Background: Instrumented lumbar fusion can be accomplished through open or minimally invasive techniques. The focus of this study was to compare perioperative narcotic usage and length of hospital stay between patients undergoing open versus minimally invasive spinal surgery (MISS). Methods: A retrospective chart review was performed on 110 patients who underwent instrumented lumbar fusion over 2 years at our institution. These patients were divided into two groups: those that received open transforaminal interbody fusion (n=69), and those whose surgeries were performed minimally invasively with lateral lumbar transpsoas interbody fusion (LLIF) and percutaneous pedicle screws (n=41). Narcotic usage was recorded for both groups intra-operatively and post-operatively throughout their hospital stay. These values were standardized using an equianalgesia chart. Results: Average narcotic usage post-operatively was significantly lower for the LLIF group relative to those who underwent open lumbar fusion (278.48 vs. 442.06 mg, P=0.03). The average length of postoperative hospital stay was significantly shorter for patients who underwent LLIF compared to those who had an open procedure (4.10 vs. 6.19 days, P=0.02). Conclusions: Patients who underwent minimally invasive surgery (MIS) LLIF had decreased overall use of opioids in the perioperative period and shorter hospital stays when compared to patients who underwent the open transforaminal interbody fusion approach. These findings support pre-existing literature in favor of LLIF MISS with regards to the above stated outcome measures. The long-term benefits of MISS with regards to narcotic usage in spine patients are not yet known.
The functional success of anatomic total shoulder arthroplasty (TSA) relies heavily on the healing integrity of the subscapularis tendon. Access to the glenohumeral joint is performed through a deltopectoral approach, and takedown of the subscapularis tendon is necessary in most surgeons' hands. Although initially described as a tenotomy, lesser tuberosity osteotomy and subscapularis peel are two techniques more commonly used today. Both of these options offer good results as long as proper repair is done. A subscapularis-sparing approach has more recently been advocated but is technically demanding. Failure of tendon repair can lead to early failure of anatomic total shoulder arthroplasty with accelerated glenoid loosening, decreased function, and anterior instability. Treatment options for subscapularis insufficiency include nonsurgical management, revision tendon repair, tendon reconstruction or transfer, or conversion to reverse shoulder arthroplasty. As shoulder arthroplasty continues to become increasingly prevalent, subscapularis insufficiency, too, will become more common. Accordingly, a surgeon's knowledge of subscapularis management in an arthroplasty setting must encompass treatment options for postoperative subscapularis insufficiency. P roper assessment, handling, and repair of the rotator cuff tendons are vital to a successful clinical outcome after total shoulder arthroplasty (TSA). Although tendon-sparing surgical approaches have been proposed, most TSA surgeries conducted still use a subscapularis tendon takedown to gain access to the glenohumeral joint. Failure to adequately repair the subscapularis tendon or rupture of the tendon postoperatively can lead to poor outcomes including pain, loss of motion, instability, and even accelerated implant loosening (Figure 1). In cases of failure where repair is not an option, various tendon transfers or augmentation procedures can be considered. In some cases, conversion to a reverse shoulder arthroplasty (RSA) may be necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
