Vitamin D hydroxylation-deficient rickets type 1A (VDDR1A) is an autosomal recessively-inherited disorder caused by mutations in CYP27B1 encoding the 1α-hydroxylase enzyme. We report on a female patient with VDDR1A who presented with hypocalcemic seizure at the age of 13 months. The typical clinical and biochemical features of VDDR1A were found, such as hypocalcemia, increased alkaline phosphatase, secondary hyperparathyroidism and normal 25-hydroxyvitamin D3 (25(OH)D3). Radiographic images of the wrist showed metaphyseal widening with cupping and fraying of the ulna and distal radius, suggesting rickets...

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate. The lunate fracture commences at the point the lunate cantilevers over the edge of the distal radius, and then takes on the shape of the radius. We postulate that the stress fracture violates the parallel veins of the venous subarticular plexus-leading to localized venous hypertension and subsequent ischemia and edema of the fatty marrow...

Background Although proximal fibular flaps have been widely applied in wrist arthroplasty, controversy remains regarding which side of the proximal fibula is better for reconstruction of the distal radius. If the articular surface of the proximal fibula shows dorsal tilting, the ipsilateral (right) proximal fibula should be harvested in right wrist arthroplasty because the articular surface of the distal radius normally has volar tilt. This study investigated anatomical similarities between the proximal fibular articular surface and the distal radius articular surface based on morphologic analysis of the proximal fibula using computed tomography (CT)...

BACKGROUND AND OBJECTIVES: Recently, the osteoporosis treatment has attracted attention, and several drugs have been developed. Among these, bisphosphonates (BPs), parathyroid hormone (PTH) and anti-receptor activator of nuclear factor kappa B ligand (RANKL) monoclonal (MAb) denosumab (DMAb) are the major osteoporosis agents. Several studies demonstrated that the effect of osteoporosis agents is evaluated by lumar or hip dual energy X-ray absorptiometry (DXA). However, private clinic commonly use the radial DXA...

BACKGROUND: A die-punch fracture is a depression fracture of the lunate fossa of the distal radius. We propose a morphological classification of die-punch fractures that includes five types: center depression fractures, vertical depression fractures, volar depression fractures, dorsal depression fractures, and double die-punch fractures. METHODS: The radiographs of 112 die-punch fractures treated between January 2005 and January 2015 were retrospectively reviewed...

Restoration of the euparathyroid state is associated with improvement of bone dynamics both in hypoparathyroidism and primary hyperparathyroidism. To date, no study has directly compared these two groups following correction of parathyroid hormone excess or deficiency. The study was designed to investigate changes in bone mineral density and trabecular bone score with restoration of the euparathyroid state by parathyroidectomy in primary hyperparathyroidism or recombinant parathyroid hormone [rhPTH(1-84)] replacement in hypoparathyroidism...

INTRODUCTION: Although fragment specific fixation has proved to be an effective treatment regime, it has not been established how successfully this treatment could be performed using fluoroscopy and what the added value of arthroscopy could be. Establish gap and step-off distances after in intra-articular distal radius fractures that have been treated with fragment specific fixation while using fluoroscopy. MATERIAL: Forty-four patients with an intra-articular distal radius fracture were treated with fragment specific fixation while using fluoroscopy...

Lunotriquetral (LT) synchondrosis is an uncommon variant of congenital LT coalition. Unlike complete LT fusions, this incomplete pseudoarthrosis-like coalition can become symptomatic. Surgical LT arthrodesis is a described treatment for this variant of LT coalition (Minnaar type I). We report 4 patients who underwent LT fusion with a second-generation headless compression screw and distal radius cancellous autograft. Fusion was achieved in all cases at an average of 2.5 months postoperatively. All the patients were satisfied with complete pain relief in 2 patients and minimal pain in 2 patients, and all improved their range of motion...

The treatment of impacted distal radius fractures is complex. Internal fixation by a dorsal approach with arthrotomy should be considered, particularly when the fractures are dorsally comminuted. This was a retrospective, observational study of 26 patients operated between 2008 and 2012 who were reviewed in September 2013. In the surgical procedure, a single dorsal incision was made over the distal radius and arthrotomy performed; the fracture site was stabilized with two 2.4mm locking plates. The average follow-up was 39months...

Secular change in height has been extensively investigated, but size and shape of the postcranial skeleton much less so. The availability of large, documented collections of nineteenth- and twentieth-century skeletons makes it possible to examine changes in skeletal structure over the past 150 years. We examined secular changes in long bone lengths and proportions, their allometric relationship to stature, and crosssectional properties of long bone shafts. Bone measurements and stature were organized into 10-year birth cohorts, ranging from 1840 to 1989...

Estrogen deficiency associated with menopause is accompanied by an increase in the rate of bone remodeling and the appearance of a remodeling imbalance; each of the greater number of remodeling transactions deposits less bone than was resorbed resulting in microstructural deterioration. The newly deposited bone is also less completely mineralized than the older bone resorbed. We examined whether breastfeeding, an estrogen deficient state, compromises bone microstructure and matrix mineral density. Distal tibial and distal radial microarchitecture were quantified using high-resolution peripheral quantitative computed tomography in 58 women prior, during and after breastfeeding, and in 48 controls during one to five years follow-up...

: In this cross-sectional study of 45 patients with myeloproliferative neoplasms, we found no evidence of secondary osteoporosis. INTRODUCTION: Patients with essential thrombocythemia (ET) and polycythaemia vera (PV) are at increased risk of fractures but the underlying mechanisms have not been settled. We conducted a study to assess bone mineral density, microarchitecture, estimated bone strength and global bone turnover in 45 patients with ET or PV. METHODS: Patients were evaluated in a cross-sectional study with dual energy X-ray absorptiometry (DXA) at the hip and spine; high-resolution peripheral quantitative computed tomography (HR-pQCT) at the distal radius and distal tibia; and biochemical markers of bone turnover including pro-collagen type 1 N-terminal pro-peptide, osteocalcin, C-terminal cross-linking telopeptide of type 1 collagen and bone-specific alkaline phosphatase...

SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis), a rare inflammatory disorder, is an association of distinct skin disorders with pustules with osteoarticular inflammation. Its etiology remains unclear, and various treatment regimens frequently fail to control the disease. An 18-year-old male patient presented to the outpatient department with severe nodulocystic acne on the face with pain at both the wrists and lower back associated with high-grade fever and chills. On physical examination, he had severe tenderness at both wrist joints and lower back, along with swelling of right wrist...

PURPOSE: Increased ulnar variance has been shown to lead to diminished load borne by the distal radius. The purpose of this study was to determine the correlations among ulnar variance, bone mineral density, and load to failure at the distal radius. METHODS: Posteroanterior radiographs and computed tomographic scans were taken of 12 cadaveric forearms in neutral rotation. Ulnar variance was measured for each wrist by the method of perpendiculars. Measurements of cortical, trabecular, and combined bone density were made at the distal radius...

Athletic individuals may differ in body segment inertial parameter (BSIP) estimates due to differences in body composition, and this may influence calculation of joint kinetics. The purposes of this study were to 1) compare BSIPs predicted by the method introduced by de Leva(1) with DXA-derived BSIPs in collegiate female soccer players, and 2) examine the effects of these BSIPs estimation methods on joint moment and power calculations during a drop vertical jump (DVJ). Twenty female NCAA Division 1 soccer players were recruited...
