Arthroscopic Humeroplasty in the Treatment of Acute Reverse Hill-Sachs Lesion Associated With Posterior Shoulder Instability.

Reverse Hill-Sachs lesions (RHSL) are common complications associated with posterior shoulder dislocations and represent a significant challenge for preserving joint stability and function. If untreated, these compression fractures of the anteromedial humeral head can compromise the integrity of the joint, predisposing patients to recurrent instability and arthropathy. While various treatment modalities exist, achieving an anatomic reduction of the defect while preserving the articular cartilage remains a desirable outcome, particularly in acute settings.

DNA vaccines as promising immuno-therapeutics against cancer: a new insight.

Cancer is one of the leading causes of mortality around the world and most of our conventional treatments are not efficient enough to combat this deadly disease. Harnessing the power of the immune system to target cancer cells is one of the most appealing methods for cancer therapy. Nucleotide-based cancer vaccines, especially deoxyribonucleic acid (DNA) cancer vaccines are viable novel cancer treatments that have recently garnered significant attention.

The Comparison of Cost-Effectiveness Between Magnetic Resonance Spectroscopy and Provocative Discography in the Identification of Chronic Low Back Pain Surgery Candidates.

Background/context: Chronic low back pain (CLBP) is a significant US healthcare burden with millions of lumbar spine procedures annually. Diagnostic tests are essential to guide treatment but provocative discography (PD), the most common diagnostic procedure, is without robust evidence of its value. A non-invasive alternative using Magnetic Resonance Spectroscopy (MRS) offers a potential solution.

Revision quadriceps tendon repair: A case series and technique guide to a novel repair.

Introduction: Revision quadriceps tendon repair is a challenging problem. In this four-case series, novel quadriceps tendon revision resulted in improved range of motion and durable repair for patients with recurrent rupture.

Methods: Our technique includes a combination of a running locked #5 FiberWire or 2 mm SutureTape suture placed through parallel medial, lateral, and central drill holes in the patella with running Krackow-type quadriceps tendon repair medially and laterally resulting in four strands, delivering the vastus medialis and medial quadriceps tendon to an anatomic repair at the superior pole of the patella, with 2 sutures passed centrally and 1 each passed medially and laterally and then tied.

Delayed diagnosis of posterior tibialis tendon interposition in the distal tibiofibular and tibiotalar joints after open fracture-dislocation of the ankle joint: A case report with a 10-year follow-up.

Irreducible ankle fracture-dislocations due to posterior tibialis tendon (PTT) interposition in the distal tibiofibular and tibiotalar joints are rarely reported, and their diagnoses are often missed and delayed. In addition, previous reports lacked a longer clinical follow-up period, and objective and subjective evaluations of such cases have not been reported. A 22-year-old man sustained an open fracture-dislocation of the ankle joint associated with a distal third of the fibular shaft fracture and diastasis of the distal tibiofibular joint.

A rare incidence of acute pulmonary embolism following surgical fixation of bilateral upper extremity fractures - A case report.

Case: A 52-year-old male fell from his bike and sustained fractures of the right proximal humerus and the left distal radius, both of which were fixed in a single sitting a day after the injury. On postoperative day four, the patient developed features suggestive of acute pulmonary embolism.

Conclusion: Reports of acute pulmonary embolism developing after surgical fixation of bilateral upper extremity fractures are rare.

Serious lower limb injuries following car gearbox explosion: A rare case report.

Car Gearbox explosion-related injuries are very rare but could be serious. We reported a 43-year-old female patient who sustained severe bilateral lower limb injuries following an explosion of the gearbox in her private car while waiting at a traffic signal. The patient suffered from a left open tibia shaft fracture and severely macerated soft tissues, along with an open wound on the right leg.

β-Caryophyllene and Statins in Bone Fracture Healing - A Narrative Review.

Bone fractures are a leading cause of morbidity and healthcare expenditure globally. The complex healing process involves inflammation, cartilage formation, mineralization, and bone remodeling. Current treatments like immobilization, surgery, and bone grafting, though effective, pose significant challenges, such as prolonged recovery and high costs.

Cost analysis of dermal allograft patch utilization in rotator cuff repair.

Background: To perform an analysis of intraoperative costs associated with arthroscopic rotator cuff repair (RCR) acellular dermal allograft patch augmentation and interposition.

Methods: This was a matched cohort retrospective cost identification analysis. We identified patients who underwent arthroscopic RCR with acellular dermal allograft patch augmentation or interposition between 2014 and 2023 at a single academic center.

Anterior glenoid rim resorption after arthroscopic Bankart repair by the footprint fixation technique and its correlation with the healing of the repaired capsulolabral complex: a computed tomography and magnetic resonance arthrography imaging study.

Background: Studies have revealed that anterior glenoid rim bone resorption occurs in the early stage after arthroscopic Bankart repair (ABR) if bony Bankart lesions are absent or fail to heal. However, this structural change has never been studied after repair by footprint fixation (FF). Additionally, the relationship between the extent of rim resorption and healing of the repaired capsulolabral complex (CLC) remains unclear.

Online patients questions regarding reverse total shoulder arthroplasty pertain to timeline of recovery, specific activities, and limitations.

Background: Reverse total shoulder arthroplasty (rTSA) demonstrates favorable long-term data and has outpaced anatomic total shoulder arthroplasty and hemiarthroplasty as the most-performed shoulder arthroplasty procedure. As indications and outcomes continue to favor rTSA, patients may turn to the internet as an efficient modality to answer various questions or concerns. This study investigates online patient questions pertaining to rTSA and the quality of the websites providing information.

Cement-within-cement technique in revision reverse total shoulder arthroplasty: complications, reoperations, and revision rates at 5-year mean follow-up.

Background: Revision reverse total shoulder arthroplasty (rTSA) of a previously cemented humeral component is challenging. In hip arthroplasty, the cement-within-cement (CwC) technique has been well described as an effective option. However, for shoulder arthroplasty there remains a paucity of data investigating this technique.

Surgical management of lateral epicondylitis: a scoping review of published literature.

Background: Surgical intervention for lateral epicondylitis remains a controversial topic, with its purpose being debated. Recent guidelines have concluded no benefit from surgery when compared to conservative management.

Methods: An electronic database search of Ovid Medline via PubMed, EMBASE, and the Web of Science was performed to understand the published literature further.

Coracoid osteotomy approach for open free bone grafting of anterior glenoid defects.

The utilization of free bone grafts to reconstruct large anterior glenoid defects has increased. Distal tibia allograft is commonly used due to its lack of donor site morbidity, ability to restore large bony defects, and near anatomic osteoarticular restoration. However, the intact coracoid and conjoint tendon often impair adequate visualization and access to perform an anatomic reconstruction during open free bone graft reconstruction and often requires violation of the subscapularis tendon to gain exposure.

How does residency program reputation influence American shoulder and elbow surgeons fellowship match results?

Background: Postresidency training is becoming increasingly common among orthopedic surgeons, with shoulder and elbow surgery growing as a desired subspeciality. There is limited data evaluating how the reputation of an applicants' orthopedic residency influences the outcome of the shoulder and elbow fellowship match. The purpose of this study was to determine if applicants from residencies with better reputation have more favorable odds during the match process compared to applicants from residencies with a less prestigious reputation.
