1 Care and Prevention of athletic injuries Chapter 12 Ms. K Hand &WristCare and Prevention of athletic injuriesChapter 12Ms. K
2 WRIST & 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
3 WRIST & HAND ANATOMY Ligaments: Triangular fibrocartilage complex Every finger has 2 collateral ligamentsRadial/lateral collateral ligamentUlnar/Medial collateral ligamentTriangular fibrocartilage complex
4 Anatomical 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.
5 TFCC The Triangular fibrocartilage complex (TFCC) is formed by: Triangular fibrocartilage discus (TFC)Radioulnar ligaments (RUL’s)Ulnocarpal ligaments (UCL’s).
6 DeQuervain’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
7 Mallet 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
8 Jersey 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
9 Wrist Sprain Management: MOI: FOOSH Excessive radial/ulnar deviation Signs/SymptomsPainDecreased ROMDecreased grip strengthSwellingLaxityManagement:RICESplintRehab to strengthen hand muscles
10 Ganglion 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
11 Gamekeeper’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
12 Interphalangeal 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
13 Dislocation 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
