BACKGROUND: An anatomic double-tunnel (DT) reconstruction technique has been widely adopted to reconstruct the ruptured coracoclavicular (CC) ligaments seen with high-grade acromioclavicular (AC) joint injuries. However, the anatomic DT reconstruction has been associated with the risk of clavicle fractures, which may be problematic, particularly for contact athletes. Purpose/Hypothesis: The purpose was to compare a single-tunnel (ST) CC ligament reconstruction for AC joint injuries with the native state as well as with the more established anatomic DT CC ligament reconstruction...

PURPOSE: To compare biomechanical outcomes of 4 different arthroscopic techniques for fixation of tibial eminence fractures. METHODS: Twenty-four skeletally mature, fresh-frozen cadaveric knees were divided into 4 comparison groups based on the fixation method: screw fixation (group A), traditional sutures fixation with 2 FiberWire sutures (group B), a modified suture technique with 2 FiberWire sutures that created neckwear knots to firmly trap the fracture fragment (group C), or suture anchors which was based on the suture bridge technique primarily used in the shoulder for repair of rotator cuff tears and greater tuberosity fractures (group D)...

BACKGROUND: Bone loss in shoulder instability is a well-recognized cause of failure after stabilization surgery. Many approaches have been described to address glenoid bone loss, including coracoid transfer. This transfer can be technically difficult and has been associated with high complication rates. An ideal alternative to coracoid transfer would be an autologous source of fresh osteochondral graft with enough surface area to replace significant glenoid bone loss. The distal clavicle potentially provides such a graft source that is readily available and low-cost...

Arthroscopic pancapsular release has been recommended for recalcitrant frozen shoulder, but regaining range of motion has not been sufficient compared with the unaffected side. There is no consensus about the reasons for these remaining restrictions in range of motion, but residual capsular or connective tissue must be considered a candidate. A thickened coracohumeral ligament at the rotator interval has been reported as one of the most specific manifestations of frozen shoulder. It covers wider portions of the subscapularis tendon, supraspinatus tendon, and infraspinatus tendon than previously reported...

Objective: Surgical treatment options should be discussed in cases of frozen shoulder, which is usually treated in a conservative manner. In this study, we evaluated the efficacy of manipulation and arthroscopic release in cases of frozen shoulder which resisted conservative treatment. Methods: A total of 32 patients who underwent manipulation and arthroscopic capsular release in 34 shoulders were included in the study. The average follow-up period was 49.5 months (range: 24-90 months)...

The authors describe a surgical biological reconstruction of the humeral head with frozen autogenous allograft technique for the treatment of young patients with focal osteonecrosis of the humeral head. This represents a possible alternative, maybe even definitive for some patients, when compared to hemiarthroplasty or total shoulder arthroplasty. The technique consists of the fixation of a frozen autogenous allograft with previously-molded articular cartilage from the humeral head, after cleansing the osteonecrotic focus...

BACKGROUND: Failure after rotator cuff repair remains a major clinical problem and could be related to excessive pressures from the acromion. Previous studies with irreparable tears showed good clinical results of tendon healing with arthroscopic insertion of a protective biodegradable spacer balloon between the repaired tendon and the acromion. One hypothesis is that compression pressures on the repaired tendon will be reduced by the spacer. This cadaver study aimed to investigate the effects of this subacromial spacer on compression pressures over a repaired supraspinatus tendon in passive motion...

BACKGROUND: Subscapularis (SSC) tendon tears are a challenging problem because they can significantly alter shoulder mechanics and function. Tendon retraction and advanced fatty degeneration associated with a chronic tear may make it irreparable. Tendon transfers options for such tears are viable, but results in the setting of associated glenohumeral instability are inconsistent. With the potential to recreate the SSC line of pull, the teres major (TM) may be a viable option for transfer...

BACKGROUND: Accurate measurements of shoulder and elbow motion are required for the management of musculoskeletal pathology. The purpose of this investigation was to compare three techniques for measuring motion. The authors hypothesized that digital photography would be equivalent in accuracy and show higher precision compared to the other two techniques. METHODS: Using infrared motion capture analysis as the reference standard, shoulder flexion/abduction/internal rotation/external rotation and elbow flexion/extension were measured using visual estimation, goniometry, and digital photography on 10 fresh frozen cadavers...

BACKGROUND: Frozen shoulder (also known as adhesive capsulitis) occurs when the capsule, or the soft tissue envelope around the ball and socket shoulder joint, becomes scarred and contracted, making the shoulder tight, painful and stiff. It affects around 1 in 12 men and 1 in 10 women of working age. Although this condition can settle with time (typically taking 1 to 3 years), for some people it causes severe symptoms and needs referral to hospital. Our aim is to evaluate the clinical and cost-effectiveness of two invasive and costly surgical interventions that are commonly used in secondary care in the National Health Service (NHS) compared with a non-surgical comparator of Early Structured Physiotherapy...

Frozen shoulder, also known as adhesive capsulitis, is a common presentation in the primary care setting and can be significantly painful and disabling. The condition progresses in three stages: freezing (painful), frozen (adhesive) and thawing, and is often self-limiting. Common conservative treatments include nonsteroidal anti-inflammatory drugs, oral glucocorticoids, intra-articular glucocorticoid injections and/or physical therapy. However, many physicians may find themselves limited to prescribing medications for treatment...

Frozen shoulder causes significant functional disability and pain in a population group constituted by patients who are often middle-aged and working.Frozen shoulder remains poorly understood. The available literature is limited and often prone to bias.A rapid, non-surgical and cost-effective treatment that reduces pain and restores function is an attractive option.Hydrodilatation is a potential first-line treatment of frozen shoulder in secondary care.

Several different flexible end effectors have been developed to solve the problem of approaching the lesion in a minimally invasive surgery. In this paper, we developed a wire-driven end effector device to treat frozen shoulder. Since the device is for capsular release surgery, it has a suitable bend radius for the surgery. It is a cylindrical cannula that can fit various surgical tools and can be sterilized after use. The end effector is made of an elastic material called PAI (polyamide-imide) with its outer diameter and total length being 4 and 19 mm...

BACKGROUND: The pathophysiological mechanisms behind proliferation of fibroblasts and deposition of dense collagen matrix in idiopathic frozen shoulder remain unclear. Alarmins (also known as danger signals) are endogenous molecules that are released into the extracellular milieu after infection or tissue injury and that signal cell and tissue damage. PURPOSE: To investigate whether the presence of alarmins is higher in patients with idiopathic frozen shoulder than in control subjects...

BACKGROUND: Contractile tissue plays an important role in mobility deficits in frozen shoulder (FS). However, no study has assessed the effect of the muscle release technique on the muscle activation and kinematics in individuals with FS. The purposes of this study were to assess the differences in shoulder muscle activity and kinematics between the FS and asymptomatic groups; and to determine the immediate effects of muscle release intervention in the FS group. METHODS: Twenty patients with FS and 20 asymptomatic controls were recruited...

BACKGROUND: Arthroscopic sub-acromial decompression (decompressing the sub-acromial space by removing bone spurs and soft tissue arthroscopically) is a common surgery for subacromial shoulder pain, but its effectiveness is uncertain. We did a study to assess its effectiveness and to investigate the mechanism for surgical decompression. METHODS: We did a multicentre, randomised, pragmatic, parallel group, placebo-controlled, three-group trial at 32 hospitals in the UK with 51 surgeons...

BACKGROUND: Limited data exist characterizing complications after axillary lymphadenectomy for melanoma. With high rates of complications reported after dissection for breast cancer and data suggesting that completion lymphadenectomy may have limited therapeutic benefit, this study characterized morbidity to facilitate clinical decision-making. METHODS: Using a broad definition for complications, patients who underwent axillary dissection for melanoma at a single center (from 2003 to 2015) were assessed through retrospective chart review...
