OBJECTIVE To compare the prevalence of spinal deformities and low back pain (LBP) in adolescent competitive swimmers and normal controls. STUDY DESIGN This was a cross-sectional study with convenience sample of 112 adolescent competitive swimmers (62 females) compared with 217 students (106 females) of the same age (12.5 years). We designed a questionnaire to collect data on LBP and measured ...

Over a period of three years four girls and two boys presented with discitis. All were less than 5 years old at presentation, and each had a short history of symptoms. Three were initially thought to have pathological defects of the abdomen. All children showed abnormal posturing with exaggerated lumbar lordosis. Diagnosis was essentially clinical. All cultures were sterile. The erythrocyte sed...

BACKGROUND The restoration of disc space height (DSH) is essential in anterior lumbar interbody fusion (ALIF), while it is unclear whether the reduction of DSH may alter the mechanical status and adversely affect adjacent segment, and few literatures focused on the subject. METHODS Ninety five patients who had undergone ALIF for degenerative disc disease at our institution between March 2004 ...

Background Saggital balance is an important factor in postural alignment that has been linked to back pain, dysfunction and quality of life. It is reportedly even more important than coronal curve values. The Scoliosis Research Society (SRS) has recently proposed saggital balance threshold values for evaluating saggital vertical axis (SVA) and lumbopelvic compensations as defined by pelvic inci...

Effects of intrastriatal injections of haloperidol (Dopamine antagonist) and D-amphetamine (Dopamine agonist) on lordosis behaviour were studied in ovariectomized female albino rats, after priming with subcutaneous injections of estrogen and progesterone. The lordosis quotient (LQ) significantly increased after haloperidol, and decreased following D-amphetamine treatment. However, the inhibitor...

BACKGROUND No studies have been published on an astronaut population to assess the effectiveness of countermeasures for limiting physiological changes in the lumbopelvic region caused by microgravity exposure during spaceflight. However, several studies in this area have been done using spaceflight simulation via bed-rest. The purpose of this systematic review was to evaluate the effectiveness ...

STUDY DESIGN Retrospective study. OBJECTIVE To compare the long-term outcomes of correction surgery for Lenke 1A scoliosis patients among those with non-Substantially Touched Vertebra (nSTV), nSTV+1, or STV selected as lowest instrumented vertebra (LIV). SUMMARY OF BACKGROUND DATA Previous studies have documented good outcomes when last touching vertebra (LTV) was selected as LIV; however, ...

BACKGROUND With age, the body posture undergoes involutional changes. It is not possible to determine accurately the beginning of these changes. They begin between 40 and 50 years of age, and their slow progress increases after 60 years of age. The aim of this study was to assess the body posture of women and men over 60 years of age. MATERIAL AND METHOD Seventy people over 60 years old (35 w...

Study Design Retrospective case series. Objective StaXx XD (Spine Wave, Inc., Shelton, CT, United States) is an expandable polyaryl-ether-ether-ketone (PEEK) wafer implant utilized in the treatment of lumbar degenerative disease. PEEK implants have been successfully used as interbody devices. Few studies have focused on expandable PEEK devices. The aim of the current study is to determine the r...

A major sequelae of lumbar fusion is acceleration of adjacent-level degeneration due to decreased lumbar lordosis. We evaluated the effectiveness of 4 common fusion techniques in restoring lordosis: instrumented posterolateral fusion, translumbar interbody fusion, anteroposterior fusion with posterior instrumentation, and anterior interbody fusion with lordotic threaded (LT) cages (Medtronic So...
