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.
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 discuss the surgical procedures and curative effect of stiff 2-5 metacarpophalangeal (MP) joints after crash injury in hand. Methods Between January 2006 and June 2009, 7 cases of stiff 2-5 MP joints were treated by releasing the stiff MP joints and reconstructing the function of lumbrical muscle in one stage. There were 6 males and 1 female with an average age of 32 years (range, 18-56 years). All injuries were caused by crash. Six cases suffered from multiple metacarpal fracture or complex dislocation of MP joint and 1 case suffered from complete amputation at level of middle palm of hand. The interval from initial wound heal ing to hospital ization was 3 to 15 months. Before operation, the X-ray films showed fracture healed and the results of nipping paper test were positive. All hands were treated with physical therapy for 1 month. After the plaster external fixation for 6 weeks, the physical therapy and function training were given. Results All wounds healed by first intention. The patients had no joint instabil ity and extensor tendon side-sl ipping with normal finger function. Six patients were followed up from 6 months to 3 years. The extension and flexion of MP joint were 0° and 67-90°, respectively. The average grip strength of injured dominant hand reached 86.70% of normal side and non-dominant hand reached 66.70% of normal side. The average injured dominant tip pinch strength reached 83.52% of normal side and non-dominant tip pinch strength reached 61.30% of normal side. Based on total active motion (TAM) system of Chinese Medical Association for Hand Surgery, the results were excellent in 4 cases, good in 1 case, and fair in 1 case; the excellent and good rate was 83.33%. Conclusion In patients with stiff MP joint and lumbrical muscle defect, releasing stiff MP joint and reconstructing lumbrical function in one stage can recover the function of MP joint and achieve good outcome. Physical therapy plays an important role before operation.
Objective To evaluate and compare the efficacy of anterior subcutaneous and submuscular transposition of the ulnar nerve in treating cubital tunnel syndrome. Methods From August 2006 to August 2008, 66 patients with cubital tunnel syndrome were treated with anterior subcutaneous transposition (subcutaneous group, 24 cases) and with anterior submuscular transposition (submuscular group, 42 cases). According to McGowan stages, all patients were at Stage2 or 3 entrapment neuropathy with paresthesia in the ring and small fingers. Respectively, 3 cases and 8 cases compl icated by interosseous muscle atrophy in subcutaneous group and in submuscular group. No significant difference was found in gender, age, duration of the disease, and compl ication between two groups (P lt; 0.05). The surgical features, distribution of Bishop rates, two-point discrimination test, muscular strength, and compl ications were recorded. Results The operation time was (28.4 ± 5.2) minutes in subcutaneous group and (43.8 ± 5.6) minutes in submuscular group, showing significant difference (P lt; 0.01). The incision length was (12.2 ± 2.5) cm in subcutaneous group and (13.6 ± 2.8) cm in submuscular group, showing significant difference (P lt; 0.05). All patients were followed up 1-3 years. According to Bishop scoring system, the results were excellent in 18 cases, good in 4 cases, and poor in 2 cases in subcutaneous group; excellent in 36 cases, good in 3 cases, and poor in 3 cases in submuscular group; and showing no significant difference between two groups (P gt; 0.05). At 6 months postoperatively, twopoint discrimination and grip strength were improved when compared with that of preoperation (P lt; 0.05), but there was no significant difference between two groups (P gt; 0.05). Pain and dysesthesia of the scar were noted in 1 patient of the subcutaneous group and 3 patients of the submuscular group. No infection or hematoma was found and no patient needed reoperation. Conclusion Both operative methods are effective alternative for treating cubital tunnel syndrome. The anterior ubcutaneous anterior transposition of the ulnar nerve has fewer traumas, and it is a better choice for some old patients.
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.
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.
ObjectiveTo compare the mid-term effectiveness of arthroscopic shoulder capsular release combined with acromiohumeral distance (AHD) restoration in the treatment of diabetic secondary stiff shoulder and primary frozen shoulder. Methods A retrospective analysis was conducted on clinical data of 22 patients with diabetic secondary stiff shoulder (group A) and 33 patients with primary frozen shoulder (group B), who underwent arthroscopic 270° capsular release combined with AHD restoration treatment. There was no significant difference between the two groups in gender, age, affected side, disease duration, and preoperative AHD, shoulder flexion range of motion, abduction range of motion, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS) score, and Constant score (P>0.05). Only the difference in the internal rotation cone rank and external rotation range of motion between the two groups showed significant differences (P<0.05). The improvement in shoulder pain and function was evaluated by using VAS score, ASES score, and Constant score before operation and at last follow-up. Active flexion, abduction, external rotation range of motion, and internal rotation cone rank were recorded and compared. AHD was measured on X-ray films.Results All patients were followed up 24-92 months (median, 57 months). There was no significant difference in follow-up time between group A and group B (P>0.05). No fractures or glenoid labrum tears occurred during operation, all incisions healed by first intention, and no complication such as wound infection or nerve injury was observed during the follow-up. At last follow-up, there were significant improvements in active flexion, abduction, external rotation range of motion, internal rotation cone rank, AHD, VAS score, ASES score, and Constant score when compared with preoperative ones in both groups (P<0.05). Except for the difference in change in external rotation range of motion, which had significant difference between the two groups (P<0.05), there was no significant difference in other indicators between the two groups (P>0.05). ConclusionArthroscopic capsular release combined with AHD restoration can achieve good mid-term effectiveness in the treatment of diabetic secondary stiff shoulder and primary frozen shoulder. However, the improvement in external rotation range of motion is more significant in the patients with diabetic secondary stiff shoulder.
