Hip Muscle Strength Predicts Non-contact ACL Injury in Male and Female Athlet...Rachel Straub
Background: Prospective studies have reported that abnormal movement patterns at the trunk, hip, and knee are associated with non-contact ACL injuries. Impaired hip strength may underlie these abnormal movement patterns, suggesting that diminished hip strength may increase the risk of non-contact ACL injury.
Purpose: To determine if baseline hip strength predicts future non-contact ACL injury in athletes.
Study Design: Prospective cohort study.
Methods: Prior to the start of the competitive season, isometric hip strength (external rotator and abductor) was measured bilaterally using a hand-held dynamometer in 501 competitive athletes (138 females and 363 males) participating in various sports. During the sport seasons, ACL injury status was recorded, and injured athletes were further classified based on the mechanism of injury (non-contact vs. contact). Postseason, logistic regression was used to determine whether baseline hip strength predicted future non-contact ACL injury. Receiver operating characteristic (ROC) curves were constructed independently for each strength measure to determine the clinical cut-off value to distinguish between a high-risk and low-risk outcome.
Results: A total of 15 non-contact ACL injuries were confirmed (6 female, 9 male), for an overall annual incidence of 3.0% (2.5% for males and 4.3% for females). Baseline hip strength measures (external rotator and abductor) were significantly lower in injured athletes compared to non-injured athletes (p = 0.003 and p < 0.001, respectively). Separate logistic regression models indicated impaired hip strength increased future injury risk [external rotator: OR = 1.23 (95% CI: 1.08, 1.39), p = 0.001; abductor: OR = 1.12 (95% CI: 1.05, 1.20), p = 0.001]. Clinical cutoffs to define high risk were established as external rotator strength ≤ 20.3% body weight (BW) or abductor strength ≤ 35.4% BW.
Conclusion: Measures of preseason isometric hip abductor and external rotator strength independently predicted future non-contact ACL injury status in competitive athletes. Our data suggest that screening procedures to assess ACL injury risk should include an assessment of isometric hip abductor and/or external rotator strength.
Describe about the chief complaints , gait assessment, special test and local examination of hip joint.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

transverse process
• Prevents rotation
16. THE LUMBAR FACETS
• Vary from the sagittal disposition at the first
and second, to almost coronal in the lower
• Facet tropism is when the facet on one side
is in the sagittal plane and the other is in the
coronal plane, which adds to rotational
stress
• This change may occur in the lower thoracic
vertebrae
17. PARS INTERARTICULARIS

22. ANTERIOR LONGITUDINAL LIGAMENT
• Attached mainly to the bodies
• This ligament helps to prevent us from leaning too far
back (hyperextension)
23. POSTERIOR LONGITUDINAL LIGAMENT

nucleus
• Weakest portion is the postero-lateral
and posterior
• Periphery has a nerve supply
31. NUCLEUS PULPOSUS
• Gelatinous, hydrophilic, proteoglycan gel in
collagen matrix
• Lies posterior in the disc
• There are no nerve endings in a mature disc
• Nerve endings are found in the posterior longitudinal ligament and the dura
• Nutrition of the disc is by diffusion via the central 40% of the cartilaginous end
plate
• The discs are thicker in the cervical and lumbar sections of the vertebral
column
• Where there is more movement. The largest disc is between L5 S1
32. NUCLEUS PULPOSUS
• Hydration of the annulus and nucleus is
proportional to the applied compressional
stress
• In vivo, there is a loss of 1 cm standing
height over the course of the day
• A disc loaded in vitro for four hours by
100% body weight will lose 6% of the
fluid from the nucleus and 13% from the
annulus
• May be due to end plate fracture
• There is more rotational stress in the posterior part of the disc
33. NUCLEUS PULPOSUS
• The position of the spine determines
where the compressional forces are
greatest
• The posterior longitudinal ligament is
thin and expanded at the level of the
disc
• High compressional loading at
L4,L5,S1 may be due to end plate
fracture and not to rupture of the annulus
• End plate failure is a possible precursor of disc degeneration
35. END-PLATE MECHANICS
• Functionally, the vertebral end-plate
displays characteristics of a trampoline
• With the sub-end-plate trabecular
bone acting as springs to sustain
and dissipate axial load
• Despite the thinness of the vertebral
end-plate
• The hydraulic nature of marrow and
blood vessels within the vertebral body,
act to dampen axial loads, unless the
local point pressure is too high
36. END-PLATE MECHANICS
• End-plate lesions can be induced experimentally
before a disc will prolapse through the anulus,
suggesting a protective mechanism over annular
injury and potentially cord or root compression
• Excessive loads may result in perforation of the
end-plate, usually in the region of the nucleus and
often in the path of the developmental notchord
38. FACET JOINTS

• Lower joints in coronal plane
• Synovial plane joints
• Meniscoid structures
• Synovial membrane some contain

The late natural history the thoracic kyphosis is for progressive deformation:
This deformation occurs within the vertebral bodies in women with a greater contribution from disc degeneration in males.[Goh et al 1999]
Those sports that predispose the individual to hyper-kyphosis during the adolescent years and beyond, should be studied to determine the association between the structural deformation and back pain.
[[Those of us destined to keyboard activity will identify with the evolutionary trend depicted above]]
As can be seen on the left, the vertebral end-plate is a tenuous cartilaginous membrane which from direct measurement is approximately 0.5mm thick, connected to trabecular bone within the cortical shell.
Lesions of the end-plate arising from sporting activities are reported to be frequent. Typical aetiology involves dynamic compressive axial loads, common in landing sports: eg: gymnastics
Discal material is extruded through the end-plate into the vertebral body. At the time of injury, the lesion may be painful due to the inflammatory response to the lesion. It has been postulated that such injury predisposes the disc to early degenerative change [Roberts et al, 1997 European Spine Journal 6: 387]
The late stage of healing involves sclerosis of bone around the site of injury, demonstrated on the right [arrow] form a CT at T11-12
The notochordal streak, as depicted by Schmorl & Junghanns from their classic text, showing a foetal specimen [left] and the progressive apoptosis of these cells during maturation and differentiation of the disc and vertebral body.
Typically, Schmorl’s nodes occur close to this site, suggesting both a functional and genetic predisposition to compressive load failure of the end-plates in some individuals.
In a recent CT study, 42 patients suspected of disc and facet joint pain were rotated within the CT scanner prior to scanning. They were fixed into this position for both right and left side scans which were compared with their neutral [conventional] scan images.
Very slight separation of the facet joints occurred at most levels and particularly where the anatomical alignment was mostly coronal [usually the lowest segments].
Joints with a more sagittal alignment, typically the upper lumbar spine, appeared to offer greater resistance to torsion.
Spine injuries can occur through overuse, overload, trauma or a combination of these events.
Injuries may occur to any component of the mobile segment: disc, vertebral bodies or facet joints, however disc and end-plate lesions are the most commonly affected.
The reported statistics for back pain according to Cooke & Lutz [2000] are:
Lifetime prevalence of back pain in the community = 60-80%
Back pain recurrence = 70-90%
Progression to chronic back pain = 5-10%
Back pain a common feature in most sports, particularly competitive contact sports.
Back pain is higher in young athletes compared with age matched controls and,
Back pain may occur in response to various conditions of load, fatigue and trauma

The incidence of end-plate lesions in sport participants varies, however, these may result from pre-existing anatomical abnormalities.
In the case of Scheuermann’s disease, there can be multiple end-plate lesions over many segments.
According to Sorenson, the characteristics of this disease involve four or more segments with lesions of the end-plates, and corresponding vertebral wedging.
Accentuated kyphosis and a painful thoraolumbar spine are the main clinical features.
AFL is a dynamic game that involves various types of play and physical encounters. Injuries are common, predominantly to the knee [ACL], hamstring and groin regions.
In a major survey of AFL injuries undertaken by Drs Seward & Orchard, identified a recurrence rate of 32% for injuries to the neck, back, and ribs.
