OBJECTIVE: To explore a better surgical mode to treat gluteal muscle contracture. METHODS: In 98 cases, superior cross incision of large tuberosity was performed in 20 cases, posterosuperior curve incision of large tuberosity was performed in 20 cases, and exteroinferior cross incision of iliac spine in the other 58 cases. The patients were observed after operation and followed up. RESULTS: The patients who received exteroinferior cross incision of iliac spine recovered soon without bleeding and infection after operation, which indicated the lowest incidental rate of postoperative complication. CONCLUSION: Exteroinferior cross incision of iliac spine is a safe and effective surgical operation to loosen the gluteal muscle contracture.
Objective To investigate the effect of neurolysis on intractable greater occipital nerve neuralgia. Methods From March 1998 to August 2005, twentysix patients suffering from intractable greater occipital nerve neuralgia were treated. There were 12 males and 14 females with an average age of 52 years(ranged 38-63 years). The disease course was 3-7 years. Sixteen cases had a long duration of work with bowing head, 5 cases symptoms appeared after trauma, and others had no identified causes. The visual analogue scales(VAS) scoring was 6.0 to 9.5, averaged 8.6. Seven cases were treated by apocope of obliquus capitis inferior under general anaesthesia and 19 cases were treated by neurolysis of greater occipital nerve under local anaesthesia. The compression mass were examined. Results Symptoms ameliorated or disappeared in 26 cases immediately after operation. The wounds healedby first intention. The pathological results of the removal mass included lymphnode (3 cases), neurilemmoma (2 cases) and scar (5 cases). The VAS scoring of 26 cases was 0 to 5 ( average, 2) 3 days after operation. Twentythree cases were followed up for 1 to 3 years. The VAS scoring of 23 cases was 0 to 4.5 ( average, 1.9) 1 months after operation. Only two cases recurred and the symptoms were ameliorated. Pain aggavated after tiredness and reliveed after oral antiinflammatory analgesics in 6 cases. No relapse occurred in the others. Conclusion The complete neurolysis of greater occipital nerve (including apocope of obliquuscapitis inferior, release between the cucullaris and semispinalis) which make the greater occipital nerve goes without any compression is the key point to treat intractable greater occipital nerve neuralgia.
OBJECTIVE: To investigate the changes of regeneration and conduction function for peripheral nerve after neurolysis by nerve special staining and electrophysiology. METHODS: Sixty Sprague-Dawley male rats were randomly divided into four groups(n = 15), four methods were designed on rats models of sciatic nerve compression. There were simple decompression as group A, internal neurolysis after decompression as group B, lemithason(0.5 mg/kg) injected in the epineurium after decompression as group C, and lemithason(0.5 mg/kg) injected around the epineurium after decompression and internal neurolysis as group D. Motor nerve conduction velocity(MNCV) and motor latency (Lan) were monitored at 1,2,3,4,5 weeks after decompression, sections were regularly taken from the previously compressed area to perform morphometric analysis. RESULTS: After 2 weeks of decompression, the significant recovery were observed in both MNCV and Lan of four groups. Up to the 5th week of decompression, recovery of electrophysiology was significantly faster in group C and D than that of group A and B, particular in group C(P lt; 0.05), while group A compared with group B, there was no statistical difference in both MNCV and Lan(P gt; 0.05). Morphometric analysis showed that a lot of neural regeneration fibers were observed in group C and D after 3 weeks of decompression. CONCLUSION: Decompression can improve nerve conduction function significantly, while injection of lemithason in epineurium after decompression can promote the structure and function recovery of injured nerve.
Objective To evaluate the safety and efficacy of the operation performed under the video-assisted thoracoscope to release the anterior part of the spine of the patient with severe adolescent idiopathic scoliosis (AIS). Methods From April 2004 to July 2006, 24 patients with AIS (Illness course, 1.5-9 years; Lenke Ⅰ in 17 patients, Lenke Ⅱ in 7; right scoliosis in 22, left scoliosis in 2), among whom there were 9 males and 15 females, with an average age of 14.7 years (range, 11-21 years) at the time of the operation. Before operation, the thoracic vertebral Cobb anger at the coronal plane was averaged 78.3°(range, 65-125°). All the patients had normal muscle strength and muscle tension in their lower limbs, but 5 of the patients had a decrease of the superficial sensation in their lower limbs. All the patients had a moderately or severely decreased lung reserve function. Under general anesthesia, the patient was placed in the lateral position to set up a work channel for thoracoscopy. The releasing of the thoracic intervertebral space and the confluence of the bone grafts were performed. During Stage Ⅰ or Stage Ⅱ, the orthopedic procedures for the posterior part of the scoliosis spine, the internal fixation, and the confluence ofthe bone grafts were completed. ResultsAll the patients survived the periodof perioperation. During operation, there was a hemorrhage of 50-200 ml, averaged 100 ml, with a postoperative thoracic closely-drained fluid of 100-150 ml. The incision was healed by the first intention. Each patient underwent the releaseof 4-6 intervertebral spaces, with an average of 5.5 spaces released. The average coronal Cobb angle was 45.6°(range, 25-75°). The physiological curvatureat the sagittal plane was normal, with an improved shape of the spine. The follow-up for 3-18 months averaged 9.3 months revealed that the bilateral pulmonary markings were clear, with confluence of the orthopedic segment of the spine. The patients could live and work normally, and had a significantly-improved psychological condition and an active social participation because of their improved appearance. Conclusion The releasing of the anterior part of the spine under the video-assisted thoracoscope can effectively release the adolescent idiopathic scoliosis and improve the flexibility of the spine, with a smaller degree of the surgical wound and a faster and clearer exposure of the spinal column during operation.
Talipes equinovarus is a very common con-genital foot deformity. From 1985 till 1989,tatalof 30 feet in 23 Patients had been operated by theauthor using subtalar realigment procedure afterall the necessayr release with neurovascular bundleprotected. The position was kept by 2 Kirschner swires,one through talonavicular joint into the talus and other through calcaneous vertically upward into the talus without penetrating into the anklejoint. The total period of plaster immobilizationranged from 8 to 12 weeks. The average age at surgery 6 months old.The results were excellent in 24 feet, good in 5 and less satisfactory in 1 due to overcorrection.
ObjectiveTo investigate the expression changes of the receptor activator of nuclear factor-κB ligand (RANKL) in the peripheral blood of patients with aseptic loosening of the implant after total hip arthroplasty (THA) by comparing with that of patients with femoral neck fracture and to analyze the correlation between RANKL expression and aseptic loosening. MethodsBetween January 2008 and January 2013,the peripheral blood were harvested from 58 patients with aseptic loosening of the implant after THA (trial group) and 63 patients with femoral neck fracture (control group).The 2 groups were well matched,with no significant differences in age and gender (P>0.05).The expressions of the RANKL mRNA and RANKL protein were evaluated by quantitative real-time PCR and Western blot respectively.At the same time,the concentration of RANKL was also measured by ELISA. ResultsThe expression of the RANKL mRNA in the trial group was 18.30±1.09,which was significantly higher than that of control group (1.00±0.05)(t=125.390,P=0.000).The relative RANKL protein expression values in trial group and control group were 0.856±0.254 and 0.404±0.102 respectively,showing significant difference (t=13.032,P=0.000).The results of ELISA showed that the concentration of RANKL in trial group [(3.553 5±0.129 7) ng/mL] was significantly higher than that of control group [(1.912 3±0.126 2) ng/mL] (t=18.124,P=0.000). ConclusionThe high RANKL expression in peripheral blood is probably correlated with aseptic loosening of the implant in patients undergoing THA,which possibly is the prognostic factor of aseptic loosening of the implant.
【Abstract】 Objective To explore the reasons of tendon adhesions post tendon allograft. Methods From May1990 to June 2000, 85 cases receiving tendon allograft were given tenolysis because of tendon adhesions. There were 76 males and 9 females, with an average age of 24.5 years (8-46 years). Injury was caused by machine in 38 cases, electric in 32 cases, cut in 4 cases, explosion in 4 cases and extremity mutilation in 7 cases; including 66 cases of flexor tendon deficit and 19 cases of extensor tendon deficit. Six cases had 1 tendon deficit, 79 cases had tendon deficit of more than 2. The defect region ranged from I to V. The total mobil ity of the joint was less than 220° in 73 cases. The impairment of skin, bone, nerve and vascular were treated before tendon allograft. Results Because TAM was less than 50% of TPM, the patients were given tenolysis 4-15 months after operation. And the mobil ization began at the first day after operation to improve the range of active movement. Patients were followed up 7-17 years (mean 12.7 years). TAM and TPM were in accord. Mean total mobil ity of joint was200°. Conclusion The serious of primary hurt is the important factors of tendon adhesion. Improvement of tendon selected, treatment and early mobil ization can rel ieve the tendon adhesion.

Objective? To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Methods Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the cl inical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main cl inical manifestations included lameness and abnormal gait. The medical examination showed pelvic obl ique and relative inequal ity of lower l imbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic obl ique. The CT scans showed no abnormal finding except pelvic obl ique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabil itation exercise. Results All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic obl ique, and 2 patients had obvious pelvic obl ique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Conclusion Unilateral gluteal muscle contracture leads to pelvic obl ique and inequal ity of lower l imbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and rehabil itation exercises.
