Clinical outcomes of open Latarjet-Patte procedures performed for recurrent anterior shoulder instability with primary bone loss versus failed arthroscopic Bankart repair.

BACKGROUND: This study compares the outcomes of Latarjet-Patte procedures (LPs) performed for primary glenohumeral instability in the setting of critical bone loss (LP-BL) versus salvage surgery performed after a failed arthroscopic Bankart repair (LP-FB). METHODS: LP's performed by senior author from 2017 to 2021 were separated into cohorts by LP indication. Data abstracted from electronic medical records included demographic information, preoperative clinical scores, radiological imaging, and complications. Postoperative clinical outcome scores collected after a 2-year minimum follow-up included: patient-reported outcomes measurement information system (PROMIS) upper extremity (UE), PROMIS pain interference, PROMIS pain intensity, American Shoulder and Elbow Surgeons (ASES), and visual analog scale pain scores. RESULTS: A total of 47 patients (LP-BL: n=29, LP-FB: n=18) with a mean age of 29 years (range, 15-58 years) were included in this study. Both cohorts achieved good upper extremity functionality without significant differences as indicated by mean PROMIS UE (LP-BL: 52.6±10.0 vs. LP-FB: 54.6±7.6, P=0.442) and ASES score (LP-BL: 89.9±15.7 vs. LP-FB: 91.5±14.4, P=0.712). However, the LP-FB cohort reported lower levels of pain (LP-FB: 0.5±1.1 vs. LP-BL: 1.9±2.7, P=0.020) at their latest follow-up. There were no significant differences in complication rates including re-dislocation between cohorts (LP-BL: 2/29 [6.9%] vs. LP-FB: 2/18 [11.1%], P=0.629). CONCLUSIONS: When performed after failed Bankart repair, the LP results in similar postoperative functional outcomes and similar rates of complications and re-dislocations when compared to the primary indication of recurrent glenohumeral instability in the setting of critical bone loss. Level of evidence: III.

No difference in complications between two-week vs. six-week duration of sling immobilization after reverse total shoulder arthroplasty.

Background: The purpose of our study was to compare the outcomes and complications after a two- vs. six-week duration of sling immobilization following reverse total shoulder arthroplasty (rTSA). Methods: We conducted a retrospective review from our institutional database on 960 patients treated by primary rTSA between 2011 and 2021. Patients were separated into two cohorts of postoperative sling immobilization (a two-week and six-week group). Multivariate analysis was conducted to evaluate what factors were associated with patients experiencing either a postoperative complication or requiring reoperation. Results: A total of 276 patients were instructed to keep their operative arm in a sling for six weeks postoperatively, and 684 patients discontinued use at two weeks. There was no difference in postoperative complication rate (15.0% vs. 12.0%, P = .21), dislocation rate (P = .79), acromion stress fractures (P = .06), implant loosening (P = .15), and periprosthetic joint infections (P = .48) between the six- and two-week sling cohorts. In the immediate 90-day postoperative time period, no difference was seen in the reoperation rates (P = .73). Discussion: Shorter duration of sling immobilization (two weeks) does not incur additional risk of complications compared to standard duration (six weeks) of sling immobilization following rTSA.

Concomitant open distal clavicle excision is associated with greater improvement in range of motion without increased risk of acromial stress fracture after reverse total shoulder arthroplasty: a retrospective cohort study.

BACKGROUND: The purpose of this study was to evaluate the effect of concomitant open distal clavicle excision (DCE) on postoperative clinical outcomes and incidence of acromial and scapular stress fractures (ASFs) in patients with symptomatic acromioclavicular joint osteoarthritis (ACJ OA) undergoing reverse total shoulder arthroplasty (RTSA). METHODS: A single-surgeon retrospective cohort study was conducted including patients who underwent primary elective RTSA with or without DCE from 2015 to 2019 with a minimum 6-month follow-up period. Shoulder active range of motion (AROM) and visual analog scale (VAS) pain were recorded preoperatively and postoperatively. ASFs and other adverse events were identified using postoperative notes and/or radiographs. Characteristics and outcomes were compared between the RTSA and RTSA-DCE groups. RESULTS: Forty-six RTSA patients (mean age, 67.9±8.7 years; 60.9% male; mean follow-up, 24.9±16.6 months) and 70 RTSA-DCE patients (mean age, 70.2±8.9 years; 20.0% male; mean follow-up, 22.7±12.9 months) were included. There were no significant intergroup differences in rates of ASF (RTSA, 0.0% vs. RTSA-DCE, 1.4%; P=1.00), stress reactions (RTSA, 8.7% vs. RTSA-DCE, 11.4%; P=0.76), reoperation, revision, or infection (all P>0.05), or in pre-to-postoperative reduction in VAS pain (P=0.17) at latest follow-up. However, the RTSA-DCE group had greater pre-to-postoperative improvement in flexion AROM (RTSA, 43.7°±38.5° vs. RTSA-DCE, 59.5°±33.4°; P=0.03) and internal rotation (IR) AROM (P=0.02) at latest follow-up. CONCLUSIONS: Concomitant DCE in RTSA improves shoulder flexion and IR AROM, alleviates shoulder pain, and does not increase the risk of ASFs. Level of evidence: III.

Effects of increased body mass index on one year outcomes following soft tissue arthroscopic shoulder instability repair.

Background: The purpose of this study was to investigate the impact of high body mass index on the 1-year minimal outcome following arthroscopic shoulder stabilization. Methods: Patients who underwent arthroscopic Bankart repair (ABR) between 2017 and 2021 were identified and assigned to 1 of 3 cohorts based on their preoperative body mass index: normal (18-25), overweight (25-30), and obese (>30). The primary outcomes assessed were postoperative shoulder instability and revision rates. The 3 groups were compared using the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity, pain interference, pain intensity, Clinical Global Impression scores, visual analog scale pain scores, and shoulder range of motion at 1 year postoperatively. Results: During the study period, 142 patients underwent ABR and had an average age of 35 ± 10 years. Obese patients had a higher percentage of partial rotator cuff tears (60% vs. 27%, odds ratio: 3.2 [1.1, 9.2]; P = .009), longer mean operative time (99.8 ± 40.0 vs. 75.7 ± 28.5 minutes; P < .001), and shorter time to complication (0.5 ± 0 vs. 7.0 ± 0 months; P = .038). After controlling for confounding factors, obesity was associated with a lesser improvement in upper extremity function scores (obese vs. normal: -4.9 [-9.4, -0.5]; P = .029); although this difference exists, found future studies are needed to determine the clinical significance. There were no differences in patient reported outcome measures, recurrence rate, or revision surgery rates between cohorts at any time point (P > .05). Conclusion: Obesity is an independent risk factor for longer operative times but does not confer a higher risk of recurrent instability, revision surgery, or lower outcome scores 1 year following ABR.

Snapping Sternoclavicular Joint.

Snapping sternoclavicular joint (SCJ) is a rare presentation in the SCJ. We present a case report detailing the presentation and treatment of unilateral snapping SCJ in a 14-year-old male patient. Clinical findings included the subluxation of the medial end of the clavicle in the anterior-posterior direction following a specific maneuver by the patient that involved repetitive external rotation with the arm in horizontal abduction. Dynamic ultrasound demonstrated an asymmetric widening of the right sternoclavicular joint in the neutral position with a pronounced subluxation in provocative positioning. At 3.5-year follow-up, he continued to remain pain-free without static deformity of the SCJ. Snapping SCJ is a benign phenomenon that does not require any intervention and is not associated with ligament laxity.

Increased 90-Day Readmissions and Complications Following Hip Arthroscopy in Centers With Low Surgical Volume in New York State.

PURPOSE: To (1) classify surgical centers in New York State by volume of hip arthroscopies performed, (2) calculate rates of readmissions and complications by center volume, and (3) identify socioeconomic predictive factors for readmissions and complications following hip arthroscopy. METHODS: Patients who underwent hip arthroscopy at New York State health care facilities from 2010 to 2020 were retrospectively identified using the New York Statewide Planning and Research Cooperative System (SPARCS) database. Hip arthroscopic procedures were identified using the following Current Procedural Terminology codes. Surgical center volumes were classified into 3 categories: low (<85th percentile), medium (85th-95th percentile), and high (>95th percentile). Incidence of readmissions and complications within 90 days was abstracted from SPARCS. Neighborhood socioeconomic status was quantified using the U.S. Area Deprivation Index. Multivariable logistic regression was used to determine whether center volume and other socioeconomic variables were independent predictors of outcomes. RESULTS: In total, 50,252 patients who underwent hip arthroscopy were identified in SPARCS from 2010 to 2020. Of these patients, 13,861 (27.6%) underwent surgery at low-volume centers, 11,757 (23.4%) at medium-volume centers, and 24,634 (49.0%) at high-volume centers. Minorities, publicly insured patients, and patients from lower socioeconomic status neighborhoods made up a larger proportion of cases seen by low-volume centers versus high-volume centers (P < .001). Patients in the low-volume group experienced significantly greater 90-day rates of readmissions (P < .001) and all-cause complications (P < .001) than the other groups. Furthermore, high-volume centers were independently associated with lower odds of readmission (odds ratio 0.57, P < .001) and all-cause complications (odds ratio 0.73, P < .001) versus low-volume centers. CONCLUSIONS: Low-volume surgical centers are associated with increased readmission and complication rates following hip arthroscopy, independent of other socioeconomic factors such as age, sex, race, insurance status, and neighborhood socioeconomic status. LEVEL OF EVIDENCE: Level III, retrospective comparative prognostic trial.

Prognostic factors associated with improvements in patient-reported outcomes in idiopathic adhesive capsulitis.

Background: The purpose of this study was to identify prognostic factors that are associated with improvements in patient-reported outcomes measures (PROMs) related to upper extremity function and pain in those suffering from idiopathic adhesive capsulitis. Methods: All patients treated conservatively for primary idiopathic adhesive capsulitis were identified from our institutional database between 2019 and 2021. Exclusion criteria included any patients treated surgically, follow-up less than one year, or incomplete survey results. PROMs including Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test Version 2.0 (P-UE), Pain Interference (P-Interference), Pain Intensity (P-Intensity), and visual analog scale (VAS) pain scores. They were obtained at initial consultation and at one year to assess patient-perceived impact of their condition. Multiple linear and multivariable logistic regressions were performed to identify factors associated with improvement in patient-perceived pain and shoulder function using final PROM scores and difference in PROM scores from initial consultation. An independent t-test was used to compare baseline and one-year minimum follow-up PROMs. Odds ratios and their 95% confidence intervals were calculated for each factor; a P value of < .05 was considered statistically significant. Results: A total of 56 patients (40 females and 16 males) were enrolled in the study with an average age of 54.7 ± 7.7 years. A significant improvement (P < .001) was demonstrated at one-year minimum outcomes for P-UE, P-Interference, P-Intensity, and VAS scores. With respect to comorbid conditions, hypothyroidism [P-UE (ß: 9.57, P = .006)] was associated with greater improvements in PROMs, while hyperlipidemia [P-UE (ß: -4.13, P = .01) and P-Intensity (ß: 2.40, P = .02)] and anxiety [P-UE (ß: -4.13, P = .03)] were associated with poorer reported changes in PROMs. Female sex [P-UE (ß: 4.03, P = .007) and P-Interference (ß: -2.65, P = .04)] and employment in manual labor professions [P-Interference (ß: -3.07, P = .01), P-Intensity (ß: -2.92, P = .006), and VAS (ß: -0.66, P = .03)] were associated with significantly better patient-perceived outcomes. Hispanic heritage was associated with higher reported changes of P-Intensity (ß: 8.45, P = .004) and VAS (ß: 2.65, P = .002). Conclusion: Patient-perceived improvements in PROMIS score during the natural history of adhesive capsulitis are likely multifactorial, with anxiety, hyperlipidemia, increased body mass index, and Hispanic heritage associated with reduced improvement in PROMIS scores.

Return to Sport after Arthroscopic Rotator Cuff Repair of Full-Thickness Rotator Cuff Tears: A Systematic Review.

OBJECTIVE: Perform a systematic literature review regarding return to sport (RTS) outcomes after arthroscopic rotator cuff repair (aRCR) for full-thickness rotator cuff tears (FTRCTs). DATA SOURCES: Systematic review of all articles in PubMed, Medline, and Excerpta Medica Database (EMBASE) was conducted in April 2022 using a combination of keywords: "rotator cuff repair," "RCR," "complete," "full-thickness," "tear," "RCT," "injury," "shoulder," "arthroscopic," "return to sport," "RTS," "sport," "return to play," and "athlete." Cohorts were included from all articles reporting RTS after aRCR for FTRCTs. Studies that were non-English, failed to distinguish between partial and FTRCT outcomes, or treated FTRCTs by open RCR, mini-open RCR, debridement, or nonsurgical management were excluded. Abstracted data included study design, surgical techniques, concomitant procedures, demographics, FTRCT type and size, patient-reported outcomes, type of sport, competition level, time to return, and reasons for failing to RTS. MAIN RESULTS: 11 studies were reviewed, with inclusion of 463 patients (385 athletes; mean age 47.9). RTS varied considerably in rate and timing, with 50.0% to 100% of patients returning on average between 4.8 to 14 months. In addition, 31 patients returned to a higher level of sport, 107 returned to or near preinjury level, and 36 returned to a lower level of competition or failed to RTS entirely. CONCLUSIONS: The ability for athletes to RTS after aRCR for FTRCTs is likely multifactorial, demonstrating high variability in return rates and time to RTS. Given the paucity of available literature, future studies are warranted to provide a more definitive consensus.

Minimal clinically important difference (MCID) and substantial clinical benefit (SCB) of upper extremity PROMIS scores following arthroscopic rotator cuff repairs.

PURPOSE: To calculate and determine what factors are associated with achieving the Minimal Clinically Important Difference (MCID) and the Substantial Clinical Benefit (SCB) of Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Testing v2.0 (UE), Pain Interference (P-Interference), and Pain Intensity (P-Intensity) in patients undergoing arthroscopic rotator cuff repair (aRCR). METHODS: The change in PROMIS scores representing the optimal cutoff for a ROC curve with an area under the curve analysis was used to calculate the anchor-based MCID and SCB. To assess the responsiveness of each PROM, effect sizes and standardized response means (SRM) were calculated. To identify factors associated with attaining the MCID and SCB, univariate and multivariate logistic regression analyses were performed. RESULTS: A total of 323 patients with an average age of 59.9 ± 9.5 were enrolled in this study, of which, 187/323 [57.9%] were male and 136/323 [42.1%] were female. The anchor-based MCID for PROMIS UE, P-Interference, and P-Intensity was: 9.0, 7.5, and 11.2, respectively. The respective SCB was 10.9, 9.3, and 12.7. Effect size and SRM were: PROMIS UE (1.4, 1.3), P-Interference (1.8, 1.5), and P-Intensity (2.3, 2.0). Lower preoperative P-Intensity scores (p = 0.02), dominant arm involvement (p = 0.03), and concomitant biceps tenodesis (p = 0.03) were associated with patients achieving the SCB for PROMIS UE. CONCLUSION: A large responsiveness for each of the PROMIS instruments due to the majority of patients reporting great improvement after aRCR and a small standard deviation across all outcome measures was shown in our study. Lower preoperative P-Intensity scores and concomitant biceps tenodesis were associated with higher odds of achieving the SCB for PROMIS UE. The knowledge of MCID and SCB values for PROMIS instruments will allow the surgeon to determine whether the improvements in the PROMIS scores after aRCR are clinically meaningful. LEVEL OF EVIDENCE: Level III.

Minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) of upper extremity PROMIS scores in idiopathic adhesive capsulitis.

INTRODUCTION: The purpose of this study is to calculate the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) of Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Testing v2.0 (UE), Pain Interference (P-Interference), and Pain Intensity (P-Intensity) in patients treated nonoperatively for idiopathic adhesive capsulitis (IAC). METHODS: The anchor-based MCID, SCB, and PASS were calculated as the change in PROMIS scores representing the optimal cutoff for a ROC curve with an area under the curve (AUC) analysis. The distribution-based MCID was calculated as a range between the average standard error of measurement multiplied by two different constants: 1 and 2.77. Effect sizes and standardized response means (SRM) were calculated to assess the responsiveness of each PROMIS instrument while regression analyses were performed to identify factors associated with achieving these thresholds. RESULTS: This study enrolled 115 patients. The anchor-based MCID for PROMIS UE, P-Interference, and P-Intensity was 5.11, 4.16, and 8.16, respectively. The respective SCB was 8.44, 6.65, and 10.05. The respective PASS was 8.47, 7.01, and 10.41. The odds of achieving MCID values in adhesive capsulitis were negatively affected by gender (male), higher forward elevation at the time of presentation, higher pain scores (P-Interference), need for ≥ 2 corticosteroid injections, and a concomitant diagnosis of diabetes. CONCLUSION: The MCID, SCB, and PASS parameters for PROMIS scores can be utilized to determine the clinical meaningfulness of patient-reported improvements in these instruments during the nonoperative treatment and as a research tool to compare the efficacy of new treatments for adhesive capsulitis. LEVEL OF EVIDENCE: Level III, basic science study, validation of outcome instruments. Key points • This is the first study to calculate the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) for the Patient-Reported Outcome Measurement Information System (PROMIS) Upper Extremity and Pain instruments in patients with idiopathic adhesive capsulitis (IAC) of the shoulder.• This study determined the impact of symptom severity, demographics, and comorbidities on achieving the MCID, SCB, and PASS for PROMIS instruments in IAC patients treated nonoperatively.

Comparison of 90-day complication rates and readmissions of primary total elbow arthroplasty in elective and traumatic cases: a single center experience.

INTRODUCTION: The purpose of this study is to compare the 90 day complication rates of primary Total Elbow Arthroplasty (TEA) performed for arthritis (primary-OA; rheumatoid arthritis-RA) versus those performed for distal humerus fractures (DHF). METHODS: Patients who underwent a TEA from 2015 to 2021 were identified from our institutional database and placed into cohorts based on surgical indications (TEA-OA, TEA-RA and TEA-DHF). Chart review was conducted to analyze the prevalence of complications, emergency department (ED) visits, readmissions, and secondary procedures in the first 90 day post-operative period. Complications included but were not limited to wound complications, hematoma, infection (superficial or deep), nerve palsy, periprosthetic fracture/failure and others. RESULTS: 49 patients who underwent TEA were included in this study: (DHF = 19, OA = 14, RA = 16). Six complications occurred within the first 90 days of surgery. There were two periprosthetic joint infections (PJI) in the OA group, requiring irrigation and debridement (I & D) within the first 90 days of surgery. There were three post-operative ulnar nerve palsies and one PJI requiring I & D in the TEA-RA group. Compared to the TEA-DHF and TEA-OA groups, the RA group had higher rates of all-cause complications (p = 0.03) and nerve palsy (p = 0.03). There were no significant differences between groups in readmissions (p = 0.27) or secondary interventions (p = 0.27). CONCLUSION: The 90-day complication/readmission rates of TEA preformed for DHFs is lower than those preformed for OA and RA. These differences could be related to the underlying chronic inflammatory etiology and side effect of treatments (intraarticular steroid injection, and biologics) received by patients with arthritis. LEVEL OF EVIDENCE: Retrospective Cohort Study, level IV.

Short-term outcomes of instability related anterior glenoid fractures treated with open repair utilizing subscapularis split technique.

INTRODUCTION: The purpose of this series is to report on the one-year clinical outcomes of instability related anterior glenoid fractures treated with open repair utilizing the subscapularis split technique. METHODS: Patients with displaced anterior glenoid fractures who underwent open surgical treatment via deltopectoral incision and subscapularis split were identified from a single surgeons database. Fractures were repaired using screw fixation or with distal tibia osteochondral allograft reconstruction. Patient Reported Outcome Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE), PROMIS Pain interference (PI), PROMIS pain intensity (Pi), American Shoulder and Elbow Surgeons (ASES), Visual Analog Scale (VAS) pain, and Subjective Shoulder Value (SSV) scores were obtained at minimum one-year follow-up. RESULTS: Twelve patients with a mean age of 54 (range 28-72) years were included in our study with a follow-up at an average of 16.6 (range 12-30) months. Ten patients underwent internal fixation and two patients underwent allograft reconstruction. Postoperative imaging (n = 10) at latest follow-up demonstrated healed fractures without any hardware complication. Mean postoperative range of motion included forward elevation of 147 ± 44.0° and external rotation of 44 ± 17°. Postoperative PROMs were obtained from nine patients with a mean PROMIS UE, PI, and Pi score of 49.4 ± 4.1, 39.9 ± 3.8 and 35.6 ± 4.3, respectively. The respective mean ASES, VAS, and SSV scores were 91.8 ± 7.2, 1.2 ± 1.0, and 91.0 ± 8.0. CONCLUSION: Open surgical repair of anterior glenoid fractures utilizing subscapularis split results in good functional outcomes and low complications including risk of recurrent instability. LEVEL OF EVIDENCE: III case series.

Cheilectomy With Decompression Osteotomy for Treatment of Hallux Limitus and Rigidus: A Retrospective Study With 5-Year Outcomes.

We examined outcomes following metatarsophalangeal joint cheilectomy with decompression osteotomy to evaluate the efficacy of this technique for treatment of hallux limitus/rigidus. At a minimum follow-up of 5 years, we identified 94 patients who fit the inclusion criteria. Chart review was performed to obtain range of motion (ROM) of the first metatarsophalangeal joint (MTPJ) preoperatively and at 6 weeks, 6 months, and 5 years postoperatively. Additionally, time to traditional shoe gear return, need for revision arthrodesis, radiographic findings, and postoperative visual analog scale (VAS) pain scores were reviewed. Statistical analysis was conducted by 1-way analysis of variance with post-hoc analysis and independent sample t-test. At an average follow-up of 6.3 ± 0.9 years, 42.3% (33/78) of females and 25.0% (4/16) of males reported limited ROM of the first MTPJ with 5 patients requiring first MTPJ arthrodesis. MTPJ ROM improved on average from 11.0° to 36.3° by 5-year minimum follow-up after surgery (p < .001). Analysis of variance revealed a significant difference of the preoperative ROM when compared to all postoperative time points (F[3,368] = 69.4, p < .001). Mean postoperative VAS pain scores after decompression osteotomy of the 5 patients who required MTPJ fusion were higher when compared to the rest of the patient cohort at final follow-up (7.4 ± 0.6 vs 1.5 ± 1.3; p < .001). Cheilectomy with decompression osteotomy for treatment of hallux limitus/rigidus leads to satisfactory long-term outcomes.

Outcomes after arthroscopic scapulothoracic bursectomy for the treatment of symptomatic snapping scapula syndrome.

Background: The purpose of our study was to examine the clinical outcomes after arthroscopic scapulothoracic bursectomy for the treatment of scapulothoracic bursitis at a minimum of 2-year follow-up. Methods: Twenty patients who underwent arthroscopic scapulothoracic bursectomy for the treatment of symptomatic snapping scapula syndrome were identified from a single surgeon's database. Patients were indicated for surgery if their symptoms persisted for more than 6 months and if they failed nonoperative treatment. Acquired data included patient demographics, shoulder range of motion, American Shoulder and Elbow Surgeon score, visual analog scale scores for pain, and the following Patient-Reported Outcomes Measurement Information System scores: Upper Extremity Computer Adaptive Test Version 2.0, pain intensity, and pain interference scores. Patient satisfaction and subjective shoulder value were also recorded out of 100. Fisher's test and unpaired t tests were performed for statistical analysis, and P values <.05 were considered significant. Results: A total of 20 patients (24 scapulae) were included in our study, with an average follow-up period of 44 (range: 27-91) months. The mean postoperative Patient-Reported Outcomes Measurement Information System scores for Upper Extremity Computer Adaptive Test Version 2.0, pain interference, and pain intensity were 44.2 ± 10.7, 50.9 ± 9.5, and 42.1 ± 9.5, respectively. The mean postoperative American Shoulder and Elbow Surgeon score was 79.0 ± 21.5, and the mean subjective shoulder value was 82.7 ± 12.9. Visual analog scale pain levels showed a significant decrease from 4.95 ± 2.26 preoperatively to 2.27 ± 2.7 (P < .05) postoperatively. There was no significant difference in shoulder range of motion after surgery. The mean patient satisfaction was 72.9, with 65% (13/20) of patients reporting satisfaction levels ≥ 80%. Two patients did not report the resolution of their symptoms and required revision surgery. Conclusion: Arthroscopic treatment of scapulothoracic bursitis is a safe, reliable technique that is effective in providing symptomatic relief with a low rate of recurrence, with most patients reporting a significant reduction in periscapular pain.

No Differences in 90-Day Complications and Admissions After Latarjet Procedure for Primary Bone Loss Versus Latarjet Procedure for Failed Arthroscopic Instability Repair.

Purpose: To investigate the variance in 90-day complication, emergency department (ED) visit, revision, and readmission rates between the Latarjet procedure (LP) performed as a primary procedure for the treatment of recurrent shoulder instability associated with critical levels of glenohumeral bone loss and the LP performed as a salvage surgical procedure after failed arthroscopic instability repair (FAIR). Methods: Patients who underwent a primary LP from 2016-2021 in a single surgeon's practice were identified and divided into 2 cohorts based on the indication for surgery: primary LP for critical bone loss (unipolar or bipolar) (LP-PBL) or LP as salvage surgery for FAIR (LP-FAIR). Patients without a minimum follow-up period of 90 days were excluded. Chart review was conducted to analyze the prevalence of complications, ED visits and/or admissions, and secondary procedures in the 90-day postoperative period. Radiographic images were reviewed to evaluate for graft and/or hardware failure. An unpaired t test and the Fisher exact test were used to compare the 2 groups regarding continuous and categorical data, respectively, and the significance level was set at P < .05. Results: The final sample sizes consisted of 54 patients in the LP-PBL group and 23 patients in the LP-FAIR group. In the postoperative period, 4 complications were observed in the first 90 days. These included complex regional pain syndrome (n = 1) and superficial wound dehiscence (n = 1) in the LP-PBL cohort. Superficial suture abscess (n = 1) and audible crepitation (n = 1) were observed in the LP-FAIR cohort. There was 1 secondary intervention (arthroscopic debridement) in the LP-FAIR cohort. No statistically significant difference in complication rates, ED visits or admissions, or secondary procedures was found between the LP-PBL and LP-FAIR groups. Conclusions: The results of this study indicate that the 90-day complication, ED visit, revision, and readmission rates after open LP are low irrespective of the extent of glenoid or bipolar bone loss and history of arthroscopic instability repair. Level of Evidence: Level III, retrospective cohort study.

Isolated infraspinatus musculotendinous junction tear treated with open repair and dermal allograft augmentation: a case report with 5-year outcome.

We report the 5-year outcome of an isolated, atraumatic full-thickness infraspinatus myotendinous junction tear treated with open surgical repair. The index patient developed severe pain and weakness in external rotation strength following a subacromial corticosteroid injection. Magnetic resonance imaging and ultrasound of the shoulder demonstrated a full-thickness myotendinous junction tear with extensive muscle edema, mild atrophy and a spinoglenoid notch varix. Due to persistent, worsening pain and presence of ER weakness, the patient underwent primary infraspinatus muscle-tendon repair with allograft augmentation via an arthroscopic-assisted open posterior approach. The patient had an uneventful postoperative course with a resolution of pain and improvement in ER strength, which is maintained at the latest 5-year follow-up. This case report highlights a favorable long-term outcome of an isolated infraspinatus myotendinous junction tear treated with primary muscle-tendon repair and dermal allograft augmentation.

The effects of obesity on 1-year functional outcomes after arthroscopic rotator cuff tear repair.

Background: The purpose of our study was to examine the impact that an increased body mass index (BMI) has on arthroscopic rotator cuff repair (aRCR) outcomes. Methods: We identified a sample of 313 patients who underwent aRCR at our institution from 2017 to 2020. Patients were classified into cohorts by BMI: normal BMI (<25), overweight (25-30), and obese (≥30). Patient-Reported Outcomes Measurement Information System (PROMIS) scores (Pain Interference, Pain Intensity, and Upper Extremity) and Clinical Global Impressions scale rating of pain and functional improvement after surgery were obtained at 1 year postoperatively. The significance of the BMI category as a predictor for outcomes was evaluated using multiple linear and multivariable logistic regressions. Receiver operating characteristic curve analysis with Youden's J-statistic was used to determine optimal BMI cutoff for predicting likelihood of achieving minimum clinically important difference (MCID) and substantial clinical benefit (SCB) on the Clinical Global Impressions scales. Results: Obesity was a significant predictor of reduced preoperative-to-postoperative improvement in the PROMIS Upper Extremity score (P = .04). However, BMI was not predictive of other preoperative-to-postoperative differences in outcome scores or the size and number of cuff tendons torn (P > .05). Optimal BMI cutoffs were determined for pain MCID (40.8), pain SCB (26.8), function MCID (27.4), and function SCB (26.8), but all cutoffs had low correct classification rates (≤13%). Discussion and Conclusion: Obesity was not found to be an independent risk factor for increased rotator cuff tear size or tendon involvement but was nonetheless associated with worse upper extremity function and pain after aRCR.

Inlay versus onlay humeral design for reverse shoulder arthroplasty: a systematic review and meta-analysis.

BACKGROUND: Since the introduction of the Grammont-style reverse total shoulder arthroplasty, the humeral stem design has been modified with improved clinical outcomes. Two distinct humeral designs have been used extensively: the inlay design, in which the humeral tray is seated within the metaphysis, and the onlay design, in which the humeral tray sits on the metaphysis at the level of the humeral neck cut. The purpose of this systematic review was to determine whether there are differences in clinical outcomes and complication rates between these designs. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were used to perform this systematic review. A search of MEDLINE, PubMed, and Embase was performed to identify all studies comparing the clinical results of both humeral designs. Primary outcomes included patient-reported outcome measures, shoulder range of motion, and incidence of complications. RESULTS: From the 156 identified publications, 12 studies were included in the final review. A total of 1447 patients were included, with a minimum follow-up period of 12 months. At final follow-up, both implants demonstrated significant improvements in comparison to preoperative baseline. On comparison of the inlay vs. onlay groups, the American Shoulder and Elbow Surgeons score was higher in the inlay group (mean difference, 2.53 [95% confidence interval, 0.27-4.78]; P = .03). Postoperative motion, even if statistically greater in the onlay group (differences of 5° in forward flexion [P < .001], 3° in abduction [P = .003], and 4° in external rotation [P < .001]), was not clinically different. On comparison of complications, the inlay group showed more instances of scapular notching (93 of 322 patients vs. 70 of 415 patients; odds ratio, 0.35; P < .001) but fewer scapular spine fractures (26 of 727 patients vs. 21 of 559 patients, P = .09). DISCUSSION: Inlay and onlay humeral tray designs in reverse total shoulder arthroplasty demonstrate similar clinical improvements postoperatively. Onlay implants have a low rate of scapular notching but a higher rate of scapular spine fracture. Understanding the strengths and weaknesses of the 2 humeral tray designs is important to provide surgeons with options to tailor surgical plans for high-risk patients.

Wound Complication and Neuropraxia of the Posterior Cutaneous Nerve of the Arm after Primary Repair of a Latissimus Dorsi and Teres Major Tear.

We present a case of a surgically treated latissimus dorsi (LD) and teres major (TM) tear with a one-year outcome. The postoperative course was complicated by wound dehiscence requiring operative intervention and neuropraxia of the posterior cutaneous nerve of the arm. The report highlights previously unreported surgical risks associated with repair of LD/TM tendons.

Atraumatic Deltoid Rupture with a Chronic Massive Rotator Cuff Tear: A Case Report and Surgical Technique.

Case: We report a rare case of a spontaneous, atraumatic rupture of the anterior and middle heads of the deltoid with an underlying massive rotator cuff tear. Unique clinical findings included a palpable mass of torn deltoid distally with a proximal tissue defect. Magnetic resonance imaging of the deltoid demonstrated complete tear of the anterior head; involvement of the middle head was found intraoperatively. Given the acute nature of injury and potential impact on the feasibility of future reverse shoulder arthroplasty, surgical repair of the torn deltoid was discussed with the patient and performed via superior approach. Conclusion: Direct surgical repair is a viable treatment option if diagnosed early.
