Palmaris longus is a dispensable muscle with a long tendon However, this figure varies considerably in different ethnic which is very useful in reconstructive surgery. It is absent groups. A study by Thompson et al6 on 300 Caucasian 2.8 to 24% of the population depending on the race/ethnicity subjects found that palmaris longus was absent unilaterally in studied. Four hundred and fifty healthy subjects (equally 16%, and bilaterally in 9% of the study sample for an overall distributed among Malaysia’s 3 major ethnic groups) were prevalence of absence of 24%. Similarly, George7 noted on clinically examined for the presence or absence of palmaris 276 cadavers of European descent that its absence was 13% longus. This tendon was found to be absent unilaterally in unilaterally, 8.7% bilaterally for an overall absence of 15.2%. 6.4% of study subjects, and bilaterally in 2.9% of study Another cadaveric study by Vanderhooft8 in Seattle, USA participants.

  • Wrist Fracture – Advice Following Removal of Your Cast
    Wrist Fracture – advice following removal of your cast A plaster cast usually prevents a fracture from moving, but allows your fingers to move. The cast also reduces pain. What to expect It usually takes four to six weeks for new bone to form to heal your fracture. When the cast is removed most people find that their wrist is stiff, weak and uncomfortable to start with. It may also be prone to swelling and the skin dry or flaky, this is quite normal. It is normal to get some pain after your fracture. If you need painkillers you should take them as prescribed as this will allow you to do your exercises and use your wrist for light activities. You can ask a Pharmacist about over the counter painkillers. If your pain is severe, continuous or excessive you should contact your GP. The new bone gradually matures and becomes stronger over the next few months. It is likely to be tender and may hurt if you bang it. The muscles will be weak initially, but they should gradually build up as you start to use your hand and wrist. When can I start to use my hand and wrist? It is important to try and use your hand and wrist as normally as possible. Start with light activities like fastening buttons, washing your face, eating, turning the pages of books over etc. Build up as pain allows. Avoid lifting a kettle for 4 weeks If I have been given a Wrist splint You may have been given a wrist splint to wear.

  • Wrist Fracture
    Hand Conditions: WRIST FRACTURE A wrist fracture is a break in one or more of the bones in the wrist. The wrist is made up of the two bones in the forearm called the radius and the ulna. It also includes eight carpal bones. The carpal bones lie between the end of the forearm bones and the bases of the fi ngers. The most commonly fractured carpal bone is called the scaphoid or navicular bone. This fact sheet will focus on fractures of the carpal bones of the wrist. Causes A wrist fracture is caused by trauma to the bones in the wrist. Trauma may be caused by: • Falling on an outstretched arm • Direct blow to the wrist • Severe twist of the wrist Risk Factors Factors that increase your chance of developing a wrist fracture include: • Participating in contact sports, such as football or soccer • Participating in activities such as in-line skating, skateboarding, or bike riding • Participating in any activity which could cause you to fall on your outstretched hand • Violence or high-velocity trauma, such as an automobile accident Symptoms If you have any of these symptoms, do not assume they are due to a wrist fracture. Symptoms of a wrist fracture include. • Pain • Swelling and tenderness around the wrist • Bruising around the wrist • Limited range of wrist or thumb motion • Visible deformity in the wrist For more information visit us online at www.ptandme.com Hand Conditions: WRIST FRACTURE Diagnosis Your doctor will ask about your symptoms, physical activity, and how the injury occurred. The injured area will be examined.

  • Anatomic Variations in Relation to the Origin of the Musculocutaneous Nerve: Absence and Non-Perforation of the Coracobrachialis Muscle
    Int. J. Morphol., 36(2):425-429, 2018. Anatomic Variations in Relation to the Origin of the Musculocutaneous Nerve: Absence and Non-Perforation of the Coracobrachialis Muscle. Anatomical Study and Clinical Significance Variaciones Anatómicas en Relación al Origen del Nervio Musculocutáneo: Ausencia y no Perforación del Músculo Coracobraquial: Estudio Anatómico y Significado Clínico Daniel Raúl Ballesteros Larrotta1; Pedro Luis Forero Porras2 & Luis Ernesto Ballesteros Acuña1 BALLESTEROS, D. R.; FORERO, P. L. & BALLESTEROS, L. E. Anatomic variations in relation to the origin of the musculocutaneous nerve: Absence and non-perforation of the coracobrachialis muscle. Anatomical study and clinical significance. Int. J. Morphol., 36(2):425- 429, 2018. SUMMARY: The most frequent anatomic variations of the musculocutaneous nerve could be divided in two main groups: communicating branches with the median nerve and variations in relation to the origin, which in turn can be subdivided into absence of the nerve and non-perforation of the coracobrachialis muscle. Unusual clinical symptoms and/or unusual physical examination in patients with motor disorders, could be explained by anatomic variations of the musculocutaneous nerve. A total of 106 arms were evaluated, corresponding to 53 fresh male cadavers who were undergoing necropsy. The presence or absence of the musculocutaneous nerve was evaluated and whether it pierced the coracobrachialis muscle or not. The lengths of the motor branches and the distances from its origins to the coracoid process were measured. In 10 cases (9.5 %) an unusual origin pattern was observed, of which six (5.7 %) correspond to non-perforation of the coracobrachialis muscle and four (3.8 %) correspond to absence of the nerve.

  • Anatomical, Clinical, and Electrodiagnostic Features of Radial Neuropathies
    Anatomical, Clinical, and Electrodiagnostic Features of Radial Neuropathies a, b Leo H. Wang, MD, PhD *, Michael D. Weiss, MD KEYWORDS Radial Posterior interosseous Neuropathy Electrodiagnostic study KEY POINTS The radial nerve subserves the extensor compartment of the arm. Radial nerve lesions are common because of the length and winding course of the nerve. The radial nerve is in direct contact with bone at the midpoint and distal third of the humerus, and therefore most vulnerable to compression or contusion from fractures. Electrodiagnostic studies are useful to localize and characterize the injury as axonal or demyelinating. Radial neuropathies at the midhumeral shaft tend to have good prognosis. INTRODUCTION The radial nerve is the principal nerve in the upper extremity that subserves the extensor compartments of the arm. It has a long and winding course rendering it vulnerable to injury. Radial neuropathies are commonly a consequence of acute trau- matic injury and only rarely caused by entrapment in the absence of such an injury. This article reviews the anatomy of the radial nerve, common sites of injury and their presentation, and the electrodiagnostic approach to localizing the lesion. ANATOMY OF THE RADIAL NERVE Course of the Radial Nerve The radial nerve subserves the extensors of the arms and fingers and the sensory nerves of the extensor surface of the arm.1–3 Because it serves the sensory and motor Disclosures: Dr Wang has no relevant disclosures.

  • Unusual Cubital Fossa Anatomy – Case Report
    Anatomy Journal of Africa 2 (1): 80-83 (2013) Case Report UNUSUAL CUBITAL FOSSA ANATOMY – CASE REPORT Surekha D Shetty, Satheesha Nayak B, Naveen Kumar, Anitha Guru. Correspondence: Dr. Satheesha Nayak B, Department of Anatomy, Melaka Manipal Medical College (Manipal Campus), Manipal University, Madhav Nagar, Manipal, Karnataka State, India. 576104 Email: [email protected] SUMMARY The median nerve is known to show variations in its origin, course, relations and distribution. But in almost all cases it passes through the cubital fossa. We saw a cubital fossa without a median nerve. The median nerve had a normal course in the upper part of front of the arm but in the distal third of the arm it passed in front of the medial epicondyle of humerus, surrounded by fleshy fibres of pronator teres muscle. Its course and distribution in the forearm was normal. In the same limb, the fleshy fibres of the brachialis muscle directly continued into the forearm as brachioradialis, there being no fibrous septum separating the two muscles from each other. The close relationship of the nerve to the epicondyle might make it vulnerable in the fractures of the epicondyle. The muscle fibres surrounding the nerve might pull up on the nerve and result in altered sensory-motor functions of the hand. Since the brachialis and brachioradialis are two muscles supplied by two different nerves, this continuity of the muscles might result in compression/entrapment of the radial nerve in it. Key words: Median nerve, cubital fossa, brachialis, brachioradialis, entrapment INTRODUCTION The median nerve is the main content of and broad tendon which is inserted into the cubital fossa along with brachial artery and ulnar tuberosity and to a rough surface on the biceps brachii tendon.

  • Anatomy, Shoulder and Upper Limb, Arm Quadrangular Space
    NCBI Bookshelf. A service of the National Library of Medicine, National Institutes of Health. StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2018 Jan-. Anatomy, Shoulder and Upper Limb, Arm Quadrangular Space Authors Irfan A. Khan1; Matthew Varacallo2. Affiliations 1 Florida International University 2 Department of Orthopaedic Surgery, University of Kentucky School of Medicine Last Update: December 21, 2018. Introduction The quadrangular (or quadrilateral) space (QS) is named based on the shape of its anatomic boundaries. Located along the posterolateral shoulder, the QS serves as a passageway for the axillary nerve and posterior humeral circumflex artery (PHCA). Quadrangular (or quadrilateral) space syndrome (QSS) can occur secondary to various compressive pathologies. Although the incidence of such pathologies is rare, QSS has a known predilection for subgroups of athletic populations and can often suffer misdiagnosis or are clinically under-appreciated. Thus, clinicians should maintain a heightened clinical suspicion for QSS in patients aged 20-40 years of age presenting with a history of current contact or overhead athletic performance (e.g., baseball pitchers, swimmers, etc.), [1][2] or overhead laborers secondary to repetitive stress mechanics on the shoulder.[3] Structure and Function The QS has four anatomic borders; the teres minor superiorly, the inferior border is the teres major muscle, the medial boundary is the long head of the triceps brachii muscle, and the humeral surgical neck forms the lateral bound. The QS functions as a passageway for the axillary nerve, and the posterior humeral circumflex artery (PHCA).[3] The latter provides the primary (two-thirds) of the blood supply to the humeral head.[4] Blood Supply and Lymphatics The posterior humeral circumflex artery (PHCA) within the quadrangular space originates from the axillary artery, and within the QS, the PHCA divides into anterior and posterior branches.

Shane Tubbs3,4,5 · Michał Polguj2 Received: 27 May 2020 / Accepted: 7 July 2020 / Published online: 12 July 2020 © The Author(s) 2020 Abstract The subscapularis muscle is the largest muscle of the rotator cuf and its main function is internal rotation. It is morphologi- cally variable in both point of origin and insertion. The presence of an accessory subscapularis muscle can lead to brachial plexus neuropathy. This report presents a very rare accessory subscapularis muscle originating from two distinct bands on the subscapularis and teres major muscles. The insertion was divided among four tendons. The fourth tendon is bifurcated. One of these was connected to the tendon of the subscapularis muscle and the other three inserted into the base of the cora- coid process of the scapula. This anomalous muscle has the potential to entrap the nerves of the posterior cord such as the axillary, lower subscapular, and thoracodorsal nerves.
