Desbuquois dysplasia is a severe condition characterized by short stature, joint laxity, scoliosis, and advanced carpal ossification with a delta phalanx. Studying nine Desbuquois families, we identified seven distinct mutations in the Calcium-Activated Nucleotidase 1 gene (CANT1), which encodes a soluble UDP-preferring nucleotidase belonging to the apyrase family. Among the seven mutations, fo...
Giant cell tumor of the tendon sheath (GCTTS) is the second most common benign tumor of the hand. Although bony indentation from external compression by the GCTTS is frequently seen on x-ray film, the intraosseous invasion is relatively rare and is a sign for high recurrence. We present a woman with extensive GCTTS located in the left index finger at the level of distal interphalangeal joint. X...
We present a case of empirical treatment failure for chronic osteomyelitis in a previously healthy 11-year-old male involving the distal phalanx of the right first digit. After initial debridement, empiric antibiotics were started for presumed Staphylococcus aureus infection. Operative bacterial cultures yielded no growth. Despite three weeks of antistaphylococcal antibiotics the patient's symp...
From 1987 to 1993 we treated 33 patients with 29 phalangeal and seven metacarpal fractures by external fixation using a mini-Hoffmann device. There were 27 open and 25 comminuted fractures. In 12 patients one or more tendons was involved. The mean follow-up was 4.4 years. Complications occurred in ten fractures; two required repositioning of the fixator. All the fractures healed. The functional...
Objective: To report defection of phalanx under the reconstructed pulleys with Bunnell’s technique. Methods: We followed up 26 reconstructed annular pulleys in 23 digits of 18 cases for 20 months and analysed the X-ray results of those phalanges. The function of pulley reconstruction was observed. The joint flexion and extension movement of the finger joint was recorded. Results: All the recons...
The harmonic index of a graph $G$, denoted by $H(G)$, is defined asthe sum of weights $2/[d(u)+d(v)]$ over all edges $uv$ of $G$, where$d(u)$ denotes the degree of a vertex $u$. Hu and Zhou [Y. Hu and X. Zhou, WSEAS Trans. Math. {bf 12} (2013) 716--726] proved that for any bicyclic graph $G$ of order $ngeq 4$, $H(G)le frac{n}{2}-frac{1}{15}$ and characterize all extremal bicyclic graphs.In this...
Figure 1. Radiographs of the left hand with an expansile lytic lesion within the midshaft of the ring finger proximal phalanx with endosteal scalloping and thinning of the surrounding cortex.
osteoid osteomata are rarely found in the distal phalanges of the hand. the usual presenting features are chronic pain, nail enlargement and increase in size of the terminal part of the digit. diagnosis is difficult but surgical excision is effective for treating the patients’pain. we reported this tumor in distal phalanx of the middle finger.
dxl of calcaneus is a portable method for bmd. this study determined a cut off point for dxl in osteoporosis diagnosis. in 510 healthy postmenopausal women, bmd of axial regions with dxa (dpx-md, ge,lunar corp, madison, wi) and heel with dxl (demeteck- sweden), measured. the agreement of two methods and cut off point for dxl in defining osteoporosis, obtained. dxa found osteoporosis in 34.3% an...
