OBJECTIVEThe skeletal Class III malocclusion often occurs in ethnic Asia population, and it is difficult to obtain an ideal results if only treated with protraction headgear (PH). However, the combined rapid palatal expansion (RPE), Edgewise Technique and PH can reach it, so the authors investigated the methods and characteristics of combined RPE, Edgewise Technique and PH in the treatment of skeletal Class III malocclusion.

METHODSFifteen patients, aged 8.5-12 years, including six males and 9 females, with skeletal Class III malocclusion and maxillary retrusion were selected for this study. Radiographs of left hand and wrist showed that all patients were at the pre-pubertal stage. The duration of treatment was nine months on average.

RESULTSThe SNA and A-ptm increased with a mean of cephalometric analysis, which showed significant difference (P < 0.05).

CONCLUSIONObvious skeletal and profile changes can be achieved with combined RPE, Edgewise Technique and PH in the treatment of early skeletal Class III malocclusion.

OBJECTIVETo develop a traction reductor for the reduction of lower limb fractures during the minimally invasive surgery and explore its safety and efficacy.

METHODSFrom February 2007 to March 2009, closed or limited open reduction plus percutaneous plate and screw internal-fixation were conducted in 34 patients with fracture of distal femur and tibia metaphysic, among which there were 3 distal femoral fractures (2 33-B, 1 33-C), 14 proximal tibial fractures (9 41-A, 3 41-B, 2 41-C) and 17 distal tibial fractures (9 43-A, 5 43-B, 3 43-C, 2 Gustilo I a), according to the Association for Osteosynthesis-Orthopaedic Trauma Association (AO-OTA) classification. Besides, closed reduction plus interlocking intramedullary nailing on tibial shaft fracture were applied in 36 patients (7 42-A, 21 42-B, 8 42-C, 2 Gustilo I a). All the 70 patients, with an average age of 37.6 years (range: 17 to 63 years) and average time before surgery of 4.7 d (range: 0.7 to 12.0 d), underwent reduction by self-designed traction reductor for lower limb fracture in the surgery. The reduction duration and C-arm fluoroscopy time were recorded. Recovery of the force line of affected limbs after surgery was determined by whether the line from anterior superior iliac spine to the interdigit between the first and second toe-web passed the patella center. And the distance from bilateral anterior superior iliac spine to medial malleolus tip as well as the difference between lower limbs were recorded to determine the recovery of length after surgery. Meanwhile, the varus-valgus and anteroposterior angulations after reduction were measured by AP and lateral X-ray.

RESULTSThe reduction duration was 12.7 min (range: 7 to 31 min); X-ray fluoroscopy time, 1.3 min (range: 0.4 to 3.0 min); length difference between both lower limbs (6.5 ± 1.1) mm; and axial alignment difference (7.0 ± 1.8) mm. The X-ray result showed that varus-valgus angle was (2.75 ± 0.16)°; and anteroposterior angulation (5.13 ± 0.51)°.

CONCLUSIONThe traction reductor for lower limb fracture could achieve satisfying fracture reduction in the minimally invasive surgery of distal femur, tibia metaphysic and tibial shaft fracture.

In a patient with a distal common bile duct stone, a fracture of the traction wire of the basket occurring during the performance of mechanical lithotripsy resulted in the impaction of the lithotripter basket with a stone. The impacted lithotripter basket combined with a fracture of the traction wire is a rare complication of endoscopic stone removal. We were able to pull the impacted basket using an Amplatz goose-neck snare inserted via the percutaneous transhepatic route, which resulted in the freeing of the entrapped stone into the dilated supra-ampullary bile duct. The fractured traction wire and basket could be safely removed by pulling the traction wire from the mouth. The present report is the first to describe the safe and effective use of an Amplatz goose-neck snare for the management of a lithotripter basket impacted with a stone and a fractured traction wire.

OBJECTIVETo observe the curative effect of self-made eccentric traction belt as a manipulative reduction tool in the treatment of the distal radial fracture.

METHODSFrom February 2011 to June 2012,62 patients with distal radial closed fractures were treated by manipulative reduction with self-made wristlet-eccentric traction belt and combined with the small splint and plaster external fixation. Among them, 59 cases were Colles fractures, 2 were Smith fractures, 1 was Barton fracture. After the reduction, lateral X-ray imaging was used to evaluate curative effect immediately.

RESULTSAll the patients obtained excellent and good reduction in standard of fractures, only 1 case didn't. According to functonal assessment of Dienst, the results were excellent in 49 cases, good in 11, fair in 1, and poor in 1.

CONCLUSIONSelf-made wristlet-eccentric traction belt as a manipulative reduction tool to treat distal radius fractures, can make fractures close to the anatomic reduction, and can significantly improve the manual reduction success rate.

OBJECTIVETo reduce the complication by transurethral vaporesection of prostate (TUVP) using adjustable urethral tractor.

METHODSOne hundred and six cases with benign prostate hypertrophy underwent TUVP and catheter traction after operation by an adjustable tractor. The results by catheter traction were compared with those by rubberized cloth paste and carbasus compression.

RESULTThe urethral stricture occurred in 2.7%, 6.7%, 30.4% of cases by the catheter traction, rubberized cloth paste and carbasus compression respectively, which had statistical significance (P <0.01).

CONCLUSIONThe incidence of urethral stricture can be reduced by catheter traction after TUVP.
