ObjectiveTo explore the effectiveness of the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments to treat acute complete acromioclavicular dislocations. MethodsBetween January 2008 and April 2012, 66 patients with acromioclavicular dislocation were treated with the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments in 32 cases (experimental group) and with the clavicular hook plate in 34 cases (control group). There was no significant difference in gender, age, injured side, the cause of injury, and the time from injury to operation between 2 groups (P>0.05). Visual analogue scale (VAS), Constant shoulder scores, and coracoid clavi-cledistance (CC.Dist) were measured at preoperation and at 2 years after operation. Signal/noise quotiem (SNQ) was measured by MRI at 2 years after operation. The operation complications were observed. ResultsThe patients of 2 groups obtained primary healing of incision. The morbidity of complication in experimental group (12.5%, 4/32) was significantly lower than that in control group (91.2%, 31/34) (χ2=40.96, P=0.00). All the cases were followed up 2.8 years on average (range, 2 to 4 years). VAS scores and CC.Dist significantly decreased at 2 years after operation when compared with preoperative values in the 2 groups (P<0.05). VAS scores and CC.Dist of the experimental group were significantly lower than those in the control group (P<0.05). According to Constant shoulder scores at 2 years after operation, the results were excellent in 19 cases, good in 11 cases, and general in 2 cases with an excellent and good rate of 93.75% in the experimental group; the results were excellent in 7 cases, good in 8 cases, general in 16 cases, and poor in 3 cases with an excellent and good rate of 44.11% in the control group; and significant difference was shown between 2 groups (t=2.30, P=0.03). SNQ was significantly lower in experimental group than in control group at 2 years after operation (t=55.03, P=0.00), indicating that ligament healing was better in experimental group than control group. ConclusionCompared with simple clavicular hook plate fixation, the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments is successful in treating acute complete acromioclavicular dislocations, with the advantages of higher ligament healing, less complication, and early improvement of shoulder functions.
ObjectiveTo investigate the feasibility and effectiveness of free popliteal artery cutaneous branch flap anastomosed with lateral tarsal artery and vein for the repair of wound on the foot and ankle by anatomical observation and clinical application. MethodsLatex was poured into the blood vessels of 8 cadavers, then perforator vessel of posterolateral upper calf was dissected, and the popliteal artery cutaneous branch flap was designed with a pedicle of 2.5 cm in length; the lateral tarsal artery of the foot was dissected, could be freed to 6 cm in length; the diameter of these vessels was measured, and the number of the accompanying veins was counted. Between March 2010 and January 2013, 13 cases of foot and ankle wounds were repaired with popliteal artery cutaneous branch flap anastomosed with lateral tarsal artery and vein. The size of flaps ranged from 6.0 cm×4.0 cm to 7.5 cm×5.5 cm. There were 11 males and 2 females, aged from 41 to 65 years (mean, 47.3 years). The causes of injury included traffic accident in 8 cases, crushing in 4 cases, and twist by machine in 1 case. The size of wounds, ranged from 5.0 cm×3.5 cm to 7.0 cm×5.0 cm. The donor sites were sutured directly. ResultsAccording to anatomical observation, the popliteal artery cutaneous branch flap was designed by using the lateral popliteal artery perforator for shaft. The vessel of the pedicle perforator flaps from the popliteal artery cutaneous branch flap matched well with the lateral tarsal artery. Clinical results: vascular crisis occurred in 2 flaps, which survived after symptomatic treatment; the other flaps survived, with primary healing of wound and incision at donor site. The patients were all followed up 5-18 months (mean, 11 months). The flap had normal color and good elasticity. Second stage operation was performed to make the flap thinner in 3 female patients because of bulky flaps. The remaining patients had no obvious fat flap. According to American Orthopaedic Foot and Ankle Society (AOFAS) score for evaluation of the ankle function at 6 months after operation, the results were excellent in 7 cases, good in 5 cases, and fair in 1 case, with an excellent and good rate of 92.3%. ConclusionFree popliteal artery cutaneous branch flap anastomosed with lateral tarsal artery and vein for the repair of wound on the foot and ankle is simple and effective. The donor site is hidden.
Objective To discuss the strategy of surgical treatment for cardiac cystic echinococcosis. Methods We retrospectively analyzed the clinical data of 26 patients diagnosed with cardiac cystic echinococcosis between February 1978 and April 2013 in our hospital. There were 11 females and 15 females at a mean age of 28.9±7.6 years ranging 8-60 years. All patients underwent endocyst-punctured cystectomy, enucleation of intact endocyst and total cyst resection. Results All 26 surgeries were successful and there was no perioperative mortality. The mean time of operation was 110±32 minutes, and the mean time of hospital stay was 8.1±2.3 days. The mean follow-up time of 22 patients was 75±11 months ranging 15-190 months. There were 4 patients who were lost to follow-up. There were three recurrences and one late death. Conclusions We should choose the proper surgical method based on the patients’ condition.There is a certain effect and a low recurrance for surgical treatment of cardiac cystic echinococcosis.
