    Background: This study aimed to determine the prevalence of the Buford complex and to investigate its association with labral pathologies (superior labrum anterior-posterior [SLAP] lesion and anterior, posterior, or multidirectional instability) using a very large patient database. Furthermore, the prevalence of the Buford complex in patients without any labral pathology was also determined. Methods: A total of 3129 consecutive shoulder arthroscopy procedures were retrospectively evaluated for the presence of the Buford complex and coexisting labral pathologies. The relationships between the Buford complex and SLAP lesions, as well as instability, were evaluated statistically. Results: The Buford complex was observed in 83 shoulders (2.65%). SLAP lesions were significantly more frequent in patients with the Buford complex than in those without it (81.9% vs. 33.1%, P < .001) Shoulders with the Buford complex presented a lower frequency of anterior instability (10.8% vs. 19.3%, P = .052) and a higher frequency of posterior instability (1.2% vs. 0.9%, P = .789). The prevalence of the Buford complex in patients with and without labral pathologies was 4.6% and 0.3%, respectively (P < .001). Conclusions: This study, to our knowledge, includes the largest cohort in the literature reporting the prevalence of the Buford complex (2.65%). In the 1461 patients without labral tears or multidirectional instability, the prevalence of the Buford complex was 0.3%. This result suggests that the real prevalence of the Buford complex might be lower than that reported previously. In addition to the aforementioned conclusions, the identification of the Buford complex should prompt a thorough evaluation for concomitant SLAP lesions.

    Objectives The aim of this study is to demonstrate the importance of clinical diagnosis by comparing with preoperative physical examination and magnetic resonance imaging (MRI) images in patients who were arthroscopically diagnosed as having Superior Labrum Anterior-Posterior (SLAP) II lesions. Materials and Methods 134 patients, arthroscopically diagnosed as SLAP II, established the study group, and 200 patients who underwent shoulder arthroscopy for the other pathologies established the control group. Preoperative clinical examination of the patients, MRI findings, and the arthroscopic findings of the patients were recorded. Results Out of the patients diagnosed with a SLAP II lesion, 107 (79.9) of those had an MRI finding while only 60 (30%) of the control group had it. The O'Brien test results of the patients diagnosed with SLAP were positive in 111 (82.8%) while those diagnosed with intact superior labrum were positive in 132 (66%). Of the 134 patients with a SLAP II lesion, 89 (66.4%) had both O'Brien test positiveness and MRI finding, and 129 (96%) had at least one positive result of the O'Brien test or MRI examination Conclusion The O'Brien test and MRI examination are not capable enough to indicate a SLAP lesion one by one, because of the low sensitivity and specificity. But, combining the test with MRI findings provides more trustable information about the superior labrum.

    Midterm outcomes after arthroscopic repair of partial rotator cuff tears: A retrospective study of correlation between partial tear types and surgical technique
    (2020) Kanatlı, Ulunay; Ayanoğlu, Tacettin; Ataoğlu, Muhammet Baybars; Özer, Mustafa; Çetinkaya, Mehmet; Eren, Toygun Kağan
    Objective: Patients who underwent arthroscopic repair for partial rotator cuff tears were evaluated retrospectively. This study purposed to assess the postoperative clinical results of arthroscopic treatment of intratendinous rotator cuff tears and to investigate the effect of the tear type on the postoperative clinical outcomes. Methods: Overall, 60 patients [36 women and 24 men; mean age: 48.6±12.2 years (range 33–67 years)] who underwent arthroscopic repair of Ellman stage 3 partial rotator cuff tear were evaluated retrospectively. These patients were grouped into the following three groups: articular-sided tears, bursal-sided tears, and intratendinous tears, with 20 patients included in each group. Subacromial decompression, acromioplasty, and tear repair without transforming to full-thickness tear were applied to the bursal-sided tears. The same technique was performed for intratendinous ruptures, with the only technical difference was that the capsular tissue was preserved during debridement of intratendinous tears. The articular-sided tears were transformed to complete tears and repaired arthroscopically. The preoperative and postoperative ASES scores and range of motion improvements were evaluated in all patients. The mean follow-up time was 44±6.5 months (range: 36–62 months). Results: No significant intergroup differences were observed concerning the age and the mean follow-up duration (p=0.524, p=0.665). A similar increase in ASES scores was observed for all three types of tears (bursal-sided tears: 31.09–82.65; articular-sided tears: 35.50–-84.00; intratendinous tears: 34.01–83.49). Statistically, no significant intergroup difference was observed concerning ASES score improvement (p=0.585). An increase in mean forward flexion, abduction, and external rotation were observed, especially, a statistically significant increase in flexion (p=0.001) and abduction (p=0.001) in all three types of tears. No patient experienced any intraoperative or postoperative complications. Conclusion: The results of arthroscopic treatment of intratendinous tears were similar to the other types of partial tears, and the results of arthroscopic treatment of grade 3 partial rotator cuff tears revealed satisfactory outcomes, regardless of the type of the tear
