Injury Evaluation History Ask questions: How, where, when, who Observation What do you see? Swelling, bruising, deformity Palpation What do you feel? Instability, deformity, defects Special Tests What structures are damaged? How stable is the joint? Are they point tender?
Slide 9-

Injury Prevention Acute injuries usually occur from trauma or falling Wear protective padding to reduce the force of a blow Learning how to fall correctly Chronic injuries are very common in the elbow, forearm and wrist Limit # of repetitions throwing or hitting a tennis ball Make sure of proper mechanics Maintain appropriate strength and endurance levels Stretch to warm up & stretch to cool down Don’t overlook chronic injuries. REST if needed!
Slide 10-

Cause: Can be caused by a direct blow, falling on the tip of the elbow or excessive flexion/extension. This injury can be acute or chronic Signs & Symptoms: Excessive swelling that appears to be superficial, redness, warmth Care: Ice, rest, compression sleeve. On rare occasions, the elbow is drained. Pad when return to play. Athlete may take NSAIDs to reduce swelling. Ultrasound may be used if this is a chronic condition Olecranon Bursitis
Slide 11-

Olecranon Bursitis
Slide 12-

Cause: Hyperextension or excessive Valgus Force. This injury usually occurs during the cocking phase of the throwing motion Signs & Symptoms: Pain, Instability, numbness & tingling, Point tenderness over the UCL Care: Ice, compression sleeve, sling, rest. Follow up with a physician for evaluation, x-ray & MRI if necessary. Surgery is required to repair the injury. Recovery after surgery is approximately 9 months During rehabilitation throwing is restricted for the first 12 weeks. After 12 weeks, throwing is controlled by limiting & gradually progressing the number of throws per day Ulnar Collateral Ligament Sprain

Cause: Typically happens as a result of a weak or torn UCL. It can become strained, chronically dislocated, or impinged Signs & Symptoms: Paresthesia or burning in fourth & fifth fingers, weakness in forearm Care: treat conservatively by rest & restricting aggravation motions. Surgery may be required. Do not compress the nerve with outside pressure Ulnar Nerve Injury

Slide 27-

Cause: Fall on outstretched hand, fall on flexed elbow, direct blow or trauma to elbow Signs & Symptoms: May not see a visible deformity. Hemorrhage, swelling, muscle spasms Care: Ice, sling or splint, immediate referral to ER for x-ray & cast. Casting (immobilization) is typically limited to 3 weeks. After 3 wks., patient is moved to splint/brace that stabilizes but allows motion Elbow Fracture

Elbow Fracture
Slide 29-

Elbow Fracture
Slide 30-

A fractured elbow is associated with rapid swelling that may cause a Volkmann’s contracture. Volkmann's contracture results from acute ischemia/necrosis of the muscle fibers of the flexor muscles in the forearm caused by obstruction of the brachial artery near the elbow. The obstruction may be caused by improper tourniquet use, improper casting, compartment syndrome, or profuse bleeding of fractured bones. The two most affected muscles are the flexor digitorum profundus & flexor pollicis longus. Volkmann’s Contracture

Forearm Injury Evaluation History: how did it happen, where does it hurt, prior injury, loss of function, symptoms Observation: swelling, deformity, discoloration, skin defects, motion Palpation: tenderness, edema, deformity, skin temperature, bone fragments, continuity of bone
Slide 36-

Cause: repeated blows to the forearm or a blow with significant force. Typically occur on the ulnar side Signs & Symptoms: bruising, pain, swelling, hematoma, myositis ossificans may develop if the injury is severe Care: P.R.I.C.E., stretching, Range of motion exercises, Pad/Protect to return to play Contusion
Slide 37-

Cause: typically caused by a blow or falling on an outstretched hand Signs & Symptoms: Pain, swelling, deformity, ‘false joint’. There is a danger of soft tissue damage if the fractured bones move significantly Care: Splint & immediately refer for x-ray & physician consult. Ice. Typically casted for 6-8 weeks, surgery may be required if the deformity is significant. Take Tylenol for pain, NOT Ibuprofen. Ibuprofen can delay fracture healing by hindering the inflammatory response phase Forearm Fracture

Slide 41-

Cause: fall on outstretched hand forces the wrist into hyperextension. The most common forearm fracture. Distal Radius Fracture. Signs & Symptoms: visible deformity, pain, swelling, quick accumulation of blood. Median nerve damage is possible if the radius shifts forward enough Care: Splint & immediately refer for x-ray & physician consult. Ice. Typically casted for 4-8 weeks. Fracture deformity is usually reduced under anesthesia. Colles’ Fracture

Slide 60-

Phalanx Fracture
Slide 61-

Cause: Contusion or crushing injury to the first phalanx that causes blood to accumulate under the nail Signs & Symptoms: Extreme pain, blood under nail, more than 25% fracture needs to be ruled out Care: Drain within 12 to 24 hours, ice, elevate, clean once drilled, may have to be drilled twice, keep clean & covered. DO NOT DRILL THE NAIL IF A FRACTURE IS SUSPECTED!!! Subungual Hematoma
Slide 62-

Cause: a wrist sprain is caused by Hyperextension most often, but it can be caused by violent flexion or torsion Make sure the athlete gets an x-ray to rule out a fracture. Care: ice, splinting & analgesics, strengthening exercises, & taping to return to play Wrist Sprain
Slide 63-

Cause: repetitive wrist acceleration & deceleration Signs & Symptoms: Pain with use or pain with passive stretching. Point tender with swelling over the tendon Care: Ice massage, NSAIDs, rest, & splint injured tendon Wrist Tenosynovitis (Tendinitis)
Slide 64-

Cause: Carpal Tunnel is caused by inflammation of the flexor tendons that compress the median nerve Signs & Symptoms: Sensory & motor deficits Tingling & numbness Paresthesia of thumb, index & middle fingers. Weakness in thumb, index & middle fingers Aching in hand Care: Rest Wrist splint NSAIDS Injection of corticosteroid Surgery Carpal Tunnel Syndrome
Slide 65-

Carpal Tunnel Syndrome
Slide 66-

Caused by forceful hyperextension Not very common in sports Pain, swelling, deformity, difficulty with flexion May have numbness or paralysis due to pressure on the median nerve See physician immediately for x-ray and reduction. Cast for 4-8 weeks Dislocated Lunate
Slide 67-

Dislocated Lunate
Slide 68-

Scaphoid Fracture Scaphoid is found in the anatomical snuff box Typically caused by falling on outstretched hand Signs & symptoms include swelling & severe point tenderness, loss of grip strength, weakness with thumb movement Athlete should be x-rayed immediately, immobilized in a cast Rexray athlete every 2 weeks, & remain in splint if fx. Shows up. If a fracture is present, immobilization period is typically around 6 weeks The scaphoid doesn’t have good blood supply, which can result in a non-union Non-union fracture healing must be repaired with surgery When athlete returns to play once out of cast, they must be taped for 8-12 weeks
Slide 69-
