OBJECTIVETo research the efficacy,security and necessity of combined therapy for preventing postsurgery stiffness after elbow fracture.

METHODSFrom May 2009 to April 2010, 60 patients with elbow fractures treated by operation were randomly divided into two groups: combined therapy group and past procedure group. Thirty patients in the combined therapy group,including 12 males and 18 females, ranging in age from 23 to 63 years, averaged (43.53 +/- 7.74) years old; 15 patients had two parts fractures, including humeral intercondylar fractures combined with olecroanon and (or) ulna coronoid process fractures in 8 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 3 cases, fractures of olecroanon and ulna coronoid process in 3 cases, fractures of olecroanon and capitulum radius in 1 case; other 15 patients had one part fractures, including fractures of exterior or interior humeral condyle in 8 cases,fractures of olecroanon or ulna coronoid process in 6 cases, fractures of capitulum radius in 1 patient. Thirty patients in the past procedure group,including 11 males and 19 females, ranging in age from 24 to 67 years, averaged (46.13 +/- 6.22) years; 15 patients had two parts fractures, including fractures of humeral intercondylar fracture combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 2 cases,fractures of olecroanon and ulna coronoid process in 5 cases,fractures of humeral intercondylar fracture combined with capitulum radius in 1 patient; 15 pa- tients had one part fracture, including fractures of exterior or interior humeral condyle in 6 cases, fractures of olecroanon or ulna coronoid process in 8 cases, fractures of capitulum radius in 1 patient; the patients in the past procedure group were treated with past procedure methods. Mayo Elbow Performance Score (including gmotion of elbow joint) and security (using X-ray to recheck displacement fracture, internal fixation failure and heterotopic ossification) were evaluated at postoperative 6 months. From 2002 to 2006, 30 patients were reviewed as historical control group, including 17 males and 13 females, ranging in age from 27 to 62 years, averaged (47.17 +/- 7.83) years; 15 patients had two parts fractures, including fractures of humeral intercondylar combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 1 case, fractures of olecroanon and ulna coronoid process in 6 cases, fractures of ulna coronoid process and capitulum radius in 1 case; 15 patients had one part fractures,including fractures of exterior or interior humeral condyle in 9 cases, fractures of olecroanon or ulna coronoid process in 5 cases,fractures of capitulum radius in 1 case. The Mayo Elbow Performance Score of the patients in historical control group was evaluated retrospectively at postoperative 6 months and the results were compared with that of past procedure group.

RESULTSMayo score of combined therapy group was (91.00 +/- 7.81)surpassed to (76.83 +/- 10.71) of the past procedure group and (73.17 +/- 1.99) of historical control group (F = 24.98, P < 0.05). The range of motion of elbow was (102.40 +/- 9.16) degrees of combined therapy group surpassed to (83.57 +/- 6.21) degrees of the past procedure group (t = 9.325, P < 0.05). There were no internal fixation loose,obvious fracture displacement and heterotopic ossification in each X-ray examination of patients in the combined therapy group. The Mayo score of historical control group was (73.17 +/- 11.99), showing no significant differences when compared with (76.83 +/- 10.71) of the past procedure group (LSD, P = 0.172).

CONCLUSIONCombined therapy including different stage, different method combination and different subject to practice to prevent postsurgery stiffness after elbow fracture is effect, security and necessity.
