Background The success of hip surgery in treating acetabular retroversion depends on the severity of the structural deformity and on selecting the correct patient for open or arthroscopic procedures. Purpose To compare a group of patients with retroverted hips treated successfully with hip arthroscopy with a group of patients with retroverted hips that failed arthroscopic surgery, with specia...

OBJECTIVES To investigate the incidence, distribution and radiological characteristics of dural ossification (DO) associated with ossification of ligamentum flavum (OLF) in the thoracic spine. DESIGN A retrospective radiographical analysis. SETTING This study was conducted at a single institution in China. PARTICIPANTS 53 patients with OLF who underwent posterior decompression surgery bet...

UNLABELLED Psoriatic arthritis (PsA) is a systemic disease and cervical spine can be affected. The data regarding cervical spondylitis are very rare and diverse in literarture. The aim of study was to assess the prevalence of cervical spine involvement in patients with PsA. Between totally 41 patients with PsA we confirmed the incidence of 68% (29 patients) with symptomatic cervical spine disea...

Purpose: The ischial tuberosity, referred to as the “sit bone” by patients with pain when sitting, is surrounded by critical nerves. Depending upon how a person places weight on the ischial tuberosity, symptoms can vary from pudendal nerve symptoms, to sciatica, or to posterior femoral cutaneous nerve (PFCN) symptoms. This research relates, for the first time, the involvement of the PFCN, inclu...

the wound may be the strapping is omitted so as to allow ready access to it. An ordinary extension stirrup is applied to the leg and the foot-piece of the stirrup is fastened to a weight by means of a string passing over an ordinary reel acting as a pulley fixed in the vertical foot-piece of the splint. The thigh rests in the padded notch of the buttock-piece and the ischial tuberosity is broug...

This study aims to clarify the relationship of primate bony pelvic structure to locomotor habit. As with most of the postcranial skeleton, the pelvic bones of species within the Ceboidea and the Cercopithecoidea are remarkably similar visually except for variations in size. Yet there are substantial differences in locomotor pattern between the species in these taxa. I performed canonical analys...

We present a case of avulsion of a large fragment of the ischial tuberosity in an elderly lady, caused by an extreme abduction of the hip. To our knowledge such an injury has not yet been described in the elderly. The decision to operate was based on the reported experience with this injury in young individuals. We assumed that the same indications applied, while also taking into account the kn...

BACKGROUND Shoulder complaints, and especially the outlet-impingement syndrome, are a common condition. Among other things, poor posture has been discussed as a cause. A correlation between impingement syndrome and restricted mobility of the thoracic spine (T) has been described earlier, but there has been no motion analysis of the thoracic spine to show these correlations. In the present prosp...

An eight-year-old male Staffordshire bull terrier was presented with a bleeding mass in the urethral mucosa 1.5 cm distal to the ischial arch. After cytological findings suggestive of a squamous cell carcinoma and confirmation of the mass with urethroscopy, total penile amputation followed by transpelvic urethrostomy using an ischial symphyseal ostectomy was performed. The procedure successfull...
