

The utility of routine postoperative radiographs after cervical spine fusion.

BACKGROUND CONTEXT: The senior author (JAG) recently published an article questioning the utility of routine postoperative radiographs after lumbar spine fusion. That study concluded that routine postoperative radiographs in the presence of a normal physical examination rarely change the clinician's management of these patients. Our aim was to repeat this protocol in patients after cervical spine fusion. We hypothesized that routine postoperative radiographs are unnecessary in most cases after cervical spine fusion. PURPOSE: The purpose of this study was to determine the usefulness of routine postoperative cervical spine radiographs after cervical spine fusion as to whether they help to guide clinical decision making within the first postoperative year. STUDY DESIGN: This is a retrospective chart review of 383 patients who underwent a cervical spine fusion over a 5-year period. Seven different surgeons performed the cervical spine fusions. Our review assessed a total of 1,155 postoperative clinic visits. METHODS: Each clinical postoperative visit was reviewed. The history and exam were graded as either normal or abnormal, and any plain radiographs obtained were graded similarly as either normal or abnormal. Each patient's notes were followed up to 1 year postoperatively. Each patient had to have at least two postoperative visits with X-rays to be included in the study. We then noted any further action taken by the clinician based on the appearance of the radiograph in conjunction with the history and exam. RESULTS: In patients with normal history and exam presentations, further action was taken only 5/879 (0.57%) of the time, sometimes even in the presence of abnormal radiographs. The actions included two surgical revisions, two prolongations of cervical collar immobilization, and one patient who underwent a flexion/extension radiographic evaluation and subsequent prolonged cervical collar immobilization. There were 276 visits with abnormal history and exam; of these, 34/276 (12.3%) had abnormal X-rays. Of the clinic visits with abnormal history and exam and abnormal X-rays, 15/34 (44%) went on to revision. CONCLUSIONS: Routine postoperative radiographs after cervical spine fusion rarely appear to be of value when patients present with a normal history and exam and may expose patients to unnecessary diagnostic studies and expenses. Patients exhibiting a normal postoperative history and exam are likely to have no further additional action taken in the presence of either normal or abnormal radiographs.
