Editorial Commentary: Artificial Intelligence Models Using Machine Learning Can Improve Preoperative Identification of Subscapularis Pathology.

Subscapularis pathology is difficult to diagnose, in part because of decreased sensitivity and accuracy in identifying tears with magnetic resonance imaging (MRI) when compared to other cuff tendons. Artificial intelligence evaluation of patient physical examination and MRI data using a machine learning model shows that arthroscopically confirmed partial- or full-thickness subscapularis tears are highly associated with abnormal subscapularis tendon length, long head of the biceps tears, and subscapularis fatty atrophy, and on physical examination, with weakness with internal rotation and positive lift-off, belly press, and bear hug tests. Today, physicians may use machine learning as a tool, but this model may not currently be sufficient to drastically change practice.

Prevalence and clinical implications of heterotopic ossification after distal biceps tendon repair.

Complete distal biceps tendon ruptures are relatively uncommon. Conservative treatment may result in persistent pain and weakness. Therefore, surgical repair is usually indicated in order to restore strength.

[Arthroscopic Superior Capsule Reconstruction with a Long Head of the Biceps Tendon Autograft: One-Year Follow-up Results].

Purpose Of The Study: Superior Capsule Reconstruction (SCR) of the shoulder joint has recently been included in the portfolio of interventions as a solution to irreparable rotator cuff tears. One of the options is to use a long head of the biceps tendon (LHBT) autograft. This paper presents the fi rst clinical outcomes of the SCR of the shoulder joint using the LHBT autograft.

An Expedited Sling Immobilization Protocol After Isolated Biceps Tenodesis Results in Clinical and Patient-Reported Postoperative Outcomes Equivalent to a Standard Rehabilitation Protocol.

Purpose: To characterize clinical and patient-reported outcomes for patients after isolated biceps tenodesis (BT) who underwent either standard or expedited sling immobilization protocols following surgery.

Methods: This retrospective cohort study compared patients who were assigned to use a sling for either 4 to 6 weeks (standard) or 0 to 2 weeks (expedited) following an isolated BT. Primary endpoint included rate of re-rupture, surgical revision, loss of fixation, and Popeye deformity.

Usefulness of Diagnostic Ultrasound for Detection of Common Shoulder Abnormalities Prior to MRI.

Shoulder pain is a common musculoskeletal pain in the general population and results in significant disability, quality of life impairment and financial burden to the health care system. This cross-sectional study was carried out among purposively selected 61 adult patients with shoulder pain and or limited range of motion in the Department of Radiology and Imaging, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from September 2018 to August 2020 to determine the usefulness of USG in detection of common shoulder abnormalities, as an initial imaging modality using MRI as reference standard. The majority of the patients 25(40.

Is the Complication Rate in the Surgical Repair of the Distal Biceps Tendon Rupture Influenced by the Timing, Type of Incision and Method of Fixation?

Background: Distal biceps tears are uncommon injuries, typically leading to significant loss of elbow flexion and supination strength; surgical repairs restore muscular strength and endurance. The aim of this study was to compare the complication rate of early (< 21 days) vs delayed (> 21 days) repair and the effect of types of incision and fixation methods used in the repair.

Methods: A total of 86 cases were retrospectively reviewed, and 66 cases were included in the study after exclusion.

Editorial Commentary: Shoulder Long Head of the Biceps Tendon Transposition Without Tenotomy May Be a Beneficial Augment for Massive Rotator Cuff Tear Repair.

Although many surgeons discard the long head of the biceps (LHB) tendon during arthroscopic rotator cuff repairs, several authors have argued that the LHB tendon may serve as a biologic and structural augment for massive repairs. There are multiple benefits of incorporating the LHB tendon autograft in difficult-to-repair massive rotator cuff tears. First, by maintaining the glenoid origin, the tendon likely retains a significant native blood supply, as well as tenocytes, which may support the healing process.

Surgically treated acute distal biceps tendon injuries: What results do they have in comparison with the contralateral healthy arm? A systematic review and meta-analysis.

Background: Surgical repair of distal biceps tendon injury restores flexion and supination strength, resulting in good functional outcome. There are few studies that consider clinical results of the operated arm compared to the healthy contralateral arm, whereas there are many articles examining the results of different surgical techniques. We carried out a systematic review with meta-analysis of the studies that consider this comparison.

Amyloidosis and Considerations for the Hand Surgeon.

Amyloidosis can lead to cardiac, renal, and other multiorgan failure. New treatments have become available that can prolong survival but rely on early diagnosis. Manifestations of amyloidosis in hand surgery include carpal tunnel syndrome, trigger finger, peripheral neuropathy, and spontaneous distal biceps rupture.

Superior capsular reconstruction for irreparable posterosuperior rotator cuff tears.

Although the superior portion of the shoulder joint capsule is a clearly distinct structure, its ability to prevent vertical humeral head translation in irreparable rotator cuff tears remains controversial. The clinical results of superior capsule reconstruction (SCR) in this context are satisfactory but the radiological outcomes are poor in up to two-thirds of patients. Moreover, there is no proof that SCR is more beneficial than simply doing a subacromial debridement, a partial repair or a tenotomy of the long head of biceps.

Distal biceps reconstruction: a long-term follow-up of the complications and durability of the single-incision power optimizing cost-effective (SPOC) repair.

Background: The Single-Incision Power Optimizing Cost-Effective Repair (SPOC) method reattaches the distal biceps tendon to its original posterior anatomic footprint and utilizes the anterior cortex of the supinated radius for fixation. The purpose of the study was to define the long-term complications and durability of the SPOC method.

Methods: Two hundred and eighteen patients underwent the SPOC repair of distal biceps ruptures from 2008 to 2020, with 185 having at least 1-year follow-up data.

Which Factors Are Associated With Rerupture After Superior Capsular Reconstruction of the Shoulder With Autologous Long Biceps Tendon? - A Systematic Review.

Based on a systematic review, the present work analyses factors associated with the rerupture rate or non-healing after superior capsular reconstruction with autologous long biceps tendon in the reconstruction of the rotator cuff of the shoulder.A systematic review of the U.S.

Arthroscopic biceps tenodesis using press-fit bony plug: a case series study.

Purpose: To assess the feasibility, operative time, clinical outcomes, possible complications, and failure rates of all-through arthroscopic biceps tenodesis using press-fit bony plug technique.

Methods: This prospective case series study involved 30 skeletally mature patients with long head of biceps pathology (tendinitis after failure of conservative treatment, subluxation, dislocation, or tendon tears). All patients were followed up for 24 months at least.

Distal biceps tendon rupture: a comprehensive overview.

Distal biceps tendon (DBT) is a relatively rare injury mainly occurring in middle-aged men while in eccentric biceps muscle contraction. Clinical appearance with proximal avulsion of the muscle and specific clinical tests are most of the time sufficient for diagnosing DBT, but if needed ultrasonography and MRI, most often in FABS view, can be used to ensure diagnosis of DBT and partial DBT. Surgical anatomical reinsertion has shown to be a successful method of treatment, although conservative treatment can be initiated in older patients.

Acute Distal Biceps Tendon Injury: Diagnosis and Treatment.

Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion.

Functional reconstruction of elbow flexion with latissimus dorsi muscle rotational transfer: two case reports.

Background: We report two cases of biceps brachii and brachialis paralysis due to musculocutaneous nerve injury in which elbow joint flexion was reconstructed using rotational transfer of the latissimus dorsi muscle with sutures to the radial and ulnar tuberosities, thereby enabling flexion by simultaneous activation of the humeroradial and humeroulnar joints. In cases of associated brachialis paralysis, weaker flexion strength can be expected when the forearm is in a pronated position than when it is in a supinated state. To the best of our knowledge, no previous study has reported the rotational position of the forearm during elbow joint flexion reconstruction.

Higher Upper Subscapularis Goutallier Grade and Coracohumeral Distance Narrowing Are Predictive of Subscapularis Tears in Patients Undergoing Arthroscopic Rotator Cuff Repair.

Purpose: To evaluate the relation between subscapularis (SSC) Goutallier grade or coracohumeral distance (CHD) and SSC tears, as well as the relation between these radiographic variables and long head of the biceps tendon lesions.

Methods: A retrospective analysis was conducted on prospectively maintained data on patients who underwent arthroscopic rotator cuff repair of SSC tears between 2011 and 2021 with at least 6 months of follow-up. Patients with identified subscapularis tears during arthroscopy were included.

Olympic Elbow Comprising Lateral Epicondylitis, Cubital Tunnel Syndrome, and Distal Biceps Tendon Rupture.

There is a wide range of elbow injuries including chronic injuries such as lateral epicondylitis, medial epicondylitis, and cubital tunnel syndrome, or acute injuries such as elbow fracture-dislocations and distal biceps tendon ruptures. Combinations of acute and chronic elbow injuries have been reported including country club elbow and terrible triad of the elbow which are important to identify to properly treat. Thus, we report for the first time a new elbow injury triad termed Olympic elbow in a 65-year-old man comprising lateral epicondylitis, cubital tunnel syndrome, and a distal biceps tendon rupture.

Smaller radioulnar window is associated with a distal biceps tendon rupture in patients with limited forearm rotation: a 3-dimensional computed tomography comparison study of proximal impingement caused by radial tuberosity hypertrophy-a single-center case series.

Background: It has been suggested that hypertrophy of the radial tuberosity may result in impingement leading to either a lesion of the distal biceps tendon or rotational impairment. Two previous studies on hypertrophy of the radial tuberosity had contradictory results and did not examine the distance between the radius and ulna: the radioulnar window. Therefore, this comparative cohort study aimed to investigate the radioulnar window in healthy subjects and compare it with that in subjects with either nontraumatic-onset rotational impairment of the forearm or nontraumatic-onset distal biceps tendon ruptures with rotational impairment of the forearm by use of dynamic 3-dimensional computed tomography measurements to attain a comprehensive understanding of the underlying etiology of distal biceps tendon ruptures.

Predictors of pain development for contralateral asymptomatic degenerative rotator cuff tears based on features of an ipsilateral painful cuff tear: a prospective longitudinal cohort study.

Background: Prior rotator cuff disease natural history studies have focused on tear-related factors that predict disease progression within a given shoulder. The purpose of this study was to examine both patient- and tear-related characteristics of a painful rotator cuff tear that predict future pain development and functional impairment in a shoulder with a contralateral asymptomatic cuff tear.

Methods: This was a prospective longitudinal cohort study of patients aged ≤65 years who underwent surgery for a painful degenerative rotator cuff tear and possessed an asymptomatic contralateral tear.
