Shanghai Ruijin Hospital, Second Medical School Department of Orthopedics Cogo, Shanghai 200025, China) Abstract: The grinding SUI peptide backbone of the treatment of fractures to arm-type external fixation wins comminuted fractures, the method is simple, more effective. Key words: peptide backbone of the fracture; external fixation in the week Keywords: R6834l Document code: B I period from l994-1999 Application of external fixation for fracture fixation in the treatment side of the backbone of the 48 patients achieved good effect, are summarized as follows = 1 General information The clinical data of 48 patients, male 3l, female l7 down; age of l6-72 years old, average 328 years old. Delete the left side shaft fractures in 29 cases,[link widoczny dla zalogowanych], 19 down the right side; fracture site: 14 cases in the upper, middle l8 cases, the lower segment l6 cases; nonunion in 3 cases; closed fracture in 2 cases. 43 side of the open fractures. By Gu ~ tilo classification, I ° 2 cases, Ⅱ in 3 cases, Ⅲ a9 down, Ⅲ b15 cases, Ⅲ c14 cases; nerve rupture, 2 cases of radial nerve contusion, 9 cases of vascular rupture in 5 cases 2 treatment to arm-type external fixator in the forearm in supination under the conditions of the upper arm of the lateral pinning. Remote first taut skin, touch the dizzy deleted on the outside edge of condyle. If local swelling significantly obese patients or those who can make a small cut needle Ke rq; proximal needle, note the direction of the needle from outside to inside in the coronal plane; by radiography or C-arm machine confirmed after the appropriate length of needle , fixed needle, and universal joints. If Ⅲ a, Ⅲ b patients, the first for debridement, wound I period or Ⅱ, sewing table; if Ⅲ c patients, the first debridement, needle re nerves, blood vessels kiss homes, following a fixed universal joints; if nonunion patients, first for pinning, re-shortening, bone; 3 Results were followed up, Dienst scoring functions in Table 1, of the results in Table 2. Functional assessment criteria table lDienst Received Date :2001-03-23 to discuss external fixator treatment of humeral shaft fractures, the longitudinal axis can slide through. The role of extension or pressure from both ends with spherical joints can be used for parties to adjust the universal,[link widoczny dla zalogowanych], flexible, and early activities, especially with severe open comminuted humeral fracture, and the advantages more prominent. Firmly on the belly can stabilize bone fractures, but also for shortening fixed, to maintain fracture alignment, while closed reduction, without stripping the periosteum, without destroying the blood supply, blood supply to the fracture of a small, but also without a fracture to avoid fixation and fracture surface contact, thereby reducing infection. According to B e,[link widoczny dla zalogowanych], etc. 【bleed at the nose. And C, ustilo j such report, Ⅲ b, c bite patients than the use of external fixation intramedullary nail fixation of infection was significantly lower (Table 3) = In addition, lower risk of delayed bone healing, easy dressing, Ⅱ of repair are also convenient. Can be an early event and because, in order to avoid muscle atrophy,[link widoczny dla zalogowanych], joint stiffness, osteoporosis and other more difficult to thread a needle; after pinning at the proximal cause pain often due to adhesion traction, impact shoulder joint, leading to joint stiffness; surgery if improper operation may cause a radial nerve contusion; postoperative radial nerve was embedded callus caused by neurological dysfunction; stress shielding exists Symphony £ infections; winter clothing inconvenience. In response to these shortcomings, the operation should be on the dirty condyle stretch the skin at the needle, the proximal needle,[link widoczny dla zalogowanych], the attention to the upper limbs in supination, the needle in the frontal plane from outside to inside, outside to avoid shoulder surgery development activities, the deltoid muscle fibers distorted Erzhi referred pain, and the needle slightly before the muscle fiber blunt dissection, reducing adhesion opportunities; needle placed in supination when the upper limb, C-arm machine and can reduce the radial nerve guide damage opportunities.
