Objective?To compare the double dorsal phalangeal flap (DDPF) with the combination of digital neurovascular island flap (NVIF) and first dorsal metacarpal artery flap (FDMA) in terms of repairing digit degloving injury.?Methods?From October 2005 to March 2008, DDPF was used to repair 9 patients (9 fingers) with degloving injury of the thumb and index finger and completely amputated thumb and index finger (group A). From August 1996 to June 2007, NVIF and FDMA were used to repair 13 patients (13 fingers) with the thumb degloving injury and completely amputated or necrotic thumb (group B). In group A, there were 7 males and 2 females aged 19-48 years old, there were 4 cases of thumb and index finger degloving injury repair and 5 cases of completely amputated thumb and index finger reconstruction, the skin defect ranged from 6.0 cm × 3.5 cm to 7.0 cm × 4.5 cm, and the interval between injury and operation was 3-10 hours. The size of DDPF harvested during operation was 4.0 cm × 3.5 cm-5.0 cm × 4.0 cm. In group B, there were 10 males and 3 females aged 18-50 years old, there were 5 cases of thumb degloving injury repair and 8 cases of completely amputated or necrotic thumb reconstruction, the skin defect ranged from 6.0 cm × 3.0 cm to 7.0 cm × 4.5 cm, and the interval between injury and operation was 3 hours-5 days, and the size of NVIF and FDMA harvested during operation was 3.5 cm × 3.0 cm-5.0 cm × 4.0 cm. The donor site was repaired with the full-thickness skin graft.?Results?All the flaps survived uneventfully except for 1 case in group A suffering from venous crisis 1 day after operation and 2 cases in group B suffering from FDMA artery crisis 4-12 hours after operation. Those flaps survived after symptomatic treatment. All the wounds healed by first intention. All patients in two groups were followed up for 1-12 years (average 3.2 years). All the donor sites were normal except for 3 cases in group B suffering from flexion contracture deformity of the proximal interphalangeal joint due to the scar contracture in the margin of NVIF donor site. According to Allen test, the skin temperature and color of the donor fingers in two groups were normal under room temperature; 1 case of group A and 6 NVIF donor fingers of group B were pale and cold under ice water. According to sensory recovery evaluation system, 16 fingers in group A were graded as S4, 1 as S3+, and 1 as S2; while in group B, 3 NVIF fingers were graded as S3, 6 NVIF fingers as S2, 4 NVIF fingers as S1, and 13 FDMA fingers as S4. The appearance of the recipient flap was satisfactory and the color was similar to the surrounding skin. The skin temperature and color of the flaps in two groups were normal under room temperature; 2 cases of group A and 4 recipient fingers of group B were pale and cold under ice water. In group A, all the palmar flap of the recipient finger achieved the reorientation of the recipient flap sensation; while in group B, 8 cases achieved the reorientation of the recipient flap sensation, and 5 cases had double sensation. For the two-point discrimination of the flap, group B was superior to that of group A in terms of the palmar aspect (P lt; 0.05), no significant difference was evident between two groups in terms of the dorsal aspect (P gt; 0.05), and the palmar aspect of each group was superior to the dorsal flap (P lt; 0.05).?Conclusion?DDPF is less invasive to donor finger, easy to be operated, able to partially restore the sensory of the injured finger, and suitable for the repair of the degloving injury of the thumb and the index finger. Combination of NVIF and FDMA can restore the fine sensory of recipient palmar flap better and is applicable for those patients suffering from digital nerve defects from the proximal phalanx and with high demand for the recovery of thumb sensory.
Object ive To explore the ef fect s of di f ferent surgical methods on plantar ulcer s in leprosy. Methods The cl inical data of 71 patients with leprosy plantar ulcers and treated with different surgical methods between October 1950 and October 2006 were analyzed retrospectively. In group A, 34 cases underwent debridement, including 26 males and 8 females aged 53-88 years old (average 72.4 years old); the course of ulcer averaged 29.0 years; the size of ulcer ranged from 5 cm × 3 cm × 2 cm to 11 cm × 7 cm × 3 cm; the disabil ity degrees of the affected foot was mild in 25 cases andsevere in 9 cases according to the self-designed evaluation system. In group B, 22 cases received foot pressure rebuilding surgery, including 19 males and 3 females aged 48-83 years old (average 69.8 years old); the course of ulcer averaged 33.5 years; the size of ulcer ranged from 5 cm × 3 cm × 2 cm to 12 cm × 7 cm × 3 cm; the disabil ity degrees of the affected foot was mild in 12 cases and severe in 10 cases. In group C, 15 cases were repaired with the transposition of toe flap, foot arch flap, acrotarsium flap, or medial tibia flap, including 11 males and 4 females aged 43-73 years old (average 64.6 years old); the course of ulcer averaged 29.3 years; the size of ulcer ranged from 6 cm × 3 cm × 2 cm to 11 cm × 5 cm × 3 cm; the disabil ity degrees of the affected foot was mild in 9 cases and severe in 6 cases. No significant differences were evident among three groups in terms of the general information (P gt; 0.05), except for the difference between group A and group C on age (P lt; 0.05). Results Group A: 19 out of 34 cases healed and the average heal ing time was 46.8 days; all patients were followed up for 2-45 years (average 17.2 years); the rate of ulcer heal ing 1 year after operation was 55.9% (19/34); 12 healed ulcer patients relapsed at average 1.5 years after operation; the rate ofulcer heal ing at last follow-up was 20.6% (7/34). Group B: 18 out of 22 cases healed and the average heal ing time was 29.2 days; all patients were followed up for 2-50 years (average 13.3 years); the rate of ulcer heal ing 1 year after operation was 81.8% (18/22); 7 healed ulcer patients relapsed at average 3.3 years after operation; the rate of ulcer heal ing at last follow-up was 50.0% (11/22). Group C: 14 out of 15 cases healed and the average heal ing time was 27.1 days; all patients were followed up for 3-12 years (average 8.8 years). The rate of ulcer heal ing 1 year after operation was 93.3% (14/15); 7 healed ulcer patients relapsed at average 4 years after operation; the rate of ulcer heal ing at final follow-up was 46.7% (7/15). For the rate of ulcer heal ing 1 year after operation, there was a significant difference between group A and group B, and between group A and group C (P lt; 0.05), but no significant difference was evident between group B and group C (P gt; 0.05). For the rate of ulcer heal ing at the final follow-up visit, there was a significant difference between group A and group B (P lt; 0.05), but no significant difference was evident between group A and group C, and between group B and group C (P gt; 0.05). Conclusion The surgical treatment of plantar ulcers in leprosy should include the alleviation of the plantar high-pressure zone and the transposition of the flaps, providing good short-term and long-term therapeutic effect.
Objective To investigate the influence of spinal cord decompression on posterior surgical treatment of thoracolumbar fracture, and to provide the practical basis for the indications of posterior spinal cord decompression Methods The cl inical data were retrospectively analyzed from 170 cases of thoracolumbar fracture treated with posterior surgical treatment between January 2005 and January 2009. There were 119 males and 51 females with an average age of42.7 years (range, 17-68 years). The fracture locations included T11 in 22 cases, T12 in 30 cases, L1 in 57 cases, and L2 in 61 cases. According to Denis classification system, there were 65 cases of compression fractures, 44 cases of burst fractures, 25 cases of flexion-distraction injuries, and 36 cases of fracture-dislocations. The time from injury to operation was 3-8 days (mean, 4.4 days). All the cases were divided into 4 groups according to space-occupying rates of spinal cord: group A, ≤20% (n=32); group B, 21%-40% (n=68); group C, 41%-60% (n=37); and group D, ≥ 61% (n=33). Through statistical analysis, the correlation between space-occupying rates and spinal cord function (Frankel grade) was evaluated, and the necessities of spinal cord decompression was studied in the patients who had neurological symptoms with space-occupying rates under 40%. Results There was no positive correlation between the degree of spinal cord injury and the space-occupying rates of bone fragments broken into the spinal canal. All patients were followed up 13-41 months (mean, 23.5 months). During the follow-up period, no secondary neurological damage occurred in the patients who were not given posterior spinal cord decompression with space-occupying rates under 40% (28 cases). And also in the cohort of patients with neurological symptoms whose space-occupying rates were under 40%, the posterior spinal cord decompression (65 cases) could improve the spinal cord function significantly when compared with no decompression cohort (7 cases), (P lt; 0.05). Conclusion The relative indications of posterior spinal cord decompression for thoracolumbar fracture are as follows: the cases having neurological symptoms with space-occupying rates under 40% and the ones having the neurological symptoms or not with space-occupying rates above 40%.
Objective To investigate the value of using Footscan system to evaluate the therapeutic effect of two internal fixation methods on calcaneus fractures. Methods From February 2006 to September 2006, 64 patients with fresh unilateral closed calcaneus fractures were randomly divided into two groups. The experimental group: 32 patients underwentminimally invasive open reduction and internal fixation with improved compressing plate and screw, including 28 males and 4 females aged 20-53 years old (average 36.7 years old); the course of disease was 3-14 days; there were 19 cases of type II, 11 of type III, and 2 of type IV according to Sanders fracture classification system. The control group: 32 patients underwent internal fixation of standard AO plate via L-shaped incision, including 29 males and 3 females aged 18-56 years old (average 37.1 years old); the course of disease was 4-15 days; there were 18 cases of type II, 11 of type III and 23 of type IV according to Sanders fracture classification system. No significant difference was noted between two groups in the general information (P gt; 0.05). At 1 and 2 years after operation, dynamic plantar pressure was measured using Footscan system, Maryland foot scores of two groups was compared, and statistical analysis was performed. Results All patients were followed up for 2 years. No infection, cuticular border necrosis, and sural nerve distal end injury occurred in the experimental group, whereas in the control group, 3 patients suffered from cuticular border necrosis and recovered after dressing, and 1 patient had sural nerve distal end injury with decreased sensation in local skin. At 1 and 2 years after operation, in the control group, there were significant differences between the injured foot and the normal foot in terms of impulse, instep index, motion range of subtalar joint, lateral displacement of footplate pressure center, and calcaneal width when patients stood on both feet (P lt; 0.05), whereas in the experimental group, no significant differences were noted between the injured foot and the normal foot in terms of the above parameters (P gt; 0.05). Significant differences were noted between two groups in terms of the above parameters (P lt; 0.05). The Maryland score 1 yearafter operation was (86.74 ± 8.56) points for the experimental group and (71.24 ± 10.06) points for the control group; at 2 years after operation, it was increased to (87.35 ± 8.49) points and (72.41 ± 9.69) points, respectively, indicating there was a significant difference between two groups (P lt; 0.05). Conclusion Operative outcomes of internal fixation with improved compressing plate are superior to those of standard AO plate. Footscan system can provide a quantitative assessment on the operative effect of calcaneus fractures.
ObjectiveTo investigate and assess the value and efficiency of percutaneous transluminal angioplasty (PTA) for the treatment of infrapopliteal arteriosclerosis obliterans in diabetic patients. MethodsFifty-one diabetic patients with infrapopliteal arteriosclerosis obliterans undergoing PTA in our department from January 2010 to January 2013 were included in this study. Among them, 43 patients were followed up for 2 years. Based on the Fontaine stage, we analyzed their ankle-brachial index (ABI) before and after surgery. The curative effects were evaluated. ResultsThe PTA success rate and clinical symptoms remission rate in Fontaine stage Ⅱ, Ⅲ, and Ⅳ group was 96.2% (25/26), 83.3% (15/18), and 42.9% (3/7), respectively. The success rate for stage Ⅱ patients was significantly higher than that for stage Ⅲ and stage Ⅳ patients (P<0.05). ABI ranged from 0.60±0.11 before surgery to 0.86±0.09, 0.85±0.08, 0.84±0.07, and 0.83±0.08, 3, 6, 12, and 24 months after surgery respectively. Paired t-test showed the difference was statistically significant (P<0.01). There were 9 cases of recurrence during the follow-up. ConclusionPTA is a safe and effective method for diabetic patients with infrapopliteal arteriosclerosis obliterans, and it can improve the patients' clinical symptoms. We can obtain a satisfactory effect in a short term, but the evaluation of long-term effect needs further follow-up.
Objective To compare the therapeutic effect of procedure for prolapse and hemorrhoids （PPH） and Block repair procedure for rectocele．Methods A retrospective study of 62 patients with surgical treatment for rectocele was analyzed．The patients were divided into PPH group （n=32） and Block group （n=30） according to the different operation procedure．The symptoms score of improvement of the patients after surgery was compared between the two groups， including operation time，intraoperative blood loss， postoperative pain score， required analgesic times， postoperative complications，hospitalization time，and hospitalization expenses．Results The symptoms of constipation of patients in two groups was significantly improved afer operation．Comparing one month with three months of Longo’s obstructed defecation syndrome （ODS） score after the operation，there was no significant difference in the PPH group（P＞0.05）， but significant difference in the Block group（P＜0.01）．Although the expenses of the PPH group was much higher than that of the Block group （P＜0.01）， the outcomes of the PPH group were much better than those of the Block group （P＜0.01）， including the postoperative Longo’s ODS score of one month and three months，operation time，intraoperative blood loss， postoperative pain score，required analgesic times，and hospitalization time．Two cases of lightly postoperative incontinence occurred in the PPH group，but completely recovered after three months in the clinical follow-up．Conclusions The PPH is as safe and effective as Block repair procedure for rectocele. The short time effect and lower recurrence rate of the PPH are better than those of the Block repair procedure．
Objective To investigate the treatment methods and the cl inical therapeutic effects of symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy. Methods A retrospective analysis was performed in 18 patients (10 males and 8 females, aged 30-62 years with an average age of 45.3 years) with cervical vertebral hemangioma associated with cervical spondylotic myelopathy between January 2006 and September 2008. The disease duration was 10-26 months (mean, 15.6 months). All patients had single vertebral hemangioma, including 2 cases at C3, 3 cases at C4, 5 cases at C5, 5 cases at C6, and 3 cases at C7. The X-ray films showed a typical “pal isade” change. According to the cl inical and imaging features, there were 13 cases of type II and 5 cases of type IV of cervical hemangioma. The standard anterior cervical decompression and fusion with internal fixation were performed and then percutaneous vertebroplasty (PVP) was used. The cervical X-ray films were taken to observe bone cement distribution and the internal fixation after operation. The recovery of neurological function and the neck pain rel ief were measured by Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) score. Results All operations were successful with no spinal cord and nerves injury, and the incisions healed well. Anterior bone cement leakage occurred in 2 cases without any symptoms. All cases were followed up 24-28 months (mean, 26 months) and the symptoms were improved at different degrees without fracture and collapse of vertebra or recurrence of hemangioma. During the follow-up, there was no implant loosening, breakage and displacement, and the mean fusion time was 4 months (range, 3-4.5 months). The JOA score and VAS score had a significant recovery at 3 months and at last follow-up when compared with preoperative values (P lt; 0.05). Based on JOA score at last follow-up, the results were excellent in 9 cases, good in 6 cases, fair in 2 cases, and poor in 1 case. Conclusion The anterior cervical decompression and fusion with internalfixation combined with PVP treatment is one of the ideal ways to treat symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy, which could completely decompress the spinal cord and effectively alleviate the cl inical symptoms caused by vertebral hemangioma.
ObjectiveTo explore the therapeutic effect of total hip arthroplasty (THA) and hip adductor amputation (HAA) in the surgical treatment of osteonecrosis of femoral head. MethodsA total of 74 patients with osteonecrosis of femoral head with hip adduction deformity were included between June 2011 and May 2012. Among them, 38 patients had undergone THA, and 36 patients had undergone THA+HAA. Statistics about hip abductor function and Harris scores before and 1 week and 12 months after the surgery were recorded. SPSS 19.0 was used for statistical analysis. ResultsThe patients' wounds had the Ⅰ-stage healing in both of the two groups. Two patients had scrotum swelling in THA+HAA group, who left the hospital after treating. One week after the surgery, the hip passive abduction angles increased (32.1±2.8) and (19.7±3.3)°, respectively in the THA+HAA group and THA group, while the Harris hip score increased 45.8±2.8 and 40.9±2.3, respectively; 12 months postoperatively, the hip passive abduction angles increased (32.2±0.9) and (26.8±2.8)°, respectively in the THA+HAA group and THA group, while the Harris hip score increased 52.7±7.2 and 49.4±4.4, respectively. The above comparative differences was statistically significant (P<0.05). ConclusionThe surgical method of adductor amputation can improve the range of motion of the hip, raise the quality of life of the patients with osteonecrosis of the femoral head after the surgery.
ObjectiveTo investigate the efficacy of macrolide antibiotics on patients with lower respiratory tract infection. MethodsA total of 146 patients with lower respiratory tract infections were selected from January 2011 to January 2014 in the Department of Respiratory Medicine of our hospital and divided into low risk and high risk group. Based on the clinical characteristics of the patients, low risk treatment plan was erythromycin capsule 0.25 g once, 3 times/day plus compound liquorice mixture, followed by clarithromycin 0.25 g once, 2-3 times/day plus compound liquorice mixture or clarithromycin 0.25 g once, 2-3 times/day plus compound liquorice mixture; high risk group treatment was macrolide antibiotics (erythromycin, clarithromycin) 0.25 g once, 3 times/day and second generation cephalosporins (cefaclor or cefuroxime) 0.25 g once, 3 times/day plus compound liquorice decoction. ResultsThe clinical seven-day curing rate was 54.1%, and the total effective rate was 93.1%. For low risk treatment regimen, the sevenday curing rate was 63.6%, and the total effective rate was 94.9%; for high risk treatment regimen, the seven-day curing rate was 34.0%, and the total effective rate was 89.4%. Acute bronchitis had high curing rate which was 70.1%. ConclusionMacrolide antibiotics (erythromycin, clarithromycin) oral administration in the treatment of lower respiratory tract infection is reliable and effective, which is worth promoting in clinical application.
Objective To observe the treatment efficacy and safety of glucosamine hydrochloride tablets on uremia patients with knee osteoarthritis (OA). Methods A total of 118 uremia patients with knee OA were selected and randomly divided into the glucosamine hydrochloride tablets treatment group (treatment group) and the coated aldehyde oxystarch capsules group (control group) with 59 cases in each group. The course was 8 weeks. The Lequesne Index was assessed for curative effect evaluation, and the change of blood indexes was observed to evaluate drug safety. Results The total effective rate of Lequesne Index in the treatment group was 72.9%, while that in the control group was 13.6%; the difference was statistically significant (χ2=42.303, P<0.001). There was no significant change in the two groups before and after treatment in terms of the patients’ dialysis adequacy, routine blood, blood electrolytes, liver and kidney function (P>0.05). Conclusion Glucosamine hydrochloride tablets is curative and safe in the treatment of uremia patients with OA.
