Objective To investigate the pathogenesis, diagnosis, and treatment of the gluteal muscle contracture associated with an unequal leg length caused by the pelvis obliquity (GMC-PO).Methods The retrospective analysis was made on the clinical features and the follow-up results in 132 patients who had been admitted from January 1990 to December 2004 for GMC-PO. Among them, 73 weremale and 59 were female with a range in age from 5 to 26 years (average, 11 yr). All the patients were characterized by unsymmetrical contracture of the gluteal muscles, including unilateral and bilateral contracture. Of the patients, 89 had a clear limping and 78 had a clearly-unequal leg length. The X-ray examination revealed pelvis obliquity in 97 cases and an increased angle of the femur neck in 11 cases. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of thegluteal muscles was performed, combined with the skin traction of both legs andexercise training. Results Of the 132 patients withunequal gluteal muscle contracture before operation, 13 had a relative length difference of 0.5-1.5 cm between the 2 legs, 1 had a difference of 3.0 cm,and the remaining 118 patients had an equal leg length. Excellent and good resultswere achieved in 118 and 13 patients, respectively after 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 functional exercises. Only 1 patient had a poor result. The follow-up for 3 months to 14 years showed that thecure rate was as high as 99.2%.Conclusion The gluteal musclecontracture associated with an unequal leg length caused by the pelvis obliquity is a result of the unequal gluteal muscle contracture between the 2 hips and it can be cured with a comprehensive therapeutic method including the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateralarea nearby the greater trochanter, and postoperative skin traction as well as the functional exercise.

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 summarize the current research progress on the concept, clinical presentation, diagnosis, biomechanical changes, and pathological mechanisms of the medial meniscus posterior root tear (MMPRT), and its clinical correlations with tibial rotation. MethodsThe research literature on MMPRT and its relationship with tibial rotation at home and abroad in recent years was extensively consulted and summarized. Results MMPRT is a specific and common type of medial meniscus injury of the knee joint. The occurrence of posterior medial pumping pain events following low-energy trauma in patients provides important clues for the diagnosis of this injury, with MRI being the preferred imaging modality. The biomechanical effects generated by MMPRT are similar to those caused by total removal of the medial meniscus. And this injury is usually associated with tibial rotation. MMPRT induces pathological external rotation of the tibia, which can be restored by timely medial meniscus posterior root repair. Furthermore, changes in tibial rotation are related to the healing status after medial meniscus posterior root repair. ConclusionMMPRT is closely related to tibial rotation. Understanding the biomechanics, pathological mechanisms, and clinical correlations between the two is of great significance for improving the diagnosis and treatment strategies.
Objective To determine the influence of combinative assessment of 64 multi-slice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) on the selection of operative procedures of upper rectal cancer in multi-disciplinary team. Methods Prospectively enrolled 110 patients, who were diagnosed definitely as upper rectal cancer (distance of tumor to the dentate line gt;7 cm) at West China Hospital of Sichuan University from August 2007 to October 2008, randomly assigned into two groups. In one group named MSCT+SAA group, both MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT group, only MSCT was made preoperatively. Then, the pooled data were analyzed for the correlative relationship between the choice of surgery strategy and clinicopathologic factors. Furthermore, the preoperative staging and predicted operative procedures were compared with postoperative pathologic staging and practical operative procedures, respectively. Results According to the criteria, 106 patients with upper rectal cancer were randomly assigned into MSCT+SAA group (n=52) and MSCT group (n=54). The baseline characteristics of two groups were statistically identical. When analyzing the proportion of multiple clinicopathologic factors in different operative procedures of upper rectal cancer, there were statistical differences in the preoperative N staging (P=0.003), M staging (P=0.022), TNM staging (P=0.003), serum level of SAA (P=0.005) and general category of tumor (P=0.027). For MSCT+SAA group the accuracies of preoperative staging T, N, M and TNM were 84.6%, 86.5%, 100% and 86.5%, respectively; For MSCT group the corresponding rates were 83.3%, 2.9%, 100% and 64.8%, respectively. There were statistically significant differences accuracies of preoperative N staging and TNM staging (P=0.005, P=0.009, respectively) in two groups. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups (96.2% vs. 81.5%, P=0.017). Conclusion Combinative assessment of 64 MSCT and SAA could improve the accuracy of preoperative staging, and thus provide higher predictive coincidence rate to operative procedures for surgeon.
Objective To investigate the surgery tactics for ossification of ligamentum flavum (OLF) associated with dural ossification (DO) in the thoracic spine and the cl inical outcome. Methods Between June 2006 and December 2009, 98 patients with thoracic spinal stenosis secondary to OLF were treated, and DO was found in 18 cases during operation. There were 11 males and 7 females with a mean age of 58 years (range, 46-73 years). The disease duration ranged from 5 to 48 months (mean,20 months). All patients underwent surgical decompression because of recent neurological aggravation. Both DO and OLF were resected with octagonal decompression by dissecting pedicle flavum tunnel. The Japanese Orthopaedic Association (JOA) score, modified Oswestry Disabil ity Index (ODI), and the Cobb angle were used to evaluate the effectiveness. Results The initial symptoms were significantly alleviated postoperatively. All patients had transient cerebrospinal fluid (CSF) leakage postoperatively, the CSF leakage disappeared after 8-10 days of conservative treatment. All the incisions healed by first intention. There was no complication of neurologic function deterioration, meningitis, wound infection, or spinocutaneous fistula. Eighteen patients were followed up 20-60 months (mean, 49 months). No recurrence of spinal cord compression symptoms,or neurologic function deterioration was observed at last follow-up. The JOA scores and effectiveness and modified ODI scores were significantly improved after 1 month and 12 months of operation when compared with preoperative scores (P lt; 0.05). The Cobb angles of kyphosis of the involved vertebrae were (6.7 ± 1.6)° before operation and (8.0 ± 1.2)° after 12 months of operation, showing significant difference (t=4.000，P=0.001). Postoperative T2-weighted axial MRI, sagittal MRI scan, and short T1 inversion recovery MRI showed that compressed deformity of the spinal cord returned to normal. Conclusion The surgery tactics for thoracic spinal stenosis secondary to the OLF with DO is safe, and no patching dura mater tears is effective.

ObjectiveTo observe the characteristic of optical coherence tomography (OCT) and subfoveal choroidal thickness(SFCT) in patients with multiple evanescent white dot syndrome (MEWDS). MethodsThe clinical data of 10 patients (10 eyes)with MEWDS were included in the study. 10 normal subjects with matched age, gender and ocular refractive status was selected as control. The patients including 9 females (9 eyes) and 1 male (1 eye), with the average age of (27±8) years. The onset time ranged from 5 to 14 days. The patients were in acute phase if it was in 2 weeks after onset, or convalescent phase if onset was 8 weeks ago. The corrected vision, slit lamp biomicroscopy, ophthalmoscope, fundus photography, fundus fluorescein angiography, indocyanine green angiography and optical coherence tomography (OCT) were performed alone or combined in all patients. The SFCT between the acute and convalescent phases were measured using enhanced depth imaging OCT. The average follow-up was 5 months. The OCT characteristics of affected eyes between acute and convalescent phase were compared. The SFCT of the affected eyes and fellow eye were compared. ResultsThe foveal inner segment-outer segment (IS/OS) was disrupted, thin, irregular in the acute phase, and restored in the convalescent phase. The SFCT of patients in the acute phase was (239±140.7) μm, in the convalescent phase was (189.9±115.6) μm. The SFCT in the acute phase was more thicker than the convalescent phase (t=5.287, P < 0.05). The SFCT of fellow eyes in the acute phase was (214.6±127.2) μm, in the convalescent phase was (186.5±108.6) μm, the difference was significant(t=3.553, P < 0.05).The SFCT in the control subject was (155.5±83.5) μm. The SFCT in the acute phase was thicker than the control(Z=-2.117, P < 0.05). ConclusionsIn the acute phase of MEWDS, the foveal IS/OS was disrupted, thin and irregular in OCT scan. The choroid is thicker in the acute phase than in the convalescent phase in both eyes, and thicker than controls.
