We report a case with compression myelopathy due to proliferative changes around the C2 pars defects without instability. A 69-year-old man presented with progressive clumsy hands and spastic gait. Plain radiographs showed bilateral spondylolysis (pars defects) at C2 and fusion between C2 and C3 spinous processes. Dynamic views revealed mobility through the pars defects, but there was no appare...

OBJECTIVES To investigate shoulder rotator strength and steadiness in athletes with anterior instability and superior labrum anterior posterior (SLAP) lesion. DESIGN Cross-sectional laboratory study. METHODS Athletes with anterior shoulder instability (instability group, n=10) and a SLAP lesion (SLAP group, n=10) were compared with healthy athletes matched by age, anthropometrics and sport ...

BACKGROUND Injuries to the sternoclavicular (SC) joint typically occur with high-energy mechanisms such as those obtained in automobile accidents or contact sports. Many disorders of the SC joint can be treated nonoperatively. However, surgical treatment may be indicated for locked posterior dislocations; symptomatic, chronic instability; or persistent, painful osteoarthritis that fails nonoper...

objective : the aim of this study was to assess the amount of interdental bone in posterior areas of the mandible for placing orthodontic mini-implants to provide and control anchorage in orthodontic treatment. materials and methods : the amount of interdental bone in areas between the second premolars and first molars, first and second molars on the right and left sides of the mandible were de...

To examine the clinical outcomes and return to sport rates after treatment of combined, complete (grade III) injuries anterior cruciate ligament (ACL) medial collateral (MCL).A literature search following databases was completed using key words related combined ACL (MCL) tears: MEDLINE, Embase, Cochrane Controlled Trials Register, Database Systematic Reviews, Cumulative Index Nursing Allied Hea...

BACKGROUND Excessive pelvic tilt may be one of the factors leading to instability in total hip arthroplasty (THA), even when the acetabular cup is placed properly. To our knowledge, only a few studies have described late anterior dislocation due to posterior pelvic tilt. We present 3 cases with late anterior dislocations possibly due to posterior pelvic tilt. CASES PRESENTATIONS Case-1: An 84...

Objective: To review internal impingement of the shoulder. Design: Review article. Anatomic & Biomechanical Factors: Internal impingement is typically understood to be the impingement of the cuff on the posterior-superior labrum, with shoulder abduction and external rotation, a position seen in overhead athletes. While pinching of the cuff on the posterior labrum can be seen in normal subjects,...

Background The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the sympt...
