Finger Common Fractures MALLET FINGER( Baseball Finger) Diane L. Gorgas, MD Associate Professor & Residency Director Department of Emergency Medicine • Avulsion of Extensor Digitorum Communis (EDC) Tendon from DIP joint The Ohio State University PITFALL – get the films • Can be associated with Avulsion Fracture Common Fractures Finger Distal Upper Extremity MALLET FINGER – Fingers, Hand, Wrist • Mechanism of Injury: • Direct jam Proximal Upper Extremity • Forced flexion – Humerus, Shoulder, Clavicle • Dorsal dislocation of PIP Proximal Lower Extremity • Laceration – Hip, Femur • Splint Distal Lower extremity • Slight hyperextension for 6 weeks – Knees, Ankle, Feet • Night splint for additional 6 weeks • Best results if treated early 1 Jersey Finger Finger JERSEY FINGER • Avulsion injury of Flexor Digitorum Profundus (FDP) from volar base of distal phalanx • Examination: •FDP test - blocked flexion of DIP • Treatment - early surgical repair • Permanent disability if missed Jersey Finger Neuro Hand Sensation • A pop or rip felt in the finger at the time of the injury ulnar • -Painwhen moving the injured finger and the inability to bend the las tjitt joint radial • - Tenderness, swelling and warmth of the injured finger median • - Bruising after 48 hours • - Occasionally a lump felt in the palm of the finger 2 Neuro Hand Strength Boxer’s Fracture DEFINITION ulnar • Distal neck fx of 5th metacarpal • Volar displacement acceptable to 45 degrees for office casting +/- closed reduction • Rotation deformity radial • Referral median • More than minimal valgus or varus displacement • Referral • PITFALLS – missing a fight bite Boxer’s Fracture Boxer’s Fracture 3 Metacarpal Bones Thumb Immobilization BENNETT’S FRACTURE • Thumb Spica Splinting • Intra-articular fx at base of 1st metacarpal • Wide displacement due to pull of FPL • Fragment held in place by strong ligament Wrist & Hand Injuries • Scapholunate Ligament Injury – Most common and most crucial ligament injury of wrist. – Often leads to chronic pain and/or functional instability. PITFALL – Only looking for fractures 4 Scapholunate Ligament Injury Wrist Injuries • Scaphoid fractures – Most common carpal bone injury of wrist. – Can be radiographically occult – PITFALL - splint – Can lead to avascular necrosis of scaphoid if unrecognized. Terry Thomas/David Wrist Injuries Letterman • Triquetral Fractures – Second most common fracture – PITFALL – not looking at Lateral film 5 “Wrist” Injuries Supracondylar Fracture • Distal radius/ulna • Mechanism: fall injury patterns on flexed elbow Colle’sfractures s fractures • PITFALL; Smith’s fractures – median nerve (reverse Colle’s) injury PITFALL- R,M,U – Brachial disruption 8% artery injury Elbow Fractures Humerus Fractures • Radial Head Fracture – Sail Sign – PITFALL- – No boney abnormality, no fracture 6 Humerus Fractures Clavicle Fracture • PITFALL - Radial Nerve • PITFALLS • Transection CHECKING FOR VASCULAR • Neuropraxia INTEGRITY ASSOCIATED INJURIES SKIN TENTING Clavicle Fracture Shoulder Dislocations 7 Shoulder Dislocations Knee Injuries • Anterior Most common •Scaphoid deformity •Flexed and adducted • Posterior Seizures PITFALL – not controlling seizures • Inferior/Thoracic Hip Fractures Knee Injuries • PITFALLS Recognizing • Patella Alta - PITFALL Occult • Patellar fractures – fractures PITFALL – check Addressing extensor mechanism high morbidity 8 Common Knee Fractures Ankle Fractures • Bi and Tri malleolar fractures • Mortis disruption • Misnomer Mechanism of Ankle Ankle Fractures Injuury • PITFALL • Inversion + Plantarflexion= 80% sprains – Examining the joint above and – Most commonly involve the Anterior below Talofibular Ligament. • Inversion or Eversion alone • Landing on unsteady object • Change of Direction – Deceleration associated • Manual Twisting – Wrestling injury 9 Proximal 5th Metatarsal Palpation Common Fractures in • Test of 5th Metatarsal Avulsion Orthopedics – Occurs most commonly with inversion – Peroneus Brevis pulls styloid off of Michael Quackenbush, DO 5th Metatarsal Assistant Professor Orthopaedic Trauma – PITFALL - Palpate at styloid for pain. Ohio State University Medical Center • If positive for pain should X-ray. 5th Metatarsal Fractures Adult Common Fractures Objectives 1. Recommend an approach to the • Jones versus evaluation of patients who present with pseudo Jones a fracture 2. Identify operative and non-operative PITFALL – injuries commonly seen in orthopedics nonreferal of 3. Describe basic surgical treatment options for fractures Jones 4. Understand goals of surgery and what your patients can expect during post operative period 10 Evaluation Clinical Evaluation • Patients age • Need to closely exam the • History soft tissues around the – Time of injury fracture – Mechanism of injury • Look for openings in the – “What hurts hurts” skin – which may • Medical History indicate an “open” • Surgical History fracture • Social Hx (occupation) • Medications • Abrasions? Amount of (anticoagulation) swelling? Presence of • Smoking/Alcohol history fracture blisters? Physical Examination Clinical Evaluation • Soft tissue care • Look for deformity – Primary goal is to halt • Palpate areas of continuing trauma to the tenderness tissues • Examine the joint – Treatment of fractures first above and below begins with “reducing” the • Detailed neurologic fracture or dislocation and vascular – Immobilizing the fracture examination with a splint or external fixation 11 Clinical Evaluation Imaging Studies • Soft tissue care • Some instances plain x-rays do not define the fracture well – Primary goal is to halt – Joint injuries with multiple fragment continuing trauma to the => CT scan tissues – OltftOccult fractures – Treatment of fractures first begins with “reducing” the fracture or dislocation – Immobilizing the fracture with a splint or external fixation Imaging studies Special Studies • Elderly patients with hip pain => MRI can • Radiographic assessment of fractures diagnose an occult hip • Begins with plain x-rays fracture – 2 views at l east • Occult Fractures – AP (anteroposterior) and lateral – Bone Scan views • Sensitivity 100% – Joints above and below as some of @ 72hrs the energy can be absorbed at a site – MRI away from the injury • Sensitive in first 24 hrs 12 Now that we have a diagnosis, Treatment where do we go from here?
