Clinical Outcomes Following Arthroscopic Decompression and Repair versus Repair Alone in Patients with a Concomitant Spinoglenoid Cyst and SLAP Lesion: A Systematic Review. Diagnostics (Basel) 2023; 13:2364. [PMID: 37510107 PMCID: PMC10378101 DOI: 10.3390/diagnostics13142364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 07/06/2023] [Accepted: 07/12/2023] [Indexed: 07/30/2023] Open
Abstract
(1) Background: Patients with a superior-labrum-from-anterior-to-posterior (SLAP) tear associated with a spinoglenoid ganglion cyst have undergone various procedures. The purpose of this study is to evaluate clinical outcomes following arthroscopic treatment in patients with a concomitant spinoglenoid ganglion cyst and SLAP lesion. (2) Methods: This study followed PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines, utilizing the PubMed, EMBASE, Cochrane Library, and Scopus databases. The keywords included shoulder, SLAP, labral tear, spinoglenoid notch, paralabral cyst, arthroscopy, and treatment. (3) Results: A total of 14 articles (206 patients) were included. Repair alone was administered in 114 patients (Group R), and 92 patients underwent additional cyst decompression (Group RD). Both groups showed excellent and similar clinical scores. The rate of the complete resorption of the cyst was 95.5% in Group RD, and 92.2% in Group R. The complication rate was 3.5% in Group RD, and 11.4% in Group R. The reoperation rate was 0% in Group RD, and 5.3% in Group R. (4) Conclusion: Reliable clinical outcomes without serious complications were obtained from the use of both procedures. The decompression of the cyst is a safe method that will alleviate pressure on the suprascapular nerve.

Comparisons between treatment of isolated posterosuperior paralabral cysts and simultaneous treatment of cysts combined with associated shoulder pathologies: arthroscopic treatment of posterosuperior paralabral cysts. Arch Orthop Trauma Surg 2023; 143:665-675.

Abstract
INTRODUCTION The purpose of this study is to report the radiologic and clinical outcomes of arthroscopic intervention for isolated posterosuperior paralabral cysts and simultaneous treatment of cysts combined with associated shoulder pathologies. MATERIALS AND METHODS From March 2008 through December 2016, 70 cases (48 males and 22 females) operated on for symptomatic posterosuperior paralabral cysts were included. Mean age was 45 (range 18-69). These patients were classified into two groups depending on if they had accompanying lesions: Group I (isolated group, 27 patients) and Group II (concomitant group, 43 patients). Arthroscopic cyst decompression with a labral repair or posterior capsulotomy for patients without labral tear were performed. All concomitant pathologies were also operated simultaneously. Follow-up MRI were performed at postoperative 6 months and clinical outcomes were evaluated during the follow-up. RESULTS Arthroscopic all intra-articular cyst decompression and labral repair was performed on 67 patients. In three patients, posterior capsulotomy without labral repair was performed for cyst removal. For 43 patients with concomitant lesions, 31 rotator cuff repairs, three SLAP repairs along with biceps tenodesis, two distal clavicle resections due to A-C joint arthritis, one calcific deposit removal, four Bankart repairs, and two acromioplasties were performed. The follow-up MRI showed complete cyst resorption except for two patients. The mean VAS, ASES, UCLA, SST and CS scores significantly improved at the last follow-up. Although both groups showed significantly improved range of motion after the surgery, improvement of ROM in Group II lagged at early periods of the rehabilitation. CONCLUSIONS Arthroscopic labral repair with all intra-articular cysts decompression or simple posterior capsulotomy were both effective treatment modalities. If paralabral cysts were associated with other shoulder lesions, simultaneous treatment of combined lesions could be performed for the improved clinical outcomes at final follow-up with expected lag in the early rehabilitation period.

Abstract
OBJECTIVE To undertake differential diagnosis of scapular bone defects found in two medieval skeletons buried in different necropoles of Friuli Venezia Giulia (Italy) and to evaluate the clinical significance of paralabral cysts in the context of shoulder pathology. MATERIALS Individual JoT36 is an adult male exhumed from a necropolis belonging to a rural agricultural settlement dated to the 10th to 11th century A.D. Individual CIVT58 is an adult male from a Langobard necropolis dated to 630-670 A.D. METHODS Macroscopic examination of the skeletons was performed using standard osteological methods and review of pertinent clinical literature to assist differential diagnosis. RESULTS Between the glenoid cavity and the spinoglenoid notch of the right scapula of JoT36 there is a multilocular circular defect adjacent to the glenoid rim. On the neck of the left scapula of CIVT58, immediately above the spinoglenoid notch, there is a unilocular circular depression. In both cases, the cortical bone appears smooth without any evidence of erosion or sclerosis. CONCLUSIONS Skeletal findings and historical/archaeological contexts of both cases are compatible with the diagnosis of paralabral cysts. SIGNIFICANCE Paralabral cysts are relatively frequently observed in clinical settings but very few examples have been documented in paleopathological literature. This study seeks to improve recognition and interpretation of this pathology in historical/archaeological contexts. LIMITATIONS Findings from a case report can neither generate epidemiological information nor be generalized. SUGGESTIONS FOR FURTHER RESEARCH Identification of new cases may add valuable information about lifestyles and related shoulder pathologies in ancient times.

Abstract
Suprascapular nerve entrapment syndrome (SNES) is an often-overlooked etiology of shoulder pain and weakness. Treatment varies depending on the location and etiology of entrapment, which can be described as compressive or traction lesions. In some cases, treating the primary cause of impingement (ie. rotator cuff tear, ganglion cyst, etc.) is sufficient to relieve pressure on the nerve. In other cases where impingement is caused by dynamic microtrauma (as seen in overhead athletes and laborers), treatment is often more conservative. Conservative first-line therapy includes rehabilitation programs, nonsteroidal anti-inflammatory drugs, and lifestyle modification. Physical therapy is targeted at strengthening the rotator cuff muscles, trapezius, levator scapulae, rhomboids, serratus anterior, and deltoid muscle(s). If non-operative treatment fails to relieve suprascapular neuropathy, minimally invasive treatment options exist, such as suprascapular nerve injection, neurostimulation, cryoneurolysis, and pulsed radiofrequency. Multiple treatment modalities are often used synergistically due to variations in shoulder anatomy, physiology, pain response, and pathology as a sole therapeutic option does not seem successful for all cases. Often patients can be treated with non-invasive measures alone; however, injuries refractory to conservative treatment may require either arthroscopic or open surgery, particularly if the patient has an identifiable and reversible cause of nerve compression. Indications for invasive treatment include, but are not limited to, refractory to non-operative treatment, have a space-occupying lesion, or show severe signs and symptoms of muscle atrophy. Open decompression has fallen out of favor due to the advantages inherent in the less invasive arthroscopic approach.

Abstract
PURPOSE To report clinical outcomes following arthroscopic suprascapular nerve (SSN) decompression for suprascapular neuropathy at the suprascapular and/or spinoglenoid notch in the absence of major concomitant pathology. METHODS We retrospectively reviewed prospectively collected data of 19 patients who underwent SSN release at the suprascapular and/or spinoglenoid notch between April 2006 and August 2017 with ≥2 years of follow-up. Patients who underwent concomitant rotator cuff or labral repairs or had severe osteoarthritis were excluded. Pre- and postoperative strength and patient-reported outcomes were collected, including the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numerical Evaluation (SANE), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), 12-item Short Form (SF-12), and satisfaction. Complications and revisions were recorded. RESULTS At a mean final follow-up of 4.8 years, pre- to postoperative ASES (64.9 ± 18.7 versus 83.5 ± 23.1; P = .018), QuickDASH (28.7 ± 17.2 versus 12.7 ± 17.1; P = .028), SANE (64.3 ± 16.4 versus 80.8 ± 22.3; P = .034), and SF-12 PCS (41.1 ± 10.8 versus 52.3 ± 5.8; P = .007) scores all significantly improved. Median strength for external rotation improved significantly (4 [range 2 to 5] versus 5 [range 3 to 5]; P = .014). There was no statistically significant improvement in median strength for abduction (4 [range 3 to 5] versus 5 [5]; P = .059). Median postoperative satisfaction was 9 (range 1 to 10), with 8 patients (50%) rating satisfaction ≥9. No complications were observed, and no patients went on to revision surgery. CONCLUSION Arthroscopic SSN decompression for suprascapular neuropathy at the suprascapular and/or spinoglenoid notch in the absence of major concomitant glenohumeral pathology results in good functional outcomes with significant improvements from before to after surgery.

Abstract
Suprascapular neuropathy is an uncommon but increasingly recognized cause of shoulder pain and dysfunction due to nerve entrapment. The aim of this review is to summarize some important aspects of this shoulder pathology. An extensive research was performed on PubMed and Clinical Key. The goal was to collect all the anatomical, biomechanical and clinical studies to conduct an extensive overview of the issue. Attention was focused on researching the state of art of the diagnosis and treatment. A total of 59 studies were found suitable and included. This condition is more frequently diagnosed in over-head athletes or patients with massive rotator cuff tears. Diagnosis may be complex, whereas its treatment is safe, and it has a great success rate. Prompt diagnosis is crucial as chronic conditions have worse outcomes compared to acute lesions. Proper instrumental evaluation and imaging are essential. Dynamic compression must initially be treated non-operatively. If there is no improvement, surgical release should be considered. On the other hand, soft tissue lesions may first be treated non-operatively. However, surgical treatment by arthroscopic means is advisable when possible as it represents the gold standard therapy. Other concomitant shoulder lesions must be recognized and treated accordingly.

Abstract
INTRODUCTION Spinoglenoid cysts are a rare cause of suprascapular neuropathy of compressive etiology in which the patient may present with shoulder pain and muscle hypotrophy. MRIs are the imaging modality of choice showing location, size, and extent of the lesion for preoperative assessment. Currently, surgical intervention is the preferred approach for the management of a spinoglenoid cyst with arthroscopy being favored over the open technique. CASE PRESENTATION A 25-year-old male patient presenting with right posterior shoulder pain and decreased range of motion associated with the development of progressive weakness of the supraspinatus and infraspinatus muscles. Right shoulder MRI showed a posterior tear of the glenoid labrum and a spinoglenoid ganglion cyst. Preoperative electroneuromyography was suggestive of a suprascapular nerve impairment. FOLLOW-UP Six months postoperatively, the patient has regained full range of motion of his right shoulder with no residue signs of muscle hypotrophy. CONCLUSION Spinoglenoid cysts can cause compressive neuropathy with associated pain and muscle hypotrophy. MRI and EMG can help in establishing the diagnosis and in the pre-operative assessment. Surgical intervention with arthroscopy is currently the technique preferred by most surgeons.

Abstract
Muscle atrophy in shoulders with rotator cuff tendon tears is a negative prognosticator, associated with decreased function, decreased reparability, increased retears after repair, and poorer outcomes after surgery. Muscle edema or atrophy within a neurologic distribution characterizes denervation. Because most nerve entrapments around the shoulder are not caused by mass lesions and show no nerve findings on routine MR imaging sequences, pattern of muscle denervation is often the best clue to predicting location of nerve dysfunction, which narrows the differential diagnosis and guides clinical management. The exception is suprascapular nerve compression in the spinoglenoid notch caused by a compressing cyst.

Abstract
Introduction: Entrapment of the suprascapular nerve is an uncommon but important differential in patients who present with posterior shoulder pain. Frequently misdiagnosed as rotator cuff or cervical disc disease, this increasingly recognized entity can result from traction-related or compression-related etiology. Two sites of compression include the suprascapular and spinoglenoid notches with the latter less commonly encountered. Case Report: In our study, we describe a case of arthroscopic decompression of suprascapular nerve entrapment at the spinoglenoid notch due to hypertrophied spinoglenoid ligament using an improvised arthroscopic technique. Conclusion: Spinoglenoid notch compression of the suprascapular nerve is an important cause of posterior shoulder pain with infraspinatus wasting. A clear understanding of the nerve anatomy and the common site of compression allow for accurate diagnosis. The modified arthroscopic technique described is easily reproducible and provides good visualization of the anatomy, allowing adequate and safe decompression of the suprascapular nerve.

Abstract
Paralabral cysts are an increasingly recognized cause of suprascapular nerve (SSN) impingement, often causing insidious weakness in the rotator cuff. Compression at the suprascapular notch is often due to the presence of a SLAP tear and leads to pain, weakness, and atrophy of both the supraspinatus and infraspinatus muscles. Compression of the SSN at the spinoglenoid notch leads to weakness and atrophy of the infraspinatus only. Arthroscopic decompression of cysts with repair of labral pathology is typically performed in a sublabral fashion, which may make visualization of the extent of the cyst difficult and places the SSN at increased risk. With any approach, an intimate knowledge of the anatomy of the SSN is vital to safe decompression. We present a surgical technique for decompression of paralabral cysts using an intra-articular transcapsular approach. This approach maximizes visualization and efficiency and reduces possible damage to the SSN.

Abstract
PURPOSE To determine if cyst management is necessary in the setting of SLAP lesions with concomitant paralabral ganglion cysts. METHODS We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, including all studies that met inclusion criteria from January 1975 to July 2015. We included patients with a SLAP II-VII lesion and a concomitant paralabral ganglion cyst who underwent arthroscopic labral repair with or without cyst decompression. Patients with follow-up of less than 3 months, a SLAP I lesion, or who underwent concomitant cuff repair were excluded. The Methodological Index for Non-randomized Studies (MINORS) scoring system was used to quantify the potential bias in each study. Outcome measures reported were provided in a table format and a subjective analysis was performed. RESULTS Nineteen studies were included yielding a total of 160 patients: 66 patients treated with repair alone [R] and 94 patients with additional cyst decompression or excision [R+D]. The VAS, Rowe, and Constant scores were excellent and similar in both groups. The mean VAS was 0.6 in [R] and ranged between 0 and 2 in [R+D] (0.5, 0, 2, 0.2). The mean Rowe scores were 94 and 98 in [R] and 95 in [R+D]. The mean Constant scores were 97 in [R] and ranged between 87 and 98 in [R+D] (98, 87, 92, 94). In total, 5 of 90 patients were unable to return to work and 2 of 45 were unable to return to sport. All 15 patients who had follow-up electromyographies displayed resolution, and in the 115 patients with follow-up MRIs, 12 did not have complete resolution of the cyst. CONCLUSIONS Despite the lack of high-quality evidence, the studies subjectively analyzed in this review suggest that both groups have excellent results. The results do not show any advantages from performing decompression. LEVEL OF EVIDENCE Level IV, systematic review of Level II and Level IV studies.

Abstract
BACKGROUND Paralabral cysts emanating from posterosuperior labral tears may compress the suprascapular nerve and induce neuropathy. This study prospectively assessed patients with labral tears and symptomatic paralabral cysts treated with isolated labral repair. Pain relief, time to cyst resolution, reversibility of muscular edema, atrophy, fatty infiltration, and bone erosion were evaluated. METHODS Forty-seven patients with symptomatic posterosuperior paralabral cysts were treated with isolated labral repair. Magnetic resonance imaging (MRI) was repeated 6 and 12 weeks postoperatively or until cyst resolution. In a subgroup of 15 patients, MRI was performed the day before the operation, the first postoperative day, and at 2 weeks. RESULTS Median cyst size was 6.8 cm3 (range, 2.1-88.9; standard deviation [SD], 18.3 cm3). Preoperatively, 20 patients (43%) presented clinical muscle atrophy and radiologic edema on MRI, 8 had fatty infiltration, and 3 presented bony scapular erosion caused by cyst compression. Median time to cyst resolution and regression of muscular edema was 11 weeks (range, 3-20; SD, 8.8 weeks) and 14 weeks (range, 3-52; SD 10.6 weeks), respectively. Preoperative fatty infiltration grade I and II of the supraspinatus and infraspinatus muscles was reduced in two patients. Bony erosions remodeled after cyst resolution. Mean pain ratings (1-10 scale) improved from 7.7 (SD, 1.8) to 1.3 (SD, 1.3; 95% confidence interval of difference, 5.5-6.8; P < .001). CONCLUSION Labral repair leads to significant pain relief with cyst resolution within 2 to 3 months in most patients. Secondary muscle pathology (ie, edema, atrophy and fatty infiltration) may be partially or completely reversed. Bony erosion caused by cyst compression may be remodeled after cyst resolution.

Abstract
When a patient presents with shoulder pain and the workup reveals a spinoglenoid notch cyst, it is presumed by most to be related to an intra-articular SLAP tear. When managing this condition cyst excision has been advocated to alleviate suprascapular nerve pressure and also perhaps minimize recurrence assuming that the SLAP has also been treated. Cyst excision can endanger the suprascapular nerve and takes additional operating room time. The question is whether repairing the SLAP and therefore removing the starting point for the cyst would be adequate as the only surgical management. My preference is to leave the operating room with some indication that the pressure on the suprascapular nerve has been dealt with by at least decompressing the cyst. But on the basis of recent published experience, we may need to re-evaluate this.

Abstract
Background To examine the outcomes of combined biceps tenodesis and indirect, intra-articular arthroscopic paralabral cyst decompression for the treatment of active duty military patients with superior labral from anterior to posterior tears and associated paralabral cysts. Methods Retrospective chart review of all active duty patients at our institution from 2011 to 2014 with superior labral from anterior to posterior tears and associated paralabral cysts at the spinoglenoid notch treated with biceps tenodesis and indirect arthroscopic cyst decompression. Patient charts were examined for pre- and post-operative parameters including strength, range of motion, visual analog scale pain score, American Shoulder and Elbow Surgeon Score, and Single Assessment Numeric Evaluation Score. Results Seven patients met study criteria. All patients presented with chronic shoulder pain and decreased external rotation strength, and three patients had clinically apparent muscular atrophy. Pre- and post-operative assessment showed external rotation strength increased from a median of 4 (range 4-4) to 5 (range 4-5; p-value = 0.014), Single Assessment Numeric Evaluation increased from a median of 50 (range 0-70) to 75 (range 30-95; p-value = 0.031), American Shoulder and Elbow Surgeon increased from a median of 46.0 (range 32.0-58.0) to 66.5 (range 58.0-98.0; p-value = 0.068), and visual analog scale pain score decreased from a median of 3 (range 1-8) to 0 (range 0-5; p-value = 0.017). Median follow-up was 66 wk (range 36-138 wk). The change was statistically significant (p <0.05) for external rotation strength, Single Assessment Numeric Evaluation, and VAS reduction. Post-operatively, all patients returned to full duty at a median of 20 wk (range 12-36 wk). Conclusion The use of biceps tenodesis in conjunction with indirect, intra-articular arthroscopic paralabral cyst decompression is an effective technique in an active patient population with superior labral from anterior to posterior tear with associated paralabral cyst.

Arthroscopic management of suprascapular neuropathy of the shoulder improves pain and functional outcomes with minimal complication rates. Knee Surg Sports Traumatol Arthrosc 2018; 26:240-266. [PMID: 28879607 DOI: 10.1007/s00167-017-4694-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2017] [Accepted: 08/21/2017] [Indexed: 01/02/2023]
Abstract
PURPOSE The purpose of this study was to systematically assess the arthroscopic management of suprascapular neuropathy, including the aetiology, surgical decision-making, clinical outcomes, and complications associated with the procedure. METHODS Three databases [PubMed, Ovid (Medline), and Embase] were searched. Systematic literature screening and data abstraction was performed in duplicate to present a review of studies reporting on arthroscopic management of suprascapular neuropathy. The quality of the included studies was assessed using level of evidence and the MINORS (Methodological Index for Nonrandomized Studies) checklist. RESULTS In total, 40 studies (17 case reports, 20 case series, 2 retrospective comparative studies, and 1 prospective comparative study) were identified, including 259 patients (261 shoulders) treated arthroscopically for suprascapular neuropathy. The most common aetiology of suprascapular neuropathy was suprascapular nerve compression by a cyst at the spinoglenoid notch (42%), and the decision to pursue arthroscopic surgery was most commonly based on the results of clinical findings and investigations (47%). Overall, 97% of patients reported significant improvement in or complete resolution of their pre-operative symptoms (including pain, strength, and subjective function of the shoulder) over a mean follow-up period of 23.7 months. Further, there was a low overall complication rate (4%) associated with the arthroscopic procedures. CONCLUSION While most studies evaluating arthroscopic management of suprascapular neuropathy are uncontrolled studies with lower levels of evidence, results indicate that such management provides patients with significant improvements in pain, strength, and subjective function of the shoulder, and has a low incidence of complications. Patients managed arthroscopically for suprascapular neuropathy may expect significant improvements in pain, strength, and subjective function of the shoulder. LEVEL OF EVIDENCE Level IV, systematic review of level II to IV studies.

Abstract
Spinoglenoid cyst (SGC) is a ganglion arising in the spinoglenoid notch and is thought to be related to SLAP lesion. This cyst often compresses the suprascapular nerve in the spinoglenoid notch. Symptomatic cysts require surgical treatment when conservative treatment fails. In particular, arthroscopic decompression through the torn labral tissue when the cyst is extending into the joint cavity is easy and convenient. However, if the cyst is confined to the spinoglenoid notch, arthroscopic approach through the torn labral tissue is challenging. Thus, we present our preferred technique of addressing the SGC through an additional superior capsular window after completing SLAP repair. We believe that our technique is easy, reproducible, and reasonable.

Abstract
Background: Suprascapular nerve pathology is a rare diagnosis that is increasingly gaining popularity among the conditions that cause shoulder pain and dysfunction. The suprascapular nerve passes through several osseoligamentous structures and can be compressed in several locations. Methods: A thorough literature search was performed using online available databases in order to carefully define the pathophysiology and to guide diagnosis and treatment. Results: Suprascapular neuropathy diagnosis is based on a careful history and a thorough clinical and radiological examination. Although the incidence and prevalence of the condition remain unknown, it is highly diagnosed in specific groups (overhead athletes, patients with a massive rotator cuff tear) probably due to higher interest. The location and the etiology of the compression are those that define the treatment modality. Conclusion: Suprascapular neuropathy diagnosis is based on a careful history and a thorough clinical and radiological examination. The purpose of this article is to describe the anatomy of the suprascapular nerve, to define the pathophysiology of suprascapular neuropathy and to present methodically the current diagnostic and treatment strategies.

Abstract
PURPOSE To describe a spinoglenoid cyst decompression technique through a subacromial approach and its clinical outcomes after 2 years of follow-up. METHODS From March 2008 to October 2013, 26 patients underwent arthroscopic decompression of a spinoglenoid ganglion cyst with and/or without superior labral anterior to posterior repair, and patients who were available for minimum of 2 years of follow-up were included. For functional assessments, the visual analog scale (VAS) pain score, subjective shoulder value (SSV), University of California at Los Angeles (UCLA) shoulder score, American Shoulder and Elbow Surgeon (ASES) score, and shoulder active range of motion were used to compare preoperative and postoperative follow-up values. Follow-up magnetic resonance arthrography was taken at 6 months postoperatively to evaluate incomplete decompression or recurrence of the cyst. RESULTS In total, 21 patients were included in this study. At the 2-year follow-up, the VAS, SSV, ASES, and UCLA shoulder scores significantly improved compared with preoperative values (P < .001): VAS improved from 3.5 to 0.7 (P < .001); SSV improved from 62.9 to 93.1 (P < .001); ASES score improved from 64.3 to 94.4 (P < .001); UCLA shoulder score improved from 21.6 to 32.9 (P < .001). Also, active forward flexion improved from 153° to 158° (P = .014), and external rotation improved from 55° to 57° (P = .042) significantly, with the exception of internal rotation. The follow-up magnetic resonance arthrography was performed in 18 patients (86%), and there was no recurrence of the spinoglenoid notch cyst. CONCLUSIONS For spinoglenoid cyst decompression, the subacromial approach was found to be effective, yielding satisfactory clinical outcomes without recurrence.

Abstract
HYPOTHESIS The objective of this study was to improve our understanding of the pathogenesis and symptoms of ganglion cysts (GCs) in the spinoglenoid notch. Two hypotheses were tested: (1) the labral tears responsible for these cysts are mainly degenerative and nontraumatic, (2) spinoglenoid cysts are early magnetic resonance image (MRI) markers of eccentric posterior glenoid wear. MATERIALS AND METHODS This was a descriptive diagnostic study. Patients were included when a spinoglenoid cyst was discovered after complaints of pain in the posterosuperior aspect of the shoulder. MRI and arthroscopy were used to classify the glenoid GC and characterize the glenohumeral joint. The GCs were classified into 1 of 3 types: GC0 (isolated cyst), GC1 (cyst and associated labral lesion), and GC2 (cyst and associated labral and cartilage lesion). RESULTS Twenty patients (average age, 43 years) were included between 2000 and 2014. There were 7 GC0, 8 GC1, and 5 GC2 type cysts. Isolated labral tears (GC1) were always located posteriorly, without anterior extension or glenoid detachment. The humeral subluxation index was above 55% in 75% of shoulders, including all of the type GC2 shoulders. The 5 GC2 shoulders had type B1, B2, or C glenoids. CONCLUSIONS The management of paraglenoid labral cysts must go beyond addressing the suprascapular nerve compression related to traumatic labral detachment, and surgeons should look automatically for associated degenerative joint damage. The diagnosis of GCs should be supplemented by humeral subluxation index measurement on computed tomography scan or MRI, and the patient should be informed that joint-related posterior shoulder pain might persist in cases of GC1 and GC2.

Abstract
OBJECT High-resolution magnetic resonance imaging (MRI) can distinguish between intraneural ganglion cysts and paralabral (extraneural) cysts at the glenohumeral joint. Suprascapular intraneural ganglion cysts share the same pathomechanism as their paralabral counterparts, emanating from a tear in the glenoid labrum. The authors present 2 cases to demonstrate that the identification and arthroscopic repair of labral tears form the cornerstone of treatment for intraneural ganglion cysts of the suprascapular nerve. METHODS Two patients with suprascapular intraneural ganglion cysts were identified: 1 was recognized and treated prospectively, and the other, previously reported as a paralabral cyst, was identified retrospectively through the reinter-pretation of high-resolution MR images. RESULTS Both patients achieved full functional recovery and had complete radiological involution of the intraneural ganglion cysts at the 3-month and 12-month follow-ups, respectively. CONCLUSIONS Previous reports of suprascapular intraneural ganglion cysts described treatment by an open approach to decompress the cysts and resect the articular nerve branch to the glenohumeral joint. The 2 cases in this report demonstrate that intraneural ganglion cysts, similar to paralabral cysts, can be treated with arthroscopic repair of the glenoid labrum without resection of the articular branch. This approach minimizes surgical morbidity and directly addresses the primary etiology of intraneural and extraneural ganglion cysts.

Abstract
Suprascapular nerve injury is increasingly being recognized as an important cause of shoulder dysfunction. The non-specific clinical features of suprascapular nerve injury can make diagnosis difficult. However, it is essential for clinicians to consider it as part of the differential diagnoses in patients with vague pain or sensory disturbances over the posterosuperior part of their shoulder or have unexplained atrophy and weakness of their supraspinatus or infraspinatus muscle. Electrodiagnostic studies are useful in confirming and localising the nerve injury, while MRIs can be employed to determine the cause of nerve injury and assess the integrity of the rotator cuff muscles. Isolated suprascapular nerve injury can be managed with a trial of conservative management for at least 6 months. Subsequently, decompression of the nerve through open or arthroscopic techniques can be considered - both are associated with high rates of pain relief and functional improvement.

Abstract
Introduction: A spinoglenoid cyst with suprascapular nerve disorders is highly associated with superior labrum anterior posterior (SLAP) lesion. Conservative or surgical treatment is applied to relieve pain and neurological symptoms. The purpose of this study was to evaluate clinical outcomes of patients treated by arthroscopic surgery for SLAP lesion with a spinoglenoid cyst. Methods: The subjects of this study were six patients with SLAP lesion with a spinoglenoid cyst who underwent arthroscopic surgery. There was one female and five males with a mean age of 48.5 years. SLAP lesion was found in all the patients at arthroscopy. A small tear of the rotator cuff was found in the two patients. The SLAP lesion was repaired using suture anchors, and the rotator cuff tears were repaired by suture-bridge fixation. The spinoglenoid cyst was decompressed through the torn labrum in three patients, and through the released superior to posterior portion of the capsule in the other three patients. Results: All patients showed excellent improvement in pain and muscle strength at the final follow-up examination. The mean Constant score was improved from 60.5 points preoperatively to 97.2 points postoperatively. The mean visual analog scale (VAS) score decreased from 4.5 on the day of the surgery to 2.5 within one week postoperatively. Postoperative MRI showed disappearance or reduction of the spinoglenoid cyst in four and two patients, respectively. There were no complications from the surgical intervention and in the postoperative period. Discussion: The patients treated by decompression through the released capsule obtained pain relief at an early period after the surgery. Arthroscopic treatment for a spinoglenoid cyst can provide a satisfactory clinical outcome. Arthroscopic decompression of a spinoglenoid cyst through the released capsule is recommended for a safe and reliable procedure for patients with suprascapular nerve disorders.

Abstract
Surgical treatment of superior labral anterior posterior (SLAP) lesion becomes more and more frequent which is the consequence of evolving progress in both, imaging and surgical technique as well as implants. The first classification of SLAP lesions was described in 1990, a subdivision in four types existed. The rising comprehension of pathology and pathophysiology in SLAP lesions contributed to increase the types in SLAP classification to ten. Concerning the causative mechanism of SLAP lesions, acute trauma has to be differed from chronic degeneration. Overhead athletes tend to develop a glenohumeral internal rotation deficit which forms the basis for two controversial discussed potential mechanisms of pathophysiology in SLAP lesions: Internal impingement and peel-back mechanism. Clinical examination often remains unspecific whereas soft tissue imaging such as direct or indirect magnetic resonance arthrography has technically improved and is regarded to be indispensable in detection of SLAP lesions. Concomitant pathologies as Bankart lesions, rotator cuff tears or perilabral cysts should be taken into consideration when planning a personalized therapeutic strategy. In addition, normal variants such as sublabral recess, sublabral hole, Buford complex and other less common variants have to be distinguished. The most frequent SLAP type II needs a sophisticated approach when surgical teatment comes into consideration. While SLAP repair is considered to be the standard operative option, overhead athletes benefit from a biceps tenodesis because improved patient-reported satisfaction and higher rate of return to pre-injury level of sports has been reported.

Abstract
PURPOSE To analyze the clinical and radiologic outcomes of arthroscopic cyst decompression and labral repair in patients with inferior paralabral cysts with chronic shoulder pain. METHODS Between March 2006 and September 2012, 16 patients who were identified as having inferior paralabral cysts presented with chronic shoulder pain. All patients underwent a thorough physical examination and preoperative magnetic resonance arthrographic evaluation. The mean age was 30 years (range, 17 to 50 years). The mean follow-up period was 38 months (range, 16 to 60 months). Clinical outcome scores (American Shoulder and Elbow Surgeons; University of California, Los Angeles; and Simple Shoulder Test) and passive shoulder range of motion were evaluated at last follow-up. Follow-up magnetic resonance imaging was performed at a mean of 8 months to determine the labral healing status and assess for cyst recurrence. RESULTS The incidence of isolated inferior paralabral cysts was 0.6% (16 of 2,656 cases). Of the patients, 8 had multiple cysts and 8 had a single cyst. The mean length and width of the cysts were 1.0 cm and 0.4 cm, respectively. Eight cases had a history of trauma, and 13 patients were involved in sports activities. Seventy-five percent of cases showed a positive relocation test. The mean American Shoulder and Elbow Surgeons; University of California, Los Angeles; and Simple Shoulder Test scores improved from 64, 22, and 8.7, respectively, preoperatively to 83, 31, and 10, respectively (P < .001), at final follow-up. Shoulder range of motion did not show any significant improvement. The location of the labral tear was as follows: anteroinferior tear in 5 cases, posteroinferior tear in 8 cases, and combined anteroinferior and posteroinferior tear in 3 cases. All cysts were found to be in association with a labral tear. A mean of 2.7 anchors were used for inferior labral repair. These cysts were found only in male patients. None of the patients showed any evidence of cyst recurrence on follow-up magnetic resonance imaging. CONCLUSIONS Inferior labral tears treated with cyst decompression and labral repair showed satisfactory clinical results without any recurrence. Inferior paralabral cysts should be considered in the differential diagnosis in patients presenting with chronic shoulder pain, particularly active male patients. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
OBJECTIVE. In this article, we will review the normal anatomy and imaging features of various neuromuscular abnormalities related to suprascapular neuropathy. CONCLUSION. Suprascapular neuropathy can be difficult to distinguish from rotator cuff pathology, plexopathy, and radiculopathy. Electrodiagnostic studies are considered the reference standard for diagnosis; however, high-resolution 3-T MR neurography (MRN) can play an important role. MRN enables direct visualization of the nerve and simultaneous assessment of the cervical spine, brachial plexus, and rotator cuff.

Arthroscopic all-intra-articular decompression and labral repair of paralabral cyst in the shoulder. J Shoulder Elbow Surg 2015; 24:e7-e14. [PMID: 25174937 DOI: 10.1016/j.jse.2014.05.017] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2014] [Revised: 05/06/2014] [Accepted: 05/15/2014] [Indexed: 02/01/2023]
Abstract
BACKGROUND The purpose of this study was to report the outcomes of all-intra-articular arthroscopic decompression and labral repair in patients with symptomatic paralabral cysts. METHODS From 2005 to 2011, 20 consecutive cases of symptomatic paralabral cysts were included in this study. All surgical procedures were conducted with intra-articular arthroscopic decompression by use of a probe through the site of labral tear for cyst evacuation and suture anchor repair for the associated posterosuperior labrum. Clinical scores and magnetic resonance imaging (MRI) were obtained preoperatively and at follow-up. MRI was used to evaluate the size and segmentation of the cyst and the presence of the labral tear. RESULTS MRI revealed paralabral cysts in association with labral tears in all cases. Cysts were extended in the spinoglenoid notch with a mean size of 2.5 × 2.6 × 2.2 cm on MRI. Cysts were nonsegmented in 5 cases (25%) and had multiple segments in 15 cases (75%). Mean follow-up was 42.8 ± 21.22 months. The mean visual analog scale score for pain, the American Shoulder and Elbow Surgeons score, and the Simple Shoulder Test score significantly improved at the last follow-up (P < .001, P < .001, and P = .001, respectively). The postoperative MRI study performed at a mean of 6 months for 18 of 20 cases (90%) revealed complete cyst removal. The satisfaction level with surgery was good to excellent in 18 patients, fair in 1 patient, and poor in 1 patient. No complication was related to the surgical procedure. CONCLUSION Arthroscopic all-intra-articular decompression and labral repair of paralabral cyst can be a simple and effective treatment, regardless of segmentation or size. It also resulted in complete removal of the cyst at a mean of 6 months postoperatively as revealed by MRI. An additional subacromial procedure might not be necessary for complete decompression.

Abstract
PURPOSE Patients with spinoglenoid notch cyst associated with superior labrum anterior-to-posterior (SLAP) lesions were evaluated. The patients were all treated by arthroscopic cyst decompression combined with SLAP repair. The hypothesis of the study was that the patients who underwent prolonged conservative treatment period prior to surgery would exhibit significant infraspinatus hypotrophy and weakness, and their postoperative clinical and functional outcomes would be less satisfactory. METHODS Sixteen patients exhibited positive MRI and EMG findings with clinical signs of weakness and pain. The median age was 40.5 years (range 32-52), and the study group consisted of 11 males and 5 females with a median follow-up period of 26 months (12-48). The median duration of symptoms and conservative treatment prior to the surgical intervention was 3.5 months (1-14). Seven patients in group A exhibited infraspinatus hypotrophy. Group B comprised 9 patients without infraspinatus hypotrophy. RESULTS The results of the pre- and postoperative Constant scores, visual analogue scale (VAS) scores, and external rotation strength test rates were compared between groups. They all improved in terms of pain, strength, and function (P < 0.05). Significant differences were observed between the pre- and postoperative external rotation strengths and Constant scores (P < 0.05). However, no significant difference was observed between the pre- and postoperative VAS scores (n.s.). A significant correlation was observed in group A between surgical timing, the preoperative external rotation strength ratio (P = 0.04) and the postoperative VAS scores (P = 0.013). CONCLUSION The arthroscopic treatment was satisfactory with good clinical outcomes. Infraspinatus hypotrophy occurred in cases of prolonged surgical duration and significantly affected external rotation strength and functional outcomes.

Abstract
Studies have demonstrated favorable outcomes of arthroscopic decompression for ganglion cyst in the supraspinous fossa; however, little attention has been paid to the difficulty in detecting these cysts during arthroscopy. In this report, we present 2 cases in which ganglion cysts in the supraspinous fossa were undetectable during arthroscopy. The ganglion cysts were not identified in these cases during surgery despite arthroscopic decompression being performed through the area in which the cyst was expected until the suprascapular nerve was entirely exposed. After surgery, magnetic resonance imaging (MRI) confirmed the disappearance of the ganglion cyst and external rotation strength was fully improved, without shoulder pain. We emphasize here that surgeons should be aware of this difficulty when performing arthroscopic decompression of ganglion cysts in the supraspinous fossa.

Abstract
With increasing levels of competition at earlier ages, young athletes are becoming more susceptible to shoulder injuries. Overuse injuries in throwers are common conditions seen in pediatric and adolescent athletes. Little League shoulder and superior labial injuries are common due to the repetitive and high rotational forces placed on the shoulder during the throwing motion. Shoulder instability as a result of traumatic events occurring in collision sports is another frequent reason for young athletes to present to a sports medicine clinic. Although no operative treatment is often the first-line treatment for most of these injuries, shoulder surgery is becoming increasingly warranted in these young patients. Advanced cross-sectional imaging is important in guiding treatment for many of these injuries.

Abstract
BACKGROUND Some authors have described the ganglion cyst of the spinoglenoidal notch as related to repetitive overhead activities and labral tear caused by trauma, while others have explained lesions of the capsulolabral complex and ganglion cysts to have separate pathologies. The purpose of this study is to compare clinical and radiological outcomes between 2 groups: 1 with superior labrum anterior and posterior (SLAP) repair only and the other with SLAP repair and cyst decompression prospectively. MATERIALS AND METHODS From August 2000 to March 2007, 28 patients matching the inclusion criteria were selected for the study. They were divided into 2 groups: 1 who received SLAP repair and the other with concomitant SLAP repair and cyst decompression. A visual analogue scale (VAS) and Rowe and Constant scores were used to make evaluation. Preoperative magnetic resonance images (MRIs) of 2 patient groups were compared with 2 follow-up MRIs taken 3 months after the operation and at final follow-up. RESULTS Mean VAS and Constant and Rowe scores in groups I and II improved significantly from mean preoperative score compared to last follow-up score; however, there was no statistically significant difference between the 2 groups (P > .05). Preoperative MRI and arthroscopy revealed type II SLAP lesions and a type V lesion, respectively, as accompanying lesions in 24 cases. CONCLUSION The hypothesis stating 1-way valve mechanism of SLAP lesion as an initial cause of ganglion cysts has been proved indirectly in this study. Furthermore, direct decompression of the cyst does not lead to different results.

Abstract
Suprascapular nerve and rotator cuff function are intimately connected. The incidence of suprascapular neuropathy has been increasing due to improved understanding of the disease entity and detection methods. The nerve dysfunction often results from a traction injury or compression, and a common cause is increased tension on the nerve from retracted rotator cuff tears. Suprascapular neuropathy should be considered as a diagnosis if patients exhibit posterosuperior shoulder pain, atrophy or weakness of supraspinatus and infraspinatus without rotator cuff tear, or massive rotator cuff with retraction. Magnetic resonance imaging and electromyography studies are indicated to evaluate the rotator cuff and function of the nerve. Fluoroscopically guided injections to the suprascapular notch can also be considered as a diagnostic option. Nonoperative treatment of suprascapular neuropathy can be successful, but in the recent decade there is increasing evidence espousing the success of surgical treatment, in particular arthroscopic suprascapular nerve decompression. There is often reliable improvement in shoulder pain, but muscle atrophy recovery is less predictable. More clinical data are needed to determine the role of rotator cuff repair and nerve decompression in the same setting.

Abstract
Suprascapular neuropathy remains a rare, albeit increasingly recognized, diagnosis. Despite its relatively low prevalence, it must be kept in the shoulder surgeon's mind as a potential cause of shoulder pain, particularly in patients where the history, physical examination, and imaging studies do not adequately explain a patient's symptoms or disability. Although challenging to identify, suprascapular neuropathy can be successfully treated. The current literature shows that the location and mechanism of nerve injury are the most important factors guiding management. Different treatment strategies are required, depending on the specific location and type of nerve injury. Controversy regarding if and when to perform an isolated suprascapular nerve release continues. Furthermore, no recommendations regarding suprascapular nerve release in conjunction with rotator cuff repair can be made at this time, and further research is necessary to better delineate the indications in the future.

Abstract
INTRODUCTION Paralabral ganglion cysts of the shoulder are rare, and their pathogenesis is similar to that of meniscal cysts. The paralabral cysts are most frequently reported along the posterior, superior, and anterior aspects of the glenohumeral joint and are uncommon inferiorly to the joint. These cysts rarely become evident clinically, unless they cause compression of surrounding structures, i.e. nerve. PATIENTS AND METHODS We report a retrospective series of five patients with inferior paralabral ganglion cysts of the shoulder without compression of the surrounding nerve which were treated during the period from March 2007 to December 2009. All these patients presented with only chronic shoulder pain as their chief complaint, and preoperative MRI showed the cyst over the inferior aspect of a torn glenoid labrum. All patients were treated by arthroscopic cystic decompression with labrum repair. All patients were re-evaluated with MRI performed at an average of 15 months postoperatively. The clinical outcome, including the Constant score, was assessed for all patients at a median of 16 months postoperatively. RESULTS All the five patients had remission of pain and were satisfied with the shoulder function. The postoperative MRI in all patients showed no labral cyst recurrence. The median Constant score improved from a preoperative level of 81.5 points to 98.0 points at last follow-up. CONCLUSION This study demonstrates that, in the absence of any nerve compression symptoms around the shoulder joint, inferior paralabral cysts with labral tear also be considered in the differential diagnosis of chronic shoulder pain. Arthroscopic repair of the cyst with repair of the labrum can lead to the disappearance of symptoms. Knowledge of this clinical condition and its imaging features is critical for a correct diagnosis of this uncommon cause of chronic shoulder pain. LEVEL OF EVIDENCE Level IV.

Abstract
Although historically considered a diagnosis of exclusion, suprascapular neuropathy may be more common than once believed, as more recent reports are describing the condition as a cause of substantial pain and weakness in patients with and without concomitant shoulder pathology. The etiology is traction or compression of the suprascapular nerve. This can result from a space-occupying lesion, such as a ganglion cyst, or a traction injury as a result of repetitive overhead activities. More recent studies have cited cases of traction injuries occurring with retraction of a large rotator cuff tear. Atrophy of the infraspinatus and/or supraspinatus rotator cuff muscles with resultant weakness in forward flexion and/or external rotation of the shoulder on physical examination may be demonstrated. Magnetic resonance imaging (MRI) is the preferred modality to assess atrophy of the rotator cuff muscles as well as assess potential causes of suprascapular nerve compression. Electromyography and nerve conduction velocity studies remain the gold standard for confirmation of the diagnosis of suprascapular neuropathy; however, nerve pain may occur even in the setting of a negative electromyography. Initial management is usually nonoperative, consisting of activity modification, physical therapy, and nonsteroidal anti-inflammatory drugs. Surgical intervention is considered for patients with nerve compression by an external source or for symptoms refractory to conservative measures. Decompression of the suprascapular nerve may be accomplished through an open approach, although arthroscopic surgical approaches have become more common in the past several years.

Abstract
BACKGROUND Treatment of symptomatic spinoglenoid cysts has been controversial with options ranging from observation, to open excision, to arthroscopic decompression with or without labral repair. It has recently been suggested that isolated repair of SLAP lesions without cyst decompression can restore function in patients with spinoglenoid cysts and SLAP lesions. QUESTIONS/PURPOSES We examined gains in external rotation strength after isolated SLAP repair versus SLAP repair and cyst decompression to ascertain if gains in external rotation strength are attributable to SLAP repair or cyst decompression. METHODS We retrospectively reviewed external rotation strength of 12 patients: six with spinoglenoid cysts and Type II SLAP lesions who underwent arthroscopic SLAP repair and spinoglenoid cyst decompression and six with isolated SLAP lesions who underwent repair of the lesions. Preoperative and postoperative external rotation strength was evaluated using a digitally calibrated dynamometer on the operative and nonoperative sides. The minimum followup was 12 months (mean, 15.2 months; range, 12-27 months). RESULTS All of the patients in both cohorts had preoperative external rotation weakness on physical examination and dynamometer testing. The average increase in external rotation strength in the group of patients with SLAP lesions and paralabral cysts was 40% of the contralateral side versus 10% for the cohort with isolated SLAP repairs. CONCLUSIONS Decompression of paralabral cysts and SLAP repair in patients with preoperative external rotation weakness resulted in greater strength improvement than in patients with isolated SLAP repairs without complications of suprascapular neuropathy. This suggests that gains in external rotation strength are likely mostly attributable to cyst decompression, questioning isolated SLAP repair in the treatment of patients who have primarily weakness with spinoglenoid cysts.

Abstract
Suprascapular neuropathy has often been overlooked as a source of shoulder pain. The condition may be more common than once thought as it is being diagnosed more frequently. Etiologies for suprascapular neuropathy may include repetitive overhead activities, traction from a rotator cuff tear, and compression from a space-occupying lesion at the suprascapular or spinoglenoid notch. Magnetic resonance imaging is useful for visualizing space-occupying lesions, other pathological entities of the shoulder, and fatty infiltration of the rotator cuff. Electromyography and nerve conduction velocity studies remain the standard for diagnosis of suprascapular neuropathy; however, data on interobserver reliability are limited. Initial treatment of isolated suprascapular neuropathy is typically nonoperative, consisting of physical therapy, nonsteroidal anti-inflammatory drugs, and activity modification; however, open or arthroscopic operative intervention is warranted when there is extrinsic nerve compression or progressive pain and/or weakness. More clinical data are needed to determine if treatment of the primary offending etiology in cases of traction from a rotator cuff tear or compression from a cyst secondary to a labral tear is sufficient or whether concomitant decompression of the nerve is warranted for management of the neuropathy.

Abstract
Paralabral cyst of the shoulder joint can be observed in 2% to 4% of the general population, particularly in men during the third and fourth decade. On average, these cysts measure 10 mm to 20 mm in diameter and are located preferentially on the postero-superior aspect of the glenoid. The MRI has increased the frequency of the diagnosis of paralabral cysts of the shoulder joint. Paralabral cysts of the shoulder joint usually develop in the proximity of the labrum. The relationship between shoulder instability and labral tears is well known, however, the association of shoulder instability with a paralabral cyst is rare. Shoulder instability may cause labral injury or labral injury may cause shoulder instability, and then injured tear develops paralabral cyst. In our patient, the inferior paralabral cyst may be associated with inferior labral tears and instability MRI.

Abstract
Despite their rarity, several modalities have been used to treat spinoglenoid cysts of the shoulder. Recently, a report was issued on arthroscopic decompression through a communication hole and posterior capsulotomy through the glenohumeral joint. However, complete cystectomy is not possible using these methods if a cyst is large or extends anteriorly. Here, the authors describe a method of extra-articular complete cystectomy through the bursal space, which was used in three patients with large spinoglenoid cysts that extended anteriorly. All three patients were able to return to work without restriction, and in the two patients that underwent follow-up MRIs, cysts were completely resolved and the infraspinatus muscle mass had partially recovered.

Abstract
BACKGROUND Although entrapment of the suprascapular nerve (SSN) is an infrequent presentation of shoulder pain, proper diagnosis and treatment are critical to prevent chronic supraspinatus and infraspinatus atrophy. MATERIALS AND METHODS We present a technique that allows SSN decompression at the spinoglenoid notch or suprascapular notch through the subacromial space. RESULTS AND CONCLUSIONS This method allows for facile decompression of the SSN after repair of concomitant shoulder pathology and allows direct visualization of the medial neck of the glenoid to avoid complications of iatrogenic SSN nerve injury from aggressive medial capsule dissection. The purpose of this article is to provide surgeons with a safe, reliable method to decompress the SSN at the suprascapular or spinoglenoid notch.

Abstract
Lesions of the superior glenoid labrum and biceps anchor are a well-recognized cause of shoulder pain. Advances in shoulder arthroscopy have led to improvements in recognizing and managing superior labral anterior-posterior (SLAP) tears. Recent biomechanical studies have postulated several theories for the pathogenesis of SLAP tears in throwing athletes and the effect of these injuries on normal shoulder kinematics. Advances in soft-tissue imaging techniques have resulted in improved accuracy in diagnosing SLAP tears. However, the diagnosis of clinically relevant SLAP tears remains challenging because of the lack of specific examination findings and the frequency of concomitant shoulder injuries. Definitive diagnosis of suspected SLAP tears is confirmed on arthroscopic examination. Advances in surgical techniques have made it possible to achieve secure repair in selected patterns of injury. Recent outcomes studies have shown predictably good functional results and an acceptable rate of return to sport and/or work with arthroscopic treatment of SLAP tears.

Abstract
The shoulder joint has a wide breadth of derangements that can occur with sports activity. Whether the mechanism of injury is acute or the sequela of repetitive microtrauma, recent advances in musculoskeletal imaging and the understanding of athletic shoulder trauma will hopefully steer the clinician and radiologist alike to the proper diagnosis. Injury is inevitable. When it occurs, the clinician cognizant of the current concepts and protocols in the imaging of shoulder injury will be better prepared to diagnose and subsequently treat these disorders.

Abstract
Lesions of the superior labrum are complex and difficult to both diagnose and treat effectively. The clinical diagnosis is challenging due to the nonspecific history and physical examination. MRI has substantially improved our ability to detect SLAP tears, although experience is necessary to distinguish pathologic findings from normal anatomic variants. Treatment is determined by patient age, functional demands, and the type of lesion identified.

Arthroscopic decompression of the suprascapular nerve at the spinoglenoid notch and suprascapular notch through the subacromial space. Arthroscopy 2009; 25:439-45.

Abstract
Suprascapular nerve entrapment can cause disabling shoulder pain. Suprascapular nerve release is often performed for compression neuropathy and to release pressure on the nerve associated with arthroscopic labral repair. This report describes a novel all-arthroscopic technique for decompression of the suprascapular nerve at the suprascapular notch or spinoglenoid notch through a subacromial approach. Through the subacromial space, spinoglenoid notch cysts can be visualized between the supraspinatus and infraspinatus at the base of the scapular spine. While viewing the subacromial space through the lateral portal, the surgeon can use a shaver through the posterior portal to decompress a spinoglenoid notch cyst at the base of the scapular spine. To decompress the suprascapular nerve at the suprascapular notch, a shaver through the posterior portal removes the soft tissue on the acromion and distal clavicle to expose the coracoclavicular ligaments. The medial border of the conoid ligament is identified and followed to its coracoid attachment. The supraspinatus muscle is retracted with a blunt trocar placed through an accessory Neviaser portal. The transverse scapular ligament, which courses inferior to the suprascapular artery, is sectioned with arthroscopic scissors, and the suprascapular nerve is decompressed.
