transverse rotation was greater in players with pain (109 degrees
versus 87 degrees; p
<
.05), and Upper torso shoulder angular velocity
were significantly higher in participants with pain compared to those
without by 22% 19%, respectively (both p
<
.05). Shoulder muscle
strength was not different between groups.
Conclusions:
The presence of shoulder pain was related to male sex,
offensive positions and fast rotational motion. These findings may help
physiatrists 1) preemptively pre-habilitate lacrosse athletes at higher
likelihood of developing chronic shoulder pain and 2) prevent sec-
ondary injuries through movement and hand positioning.

Objective:
The aim of the present study was to verify the modified
thread carpal tunnel release procedure clinically.
Design:
Retrospective study.
Setting:
Clinical procedure room.
Participants:
To date, a total 159 TCTR procedures have been per-
formed on 116 patients. The average age of patients was 54.83 with an
age range of 26 to 84 years. There were 39 males and 77 females. Of
these patients, 43 patients had TCTR on both hands on different dates.
None of the hands had prior carpal tunnel release.
Interventions:
Modified percutaneous thread carpal tunnel release
under ultrasound guidance was performed on 230 hands.
Main Outcome Measures:
The Boston Carpal Tunnel Syndrome
Questionnaire.
Results:
Thread carpal tunnel release under ultrasound guidance led
to significant improvement in the short-term results, and the outcomes
were better in long-term results compared with the open or endo-
scopic release. The SupPA, Berrettini branch, and common digital
nerves were protected. There was no neurovascular complication for
any case. Significant relief of symptoms was observed 3 to 5 hours post
procedure. Most patients used their hands on the day of the procedure
for simple daily activity and most patients with office jobs were able
to return to work on postoperative day 1.
Conclusions:
The thread carpal tunnel release (TCTR)procedure has
been shown to be a safe and effective technique for carpal tunnel
release. The modified TCTR procedure minimizes postoperative com-
plications such as pillar pain, scar tenderness, or functional weakness,
by avoiding unnecessary injuries to the surrounding structures around
the transverse carpal ligament during the procedure.

Objective:
To determine if timing of initiation of outpatient physical
therapy following initial inpatient or home rehabilitation program has
an impact on range-of-motion (ROM) in patients with total knee
arthroplasty (TKA).
Design:
Retrospective, cohort study.
Setting:
Outpatient orthopedic practice.
Participants:
145 TKA patients, who had outpatient physical therapy
within 6 weeks (n
¼
91) and after 6 weeks (n
¼
54) of surgery, following
initial rehabilitation program (home or acute inpatient rehabilitation).
Interventions:
Chart review was performed to determine the range of
knee flexion and extension measured at the final clinical appointment
following TKA and the length of time to start outpatient physical
therapy following surgery.
Main Outcome Measures:
Flexion ROM and extension ROM at final
clinical appointment (mean follow-up: 8 months).
Results:
Patients who attended outpatient physical therapy within 6
week of their operation, had significantly higher mean flexion (114 vs
109 , p: 0.008) and lower mean extension (0.7 vs 1.5 , p:0.19) ROM at
their final clinical appointment, compared with those who attended
physical therapy after 6 weeks.
Conclusions:
Patients who attended outpatient physical therapy sooner
after TKA had significantly improved ROM outcomes (both flexion and
extension), than those who started later. Increased knee ROM is associ-
ated with better functional performance and better quality of life.
Rehabilitation physicians should be aware of the importance of expedient
outpatient physical therapy in maintaining knee ROM following TKA.

Objective:
To determine the sensitivity and false negative rate of MRI
and CT scan in young athletes diagnosed with spondylolysis.
Design:
Cross sectional study.
Setting:
Sports Medicine Clinic at tertiary level pediatricmedical center.
Participants:
22 young athletes (10 males, 12 females, Age 14.7 1.5
years) who were diagnosed with spondylolysis based on combination of
physical examination and single-photon emission computerized to-
mography (SPECT).
Interventions:
Not applicable.
Main Outcome Measures:
MRI and CT diagnoses of spondylolysis as
determined by a pediatric, MSK specialized radiologist.
Results:
Among the 22 athletes with spondylolysis as diagnosed by
physical exam and SPECT, the sensitivity of MRI was 59.1% (95%CIs:
54.6%, 92.1%) while false negative rate was 40.9% (95% CIs: 21.5%,
63.3%) The sensitivity of CT was 77.3% (95% CIs: 36.4%, 79.3%) while
false negative rate was 22.7% (95% CI 0.9%, 45.8%).
Conclusions:
In our study, we identified that CT is a more sensitive
imaging modality with lower false negative rate in diagnosing spon-
dylolysis in young athletes compared to MRI.
