Foot and ankle pain is frequently encountered in the PM&R clinic with various musculoskeletal and neuropathic pain generators. Local foot and ankle musculoskeletal pain generators can be divided based on their location into forefoot, midfoot, and hindfoot/ankle pathologies. Posterior tibialis tendon dysfunction is one of the most common causes of t...

The etiology for groin pain is diverse, including osteoarthritis, inflammatory arthropathy, impingement syndrome, iliopsoas tendinopathy, bursitis, labral tears, neuropathy, and others. Femoroacetabular impingement syndrome is an increasingly recognized cause of groin pain among active young adults, as illustrated in this case, and is secondary to...

Hand and wrist pain can be explained by musculoskeletal pathologies and neuropathic pathologies that can be further classified based on location, characteristics, and others. Differential diagnoses formulated by focused history and physical examination can be confirmed by imaging studies, serological tests, and electrodiagnosis. Most hand and wrist...

The common causes of shoulder pain include shoulder impingement syndrome, rotator cuff tendon pathologies, adhesive capsulitis, arthropathy involving acromioclavicular and glenohumeral joints, and others.

Description Physical inactivity (PI), defined as not meeting guidelines for physical activity beyond baseline daily living activities, is common among older adults (age 65 and older) and contributes to increased morbidity, increased mortality and increased health care spending. Understanding the clinical impact of PI on common medical conditions am...

Description Low back pain (LBP) is frequently encountered in outpatient clinics and affects individual patients and society in general with decreased physical function, quality of life, disability, and/or economic burden. Although most acute LBP resolves on its own, recurrent and chronic LBP is a common reason for outpatient clinic visits. This rev...

This study aimed to analyze the trends of opioid use disorders, cannabis use disorders, and palliative care among hospitalized patients with gastrointestinal cancer and to identify their associated factors. We analyzed the National Inpatient Sample data from 2005 to 2014 and included hospitalized patients with gastrointestinal cancers. The trends o...

Knee osteoarthritis (KOA) and chronic low back pain (CLBP) are common and often coexist. There are limited studies on the impact of coexisting musculoskeletal disorders on gait parameters and its association with self-assessed functional outcome. This study compared gait parameters, self-assessed functional outcome measurements, and quality of life...

Though overall death from opioid overdose are increasing in the United States, the death rate in some states and population groups is stabilizing or even decreasing. Several states have enacted a Naloxone Accessibility Laws to increase naloxone availability as an opioid antidote. The extent to which these laws permit layperson distribution and poss...

Objective To investigate trends and associated factors of utilization of hospital palliative care among patients with systemic lupus erythematosus (SLE) and analyze its impact on length of hospital stay, hospital charges, and in-hospital mortality. Methods Using the 2005-2014 National Inpatient Sample in the United States, the compound annual grow...

Design: Data of 172 patients wh...

Pyogenic infection of the spinal column is a relatively rare condition. Spondylodiscitis is characterized by infection of the intervertebral disk and the adjacent vertebrae. Diagnosis is often delayed because the symptoms are often nonspecific and also because of the high incidence of nonspecific low back pain in the general population. We report t...

Jumper’s knee is tendinopathy of the quadriceps or patellar tendon, which occurs due to overuse from repetitive jumping or running. Patients present with anterior knee pain and difficulty extending the knee due to pain. There is tenderness to palpation at the superior patellar pole in quadriceps tendinopathy and tenderness at the inferior patellar...

Rotator cuff tendinopathy is considered to be the most common cause of shoulder pain. It often results from impingement between the coracoacromial arch and the humeral head, also known as shoulder impingement syndrome. If not treated properly, it can progress to rotator cuff tear. Rotator cuff tendinopathy presents as anterolateral shoulder pain th...

Background The lateral retinacular nerve (LRN) is a branch of the superior lateral genicular nerve (SLGN) and is believed to contribute to anterolateral knee pain. The precise anatomical pathway of the LRN, however, has not been demonstrated as it relates to the performance of targeted nerve block procedures. Objective To describe the anatomical l...
