To create a novel kind of orthosis to correct the dysfunction of antebrachium, wrist, metacarpus and digit and to facilitate the protection and functional training after injury of forearm and hand. The orthosis is constituted of a cardinal shelf, a stem shelf of metacarpophalangeal joint, a front bracket, finger ferrules, elastic strings and steel wires. The cardinal shelf is composed of a backplate for dorsal palm and a bracket for wrist with a U-shaped rack fixed in front of it. Ferrules of index finger, middle finger and fourth finger and little finger are connected to the backplate on the cardinal shelf through elastic strings. The thumb ferrule is set outside the ferrule of index finger on the backplate with steel wires. Another ferrule that is used to enclose the wrist and antebrachium is linked to the crossbar of the U-shaped rack through elastic strings. This orthosis plays an effective role in the protection of nerves, tendons, extremity of vascular anastomosis and the prevention of allotopia after fracture due to different trainings. It can improve the range of motion of wrist joint, metacarpophalangeal joint, and articulationes interphalangeae and strengthen the muscle power of pronator teres, pronator quadratus, supinator, wrist extensor, wrist flexor, extensor digitoium, perforans manus and musculus flexor digitorum sublimes. This orthosis could be applied for patients after the operation of antebrachium,wrist and manus to promote the recovery of their functions.

AIM: To introduce a new kind of wrist-hand orthosis.METHODS: The major frame of wrist-hand orthosis is composed of dorsal carpal guard plate and carpal bracket; while, a U-shaped anterior bracket is fixed on the anterior side of the major frame. Ferrules of index finger, middle finger, fourth finger and little finger respectively connect to dorsal carpal guard plate of the major frame via elastic brace; ferrule of thumb is fixed on one side of ferrule of index finger by using steel wires; an abduct elastic sleeve is designed on the lateral dorsal carpal guard plate of ferrule of little finger by using steel wires. According to experimental demands, wrist with the palms upward or downward puts into the major frame, which is composed of dorsal carpal guard plate and carpal bracket. The hand is anterior to the major frame; ferrules are located over rolling sleeve by forward and fingers are located below the rolling sleeve by forward; ferrules are respectively rang the index, middle, fourth and little fingers; ferrule of thumb is rang the thumb. Continuously, wrist rotates based on orthopaedic demands to realize various orthopaedic functions.RESULTS: The wrist-hand orthosis is used to help the hand maintain extension after extensor tendon injury operation in order to restrict active areas of fingers and promote healing of injured side. On the other hand, this new orthosis is also used to help wrist joint and digital joint maintain flexion after extensor tendon injury operation in order to improve flexion and extension of wrist joint, enlarge active area of flexion of wrist joint, enlarge drifting active area of radialis of wrist joint, and increase muscle strength of radial flexor muscle, ulnar flexor muscle, extensor carpi radialis muscle, extensor carpi ulnaris muscle, extensor carpi ulnaris muscle, flexor carpi ulnaris muscle, extensor digitorum communis muscle, superficial flexor muscle and deep flexor muscle.CONCLUSION: The wrist-hand orthosis refers to protection of wrist and hand after operations of nerve, tendon, muscle and vessel injuries and recovery of motor dysfunction of wrist joint and digital joint induced by wrist-hand fracture; on the other hand, this new orthosis can improve active area of wrist joint and strengthen muscle force.

Capillary leak syndrome (CLS) is a common and life-threatening disorder in children.The common pathogenies are sepsis,severe trauma,shock,asphyxia,extracorporeal circulation,ischemical reperfusion injury and so on.It is characterized by shock resulting from leakage of plasma,which is refected by accompanying hemoconcentration,hypoalbuminemia and edema,sometimes followed by multiple organ dysfunction syndrome.Clinicians should consider the diagnosis in patients with unexplained edema and hypotension.To know the pathophysiology and clinical course will be benefit to proper medicine choosen.

Objective To investigate the clinical effect of the MBT straight wire technique for treatment of angle class Ⅱ 1 patho-occlusion.Methods 62 cases of adult class Ⅱ division 1 patients were randomly divided into the observation group (32 cases) and the control group (30 cases).The observation group was treated with MBT straight wire appliance therapy,the control group received the traditional straight wire appliance therapy.The two groups were given cephalometric film before and after treatment,and the clinical effect was observed and recorded.Results In the observation group,there were no significant differences in SNA,SNB,ANB,LI-MP,MP-SN after treatment compared with before treatment (t =0.46,0.73,0.24,1.05,P ＞ 0.05),while there were statistically significant differences in ANB,U1-SN,U1-L1 after treatment compared with before treatment (t =1.58,6.32,7.43,P ＜ 0.05).Before treatment 7 mm of openbite,OB 2 mm after treatment,returned to normal overbite and overjet,there was statistically significant difference(t =3.26,P ＜ 0.05).The mean treatment time was (22.0 ± 2.5) months in the observation group,it was significantly lower than(3 1.0 ± 3.8)months in the control group,there was statistically significant difference (t =7.47,P ＜ 0.05).After treatment,U1-SN,U1-L1 and OB in the observation group were significantly better than those of the control group,there were statistically significant differences(t =5.47,3.43,5.41,1.67,all P ＜ 0.05).Conclusion MBT straight wire appliance has the advantages of simple operation,accurate positioning of teeth,simplified correction procedure and short treatment time,it is worth the clinical promotion.
