The 50 most influential publications in clavicle fractures.

PURPOSE: Clavicle fractures are among the most common orthopedic fractures, and treatment methods, operative versus nonoperative, have been a point of contention. The purpose of this study was to evaluate the 50 most influential articles regarding clavicle fractures to better understand past focuses of research and to identify any gaps in knowledge. METHODS: A review of the most cited articles related to clavicle fractures was conducted using Web of Science database. A search was conducted in April 2022 by one trained researcher. Two independent researchers evaluated each article based on relevance to clavicle fracture. RESULTS: The mean number of citations was 179.1, ranging from 576 to 81 citations, and collectively cited 8954 times. The decade from 2000 to 2009 contributed the greatest portion of articles, with only a small portion coming from before 1980. The Journal of Bone and Joint Surgery-American Volume contributed the greatest number of articles (20%). The majority of the articles were therapeutic (n = 37) and focused on treatment and outcome (n = 32). Most of the clinically focused articles had a level of evidence of IV (n = 26). CONCLUSION: There is an increased influence of recent articles focused on clavicle fracture and management, due to the idea that conventional nonoperative treatment has a high rate of nonunion. Many of the most influential studies evaluate the outcomes of various treatments. Many of these studies, however, are lower levels of evidence, leaving a paucity of high level of evidence articles to support these conclusions. LEVEL OF EVIDENCE: V.

A Tale of Two Suprascapular Neuropathy Presentations: A Case ReportLearning Point of the Article.

Introduction: Supra-scapular nerve (SSN) neuropathy is a rare condition that can cause shoulder dysfunction. Prior literature has identified mass effect, space occupying lesions, trauma, and repetitive overhead activities as possible etiologies. Cases Presentations: We report two cases of SSN neuropathy; a 21-year-old competitive female volleyball player with traction associated neuropathy and a 45-year-old male with a large paralabral ganglion cyst causing compressive neuropathy. Conclusion: The following report highlights two different etiologies of SSN neuropathy and reviews the treatment of these conditions. Clinicians should consider SSN neuropathy in patients with unexplained shoulder pain and dysfunction.

Rehabilitation Protocols for Superior Capsular Reconstruction Are Variable: A Systematic Review.

PURPOSE: To screen manuscripts that discuss rehabilitation protocols for patients who underwent superior capsular reconstruction (SCR) to elucidate whether a standard rehabilitation algorithm exists for SCR. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses (i.e., PRISMA) guidelines. PubMed (MEDLINE) and Embase were searched using pertinent Boolean operation terms "superior capsular reconstruction" and "rotator cuff repair rehabilitation," and articles that included rehabilitation protocols following superior capsular reconstruction surgery were reviewed. Two independent reviewers performed the search and quality assessment. RESULTS: A total of 549 articles were yielded after our database search. Fourteen studies fulfilled our inclusion criteria and were included in the review. Study designs included 9 editorials, 3 case series, and 2 case reports. Each study included in this review used a unique rehabilitation algorithm that posed significant variability between the protocols. Four phases were identified to summarize each protocol and were used as a basis of discussion-sling versus brace time (3-6 weeks for comfort/removal vs complete immobilization), passive range of motion (immediately after surgery to initiation at 6 weeks), active range of motion (4-8 weeks), and strengthening/return to full activity (12-52 weeks). Initiation of rehabilitation, length of time spent in each phase, types of exercises, and overarching goals for return to function were significantly variable and were decided upon by the surgeon based on current massive rotator cuff repair protocols. Presently, there is no standard rehabilitation protocol for SCR. CONCLUSIONS: SCR is a relatively new procedure that is gaining rapid popularity with promising outcomes. Based on our review, there is no standard rehabilitation protocol in place; thus, it is not possible to recommend an evidence-based rehabilitation protocol following SCR at this time. LEVEL OF EVIDENCE: Level V, systematic review of Level IV and V studies.

MRI of Superior Capsular Reconstruction.

Massive irreparable rotator cuff tears can be a challenging problem for arthroscopists in the perioperative setting because the typical treatment, reverse total shoulder arthroplasty, may not be the best option for all patients. Superior capsular reconstruction (SCR) is an advancing treatment option for patients with rotator cuff tears that are neither amenable to primary repair nor ideal for arthroplasty. Patient selection, which is strongly dependent on preoperative imaging findings, is an important step in obtaining favorable surgical outcomes. The tissue quality and tear type are particularly important when considering SCR for a patient. When unsuccessful SCR is suspected, postoperative MRI of the shoulder offers the surgeon and radiologist a means of evaluating the integrity and fixation of the graft. Fluid-sensitive MRI sequences are best for examining the final SCR construct, with high-signal-intensity fluid interruptions within the graft and the presence or worsening of shoulder arthropathy indicating graft failure. The indications for SCR are discussed, and the normal postoperative MRI findings after SCR are described in this review. In addition, the common types of SCR graft failure and associated imaging findings are described and illustrated. ©RSNA, 2020.

Subscapularis tenotomy versus lesser tuberosity osteotomy during total shoulder arthroplasty for primary osteoarthritis: a prospective, randomized controlled trial.

BACKGROUND: There is no current consensus on subscapularis mobilization during total shoulder arthroplasty. The purpose of this prospective, randomized controlled trial was to compare functional and radiographic outcomes of the more traditional subscapularis tenotomy (ST) versus lesser tuberosity osteotomy (LTO). METHODS: This study enrolled 60 shoulders in 59 patients with primary osteoarthritis. Thirty shoulders were preoperatively randomized to each group. Preoperative and 6-week, 3-month, 6-month, and 1-year postoperative data were collected. Ultrasound was performed at 3 months to evaluate subscapularis healing in tenotomy subjects, whereas radiographs were used to evaluate osteotomy healing. Intraoperative data included operative time, tenotomy or osteotomy repair time, and osteotomy thickness. RESULTS: No significant differences in range of motion or clinical outcomes occurred at baseline or 1 year postoperatively between the 2 groups. The mean total case duration for ST was significantly less than that for LTO (129.3 minutes vs 152.7 minutes), along with a significantly shorter subscapularis repair time for ST (34.3 minutes vs 39.3 minutes, P = .024). At final follow-up, 27 of 29 LTO shoulders (93.1%) showed bone-to-bone healing on radiographs, whereas 26 of 30 ST shoulders (86.7%) had no full-thickness tear of the subscapularis on ultrasound at 3 months. CONCLUSIONS: Both techniques produced successful objective and subjective clinical outcomes. LTO heals more reliably than ST. Mean total case and subscapularis repair times were significantly greater for LTO than for ST.

Short-term outcomes associated with drain use in shoulder arthroplasties: a prospective, randomized controlled trial.

BACKGROUND: This study examined the immediate outcomes during the perioperative period associated with drains in the setting of total shoulder arthroplasty or reverse shoulder arthroplasty. We hypothesized that drain use would result in lower postoperative hemoglobin and hematocrit levels that would increase transfusion rates and longer hospital stays that would increase hospital costs. METHODS: The study prospectively randomized 100 patients (55% women; average age, 69.3 years) who underwent total shoulder arthroplasty or reverse shoulder arthroplasty to receive a closed-suction drainage device (drain group, n = 50) or not (control group, n = 50) at the time of wound closure. Basic demographic information and intraoperative and postoperative data were collected. RESULTS: The groups were similar with respect to basic patient demographics. Postoperatively, drains had no effect on transfusion rates or any perioperative complication (P > .715). There were also no significant differences in hemoglobin or hematocrit levels immediately after surgery or on postoperative day 1. On average, patients were discharged from the hospital 1.6 days and 2.1 days postoperatively in the control and drain groups, respectively (P = .124). The average cost associated for the control cohort's hospital stay was $35,796 ± $13,078 compared with $43,219 ± $24,679 for the drain cohort (P = .063). DISCUSSION: Drain use after shoulder arthroplasty had no appreciable difference on short-term perioperative outcomes, postoperative anemia, length of hospital stay, or cost. It is possible that the potential negative effects of postoperative drainage are blunted by the routine use of tranexamic acid.

A higher altitude is an independent risk factor for venous thromboembolisms following total shoulder arthroplasty.

INTRODUCTION: High altitudes lead to physiological changes that may predispose to venous thromboembolisms (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE). No prior study has evaluated if there is also a higher risk of VTEs after total shoulder arthroplasties (TSAs) performed at higher elevations compared to lower elevations. The purpose of this study was to identify if undergoing TSA at a higher altitude center (>4000 feet above sea level) is an independent risk factor for a postoperative VTE. METHODS: A retrospective review was performed from 2005 to 2014 using the Medicare Standard Analytical Files of the Pearl Diver database (Pearl Diver Technologies, West Conshohocken, PA, USA). The inclusion criteria for the study group consisted of all patients in the database undergoing primary TSAs at an altitude above 4000 feet. Patients were queried using the International Classification of Disease 9th revision codes (ICD-9). All patients undergoing primary TSA were queried using ICD-9 procedure code 81.80. Patients were filtered using the zip codes of the hospitals where the procedure occurred and were separated into high (>4,000 ft) and low (<100 ft) altitudes. Patients undergoing TSA in altitudes <100 ft represented the control group. Patients with a history of VTE, DVT, PE, and coagulation disorders were excluded from the study. Patients in the study group were randomly matched 1:1 according to age, gender, and comorbidities. Two mutually exclusive cohorts were formed and rates of VTE, DVT, and PE were analyzed and compared. Statistical analysis was performed using the programming language R (University of Auckland, New Zealand). An alpha value less than 0.05 was considered statistically significant. RESULTS: In the first 30 postoperative days, patients undergoing TSA at a higher altitude experienced a significantly higher rate of PEs (odds ratio [OR], 39.5; P = <0.001) when compared to similar patients at lower altitudes. This trend was also present for PE (OR, 2.02; P < 0.03) at 90 days postoperatively. CONCLUSION: TSAs performed at higher altitudes (>4000 feet) have a higher rate of acute postoperative PEs in the first 30 days and 90 days postoperatively when compared to matched patients receiving the same surgery at a lower altitude (<100 feet). TSA patients at high altitude should be counseled on these increased risks.
