pain-free AROM of shoulder, wrist (flex only), and fingers. AAROM into wrist ext with elbow flexed to 90, PROM into elbow flex/ext and pro/sup
33
Lateral epicondylar release protocol 2 weeks on

- a skin dimple can be seen proximal to radial head
- with increased flexion the dimple disappears as the radial head reduces
con- may have apprehension
in anesthetized patient, 100% SN
97
chronic cases of PLRI

- return to sport when strength is 85%-90% equal
99
posterior elbow impingement
common injury in throwers due to high amount of valgus torque and rapid extension occurs during pitching
can lead to compromise of integrity of UCL, producing a radiocapitellar overload syndrome and valgus extension overload
100
6 phases of throwing
wind up
early cocking
late cocking
acceleration
deceleration
follow through
101
acceleration phase of throwing
generates the most valgus force at the elbow
102
deceleration phase of throwing
the dissipation of the forces creates pathological forces in the posterior elbow , generating a reactive bone formation on the olecranon's posteromedial tip.
- can lead to osteophyte development or the occurrence of loose bodies that may result in impingement.
103
most SN test for posterior impingement
moving valgus stress test

110
Osteochondritis dissecans of the capitulum

MRI or CT often needed
115
OCD treatment

- unstable lesions require osteochondral autologous transplantation surgery
- nonop approach lasts between 3-4 months and focuses on pain control, non abusive activity with biceps/triceps
116
Heterotropic ossification
- ectopic ossification of myositis ossificans
- bone formation at an atypical site
