OBJECTIVETo explore guiding role of three-column theory in manipulative reduction, small splint fixation and early rehabilitative exercises of Colles fracture.

METHODSFrom August 2011 to February 2012,47 patients with Colles fractures were treated by manipulative reduction small splinting fixation and early rehabilitative exercises under the guidance of three-column theory, including 21 males and 26 females aged from 40 to 76 years old with an average of (65.5 +/- 2.3). According to AO fracture classification, 27 patients were type A (including 18 cases with type A2 and 9 cases with type A3) and 20 patients were type C (including 10 cases with type C1, 6 cases with type C2 and 4 cases with type C3). Pain and recovery time of swelling, postoperative complications were observed and recorded, Gartland-Werley scoring system were applied for evaluate functional recovery and biomechanical analysis of wrist joint at 12 weeks after operation.

RESULTSAll patients were followed up for 3 to 9 months with average of 5 months. Pain relief time ranged from 5 to 15 d with average of (7.6 +/- 2.2) d,recovery time of swelling of opisthenar was for 6 to 13 d with an average of (8.9 +/- 1.9) d. Two patients occurred tension vesicle within 3 days after operation, but no other complications occurred. According to Gartland-Werley scoring system, 25 cases got excellent results, 18 cases good and 4 cases moderate at 12 weeks after operation.

CONCLUSIONUnder the guidance of three-column theory, treating Colles fracture by manipulative reduction, small splinting fixation and early rehabilitative exercises can reduce pain and swelling time, promote union of fracture, effectively rehabilitate wrist function, improve clinical efficacy, and fit for concept of biomechanics.

OBJECTIVETo discuss the midface aging mechanism through anatomic study of malar fat pad.

METHODS10 fresh adult cadaveric heads (20 sides) fixed by vascular perfusion of formalin were used for anatomic study with microsurgery technique under microscope. The midfacial ligament and connective tissue between skin and subcutaneous fat were observed carefully in different parts of midface. The location, shape and extent of malar fat pad was also recorded and photographed.

RESULTSThe malar fat pad has a triangle shape. The bottom is a curve along the orbicularis retaining ligament at the lower eyelid. The fat pad is extended internally to the nasolabial fold and labiomandibular fold, externally from the major zygomatic muscle end point at the malar surface to the angulus oris and submandibular edge. (2) The malar fat pad is composed of meshed fibrous tissue, with big fat particles in it. It becomes tight when being stretched in horizontal direction along nasolabial fold and loosen when being stretched in vertical direction. (3) There is tight connection between skin and fat pad, which is divided into four areas as I, II, III, IV. The areas I, II, III are strip-shaped parelled to the nasolabial fold. The area IV is a irregular quadrilateral. (4) There are six fixation ligaments between malar fat pad and deep tissue: orbicularis retaining ligament upper layer of lower eyelid, orbicularis retaining ligament substratum of lower eyelid, zygomaticus ligament, zygomatic cutaneous ligament, zygomatic cutaneous ligament substratum, platysma There are four closely connected areas cutaneous forward ligament, cheek maxilla ligament.

CONCLUSIONSbetween the facial skin and malar fat pad which makes malar fat pad and skin keep relatively consistent. The malar fat pad moving down mainly resulted from slack of ligaments support which is one of the reasons for aging face.

BACKGROUNDMany patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China.

METHODSBetween March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression.

RESULTSDuring hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non-ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary intervention (PCI) within 6 months was more common in patients with RA, P < 0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P = 0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA, P = 0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P < 0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI, 687 (59.3%) versus 114 (41.5%), P = 0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%), P = 0.006; and beta-blockers 176 (64.0%) versus 864 (74.5%), P = 0.000. Multivarible regression analysis showed that RA was associated with prior angina (OR 2.086, 95% CI 1.466 - 2.967), in-hospital PCI (OR 0.579, 95% CI 0.431 - 0.778), in-hospital congestive heart failure (OR 2.410, 95% CI 1.634 - 3.555), myocardial re-infarction (OR 7.695, 95% CI 3.701 - 15.999), beta-blocker (OR 0.626, 95% CI 0.458 - 0.855), and heparin (OR 3.411, 95% CI 1.604 - 7.382).

CONCLUSIONSIn-hospital congestive heart failure, myocardial re-infarction, prior angina history and use of heparin are stronger independent predictors of RA; beta-blockers and PCI are also important predictive factors for RA.

OBJECTIVETo analyze the pathogenic mechanism and the clinical significance of post-traumatic thoracolumbar syringomyelia through reviewing the clinical manifestations.

METHODSThe data of 15 patients (14 males and 1 female, aged from 28 to 56 years, with an average of 36 years) with post-traumatic syringomyelia treated in our hospital from December 1997 to February 2002 were studied retrospectively. Two patients suffered from T11 fractures, 7 from T12 fractures and 6 from L1 fractures. There were 12 patients with burst fractures and 3 with fracture dislocations. Anterior decompression, bone graft, bone fusion and internal fixation were made on 6 patients, posterior decompression, bone graft, bone fusion and internal fixation on 1 patient, and non-surgical treatment on 8 patients.

RESULTSSyringomyelia of the patients was diagnosed accurately with magnetic resonance imaging at 0.5-4 years after the original thoracolumbar fracture. The cavern was round in 6 cases, elliptic in 6 cases, and irregular in 3 cases. The patients also suffered from pain (80%), myodynamia attenuation in lower extremities (66.7%), aggravated spasm (46.7%), sensation loss or hypesthesia (46.7%), decreased coordinate function of lower extremities (20%) and autonomic nerve symptom (6.7%).

CONCLUSIONSPost-traumatic thoracolumbar syringomyelia should be suspected if the patient has new neurological symptoms, such as myodynamia attenuation in lower extremities, after the neural function becomes stable for certain time.
