ABSTRACT
Objective:To investigate the therapeutic effect of Flow-through anterolateral thigh perforator flap (ALTPF) or medial sural artery perforator flap (MSAPF) in repair of Gustilo III C wound of foot.Methods:From July 2015 to June 2021, 8 patients with Gustilo III C wound of foot were treated in the Department of Foot and Ankle Surgery of Wuxi No.9 People’s Hospital. The patients were 7 males and 1 female, aged 25-62 years old, and (45.88±12.96) years old in average. Flow-through ALTPF or Flow-through MSAPF were used to repair the defect according to the size of the wound and the length and diameter of the defect vascular. Among the patients, 6 were repaired with free Flow-through ALTPF, and 2 with free Flow-through MSAPF. The size of flap was 9 cm×5 cm-22 cm×8 cm with (115.00±46.16) cm 2 in average, and the vascular bridging was 6-12 cm in length, with (8.75±2.50) cm in average. All patients received outpatient follow-up. The appearance of the flap, blood supply of affected limb, healing of fracture and dislocation and the recovery of limb function were recorded. Maryland score was used to evaluate functional recovery. Results:The flaps survived uneventfully in all 8 patients, and the wounds in donor site healed primarily. All patients were followed-up for 6-22 months with (12.25±5.39 ) months in average. At the last follow-up, all the flaps had satisfactory contour in soft texture and blood supply without occlusion in the bridging vessels. The fractures and dislocation were healed, and the appearance and function of the foot recovered satisfactorily. The Maryland score showed excellent in 3 patients, good in 4 patients and fair in 1 patient.Conclusion:Flow-through ALTPF or MSAPF can selectively used to reconstruct the Gustilo III C wound of foot in one stage. The functional recovery of the affected limb was satisfactory and the clinical effect was good.
ABSTRACT
Objective:To analyze the predictive value of enhanced MRI in the outcome of prolapsed and sequestrated lumbar disc herniation through a retrospective analysis.Methods:A retrospective analysis of the data of 64 patients with prolapsed and sequestrated lumbar disc herniation from January 2015 to December 2018, including 38 males and 26 females; age 35.72±12.44 years (range, 22-64 years) ; 43 cases of prolapsed type, 21 cases of sequestrated type. Conservative treatment was the first choice for all patients, in case of surgical indications during the treatment, percutaneous endoscopic lumbar discectomy or fenestration discectomy will be performed. Enhanced MRI was performed at the first and last inspections, the volume of the protrusion, the thickness of rim enhancement (Tr), and the extent of rim enhancement (Er) were measured and calculated at the same time. According to the ring around the protrusion, the size of the rim-enhancement area was divided into type I-III; then compared the relationship between the rim-enhancement signal differentiation and the resorption rate of protrusions, and the correlation between Tr, Er values and the resorption rate of protrusions during the initial inspection.Results:Among the 64 patients, 42 patients completed conservative treatment, and 22 received surgical treatment. According to the rim-enhancement signal differentiation, 23 cases were treated conservatively for type I, 3 cases were treated by surgery; 16 cases were treated for type II conservatively, 7 cases were treated by surgery; 3 cases were treated for type III conservatively, and 12 cases were treated by surgery. All patients were followed up for 12 to 34 months. Among 42 conservatively treated patients, The volume of the protrusion before treatment was 2 645.67±690.86 mm 3, and the volume of the protrusion after treatment was 842.76±573.35 mm 3. The volume of protrusions before and after treatment was statistical significance ( t=11.897, P<0.001), Tr was 1.38±0.83 mm, and Er was 73.08%±34.39%, the resorption rate of protrusions was 65.10%±24.50%, and 39 cases (92.86%, 39/42) reached the standard for protrusion resorption (resorption rate ≥30%); 23 cases of type I , the resorption rate was 76.54%±18.62%; 16 cases of type II had an resorption rate of 56.81%±21.44%; 3 cases of type III had an resorption rate of 21.58%±12.19%. The resorption rate of type III were compared by single factor analysis of variance, and the difference was statistically significant ( F=12.885, P<0.001); 32 cases of both type I and II (82.05%, 32/39) had significant resorption (resorption rate ≥50%), and no case of type Ⅲ had significant resorption, comparing with type I and II, the difference was statistically significant ( P=0.010); Tr was positively correlated with resorption rate ( r=0.569, P<0.001), Er was positively correlated with resorption rate ( r=0.677, P<0.001). Conclusion:Under close clinical observation, parts of the prolapsed or sequestrated lumbar disc herniations can be conservatively treated, and the herniated disc can be resorption in many people and the clinical symptoms were alleviated. Rim-enhancement signal differentiation by enhanced MR has a better predictive value for the outcome of the herniation, type I is more prone to resorption, preferred conservative treatment, type Ⅲ is not easy to resorption, preferred surgery treatment, and the higher thickness of rim enhancement, the greater extend the rim-enhancement, the more prone to resorption phenomenon.
ABSTRACT
This paper reviewed the mechanism of Chinese herbal bathing for knee osteoarthritis. It has been found that Chinese herbal bathing worked mainly through improving bone circulation, inhibiting inflammation and promoting the progress of chondrocytes restore.In addition, the autophagy was related to the degeneration and apoptosis of chondrocytes. This paper help to provide ideas and direction for the treatment of knee osteoarthritis with Chinese herb bathing therapy.
