A 45-year-old construction worker sustains a fall and presents with an isolated injury to his upper extremity. Radiographs of the affected wrist are shown in Figure A. After soft tissue swelling subsides, open reduction and internal fixation of the distal radius is performed. Following fixation, a "shuck" test is performed and shows persistent instability of the distal radioulnar joint. Incompetence of which of the following anatomic structures is the most likely etiology of this finding?
Radioulnar ligaments of the TFCC
Ulnar collateral ligament
Ulnolunate ligament of the TFCC
Ulnotriquetral ligament of the TFCC

A 68-year-old male falls onto his outstretched hand and suffers the injury shown in Figures A and B. He undergoes operative treatment of his fracture, and immediate post-op radiographs are shown in Figure C. Two weeks later he presents with significantly increased pain and deformity. He denies any new trauma, and has followed all post-operative activity restrictions. Current radiographs are shown in Figure D and a clinical photograph of the affected wrist is shown in Figure E. Which of the following is the most likely cause for failure of fixation in this patient?
Failure to support the lunate facet with fragment specific fixation
Use of a non-locking plate
Lack of volar tilt restoration
Lack of radial styloid column plating
Use of only three bicortical screws in the intact radial shaft proximally
A 17-year-old male falls from a retaining wall onto his left arm. He sustains the injury shown in Figure A. The patient undergoes open reduction and internal fixation of the fracture. Upon discharge from the hospital the medication reconciliation includes an order for daily Vitamin C 500mg supplementation. This medication is given in an effort to decrease the incidence of which of the following?
Upper extremity deep vein thrombosis (DVT)
Acute carpal tunnel syndrome (ACTS)
Complex regional pain syndrome (CRPS)
Lower extremity deep vein thrombosis (DVT)
Surgical site infection (SSI)
A 65-year-old female sustains a fall onto her outstretched right hand. The injury is closed and she is neurovascularly intact. There is no median nerve paresthesias. Radiographs are shown in Figures A and B. What is the next best step in management of this patient?
Admit for acute carpal tunnel syndrome monitoring
Admit for acute open reduction/internal fixation
Place into removable soft splint and follow-up in clinic
Place into rigid splint and follow-up in clinic
Place into rigid splint and schedule for outpatient open reduction/internal fixation
A 63-year-old female sustained a distal radius and associated ulnar styloid fracture 3 months ago after being involved in a motor vehicle collision. Radiographs obtained at the time of injury are shown in Figure A. She underwent open reduction and fixation of the distal radius fracture, and current radiographs are shown in Figure B. At the time of the index operation, there was no distal radioulnar joint instability after plating of the radius. Which of the following is true post-operatively regarding this patient's ulnar styloid fracture?
Worse outcomes on the Mayo wrist score are expected without fixation
Chronic distal radioulnar joint instability can be expected to occur without fixation
Wrist function depends on the level of ulnar styloid fracture and initial displacement
Grip strength and wrist range of motion are improved with fixation
There is no adverse effect on wrist function or stability without fixation
A 67-year-old woman slips on the ice while retrieving her mail and lands on her outstretched left hand. She complains of wrist pain and deformity. On physical exam she has no sensation of the volar thumb, index, and middle fingers. Radiographs are provided in Figure A. Two hours following closed reduction, the deformity is corrected, but the numbness and wrist pain is worsening. Which of the following interventions should be taken?
Evaluation of volar compartment pressures with a needle monitor
Icing and elevation of the arm with follow-up evaluation in 8 hours
Immediate EMG evaluation of the left upper extremity
Closed reduction, carpal tunnel release, and sugar tong splinting
Emergent open reduction internal fixation with carpal tunnel release
A 64-year-old female sustains a nondisplaced distal radius fracture and undergoes closed treatment using a cast. Three months after the fracture she reports an acute loss of her ability to extend her thumb. What is the most likely etiology of her new loss of function?
Posterior interosseous nerve entrapment
Extensor pollicis longus rupture
Extensor pollicis longus entrapment
Distal radius malunion
A 51-year-old female presents with an acute inability to extend her thumb, four months after she was treated with cast immobilization for a minimally-displaced distal radius fracture. What is the most appropriate treatment at this time?
Occupational therapy for strengthening
Extensor carpi radialis longus transfer to extensor pollicus longus
Extensor pollicis brevis transfer to extensor pollicus longus
Extensor indicis proprius transfer to extensor pollicus longus
Primary repair of extensor pollicus longus
Twelve months after open reduction and internal fixation of a comminuted distal radius fracture as seen in Figure A and B, which of the following tendons is at greatest risk of rupture?
Abductor Pollicis Longus
Extensor Pollicis Brevis
Extensor Indicis Proprius
Flexor Pollicis Brevis
Flexor Pollicis Longus
A 54-year-old male falls from a ladder and sustains the fracture shown in Figure A. Which of the following factors has been associated with redisplacement of the fracture after closed manipulation?
Triangular fibrocartilage complex tear
Ipsilateral radial head fracture
Time to reduction
Severity of initial displacement
A 46-year-old woman sustains an extra-articular fracture of the distal radius and undergoes open reduction and internal fixation with a volar plate and screw construct. During postoperative recovery from this injury, what benefit does formal physical therapy have as compared to a patient-guided home exercise program?
Greater grip strength at 6 months
Less wrist pain at 1 year
Better hand dexterity at 1 year
No difference in functional outcomes
Quicker return to work
Spontaneous rupture of the extensor pollicis longus tendon is most frequently associated with which of the following scenarios?
Non-displaced distal radius fracture
Non-displaced Rolando fracture
Second metacarpal base fracture
Non-displaced radial styloid fracture
A 25-year-old female falls from her horse and injures her left wrist. There are no open wounds and the hand is neurovascularly intact. Radiographs are provided in Figures A-C. Which of the following will best achieve anatomic reduction, restore function, and prevent future degenerative changes of the wrist?
Long arm cast above the elbow for 6 weeks
Long arm cast for 3 weeks followed by a short arm cast for 3 additional weeks
Closed reduction and external fixation
Closed reduction and percutaneous pinning
Open reduction and internal fixation
A 70-year-old woman with known osteoporosis sustains a distal radius fracture of her dominant arm with some metaphyseal comminution. Adequate maintenance of reduction by non-operative treatment is unsuccesful. Which plating option provides the most appropriate treatment of this fracture?
limited-contact dynamic compression
A 58-year-old man underwent distal radius ORIF with a volar locking plate yesterday. Preoperatively, he reported some mild sensory disturbances in the volar thumb and index finger, but had 2-point discrimination of 6mm in each finger. Now, he complains of worsening hand pain and sensory disturbances in his volar thumb and index finger. Two-point discrimination is now >10mm in these fingers. Radiographs show a well-fixed fracture in good alignment. What is the most appropriate treatment at this time?
Removal of hardware
Immediate carpal tunnel release
Carpal tunnel release if no resolution at 6-12 weeks
Trial of night splinting
A 32-year-old ballet dancer sustains a distal radius fracture, and is subsequently closed reduced and casted. She presents 11 months later with the radiograph seen in Figure A, complaining of significant wrist pain. What is the appropriate surgical treatment at this time?

Total wrist arthrodesis
Proximal row carpectomy
