Thumb-Sparing Surgery for Digital Papillary Adenocarcinoma: A Case Report.

Digital papillary adenocarcinoma (DPA) is a rare eccrine sweat gland tumor that often appears as a solitary, non-painful, gradually enlarging mass. Clinically, DPA presents considerable challenges due to its high likelihood of recurrence and its tendency to spread to the lymph nodes and lungs. This case report focuses on the surgical treatment of a unique case of DPA located on the dorsal thumb in a 46-year-old male. The patient initially underwent wide local excision with temporary wound coverage, and once final histopathological findings confirmed negative margins, a second procedure consisting of thumb interphalangeal joint fusion and first dorsal metacarpal artery flap coverage was performed. Eighteen months later, the patient continued to work in landscaping, performing the physically demanding tasks required by the job. This case demonstrates the feasibility of thumb preservation in the setting of soft tissue malignancy once negative margins are obtained.

Effectiveness of Arthroscopic Debridement, Trapeziectomy, and Joint Replacement for Trapeziometacarpal Joint Osteoarthritis: A Meta-Analysis of Pre and Postoperative Pain Scores.

Trapeziometacarpal joint osteoarthritis (TMJO) affects up to 33% of postmenopausal women, leading to pain, reduced mobility, and grip strength, with initial treatments focusing on non-surgical options like injections, orthoses, and exercises before considering surgery. A major challenge in managing TMJO involves selecting the optimal surgical strategy that is customized to individual clinical conditions. This study aimed to compare the effectiveness of three common surgical interventions for TMJO in relieving pain, including arthroscopic debridement (AD), trapeziectomy (TRAP), and joint replacement (JR). PubMed, Cochrane, Embase, and MEDLINE databases were queried according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for studies that presented pain outcomes following intervention for TMJO. Pain scores were reported preoperatively and postoperatively using the visual analog scale (VAS). Inclusion criteria included studies published in Q1 and Q2 journals and those with a follow-up of > six months. The final selection comprised 18 studies with 763 patients treated with AD (n = 102, 13%), TRAP (n = 428, 56%), and JR (n = 233, 31%) between 2010 and 2023, with a mean follow-up period of 38 ± 28 months. The studies included a total of 24 groups, five of which received AD, 13 of which received TRAP, and six of which received JR. The mean preoperative VAS was 6.7 ± 1.7, and the mean postoperative VAS was 1.7 ± 1.3 for all groups (P < 0.001). The meta-analysis demonstrated a mean preoperative pain score of 5.8 (95% CI, 4.1-7.5) for AD, 6.6 (95% CI, 5.7-7.5) for TRAP, and 7.8 (95% CI, 7.0-8.7) for JR. Postoperatively, there was a mean pain score of 2.2 (95% CI, 0.1-4.2) for AD, 1.4 (95% CI, 1.1-1.7) for TRAP, and 0.9 (95% CI, 0.6-1.2) for JR. This study showed that, if appropriately indicated, joint preservation with AD may be as effective as TRAP and JR for reducing pain associated with TMJO in the short term. However, the rate of conversion or revision should be assessed in future studies.

Quantifying Threshold Scores for Patient Satisfaction After Massive Rotator Cuff Repair for the Interpretation of Mid-Term Patient-Reported Outcomes.

PURPOSE: To establish minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) values for 4 patient-reported outcomes (PROs) in patients undergoing arthroscopic massive rotator cuff repair (aMRCR): American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), Veterans Rand-12 (VR-12) score, and the visual analog scale (VAS) pain. In addition, our study seeks to determine preoperative factors associated with achieving clinically significant improvement as defined by the MCID and PASS. METHODS: A retrospective review at 2 institutions was performed to identify patients undergoing aMRCR with minimum 4-year follow-up. Data collected at the 1-year, 2-year, and 4-year time points included patient characteristics (age, sex, length of follow-up, tobacco use, and workers' compensation status), radiologic parameters (Goutallier fatty infiltration and modified Collin tear pattern), and 4 PRO measures (collected preoperatively and postoperatively): ASES score, SSV, VR-12 score, and VAS pain. The MCID and PASS for each outcome measure were calculated using the distribution-based method and receiver operating characteristic curve analysis, respectively. Pearson and Spearman coefficient analyses were used to determine correlations between preoperative variables and MCID or PASS thresholds. RESULTS: A total of 101 patients with a mean follow-up of 64 months were included in the study. The MCID and PASS values at the 4-year follow-up for ASES were 14.5 and 69.4, respectively; for SSV, 13.7 and 81.5; for VR-12, 6.6 and 40.3; and for VAS pain, 1.3 and 1.2. Greater infraspinatus fatty infiltration was associated with failing to reach clinically significant values. CONCLUSIONS: This study defined MCID and PASS values for commonly used outcome measures in patients undergoing aMRCR at the 1-year, 2-year, and 4-year follow-up. At mid-term follow-up, greater preoperative rotator cuff disease severity was associated with failure to achieve clinically significant outcomes. LEVEL OF EVIDENCE: Level IV, case series.

Both Radiologists and Surgeons Miss a Substantial Number of Subscapularis Tears on Magnetic Resonance Imaging Examination Prior to Shoulder Arthroscopy.

Purpose: To compare radiologist and surgeon magnetic resonance imaging (MRI) interpretations of subscapularis (SSC) tears against intraoperative arthroscopic examination. Methods: We conducted a retrospective review of prospectively maintained data on patients who underwent arthroscopic rotator cuff repair with and without SSC tears between 2011 and 2022. The radiologists' assessments of SSC integrity were extracted from the MRI reports. One high-volume fellowship-trained shoulder surgeon assessed all MRI scans for the presence or absence of SSC tears. Radiologist and surgeon MRI-based assessments were compared against the diagnostic gold standard (intraoperative arthroscopic examination) and classified according to the Lafosse classification. Sensitivity, specificity, positive and negative predictive values, and accuracy were calculated. Results: A total of 1,090 patients were included for analysis, 839 with intraoperatively confirmed SSC tears (77%) and 251 without such tears (23%). Radiologists diagnosed SSC tears with a sensitivity of 56.0% (470 of 839 patients) and specificity of 67.3% (169 of 251 patients) via MRI, whereas the surgeon diagnosed SSC tears with a sensitivity of 71.4% (599 of 839 patients) and specificity of 78.1% (196 of 251 patients). Overall, radiologists only correctly identified 56% of SSC tears whereas the shoulder surgeon correctly identified approximately 71.4% of tears. When considering arthroscopically confirmed tear size, that is, intact, partial, full thickness [upper border], and complete, the radiologists' diagnosis rates with MRI were 67.3%, 40.4%, 64.6%, and 78.3%, respectively, and the surgeon's diagnosis rates were 78.1%, 52.7%, 81.9%, and 97.5%, respectively. Conclusions: In a community practice, radiologists miss approximately 50% of SSC tears on MRI examination. A shoulder surgeon with the benefit of clinical examination misses 28.6% of tears on MRI. Accuracy increases as tear size increases, with radiologists detecting 40.4% of partial tears and 78.3% of complete tears and a surgeon detecting 52.7% and 97.5%, respectively. Level of Evidence: Level III, diagnostic study (nonconsecutive patients).

Missed Diagnosis of a Rare Retropatellar Juxta-Articular Angioleiomyoma: A Case Report.

Angioleiomyomas are benign tumors that originate from smooth muscle cells and most commonly affect organs such as the uterus or gastrointestinal tract. This article presents a case of a rarely reported angioleiomyoma located in the retropatellar juxta-articular region of the knee. The patient is a 42-year-old female who experienced chronic anterior knee pain that led to two unsuccessful arthroscopic surgeries. Magnetic resonance imaging (MRI) revealed a well-defined lesion in the retropatellar area, prompting the decision to proceed with open surgery. The histopathological examination confirmed the diagnosis of angioleiomyoma. This case highlights the challenges in diagnosing angioleiomyomas in the knee and emphasizes the importance of comprehensive MRI evaluation for accurate diagnosis and appropriate surgical intervention. Prompt identification and excision of the soft tissue lesion can lead to the complete resolution of symptoms and effective management of this rare condition.

Remote visual estimation of shoulder range of motion has generally high interobserver reliability but limited accuracy.

Background: Surgeon visual estimation of shoulder range of motion (ROM) is commonplace in the outpatient office setting and routinely reported in clinical research, but the reliability and accuracy of this practice remain unclear. The purpose of this study is to establish the reliability and accuracy of remote visual estimation of shoulder ROM in healthy volunteers and symptomatic patients among a large group of shoulder surgeons. Our hypothesis is that remote visual estimation would be reliable and accurate compared with the digital goniometer method. Methods: Fifty shoulder surgeon members of the PacWest Shoulder and Elbow Society independently determined the active shoulder forward flexion (FF), internal rotation at 90° abduction (IR90), external rotation at 90° abduction, external rotation at the side , and maximal spinal level reached with internal rotation (IRspine) through visual estimation of video recordings taken from 10 healthy volunteers and 10 symptomatic patients. Variations in measurements were quantified using the interobserver reliability through calculation of the intraclass correlation coefficient. Accuracy was determined through comparison with digital goniometer measurements obtained with an on-screen protractor application using Bland-Altman mean differences and 95% limits of agreement. Results: The interobserver reliability among examiners showed moderate to excellent correlation, with intraclass correlation coefficient ranging from 0.768 to 0.928 for the healthy volunteers and 0.739 to 0.878 for the symptomatic patients. Accuracy was limited, with upper limits of agreement exceeding the established minimal clinically important differences (MCIDs) for FF (20° vs. MCID of 14°) and IR90 (25° vs. 18°) in the healthy volunteers and for FF (33° vs. 16°), external rotation at 90° abduction (21° vs. 18°), and IR90 (31° vs. 20°) in the symptomatic patients. Conclusion: Despite generally high intersurgeon reliability in the visual estimation of shoulder ROM, there was questionable accuracy when compared to digital goniometer measurements,with measurement errors often exceeding established MCID values. Given the potential implications for the clinical response to treatment and the significance of research findings, the adoption of validated instruments to measure ROM and the standardization of examination procedures should be considered.

Arthroscopic Capsular Release for Post-traumatic Elbow Stiffness.

BACKGROUND: Post-traumatic elbow stiffness (PTES) may substantially affect the patient's functional range of motion and quality of life. Open elbow release has been extensively studied, but arthroscopic techniques are limited, particularly in differentiating between post-traumatic and non-traumatic stiffness. The purpose of this study is to assess the clinical outcomes after arthroscopic release of PTES regarding the range of motion (ROM), pain, functional assessment, and complications. METHODS: A prospective cohort was conducted on adult patients who underwent arthroscopic arthrolysis for PTES, with 32 patients included in the final analysis. The ROM was measured using the orthopedic goniometer. Grip strength was measured using the Camry digital hand dynamometer (Camry, CA, USA) and compared to their contralateral side. The functional status of the patients was evaluated using the American Shoulder and Elbow Surgeons Score (ASES)andthe Mayo Elbow Performance Index (MEPI). All measurements were done before surgery and at the last follow-up visit. Pre-operative and post-operative changes in MEPI, ASES, and visual analog (VAS) scores were compared with the paired t-test. RESULTS: After surgery, the ROM significantly improved from 74 ± 11 to 110 ± 15 degrees (p<0.001). Additionally, the ASES score and MEPI index both significantly improved from 69 ± 3.4 to 79 ± 6.3 and from 64 ± 5.7 to 82 ± 8, respectively (p<0.001). VAS scores also significantly improved from 1.1 ± 0.87 to 0.31 ± 0.53 at rest (p<0.001). The complication rate was 12%, including three transient ulnar nerve paresthesia and one superficial infection. Post-traumatic elbow release was more offered in distal humerus fractures (53%), followed by proximal ulna fracture/dislocations (25%). CONCLUSION: We believe that arthroscopic arthrolysis is a safe and reliable treatment of PTES, which improves joint visibility and reduces pain. Patients can be counseled regarding the risk of a secondary surgery following distal humerus or proximal ulna fractures, including the expected recovery and complication rate.

Arthroscopic Repair of Massive Rotator Cuff Tears Leads to Functional Improvement in Most Patients at 4-Year Follow-up.

Purpose: To assess functional outcomes and healing 4 years after arthroscopic repair of massive rotator cuff tears (MRCTs). Methods: We conducted a retrospective study of patients who underwent arthroscopic rotator cuff repair of an MRCT-defined as a complete 2-tendon tear or a tear greater than 5 cm in any dimension-performed by 2 surgeons at different institutions between January 2015 and December 2018. At a minimum of 4 years postoperatively, patient-reported outcomes collected included the visual analog scale pain score, American Shoulder and Elbow Surgeons (ASES) score, Veterans RAND 12 (VR-12) score, and Subjective Shoulder Value (SSV) score. Repair technique and concomitant procedures were also gathered. Tendon healing was evaluated via ultrasound at final follow-up. Results: Functional outcomes were available for 101 patients at a mean of 63.6 ± 8.8 months (range, 48-82 months) postoperatively. Mean ASES scores improved from 40.1 to 78 (P < .001); VR-12 scores, from 37.1 to 47.7 (P < .001); and SSV scores, from 36.7 to 84.6 (P < .001). Forward flexion improved from 126° to 144° (P = .001), external rotation remained unchanged (from 47° to 44°, P = .268), and internal rotation improved by 2 spinal levels (from L4 to L2, P = .0001). Eighty-eight percent of patients (89 of 101) were satisfied with the procedure, and only 5% underwent reverse shoulder arthroplasty within the study period. Among the 39 patients who underwent postoperative ultrasound to assess healing, 56% showed complete tendon healing. There was no difference in healing or outcomes according to tear pattern. Additionally, tendon healing did not affect outcomes. Conclusions: Arthroscopic repair of MRCTs leads to functional improvements and patient satisfaction in most cases at 4-year follow-up. The rates of patients achieving the minimal clinically important difference were 77.5%, 87.6%, 59.7%, and 80.6% for the ASES score, SSV score, VR-12 score, and visual analog scale pain score, respectively. Complete tendon healing is difficult to achieve but does not appear to limit functional improvements. Level of Evidence: Level IV, therapeutic case series.

Patient-reported outcome tools and baseline scores vary by country and region for arthroscopic repair of massive rotator cuff tears: a systematic review.

Background: Different patient-reported outcome (PRO) tools are used in patients with arthroscopic rotator cuff repair (ARCR) which complicates outcome comparisons. The purpose of this systematic review was to compare PRO usage and baseline scores across world regions and countries in patients with ARCR of massive rotator cuff tears (MRCT). Methods: A systematic review was performed on ARCR for MRCT. The search was conducted from September to November of 2022 using the MEDLINE database for articles published in the last 15 years. Thirty-seven articles were included after initial screening and full-text review. In each article, PRO usage, baseline scores, and country of origin were collected. PRO usage was reported in percentages and baseline scores were normalized for each region to facilitate comparisons. Normalization was performed using the PRO means from each article. These averages were converted to fractions using the worst and best possible scores. These were combined into a single numerical value, expressed as a decimal from 0 to 1, using the total sample size for each tool per region. Values closer to 0 represent worse functional outcomes. Results: Thirty-two percent (n = 12) of articles were from Asia, 43.2% (n = 16) from Europe, 5.4% (n = 2) from the Middle East, and 18.9% (n = 7) from North America. The most commonly reported PRO tools were American Shoulder and Elbow Surgeons (ASES) in 19 papers, Constant-Murley Score (CMS) in 26 papers, Visual Analog Scale for pain (VAS) in 19 papers, and University of California in Los Angeles (UCLA) in 11 papers. ASES was reported in 51% of articles with 63% being from Asia (n = 12) compared to 21% from North America (n = 4). CMS was reported in 70% of studies with 58% being from Europe. Upon normalization, the preoperative score ranged from 0.30 to 0.44. Europe (0.39), and North America (0.40) showed similar scores. The lowest and highest scores were seen in the Middle East (0.3) and Asia (0.44) respectively. Conclusion: There is no standardized method to report outcomes in patients undergoing ARCR for MRCT. Great variation in usage exists in PROs which complicates data comparison between world regions. With normalization, baseline scores where similar among Asia, North America, and Europe, and lowest in the Middle East.

Soft Anchors for Rotator Cuff Repair: A Review.

¼: All-suture anchors or so-called "soft" anchors, initially adapted for labral repairs, have increased in popularity for use in rotator cuff repair because of their smaller size, decreased occupation of the footprint, improved points of fixation, ease of use, and ease of revision. ¼: In limited series, soft anchors have demonstrated equivalent biomechanical and clinical performance compared with hard body anchors for rotator cuff repair. ¼: Perianchor cyst formation can occur with both hard body and soft anchors. ¼: Biomechanical and clinical data support aiming for vertical angles of insertion for soft anchors.
