During ACL reconstruction rehabilitation, LSI improvements indicated absolute increases in involved limb ability and were not attributable to uninvolved limb deterioration. The single-leg squat, retro step-up, single-leg hop, crossover triple hop, and timed hop are suggested as highly useful tests, since all showed initial LSI below 90%, with significant LSI improvement after rehabilitation.

"No physician can diagnose a condition he never thinks about."-Michael DeBakey P atients with acute aortic dissection (AAD) have an in-hospital mortality of 26%, and for those patients with type A AAD, the mortality risk is 1% to 2% per hour until emergency surgical repair is performed. 1,2 It is therefore critical that AAD be recognized promptly and that surgical care be provided expeditiously. Data from the International Registry of Acute Aortic Dissection (IRAD) indicate that the median time from emergency department (ED) presentation to definitive diagnosis of AAD is 4.3 hours, with an additional 4 hours between diagnosis and surgical intervention for type A patients. 2,3 A portion of the delay to surgery is often the result of the patient's presenting to smaller community hospitals underequipped to manage emergent AAD. Transfer to high-volume aortic care centers with highly specialized facilities and expertise is routine, but even at such centers, current surgical mortality is 25%. 4 Goals and Vision of the ProgramIn an effort to address factors that delay AAD recognition and optimal management, a standardized, quality-improvement protocol for the regional treatment of AAD was developed and implemented with the goal of providing consistent, integrated, and coordinated care for patients with AAD throughout all phases of care. Modeled, in part, after a successful regional program for ST-segment elevation myocardial infarction, 5 , the specific aims of the program were to decrease the time from hospital arrival to diagnosis and treatment and to improve clinical outcomes for patients with AAD. A collaborative team designed program elements directed at (1) increasing awareness and knowledge of AAD among emergency care providers, (2) standardizing optimal care for AAD through the use of a formal protocol, (3) improving care coordination and communication across disciplines, and (4) providing feedback and quality improvement to treating clinicians. This report highlights key components of the protocol, the process of implementation, and initial clinical outcomes. Methods Local Challenges in ImplementationAn interdisciplinary committee (cardiologists, cardiovascular [CV] surgeons, vascular medicine and surgeons, cardiac anesthesiologists, radiologists, AAD program nurses, community and tertiary hospital ED physicians, and a CV administrator) worked to define an ideal AAD care pathway extending from rural hospital diagnosis to tertiary care hospital discharge, and the following areas were targeted for process improvement: (1) delayed initial diagnosis, (2) nonstandardized diagnostic testing and pharmacotherapy, (3) delays occurring between community hospital presentation and interhospital transfer, (4) delays between AAD center arrival and the initiation of surgical care, (5) delays in availability and preparation of blood products for transfusion, (6) inconsistent provision of intraoperative aortic imaging; and (7) inconsistent follow-up after discharge.
Background: Current structural bone graft options used for glenoid augmentation in glenohumeral instability have known drawbacks. The scapular spine may be a possible alternative graft choice, but its dimensions and anatomy are not fully reported. Hypothesis: The scapular spine’s harvestable graft dimensions will be similar to harvestable dimensions of the coracoid and iliac crest. Study Design: Descriptive laboratory study. Methods: The scapular spine, coracoid, and iliac crest dimensions were recorded and compared bilaterally in 50 patients with 3-dimensional computed tomography imaging. The portion of the scapular spine with the largest harvestable dimensions was quantified and its location defined. Measurements were independently taken by 2 investigators and averaged for the final result. Results: The scapular spine has 81.5 mm of harvestable length and a “flare” located approximately 49.6 mm lateral to the medial scapular border, where the widest harvestable cross section is located (mean harvestable dimensions: 10.9-mm height, 11.5-mm width). Mean coracoid dimensions were 24-mm length, 14.2-mm height, and 10.6-mm width. Mean iliac crest width was 14.7 mm. In sum, 96% of scapular spines, 85% of coracoids, and 100% of iliac crests exceeded minimum dimensions of 8 mm × 8 mm × 20 mm. The coronal radius of curvature of the glenoid was significantly different from the corresponding plane of all measured structures. Conclusion/Clinical Relevance: The scapular spine has dimensions similar to the coracoid and iliac crest in the majority of patients and is therefore appropriate for further investigation as a potential graft choice in glenohumeral instability. A harvest location 49.6 mm lateral to the medial scapular border will provide the largest cross-sectional graft while avoiding the acromial base.
