Prospective evaluation of smoking on clinical outcome after lumbar decompression and fusion

Hongxing Jiang

388

1yr / 6mos

Smoking associated with worse baseline clinical profile and lesser degree of improvement overtime as compared with non-smoking status.

A Comparison of Gene Modified Bone Marrow Mesenchymal Stem Cells and Commercially Available BMP (specifically BMP-2) for Spinal Fusion

First Affiliated Hospital of Soochow University

In vitro (rats)

n/a

Stem cells carrying BMP-2 induced spinal fusion vs stand alone BMP-2 protein. Note stem cells used lentivirus vectors encoding BMP-2.

Adult Scoliosis Operative vs. Non-Operative Outcomes

Gang Li

76

2 yrs

Operative cohort reported better outcomes as measured by EQ5D index, EQ5D VAS, SRS-22. SF-12 PCS outcome not significant.

Cementless Hip Stem Fixation - 20 Years of Experience

Richard Rothman

n/a (discussion)

“20” yrs

Equivalent pain relief and function restoration compared to cemented hip. < 1% failure rate at 10yrs.

Human embryonic stem cells promoted tendon regeneration

n/a (translation)

in vitro and ectopic in vivo tendon tissue

Cells viable at the tendon wound site > 4 wks after implantation.

Demonstrated safe and practical potential strategy of stepwise differentiation for tendon regeneration.

Multipotency of annulus fibrosus cells a possible role in the pathogenesis of intervertebral disc

degeneration?

Xinlin Yang

In vitro cultured non-degenerative discs of adolescent patients (removed during scoli surgery)

n/a

Potential link of situ differentiation of native annulus fibrosis cells to pathogenesis of disc degeneration.

Total knee arthroplasty (TKA) for Asian population

n/a (translation)

n/a (discussion)

n/a (discussion)

TKA system and operative technique should consider potential anatomic differences (tibial articular surface, lateral bowing of the femoral shaft, etc.).

Results after medial-pivot knee replacements (medial-pivot concept aims to emulate physiological knee kinematics)

Cheng-Yu Fan

58

> 5yrs

The Knee Society score improved from 30.5 to 91.1, and the functional score from 36.7 to 82.3. Avg ROM was 115.4. Two minor complications.

Arthroscopic PCL reconstruction using posterior trans-septal portal

Jin Hwan Ahn

97

~4yrs

Improved pain and function scores. This portal provides excellent visualization, proper tibial tunnel positioning and preserving the remnant bundle of the PCL and eniscofemoral ligament.

Meniscal repair survey

Pascal Christel

Literature review

>2 yrs

After 2 years, whatever the technique or implant, the clinical success rate following meniscal repair varies between 71.5% and 95%. There is no clear established superiority of one particular device.

Treatment of complicated fractures of lower extremity with the Ilizarov’s procedure. Minimal invasive fixation technique and callus distraction

Chuan-mu Chen

70

1-10 yrs

Distraction osteogenesis by Ilizarov’s technique is effective for restoration of limb alignment & length under poor biological conditions due to its minimal invasive fixation technique.

Arthroscopic All-inside Meniscal Repair

Jin Hwan Ahn

140 patients evaluated with 2nd-look arthroscopy

1-11 yrs

84% complete healing, 12% incomplete healing and 3% failure.

Necessity of Combined Surgical Procedures for Total Ankle Arthroplasty

Hong-Geun Jung

16

1-4 yrs

Adjunctive combined surgical procedures are necessary in addressing ankle arthritis with total ankle arthroplasty.

A Randomized Controlled Trial Comparing a Flexible Corrective Brace Vs Rigid Brace for Adolescent Idiopathic Scoliosis

Tsz Ping Lam

n/a

5 yrs

The flexible corrective brace less favorable for curve control when compared with rigid brace.
