The mayaguana triad of the Drosophila repleta species group includes D. mayaguana, D. straubae, and D. parisiena, the latter two of which are very similar when examined morphologically. Many morphological characters used to define these taxa are quantitative and overlap substantially among some forms--it is only through suites of such characters that species can be identified. We apply Populati...

background: to determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves.   methods: all adolescent idiopathic scoliosis (ais) patients included in the study were classified according to lenke and king classification. the fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of t1 an...

 Abstract A 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. The cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. The most important physical finding which...

Hallux valgus deformity is a very common pathological condition which commonly produces painful disability. It is characterised as a combined deformity with a malpositioning of the first metatarsophalangeal joint caused by a lateral deviation of the great toe and a medial deviation of the first metatarsal bone.Taking the patient's history and a thorough physical examination are important steps....

OBJECTIVE To investigate: (a) associations between the direction of scoliosis, direction of pelvic obliquity, direction of windswept deformity and side of hip subluxation/ dislocation in non-ambulant people with cerebral palsy; and (b) the lateral distribution of these postural asymmetries. DESIGN Cross-sectional observational study. SETTING Posture management services in three centres in t...

Pes cavus is an increase of normal plantar concavity, where the anterior and posterior weight-bearing areas of the foot are brought closer together. A wide spectrum of foot deformities includes a plantarflexed first ray, forefoot pronation and adduction, and hindfoot varus or high calcaneal pitch.1,2 Cavovarus deformity can be classified according to the severity of malalignment ranging from a ...

BACKGROUND The precise etiology of cam impingement continues to be incompletely understood. The prevailing hypothesis posits that the deformity arises as a developmental injury prior to skeletal maturation. There is a possible evolutionary role, with an aspherical femoral head affording upright humans better stability. We set out to identify the antiquity of the cam deformity to better understa...

background & importance: spinal deformity is one of the most common disorders among the vertebral diseases that results from unnatural curvatures of spine, such as scoliosis and kyphosis. spinal fusion surgery used most commonly to treat certain types of spinal deformity. here in, we report the efficacy of posterior spinal fusion accompanied by instrumentation in patients with the limitations o...
