Rupp MC, Rutledge JC, Apostolakos JM, Dornan GJ, Quinn PM, Horan MP, Dey Hazra RO, Millett PJ. Preoperative patient factors that predict achieving the minimal clinically important difference following arthroscopic treatment of snapping scapula syndrome. J Shoulder Elbow Surg 2024; 33:1811-1820. [PMID: 38373485 DOI: 10.1016/j.jse.2024.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 12/21/2023] [Accepted: 01/01/2024] [Indexed: 02/21/2024]
Abstract
BACKGROUND The aim of this study was to define the minimal clinically important difference (MCID) values for patient-reported outcomes (PROs) after arthroscopic treatment of snapping scapula syndrome (SSS) using a distribution-based method, and to identify demographic, clinical, and intraoperative factors significantly associated with the achievement of MCID. It was hypothesized that subjective satisfaction scores after the procedure would be strongly associated with the achievement of MCID thresholds for the PROs and that pain, preoperative response to injection, and a scapulectomy in addition to bursal resection would be predictive of clinically relevant improvement. METHODS Patients who underwent arthroscopic treatment of SSS between October 2005 and September 2020 with a minimum of 2-year short-term postoperative follow-up were enrolled in this retrospective single-center study. The MCID was calculated using a distribution-based approach for the following PROs: 12-Item Short Form Health Survey (SF-12), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) pain "today" and "at worst." The association between achievement of the MCID and postoperative subjective satisfaction was investigated, and factors associated with achievement of MCID were determined using bivariate analysis. RESULTS Of a total of 190 patients assessed for eligibility, 77 patients (38.1 ± 14.3 years; 36 females) were included. Within the study population, statistically significant improvements in postoperative SF-12 physical component summary (PCS) (P < .001) and mental component summary (MCS) (P < 0.034), ASES (P < .001), QuickDASH (P < .001), SANE (P < .001), and VAS pain (P < .001) scores were observed at the minimum 2-year follow-up. The calculated MCID threshold values based on the study population were 5.0 for SF-12 PCS, 5.8 for SF-12 MCS, 11.3 for ASES, -10.5 for QuickDASH, 14.7 for SANE, 1.5 for VAS pain, and 1.7 for VAS pain at worst. Reaching the MCID was strongly associated with postoperative satisfaction (rated on a scale of 1-10). Across the PROs, younger age, favorable preoperative response to injection, partial scapuloplasty or scapulectomy, no prior surgery, and pain and function at baseline were significantly associated with attaining MCID. CONCLUSIONS Patients who underwent arthroscopic treatment for SSS experienced clinically significant improvements in functional scores, pain, and quality of life. This study demonstrated predictive roles for certain patient-specific factors and diagnostic variables for achieving MCID in PROs, which may help surgeons preoperatively assess the probability of success and manage patient expectations.

Abstract
Scapulothoracic dislocation (STD) is a rare condition consisting in the loss of anatomical relations of the scapula with the posterior chest wall. This pathological condition commonly occurs after a scapular region trauma or an upper arm distractive injury. Here-in, we present a case of STD occurring in a young male patient, and we discuss the mechanism of injury, the radiological imaging features, and how it can guide and help the orthopedist in the management.

Abstract
BACKGROUND Snapping scapula syndrome (SSS) is a rare condition that is oftentimes debilitating. For patients whose symptoms are resistant to nonoperative treatment, arthroscopic surgery may offer relief. Because of the rarity of SSS, reports of clinical outcomes after arthroscopic SSS surgery are primarily limited to small case series and short-term follow-up studies. PURPOSE To report minimum 5-year clinical and sport-specific outcomes after arthroscopic bursectomy and partial scapulectomy for SSS and to identify demographic and clinical factors at baseline associated with clinical outcomes at minimum 5-year follow-up. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients who underwent arthroscopic bursectomy and partial scapulectomy for SSS between October 2005 and February 2016 with a minimum of 5 years of postoperative follow-up were enrolled in this single-center study. Clinical outcome scores, including the 12-Item Short Form Health Survey (SF-12), American Shoulder and Elbow Surgeons (ASES) Shoulder Score, shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) score for pain, were collected at a minimum 5-year follow-up. Additionally, it was determined which patients reached the minimal clinically important difference. Bivariate analysis was used to determine whether baseline demographic and clinical factors had any association with the outcome scores. RESULTS Of 81 patients eligible for inclusion in the study, follow-up was obtained for 66 patients (age 33.6 ± 13.3 years; 31 female). At a mean follow-up of 8.9 ± 2.5 years (range, 5.0-15.4 years), all of the outcome scores significantly improved compared with baseline. These included the ASES (from 56.7 ± 14.5 at baseline to 87.2 ± 13.9 at follow-up; P < .001), QuickDASH (from 38.7 ± 17.6 to 13.1 ± 14.6; P < .001), SANE (from 52.4 ± 21.2 to 82.7 ± 19.9; P < .001), SF-12 Physical Component Summary (from 39.7 ± 8.3 to 50.3 ± 8.2; P < .001), SF-12 Mental Component Summary (from 48.2 ± 11.7 to 52.0 ± 9.0; P = 0.014) and VAS pain (from 5.2 ± 2.1 to 1.4 ± 2.0; P < .001). The minimal clinically important difference in the ASES score was reached by 77.6% of the patients. Median postoperative satisfaction was 8 out of 10. It was found that 90.5% of the patients returned to sport, with 73.8% of the patients able to return to their preinjury level. At the time of final follow-up, 8 (12.1%) patients had undergone revision surgery for recurrent SSS symptoms. Older age at surgery (P = .044), lower preoperative SF-12 Mental Component Summary score (P = .008), lower preoperative ASES score (P = .019), and increased preoperative VAS pain score (P = .016) were significantly associated with not achieving a Patient Acceptable Symptom State on the ASES score. CONCLUSION Patients undergoing arthroscopic bursectomy and partial scapulectomy for SSS experienced clinically significant improvements in functional scores, pain, and quality of life, which were sustained at a minimum of 5 years and a mean follow-up of 8.9 years postoperatively. Higher patient age, inferior mental health status, increased shoulder pain, and lower ASES scores at baseline were significantly associated with worse postoperative outcomes.

Arthroscopic scapulothoracic bursectomy with and without superomedial angle scapuloplasty: a comparison of patient-reported outcomes. J Shoulder Elbow Surg 2023; 32:1945-1952. [PMID: 37075938 DOI: 10.1016/j.jse.2023.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 03/02/2023] [Accepted: 03/22/2023] [Indexed: 04/21/2023]
Abstract
BACKGROUND Operative treatment of scapulothoracic bursitis most commonly comprises arthroscopic scapulothoracic bursectomy with or without partial superomedial angle scapuloplasty. There is currently no consensus regarding whether or when scapuloplasty should be performed. Prior studies are limited to small case series, and optimal surgical indications are not yet established. The purposes of this study were (1) to retrospectively review patient-reported outcomes of arthroscopic treatment of scapulothoracic bursitis and (2) to compare outcomes between scapulothoracic bursectomy alone and bursectomy with scapuloplasty. We hypothesized that bursectomy with scapuloplasty would provide superior pain relief and functional improvement. MATERIALS AND METHODS All cases of scapulothoracic débridement with or without scapuloplasty completed at a single academic center from 2007 through August 2020 were reviewed. Patient demographic characteristics, symptomatology data, physical examination findings, and corticosteroid injection response data were collected from the electronic medical record. Visual analog scale pain, American Shoulder and Elbow Surgeons, Simple Shoulder Test, and Single Assessment Numeric Evaluation scores were collected. Comparisons between the group undergoing bursectomy alone and the group undergoing bursectomy with scapuloplasty were made using the Student t test for continuous variables and the Fisher exact test for categorical variables. RESULTS Thirty patients underwent scapulothoracic bursectomy alone, and 38 patients underwent bursectomy with scapuloplasty. Final follow-up data were available for 56 of 68 cases (82%). Final postoperative visual analog scale pain scores (3.4 ± 2.2 and 2.8 ± 2.2, respectively; P = .351), American Shoulder and Elbow Surgeons scores (75.8 ± 17.7 and 76.5 ± 22.5, respectively; P = .895), and Simple Shoulder Test scores (8.8 ± 2.3 and 9.5 ± 2.8, respectively; P = .340) were similar between the bursectomy-alone and bursectomy-with-scapuloplasty groups. CONCLUSION Both arthroscopic scapulothoracic bursectomy alone and bursectomy with scapuloplasty are effective treatments for scapulothoracic bursitis. Operative time is shorter without scapuloplasty. In this retrospective series, these procedures showed similar outcomes regarding shoulder function, pain, surgical complications, and rates of subsequent shoulder surgery. Further studies with a focus on 3-dimensional scapular morphology may help optimize patient selection for each of these procedures.

Abstract
Snapping scapula syndrome (SSS) is a source of pain and discomfort in patients. It is not uncommon for patients who present with SSS to have some degree of scapular dysfunction, especially with the tightness of the pectoralis minor (PM) muscle. In this Technical Note, we demonstrate our preferred technique for arthroscopic scapulothoracic bursectomy and partial scapulectomy with concomitant pectoralis minor release for the treatment of symptomatic SSS and PM tightness. In the treatment of these patients, PM release is beneficial because arthroscopic scapulothoracic bursectomy or partial scapulectomy alone may result in residual scapular dyskinesis.

Abstract
Background: Snapping scapula syndrome (SSS) is a disruption of the normal smooth motion of the scapulothoracic joint leading to clicking or “snapping” which can be painful or painless. There are a variety of etiologies with first-line treatment being conservative. If patients fail extensive nonoperative treatments, then surgery may be considered. Although technically challenging, arthroscopic treatment is recommended due to its decreased morbidity and improved cosmesis. Indications: We present a 21-year-old man with a 2-year history of mechanical popping and crepitus with overhead and scapulothoracic motion of his left arm. After failing an extensive trial of conservative therapy, the patient underwent scapulothoracic arthroscopy with bursectomy and partial resection of the superomedial border of the scapula. Technique Description: The patient is positioned prone with the operative arm behind the back to elevate the medial border off the chest wall. The scapula is outlined. Two arthroscopic portals are used; the superior portal is 3 cm medial to the medial border of the scapula at the level of the scapular spine and the inferior portal is 4 cm inferior to this at the inferomedial angle of the scapula. Viewing is typically done from the inferior portal, and the superior portal is used for resection of the bursa and superomedial border of the scapula. A shaver and ablator are used to perform a bursectomy and expose the superomedial border of the scapula. An arthroscopic bur is used to partially resect the superomedial border of the scapula at approximately 3.5 cm wide and 2 cm deep. Results: Although there are limited studies examining outcomes after scapulothoracic arthroscopy, the current literature suggests that scapulothoracic arthroscopy is effective in improving crepitus, pain, and clinical outcome scores. Discussion/Conclusion: In cases of SSS which have failed exhaustive conservative therapy, arthroscopic bursectomy and partial bony resection can be an effective treatment option with minimal invasiveness, improved cosmesis, and early return to activities. Proper patient positioning and careful portal placement are critical to avoid iatrogenic injury, particularly to neurologic structures.

Abstract
» Scapular dyskinesis is an alteration of normal scapular kinematics. It is essential that each patient be evaluated holistically and that sport-related factors be taken into account. » The presentation of scapular dyskinesis may be highly variable depending on the underlying etiology or associated pathology, but the onset of symptoms is often gradual. » Sport-specific literature on scapular dyskinesis is most commonly reported in the context of baseball, swimming, and tennis. Treatment is most often conservative and involves physical therapy directed at the scapular stabilizers.

Abstract
Scapulothoracic bursitis involves inflammation of the scapulothoracic bursa caused by overuse of the shoulder or traumatic injury. Conservative management is recommended initially, and a surgical approach, such as bursectomy or scapular angle resection, is indicated later. Scapulothoracic bursitis in a patient with systemic lupus erythematosus (SLE) has been rarely reported in the literature. A 34-year-old woman was hospitalized in our hospital for a palpable mass on the right side of her back. She had a history of SLE, which was diagnosed and treated with medication 13 years prior. Chest magnetic resonance imaging (MRI) revealed fluid collection measuring 6.0 cm × 6.0 cm × 2.0 cm between the rib cage and subscapularis muscle. Histopathological examination identified the mass as bursitis with cystic degeneration. Surgical excision was performed at the infrascapular area. About 11 months later, the mass recurred in the same area. Surgical excision was again performed in the same way as before, and the same diagnosis was confirmed. Every 6 months, ultrasound examination is being conducted to assess for recurrence. The patient has not had any further complications or a relapse for the last 3 years. Prompt bursectomy can be a definitive and long-lasting treatment option for scapulothoracic bursitis accompanied by SLE.

Abstract
BACKGROUND Neurovascular anatomy has not been previously quantified for the arthroscopic snapping scapula approach with the patient in the most frequent patient position ("chicken-wing" position). The purposes of this study were (1) to determine anatomic relationships of the superomedial scapula and neurovascular structures at risk during arthroscopic surgical treatment of snapping scapula syndrome (SSS), (2) to compare these measurements between the arm in the neutral position and the arm in the chicken-wing position, and (3) to establish safe zones for arthroscopic treatment of SSS. METHODS Eight fresh-frozen cadaveric hemi-torsos (mean age, 55.8 years; range, 52-66 years) were dissected to ascertain relevant anatomic structure locations including the (1) spinal accessory nerve, (2) dorsal scapular nerve, and (3) suprascapular nerve. A coordinate measuring device was used to collect data on the relationships of anatomic landmarks and at-risk structures during the surgical approach. RESULTS The dorsal scapular nerve was a mean of 24.4 mm medial to the superomedial scapula in the neutral position and 33.1 mm medial in the chicken-wing position (P < .001); the dorsal scapular nerve was 21.7 mm medial to the medial border of the scapular spine in the neutral position and 35.5 mm medial in the chicken-wing position (P < .001). The mean distance from the superomedial angle to the spinal accessory nerve intersection at the superior scapular border was 16.5 mm in the neutral position and 15.0 mm in the chicken-wing position (P = .031). The average distance from the superomedial angle to the closest point of the spinal accessory nerve was 11.6 mm and 10.4 mm in the neutral position and chicken-wing position, respectively (P = .039). CONCLUSION Neurologic structures around the scapula vary significantly between the neutral arm position and the chicken-wing position commonly used in the arthroscopic treatment of SSS. The chicken-wing position improves safe distances for the dorsal scapular nerve during medial-portal placement and should be considered as a primary position for arthroscopic management of SSS.

Abstract
Snapping scapula syndrome (SSS) is a painful and debilitating condition that occurs as a result of disruption of normal scapulothoracic articulation and inflammation of numerous soft tissue and bursal structures that function to facilitate scapulothoracic motion. Historically, when nonoperative management of SSS failed, patients progressed to open surgical management. However, as arthroscopic techniques have evolved, the condition has been increasingly treated arthroscopically because of the minimally invasive nature, periscapular muscle-preserving approach with decreased risk to surrounding neurovascular structures, better intraoperative visualization, and quicker patient recovery and rehabilitation. The objective of this Technical Note is to describe our arthroscopic approach for the management of SSS using two portals to complete a scapulothoracic bursectomy and partial scapulectomy of the superomedial scapula. Level of Evidence: Level I: shoulder.

Abstract
Persistent pain following treatment for breast cancer is common and often imprecisely labeled as post-mastectomy pain syndrome (PMPS). PMPS is a disorder with multiple potential underlying causes including intercostobrachial nerve injury, intercostal neuromas, phantom breast pain, and pectoralis minor syndrome. Adding further complexity to the issue are various musculoskeletal pain syndromes including cervical radiculopathy, shoulder impingement syndrome, frozen shoulder, and myofascial pain that may occur concurrently and at times overlap with PMPS. These overlapping pain syndromes may be difficult to separate from one another, but precise diagnosis is essential, as treatment for each pain generator may be distinct. The purpose of this review is to clearly outline different pain sources based on anatomic location that commonly occur following treatment for breast cancer, and to provide tailored and evidence-based recommendations for the evaluation and treatment of each disorder.

Abstract
ABSTRACT Disorders of the scapulothoracic articulation can cause significant pain, as well as an audible "snapping" or crepitus in advanced cases. Although radiography, CT, and MRI are used in the diagnosis of these conditions, little is known about their manifestations on nuclear imaging. We present a case of symmetric uptake at the inferior scapulothoracic articulations mimicking metastatic disease on a staging bone scan. Recognition of this pattern of activity is not only important to accurately exclude malignancy, but also to aid referring providers in addressing potential causes of patient morbidity.

Abstract
CONTEXT Snapping scapula syndrome (SSS) is commonly misdiagnosed and underreported due to lack of awareness. OBJECTIVE This scoping review aims to summarize the current evidence related to SSS diagnosis and treatment to aid clinicians in managing the condition more effectively. DATA SOURCES PubMed, Medline, and Embase databases were searched for studies related to the etiology, diagnosis, or treatment of SSS (database inception to March 2020). STUDY SELECTION Databases were searched for available studies related to the etiology, diagnosis, or treatment of SSS. STUDY DESIGN A scoping review study design was selected to explore the breadth of knowledge in the literature regarding SSS diagnosis and treatment. LEVEL OF EVIDENCE Level 4. DATA EXTRACTION Primary outcomes abstraction included accuracy of diagnostic tests, functional outcomes, and pain relief associated with various nonoperative and operative treatment options for SSS. RESULTS A total of 1442 references were screened and 40 met the inclusion criteria. Studies commonly reported SSS as a clinical diagnosis and relied heavily on a focused history and physical examination. The most common signs reported were medial scapular border tenderness, crepitus, and audible snapping. Three-dimensional computed tomography had high interrater reliability of 0.972, with a 100% success rate in identifying symptomatic incongruity of the scapular articular surface. Initial nonoperative treatment was reported as successful in most symptomatic patients, with improved visual analogue scale (VAS) scores (7.7 ± 0.5 pretreatment, to 2.4 ± 0.6). Persistently symptomatic patients underwent surgical intervention most commonly involving bursectomy, superomedial angle resection, or partial scapulectomy. High satisfaction rates of surgery were reported in VAS (6.9 ± 0.7 to 1.9 ± 0.9), American Shoulder and Elbow Surgeons scores (50.3 ± 12.2 to 80.6 ± 14.9), and mean simple shoulder test scores (5.6 ± 1.0 to 10.2 ± 1.1). CONCLUSION Focused history and physical examination is the most crucial initial step in the diagnostic process, with supplemental imaging used to assess for structural etiologies when nonoperative management fails. Nonoperative management is as effective as surgical management in pain relief and is advised for 3 to 6 months before operative treatment.

Abstract
Background Scapulothoracic bursitis is a significant clinical condition that limits day-to-day function. Arthroscopic scapular debridement and resection have provided satisfactory outcomes; however, techniques, approaches, and recommendations remain varied. Novel bony parameters have also gained increasing interest owing to their value in preoperative planning. Purpose To assess midterm clinical outcomes after the arthroscopic management of scapulothoracic bursitis and to identify and measure novel bony parameters on preoperative magnetic resonance imaging. Study Design Case series; Level of evidence, 4. Methods A total of 8 patients underwent arthroscopic scapular debridement and bursectomy; 5 of the 8 patients underwent additional medial scapulectomy. There were 5 male (62.5%) and 3 female (37.5%) patients with a mean age of 30.1 ± 12.3 years (range, 19-58 years). Inclusion criteria for surgery were patients with symptomatic scapulothoracic bursitis for whom extensive nonoperative modalities had been utilized for at least 6 months but failed. Outcome measures included the Oxford Shoulder Score (OSS), University of California Los Angeles (UCLA) shoulder rating scale, Constant Shoulder Score (CSS), and visual analog scale (VAS) for pain. The bony parameters included scapular shape, anterior offset, costomedial angle, and medial scapular corpus angle (MSCA). Results The follow-up duration was at least 2 years for all patients (mean follow-up, 25.0 ± 4.1 months [range, 24-35 months]). The majority of patients had a concave-shaped scapula (62.5%). The mean anterior offset was 24.3 ± 3.4 mm, and the mean costomedial angle was 132.3° ± 9.6°. Half the patients had a positive MSCA, while the other half had a negative MSCA. A statistically significant improvement was observed in the OSS, UCLA, CSS, and VAS scores from preoperatively to 2-year follow-up (P < .001 for all). No complications were observed. Conclusion Arthroscopic scapular debridement and resection provided satisfactory midterm clinical outcomes for the treatment of scapulothoracic bursitis.

Prognosis After Arthroscopic Superior Medial Scapuloplasty for Snapping Scapula Syndrome Improves After a Transient Beneficial Response With an Ultrasound-Guided Subscapular Cortisone Injection. Arthroscopy 2020; 36:2965-2972. [PMID: 32888981 DOI: 10.1016/j.arthro.2020.07.024] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 07/06/2020] [Accepted: 07/15/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the prognostic value of an ultrasound-guided subscapular local anesthetic and cortisone injection in a consecutive series of patients who underwent an arthroscopic superior medial scapuloplasty for snapping scapula syndrome (SSS) and had been refractory to conservative treatment. METHODS We undertook an arthroscopic superior medial scapuloplasty on patients with a clinical diagnosis of SSS who had failed a structured physiotherapy program and had either gained a good response or no to minimal response to preoperative ultrasound-guided subscapular local anesthetic and cortisone injection. The patients were assessed preoperatively and at final follow-up with the QuickDASH and Constant scores, and their pain was assessed with a visual analog scale (VAS). RESULTS Between January 2009 and December 2016, 47 patients were included in the study, with a minimal follow-up of 2 years. There were 29 female and 18 male patients, and the mean age at the time of surgery was 27.4 years (range 15 to 61). Forty-two patients were available at final follow-up. There were 31 patients in the good response group and 11 patients in the no to minimal response group. For all patients, the mean time to follow-up was 41.8 months (range 24 to 108). There was a significant improvement after surgery in the mean QuickDASH score (from 39 to 20, P < .001) (minimal clinically important difference [MCID] 15.91) , Constant score (from 57 to 87, P < .001) (MCID 10.4), and VAS (from 6 to 2, P < .001) (MCID 3). For the good response group, there was a significant improvement after surgery in the mean QuickDASH score (from 38 to 18, P < .001) (MCID 15.91), the Constant score (from 57 to 89) (MCID 10.4), and the VAS (from 6 to 2, P < .001) (MCID 3). For the no to minimal response group, there was a significant improvement after surgery in the mean QuickDASH score (from 42 to 24, P < .01) (MCID 15.91), the Constant score (from 58 to 80, P < .002) (MCID 10.4), and the VAS (from 6 to 2, P < .01) (MCID 3). The difference in postoperative improvement of the QuickDASH and Constant scores between the good response and the no to minimal response groups was statistically significant (P < .05). CONCLUSION The results of this study suggest that arthroscopic scapuloplasty can lead to a significant improvement in pain and function in all patients with a clinical diagnosis of snapping scapula syndrome refractory to conservative treatment. Patients who gained a good transient response to a preoperative ultrasound-guided subscapular cortisone injection obtained a significantly better recovery than those who did not. A preoperative ultrasound-guided subscapular cortisone injection appeared to be of prognostic value.

Abstract
Scapulothoracic dissociation is a rare and potentially limb- and life-threatening injury, that results from high-energy trauma. Scapulothoracic dissociation has the potential to be overlooked in the acute setting, especially in the setting of polytrauma. Therefore, a careful search for this condition should be performed in all patients with high-energy shoulder girdle injuries. The goals of this article are to review the anatomy of the scapulothoracic articulation as well as the spectrum, imaging evaluation, differential diagnosis and management of scapulothoracic dissociations.

Abstract
Objectives To evaluate the results of patients undergoing arthroscopic surgical treatment for snapping scapula syndrome. Methods This is a retrospective study of 11 patients undergoing scapulothoracic arthroscopy for the treatment of snapping scapula syndrome. The study included patients with clinical diagnosis of snapping scapula syndrome who did not show pain improvement after at least six months of physical therapy. Patients were assessed using the DASH, UCLA, visual analogue pain assessment (VAS), and Short-Form 36 (SF36) scores. Results The mean age at surgery was 38.4 years (21–48). The mean duration of symptoms before surgery was 2.8 years (range 6 months to 6 years). The mean follow-up duration was 12 months (range: 6.4–28). The mean postoperative scores were: DASH, 7.8 points; VAS, 1.5 points, being ten cases (90%) of mild pain and one case (10%) of moderate pain; UCLA, 32; and SF-36, 79.47. Conclusions The arthroscopic approach for the treatment of snapping scapula syndrome presents excellent functional results.

Abstract
Background Snapping scapula syndrome, also known as scapulothoracic crepitus or bursitis, is a manifestation of a mechanical abnormality of the scapulothoracic joint. In addition to characteristic findings on physical examination, magnetic resonance imaging (MRI) exquisitely reveals soft tissue changes such as muscle edema and scapulothoracic bursitis. Case Report We present a case of a 10-year-old boy who had snapping scapula syndrome of the right scapula that was associated with edema of the serratus anterior muscle at the scapulothoracic interface and with scapulothoracic, specifically supraserratus, bursitis on MRI. Conclusions MRI in snapping scapula syndrome, which is a clinical diagnosis, exquisitely reveals soft tissue changes such as muscle edema and scapulothoracic bursitis. Such soft tissue findings of snapping scapula syndrome need to be kept in mind while evaluating routine shoulder and/or scapular region MRI, especially in the absence of relevant clinical information at the time of the imaging study.

Abstract
Symptomatic scapulothoracic disorders, including scapulothoracic crepitus and scapulothoracic bursitis are uncommon disorders involving the scapulothoracic articulation that have the potential to cause significant patient morbidity. Scapulothoracic crepitus is the presence of a grinding or popping sound with movement of the scapula that may or may not be symptomatic, while scapulothoracic bursitis refers to inflammation of bursa within the scapulothoracic articulation. Both entities may occur either concomitantly or independently. Nonetheless, the constellation of symptoms manifested by both entities has been referred to as the snapping scapula syndrome. Various causes of scapulothoracic crepitus include bursitis, variable scapular morphology, post-surgical or post-traumatic changes, osseous and soft tissue masses, scapular dyskinesis, and postural defects. Imaging is an important adjunct to the physical examination for accurate diagnosis and appropriate treatment management. Non-operative management such as physical therapy and local injection can be effective for symptoms secondary to scapular dyskinesis or benign, non-osseous lesions. Surgical treatment is utilized for osseous lesions, or if non-operative management for bursitis has failed. Open, arthroscopic, or combined methods have been performed with good clinical outcomes.

Arthroscopic management of snapping scapula syndrome improves pain and functional outcomes, although a high rate of residual symptoms has been reported. Knee Surg Sports Traumatol Arthrosc 2018; 26:221-239.

Abstract
PURPOSE To investigate the use of arthroscopy in the management of patients with snapping scapula syndrome, including aetiology, surgical decision-making, outcomes, complications, effectiveness of arthroscopy, and quality of evidence of the existing literature. METHODS Three databases (PubMed, Ovid [MEDLINE], and EMBASE) were searched independently and in duplicate to systematically screen the literature. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist guided the reporting and data abstraction. Methodological quality of all included papers was assessed using the MINORS criteria. The results are presented in a narrative summary fashion using descriptive statistics including means, proportions, and ranges. RESULTS Overall, 18 studies (5 case reports and 13 case series; all level IV evidence) were identified, including 201 patients (203 shoulders). The mean follow-up period was 32.7 months (range 1-154 months). Surgical decision-making for the use of arthroscopy was most commonly based on a failed trial of initial non-operative management in 17 studies (94%). Overall, 21% of cases achieved complete resolution of pre-operative symptoms, including pain, crepitus, and range of motion, while 68% of cases obtained some clinical improvement, but reported some residual symptoms (persistent crepitus [12%] and persistent scapulothoracic pain [4%]). Moreover, poor outcomes were reported 11% of cases and the most common complication was scapular oedema (6%). CONCLUSION Arthroscopic management of snapping scapula syndrome yields improvement in pain, crepitus, and range of motion in a majority of patients; however, most patients experience residual symptoms. Further studies are needed to compare the outcomes of shoulder arthroscopy with other available treatment options for snapping scapula syndrome. Shoulder arthroscopy for snapping scapula can improve patients' symptoms; however, patients must be informed about the high likelihood of persistent symptoms post-operatively. LEVEL OF EVIDENCE Systematic review of Level IV studies.

OBJECTIVES To evaluate the efficacy of ultrasound-guided interscalene nerve block using an ultralow volume of local anesthetic (5 mL of ropivacaine, 0.75%) for the management of post-thoracotomy shoulder girdle pain. DESIGN Open-cohort, prospective, single-center study. SETTING University hospital. INTERVENTIONS Patients with post-thoracotomy shoulder girdle pain (visual analog scale [VAS] ≥5) received an ultrasound-guided interscalene nerve block. MEASUREMENTS AND MAIN RESULTS Thirty minutes after block implementation, the VAS was used to quantify pain across the shoulder girdle. The index (I) was calculated to indicate improvement of pain as follows: [Formula: see text] Nerve bocks resulting in I ≥75% were considered excellent. Total tramadol consumption 36 hours after nerve blocks, patients' satisfaction, and complications related to the procedure also were assessed. Patients were segregated in the following 2 groups: group A, which comprised patients with pain in the shoulder area (glenohumeral and acromioclavicular joints) (n = 30), and group B, which comprised patients with pain in the scapula (n = 17). I was significantly greater in group A (88.3% ± 14%) than in group B (43.2% ± 22%). In groups A and B, 90% and 11% of patients, respectively, demonstrated excellent pain control. Total tramadol consumption in group A, 25 (0-100) mg, was significantly less that of group B, 250 (150-500) mg. Patients' satisfaction also was significantly higher in group A compared with group B. No complications were recorded. CONCLUSIONS Ultrasound-guided interscalene nerve block can substantially alleviate post-thoracotomy pain in the shoulder but not in the scapular area.

Abstract
Introduction: Patients with scapulothoracic syndrome present with pain in the scapulothoracic area aggravated by overhead and repetitive shoulder movements. The aim of our study was to assess the outcome of scapulothoracic arthroscopic treatment in patients with painful snapping scapula in our institution. Methods: Fourteen patients underwent scapulothoracic arthroscopic treatment for painful snapping scapula. Pre-operatively, all these patients had a trial of conservative treatment modalities for at least 6 months. Two portals along the medial border of scapula were used for arthroscopy and instrumentation. In three cases a superior portal was also used. The arm was placed in the “chicken wing” position so that the scapula lifted up from the chest wall. Outcome was assessed using pre and postoperative pain visual analogue score and Oxford Shoulder Score. Results: Of the fourteen patients included in our study, ten were female and four were male patients. Mean age at the time of surgery was 27.6 years. Mean follow up was 35.7 months. Pain visual analogue score improved significantly from a mean of 8.8 preoperatively to 2.5 postoperatively (P value 0.00002). There was also a significant improvement in Oxford Shoulder Score from a mean of 10.8 to 40.9 (P= 0.00001). Mean crepitus score significantly decreased from 2.6 to 0.21 (p < 0.00001). Crepitus completely resolved in eleven patients. In three there was residual palpable crepitus but they had good pain relief. Conclusion: Arthroscopic scapulothoracic treatment provides significant pain relief and functional improvement for painful snapping scapula symptoms not responding to non-surgical treatment modalities.

Abstract
OBJECTIVE The purpose of this article is to determine the osseous morphology of snapping scapulae on CT images. MATERIALS AND METHODS Retrospectively, 2D and 3D CT images of the scapulae of 35 patients with snapping scapula were compared with 35 age-matched control group subjects. Two observers analyzed the following parameters: presence of the Luschka tubercle; abnormalities of the bones and periscapular soft tissues; shape, thickness, and length of the superior angle of the scapula; craniocaudal length of the scapula; minimum distance between the scapula and rib cage; depth of the subscapular fossa; and the superomedial angle. RESULTS In patients with snapping scapulae, observer 1 did not find any Luschka tubercles, whereas observer 2 detected one; in the control group both observers found two Luschka tubercles (p > 0.49). One scapular osteochondroma was found in the group with snapping scapulae. No further abnormalities of the rib cage or periscapular soft tissues were found in that group. The superior angle of the scapula was significantly thicker in the snapping scapula group compared with the control group (4.8 ± 1.3 mm vs 4.0 ± 1.0 mm, p < 0.012). The subscapular fossa was significantly deeper in patients with snapping scapula than in control group subjects (25.7 ± 5.2 mm vs 21.8 ± 5.0 mm, p < 0.005). The remaining parameters did not differ significantly between the groups. CONCLUSION The Luschka tubercle was rarely observed and not associated with a snapping scapula. However, the superior angle of the scapula was significantly thicker and the subscapular fossa was significantly deeper in patients with snapping scapula than in control group subjects.

Abstract
Scapulothoracic dissociation is a rare, potentially limb- and life-threatening injury of the shoulder girdle. The injury is characterized by lateral displacement of the scapula resulting from traumatic disruption of the scapulothoracic articulation. The typical physical examination findings consist of substantial swelling of the shoulder girdle, along with weakness, numbness, and pulselessness in the ipsilateral upper extremity. Radiographic evaluation includes measurement of the scapular index on a nonrotated chest radiograph and assessment for either a distracted clavicle fracture or a disrupted acromioclavicular or sternoclavicular joint. Although vascular injury occurs in most patients, emergent surgery is performed only in patients with either limb-threatening ischemia or active arterial hemorrhage. Management of neurologic injury can be delayed if necessary. The location and severity of neurologic injury determine whether observation, nerve grafting, nerve transfer, or above-elbow amputation is performed. Skeletal stabilization procedures include plate fixation of clavicle fractures and reduction of distracted acromioclavicular or sternoclavicular joints. The extent of neurologic injury determines clinical outcomes. Medical Outcomes Study 36-Item Short Form scores are significantly lower in patients with complete brachial plexus avulsion injury than in patients with postganglionic injury.

Abstract
BACKGROUND Snapping scapula syndrome (SSS) is caused by bony and/or soft tissue impingement in the scapulothoracic articulation. Surgical resection of the superomedial angle (SMA) plus bursectomy can provide relief in most cases; however, the amount needed to achieve adequate scapulothoracic space decompression (SSD) is unknown. PURPOSE The aim of this study was to evaluate the effectiveness of partial scapulectomy and the influence of bony anatomy on SSD. It was hypothesized that the anterior offset and costomedial angle would correlate with the amount of bony resection needed to achieve adequate SSD. STUDY DESIGN Controlled laboratory study. METHODS Twenty pairs (n = 40) of shoulder specimens (mean age, 58 years [range, 41-64 years]; 10 male and 10 female specimens) were included. The scapula shape, medial scapula corpus angle (MSCA), anterior offset, and costomedial angle were obtained from computed tomography scans. Specimens were dissected, and each bare bony scapula was rigidly mounted. Points were collected using a 3-dimensional measuring arm. An SMA point and theoretical resection points (incremental 1-cm points up to 3 cm) proceeding laterally and medially were collected. The scapular plane was interpolated using points from the posterior scapular body. The horizontal distances of the anterior offset and each resection point to the scapular plane were calculated. The difference between the native anterior offset and the offset after resection represented the SSD. Adequate SSD was set at 5 mm. One-way analyses of variance and Pearson correlations were used with statistical significance set at P < .05. RESULTS The maximum SSD with 3-cm resection was significantly correlated with the anterior offset ( R = 0.83, P < .001) as well as the costomedial angle ( R = -0.43, P = .006) but not the MSCA ( R = -0.11, P = .495) or scapula shape ( F2,37 = 0.39, P = .681). For the 5 scapulae with an anterior offset of less than 20 mm, a 5-mm SSD was not achieved. For 18 of 30 (60%) scapulae with an anterior offset between 20 mm and 35 mm, 3-cm resection provided at least a 5-mm SSD. For the 5 scapulae with an anterior offset of greater than 35 mm, 2-cm resection resulted in at least a 5-mm SSD in all cases. CONCLUSION The anterior offset of the scapula appeared to be the most important bony parameter to consider during preoperative planning and the evaluation of SSD with partial scapulectomy. CLINICAL RELEVANCE The results of this study may help surgeons with preoperative planning of surgical decompression of the scapulothoracic space for patients with symptomatic SSS.

Abstract
PURPOSE To investigate clinical outcomes after primary and revision arthroscopic treatment for snapping scapula syndrome (SSS) and identify predictive factors associated with outcomes. METHODS Patients who underwent arthroscopic treatment for SSS between October 2005 and December 2013 were identified in a prospectively collected database. The inclusion criteria were patients with a diagnosis of symptomatic SSS, in whom extensive nonoperative modalities failed, who underwent arthroscopic surgery for SSS, and who had undergone surgery a minimum of 2 years earlier. Postoperative clinical outcomes were assessed with the American Shoulder and Elbow Surgeons score; short version of the Disabilities of the Arm, Shoulder and Hand questionnaire; and general health Short Form 12 (SF-12) scores, including both physical component summary and mental component summary. Patient satisfaction was recorded on a 10-point visual analog scale. Scapular bony morphology was determined on preoperative magnetic resonance imaging. RESULTS Ninety-two scapulae underwent arthroscopic treatment for SSS. There were 74 scapulae that met the inclusion criteria, including having undergone surgery a minimum of 2 years earlier. An outcome questionnaire was completed for 60 of 74 (81%). The mean age was 33 years (range, 12-65 years), and the mean duration of symptoms before surgery was 4 years (range, 90 days to 20.4 years). The mean follow-up period was 3.4 years (range, 2-7 years). Eight scapulae failed initial surgical management (10.9%) because of recurrent pain and underwent revision surgery at a mean of 309 days (range, 120-917 days). After surgery, there was a significant improvement in all outcome scores, including SF-12 physical component summary score, from 39.2 to 45.4 (P = .002); SF-12 mental component summary score, from 45.0 to 49.6 (P = .023); American Shoulder and Elbow Surgeons score, from 52.6 to 75.8 (P < .001); and score on the short version of the Disabilities of the Arm, Shoulder and Hand questionnaire, from 40.2 to 24.2 (P = .001). The median patient satisfaction rating was 7 of 10. Greater age, lower preoperative psychological score, and longer duration of symptoms before surgery correlated with lower postoperative outcome scores. CONCLUSIONS Arthroscopic surgery is an effective treatment for SSS in both primary and revision cases, showing significant improvements in all postoperative outcome scores at a mean of 3.4 years. Lower preoperative mental status score, longer duration of symptoms, and greater age were associated with poorer outcomes. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Snapping scapula syndrome is a rare condition caused by the disruption of the gliding articulation between the anterior scapula and the posterior chest wall. The etiology of snapping scapula syndrome is multifactorial, and contributing factors include scapular dyskinesis, bursitis from repetitive use or trauma, and periscapular lesions. Although the majority of cases are initially treated with nonoperative modalities, recalcitrant snapping scapula syndrome can warrant surgical management. This report describes a 34-year-old amateur weight lifter with a 1-year history of increasing pain and fullness over his posterior shoulder region. He reported full shoulder motion associated with an audible, palpable, and painful crepitus, exacerbated with overhead movement and wall pushups. Previous periscapular stabilization exercises and corticosteroid injection yielded minimal resolution of his symptoms. Prior to being referred to the authors' clinic, the patient was evaluated at an outside facility and deemed a suboptimal candidate for arthroscopic bursectomy because of the large size and location of this lesion. Magnetic resonance imaging showed a large polylobulated fluid collection causing scapulothoracic distention. There was no evidence of osseous abnormalities originating from the scapular body. Computed tomography-guided placement of methylene blue and contrast dye was used to facilitate localization and, in an effort to minimize recurrence, ensure the complete removal of bursal tissue. During 8 weeks, this patient recovered unremarkably and returned to full-duty activities with resolution of symptoms. The authors present the management of chronic and recalcitrant snapping scapula syndrome, and report the open excision of the largest scapulothoracic bursal lesion described, to their knowledge, in the English literature.

Abstract
BACKGROUND Resection of the medial upper corner of the scapula is one option for treating patients with a painful chronic snapping scapula. However, the degree to which this procedure results in sustained relief of pain during long-term followup, and whether surgical treatment offers any compelling advantages over nonsurgical approaches at long-term followup, are not known. QUESTIONS/PURPOSES We asked: (1) At long-term followup after surgical treatment of a painful snapping scapula, did patients' pain decrease? (2) Did scapulocostal crepitation improve? (3) Did patients return to work? METHODS Between 1971 and 1992, 15 patients underwent surgery by one surgeon for persistent (> 1 year) and severely painful crepitus around the superomedial scapula that did not respond to nonsurgical approaches. The procedure consisted of an open resection of the superomedial corner of the scapula and release of the levator scapulae muscle. Patients treated surgically were compared with a group of nine patients treated nonsurgically between 1975 and 1997; their treatments included temporary physiotherapy, massage, and NSAIDs. In general, the patients treated nonsurgically presented with less pain. However, during much of this study period, objective pain and functional scales were not in common use, and so baseline scores were not available. Of the 15 patients treated surgically, nine participated in a clinical and questionnaire survey at a mean of 22 years (range, 16-35 years), and 12 participated in a questionnaire survey a mean 27 years after surgery (range, 23-43 years). Of the nine patients treated nonsurgically, seven participated in a clinical followup and questionnaire survey at a mean followup of 16 years (range, 10-25 years), and all nine completed a questionnaire survey at a mean of 22 years (range, 17-33 years). Patient age at onset of symptoms was a mean of 27 years. The clinical followup and questionnaires focused on pain, crepitation, and work status. RESULTS With the numbers available, there was no difference in pain scores between patients treated surgically and those treated nonsurgically (mean VAS pain with exertion 0.8 ± 1.3 versus 1.5 ± 1.6; p = 0.357); in fact, pain scores were quite low in both groups. Pain improved promptly in seven of 12 patients treated surgically, but lasted for at least several years in all patients treated nonsurgically. Crepitus persisted variably in both groups at final followup, with no apparent difference between the groups in terms of its frequency, but it was not consistently associated with pain at final followup in either group (six of 12 patients treated surgically, all painless; and all of seven clinically examined patients treated nonsurgically, two without pain, had crepitus at latest followup; p = 0.004), whereas at initial presentation, the crepitus had been painful in all patients. All patients in both groups had returned to work after surgery or the first consultation. CONCLUSIONS Carefully selected patients who undergo this procedure appear to obtain sustained relief of painful crepitus at long term, but so do patients treated nonsurgically. Since the decision to treat these patients surgically was somewhat subjective, and since patients treated nonsurgically did so well (although the surgically treated patients improved faster), we cannot conclude that surgery is better than nonsurgical treatment. Multicenter comparative studies with carefully applied indications are needed. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Snapping scapula syndrome at the superomedial corner of the scapula can lead to significant shoulder dysfunction. Bursectomy with or without partial scapulectomy is currently the most beneficial primary method of treatment in patients in whom nonoperative therapy fails. Arthroscopic access to the scapulothoracic space is simple and reproducible with the technique described in this report. The bursal tissue can be cleared, optimizing visualization of the scapulothoracic space and the anatomic structures. Arthroscopic decompression of the scapulothoracic bursa and resection of the superomedial corner of the scapula are highlighted in a video example.

Abstract
HYPOTHESIS AND BACKGROUND Scapular incongruity has been described as a contributing factor to the development of snapping scapula syndrome (SSS). The purpose of this retrospective case-control study was to determine the association between scapula bony morphology on magnetic resonance imaging (MRI) and the diagnosis of SSS. METHODS Bony morphologies of the scapula were evaluated on MRI scans of 26 patients with SSS and 19 patients with non-SSS pathologies. The medial scapula corpus angle (MSCA) was measured on axial MRI sequences. Scapulae were categorized as straight, S shaped, or concave. Two independent observers performed the measurements. Interobserver and intraobserver agreements of MSCA measurements were determined with intraclass correlation coefficients. RESULTS Axial scapula bony morphology identified 28 scapulae of the straight type, 14 S-shaped scapulae, and 5 concave scapulae. All 5 concave scapulae had confirmed SSS. Measurement of the MSCA showed excellent interobserver agreement of 0.80 (95% confidence interval [CI], 0.67 to 0.89) and intraobserver agreement of 0.70 (95% CI, 0.52 to 0.82). There were significant differences in the mean MSCAs between shoulders with SSS (14.4° ± 19.3°) and non-SSS shoulders (-3.3° ± 15.3°, P = .001). The odds ratio was 8.4 (95% CI, 2.2 to 31.8) for positive MSCA and SSS. The scapulothoracic distance was significantly decreased in the SSS group (14.9 ± 5.8 mm) compared with the non-SSS patients (24.0 ± 6.7 mm, P < .001). DISCUSSION AND CONCLUSION Anterior angulation of the medial scapula in the axial plane was associated with SSS. Patients with a concave-shaped scapula and a positive MSCA have a 12-fold increased risk of SSS. The MSCA may prove helpful in determining the location and amount of scapular resection needed for patients with SSS.
