Objective To improve the operation method of rupture of Achilles tendon for decreasing complication. Methods Total 39cases with closed rupture of Achilles tendon were selected in this study. Short incision was made at achilles tendon wall, reveal and anneal the broken ends, using Kirschner wire and steel-wire to make rectangle frame ,intradermic fixation of fracture away from the broken ends, then sutured ends with rarities and smoothing,functional exercise after 6weeks ankle rest position fixation. Results According to the Arner Lindholm evaluation system,the treatment outcome were excellent in 34 cases ,and good in 5cases. No complication including re-rupture skin ,tendon necrosis and infection were found after operation. Conclusion Repaired closed rupture of Achilles tendon with short incision and rectangle frame, assisted with ankle rest position fixation after operation wasa worthy way for treating closed rupture of a chilles tendon.

Objective To analyze and explore the operative effect of coraccid process basilar part fractures combined injury of ligamental structure. Methods Use ilium-fascia lata complex tissue to reconstruct coronoid process of ulna and medial collateral ligament, recoverd anterior and wall horn anatomic structure of elbow joint. Total 9 cases of ulna coracoid process fractures concomitancy with elbow posterior dislocation . Among these one with olec-ranon fracture,five patients with head of radius fracture. Anterior trance joint approach was used,removal bone chips, restore defect with ilium-fascia lata complex tissue after cuting and trimming. Once reduction was achieved,fixed with screw. Repaird the collateral ligament and anterior joint capsule use the fascia lata, If there were combined fracture of the radius head or olecranon fracture,fixed through lateral approach,All injured extremities were treated with a posterior plaster splint with functional position for 3 weeks followed by elbow rehabilitation training. Results According to Moneys evaluation method,2 patients were classified as excellent ,5 as good,l as fair and 1 as poor. The excellent and good rate was 77. 8%. Two patients with gently ossifying myositis but no patients with wound infection,internal fixation loosening or break,elbow joint destabilizing orcorpus libemm. Conclusions Coracoid process basilar part fractures was simultaneous with the instability of osteal frame and soft tissue. To attain the favourable anatomical foundation for elbow joint functional recovery, it should rebuild the height and shape of coronoid process first and think highly of repair or rebuild medial collateral ligament and joint capsule. It reconstructed the coronoid process osteal frame and soft tissue instability at the same time to use ilium-fascia lata complex tissue. The operative procedure is simplify with reliability effect and fine functional rehabilitation.

Objective To observe the application and efficacy of dynamic condylar screw (DCS) in treating intertrochanteric fractures of the femur and discuss the fixation principle, feasibility, advanta-ges and related issues. Methods A retrospective analysis was done on 23 patients with intertrochanter-ic fractures of the femur treated with DCS from January 2000 to December 2006. Of all, there were 10 elderly patients with different levels of various kinds of internal diseases and 13 young patients injuried by high-energy such as traffic accidents. According to Boyd' s classfication, there was one patient with type Ⅰ fracture, five with type Ⅱ , nine with type Ⅲ and eight with type Ⅳ. After a detailed pre-operative physical examination and targeted treatment, DCS fixation was employed for intertrochanteric fractures of the femur. Results A follow-up for average 18 months showed no death. Early complications occurred in three patients including two with pulmonary infection and one with urinary tract infection, who got cured after proper treatment. There was one patient with long-term complication, post-traumatic arthritis. All 23 patients got bone healing, with excellenee rate of 96% according to Harris criteria. There were no complications like breakage of nails, nonunion, eoxa yarn deformity, shortening or external rotation of the lower limb. Conclusions DCS has advantages of simple operation, reliable fixation and coincidence with biomechanical characteristics and hence is one of ideal methods for treatment of intertrochanteric frac-ture of the femur, especially for subtrochanteric fracture, contrary chanteric fractur, fracture involving large pyriform troehanteric and comminuted fractures of sub-trochanteric lateral os integumentale.

Objective To investigate the relationship between estrogen levels and tenosynovitis in postm-enopausal women. Methods 74 cases of postmenopausal women,including 32 cases of tenesynovitis (group A),42 cases healthy postrnenopausal women for the control group (group B) were observed. 42 cases of normal menstruation women were taken as control group (group C). Results The estrogen level was (89.7066±126.7458) pmol/L in group A,(45.6768±30.6342) pmol/L in group B,and (626.7384±361.5348)pmol/L in group C,There is statistical difference between group A and group C (P<0.05). Conclusions Tenosynovitis incidence in postmeno-pausal women has no significant relationship with the level of estrogen change.
