The lameness rarely resolves completely following the block but can improve to greater than 80%.3 Flexion tests can be performed on the elbow by advancing the leg forward; this action simultaneously extends the shoulder joint.3,5 These flexion tests may be hard to interpret as some horses may resent this test and are negative for elbow disease. The overlying skin may either be closed or open resulting in local infection. Horses treated aggressively and early will have the best chance to prevent the onset of future osteoarthritis. Horses can have boots placed over the shoes to prevent the rubbing over the olecranon. As with every twist, also in case of shoulder twist, they are very painful and if the person is not capable to locate twisted area in anatomically correct position, one should seek Traumatology Orthopaedics specialist help. Fig 18.1 Complete and comminuted fracture of the olecranon. Horses with effusion in the elbow joint will typically have a positive response to flexion. Describe the shoulder joint under the 1,2 The humeral epicondyles articulate with the proximal aspect of the radius. Brachial plexus injury Although stronger locking plates are now available (5.5 broad), these can still be challenging fractures to internally stabilize due to secondary complications such as contralateral limb laminitis or implant infection. Anatomy Arthritis of elbow joint is inflammation process in the joint that is expressed with pain and limited movements. Abduction or adduction of the limb may provide a presumptive diagnosis; however without complete tearing the bone articulation between the humerus and the radius/ulna, the diagnosis may be difficult without imaging.3 Mild osteoarthritis of the elbow joint. During the post-operative period caring regimen for the elbow must be observed for a prolonged period of time (up to 8 weeks). Shoulder and elbow joint replacements are very successful. Furthermore, since scanning requires general anesthesia substantial risk is encountered during anesthetic recovery unless the fracture is repaired with internal fixation. If the fracture can be treated conservatively, the prognosis is good. The course of healing will depend upon the degree of damage, but can take upwards of six months to one year for complete healing. Surgical intervention is recommended when the medical and physiotherapist treatment is not successful, and then joint is freed from scar tissues thus restoring range of movements and preventing reason of the pain. Since these fractures are traumatic, there are no reported prevention strategies. The severity of lameness will depend upon the degree of displacement of the fracture.3,5,15 Complete, displaced fractures will result in a non-weight bearing lameness. Therapeutic strategies are aimed at decreasing the inflammation within the joint. Non-displaced and non-articular fractures are typically treated conservatively with rest, but should frequently be re-evaluated to ensure the fracture has not become displaced. In cases that are not treated aggressively, the long term prognosis is fair for soundness. Type 3: Fracture through the olecranon (non-articular) Complete resolution should not be expected, as osteoarthritis is a progressive condition and in this joint can be difficult to manage. Rotator cuff injury. View Shoulder and elbow joint.docx from HEALTH SCI 103 at Tunku Abdul Rahman University. Anti-inflammatory and analgesic medications are effective for treatment of arthrosis, as well as physical therapy treatments with purpose to activate blood circulation around the damaged bone. This is with a heavy bandage with a lateral splint that extends from the ground up to the withers and a caudal splint that extends from the ground to the olecranon. The resultant pressure leads to fluid accumulation underneath the skin. In separate cases, if it is not possible to prevent the problem, surgical intervention is applied with the aim to relieve or relax the elbow tendon. Rehabilitation depends on ultrasound appearance on recheck examinations. Laboratory examination Olecranon bursitis. Regenerative therapies such as bone marrow derived mesenchymal stem cells or platelet rich plasma may be beneficial in these cases. Septic elbow arthritis Infraspinatus bursitis Horses treated aggressively and early will have the best chance to prevent the onset of future osteoarthritis. 18.4). Osteoarthritis in the elbow joint is an uncommon cause of lameness in adult horses. Epidemiology The elbow joint is composed of the articulation between the distal humerus and the proximal radius and ulna. The ball is called the head of the humerus and the socket is called the glenoid (it's part of your shoulder blade, also known as the scapula). The swelling is usually freely movable. These fractures result from direct trauma to the olecranon from a kick or fall. Cytological differential cell counts will have a predominantly (>90%) mononuclear cell population. Etiology and pathophysiology Horses present with a variable degree of lameness, but it is typically severe in the acute stages. Type 5 and minimally displaced type 3 fractures can be treated conservatively successfully; whereas, other fracture configurations will typically require surgical treatment.1114. Through-and-through needle lavage can remove the source of infection and inflammatory mediators; however, advanced cases or those with gross contamination are better treated with arthroscopic lavage. The horse should be kept under stall confinement for at least a few months depending upon the degree of damage and then can be gradually re-introduced to handwalking. 18.2). Computed tomography would be more useful for surgical planning; however, this is still not an easily accessible area to image in the adult horse due to the current gantry size in most available scanners. The resultant lameness after this acute phase is dependent upon the degree of injury to the region if the elbow is destabilized.3 As there are no surgical procedures for treating these ligaments, healing is by second intention. Therapy Horses present with a swelling over the point of the elbow. Affected horses typically have a severe lameness that may result within 710 days following a traumatic wound to the area. As the edema subsides, a fluid pocket remains. Diagnostic confirmation Olecranon fractures typically result from a direct kick or falling injuries and so therefore are commonly associated with an open wound. Diagnosis can be made using ultrasound. Prognosis Radiographic examination of the elbow can be performed easily and can help evaluate for osteoarthritis, fractures, or osteochondrosis. The elbow joint is composed of the articulation between the distal humerus and the proximal radius and ulna. This entails strict stall confinement and cross-ties to prevent the horse from laying down. Ulnar/olecranon fractures Other causes of elbow lameness can be due to damage of the ligament and tendons in the region. The four instructed conditions were to tap on a keyswitch using the finger joint only (FO), the wrist joint only (WO), the elbow joint only (EO), and the shoulder joint only (SO). There is typically no lameness.20,21. Prognosis The shoulder is the most commonly dislocated joint in the body. Suprascapular nerve paralysis/Sweeny Most horses with olecranon fractures have a history of a direct kick from another horse or are injuries sustained when falling. If the fracture can be treated conservatively, the prognosis is good. Many of these horses become more comfortable with the splint applied. In horses with displaced fractures, attempts at weight bearing usually result in deviation of the limb and many will stand with their carpus and fetlock joints flexed and the toe dragging.
and polysulfated glycosaminoglycans can also be explored for treatment. The prognosis for soundness is excellent. Flexion or extension tests of the elbow may help localize the lameness to this region. Stress fractures may be visible radiographically, but may require nuclear scintigraphy in certain cases. The limb may be warm to the touch and attempts at flexing or extending the elbow joint will typically result in pain. The prognosis will depend upon the degree of contamination and the chronicity of infection. Ultrasound is the diagnostic method of choice for collateral ligament injuries. The course of healing will depend upon the degree of damage, but can take upwards of six months to one year for complete healing. Glenohumeral joint (Articulatio glenohumeralis) The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. Displaced and articular fractures warrant internal fixation to restore the joint surface. The bursa may be surgically resected if the above methods fail to resolve the condition. The best approach to diagnosing elbow disease is with intra-articular blocks with 2% mepivicaine (See Chapter 13). Diagnostic confirmation 18.5). During the surgery focal of inflammation is eliminated (resection); approximate location of the focal is determined already before the surgery by ultrasound examination. Lateral collateral ligament tears are more common than medial collateral tears and are relatively uncommon. Olecranon fractures typically result from a direct kick or falling injuries and so therefore are commonly associated with an open wound. Collateral ligament injury is rare as well as subluxations of the elbow joint. Horses typically present following a history of direct trauma or acute, severe lameness. 18.1) Once diagnosed, lifetime treatment is typically required. To help you get back to your daily activities as quickly as possible, we offer the most advanced surgical and nonsurgical treatments available. Together, the shoulder and elbow joints serve to position the hand for the performance of a task; without a hand, shoulder and elbow movements are almost useless. Displaced and articular fractures warrant internal fixation to restore the joint surface. Comparison to the contralateral limb is recommended. A wound over the radius may be present and is commonly on the medial aspect of the limb due to decreased soft tissue coverage in this area. Therapy Lateral collateral ligament tears are more common than medial collateral tears and are relatively uncommon. It is recommended to use anti-inflammatory medications, consult Traumatology Orthopaedics specialist, master and regularly perform complex of physiotherapy exercises. Therapies to treat osteoarthritis include: intra-articular corticosteroids, hyaluronan, polysulfated glycosaminoglycans or IRAP (see Chapter 23). The best approach to diagnosing elbow disease is with intra-articular blocks with 2% mepivicaine (See Chapter 13). Locking or Dynamic Compression Plates are typically used to repair these fractures. Computed tomography would be more useful for surgical planning; however, this is still not an easily accessible area to image in the adult horse due to the current gantry size in most available scanners. Diagnosis is by intra-articular anesthesia of the elbow joint. When the syndrome progresses; patient start experiencing pain at night, weakness and limited movements, difficulties to perform movements of arms behind the back, for example, zip the dress. Olecranon fractures are relatively common when compared to other fractures in adult horses. Diagnostic confirmation The prognosis is excellent for soundness, but may be difficult to resolve. This foal was suspected to have damage to the physis concurrently. Medial epicondylitis or golfers elbow is inflammation of the internal part of the joint where the bone is attached to the tendons of the muscles. Some people develop recurrent problems with either repeated dislocations or the feeling that the shoulder is about to dislocate. Prognosis is dependent upon the response to therapy, but cases with advanced radiographic changes will likely have a guarded prognosis for long term soundness. Systemic joint therapies such as NSAIDs, hyaluronan, and polysulfated glycosaminoglycans can also be explored for treatment. Therapy The cause of these collateral ligament tears is due to trauma either from a direct kick or the horse getting the limb lodged in a fence. Radial fractures in adult horses are relatively uncommon. The resultant pressure leads to fluid accumulation underneath the skin. On top of this ball and socket joint is another bone known as the acromion. In horses with displaced fractures, attempts at weight bearing usually result in deviation of the limb and many will stand with their carpus and fetlock joints flexed and the toe dragging. In case of rotator cuff injury problem is treated with anti-inflammatory medications, physiotherapy and hormonal steroid injections. The bursa is not a normal anatomic structure, but forms from the trauma. In post-operative period already starting from the first post-operative day physiotherapy course is commenced with aim to restore full range of joint movements. Regenerative therapies such as bone marrow derived mesenchymal stem cells or platelet rich plasma may be beneficial in these cases.2325 Recheck ultrasound and lameness examinations should be performed periodically. Comparison to the contralateral limb is recommended. Horses typically present following a history of direct trauma or acute, severe lameness. The prognosis for return to use in partial collateral ligament injury is good; however, horses with secondary osteoarthritis or those that have subluxation of the elbow joint may have persistent osteoarthritis and thus have a more guarded prognosis. The resultant lameness after this acute phase is dependent upon the degree of injury to the region if the elbow is destabilized.3, Horses will typically have a severe lameness and may have soft tissue swelling over the corresponding trauma. These horses may display swelling around or near the point of the elbow and may be sensitive to palpation in this area depending upon the degree and configuration of the fracture.3 Contrary to other horses with a dropped elbow appearance, such as those with complete humeral fractures or radial neuropathy, these horses may be able to bear weight on the limb (minimally displaced fractures). Shoulder bursae are inflammation that is caused in small fluid-filled sack. Patients develop limited movements in one or several directions (inability to straighten or bend the elbow) or in both directions (inability to achieve full movement amplitude). Most horses will have significant swelling over the site of fracture. Horses with elbow arthritis have variable grades of forelimb lameness. There are reported cases of radial stress fractures albeit rare. 18.1). They require separate treatment. The limb may be warm to the touch and attempts at flexing or extending the elbow joint will typically result in pain. First aid therapy in displaced open fractures is to clip the open wound and thoroughly clean the area with dilute saline solution. There is so much range of movement that it is surprising more shoulder injuries don't occur. If the skin is irritated, an open wound may communicate with the bursa.21. The leg should be bandaged and a full limb caudal splint from elbow to fetlock should be applied to lock the carpus in extension. The non-septic swelling typically contains fluid, fibrous tissue or both.21 If the skin is damaged it is possible that there may be a wound and associated local infection. The non-septic swelling typically contains fluid, fibrous tissue or both.21 If the skin is damaged it is possible that there may be a wound and associated local infection. As previously mentioned, these fractures usually result from direct trauma and most are comminuted.17 Potentially, radial stress fractures may propagate into complete, displaced fractures if not treated appropriately. Ultrasound is the diagnostic method of choice for collateral ligament injuries. Ultrasound can also be very useful to evaluate the ligament. Frozen shoulder cause formation of scar tissues in the capsule of shoulder joint. Also of note are the osseous fragments on the medial aspect of the limb. Radiography is the most common way to confirm the diagnosis (Fig. Olecranon bursitis Collateral ligament injury/luxation Horses will typically have a severe lameness and may have soft tissue swelling over the corresponding trauma. Although there have been successful attempts at internal fixation, oftentimes the internal fixation cannot withstand the forces applied to the radius. Radiography with stressed views can help determine joint stability or confirm complete ligament rupture as well as evaluate for avulsion fragments or osteoarthritis. Lateral collateral ligament rupture. Also of note are the osseous fragments on the medial aspect of the limb. Horses that have had a recent injection into the elbow that become acutely lame should be considered septic until proven otherwise. The ball, or head, of the upper arm bone fits into a rounded socket (glenoid) in the shoulder blade. Osteoarthritis is typically secondary to degenerative or traumatic causes. In addition, the Internet (Google) and Medline (PubMed) were used to search for publications related to a national shoulder or elbow joint replacement registry. Affected horses may also have a visible deviation in the limb or palpable crepitance. Therapeutic aims Local wounds in open fractures should be clipped of hair and cleaned. As the edema subsides, a fluid pocket remains. repaired with internal fixation. Epidemiology The prognosis for return to use in partial collateral ligament injury is good; however, horses with secondary osteoarthritis or those that have subluxation of the elbow joint may have persistent osteoarthritis and thus have a more guarded prognosis. Horses present with a variable degree of lameness, but it is typically severe in the acute stages. The attachment of the triceps muscle group to the olecranon is the main source for extension of the elbow joint.1, Diagnosis of elbow disease is uncommon in the equine athlete, but can be due to developmental, traumatic, infectious, or non-septic inflammatory causes. Latero-medial and cranio-caudal radiographic projections are recommended to assess the fracture configuration and to determine if there is an articular component. The prognosis of adult horses with complete radial fractures is poor. Many of these horses become more comfortable with the splint applied. Collateral ligament injury typically occurs from trauma or a fall. The joint undergoes a large range of motion; however, due to the soft tissue attachments and bone articulation, joint movement is restricted to the sagittal plane. Many different fracture configurations are possible and most are amenable to repair or successful conservative therapy. Left image: From Baxter, G.M., 2002, Management of Bursitis, in Equine Surgery, 4th edn, Auer, J.A., and Stick, J.A., eds, with permission from Elsevier. Anatomy Etiology and pathophysiology Joint excursions at the shoulder, elbow, and wrist were all on average 20 during touchscreen interaction. A favorable prognosis can be achieved with most olecranon fractures. Stress fractures may be visible radiographically, but may require nuclear scintigraphy in certain cases. Collateral ligament injury is rare as well as subluxations of the elbow joint. Horses with advanced sepsis in the elbow joint have a severe (grade 4 or 5) lameness, which is due to joint distention secondary to the inflammation. Horses with septic arthritis will have a severe lameness that may be variable depending upon the degree of infection. Many different fracture configurations are possible and most are amenable to repair or successful conservative therapy. The best way to confirm the diagnosis is with radiography (Fig. The radial nerve innervates the flexor muscles of the shoulder joint and extensors of the elbow, carpus, fetlock and interphalangeal joints. Prognosis This stall confinement is recommended for 34 months prior to attempting short handwalks with periodic radiographic assessment of fracture healing. Notice the irregularity of the proximal radial physis. In contrast, when the elbow was flexed at 90, the anterior deltoid and subscapularis were the greatest contributors to joint angular acceleration in abduction. The cause of these collateral ligament tears is due to trauma either from a direct kick or the horse getting the limb lodged in a fence. Golfers elbow occur due to the repeated bending movements of the palm, as a result muscles of the palm and fingers are overloaded, as well as attachment places of tendons, causing inflammation, swelling and pain in elbow joint. There is typically no lameness. Cytological differential cell counts will have a predominantly (>90%) mononuclear cell population. Biceps brachii tendonitis Physical examination Septic elbow arthritis The medial collateral ligament is also covered by the transverse pectoral muscle making palpation of this ligament more difficult than the lateral collateral ligament.1 The muscles that aid in flexion of the joint consist of the biceps brachii and brachialis. Many of these horses become more comfortable with the splint applied. How can I have tennis elbow pain? Once diagnosed, lifetime treatment is typically required. A wound over the radius may be present and is commonly on the medial aspect of the limb due to decreased soft tissue coverage in this area. This ulnar fracture was diagnosed with radiography and not suspected to be articular nor disrupt the triceps apparatus. Ultrasound is the diagnostic method of choice for collateral ligament injuries. Olecranon bursitis Numerous oral supplements are available to reduce inflammation, but the authors typically only recommend those that have undergone testing such as glucosamine and chondroitin sulfate, specifically brands such as Cosequin ASU (Nutramax Laboratories, Inc Edgewood, MD, USA) as they have been tested for their contents and studied in clinical trials. Still the reason of illness has not been discovered globally but its course can be observed. High-resolution ultrasound may be beneficial in locating breaks within the periosteum; however, the methods mentioned above are preferred. History and presenting complaint Radiographs are useful in ruling out concurrent osseous damage. Acute injuries or those with open wounds into the joint will typically have a less severe lameness until the joint distention occurs.
