The pathology of oxidative stress-induced autophagy in a chronic rotator cuff enthesis tear.

Partial-thickness rotator cuff tears (PTRCTs) are often found in daily orthopedic practice, with most of the tears occurring in middle-aged patients. An anaerobic process and imbalanced oxygenation have been observed in PTRCTs, resulting in oxidative stress. Studies have shown the roles of oxidative stress in autophagy and the potential of unregulated mechanisms causing disturbance in soft tissue healing.

Total elbow arthroplasty with tricep turn-down flap in an old unreduced elbow dislocation: A case report.

Introduction And Importance: The treatment preference for neglected elbow dislocation is by open reduction and lengthening the tricep muscle. If the dislocation is not reduced for more than 6 months, degenerative resorption would have occurred. We did total elbow arthroplasty (TEA) with a tricep turn-down flap for the management in this case.

Ultrasound-Guided Suprascapular Nerve Block at Spinoglenoid Notch and Glenohumeral Joint Hydrodilation.

Hydrodilation of the glenohumeral joint is commonly employed as a nonsurgical intervention for the frozen shoulder. Accuracy and pain during the procedure can be regarded as difficulties in performing this procedure. Ultrasonography (USG) guided injection and suprascapular nerve block can improve the accuracy and can decrease pain during the hydrodilation procedure.

The role of suprascapular nerve block in hydrodilatation for frozen shoulder.

Introduction: Frozen shoulder is a debilitating problem that requires comprehensive diagnosis and management. Patients usually recover, but the possibility of not reobtaining a full range of motion exists. Thus, early shoulder exercises are necessary to achieve their full range of motion.

Soft tissue reconstruction on the very late presenting neglected acromioclavicular dislocation Rockwood type IV. A case report.

Introduction And Importance: Acromioclavicular (AC) joint dislocation Rockwood type IV is a rare condition characterized by the posterior displacement of the distal clavicle and soft tissue damage. The rate of soft tissue healing markedly decreases as time from injury increases. In this case report, we had a very late presenting neglected AC joint dislocation Rockwood type IV successfully treated by AC and coracoclavicular (CC) reconstruction.

Traumatic Inferior Glenohumeral Dislocation Associated With Rotator Cuff Avulsion Fracture: Arthroscopic-Assisted Fixation: A Technical Note.

Traumatic inferior glenohumeral dislocation with rotator cuff avulsion fracture rarely occurs and may cause chronic pain and diminished shoulder function. Several treatment options are available for this injury, such as open reduction internal fixation and arthroscopic-assisted reduction internal fixation. This technique describes a step-by-step technique to manage traumatic inferior glenohumeral dislocation with rotator cuff avulsion fracture using the simultaneous closed reduction procedure for traumatic inferior glenohumeral dislocation and the arthroscopic procedure with suture bridge technique for the treatment of rotator cuff avulsion fracture.

High-Grade Bursal Side Rotator-Cuff Repair: A Surgical Outcome Review.

Purpose: We aimed to evaluate surgical outcomes of high-grade bursal rotator cuff-tear repairs.

Methods: This systematic review was performed in May 2020 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed. Inclusion criteria were English-language studies reporting the results of pain improvement, functional outcome scores, and radiographic examinations after repair of bursal side partial rotator-cuff tears at any time point in patients of any age and with all levels of evidence.

Open Reduction on very late-presenting unreduced posterior elbow dislocation: Still promising treatment option.

Background: Neglected dislocation of the elbow is associated with instability, pain, and limitation of elbow function. In developing countries, neglected dislocations of the elbow are quite common, and most patients initially go to local bonesetters, which only aggravates the problem.

Presentation Of Case: Two patients with a history of unreduced posterior elbow dislocation for more than 1 year and were treated by a traditional bonesetter were included in this case study.

Modified Eden-Lange procedure for iatrogenic lateral scapular winging.

Introduction: Lateral winging scapula is rare and generated by the trapezius paralysis. It is most likely iatrogenic from procedures involving the posterior cervical triangle. The modified Eden-Lange procedures one of the options by restoring the major actions of a flaccid trapezius.

Autologous tendon graft for non-union distal clavicle fracture in a patient with chronic kidney disease.

Background: Fracture of distal-end accounts for 20% of all clavicle fracture. In the situation of impaired bone healing environment such as chronic kidney disease (CKD), nonunion rates after surgery might increase. In the case where bone healing is unexpected, biological healing with tendon graft could be an alternative method to maintain bone reduction.

Bipolar fracture dislocation of clavicle: A report of osteosynthesis and early soft tissue reconstruction.

Introduction: Bipolar dislocation of the clavicle, also called bifocal or pan-articular dislocation or floating clavicle, is an uncommon traumatic injury. The injury of this case is also concomitant with distal third clavicle and coracoid fracture. This article aimed to report the experience of performing osteosynthesis and early soft tissue reconstruction on these injuries.

Effect of Lead Nanoparticles Inhalation on Bone Calcium Sensing Receptor, Hydroxyapatite Crystal and Receptor Activator of Nuclear Factor-Kappa B in Rats.

This study aimed to investigate whether Pb nanoparticle exposure affects the bone calcium sensing receptor (CaSR), hydroxyapatite crystal, and receptor activator of nuclear factor-kappa B (RANK) in rats exposed to subchronic and chronic inhalation. Thirty two rats were randomly divided into eight groups. One group is a non-exposed group.

Concepts for increasing gentamicin release from handmade bone cement beads.

Background And Purpose: Commercial gentamicin-loaded bone cement beads (Septopal) constitute an effective delivery system for local antibiotic therapy. These beads are not available in all parts of the world, and are too expensive for frequent use in others. Thus, orthopedic surgeons worldwide make antibiotic-loaded beads themselves.
