Bridging Technique

Objectives: Recently suture bridging technique has become the most popular footprint reconstruction procedure, and many surgeons prefer to perform lateral row fixation after tying the medial-row suture. According to some authors, strangulation caused by medial-row knot can lead to re-tear at the muscle-tendon junction, which is called type II failure. They have reported type II failure occurred 59˜74% in re-tear cases with conventional suture bridging. In order to avoid stress concentration on the medial-row, we prefer to use triple-loaded suture anchors for the medial-row, and perform lateral-row fixation of suture bridging before tying medial-row suture. This is a procedure in which we reduce the cuff to the tuberosity first, then press down the cuff to the footprint by tying the remaining suture. The purpose of this study was to assess the functional outcomes and structural integrity after our suture bridging technique. Methods: From April 2012 to May 2015, a consecutive series of 373 patients (4 bilateral cases) with complete rotator cuff tear were performed arthroscopic rotator cuff repair in our hospital. There were 90 small, 135 medium, 117 large, and 35 massive tears according to Cofield classification. Functional outcomes were assessed using JOA and UCLA score preoperatively and at final follow-up which was 29 months on average after surgery. Repair integrity was evaluated with MRI performed at a mean of 14 months after surgery and was graded using Sugaya classification. In addition, re-tear was divided into 2 groups. Type I failure is detachment from the footprint (group F1). Type II failure is muscle-tendon junction failure (group F2). We also investigated the relationship between clinical outcomes and repair integrity/tear pattern. Statistical analysis was performed using paired t test for comparing clinical outcomes and one-factor ANOVA/Tukey-Kramer test or Kruskal-Wallis test/Steel Dwass test to compare difference between the groups. Results: Regarding clinical outcomes, both JOA and UCLA scores have significantly improved overall from 72 to 95 and 18 to 34, respectively (P <0.0001). Postoperative MRI demonstrated successful repair in 318 shoulders (84.4%: group S) and re-tear (Sugaya type IV and V) in 59 shoulders (15.6%). There were 16 re-tears (7.1%) in small to medium tears and 43 re-tears in large and massive tears (28.3%). Among 59 re-tears, 39 shoulders (66%) were type I failures (group F1) and 20 shoulders (34%) were type II failures (group F2). Postoperative JOA score was significantly improved in both successful and failed repairs: 72 to 95 in group S, 72 to 94 in group F1 and 70 to 91 in group F2 (P <0.0001). Although preoperative scores demonstrated no significant difference between 3 groups, postoperative scores were significantly different between group S and group F2 (P=0.0008) and group F1 and group F2 (P=0.027). Similarly, postoperative UCLA score in group F2 was also significantly inferior to group S (p=0.0008) and group F1 (P =0.036). Conclusion: Our suture bridging technique abbreviating medial-row knot tying demonstrated excellent functional outcomes and structural integrity after surgery. In addition, rate of muscle-tendon junction failure, which proved to be functionally deteriorated compared with type I failure, was obviously lower when compared with previous reports with conventional suture bridging.

Wrist Motion

We retrospectively compared results of 27 wrists with bicolumnar arthrodesis with mean follow-up of 67 months to 28 wrists with three-corner arthrodesis adding triquetral excision with mean follow-up of 74 months in 54 patients (55 wrists). Minimal follow-up was 2 years for all patients. Capitolunate nonunion occurred in three wrists with bicolumnar arthrodesis and six wrists with three-corner arthrodesis, and radiolunate arthritis developed in four wrists with three-corner arthrodesis. Among patients with bicolumnar arthrodesis, hamatolunate arthritis occurred in seven wrists, all with a Viegas type II lunate; and pisotriquetral arthritis occurred in three wrists. At mean 5 years after surgery, 45 wrists had not needed revision surgery, and both groups had similar revision rates. The wrists with three-corner arthrodesis and bicolumnar arthrodesis had similar functional outcomes, and range of wrist motion was not significantly different between the two groups. We concluded that bicolumnar arthrodesis results in greater longevity than three-corner arthrodesis for a type I lunate. We do not recommend bicolumnar arthrodesis for type II lunate. We also concluded that three-corner arthrodesis has a greater incidence of radiolunate arthritis and capitolunate nonunion. Level of evidence: III

Massive Rotator Cuff Tears

Background: There is no research on incomplete footprint coverage with single-row repair related to bone marrow stimulation (BMS) in large to massive rotator cuff tears (RCTs). Purpose/Hypothesis: The purpose was to compare the clinical results and structural integrity between BMS and non-BMS groups that underwent arthroscopic repair of large to massive rotator cuff tears with <50% footprint coverage. It was hypothesized that both groups would exhibit improved clinical outcomes at 2 years after surgery but the BMS group would have significantly better clinical outcomes and structural integrity. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 98 patients who underwent arthroscopic repair with <50% footprint coverage for large to massive RCTs with (BMS group; n = 56) or without (non-BMS group; n = 42) BMS. Functional outcomes at the 2-year follow-up were assessed using the visual analog scale for pain score, subjective shoulder value; American Shoulder and Elbow Surgeons score; University of California, Los Angeles, shoulder score; and active range of motion. Structural integrity was evaluated using magnetic resonance arthrography or computed tomography arthrography results at 6 months postoperatively. Results: At the 2-year follow-up, all functional outcomes significantly improved in both groups compared with preoperative values ( P < .001). However, there were no significant postoperative differences between groups. On follow-up magnetic resonance arthrography or computed tomography arthrography, the overall retear rate was not significantly different between the BMS group (30.3%; 17/56) and the non-BMS group (35.7%; 15/42). Conclusion: While both groups exhibited functional improvement after single-row repair with <50% footprint coverage for large to massive RCTs, BMS did not produce better clinical outcomes or structural integrity.

Background The acute onset of Marchiafava-Bignami disease (MBD) is difficult to capture, and its clinical manifestations are overlapped. Magnetic resonance imaging (MRI) is very useful in the diagnosis of acute MBD. Purpose To investigate the MRI features and clinical outcomes of acute MBD. Materials and Methods Sagittal T2-weighted (T2W) or T1-weighted (T1W) imaging, axial T1W and T2W imaging, and axial FLAIR and diffusion-weighted imaging (DWI) sequences were performed in 17 patients with acute MBD on 1.5-T MR. According to the different ranges of callosal restricted diffusion, MBD was divided into Type I (n = 7, the completely involved), Type II (n = 5, the mostly involved), and Type III (n = 5, the partly involved). The MRI findings and outcomes of each type were retrospectively analyzed. Results With the reduced range of the callosal restricted diffusion, the callosal atrophy or cavitation was more common: no case of Type I; 1 (20%) case of Type II; and 3 (60%) cases of Type III. With the increased range of callosal restricted diffusion, the extracallosal involvement was more common: 6 (86%) cases of Type I; 3 (60%) cases of Type II; and 1 (20%) case of Type III. During the follow-up, five cases had neuropsychiatric sequelae: 1 (14%) case of type I; 1 (20%) case of Type II; 3 (60%) cases of Type III. Conclusion The MRI findings and clinical outcomes of acute MBD are regular. The extensive restricted diffusion of acute MBD may present the curable condition. Callosal heterogeneity may affect the outcome of acute MBD.

Background:Acellular dermal matrices (ADMs) have been used in the treatment of shoulders with massive rotator cuff tears (MRCTs). Despite clinical improvement, correlation of clinical findings with ADM integrity on imaging has not been investigated.Hypothesis:The pain in shoulders with MRCTs is partially due to bone-to-bone contact between the tuberosity and acromion. Coverage of the tuberosity with an intact graft or a graft that is torn in a way that the tuberosity remains covered will act as an interpositional tissue, preventing bone-to-bone contact and leading to clinical improvement.Study Design:Case series; Level of evidence, 4.Methods:Between 2006 and 2016, a total of 25 shoulders with MRCTs underwent a procedure with an ADM. Pre- and postoperative visual analog scale (VAS) results, American Shoulder and Elbow Surgeons (ASES) score, Hamada grade, and Goutallier classification were reviewed. A postoperative magnetic resonance imaging (MRI) was obtained in 22 (88%) shoulders. The status of the graft was divided into the following categories: type I, intact graft; type II, graft tear with tuberosity covered; and type III, graft tear with tuberosity uncovered (bare).Results:The mean patient age was 61 years (range, 49-73 years), and the mean follow-up was 25.6 months (range, 10-80 months). Mean length from surgery to postoperative MRI was 13.9 months (range, 6-80 months). The graft was torn in 59% (13/22 shoulders). Significant improvements were found in VAS and ASES scores (7 vs 0.7 and 32.6 vs 91.2, respectively; P < .01) for type I grafts and in VAS and ASES scores (8.1 vs 1.3 and 26.3 vs 84.6, respectively; P < .01) for type II grafts. No difference was found in postoperative VAS and ASES (0.7 vs 1.3 and 91.2 vs 84.6, respectively; P = .8) between type I and type II grafts. No improvement was seen in VAS (7.3 vs 5.7; P = .2) or ASES (30.6 vs 37.2; P = .5) for type III grafts.Conclusion:MRI appearance of the graft has a significant impact on functional outcomes. Patients with an intact graft or a graft tear leaving the tuberosity covered have lower pain and higher functional scores than those in whom the torn graft leaves the tuberosity uncovered.

Arthroscopic Rotator Cuff

Background: When arthroscopic rotator cuff repair is performed on a young patient, long-lasting structural and functional tendon integrity is desired. A fixation technique that potentially provides superior tendon healing should be considered for the younger population to achieve long-term clinical success. Hypothesis/Purpose: The purpose was to compare the radiological and clinical midterm results between single-row and double-row (ie, suture bridge) fixation techniques for arthroscopic rotator cuff repair in patients younger than 55 years. We hypothesized that a double-row technique would lead to improved tendon healing, resulting in superior mid- to long-term clinical outcomes. Study Design: Cohort study; Level of evidence, 2. Methods: A consecutive series of 66 patients younger than 55 years with a medium to large full-thickness tear of supraspinatus and infraspinatus tendons who underwent arthroscopic single-row or double-row (ie, suture bridge) repair were enrolled and prospectively observed. Thirty-four and 32 patients were assigned to single-row and double-row groups, respectively. Postoperatively, tendon integrity was assessed by MRI following Sugaya’s classification at a minimum of 12 months, and clinical outcomes were assessed with the Constant score and the University of California, Los Angeles (UCLA) score at a minimum of 2 years. Results: Mean follow-up time was 46 months (range, 28-50 months). A higher tendon healing rate was obtained in the double-row group compared with the single-row group (84% and 61%, respectively [ P < .05]). Although no difference in outcome scores was observed between the 2 techniques, patients with healed tendon demonstrated superior clinical outcomes compared with patients who had retorn tendon (UCLA score, 34.2 and 27.6, respectively [ P < .05]; Constant score, 94 and 76, respectively [ P < .05]). Conclusion: The double-row repair technique potentially provides superior tendon healing compared with the single-row technique. Double-row repair should be considered for patients younger than 55 years with medium to large rotator cuff tears.

Background There are few studies reporting long-term rotator cuff integrity following repair. The present study reports a case series of surgically repaired supraspinatus tendons followed up with clinical outcomes and ultrasound imaging after an average of 16 years. Methods The prospectively studied clinical outcomes at short-, medium- and long-term follow-up in 27 shoulders in 25 patients treated with arthroscopic subacromial decompression and mini-open rotator cuff repair have been reported previously. The functional outcomes scores recorded were the University of California Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) measures. These patients then underwent an ultrasound scan with respect to the long-term assessment of the shoulder and the integrity of the repair. Results A recurrent tear was noted in 37% of patients at 16.25 years after surgery, of which 50% were small. Two patients required repeat surgery. Patients had a mean UCLA score of 30, an ASES score of 91.3 and a SST score of 9.5 with a 85% level of satisfaction with surgery. Patients with a recurrent tear had outcome scores equivalent to those with an intact cuff with no significant pain. No independent risk factors were identified as predictors for recurrent tear. Conclusions Patients showed sustained benefit and satisfaction at long-term follow-up despite a 37% recurrence of full-thickness supraspinatus tear.

Novel coronavirus disease (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Its impact on patients with comorbidities is clearly related to fatality cases, and diabetes has been linked to one of the most important causes of severity and mortality in SARS-CoV-2 infected patients. Substantial research progress has been made on COVID-19 therapeutics; however, effective treatments remain unsatisfactory. This unmet clinical need is robustly associated with the complexity of pathophysiological mechanisms described for COVID-19. Several key lung pathophysiological mechanisms promoted by SARS-CoV-2 have driven the response in normoglycemic and hyperglycemic subjects. There is sufficient evidence that glucose metabolism pathways in the lung are closely tied to bacterial proliferation, inflammation, oxidative stress, and pro-thrombotic responses, which lead to severe clinical outcomes. It is also likely that SARS-CoV-2 proliferation is affected by glucose metabolism of type I and type II cells. This review summarizes the current understanding of pathophysiology of SARS-CoV-2 in the lung of diabetic patients and highlights the changes in clinical outcomes of COVID-19 in normoglycemic and hyperglycemic conditions.
