We describe a new surgical treatment of atrophic nonunion of the clavicle. The nonunion is excised by cuts at 45 degrees to the long axis and repair uses 3.5 mm pelvic reconstruction or dynamic compression plates, with a lag screw to provide interfragmentary compression. The site is grafted with cancellous bone. We have been successful in all seven patients, with early return to normal function...

STUDY DESIGN Repeated measures. OBJECTIVE To investigate motor control (MC) patterns of normal subjects during the low level physical load of the active straight leg raise (ASLR). SUMMARY OF BACKGROUND DATA Aberrant MC patterns, as observed with the ASLR test, are considered to be a mechanism for ongoing pain and disability in subjects with chronic musculoskeletal pelvic girdle pain. These ...

Subarachnoid block is commonly used regional anesthetic technique for patients who require surgical anesthesia for lower extremities, perineum, pelvic girdle or lower abdomen. It may be useful in patients with difficult airway or suffered from co-morbidities of severe respiratory disease. Spinal anesthesia covering the mid-thoracic level yields a contracted small intestine to provide superior s...

INDICATIONS FOR AMPUTATION Malignant disease was the indication for amputation in all cases except one, when the operation was performed for extensive persistent osteomyelitis (Table I). Amputation through the pelvic girdle was necessary in all cases because of the position of the lesion and because it offered the only reasonable hope of saving or prolonging life; in some cases there existed th...

Our understanding of early gnathostome evolution has been hampered by a generally scant fossil record beyond the Devonian. Recent discoveries from the late Silurian Xiaoxiang Fauna of Yunnan, China, have yielded significant new information, including the earliest articulated osteichthyan fossils from the Ludlow-aged Kuanti Formation. Here we describe the partial postcranium of a new primitive b...

Hyperpronation may cause malalignment of the lower extremity, frequently leading to structural and functional deficits both in standing and walking. Our aim was to study the effect of induced foot hyperpronation on pelvic and lower limb alignment while standing. Thirty-five healthy subjects were requested to remain in a natural standing position for 20s in four different modes: feet flat on the...
