65
Management of metacarpal base + shaft #
Splinting
Reduction (for transverse fractures, isolated spiral/oblique fractures with <3 mm of shortening, and extra-articular fractures of the thumb)
Closed reduction of metacarpal shaft fractures is performed with longitudinal traction, dorsal pressure at the fracture site, and rotation as needed.
Closed reduction of extra-articular base fractures typically requires only longitudinal traction.
Post reduction XRs + XRs 1 wk after
Ulnar gutter splint for 3 to 4 wk for extra-articular metacarpal base fractures if ring and/or little finger(s) are involved
Volar or radial gutter for 3 to 4 wk for extra-articular metacarpal base fractures of index and long finger
Functional brace (Galveston) if fracture requires significant reduction
Thumb spica cast for extra-articular fractures of the thumb for 4 to 6 wk
Referrals
Referral is needed for unstable or unsatisfactory reductions in children.
Long oblique and spiral fractures typically require closed reduction and percutaneous pinning in children
Metacarpal fractures that are more distal and ulnar are better tolerated and are more amendable to nonoperative treatment
66
What is a Stener lesion?
An injury that occurs in the thumb, specifically involving the ulnar collateral ligament (UCL) of the metacarpophalangeal (MCP) joint. It is a complication of a complete rupture of the UCL, commonly caused by trauma such as a fall on an outstretched thumb or forced thumb abduction.
In a Stener lesion, the torn UCL becomes displaced proximally and gets caught above the adductor aponeurosis.
This effectively prevents healing without surgical intervention
Common w/ complete tear

UCL Injury +/- avulsion #
68

Dorsal laceration: extensors and retinaculum
77

X-rays may be normal initially, therefore immobilization in thumb spica and repeat x-rays are recommended in 2 weeks if there is clinical suspicion.
If suspicion is still high, can do MRI for radiologically occult fractures.
81
Management of acute scaphoid #
Stable, non-displaced, waist or distal pole fractures: Immobilization in thumb spica splint or cast. The immobilization time is longer than for other upper extremity fractures. Need to regularly follow and document radiologic healing.
Distal third fractures: 4-6 weeks.
Waist fractures: 6-12 weeks.
Proximal third fractures: Up to 12-16 weeks due to slower healing and higher risk of avascular necrosis (AVN).
Unstable, displaced > 1mm, vertical or oblique, proximal pole fractures, or any concerning features: Immobilization in thumb spica splint or cast and refer to orthopedics for surgery, semi-urgent.

What is a Mallet finger?
Mallet finger is defined as a stretching or tearing of the extensor tendon or a complete avulsion of the tendon insertion from the dorsal base of the distal phalanx with or without bony avulsion
A mallet finger occurs when the extensor tendon at the distal interphalangeal (DIP) joint is injured, preventing active extension of the fingertip.
Typically caused by a direct blow to the fingertip (e.g., a ball striking the finger), forcing it into sudden flexion while the extensor tendon is under tension.
85
MOI Mallet finger
Sudden forced flexion of the fingertip while the DIP joint is actively extended (struck on tip of finger by ball)
Less commonly, it can occur when the DIP joint is forcefully hyperextended with a resulting fracture at the dorsal base of the distal phalanx

6-8 wks
Monitor compliance at 2 wk intervals
At the end of continuous immobilization, if a mallet deformity of >20 degrees recurs, continue splinting for an additional 1 to 2 mo.
Consider extension splinting during athletic activities for an additional 2 mo after continuous splinting has been completed.
After splinting, ROM exercises
89

Swan neck deformity if untreated or poor compliance
90
What is a Jersey finger?

91
MOI Jersey finger
In classic cases this injury happens when a player goes to grab a jersey of an opponent. The DIP is in flexion, holding onto the jersey, and then is suddenly pulled into extension as the opponent pulls away. This causes avulsion of the FDP tendon off the distal phalanx

Physical for athletic pubalgia
Resisted sit up = painful
Single or bilateral resisted leg adduction = painful
Diagnosis of sports hernia may be made if at least three of the following five signs exist:
Pinpoint tenderness to the pubic tubercle at conjoint tendon insertion
Tenderness over deep inguinal ring
Pain and/or dilation of the external ring with no palpable hernia
Pain at origin of adductor longus tendon
Dull diffuse groin pain often radiating to perineum and inner thigh or across the midline
Complete exam for other causes of groin pain should be performed:
Hip adductor origin tenderness AND pain with resisted adduction suggest adductor-related groin pain.
Tenderness at pubic symphysis suggests pubic-related groin pain.
Pain with resisted hip flexion AND/OR stretching of hip flexors suggests iliopsoas-related groin pain.
Hip joint–related groin pain may elicit pain with passive range of motion (ROM); flexion, adduction, and internal rotation (FADIR); and flexion, abduction, external rotation (FABER) tests.

Phase 3 (3 to 5 wk): Maintain full extension and increase flexion up to full ROM; stair climbers and stationary cycle may be used.
Phase 4 (6 wk to 9 mo): Increase strength and agility; progressive return to sports
181

In the acute setting, start isometric quadriceps exercises and straight-leg lifts.
Electrical stimulation/biofeedback to vastus medialis oblique (VMO) quads
Gentle hamstring and calf strengthening in protective ROM
ROM exercises with progression to full ROM over 4 to 8 wk to allow ligament to heal without too much stress
Stair stepper or similar for cardiovascular (CV) conditioning can be added, limiting knee flexion to 45 to 60 degrees when tolerated.
Stationary bike later in rehabilitation when able to flex knee to 115 degrees without pain or residual swelling afterwards
When gait is normal, begin jogging and enhanced resistance exercises.
Progress to half sprints, full sprints, and cutting maneuvers once ligament fully healed
