1Care and Prevention of athletic injuries Chapter 12 Ms. K Hand &WristCare and Prevention of athletic injuriesChapter 12Ms. K
2WRIST & HAND ANATOMY Fingers named by #1-5 starting at the thumb Joints named after the bones that come togetherMuscles:Wrist extensors are posterior on the forearmWrist flexors are anterior on the forearm
3WRIST & HAND ANATOMY Ligaments: Triangular fibrocartilage complex Every finger has 2 collateral ligamentsRadial/lateral collateral ligamentUlnar/Medial collateral ligamentTriangular fibrocartilage complex
4Anatomical Snuff Box The boundaries The posterior border of the snuffbox is the tendon of the extensor pollicis longus.The anterior border are the extensor pollicis brevis and the abductor pollicis longus.The proximal border is formed by the styloid process of the radiusThe floor of the snuffbox varies depending on the position of the wrist, but both the trapezium and primarily the scaphoid can be palpated.
5TFCC The Triangular fibrocartilage complex (TFCC) is formed by: Triangular fibrocartilage discus (TFC)Radioulnar ligaments (RUL’s)Ulnocarpal ligaments (UCL’s).
6DeQuervain’s Tendonitis Tendonitis of the abductor pollicus longus and extensor pollicus brevis (muscles that move that thumb)AKA as “Trigger Finger”MOI: Repetitive motion (radial deviation) of the wristSigns/Symptoms:Pn with abductionSwellingCrepitusTreatment:RICENSAIDSStrengthening of hand muscles
7Mallet Finger MOI: Hit at the tip of the finger Extensor tendon tears from boneSigns/Symptoms:Finger is in flexionCannot straighten finger because tendon is unattachedManagement:PainSwellingSplint in extensionSurgery to reattach
8Jersey Finger Flexor tendon tears away from fingertip MOI: DIP jt is in flexion and is suddenly forced to extend (i.e. grabbing a jersey)Signs/Symptoms:PainSwellingDIP jt is unable to flexManagement:SplintIceSurgery
9Wrist Sprain Management: MOI: FOOSH Excessive radial/ulnar deviation Signs/SymptomsPainDecreased ROMDecreased grip strengthSwellingLaxityManagement:RICESplintRehab to strengthen hand muscles
10Ganglion CystOccurs when the sheath covering the muscles becomes filled with fluidA.K.A. “Bible’s cyst”Signs/Symptoms:Bubble develops on wristPainful at timesManagement:Ice with compressionIf persistent, needs to be drained by physician
11Gamekeeper’s ThumbMOI: Injury to medial collateral ligament of thumb due to forced abduction(i.e. catching a basketball)Signs/Symptoms:PainSwellingLoss of ROMManagement:IceSplintXray to r/o fx
12Interphalangeal Collateral Ligament Sprain MOI: Joint is stressed beyond normal limitsI.e. finger hits a ball, land with fingers extended or curledSigns/Symptoms:PainSwollenEcchymosisLoss of ROMManagement:XRAY to r/o fxIce in ice cupSplint
13Dislocation of Interphalangeal or Metacarpophalangeal Joints MOI: Bones of joint are forced in opposite directionsSigns/Symptoms:Obvious deformityPain, SwellingEcchymosisLoss of ROMManagement:Refer to physician for reduction
