ABSTRACT

BACKGROUND: Total elbow arthroplasty (TEA) is uncommon, but growing in incidence. Traditionally an inpatient operation, a growing number are performed outpatient, consistent with general trends in orthopedic surgery. The aim of this study was to compare TEA outcomes between inpatient and outpatient surgical settings. Secondarily, we sought to identify patient characteristics that predict the operative setting. METHODS: Patient data were collected from the American College of Surgeons National Quality Improvement Program. Preoperative variables, including patient demographics and comorbidities, were recorded, and baseline differences were assessed via multivariate regression to predict operative setting. Multivariate regression was also used to compare postoperative complications within 30 days. RESULTS: A total of 468 patients, 303 inpatient and 165 outpatient procedures, were identified for inclusion. Hypoalbuminemia (odds ratio [OR], 2.5; P=0.029), history of chronic obstructive pulmonary disorder or pneumonia (OR, 2.4; P=0.029), and diabetes mellitus (OR, 2.5; P=0.001) were significantly associated with inpatient TEA, as were greater odds of any complication (OR, 4.1; P<0.001) or adverse discharge (OR, 4.5; P<0.001) and decreased odds of reoperation (OR, 0.4; P=0.037). CONCLUSIONS: Patients undergoing inpatient TEA are generally more comorbid, and inpatient surgery is associated with greater odds of complications and adverse discharge. However, we found higher rates of reoperation in outpatient TEA. Our findings suggest outpatient TEA is safe, although patients with a higher comorbidity burden may require inpatient surgery. Level of evidence: III.

ABSTRACT

BACKGROUND: Decision making in the management of proximal humerus fractures can be difficult in situations in which the surgeon is uncertain of the ideal treatment. METHODS: Two shoulder surgeons operatively treated 476 proximal humerus fractures from 1998-2014 with open reduction-internal fixation (ORIF), hemiarthroplasty, or reverse shoulder arthroplasty. Operative treatment was stratified by year to determine the evolution of technological influences on treatment over time. To evaluate the effect of uncertainty, 274 clinical vignettes were created for all patients with 1 year of follow-up or more and reviewed by 3 fellowship-trained shoulder surgeons to determine the type of treatment for each case. To evaluate the effect of certainty, range of motion for each patient with unanimous agreement on treatment was analyzed. RESULTS: ORIF treatment increased from 40% to 62% after release of the proximal humerus locking plate. Introduction of the fracture stem in 2011 increased reverse shoulder arthroplasty for fractures from 8.8% to 44.3%. Unanimous agreement on either operative or nonoperative treatment occurred 70.5% of the time. Only 63.5% of patients received the actual treatment selected (P = .001). Patients for whom unanimous agreement matched actual treatment in the ORIF treatment group showed improvement of forward elevation (144° vs 123°, P = .005) and abduction (129° vs 103°, P = .002). CONCLUSION: Successful management of displaced proximal humerus fractures requires both technical and decision-making abilities. The difficulty in making these decisions is reflected by the agreement of experienced shoulder surgeons only 63.5% of the time regarding the treatment performed. When uncertainty occurs, patients may have reduced outcomes as seen in the ORIF treatment group.

ABSTRACT

PURPOSE OF REVIEW: The purpose of this review is to discuss the indications for reverse shoulder arthroplasty (RSA) in the treatment of massive rotator cuff tear (MCT), review the reported outcomes in the literature, and outline our approach and surgical technique for treating these patients. RECENT FINDINGS: While RSA remains a successful and well-accepted treatment for cuff tear arthropathy (CTA), management of MCT in the absence of arthritis is controversial. In this particular setting, patients best suited for RSA are elderly, lower-demand individuals with chronic, irreparable MCT, and pseudoparalysis. Age < 60, better pre-operative function and upper extremity neurologic dysfunction are potential risk factors for poor outcome with RSA in this population. Long-term follow-up studies of RSA for CTA and MCT show good functional outcomes and implant survival > 90% at 10 years. Treatment of MCT must be individualized for each patient. When patient selection is optimized, RSA is a reliable means of relieving pain and improving function with excellent success. Further investigation is necessary to better define its indications and assess the role of alternative, joint-salvaging procedures.

ABSTRACT

BACKGROUND: This study evaluated the effect of cystic changes in the glenoid on postoperative outcomes and implant survival after total shoulder arthroplasty (TSA). MATERIALS AND METHODS: From 2004 to 2012, 75 patients underwent TSA for primary osteoarthritis with minimum 5-year follow-up. Preoperative 3-dimensional models based on computed tomography imaging were created for all patients. A qualitative evaluation of cystic osteoarthritis was performed through survey grading by 3 fellowship-trained shoulder surgeons. The extent of cyst formation in the glenoid (no cysts, small, medium, or large) was assigned for every patient. In addition, quantitative evaluation was performed on 3-dimensional glenoid models. Functional outcomes, radiographic findings, and the need for revision were compared between group 1 (large and medium cysts) and group 2 (small and no cysts). RESULTS: Qualitative evaluation of cyst formation resulted in the following distribution: no cysts in 8 patients (11%), small cyst formation in 27 (36%), medium cysts in 19 (25%), and large cysts in 21 patients (28%; κ = 0.605). The difference in total cyst volume between group 1 and group 2 was significant (P = .004). The overall revision rate was 7% (5 of 75). All revised patients were in the groups with medium or large cysts. There were no statistical differences in American Shoulder and Elbow Surgeons (ASES) Standardized Shoulder Assessment scores or presence of radiographic loosening among the study groups. CONCLUSION: Qualitative computed tomography evaluation of cystic osteoarthritis correlates with quantitative analysis of cyst volume. Severe cyst formation portends a higher risk of failure at midterm follow-up. Cystic disease did not affect functional outcome or the presence of radiographic glenoid loosening.

ABSTRACT

BACKGROUND: Revision of unstable reverse shoulder arthroplasty (RSA) remains a significant challenge. The purpose of this study was to determine the reliability of a new treatment-guiding classification for instability after RSA, to describe the clinical outcomes of patients stabilized operatively, and to identify those with higher risk of recurrence. METHODS: All patients undergoing revision for instability after RSA were identified at our institution. Demographic, clinical, radiographic, and intraoperative data were collected. A classification was developed using all identified causes of instability after RSA and allocating them to 1 of 3 defined treatment-guiding categories. Eight surgeons reviewed all data and applied the classification scheme to each case. Interobserver and intraobserver reliability was used to evaluate the classification scheme. Preoperative clinical outcomes were compared with final follow-up in stabilized shoulders. RESULTS: Forty-three revision cases in 34 patients met the inclusion for study. Five patients remained unstable after revision. Persistent instability most commonly occurred in persistent deltoid dysfunction and postoperative acromial fractures but also in 1 case of soft tissue impingement. Twenty-one patients remained stable at minimum 2 years of follow-up and had significant improvement of clinical outcome scores and range of motion. Reliability of the classification scheme showed substantial and almost perfect interobserver and intraobserver agreement among all the participants (κ = 0.699 and κ = 0.851, respectively). DISCUSSION: Instability after RSA can be successfully treated with revision surgery using the reliable treatment-guiding classification scheme presented herein. However, more understanding is needed for patients with greater risk of recurrent instability after revision surgery.

ABSTRACT

BACKGROUND: Pelvic ring injury classification traditionally is made using plain radiographs. Recent studies suggest that computed tomography (CT)-generated images have higher diagnostic accuracy than plain films for the classification of acetabular fractures. However, similar studies have not been performed for pelvic ring injuries. The purpose of this study was to compare CT-generated and plain radiographs in terms of the ability of surgeons at different experience levels to identify pelvic injury type. METHODS: CT-generated and plain radiograph image sets were created from 15 pelvic ring injury patients with known classification morphology. Three groups, each consisting of three orthopaedic surgeons representing different levels of expertise, viewed these image sets and recorded their diagnoses. These diagnoses were compared to the gold standard findings of the treating physician and to each other. RESULTS: Overall, there was a significantly improved ability to correctly classify pelvic ring injury type by CT-generated radiographs as compared to plain radiographs (p < 0.01). However, analysis of the groups revealed that this difference was limited to the less experienced groups (p < 0.05). CONCLUSIONS: CT-generated radiographs are diagnostically beneficial for less experienced surgeons and at least as good as conventional plain radiographs for experienced surgeons in classifying pelvic ring injuries. Therefore, CT-generated radiographs may be clinically valuable: sparing the patient additional radiation exposure and discomfort by avoiding the reordering of plain radiographs when the initial studies are of poor quality, as well as serving as a possible alternative for supplemental initial injury plain radiographic views.

ABSTRACT

INTRODUCTION: Due to the orientation of the sacroiliac joint (SIJ), as the symphysis widens in an open-book pelvic ring disruption, it should displace inferiorly. The purposes of this study were to reconfirm this inferior displacement and to evaluate the relative contributions of the pubic symphysis (PS), the sacrotuberous/sacrospinous ligament complex (STL/SSL) and the anterior sacroiliac ligament (ASIL) to pelvic ring stability in a rotationally unstable open-book injury. METHODS: For each of 6 cadaver pelves, the right hemipelvis was fixed to a table and the PS was sectioned. Under fluoroscopy, a manual external rotational force was then applied through the unfixed, left ilium. At the point of maximal displacement, a permanent AP image was obtained. With magnification corrected, horizontal (H) and vertical (V) displacements were measured. The pelves were then divided into two groups of three each. In Group 1, the PS release was followed by sectioning of the STL/SSL, and then the ASIL. In Group 2, the PS release was followed by sectioning of the ASIL and then the STL/SSL. The above described technique of manual manipulation and radiographic measurement was repeated after each stage of ligament release. RESULTS: The displacement after initial PS sectioning was not significantly different when comparing Group 1 to Group 2. In both groups, a significant and progressive increase in displacement was noted when the PS (H and V; p<0.05) and ASIL (H and V; p<0.05) were sectioned. However, there was no significant change with SSL/STL sectioning in either group. Vertical displacements were all directed inferiorly. CONCLUSIONS: The PS and ASIL are important in maintaining pelvic ring external rotational stability. However, the SSL/STL has little, if any, effect in this regard. Due to the orientation of the SIJ, external rotation of the hemipelvis, as in open-book injury, will show inferior vertical, as well as horizontal, displacement on the AP radiograph, despite the PSIL being intact.

ABSTRACT

BACKGROUND: The impact of orthopedic injuries in the elderly patient with multi-trauma and the effect of operative fixation on these injuries have not been thoroughly evaluated. METHODS: We reviewed geriatric patients (aged 65 and older) between 2004 and 2010 at a level 1 trauma center who sustained high-energy polytrauma (injury and severity score [ISS] ≥ 16) with associated orthopedic injuries. Patients were excluded if they had severe head and spine injuries, died on arrival, or had low-energy mechanisms of injury. Logistic regression was conducted to identify factors that predict mortality. RESULTS: There were 154 patients who comprised our study group with an average age of 76 years and an ISS of 23. There were 96 males and 58 females. Overall, 52 patients died within 1 year of their admission: 21 patients during their initial hospital stay and 31 patients within 1 year following admission. In all, 64 (42%) patients underwent operative stabilization of their orthopedic injuries. Increased mortality was seen (P < .05) in female patients, those with lower admission Glasgow coma score, and those who underwent orthopedic surgery. Patients had worse outcomes if they sustained femur (P = .014), clavicle, or scapular fractures (P = .027). Other factures associated with higher mortality included pelvic/acetabular injury requiring surgery (P = .019) or spine fractures treated nonoperatively (P = .014). CONCLUSION: The effect of orthopedic injuries on this geriatric polytrauma group contribute to worse outcomes when they included clavicle, scapula, and femur fractures. We also found that pelvic/acetabular fractures treated operatively and nonoperative spine fractures were associated with higher mortality rates. Risk/benefit consideration is suggested when contemplating operative intervention in these patients.

ABSTRACT

Lower extremity blast injuries represent a unique challenge to surgeons and often involve complex, limb-threatening wounds with extensive soft tissue and bone loss. Surgical treatment of these injuries can be difficult because of limited autogenous resources for reconstruction of the defect. In this article, we describe a technique for medial column reconstruction using iliac crest bone graft and soft tissue coverage with an abductor hallucis rotational flap combined with a split-thickness skin graft. This method addresses the extensive bone and soft tissue defects that frequently characterize blast injuries to the foot, and may be applicable in other situations where trauma or infection has caused extensive destruction of the medial column.
