Objective To investigate the clinical application of skin soft-tissue expansion in repairing large-cicatricial alopecia. Methods From January 1989 to December 2003, 38 cases of large cicatricial alopecia were repaired by expanding scalp. The scalp was expanded, the cicatrix area was resected and the mode of propulsive or rotary flap was adopted. The size of alopecia ranged from 15 cm×7 cm to 23 cm×15 cm. Results The cicatricial alopecia in all the 38 cases was repaired and the hair growth was excellent during 1.2 year follow-up. Conclusion The soft tissue expansion technique is the initiative choice and an efficient method for repairing large cicatricial alopecia.
Objective To compare the short-term effectiveness and the impact on cervical segmental range of motion using Prodisc-C Vivo artificial disc replacement and Zero-P fusion for the treatment of single-segment cervical spondylosis. MethodsThe clinical data of 56 patients with single-segment cervical spondylosis who met the selection criteria between January 2015 and December 2018 were retrospectively analyzed, and they were divided into study group (27 cases, using Prodisc-C Vivo artificial disc replacement) and control group (29 cases, using Zero-P fusion) according to different surgical methods. There was no significant difference between the two groups in terms of gender, age, type of cervical spondylosis, disease duration, involved segments and preoperative pain visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), surgical segments range of motion, upper and lower adjacent segments range of motion, overall cervical spine range of motion, and cervical curvature (P>0.05). The operation time, intraoperative blood loss, postoperative hospitalization stay, time of returning to work, clinical effectiveness indicators (VAS score, JOA score, NDI, and improvement rate of each score), and imaging indicators (surgical segments range of motion, upper and lower adjacent segments range of motion, overall cervical spine range of motion, and cervical curvature, prosthesis position, bone absorption, heterotopic ossification, etc.) were recorded and compared between the two groups. ResultsThere was no significant difference in operation time and intraoperative blood loss between the two groups (P>0.05); the postoperative hospitalization stay and time of returning to work in the study group were significantly shorter than those in the control group (P<0.05). Both groups were followed up 12-64 months, with an average of 26 months. There was no complication such as limb or organ damage, implant failure, and severe degeneration of adjacent segments requiring reoperation. The VAS score, JOA score, and NDI of the two groups at each time point after operation significantly improved when compared with those before operation (P<0.05); there was no significant difference in the above scores at each time point after operation between the two groups (P>0.05); there was no significant difference in the improvement rate of each score between the two groups at last follow-up (P>0.05). The surgical segments range of motion in the study group maintained to varying degrees after operation, while it in the control group basically disappeared after operation, showing significant differences between the two groups (P<0.05). At last follow-up, there was no significant difference in the upper and lower adjacent segments range of motion in the study group when compared with preoperative ones (P>0.05), while the upper adjacent segments range of motion in the control group increased significantly (P<0.05). The overall cervical spine range of motion and cervical curvature of the two groups decreased at 3 months after operation, and increased to varying degrees at last follow-up, but there was no significant difference between groups and within groups (P>0.05). At last follow-up, X-ray films and CT examinations showed that no prosthesis loosening, subsidence, or displacement was found in all patients; there were 2 cases (7.4%) of periprosthetic bone resorption and 3 cases (11.1%) of heterotopic ossification which did not affect the surgical segments range of motion. ConclusionBoth the Prodisc-C Vivo artificial disc replacement and Zero-P fusion have satisfactory short-term effectiveness in treatment of single-segment cervical spondylosis. Prodisc-C Vivo artificial disc replacement can also maintain the cervical spine range of motion to a certain extent, while reducing the occurrence of excessive motion of adjacent segments after fusion.
【摘要】 目的 探讨椎管内囊肿的手术治疗疗效。 方法 2006年5月-2009年12月对30例患者的临床表现、影像学和治疗情况进行回顾性分析。 结果 30例均行手术治疗，3例为椎管内单侧硬膜下髓外囊肿，3例为脑脊膜囊肿，12例为髓外硬脊膜下囊肿，9例为神经根袖套部囊肿（Tarlov囊肿），3例为脊管内肠源性囊肿。术后21例症状消失；9例好转，其中3例术后发生脑脊液漏，伤口二次缝合未成功，后经内引流后切口愈合。 结论 椎管内囊肿的临床表现及体征复杂，不典型，与椎管内肿瘤及椎间盘突出症的临床表现和体征相似；对症状及体征明显者宜施行手术治疗，手术治疗效果较满意。【Abstract】 Objective To evaluate the therapeutic effect of the surgery on intraspinal cyst. Methods A total of 30 patients from May 2006 to December 2009 were collected, and the clinical manifestations, results of examinations and therapeutic effects were retrospectively analyzed. Results All the patients underwent the surgery, inluding 3 with unilateral intraspinal subdural extramedullary cyst, 3 with meningeal cyst, 12 with subdural extramedullary cyst, 3 with nerve-root oversleeve cyst (Tarlov cyst), and 3 with intra-spinal-canal enterogenous cyst. Afterh the surgery, the symptoms disappeared in 21 patients, alleviated in 9 including 3 with postoperative cerebrospinal-fluid leakage whose wound was not sutured successfully for the second time and healed up after drainage. Conclusions The clinical manifestations of intraspinal cyst are complicated and untypical, which is similar to that of intraspinal tumor and slipped disc. The surgeries should be performed on the patients with obvious symptoms and the therapeutic effect is good.
Objective To evaluate the clinical effects of surgical treatment for 30 patients with discogenic low back pain. Methods A total of 30 patients with 36 intervertebral discs were treated with posterior approach lumbar discectomy and interbody fusion with internal fixation by strict criteria. All patients were followed up for one year. The low back pain before and one year after surgery was evaluated by Japanese Orthopaedic Association (JOA) score and Visual Analogue Scale (VAS) score. Results The patients’ JOA score increased from 14.6±2.3 (before operation) to 27.1±0.9 (one year after operation) (t=–26.936, P<0.001), while the patients’ VAS score decreased from 6.2±1.6 (before operation) to 1.4±0.9 (one year after operation) (t=16.335, P<0.001), and the differences were significant. Conclusion When the conservative treatment is invalid, the operation of posterior lumbar intervertebral fusion is an effective method for the patinets with discogenic low back pain.
