Article Synopsis
- The study investigates how surgeons treat massive rotator cuff tears, focusing on the use of superior capsule reconstruction (SCR) techniques and preferences.
- A questionnaire sent to orthopedic surgeons revealed preferred methods for rotator cuff repair, such as preserving the long head biceps tendon, using solid threaded anchors, and performing side-to-side repairs.
- The results indicate a lack of consensus on techniques and highlights the need for further research to establish best practice guidelines in managing these injuries.
Article Synopsis
- - Failure of rotator cuff repair can have serious consequences, and understanding the biology of the tendon insertion sites is crucial for improving outcomes.
- - Quality of the torn tendon plays a significant role in repair success, and augmentation techniques, including allografts, xenografts, and synthetics, can be beneficial for long-term healing.
- - This study focuses on a specific surgical technique that uses the patient's own coracoacromial ligament tissue to enhance the repair of the supraspinatus tendon during arthroscopy.
Article Synopsis
- ACL tears in the NBA are highly impactful injuries, leading to a cumulative economic loss of $99 million from 2000 to 2015, with an average cost of recovery at $2.9 million per player.
- The study found that players with lower preinjury salaries had significantly worse outcomes, including a lower return-to-play rate (63%) and decreased performance ratings after recovery compared to their All-Star counterparts.
- Overall, while 91% of players returned to play post-surgery, their performance metrics and longevity in the league often decreased, highlighting the long-term consequences of ACL injuries in professional basketball.
Article Synopsis
- - The COVID-19 pandemic led to an NBA suspension in 2020, and this study is the first to investigate its effects on player performance after recovery and return to the game.
- - Researchers compared NBA players' statistics during the 2019-2020 season and in the NBA bubble, finding those who recovered from COVID-19 played fewer minutes and had a slight decrease in various performance metrics, although some were not significant.
- - The study concluded that despite playing less in the bubble, the performance of recovered players was similar to their pre-COVID levels, with the exception of increased free throw accuracy.
Article Synopsis
- This study assessed how effective fondaparinux is in preventing venous thromboembolism (VTE) in high-risk patients after elective lumbar spine surgery.
- Researchers compared patients who received fondaparinux starting on the second day after surgery with those who did not receive it, focusing on outcomes like deep vein thrombosis (DVT) and pulmonary embolism (PE).
- Results showed fewer DVT cases in the fondaparinux group (0%) compared to the control group (2.9%), along with a favorable complication profile, although the study's retrospective nature limits strong conclusions.
Article Synopsis
- The study investigates how rabbit annulus fibrosus (AF) cells produce neuropeptide Y (NPY) when subjected to mechanical and inflammatory stress, with the aim of understanding its role in intervertebral disc health.
- Researchers exposed lumbar AF cells from young rabbits to different levels of tensile stress and inflammatory markers, finding that inflammatory conditions significantly increased NPY expression, while mechanical strain alone had minimal effect.
- The presence of NPY receptor-type 1 (NPY-1R) in rabbit AF cells was confirmed, suggesting that increased NPY production in response to stress could be linked to intervertebral disc degeneration and associated low back pain.
Evaluation and Treatment of Borderline Dysplasia: Moving Beyond the Lateral Center Edge Angle.
Curr Rev Musculoskelet Med
February 2020
Article Synopsis
- The manuscript aims to clarify the features of borderline acetabular dysplasia and analyze current methods for diagnosis and treatment options.
- Acetabular dysplasia is a significant contributor to hip pain due to inadequate coverage of the femoral head, with the lateral center edge angle (LCEA) used for classification—normal (above 25°) and pathological (below 20°).
- Borderline dysplasia is marked by LCEA values between 20 and 25, and relying solely on this measurement to assess severity can lead to incorrect interpretations; comprehensive evaluations of mild undercoverage are needed for better future studies comparing treatment methods.
: Post-operative day (POD) 0 physical therapy (PT) after total knee arthroplasty (TKA) has been associated with improved outcomes such as shorter hospital length of stay (LOS), though patient performance is variable. The purpose of this study was to evaluate PT performance and determine whether this affected LOS or discharge to home.: Retrospective review including 412 patients who underwent TKA over 1 year.
View Article and Find Full Text PDFAcute and chronic whiplash-associated disorders pose a significant healthcare burden due to chronic pain, which is associated with upper cervical instability resulting from ligamentous injury. No standard measure exists for diagnosing alar ligament injury and imaging findings vary widely. Multiple physical examination maneuvers are used to diagnose alar ligament injury including the C2 Spinous Kick, Flexion-Rotation, and Bending-Rotation tests.
View Article and Find Full Text PDFBackground: The distal biceps tendon externally rotates from proximal to distal before inserting onto the radius. Our hypothesis is that an externally rotated (anatomic) repair would re-create native supination moment arm and flexion force, whereas an internally rotated (nonanatomic) repair would result in reduced force transmission.
Methods: The mechanical tests performed in this study measured isometric moment arms and elbow flexion force using a validated elbow simulator as previously published.
Introduction: Treatment of early-onset scoliosis (EOS) can be difficult. Various forms of growing rods exist to correct deformity while delaying definitive spinal fusion. The disadvantage of traditional growing rods is need for repeated surgical lengthening procedures.

- The study is a retrospective cohort design aimed at comparing a new two-step algorithm for recommending CTA in cervical spine fracture cases with existing guidelines from the American College of Surgeons and Denver Criteria.
- It evaluated the ability of these screening criteria to accurately identify blunt cerebrovascular injuries (BCVI) and strokes in patients admitted to a trauma center over a four-year period.
- The novel algorithm detected similar rates of BCVI and strokes as the established criteria but significantly reduced the number of unnecessary scans needed, suggesting it could be a more efficient method for identifying at-risk patients.*
Early-onset scoliosis (EOS) remains a challenging condition for which current nonfusion surgeries require iterative lengthening surgeries. A growing rod with sliding pedicle screw system (GRSPSS) was developed to treat spinal deformities without repeated operative lengthening. This study was performed to evaluate whether GRSPSS had similar stability as a conventional pedicle screw system to maintain deformity correction.

Objectives: Compare the destabilizing effects of anterior discectomy to posterior spinal releases.
Summary Of Background Data: Posterior release and pedicle screw fixation has become the accepted form of treatment for lumbar and thoracolumbar pediatric scoliotic spinal deformity.
Article Synopsis
- The manuscript reviews the history, techniques, and methodology of quantitative pivot shift investigations and evaluates its clinical importance in managing ACL injuries and associated issues like the ALC.
- It highlights that the pivot shift test is crucial for diagnosing rotatory instability from ACL tears, noting that it can be influenced by other injuries or anatomical factors.
- The presence of a pivot shift after surgery leads to worse outcomes, indicating the need for more research on effective management strategies for ALC along with ACL injuries.
Tissue engineering approaches to treatment of intervertebral disc degeneration (IDD) represent a novel avenue of addressing the biologic basis of this disease. However, such approaches remain limited by their invasive nature and disruption to the annular fibrosis (AF). This study sought to explore a new minimally-invasive tissue-engineering approach utilizing an injection of a photopolymerizable biogel scaffold seeded with mesenchymal stem cells (MSCs) directly into the nucleus pulposus (NP).
View Article and Find Full Text PDFFractures of the odontoid present frequently in spinal trauma, and Type II odontoid fractures, occurring at the junction of the odontoid process and C2 vertebrae, represent the bulk of all traumatic odontoid fractures. It is currently unclear what soft-tissue stabilizers contribute to upper cervical motion in the setting of a Type II odontoid fracture, and evaluation of how concomitant injury contributes to cervical stability may inform surgical decision-making as well as allow for the creation of future, accurate, biomechanical models of the upper cervical spine. The objective of the current study was to determine the contribution of soft-tissue stabilizers in the upper cervical spine following a Type II odontoid fracture.

- Postoperative C5 palsy is a common complication after cervical surgeries, especially posterior laminectomy and fusions, and there is currently no known medication to prevent it.
- This study aims to evaluate whether using prophylactic dexamethasone (DEX) before and during surgery can lower the occurrence of C5 palsy in patients undergoing multilevel posterior cervical laminectomy and fusion.
- The researchers reviewed 189 patients who received DEX during their surgeries from 2012 to 2017 to compare the rate of C5 palsy with previous rates before DEX was used.
Background Context: Non-steroidal anti-inflammatory drugs (NSAIDs) are a widely used treatment for low back pain (LBP). Literature on NSAID use in articular cartilage has shown detrimental effects; however, minimal data exist to detail the effects of NSAIDs in intervertebral disc degeneration (IDD). As IDD is a major cause of LBP, we explored the effects of indomethacin, a commonly used NSAID, on disc matrix homeostasis in an animal model of IDD.

- The study aimed to evaluate outcomes for patients with Charcot neuroarthropathy (CN), focusing on whether patients with Charcot-related foot wounds had lower limb salvage rates compared to those without wounds.
- A total of 245 patients (280 feet) were analyzed, revealing that 72.1% required surgery, with 10% of those surgically treated ultimately needing amputations.
- The findings showed that patients with Charcot-related foot wounds had a significantly higher amputation rate (21.3%) versus those without wounds (4.5%), indicating that wounds negatively impact limb salvage outcomes.
Article Synopsis
- Ankle fractures in diabetic patients, especially those with peripheral neuropathy, pose significant treatment challenges, particularly when initial surgeries fail, leading to unclear treatment options for limb salvage.
- A study of 17 patients who had bimalleolar ankle fractures and unsuccessful initial operations revealed that various interventions, such as revision open reduction internal fixation (ORIF), closed reduction external fixation (CREF), and ankle joint fusion, had an overall limb salvage rate of 82.3%.
- Successful limb salvage often resulted in clinically fused ankle joints, but the study highlights that achieving functional recovery is difficult and that CREF may be the most effective approach in cases with infection or bone quality issues.
Article Synopsis
- Posterior tibialis tendon dysfunction (PTTD) is linked to flatfoot deformity in adults and is often treated with a tendon transfer from the flexor digitorum longus to various attachment sites.
- A study using robotic gait simulation assessed three transfer locations (navicular, medial cuneiform, and the degraded tendon site) on flatfoot models to evaluate their kinetic and kinematic effects.
- Results showed that while there were decreases in peak plantar pressure at certain points, all surgical procedures performed similarly with minimal differences compared to the flatfoot condition.
