Postoperative Rehabilitation and Return to Play Criteria After Anterior Shoulder Stabilization Procedures

Anterior shoulder stabilization surgery is the preferred method to treat shoulder instability in athletes; however, a variety of surgical techniques exist. The rehabilitation specialist needs to have a basic understanding of each procedure to properly protect healing structures while restoring range of motion, strength, and functional abilities. Few evidence-based guidelines exist for rehabilitation after anterior shoulder stabilization, and those that are available are specific to the standard arthroscopic approach. Further, even less guidance is available for the later stages of rehabilitation and return to sports preparation and decision making. In this review article, rehabilitation considerations and alterations for variations of anterior shoulder stabilization surgery are presented. The importance of individualizing late-stage rehabilitation and incorporating core and lower extremity exercises as appropriate is also discussed. Lastly, rationale for criteria-based return to sports assessments to aid clinical decision making is presented.

Assessing and Characterizing Bone Loss in Anterior Shoulder Instability

Glenoid bone loss and Hill-Sachs lesions have independently been recognized as strong predictors of recurrent instability, failure of soft tissue shoulder stabilization procedures, ultimately resulting in patient dysfunction and morbidity. Significant focus has been directed toward recognition, measurement, and classification of bone loss in anterior shoulder instability through concepts such as the glenoid track and evolving treatment algorithms. Preoperative recognition of glenohumeral bone loss through history, physical examination, and a comprehensive imaging workup and interpretation is critical to formulating a treatment plan and permits informed consent and shared decision making with the patient in these complex cases. We provide a comprehensive review of the pathophysiology and presenting symptoms of glenoid bone loss and humeral head lesions, detail the various bone loss estimation methods used in preoperative planning, and outline the comprehensive assessment of combined lesions based on current evidence-based algorithms.

Increased Risk of Short-Term Complications and Venous Thromboembolism in Latarjet-Bristow Procedures Compared With Bankart Repairs

PurposeTo (1) determine the rate of surgical complications and venous thromboembolism (VTE) in patients undergoing arthroscopic Bankart repair, open Bankart repair, or Latarjet-Bristow; and (2) assess potential risk factors for surgical complications and VTE in patients undergoing shoulder stabilization procedures. MethodsThe NSQIP database was used to identify patients undergoing isolated surgery for shoulder instability from 2005 to 2017. Demographic data were collected and compared. Logistic regression was used to assess the risk factors for developing a postoperative complication, and regression analyses were used to evaluate the odds of postoperative complications between types of surgery. ResultsWe identified 7,233 patients for inclusion. Patients undergoing Latarjet-Bristow were more likely to be male and Black and to report current tobacco use. Overall, there was a low rate of surgical complications (0.4%) and VTE (0.2%). However, patients undergoing Latarjet-Bristow had nearly a 10-fold increase in the risk of surgical complications compared with an arthroscopic or open Bankart repair (1.9% versus 0.2%, P < .001), including deep surgical site infections, return to operating room within 30 days, and symptomatic VTE (deep venous thrombosis rate: arthroscopic Bankart repair, 0.1%; Latarjet-Bristow, 0.8%; P < .001). There were no differences in the odds of developing a surgical complication or VTE between patients undergoing arthroscopic or open Bankart repair. ConclusionThis study used a nationally representative, widely validated, peer-reviewed database to demonstrate that patients undergoing a Latarjet-Bristow procedure are at significantly higher risk for short-term postoperative complications, including deep surgical site infections, return to the operating room, and symptomatic VTE, than those undergoing Bankart repair. These findings should not discourage surgeons from proceeding with a coracoid transfer procedure when indicated for glenoid deficiencies, but should inform preoperative counseling and help guide perioperative care to optimize patient outcomes.

Outcome of biceps suspensionplasty for recurrent multidirectional shoulder instability

IntroductionRecurrent multidirectional shoulder instability after failed capsular repair/plication, is a challenging treatment problem. The long head of the biceps has been identified as a structure that may be utilized as a checkrein to stop abnormal anterior and inferior translation of the humeral head. The purpose of this study is to analyse the outcomes of biceps suspensionplasty (BS) in the treatment of recurrent shoulder instability. MethodsA retrospective review identified patients with recurrent multidirectional instability that underwent BS as part of a revision shoulder stabilization procedure. Clinical records were reviewed for demographics, pain, complications, recurrent instability, reoperations, and range of motion. Patients were also administered ASES/SST/SANE/Rowe and Oxford instability questionnaire at minimum of 2-year clinical follow-up. ResultsFive patients (7 shoulders) were included with a mean follow-up of 3.2 years (2–7 years). Patients had an average of 1.6 prior procedures (1–3). Average patient age was 24.2 years (18.7–32.4 years) and all were female. Four shoulders were treated open while 3 were treated arthroscopically with a capsular shift and biceps suspension. Four shoulders also underwent capsular reconstruction with allograft. At final follow-up three shoulders had recurrent inferior subluxation, although all patients considered their shoulders to be much better (4) or somewhat better (3) and none have undergone repeat surgery. ConclusionIn our series of patients, we found BS may be useful as an adjunct to a revision capsular shift or reconstruction. While 42.8% of patients experienced recurrent subluxations, this high-risk population demonstrated encouraging subjective results and avoiding joint arthrodesis in the short-term.

The financial burden associated with multiple shoulder dislocations and the potential cost savings of surgical stabilization

IntroductionShoulder dislocation is a costly problem and can have a high risk for recurrent instability after initial dislocation based on well-defined patient characteristics. Patients with recurrent instability can be treated with shoulder stabilizing procedures. Although more costly, surgery may decrease the overall health care burden of managing a patient with multiple shoulder dislocations nonoperatively.MethodsWe performed a retrospective chart review of all patients who presented to the emergency department (ED) with a diagnosis of a shoulder dislocation at a level 1 academic trauma center during the year 2016. Patient information regarding the current dislocation episode, previous dislocations, shoulder surgeries, and postreduction follow-up was gathered. These data were then used to determine the average cost of an ED presentation for a shoulder dislocation episode as obtained from the hospital finance department. The average cost of shoulder stabilization surgery was used to conduct a cost-benefit analysis of operative vs. nonoperative management.ResultsData were collected on 104 individuals who presented to the ED with shoulder dislocations. Of these, 65 were primary dislocations and 39 were recurrent dislocations. Twelve patients underwent shoulder stabilization surgery after their ED presentation. The average cost to the institution for an ED visit requiring the closed reduction of a shoulder dislocation was $2207 ($973.21 without sedation and $3744 with conscious sedation). The average cost of a shoulder stabilization procedure performed at this same institution was $7807.Discussion and conclusionAlthough shoulder stabilization has a higher cost on the front end, this intervention results in cost savings if it prevents 2-3 future shoulder dislocations resulting in ED visits. These findings suggest that, for patients with a high risk for recurrent instability, not only would stabilization surgery help prevent subsequent dislocation events but would also minimize health care costs.

Shoulder arthroplasty to address the sequelae of anterior instability arthropathy and stabilization procedures: systematic review and meta-analysis.

Chronic anterior glenohumeral joint instability is a common situation and can lead to progressive cartilage deterioration and ultimately instability arthopathy. Progressive cartilage deterioration can occur despite conservative or surgical treatment and the sequelae of these conditions are often addressed with total shoulder arthroplasty. Aims of the present study were to analyze the available literature to describe the technical aspects of this particular operation and to report outcomes and complication rates. The hypothesis was that shoulder arthropalsty in the sequelae of instability had lower outcomes and higher complication rates than arthroplasties for primary arthritis. A systematic review of the literature was performed, in accordance with the PRISMA guidelines. PubMed, Ovid, Cochrane Reviews, and Google Scholar were comprehensively searched using a combination of the following keywords: shoulder arthroplasty, reverse shoulder arthroplasty, dislocation arthropathy, capsulorrhaphy arthropathy and stabilization procedures. Thirteen studies with 365 patients met inclusion criteria. Since 13 patients were lost to follow-up, 352 were reviewed at an average follow-up of 53.4months. The average Constant-Murley (CM) and American Shoulder and Elbow Society (ASES) scores improved from 35.6 and 35.7 to 72.7 and 77, respectively. The overall complication rate was 25.7% and the reoperation rate was 18.5%. Radiographs at follow-up revealed radiolucent lines on the humerus in 12.4% of cases and radiolucent lines or notching on the glenoid side in 22.7% of cases. The average Methodological Index for Non-randomized Studies Score (MINORS) was 12.9 for non-comparative studies and 21.3 for comparative studies. Shoulder arthroplasty to address the sequelae of instability arthropathy and stabilization procedures can be a challenging procedure as a consequence of the distorted anatomy and severe glenohumeral joint pathology. Complication and reoperation rates are higher compared to shoulder arthroplasty for primary glenohumeral joint arthritis; however, the difference is not statistically significant. When reverse shoulder arthroplasties (RSA) were considered as a subgroup and compared to anatomic shoulder replacements (total shoulders and hemiarthroplasties), they showed a lower revision rate.

Surgical stabilization of pediatric anterior shoulder instability yields high recurrence rates: a systematic review

The purpose of this systematic review was to assess the surgical techniques, indications outcomes and complications for pediatric patients (≤ 19years old) undergoing shoulder stabilization procedures for anterior shoulder instability. The electronic databases MEDLINE, EMBASE, CINAHL, and Web of Science were searched from data inception to March 14, 2019 for articles addressing surgery for pediatric patients with anterior shoulder instability. The Methodological Index for Non-randomized Studies (MINORS) tool was used to assess the quality of included studies. Overall 24 studies, with a total of 688 patients (696 shoulders) and a mean age of 16.6 ± 2.5years met inclusion criteria. Mean follow-up was 49 ± 26months. The majority (59%) of studies only offered shoulder stabilization procedures to patients with more than one shoulder dislocation, however, three studies reported operating on pediatric patients after first time dislocations. Of the included patients 525 had arthroscopic Bankart repair (78%), 75 had open Bankart repair (11%), 34 had modified Bristow (5%), and 26 had Latarjet (4%) procedures. The overall complication rate was 26%. Patients undergoing arthroscopic Bankart repair experienced the highest recurrence rate of 24%. There were no significant differences in recurrent instability (n.s.) or loss of external rotation (n.s.) in pediatric patients treated with arthroscopic Bankart repair compared to open Latarjet. Patients had a 95% rate of return to sport at any level (i.e. preinjury level or any level of play) postoperatively (95%). Pediatric patients are at high risk of recurrent instability after surgical stabilization. The majority of pediatric patients with anterior shoulder instability were treated with arthroscopic Bankart repair. Most studies recommend surgical stabilization only after more than one dislocation. However, given the high rates of recurrence with non-operative management, it may be reasonable to perform surgery at a first-time dislocation, particularly in those with other risk factors for recurrence. With the current evidence and limited sample sizes, it is difficult to directly compare the surgical interventions and their post-operative efficacy (i.e. re-dislocation rates or range of motion). There was an overall high rate of return to sport after surgical stabilization at final follow-up. IV.

Failed shoulder stabilization procedure in the elderly: reverse shoulder replacement is the treatment ultimum

&lt;p class="abstract"&gt;Shoulder instability, though often seen in younger individuals it can also occur in the elderly. Shoulder instability in the elderly is often missed and definitive management gets delayed. Treatment delay has a significant influence on the choice of surgical procedure and its functional outcome. We report a 77 year old female who presented with a missed anterior dislocation of the glenohumeral joint. She had undergone an open Latarjet procedure for shoulder instability eight months before her presentation. Considering her age, humeral head bone defects, rotator cuff tear and degenerative changes in the joint we opted for a Reverse Shoulder Replacement in her. The patient now has a pain free, stable and mobile shoulder joint. Her pre-operative Constant score was 11 which improved to 67 at 6 months follow up. Now after 12 months follow up, she has active flexion up to 150°, abduction- 90°, external rotation- 10°, internal rotation- 30&lt;sup&gt;0&lt;/sup&gt; and extension- 50°. Reverse shoulder replacement is a viable treatment option for chronic locked shoulder dislocations with concomitant rotator cuff lesions. Though there is a concern about failure of the glenoid component due to bone defects, RSA is still preferable in elderly patients with low functional demand.&lt;/p&gt;

Opioid use following shoulder stabilization surgery: risk factors for prolonged use

The purpose of this study was to determine the rate of opioid use before and after shoulder stabilization surgery for instability due to recurrent dislocation and assess patient factors associated with prolonged opioid use postoperatively. Patients undergoing primary shoulder stabilization procedures for shoulder instability due to recurrent dislocation were accessed from the Humana administrative claims database. Patients were categorized as those who filled 1 or more opioid prescriptions within 1 month, those who filled opioid prescriptions between 1 and 3 months, and those who never filled opioid prescriptions before surgery. Rates of opioid use were evaluated preoperatively and longitudinally tracked for each group. Multiple binomial logistic regression analysis was used to identify factors associated with opioid use at 3 months and 1 year after surgery. Overall, 4802 patients (45.9% opioid naive) underwent shoulder stabilization surgery for shoulder instability during the study period. Rates of opioid use significantly declined after the first postoperative month; however, at 1 year, the rate of opioid use was significantly greater in patients who filled opioid prescriptions preoperatively (13.4% vs. 1.9%, P < .0001). Filling opioid prescriptions 1 to 3 months prior to surgery was the strongest risk factor for opioid use at 1 year after surgery. Patients who were prescribed opioids 1 to 3 months before surgery had the highest risk of prolonged opioid use following surgery. Obesity, tobacco use, and a preoperative diagnosis of fibromyalgia were independently associated with prolonged opioid use following surgery.

Rotator interval closure: inconsistent techniques and its association with anterior instability. A literature review.

The Rotator interval (RI) is an anatomic space in the anterosuperior part of the glenohumeral joint. An incompetent or lax RI has been implicated in various conditions of shoulder instability and therefore RI has been frequently touted as an area that is important in preserving stability of the shoulder. Biomechanical studies have shown that repair of RI ligamentous and capsular structures decreases glenohumeral joint laxity in various directions. Clinical studies have reported successful outcomes after repair or plication of these structures in patients undergoing shoulder stabilization procedures. Although varieties of methods have been described for its closure, the optimal surgical technique is unclear with various inconsistencies in incorporation of the closure tissue. This in particular makes the analysis of the RI closure very difficult. The purposes of this study are to review the structures of the RI and their contribution to shoulder instability, to discuss the biomechanical and clinical effects of plication of RI structures in particular to anterior glenohumeral instability, to delineate the differences between an arthroscopic and open RI closure. Additionally, we have proposed a new classification system describing various techniques used during RI closure.

Analysis of complication after open coracoid transfer as a revision surgery for failed soft tissue stabilization in recurrent anterior shoulder instability

The coracoid transfer represents a treatment option for patients with recurrent shoulder instability. Only a few studies exist about the complication rate of the coracoid transfer as a revision surgery following failed soft tissue stabilization. The purpose of this study was to analyze the results and complication rate after coracoid transfer as a revision surgery. In this study 38 patients (4 females, 34 males, mean age 27years) were included of whom 29 patients were available for follow-up after a mean of 27months. Previous shoulder stabilization procedures were predominantly arthroscopic (n = 25). Complications were divided according to their timely appearance into early (< 3months) and late (> 3months) postoperatively as well as need for revision. Clinical scores [Constant Score (CS), Rowe Score (RS), Walch-Duplay-Score (WDS), WOSI and Subjective-Shoulder-Value (SSV)] were evaluated preoperatively and at final follow-up. In this patient cohort, the overall complication rate was 27.6%, all of them occurred > 3months postoperatively. In seven of eight cases (24.1%) a repeat surgical procedure was conducted. Recurrent instability occurred in three patients (10.3%) of which two received a revision surgery (n = 1 iliac-crest bone graft, n = 1 labral repair). Due to persistent pain five patients underwent an arthroscopic implant removal. The complication rate was with 40% higher in patients with two or more previous surgeries (n = 4 out of 10 patients) compared to patients with one previous surgery (21%, n = 4 out of 19 patients). The scores increased significantly comparing pre- to postoperative [CS 74-90 points, RS 27-91 points, WDS 16-89 points, WOSI 40-76% and SSV 41-82% (p < 0.05)]. The open coracoid transfer as a revision surgery after failed soft tissue stabilization leads to satisfying clinical results. However, the complication rate is high though comparable to data in the literature when used as a primary surgery. The indication for a coracoid transfer should be judged carefully and possible alternatives should be considered.

Patients Undergoing Shoulder Stabilization Procedures Do Not Accurately Recall Their Preoperative Symptoms at Short- to Midterm Follow-up.

Background:A patient’s ability to recall symptoms is poor in some elderly populations, but we considered that the recall of younger patients may be more accurate. The accuracy of recall in younger patients after surgery has not been reported to date.Purpose:To assess younger patients’ abilities to recall their preoperative symptoms after having undergone shoulder stabilization surgery. We used 2 disease-specific, patient-reported outcome measures (PROMs)—the Western Ontario Shoulder Instability Index (WOSI) and the Melbourne Instability Shoulder Score (MISS)—at a period of up to 2 years postoperatively.Study Design:Cohort study (diagnosis); Level of evidence, 2.Methods:Participants (N = 119) were stratified into 2 groups: early recall (at 6-8 months postoperatively; n = 58) and late recall (at 9-24 months postoperatively; n = 61). All patients completed the PROMs with instructions to recall preoperative function. The mean and absolute differences between the preoperative scores and recalled scores for each PROM were compared using paired t tests. Correlations between the actual and recalled scores of the subsections for each PROM were calculated using an intraclass correlation coefficient (ICC). The number of individuals who recalled within the minimal detectable change (MDC) of each PROM was calculated.Results:Comparison between the means of the actual and recalled preoperative scores for both groups did not demonstrate significant differences (early recall differences, MISS 1.05 and WOSI –38.64; late recall differences, MISS –0.25 and WOSI –24.02). Evaluation of the absolute difference, however, revealed a significant difference between actual and recalled scores for both the late and early groups (early recall absolute differences, MISS 12.26 and WOSI 216.71; late recall absolute differences, MISS 12.84 and WOSI 290.08). Average absolute differences were above the MDC scores of both PROMs at both time points. Subsections of each PROM demonstrated weak to moderate correlations between actual and recalled scores (ICC range, 0.17-0.61). Total scores for the PROMs reached moderate agreement between actual and recalled scores.Conclusion:Individual recall after shoulder instability surgery was not accurate. However, the mean recalled PROM scores of each group were not significantly different from the actual scores collected preoperatively, and recall did not deteriorate significantly over 2 years. This suggests that recall of the individual, even in this younger group, cannot be considered accurate for research purposes.

Coracohumeral Ligament Reconstruction for Patients With Multidirectional Shoulder Instability

Coracohumeral ligament pathology arises from acute trauma, capsular thickening, or congenital connective tissue disorders within the glenohumeral joint. Recent studies have highlighted the significance of this pathology in multidirectional shoulder instability because insufficiency of the rotator interval has become increasingly recognized and attributed to failed shoulder stabilization procedures. The diagnosis and subsequent treatment of coracohumeral ligament pathology can be challenging, however, because patients usually present with a history of failed surgical stabilization and persistent laxity. At the time of presentation, most patients have undergone failed nonoperative treatments and are indicated for surgical intervention. One of the options for the treatment of coracohumeral ligament pathology is reconstruction. The purpose of this Technical Note is to describe our preferred surgical technique for the reconstruction of the coracohumeral ligament. Research was performed at the Steadman Philippon Research Institute.

Shoulder Arthrodesis in the Management of Glenohumeral Pathologies

BackgroundIn an era of advanced shoulder stabilization procedures, arthroplasty implants and techniques, shoulder arthrodesis is considered an end-stage salvage procedure with negative connotations. However, in correctly selected patients, arthrodesis can alleviate pain, provide acceptable and stable motion, with a resultant functional shoulder.MethodsThe current literature on shoulder arthrodesis was reviewed to determine the indications, surgical technique, post-operative rehabilitation, complications and outcomes.ResultsIndications for shoulder arthrodesis include brachial plexus injuries, paralytic disorders, pseudo paralysis from combined severe/irreparable rotator cuff and deltoid injuries, inflammatory arthritis with severe rotator cuff pathology, persistent refractory instability, and tumor resection. Shoulder arthrodesis generally involves compression screws with or without plate fixation and bone graft. The arthrodesis is positioned to optimize the function of the extremity, primarily for activities of daily living. Postoperatively, most patients are immobilized for 8 to 10 weeks, dependent on the completeness of radiological fusion. Complications include nonunion, shoulder girdle muscle atrophy, painful hardware, periprosthetic fractures, and infection.DiscussionWith the use of recent biological innovations, the nonunion rate has declined, and rehabilitation technologies have allowed maintenance of muscle mass for future conversion to shoulder arthroplasty. Hence, in carefully selected patients, shoulder arthrodesis provides a valuable option for a stable, functional, and pain-free shoulder and should be retained as part of the treatment algorithm for complex shoulder pathology.

Return to Sport After Surgical Treatment for Anterior Shoulder Instability: A Systematic Review

Background: For athletes, a return to preinjury activity levels with minimal time away is a metric indicative of successful recovery. The knowledge of this metric would be helpful for the sports medicine specialist to advise patients on appropriate expectations after surgery. Purpose: To evaluate the rate and amount of time needed for athletes to return to sport (RTS) after different surgical treatments for anterior shoulder instability. Study Design: Systematic review and meta-analysis. Methods: The MEDLINE, EMBASE, and Cochrane databases were searched for articles relevant to athletes’ RTS after surgical anterior shoulder stabilization with variants of the Latarjet and Bankart procedures. Article selection was based on relevant inclusion and exclusion criteria. After the articles were reviewed, the data pertinent to rates of and time to RTS were extracted, compiled, and analyzed. Results: Sixteen articles met the inclusion criteria. Based on these articles, the rate of RTS was 97.5% after arthroscopic Bankart, 86.1% after open Bankart, 83.6% after open Latarjet, 94.0% after arthroscopic Latarjet, and 95.5% after arthroscopic Bankart with remplissage. Among the athletes who did RTS, arthroscopic Bankart had the highest rate of return to preinjury levels (91.5%), while arthroscopic Latarjet had the lowest rate (69.0%). The time to RTS was 5.9 months after arthroscopic Bankart, 8.2 months after open Bankart, 5.07 months after open Latarjet, 5.86 months after arthroscopic Latarjet, and 7 months after arthroscopic Bankart with remplissage. Conclusion: Of the pooled data, patients who underwent arthroscopic Bankart showed the highest rate of RTS, while patients who underwent open Latarjet showed the shortest time to RTS. Return to preinjury level was highest in the arthroscopic Bankart group and lowest in the arthroscopic Latarjet group. Physicians can utilize these data to set expectations for their patient-athletes regarding RTS after anterior shoulder stabilization procedures. Clinical Relevance: When treating an athlete, many factors must be taken into account to weigh treatment options. Two important factors to consider with the patient-athlete are the rate of return to the previous activity level and the timeline for this to occur. This study provides a guide for physicians and a time frame for athletes with respect to the mean percentage and time for return to sport after different surgical procedures for anterior shoulder instability.

Early return to baseline range of motion and strength after anterior shoulder instability surgery: a Multicenter Orthopaedic Outcomes Network (MOON) shoulder group cohort study

Patients often return to higher-level activities and sports at 4 to 8 months after anterior shoulder stabilization procedures. It is unknown what percentage of patients have regained normal function at this time frame and what factors predict residual deficits, range of motion (ROM), and strength after anterior shoulder instability surgery. Ten participating sites throughout the United States enrolled patients in a prospective cohort study including primary, revision, arthroscopic, and open anterior stabilization procedures. Baseline demographic data and patient outcomes questionnaires were collected with initial physical examination, treatment, surgical findings, and surgical repair details. At the 6-month follow-up visit, ROM and strength measurements were collected and compared with preoperative measurements. There were 348 patients identified who underwent surgical treatment for anterior shoulder instability. Of these, 259 patients (74.0%) returned to baseline, and 89 (26.0%) did not return to baseline shoulder ROM (≥20° loss of ROM) or strength. A higher Beighton score (P = .01) and number of dislocations (P < .01) were associated with failure to regain baseline ROM and strength at early follow-up. No surgical variables were found to influence return to baseline function, including open vs. arthroscopic surgery, primary vs. revision surgery, and number of suture anchors. By 4 to 8 months postoperatively, 76% of patients return to baseline ROM, 98% return to baseline strength, and 74% return to both baseline ROM and strength. An increased number of dislocations and generalized joint laxity were associated with failure to return to baseline ROM and strength at early follow-up after anterior shoulder instability surgery.

Incidence and Changing Trends of Shoulder Stabilization in the United States

To determine the incidence and demographic characteristics of shoulder stabilization in the United States, with particular focus on age, sex, and inpatient versus outpatient treatment. The National Hospital Discharge Survey and the National Survey of Ambulatory Surgery databases were searched using a combination of International Classification of Diseases, Ninth Revision diagnosis and procedure codes, encompassing open and arthroscopic shoulder stabilization procedures. Incidence was determined using National Survey of Ambulatory Surgery, National Hospital Discharge Survey, and US census data, and the results were stratified by age, sex, facility, and concomitant diagnoses. Data were analyzed between 1994 and 2006, the most recent year for which data are available within these sources. The incidence of shoulder stabilization in the United States was 5.84 per 100,000 person-years (n= 15,514; 95% confidence interval, 11,975-19,053) in 1994 to 1996 and 6.89 per 100,000 person-years (n= 20,588; 95% confidence interval, 16,254-24,922) in 2006 (P= .0697). The number of inpatient procedures decreased significantly whereas the number of outpatient procedures increased significantly over the same period (P < .0001 for both). The incidence of stabilization increased in patients aged 45 to 64years (P < .0001) and patients aged 65years or older (P= .0008) but was unchanged in patients aged 44years or younger (P= .4745). The average age of patients undergoing stabilization increased over the study period, from 30years to 47years for inpatients (P= .01) and from 27years to 34years for ambulatory patients (P= .05). The incidence of stabilization increased significantly in male patients (P= .0075) but remained stable in female patients (P= .8057) over the same period. Diagnoses related to rotator cuff pathology and shoulder derangement were the most common concurrent diagnosis codes. The overall incidence of shoulder stabilization in the United States is 6.89 per 100,000 person-years. The incidence increased by 18% between 1994 and 2006. During the study period, shoulder stabilization shifted to become a largely outpatient procedure, and the average age increased significantly. Level IV, therapeutic case series.

Trends in Shoulder Stabilization Techniques Used in the United States Based on a Large Private-Payer Database.

Background:Arthroscopic stabilization is the most broadly used surgical procedure in the United States for management of recurrent shoulder instability. Latarjet coracoid transfer has been considered a salvage surgical procedure for failed arthroscopic repairs or cases of significant glenoid bone loss; however, with recent literature suggesting reduced risk of recurrent instability with Latarjet, several surgeons have advocated its broader utilization as a primary operation for treatment of shoulder instability.Purpose:To determine trends in shoulder stabilization techniques used in the United States.Study Design:Cross-sectional study.Methods:A retrospective analysis of a publicly available national insurance database was performed to identify shoulder stabilization procedures performed over 9 years (2007-2015). The following Current Procedural Terminology codes were searched: 29806 (arthroscopic stabilization), 23455 (open capsulolabral repair), 23466 (open capsular shift), 23462 (Latarjet coracoid transfer), and 23460 (open anterior capsulorrhaphy with other bone block augmentation). Outcomes of interest included (1) trends in the use of each technique throughout the study interval, (2) age and sex distributions of patients undergoing each technique, and (3) regional predilections for the use of each technique.Results:Arthroscopic stabilization was the most broadly used shoulder stabilization procedure in the database (87%), followed by open Bankart (7%), Latarjet (3.2%), open capsular shift (2.6%), and alternative bone block procedure (0.8%). Throughout the study period, the incidence of arthroscopic stabilization and Latarjet increased (8% and 15% per year, respectively); the incidence of open capsular shift remained relatively constant; and the incidence of open Bankart decreased (9% per year). Arthroscopic stabilization, open Bankart, and Latarjet each had similar sex-based distributions (roughly 70% male), while open capsular shift and alternative bone block were relatively more common in females (54% and 50% male, respectively). The incidence of arthroscopic stabilization and Latarjet were greatest in the South and lowest in the Northeast.Conclusion:Arthroscopic stabilization remains the most commonly utilized stabilization technique in the United States. The use of the Latarjet procedure is steadily increasing and now rivals open Bankart stabilization among the most commonly used open stabilization techniques.

Complications Following Anterior Shoulder Instability Treatment: Bankart Repair Versus Latarjet

The rate of utilization of Latarjet and arthroscopic Bankart repair has increased in the US in the past seven years, with the odds of requiring a reoperation or developing any post-operative complication were greater following Latarjet versus Bankart repair. Utilization of the Latarjet procedure for recurrent anterior shoulder instability has increased in recent years; however, reported complication rates following Latarjet are based upon small, non-comparative studies. The purpose of this study was to utilize a large population cohort to compare complication and reoperation rates following the Latarjet procedure to those following the current gold standard, arthroscopic Bankart repair. Using current procedural terminology (CPT) codes, a population database was used to generate a cohort of patients who underwent the Latarjet procedure and Bankart repair between 2007 and 2014 in the United States (US). Complications following either procedure were identified using International Classification of Diseases (ICD)-9 codes, including deep vein thrombosis/pulmonary embolus (DVT/PE), nerve injury, surgical site infection (SSI), hematoma, capsulitis, and dislocation, while CPT codes were used to determine overall and procedure specific reoperations, including irrigation and debridement (I&D), open reduction, and lysis of adhesions/manipulation under anesthesia (LOA/MUA). A multivariate logistic regression that accounted for differences in patient demographics and comorbidities was used to compare complication and reoperation rates, and results were reported as odds ratios (OR), with statistical significance noted for P values < 0.05. A total of 5331 consecutive patients who underwent shoulder stabilization procedures between 2007 and 2014 were identified and included. A total of 4764 patients underwent arthroscopic Bankart repair (71.6% male), 428 patients underwent open Bankart repair (68.7% male), and 139 patients underwent Latarjet (75.5% male). Over the 7-year time period, there were significant increases in the annual rates of both arthroscopic Bankart repair (2007: 9.4% vs. 2014: 15.8%, P<0.001) and Latarjet (2007: <7.91% to 20.9%, P=0.016) procedures performed. In contrast, the number of open Bankart repairs decreased (2007: 16.8% vs 2014: 11.4%, P=0.002). The odds of reoperation at 90-days, 6-months, and 1-year following the Latarjet procedure was 350% (p<0.001), 210% (p<0.001), and 250% (p<0.001) greater than arthroscopic Bankart repair. Similarly, the odds of a DVT/PE diagnosis (OR 8.2, p=0.02) was significantly greater following Latarjet as compared to arthroscopic Bankart repair. Interestingly, the odds of a postoperative SSI, nerve injury, adhesive capsulitis, or I&D were not significantly different between patients undergoing the Latarjet procedure and arthroscopic Bankart repair. The rate of utilization of Latarjet and arthroscopic Bankart repair has increased in the US in the past seven years in conjunction with increased treatment of anterior shoulder instability, while the rate of open stabilization has decreased. The odds of requiring a reoperation or developing any post-operative complication were greater following Latarjet as compared to arthroscopic Bankart repair. In contrast to historical data, the odds of post-operative SSI, nerve injury, and/or postoperative I&D in patients undergoing Latarjet were no different than that of patients undergoing arthroscopic Bankart repair.
