PURPOSE The purpose of this study was to evaluate the clinical and radiological results of total hip arthroplasty using a proximal modular femoral stem in patients who had secondary coxarthrosis associated with a dysplastic hip. MATERIALS AND METHODS Forty-two patients (45 hips) with secondary coxarthrosis were evaluated after undergoing primary total hip arthroplasty using an S-ROM proximal ...

Anatomical landmark of A1 pulley is important especially in minimal invasive surgery. The lengths and landmarks of A1 pulleys were evaluated in 510 preserved cadaver digits. The cadavers were 25 females and 26 males aged at the time of death ranged from 48 to 89 years. Measurements of A1 pulley lengths were made and used to predict the landmarks of the proximal pulley margins, which are related...

Skin biopsy as a complementary in the diagnosis of small fiber neuropathy, has came to be increasingly used by different researchers. There is a need to establish normative standards that allow the comparison of biopsies performed in patients with biopsies performed in healthy individuals in the Portuguese population. Presentation of data collected in the counts of intraepidermal nerve fibers i...

LEBER, PAUL II., AND DONALD J. MARSH. Micropuncture study of concentration and fate of albumin in rat nephron. Am. J. Physiol. !219(2) : 358-363. 1970.-Albumin concentration in various segments of the rat nephron was determined by analyzing freeflow micropuncture samples with a radioimmunoassay. The average proximal tubular fluid concentration was 3.3 mg/lOO ml but fluctuated over several milli...

BACKGROUND Little is known about oncologic outcomes of patients with primary bone tumors complicated by a pathologic fracture and treated by limb salvage. METHODS Our study included 17 men and 14 women aged 6 to 61 years (average age 17 years). All 31 patients had primary bone tumors complicated by a pathologic fracture. Diagnoses included osteosarcoma (17 patients), Ewing's sarcoma (10), mal...

BACKGROUND Checkrein ligament release for treatment of proximal interphalangeal joint Dupuytren contractures does not address the shortened arteries or deficient skin. The Digit Widget uses soft-tissue distraction to overcome these issues. This study compares checkrein ligament release after fasciectomy versus preliminary soft-tissue distraction, followed by operative release, for treatment of ...

OBJECTIVE To determine the optimal selection of proximal fusion level for degenerative scoliosis (DS) and investigate the long-term proximal-related complications. METHODS Profiles of 95 consecutive patients with DS who underwent posterior long instrumented fusion were analyzed retrospectively. Perioperative parameters were reviewed stratified into 3 groups according to the relationship betwe...

Five Macaca speciosa monkeys were trained to discriminate between the order of two tactile stimulus presentations (proximal-distal vs. distal-proximal) to the lateral calf. Psychophysical thresholds for tactile sequence recognition were obtained by varying the distance between the spots stimulated. Stabilized preoperative thresholds for stimulation on the lateral calf averaged 10.4 mm, which is...

BACKGROUND There is no consensus in the literature as to which point of the radial artery (RA) is the safest to attempt vascular access. The purpose of this study was to measure the diameter, tortuosity and branching patterns of the distal RA. MATERIALS AND METHODS 140 cadaveric RAs (66 male, 74 female) were dissected and measured. The external diameter of the RA was measured at 2 cm incremen...

INTRODUCTION Osteochondroma is a common benign bone tumor, protruding from the underlying normal bone. Osteochondromas can cause pain depending on their location and size. The pes anserinus is located at the proximal medial side of the tibia, where the tendinous insertions of the sartorius, gracilis and semitendinosus muscles collectively attach. Pes anserinus syndrome, or anserine bursitis, is...
