We confirmed the prcathesis should beimplanted in the space between the nasal boneand the complex. The reason for complicationhappened in this approach was that...
Objective To summarize the current research progress about influence of patellofemoral osteoarthritis on clinical outcome of unicompartmental knee arthroplasty (UKA). Methods The recent related literature was extensively reviewed and summarized, including pros and cons to regard the patellofemoral osteoarthritis as the contraindication. Results Previous studies regarded patellofemoral osteoarthritis as the contraindication of UKA. Most of current researches show that the damage to the articular cartilage of the patellofemoral joint to the extent of full-thickness cartilage loss has no influence on outcome of UKA. There is no correlation between preoperative anterior knee pain or medial patellofemoral joint degeneration and the clinical outcome. However, lateral subluxation of the patella has an adverse impact on postoperative curative effect. Degeneration of the lateral patellofemoral joint may be a risk factor of the outcome. Conclusion Patellofemoral osteoarthritis should not be the absolute contraindication of UKA. The effect of degeneration of the lateral patellofemoral joint is not clear at present, and still needs further studies in the future.
Objective To investigate the method and effectiveness of coracoplasty with mini-incision for subcoracoid impingement syndrome. Methods Between May 2006 and September 2011, 4 patients with subcoracoid impingement syndrome were treated, including 3 cases of congenital dysplasia of the coracoid process and 1 case of anterior glenohumeral instability. There were 3 males and 1 female with an average age of 36 years (range, 20-56 years). The disease duration was 6-22 months (mean, 11.2 months). The patients had a history of chronic pain and click of the anterior should, which was aggravated in adduction, internal rotation, and flexion. The results of the coracoid impingement test were positive by Neer and Hawkins-Kennedy impingement sign. The axial CT in adduction position showed that the coracohumeral interval decreased and coracoid index increased. The 2 cm lateral coracoid incision was made and the 0.5-1.5 cm coracoid neck was revealed and cut by osteotomy. The coracoplasty was performed by amputating the conjoined tendon insertion of the short head of the biceps and the coracobrachialis muscle and suturing to proximal coracoid osteotomy surface. Shoulder was fixed with the external braces for 6 weeks. Results Healing of incision by first intention was observed in all cases without any complication. All the 4 patients were followed up from 8 months to 5 years. At last follow-up, pain and click disappeared. The mean visual analogue scale (VAS), University of California at Los Angeles (UCLA), Constant, and simple shoulder test (SST) scores were significantly improved from 7.75, 10.25, 65.50, and 9.75 at preoperation to 0.25, 34.25, 91.25, and 0.25 at last follow-up respectively. The axial CT in adduction position and MRI showed that long coracoid process was removed; the coracohumeral interval was increased to 13.38 mm from 4.16 mm at preoperation; and the coracoid index was decreased to 0.28 mm from 13.08 mm at preoperation. Conclusion Coracoplasty with mini-incision is an effective method to relieve clinical symptoms of subcoracoid impingement, which has less complications and faster recovery.
Objective To investigate the effectiveness and adverse effect of the absorbable fixation system on cranial bone flap reposition and fixation after craniotomy. Methods Between July 2010 and December 2011, 67 cases underwent cranial bone flap reposition and fixation with absorbable fixation system after craniotomy and resection of intracranial lesions. There were 38 males and 29 females with a median age of 32 years (range, 5 months to 73 years). The disease duration ranged from 3 months to 6 years (median, 25 months). Forty-one lesions were located at supratentorial and 26 at subtentorial, including at the frontotemporal site in 13 cases, at the frontoparietal site in 12 cases, at the temporal oprietal site in 8 cases, at the temporooccipital site in 5 cases, at the occipitoparietal site in 4 cases, and at the posterior cranial fossa in 25 cases. The diagnosis results were glioma in 15 cases, cerebral vascular diseases (aneurysm, arteriovenous malformation, and cavemous angioma) in 8 cases, meningioma in 7 cases, arachnoid cyst in 7 cases, acoustic neurinoma in 5 cases, cholesteatoma in 3 cases, primary trigeminal neuralgia in 5 cases, cerebral abscess in 3 cases, hypophysoma in 2 cases, craniopharyngioma in 2 cases, metastatic tumor in 2 cases, radiation encephalopathy in 2 cases, medulloblastoma in 1 case, ependymocytoma in 1 case, germinoma in 1 case, atypical teratoma/rhabdoid tumor in 1 case, facial spasm in 1 case, and subdural hematoma in 1 case. Intracranial lesion size ranged from 3 cm × 2 cm to 7 cm × 5 cm. The changes of local incision and general condition were observed. Results Subcutaneous effusion occurred in 2 supratentorial lesions and 3 subtentorial lesions, which was cured at 2 weeks after puncture and aspiration. All incisions healed primarily and no redness or swelling occurred. CT scans showed good reposition of the cranial bone flap and smooth inner and outer surfaces of the skull at 2 weeks after operation. All 67 patients were followed up 3-20 months (mean, 10.3 months). During follow-up, the skull had satisfactory appearance without discomfort, local depression, or effusion. Moreover, regular CT and MRI scans showed no subside, or displacement of the cranial bone flap or artifacts. Conclusion Absorbable fixation system for reposition and fixation of the cranial bone flap not only is simple, safe, and reliable, but also can eliminate the postoperative CT or MRI artifact caused by metals fixation system.
Objective To investigate the clinical therapeutic effects on malignant spinal tumors treated by percutaneous vertebroplasty(PVP) under the guidance of the digital subtraction angiography(DSA). Methods A retrospective analysis was performed in 196 patients (99 males and 97 females, aged 23-85 years, averaged 60.4 years) with malignant spinal tumors, who underwent the PVP treatment combined with standard chemotherapy and other comprehensive treatment from January 2002 to January 2005. The malignant spinal tumors had their origins as follows: lung cancer (66 cases), breast cancer (55 cases), liver cancer (19 cases), colon cancer (15 cases), stomach cancer (9 cases), prostate cancer (12 cases), multiple myeloma (16 cases), and malignant lymphoma of the spine (4 cases).The metastatic tumors involved the cervical vertebra (32 cases), thoracic vertebra (93 cases), lumbar vertebra (71 cases), and spinal column, including 1 vertebral segment (135 cases), 2 segments (50 cases), and more than 3 segments (11 cases). During the follow-up survey, changes in the visual analogue pain scale(VAS) and changes in the X-ray measurements of the average anterior height, midline height, and posterior height of the diseased vertebra were observed. Results The follow-up for 6 months to 3 years revealed that the percutaneous vertebroplasty on279 vertebral segments had a success with an operational success rate of 100%. Bone cement was injected into the lesions 1-9 ml per segment of the spine. The postoperative X-ray and CT evaluations revealed that spinal stabilization was obtained in all the patients. After operation, 193（98.5%）patients had an obvious decrease or disappearance of the pain in the lower back, and only 3 (1.5%) patients had no obvious improvement in the pain. There was a significant statist-ical difference in the VAS scores between before operation and after operation (Plt;0.05). There were also significant statistical differences in the average anterior height of the diseased vertebra between before operation and after operation（15.71±2.80 mm vs 16.61±3.01 mm）, in the midline height（13.65±2.93 mm vs 14.52±2.72 mm）, and in the posterior height（23.67±2.81 mm vs 23.70±3.13 mm,Plt;0.05). The patients with lung or liver cancer had a mean survival time of 9 monthsafter PVP; the patients with breast cancer, stomach cancer, prostate cancer, lymphoma, or other metastatic tumors had a mean survival time of 18 months. The patients with multiple myeloma had a mean survival time of 27 months. The differences were statistically different (Plt;0.01). Conclusion PVP under the guidance of the DSA is an easier operation witha small wound and few complications. It can effectively alleviate the patient’s pain due to metastatic spinal tumor, stabilize the spine, improve the patient’s quality of life, and reduce the incidence of paraplegia.
Abstract： Objective To evaluate the effect of a surgical method for treating mild- to moderate-ischemic mitral regurgitation（IMR） using a self-designed device during off-pump coronary artery bypass grafting（OPCAB）. Methods From September 2009 to August 2011, six patients（4 males, 2 females； age was 52-73 years） with mild- to moderate-IMR underwent OPCAB and concomitant mitral valvuloplasty using a self-designed device in Beijing An Zhen Hospital. Their degree of IMR, anteroposterior diameter of mitral annulus, left ventricular long-axis diameter, left ventricular short-axis diameter and left ventricular spherical index（left ventricular short-axis diameter/left ventricular long -axis diameter）were measured using transesophageal Doppler echocardiography before and after mitral valvuloplasty. Their mean aorta pressure, mean pulmonary artery pressure and central venous pressure were also measured via Swan-Ganz catheter before and after mitral valvuloplasty. Perioperative cardiac function indexes were compared. Results There was no in-hospital death. IMR of all patients disappeared postoperatively. After mitral valvuloplasty their anteroposterior diameter of mitral annulus（3.43±0.08 cm vs.3.68±0.08 cm；t=5.430, P=0.001）, left ventricular short-axis diameter（4.80±0.21 cm vs.5.53±0.11 cm；t=7.530, P=0.001）and left ventricular spherical index（0.64±0.02 vs.0.74±0.01；t=11.110, P=0.002）significantly decreased than those before mitral valvuloplasty . But their left ventricular long-axis diameter and hemodynamic indexes did not change significantly after mitral valvuloplasty. All the six patients were followed up at the out-patient department 3 months postoperatively without autonomous symptoms. Their heart function improved to I class（New York Heart Association）. Echocardiography showed 4 patients without IMR and 2 patients with trace of minimalIMR. Conclusion Off-pump surgical therapy for mild- to moderate- IMR during OPCAB can help the patients reverseremodeling of the left ventricle, avoid the risks of cardiopulmonary bypass and improve cardiac function with good short-term effects. This method may be a good choice for treating patients with IMR.
Objective To conduct a systematic review of the construction methods, predictive factors, and model quality of risk prediction models for postoperative chronic pain in knee replacement surgery patients, providing evidence for the development of nursing-sensitive dynamic prediction models. Methods A systematic review of risk prediction models for postoperative chronic pain in knee replacement surgery patients was conducted by searching PubMed, Web of Science, Cochrane Library, CINAHL, SinoMed, CNKI, Wanfang Database, and VIP Database. The search period was from the establishment of the databases to February 28, 2025. Two researchers independently screened the literature, extracted data, and assessed the risk of bias and applicability of the included studies. Results A total of 10 studies involving 10 predictive models were included in this review. Among these, three models underwent internal validation, and one model underwent external validation. Commonly reported predictive factors included postoperative 24-hour Numerical Rating Scale scores, postoperative knee function scores, sleep disorders, preoperative depression, postoperative functional exercises, postoperative complications, preoperative pain, and postoperative C-reactive protein levels. All 10 studies had a high risk of bias and were generally applicable. Conclusions Existing risk prediction models generally rely on static indicators and lack dynamic monitoring of postoperative rehabilitation behaviors and psychosocial factors, with severe deficiencies in model validation. Future research should focus on developing nursing-led multidimensional dynamic models that incorporate functional exercise adherence data collected via wearable devices, standardize external model validation, and enhance clinical translation value.
Objective To evaluate the effectiveness of the shared decision-making scheme in postoperative out-of-hospital extended care for patients with total hip/knee arthroplasty (THA/TKA). Methods Patients who underwent THA/TKA in the Department of Orthopedic Surgery at West China Hospital of Sichuan University between October 2023 and April 2024 were included using convenience sampling. Patients were divided into the control group (odd-numbered dates) and the intervention group (even-numbered dates) based on the surgical dates. The intervention group was received care guided by a shared decision-making protocol, whereas the control group was followed the standard post-arthroplasty follow-up procedures. Differences between the two groups were compared in terms of decision-making capacity, decision satisfaction, and hip/knee function at the following time points: on the day of discharge, 3 weeks after discharge, 2 months after discharge, and 3 months after discharge. Results A total of 118 patients were included, with 59 cases in each group. There were no significant differences in demographic and clinical characteristics between the two groups (P>0.05). In terms of decision-making, compared with the control group, the experimental group had stronger decision-making ability, lower decision-making conflict, and more satisfaction with the decision-making process (P<0.05). In terms of joint function, the experimental group showed better joint function than the control group at 3 weeks, 2 months, and 3 months after surgery (P<0.05). There was no significant difference in the pain dimension of the Western Ontario and McMaster Universities Osteoarthritis index between the two groups (P=0.199). Conclusions Compared with the traditional follow-up protocol, the shared decision-making protocol can enhance patient engagement in medical decision-making, reduce decisional conflict, improve satisfaction with the decision-making process, and simultaneously promote joint functional recovery and expedite the rehabilitation process.
ObjectiveTo explore the surgical outcome of Duckett urethroplasty-urethrotomy for staged hypospadias repair. MethodsFifty-three patients with hypospadias were treated by 2 stages between August 2013 and September 2014. The age ranged from 10 months to 24 years and 3 months (median, 1 year and 10 months). There were 5 cases of proximal penile type, 2 cases of penoscrotal type, 36 cases of scrotal type, and 10 cases of perineal type. Urethroplasty was performed with tubed transverse preputial island flap only in 27 cases or combined with urethral plate in the other 26 cases, thus a urethrocutaneous fistula was intentionally created; stage II fistula repair was carried out at 1 year after stage I repair. ResultsThe length of the new urethra ranged from 2 to 8 cm with an average of 3.6 cm. The patients were followed up 5-17 months with an average of 8 months after stage II repair. After stage I repair, urethral fistula was noted at other site in 3 cases, skin necrosis in 1 case, glandular stricture in 2 cases, cicatric curvature in 1 case, and position and morphology of urethral orifice not ideal in 4 cases. After stage II repair, urethral fistula was noted in 2 cases, mild urethral diverticulum in 2 cases, and stricture at temporary repair site in 1 case. HOSE score was 12-16 at 3 months after stage II repair (mean, 14.5). At 3-14 months after stage II repair, the maximum flow rate ranged from 3.9 to 22.7 mL/s with an average of 8.6 mL/s. ConclusionDuckett urethroplasty-urethrotomy can be used as staged repair for primary treatment of hypospadias because of high safety, low complication incidence, and satisfactory appearance.
