Chronic exertional compartment syndrome of the forearm diagnosed in a wider spectrum of patients and not seldom with a history of the same diagnosis in the lower legs.

Purpose: To identify patient characteristics associated with forearm chronic exertional compartment syndrome (CECS) and to demonstrate the distribution of intramuscular pressure (IMP) values at 1 min postexercise in a cohort of patients with exercise-induced forearm pain.

Methods: A consecutive series of 99 patients seeking orthopaedic consultation for chronic exertional forearm pain underwent IMP measurements between 2010 and 2023. The diagnosis of CECS was confirmed ( = 34) or ruled out ( = 65) based on the patient's history, clinical examination and IMP measurements.

MRI evaluation of foraminal changes in the cervical spine with assistance of a novel compression device.

Standard supine Magnetic Resonance Imaging (MRI) does not acquire images in a position where most patients with intermittent arm radiculopathy have symptoms. The aim of this study was to test the feasibility of a new compression device and to evaluate image quality and foraminal properties during a Spurling test under MRI acquisition. Ten asymptomatic individuals were included in the study (6 men and 4 women; age range 27 to 55 years).

Intramuscular Pressure and Patient-Reported Outcomes in Patients Surgically Treated for Anterior Chronic Exertional Compartment Syndrome.

Background: Chronic exertional compartment syndrome (CECS) causes exercise-induced leg pain. The diagnosis is confirmed by intramuscular pressure (IMP) measurements. Fasciotomy has been demonstrated to be a successful treatment for CECS; however, few studies have examined postoperative IMP and long-term outcomes.

Cervical spine and muscle adaptation after spaceflight and relationship to herniation risk: protocol from 'Cervical in Space' trial.

Background: Astronauts have a higher risk of cervical intervertebral disc herniation. Several mechanisms have been attributed as causative factors for this increased risk. However, most of the previous studies have examined potential causal factors for lumbar intervertebral disc herniation only.

The effect of gender on intramuscular pressure in patients with chronic exertional compartment syndrome of the lower leg.

This study aimed to compare intramuscular pressure (IMP) in all four compartments of the lower leg between men and women in patients with suspected chronic exertional compartment syndrome (CECS), and to assess possible effects of gender in relation to covariation factors. A consecutive series of patients with exertional leg pain (n = 962, median age 27 years, 56.2% women) underwent IMP measurements between 2009 and 2019.

Significantly lower intramuscular pressure in the posterior and lateral compartments compared with the anterior compartment suggests alterations of the diagnostic criteria for chronic exertional compartment syndrome in the lower leg.

Purpose: To investigate distributions and identify possible differences in intramuscular pressure (IMP) values at 1 min post-exercise between the four muscle compartments of the lower leg, in patients with exertional leg pain with or without chronic exertional compartment syndrome (CECS).

Methods: A consecutive series of patients seeking orthopaedic consultation for exertional leg pain underwent IMP measurements between 2009 and 2018. The diagnosis of CECS was confirmed (n = 442) or ruled out (n = 422), based on the patient's history, clinical examination, and IMP measurements.

Effects of Exercise Compression Stockings on Anterior Muscle Compartment Pressure and Oxygenation During Running: A Randomized Crossover Trial Conducted in Healthy Recreational Runners.

Background: Exercise compression garments have increased in popularity among athletes at all levels during the last 10 years. However, the scientific grounds for this are unclear. The purpose of the present study was to examine the effect of wearing exercise compression stockings (CS) on the anterior compartment pressure, oxygenation of the tibialis anterior muscle, and early blood biomarkers change for muscle damage during a 10-km treadmill run in healthy subjects.

Patient pain drawing is a valuable instrument in assessing the causes of exercise-induced leg pain.

Aim: We validated patientpain drawing (PPD) in establishing the diagnosis of chronic anterior compartment syndrome (CACS) in patients with exercise-induced leg pain.

Methods: The study comprised 477 consecutive patients, all suspected of having CACS. The diagnosis was based on the patient's history, a thorough clinical examination and measurements of intramuscular pressure (IMP) following an exercise test.

Changes in Muscle Oxygen Saturation Have Low Sensitivity in Diagnosing Chronic Anterior Compartment Syndrome of the Leg.

Background: Near-infrared spectroscopy measures muscle oxygen saturation (StO2) in the skeletal muscle and has been proposed as a noninvasive tool for diagnosing chronic anterior compartment syndrome (CACS). The purpose of this study was to investigate the diagnostic value of changes in StO2 during and after exercise in patients with CACS.

Methods: The study comprised 159 consecutive patients with exercise-induced leg pain.

Detection of changes in muscle oxygen saturation in the human leg: a comparison of two near-infrared spectroscopy devices.

The purpose of this study was first to evaluate the near infrared spectroscopy (NIRS) device, INVOS 4100 as a method of measuring exercise and arterial occlusion induced muscle ischemia in human leg, by comparison with InSpectra tissue spectrometer Model 325, and secondly to determine the influence of skin and subcutaneous thickness on the NIRS measurements. Twenty healthy subjects (43 ± 8 years) volunteered for the study. Tissue oxygen saturation (StO2) in the anterior tibial muscle was measured simultaneously with InSpectra Model 325 in one leg and INVOS 4100 in the contralateral leg during an exercise test until muscle exhaustion and arterial occlusion with and without exercise.

The magnitude of intramuscular deoxygenation during exercise is an unreliable measure to diagnose the cause of leg pain.

We measured intramuscular oxygenation in the anterior tibial muscle of 176 patients with exercise-induced leg pain by noninvasive near-infrared spectroscopy before, during, and after an exercise test that elicited the symptoms. Clinical investigation was performed after each test. Intramuscular pressure was measured in patients with nonconclusive findings.
