Compartment Syndrome and Fasciotomy
Compartment syndrome and fasciotomy The aim of this information sheet is to help answer some of the questions you may have about having a fasciotomy for compartment syndrome. If you have any questions or concerns, please do not hesitate to speak to a doctor or nurse caring for you. What is compartment syndrome? Compartment syndrome occurs due to increased pressure within a confined space or compartment in the calf or thigh. This could be in just one leg or in both legs. If untreated, it can restrict the blood supply to muscles in the affected compartment and can result in necrosis (death) of the muscles. Nerves are also damaged from this pressure. This can result in loss of sensation in the skin and paralysis of the muscles they supply. Rapid diagnosis and treatment to relieve the pressure can lead to complete recovery of the affected muscle. What causes compartment syndrome? If the blood supply to your leg or legs has been interrupted, when blood flow is restored the muscles in the leg/legs swell causing compartment syndrome. If you have been admitted to hospital as an emergency with poor blood supply to the leg, this can happen when the blood flow is restored. The initial injury usually causes swelling of the muscle and tissues within the fascial compartment of the limb. This causes the pressure within the compartment to rise. As time progresses, and as the degree of pressure increases, blood flow to the muscles reduces. This lack of blood flow means that oxygen is not delivered effectively to the muscles and nerve damage begins to occur.

Thigh Muscles
Lecture 14 THIGH MUSCLES ANTERIOR and Medial COMPARTMENT BY Dr Farooq Khan Aurakzai PMC Dated: 03.08.2021 INTRODUCTION What are the muscle compartments? The limbs can be divided into segments. If these segments are cut transversely, it is apparent that they are divided into multiple sections. These are called fascial compartments, and are formed by tough connective tissue septa. Compartments are groupings of muscles, nerves, and blood vessels in your arms and legs. INTRODUCTION to the thigh Muscles The musculature of the thigh can be split into three sections by intermuscular septas in to; Anterior compartment Medial compartment and Posterior compartment. Each compartment has a distinct innervation and function. • The Anterior compartment muscle are the flexors of hip and extensors of knee. • The Medial compartment muscle are adductors of thigh. • The Posterior compartment muscle are extensor of hip and flexors of knee. Anterior Muscles of thigh The muscles in the anterior compartment of the thigh are innervated by the femoral nerve (L2-L4), and as a general rule, act to extend the leg at the knee joint. There are three major muscles in the anterior thigh –: • The pectineus, • Sartorius and • Quadriceps femoris. In addition to these, the end of the iliopsoas muscle passes into the anterior compartment. ANTERIOR COMPARTMENT MUSCLE 1. SARTORIUS Is a long strap like and the most superficial muscle of the thigh descends obliquely Is making one of the tendon of Pes anserinus . In the upper 1/3 of the thigh the med margin of it makes the lat margin of Femoral triangle. Origin: Anterior superior iliac spine.

Chronic Exertional Compartment Syndrome of the Leg in the Military
Chronic Exertional Compartment Syndrome of the Leg in the Military a a,b,c, John C. Dunn, MD , Brian R. Waterman, MD * KEYWORDS Chronic exertional compartment syndrome Intracompartmental pressure Paresthesia KEY POINTS Chronic exertional compartment syndrome affects young athletic individuals, especially those in active duty military service. Nonoperative treatment may benefit low-demand patients; however, in an athletic cohort surgical decompression must be considered in a patient that fails conservative management. Although good surgical outcomes have been reported by tertiary referral centers, return to duty rates in the military are poor, with only 55% of patients experiencing complete res- olution of symptoms. Patient education, activity modification, and gait retraining may be beneficial to optimize symptomatic relief. INTRODUCTION Activity-related lower extremity pain is common among athletes and other active patient populations. Along with other overuse conditions, chronic exertional compart- ment syndrome (CECS) may contribute significantly to the development of effort- dependent leg symptoms. One of the earliest descriptions of CECS occurred during the British expedition to the South Pole in 1912, in which Edward Wilson described anterior leg swelling and pain during long treks in the Arctic.1 Subsequent historical records have also emphasized the prevalence of CECS in military cohorts,2,3 earning the appellation “march gangrene.”4 Conflict of Interest: None.

Compartment Syndrome
Ministry of Defence Synopsis of Causation Compartment Syndrome Author: Dr Tony Fisher, Medical Author, Medical Text, Edinburgh Validator: Mr Fares S Haddad, University College Hospital London September 2008 Disclaimer This synopsis has been completed by medical practitioners. It is based on a literature search at the standard of a textbook of medicine and generalist review articles. It is not intended to be a meta- analysis of the literature on the condition specified. Every effort has been taken to ensure that the information contained in the synopsis is accurate and consistent with current knowledge and practice and to do this the synopsis has been subject to an external validation process by consultants in a relevant specialty nominated by the Royal Society of Medicine. The Ministry of Defence accepts full responsibility for the contents of this synopsis, and for any claims for loss, damage or injury arising from the use of this synopsis by the Ministry of Defence. 2 1. Definition 1.1 Acute compartment syndrome (ACS) is a condition which occurs when increased tissue pressure within a myofascial compartment compromises the vascular supply and the function of structures within that space. 1.2 The increase of hydrostatic and osmotic pressure in the anatomical compartment leads to a decrease in arterial inflow and impairment of perfusion. A cascade of injury follows, with disruption of the metabolic processes of the muscle, cytolysis and the release of osmotically active cell contents. This results in further perfusion of fluid from capillaries and added pressure within the compartment, compromising the function of structures such as blood vessels and nerves and the muscle units they supply.

Compartment Syndrome
Compartment Syndrome Chapter 34 Compartment Syndrome Introduction Compartment syndrome may occur with an injury to any fascial compartment. The fascial defect caused by the injury may not be adequate to fully decompress the compartment, and compartment syndrome may still occur. Mechanisms of injuries associated with compartment syndrome. o Open fractures. o Closed fractures. o Penetrating wounds. o Crush injuries. o Vascular injuries. o Injection injuries. o Infiltrated intravenous catheters. o Reperfusion following vascular repairs. o Burns/electrical shock. Early clinical diagnosis of compartment syndrome. o Pain out of proportion. o Pain with passive stretch. o Tense, swollen compartment. Late clinical diagnosis. o Paresthesia. o Pulselessness and pallor. o Paralysis. Measurement of compartment pressures: If available, compartment pressure monitors (including improvised use of arterial line transducers) may provide additional information, especially in obtunded patients. Compartment syndrome, however, remains a clinical diagnosis, and prophylactic fasciotomies are indicated in high energy 491 Emergency War Surgery injuries, especially if prolonged transport times are anticipated. o Diagnosis of compartment syndrome is made on clinical grounds, and the formal measurement of compartment pressures is generally not necessary. o Compartment pressure measurement can be considered in obtunded patients with questionable exam findings. Measurement threshold of ∆P < 30 mmHg (∆P = DBP- absolute compartment pressure) is an indication for fasciotomy. Consider prophylactic fasciotomy for: o Vascular repair/shunt and/or ligation independent of ischemia time. (See Chapter 25, Vascular Injuries.) o High index of suspicion injuries and limited capacity for serial examination. ♦ Intubated, comatose, sedated. ♦ Traumatic brain injury. ♦ Prolonged transport. Fasciotomy Technique Upper extremity. o Arm: The arm has two compartments: the anterior flexors (biceps, brachialis) and the posterior extensors (triceps).

Acute Traumatic Thoracolumbar Paraspinal Compartment Syndrome: Case Report
CASE REPORT J Neurosurg Spine 30:140–145, 2019 Acute traumatic thoracolumbar paraspinal compartment syndrome: case report Katharine D. Harper, MD,1 Dayna Phillips, MD,1 Joseph M. Lopez, MD,2 and Zeeshan Sardar, MD1 Departments of 1Orthopaedic Surgery and Sports Medicine and 2Trauma and Surgical Critical Care, Temple University Hospital, Philadelphia, Pennsylvania Although compartment syndrome can occur in any compartment in the body, it rarely occurs in the paraspinal muscula- ture and has therefore only been reported in a few case reports. Despite its rare occurrence, acute paraspinal compart- ment syndrome has been shown to occur secondary to reperfusion injury and traumatic and atraumatic causes. Diag- nosis can be based on clinical examination findings, MRI or CT studies, or through direct measurement of intramuscular pressures. Conservative management should only be used in the setting of chronic presentation. Operative decompres- sion via fasciotomy in cases of acute presentation may improve the patient’s symptoms and outcomes. When treating acute paraspinal compartment syndrome via surgical decompression, an important aspect is the anatomical consider- ation. Although grouped under one name, each paraspinal muscle is enclosed within its own fascial compartment, all of which must be addressed to achieve an adequate decompression. The authors present the case of a 43-year-old female patient who presented to the emergency department with increasing low-back and flank pain after a fall. Associated sensory deficits in a cutaneous distribution combined with imaging and clinical findings contributed to the diagnosis of acute traumatic paraspinal compartment syndrome. The authors discuss this case and describe their surgical technique for managing acute paraspinal compartment syndrome.

Abstract Objective: The aim of this retrospective study is to reveal the anatomical variations of the saphenous fascia and the relationship between vena saphena magna and saphenous fascia. Methods: 123 patients who had venous insuffiency symptoms were evaluated retrospectively. Gray scale ultrasonography (US) with colour Doppler and spectral analysis is used for detecting anatomy. The lower limb is divided into five Regions. In all Regions the anatomy of the saphenous fascia and the relationship between the fascia and saphenous vein (inside the fascia or outside the fascia) is detected. Results: Saphenous fascia is found in two different anatomical patterns: interrupted and continuous. The five Regions of the lower limb have different anatomical patterns of saphenous fascia. It was found that there was a significant relation between the uninterrupted formation of fascia and the presence of saphen vein in the saphenous fascia. Conclusion: We propose that vena saphena magna has two different anatomical patterns.
