OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

OBJECTIVETo study the therapeutic efficacy of manipulative reduction and percutaneous pin fixation for the treatment of severely displaced distal tibial fractures in children.

METHODSFrom May 2009 to December 2012,56 children with severely displaced distal tibial fractures were analyzed, who had been treated with manipulative reduction and percutaneous pin fixation. Preoperative fractures were confirmed as severely displaced fractures by X-ray apparatus. There were 33 boys and 23 girls,ranging in age from 3 to 14 years, with an average of 10.1 years. All the fractures were closed without vascular or nerve injuries. According to the bone fracture type, under C-arm fluoroscopy, functional reduction was achieved by manipulative reduction. The fractures were fixed with percutaneous pins. Postoperative X-ray confirmed the functional reduction. Follow-up indexes were recorded: intra-operative and postoperative complications,postoperative radiographic examination, lower extremity length and range of ankle motion. Ankle score system of Teeny was used to evaluate ankle function.

RESULTSAll the patients were followed up, and the duration ranged from 3 to 46 months, with an average duration of 19.4 months. According to the Teeny score standard, 35 patients got an excellent result, 7 good and 3 fair. Pin track reaction was found in 4 cases. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. All the patients could participate in the normal physical activities, having a normal range of motion and excellent strength of the ankle joint.

CONCLUSIONThe method of manipulative reduction and percutaneous pin fixation is a safe and convenient treatment for severely displaced distal tibial fractures in children. It has several advantages as follow: micro-trauma, tiny tissue damage, firm fixation, and the patients can exercise the function of ankle early, suggesting that it is an effective treatment method.

OBJECTIVETo study the clinical effect of the Gartland III humerus supracondylar fractures in children by manipulative reduction and Kirschner wire percataneous internal fixation.

METHODSFrom July 2010 and July 2013, 60 patients with Gartland III humerus supracondylar fracture were selected and divided into treatment group and control group. In the treatment group 32 patients were treated with traditional bone setting tetradeca-manipulative reduction and percataneous Kirschner wire internal fixation,included 18 males and 14 females with an average age of (7.8 +/- 2.7) years old ranging from 5 to 11; in the control group 28 patients were treated with open reduction and Kirschner wire internal fixation,included 16 males and 12 females with an average age of (7.2 +/- 3.0) years old ranging from 4 to 12. The motion range of the elbow joint,the time of fracture clinical healing, and the effect after 6 months of Flynm clinical functional assessment standards were observed and compared.

RESULTSThe average fracture healing time of the control group (5.01 +/- 0.43) weeks was longer than that of the treatment group (4.29 +/- 0.29) weeks (t = 7.49, P = 0.00). At 6 months after treatment,the elbow motion range of the treatment group (146.02 +/- 2.28) was more than that of the control group (140.76 +/- 4.42) (t = -5.67, P = 0.00). At 6 months after treatment, according to Flynn evaluation, in the control group,there were 7 cases as excellent, 16 as good, 4 fair, 1 poor; in the treatment group, excellent in 21, good in 9, fair in 2 (U = 3.09, P = 0.002).

CONCLUSIONManipulative reduction and Kirschner wire percataneous internal fixation for treatment of children's Gartland III humerus condyle fractures can shorten fracture clinical healing time and the clinical curative effect is better.

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

OBJECTIVETo compare therapeutic effects between Kirschner tension band fixation (TBF) and clavicular hook-plate (CHP) for treating acromioclavicular dislocations of Allman Grade III.

METHODSFrom Jan. 1995 to Dec. 2007, a total of 39 patients who were diagnosed as acromioclavicular joint dislocation of Grade III were treated with Kirschner tension band fixation (TBF 18 patients, 12 patients were male, 6 patients were female, mean age were (27.50 +/- 12.76) years old, average fixation duration were (4.28 +/- 1.27) months) and clavicular hook plate fixation (CHP 21 patients, 18 patients were male, 3 patients were female, mean age were (34.76 +/- 12.39) years old, average fixation during were (8.29 +/- 1.49) months). All the patients were followed up with a mean period over 4 years. The therapeutic effects of the two groups were compared base on complications, Karlsson scores and re-subluxation.

RESULTSThe average period from injury to fixation removal was (4.28 +/- 1.27) and (8.29 +/- 1.49) months in TBF and CHP groups respectively, comparison between the two groups, t = -8.951, P < 0.01, there was statistical difference, and the course of disease in TBF group was shorter than that of CHP group. Five patients in TBF group and 1 patient in CHP group had complications (P = 0.077 > 0.05), as well as 3 patients in TBF group and 1 patient in CHP group had re-subluxation (P = 0.318 > 0.05). Karlsson evaluation results:in TBF group, 15 patients got a grade A result, 3 grade B and 0 grade C; and in CHP groups above data was 20, 1 and 0 respectively (P = 0.530 > 0.05). There was no statistical differences between the two groups in evaluation outcomes.

CONCLUSIONThe two fixation methods are all effective methods to treat Grade III acromioclavicular dislocation of Grade III, and the long-term outcome is satisfactory.
