RESUMO

Anterior cruciate ligament reconstruction (ACLR) using hamstring tendon (HT) graft aims to stabilise the knee, but it may bring some complications like anterior knee (AKP) pain that can have consequences on the functional aspect of this surgery. The aim of this study was to compare isokinetic knee strength and functional outcomes between patients with and without AKP following an ACLR using HT graft during the first-year post-surgery. Three hundred and thirty subjects operated by ACLR using hamstring tendon graft were included in our retrospective cohort and divided into two groups: a group with AKP (AKP+ group) and one without AKP (AKP-group). In our population, 14.8% of the patients had AKP. At 4 post-operative months, subjects with pain had lower isokinetic strength limb symmetry index (LSI) for knee flexors and extensors, and a lower Lysholm score than subjects without pain (p < 0.0001). These differences did not persist at 7 post-operative months, and there was no difference in the one-leg hop test. After multivariate analysis, we highlighted the impact of time on the evolution of these parameters. Yet, the exact definition of AKP after ACLR remains to be clearly defined since an imprecise diagnosis may lead to inappropriate management. Pre-operative information about this type of complication, which evolves favourably with time, could be useful for patients. Indeed, AKP can occur after ACLR, even if a HT graft has been used, compared to other surgical procedures using the knee extensor apparatus as patellar tendon graft (AKP is associated with the donor site morbidity). In case of AKP after ACLR, monitoring the muscle inhibition by isokinetic tests may enable clinicians to adapt the retraining and the return to sport.

RESUMO

BACKGROUND: Chronic neuropathic pain can be severely disabling and is difficult to treat. The medial thalamus is believed to be involved in the processing of the affective-motivational dimension of pain, and lesioning of the medial thalamus has been used as a potential treatment for neuropathic pain. Within the medial thalamus, the central lateral nucleus has been considered as a target for stereotactic lesioning. OBJECTIVE: To study the safety and efficacy of central lateral thalamotomy using Gamma Knife radiosurgery (GKRS) for the treatment of neuropathic pain. METHODS: We retrospectively reviewed all patients with neuropathic pain who underwent central lateral thalamotomy using GKRS. We report on patient outcomes, including changes in pain scores using the Numeric Pain Rating Scale and Barrow Neurological Institute pain intensity score, and adverse events. RESULTS: Twenty-one patients underwent central lateral thalamotomy using GKRS between 2014 and 2021. Meaningful pain reduction occurred in 12 patients (57%) after a median period of 3 months and persisted in 7 patients (33%) at the last follow-up (the median follow-up was 28 months). Rates of pain reduction at 1, 2, 3, and 5 years were 48%, 48%, 19%, and 19%, respectively. Meaningful pain reduction occurred more frequently in patients with trigeminal deafferentation pain compared with all other patients (P = .009). No patient had treatment-related adverse events. CONCLUSION: Central lateral thalamotomy using GKRS is remarkably safe. Pain reduction after this procedure occurs in a subset of patients and is more frequent in those with trigeminal deafferentation pain; however, pain recurs frequently over time.

RESUMO

A woman in her late 70s with bilateral total hip arthroplasty (THA) presented with left hip pain arising immediately after the last THA procedure, progressively worsening. Clinically, a severe abductor insufficiency with Trendelenburg limp was observed. Moreover, symptomatic leg length discrepancy required a contralateral heel lift of 0.5 cm. She was previously managed conservatively without any clinical benefit. Radiographs showed a well-fixed uncemented straight, sitting proud stem. MRI showed a large abductor tear. A minimally invasive proximal advancement of the greater trochanter was planned to allow direct surgical repair of the abductor lesion. The patient made a good recovery, and 12 months after surgery, wire removal was performed. The patient gained significant improvements in hip function (Harris Hip Score from 52 to 89), full limp recovery and complete pain relief at 13 months follow-up from primary surgery.

RESUMO

OBJECTIVE: To evaluate the clinical efficacy of spinal endoscopy in the treatment of severe free lumbar disc herniation and explore the feasibility and application of microscopic drills to expand ventral space. METHODS: Thirty patients with severe free lumbar intervertebral disc herniation treated by spinal endoscopic technique from April 2019 to March 2021 were collected, including 19 males and 11 females;aged from 19 to 76 years with an average of (44.03±16.92) years old. All patients had a single segmental lesion with prolapse of the nucleus pulposus. Among them, there were 3 cases on L2,3, 3 cases on L3,4, 15 cases on L4,5, and 9 cases on L5S1. During operation, posterior bone of vertebral body and pedicle notch were removed by a drill under the endoscope to enlarge the ventral space. And the free nucleus pulposus was exposed and completely removed. The intraoperative blood loss, operation time, hospital stay and postoperative neurological complications were recorded, and Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI) and visual analogue scale (VAS) were compared before operation, 2 days, 3 months and 1 year after operation, and Macnab standard was used to evaluate clinical efficacy. RESULTS: All operations were successful and the free nucleus pulposus was completely removed. Pain in the lower back and legs was significantly relieved on the day after operation. Two patients experienced transient pain and numbness in lower limbs after operation, and no serious nerve injury complications occurred. ODI and VAS at each time point after surgery were significantly lower than those before surgery (P<0.01), and JOA score was significantly higher than before surgery (P<0.01). The excellent and good rates of Macnab were 66.67% (20/30), 83.33% (25/30) and 90.00% (27/30) on 2 days, 3 months and 1 year after operation, respectively. CONCLUSION: For severe free lumbar intervertebral disc herniation, using of a drill under endoscope to expand the ventral space can smoothly remove the free nucleus pulposus and avoid nerve damage.

RESUMO

BACKGROUND: To compare the clinical outcomes of patients with lumbar disc herniation treated with robot-assisted percutaneous endoscopic lumbar discectomy (r-PELD) or conventional PELD under fluoroscopy guidance (f-PELD). METHODS: Our study group included 55 patients, 22 in the r-PELD group and 33 in the f-PELD group. The following clinical and surgical outcomes were compared between the two groups: the visual analog scale for radiculopathy pain; Oswestry Disability Index; intraoperative volume of blood loss; frequency of fluoroscopy used during the procedure; and MacNab classification. The follow-up period was 6-8 months. RESULTS: Compared with f-PELD, r-PELD was associated with a lower volume of intraoperative blood loss and frequency of fluoroscopy (p < 0.01). There were no differences in complications, MacNab classification, postoperative disability and leg pain, and duration of hospitalization between the two groups. CONCLUSION: Based on our findings, r-PELD provides a safe and effective alternative to conventional PELD for the treatment of lumbar disc herniations, with the accuracy for placement of punctures lowering radiation exposure.

RESUMO

Flatfoot could be divided into flexible flatfoot and rigid flatfoot. Flatfoot with symptoms is called symptomatic flatfoot, surgical treatment is required if conservative treatment is not effective. Subtalar arthroereisis is a minimally invasive procedure which has been used for many years with good results in flexible flatfoot, however, still has many controversial points. Controversial points focus on indications and contraindications, optimal age, subtalar arthroereisis alone or not, efficacy and safety of absorbable material implants, and implant removal. The paper reviewed and summarized the use and controversies of subtalar arthroereisis in symptomatic flatfoot as follows:the best indication for subtalar arthroereisis was pediatric flexible flatfoot syndrome and aged from 10 to 12 years old was optimal age for treatment;tarsal coalitions with flatfoot and adult flatfoot were relative indications. Stiff flatfoot, joint laxity, and subtalar arthritis were contraindications;obesity and neurogenic flexible flatfoot were relative contraindications. The correction ability of subtalar arthroereisis alone was limited, and it's combined with other procedures depending on patient's situation. The safety and efficacy of absorbable material implants had been reported. Routine removal of the implant was not necessary, the main reason of which was tarsal sinus pain.

RESUMO

PURPOSE: This ongoing trial is comparing the efficacy and safety of three ablation treatments for cervical intraepithelial neoplasia grade 2 or higher. Here, we present early data regarding pain, side effects, and acceptability of CO2 gas-based cryotherapy (CO2), nongas cryotherapy, and thermal ablation (TA). Efficacy results are expected to become available in late 2023. MATERIALS AND METHODS: This noninferiority randomized trial is taking place in El Salvador, China, and Colombia. Patients are 1,152 eligible women with biopsy-confirmed cervical intraepithelial neoplasia grade 2 or higher who will receive one of three ablation treatments. Pain is measured before, during, and after treatment with a visual analog scale (1-10). Side effects and acceptability are assessed at 6 weeks. RESULTS: To date, 1,024 of 1,152 (89%) women were randomly assigned to treatment. The median pain level was higher during TA (4, IQR = 4) than CO2 (2, IQR = 4) or nongas cryotherapy (2, IQR = 4) (P < .01, range: 0-10). The most common post-treatment symptom was watery discharge, reported by 97.9% of women, and it lasted longer in the CO2 group than the other two treatments (in days, median [IQR]: CO2 = 20[20], nongas cryotherapy = 15[10], TA = 18[15], P < .01). Bleeding was reported more frequently in women treated with TA (27.6%) than CO2 (17.5) or nongas cryotherapy (18.7%) (P < .01). The majority of patients reported being very satisfied with the treatment they received at 6 weeks (91%) and again at 12 months post-treatment (97%). CONCLUSION: Despite differences in pain and side effects across ablation treatments, all were safe and highly acceptable to patients. In addition to efficacy, considerations such as cost and portability may be more significant in choosing a treatment method.

RESUMO

BACKGROUND: Uniportal interlaminar contralateral endoscopic lumbar foraminotomy (ICELF) aims to achieve decompression of lumbar spinal stenosis in the contralateral lateral recess and foraminal and extraforaminal regions of the same segment. This technique is performed under normal saline irrigation using an endoscope with optical lens magnification close to the targeted stenotic segment and has the potential of lower incidence of exiting nerve root dorsal root ganglion irritation. METHODS: A systematic review of the ICELF technique was conducted from March 2000 to March 2022. Articles were selected with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Eligibility of studies was independently determined by 2 reviewers, and disagreements were resolved by a third author. RESULTS: Eight retrospective cohort studies comprising 194 patients with foraminal stenosis who underwent uniportal ICELF were selected for systematic review. Mean age range was 62-79 years, and surgical duration was 48-73.5 minutes. There was significant improvement in Oswestry Disability Index and visual analog scale leg pain score in the included studies. Four studies met the minimum clinically significant difference for leg pain, with visual analog scale improved >5 points and Oswestry Disability Index improved >8.2 points. Four studies reported a majority of the operated patients with good or excellent outcomes following surgery, with a low rate of complications in the studies selected. CONCLUSIONS: There is low-level evidence that ICELF when performed by an experienced spinal endoscopic surgeon is effective in providing pain relief and improved function with low rate of complications in select patients.

RESUMO

PURPOSE: Fixed bearing (FB) UKA constituted 63.7% of unicondylar knee arthroplasties in 2020 Australian Registry with the longest UKA survivorship. The significance of patellofemoral joint (PFJ) arthritis, ACL deficiency, post-operative anteromedial pain, radiosclerosis or radiolucency on survivorship of FB UKA is not established. The aim of this study was to analyze the medium-term survivorship of fixed-bearing UKA with no exclusion of PFJ OA and ACL deficiency. Predictors for failure were analyzed. METHODS: FB UKA performed in 2011-17 were reviewed. Cases with PFJ OA or ACL deficiency were not excluded. The effect on survivorship by ACL deficiency, PFJ arthritis, post-operative anteromedial pain and radiological abnormalities were analyzed. RESULTS: There were 96 UKA with follow-up time of 66 ± 18 months (27-98). The mean age was 70 ± 9 years, BMI 25.8 ± 2.6 kg/m2. Alignment was varus 9° ± 4° pre-operatively and varus 3° ± 3° post-operatively. There were four revisions (4.2%) and 4 deaths (4.2%). Reasons for revisions were loosening (n = 1), persistent pain (n = 2) and lateral compartment disease (n = 1). Estimated survival at 8.3 years was 94.7% (95% CI 91.6-97.7). BMI ≥30 was found to be a significant predictor for failure. The incidence of radiographic abnormalities was 75% for PFJ arthritis, 39% for tibial tray overhang, 14% for radiolucency or radiosclerosis, 5% for ACL deficiency and 5% for edge loading respectively but they were not significantly associated with lower survivorship or anteromedial knee pain. The presence of anteromedial pain after surgery in 36.5% was also not significantly associated with survivorship. CONCLUSION: FB UKA with no exclusion of early PFJ arthritis and ACL deficiency has satisfactory medium-term survivorship. BMI ≥30 could have higher risk of all-cause revision. Tibial tray overhang, non-progressive radiolucency or radiosclerosis do not seem to be associated with anteromedial knee pain or poorer medium term survivorship.

RESUMO

Objective: To investigate the mid- and long-term effectiveness of external fixator distraction arthroplasty in the treatment of moderate to severe ankle arthritis. Methods: The clinical data of 23 patients with moderate to severe ankle arthritis treated with external fixation distraction arthroplasty who met the selection criteria between January 2007 and November 2019 were retrospectively analyzed. There were 20 males and 3 females; the age ranged from 21 to 65 years, with an average age of 43.7 years. Etiology included 8 cases of primary ankle arthritis, in which 5 cases combined with varus deformity; 15 cases of traumatic ankle arthritis, the cause of injury was 5 cases after ankle fracture surgery, 3 cases after Pilon fracture surgery, 5 cases of chronic ankle instability and repeated sprain, and 2 cases of other causes. According to Takakura staging system, there were 4 cases of stage ⅢA, 12 cases of stage ⅢB, and 7 cases of stage Ⅳ; according to Giannini staging system, there were 5 cases of stage Ⅱ and 18 cases of stage Ⅲ; according to Cheng staging system, 16 cases were in stage Ⅲ, and 7 cases stage Ⅳ. American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) score were used to evaluate the improvement of ankle pain and function before operation and at last follow-up, and the data were analyzed according to different etiological groups. At last follow-up, the surgical results were evaluated subjectively and objectively. The changes of ankle joint space before operation and at last follow-up were compared. The patients were divided into two groups according to their age: ≤45 years old group [young group, 10 cases, aged (35.62±7.41) years old] and >45 years old group [middle-aged and elderly group, 13 cases, aged (54.20±6.20) years old]. The AOFAS ankle-hindfoot score and VAS score were compared before and after operation between the two groups, and the influence of age on distraction arthroplasty was analyzed. Results: The external fixator was removed after 3 months of continuous distraction,12 patients got infection around the wire tunnels. All the 23 patients were followed up 13-143 months, with an average of 56.9 months; the follow-up time was (43.46±32.77) months and (69.80±37.79) months in the young group and middle-aged and elderly group, respectively. At last follow-up, the AOFAS ankle-hindfoot score and VAS score significantly improved when compared with those before operation ( P<0.05). According to etiological analysis, there was no significant difference in AOFAS ankle-hindfoot score and VAS score before and after operation ( P>0.05) in Pilon fracture patients, while the significant difference was found in remaining patients ( P<0.05). There was significant difference in AOFAS ankle-hindfoot score before operation between the young group and the middle-aged and elderly group ( t=2.110, P=0.040), but no significant difference in preoperative VAS score and the differences in VAS score and AOFAS ankle-hindfoot score before and after operation between the two groups ( P>0.05). The subjective and objective results of pain evaluation at last follow-up showed that 4 patients had no pain, 12 patients had moderate pain relief, 5 patients had mild pain relief, and 2 patients had no significant pain relief; among the 10 patients who were followed up more than 5 years, there were 2, 5, 2, and 1 patient, respectively; 2 patients who were followed up more than 10 years had moderate pain relief. At last follow-up, the ankle joint space was (3.7±0.4) mm, which significantly increased when compared with before operation [(1.5±0.2) mm] ( t=1.791, P=0.002). The ankle joint space was (2.9±0.5) mm in 10 patients who were followed up more than 5 years, and 3.3 mm and 3.0 mm in 2 patients who were followed up more than 10 years. Conclusion: Distraction arthroplasty of the ankle joint can achieve satisfactory results in patients with moderate to severe ankle arthritis (except for arthritis caused by Pilon fracture), and age has no significant effect on distraction arthroplasty.

RESUMO

BACKGROUND: Local anesthesia is feasible for both transforaminal and interlaminar approaches in percutaneous endoscopic lumbar discectomy (PELD). However, the optimal approach for PELD has not yet been established at the L5/S1 segment under local anesthesia with 1% lidocaine. OBJECTIVES: In this study, we compared the transforaminal approach with the interlaminar approach of PELD under local anesthesia for L5/S1 disc herniation (DH). STUDY DESIGN: This was a prospective randomized clinical trial. METHODS: From January 2019 to March 2020, 91 consecutive patients with L5/S1 DH who planned to undergo PELD in our unit were randomized to the transforaminal endoscopic lumbar discectomy (TELD, n = 46) or interlaminar endoscopic lumbar discectomy (IELD, n = 45). Both procedures were performed under local anesthesia with 1% lidocaine. The clinical outcomes were assessed as the Visual Analog Scale (VAS) score, Oswestry Disability Index (ODI) score, and modified MacNab criteria. Patient satisfaction surveys and surgical complications were also recorded and analyzed. RESULTS: Compared to the IELD group, the TELD group had a shorter operative time and postoperative bed rest time (P < 0.001) but a longer radiation time (P < 0.001) and lower VAS scores for intraoperative back pain (P < 0.001) and leg pain (P < 0.001). At the postoperative follow-up, there were no significant differences between the 2 groups in the VAS scores, ODI scores, or modified MacNab criteria. The surveys showed a significantly higher satisfaction rate in the TELD group than in the IELD group (P = 0.014). Six patients in the IELD group (13.3%) needed extra intravenous injections of sufentanil because of intense pain during the procedure. In the IELD group, there were 2 cases of neuropathic pain after surgery. LIMITATIONS: Due to the study was included in a single spine center with a relatively small population and its relatively short-term follow-up, the study is not generalizable. CONCLUSIONS: Both TELD and IELD can provide good clinical outcomes for L5/S1 DH under local anesthesia with 1% lidocaine. TELD was superior to IELD in terms of surgical-related experience and complications.

RESUMO

OBJECTIVE: Gamma Knife radiosurgery is recognized as an efficient intervention for the treatment of refractory trigeminal neuralgia (TN). The CyberKnife, a more recent frameless and nonisocentric radiosurgery alternative, has not been studied as extensively for this condition. This study aims to evaluate the clinical outcomes of a first CyberKnife radiosurgery (CKRS) treatment in patients with medically refractory TN. METHODS: A retrospective cohort study of 166 patients (168 procedures) with refractory TN treated from 2009 to 2021 at the Centre Hospitalier de l'Université de Montréal was conducted. The treatment was performed using a CyberKnife (model G4, VSI, or M6). The treatment median maximum dose was 80 (range 70.0-88.9) Gy. RESULTS: Adequate pain relief, evaluated using Barrow Neurological Institute pain scale scores (I-IIIb), was achieved in 146 cases (86.9%). The median latency period before adequate pain relief was 35 (range 0-202) days. The median duration of pain relief for cases with a recurrence of pain was 8.3 (range 0.6-85.0) months. The actuarial rates of maintaining adequate pain relief at 12, 36, and 60 months from the treatment date were 77.0%, 62.5%, and 50.2%, respectively. There was new onset or aggravation of facial numbness in 44 cases (26.2%). This facial numbness was predictive of better maintenance of pain relief (p < 0.001). The maintenance of adequate pain relief was sustained longer in idiopathic cases compared with cases associated with multiple sclerosis (MS; p < 0.001). CONCLUSIONS: In the authors' experience, CKRS for refractory TN is efficient and safe. The onset or aggravation of facial hypoesthesia after treatment was predictive of a more sustained pain relief, and idiopathic cases had more sustained pain relief in comparison with MS-related cases.

RESUMO

OBJECTIVE: Trigeminal neuralgia (TN) secondary to tumor represents a rare and diverse entity, and treatment for secondary TN remains controversial. This report reviews a single institution's experience in treating secondary TN with stereotactic radiosurgery (SRS) and focuses on the durability of pain relief with respect to various treatment targets, i.e., the trigeminal nerve, offending tumor, or both. METHODS: Between the years 2009 and 2021, 21 patients with TN secondary to benign (n = 13) or malignant (n = 8) tumors underwent SRS. Barrow Neurological Institute (BNI) pain intensity scale scores were collected from patient electronic medical records at baseline, initial follow-up, and 1 and 3 years post-SRS. The interval change in BNI scale score (ΔBNI) at the various follow-up time points was also calculated to assess the durability of pain relief following SRS. RESULTS: The median follow-up period was 24 (range 0.5-155) months. Five patients (24%) received treatment to the trigeminal nerve only, 10 (48%) received treatment to the tumor only, and 6 (29%) had treatment to both the nerve and tumor. The overall radiation dosage ranged from 14 to 60 Gy delivered in 1-5 fractions, with a median overall dose of 26 Gy. The median dose to the tumor was 22.5 (range 14-35) Gy, delivered in 1-5 fractions. Of the treatments targeting the tumor, 25% were delivered in a single fraction with doses ranging from 14 to 20 Gy, 60% were delivered in 3 fractions with doses ranging from 18 to 27 Gy, and 15% were delivered in 5 fractions with doses ranging from 25 to 35 Gy. The most common dose regimen for tumor treatment was 24 Gy in 3 fractions. The median biologically effective dose (with an assumed alpha/beta ratio of 10 [BED10]) for tumor treatments was 43.1 (range 13.3-60.0) Gy. There was a significant difference in the proportion of patients with recurrent pain (ΔBNI score ≥ 0) at the time of last follow-up across the differing SRS treatment targets: trigeminal nerve only, tumor only, or both (p = 0.04). At the time of last follow-up, the median ΔBNI score after SRS to the nerve only was -1, 0 after SRS to tumor only, and -2 after SRS to both targets. CONCLUSIONS: SRS offers clinical symptomatic benefit to patients with TN secondary to tumor. For optimal pain relief and response durability, treatment targeting both the tumor and the trigeminal nerve appears to be most advantageous.

RESUMO

OBJECTIVES: The main objective was to investigate 5-year outcomes in patients with knee osteoarthritis, randomised to one of two non-surgical treatments. SETTING: Two outpatient clinics. PARTICIPANTS: At baseline, 100 patients with radiographic and symptomatic knee osteoarthritis not found eligible for knee replacement (KR) were included. Main exclusion criteria were average score above 75 of the Knee injury and Osteoarthritis Outcome Score (KOOS) subscales pain, symptoms, function of daily living and quality of life; KOOS4 and average knee pain the previous week greater than 60 mm on a 100 mm visual analogue scale. INTERVENTIONS: Patients were randomised to supervised non-surgical treatment consisting of patient education, supervised exercise, weight loss, insoles, and pain medication (the MEDIC treatment) or written advice. The 12-week MEDIC treatment included patient education, neuromuscular exercise, insoles and a dietary weight loss programme and/or pain medication if needed and written advice consisted of two leaflets. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was 5-year mean change for KOOS4. Secondary outcomes included KOOS subscales, self-reported health, usage of pain medication and self-reported physical activity. RESULTS: Thirty-nine (78%) and 36 (72%) from the MEDIC and written advice groups responded at 5 years. There were no between-group differences in KOOS4 (difference 5.3 (95% CI -1.5 to 12.1) or any secondary outcomes. However, the 95% CI included the minimal clinically important difference for the main outcome.Seventy-six percent of the MEDIC group and 66% of the written advice group experienced clinically important improvements in KOOS4.Fifteen patients (30%) from the MEDIC group and 17 (34%) from the written advice group received KR in the index knee. Undergoing KR did not result in a statistically significant greater improvement in KOOS4 (difference 6.1 (95% CI -1.1 to 13.4). CONCLUSIONS: No statistically significant differences between supervised non-surgical treatment and written advice were demonstrated at 5 years. Most patients experienced clinically important improvements, irrespective of initial treatment strategy or KR. TRIAL REGISTRATION NUMBER: NCT01535001; ClinicalTrials.gov.

RESUMO

Background: Uterine fibroids are most common in women aged 30-50 and are the most common benign gynecological tumors. Relevant data suggest that about 25% of patients with uterine fibroids are at childbearing age. Uterine fibroids not only cause the discomfort symptoms, and affect the pregnancy, but also have certain malignant transformation risk, thus needed to be treated positively and promptly. Aim: This study is aimed at exploring the effect of laparoscopic myomectomy and comprehensive rehabilitation nursing on patients with uterine fibroids. Methods: The clinical data of 110 cases of uterine fibroids admitted to our hospital from August 2019 to December 2021 were analyzed retrospectively, and they were divided into two groups according to postoperative rehabilitation strategies. Both groups were treated with laparoscopic myomectomy. The A group was treated with routine rehabilitation strategy, while the B group was treated with comprehensive rehabilitation nursing strategy. The differences in operation-related indicators, stress factors, inflammatory factors, nutritional indicators, knowledge mastery, occurrence of adverse symptoms and pain scores, negative emotion scores, nursing satisfaction, and simplified comfort status scale (GCQ) scores between the two groups under nursing strategies were compared. Results: The postoperative exhaust time (13.14 ± 2.03) h, bed time (9.86 ± 1.94) h, postoperative hospital stay (4.37 ± 1.31) d, and total hospital stay (6.78 ± 1.69) d in the B group were shorter than those in the A group, and the hospitalization expenses (0.74 ± 0.25) million were less than those in the A group (P < 0.05). Before operation, stress factors, inflammatory factors, and nutritional indexes were compared between the two groups (P > 0.05). On the 3rd day after operation, tumor necrosis factor-α (TNF-α), cortisol (Cor), norepinephrine (NE), and interleukin-1ß (IL-1ß) in the two groups showed a significantly upward trend compared with those before operation, and albumin and transferrin were significantly fell compared with those before operation. However, the values of stress factor and inflammatory factor in the B group were significantly lower than those in the A group, and the values after the decrease of nutritional index were significantly higher than those in the A group (P < 0.05). The pain scores at 24 h, 48 h, and 72 h after operation in the B group were significantly lower than those in the A group (P < 0.05). Negative emotions, nursing satisfaction, and GCQ scores were compared between the two groups before intervention (P > 0.05). After the intervention, the scores of Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) in the two groups were significantly lower than those before the intervention, and the scores of nursing satisfaction and GCQ were higher than those before the intervention. The values of negative emotions in the B group after the decline were significantly lower than those in the A group, while the values of nursing satisfaction and GCQ after the increase were higher than those in the A group (P < 0.05). The excellent and good rate of knowledge acquisition in the B group was 94.55% (52/55), which was significantly higher than 78.18% (43/55) in the A group (P < 0.05). The incidence of adverse symptoms in the B group was 9.09% (5/55), which was lower than 21.82% (12/55) in the A group, while the difference was not statistically significant (P > 0.05). Conclusion: Laparoscopic myomectomy combined with comprehensive rehabilitation nursing can reduce the postoperative stress state of patients with uterine fibroids, improve patient satisfaction, reduce adverse emotions, and promote rehabilitation.

RESUMO

Objective: To investigate the effectiveness of unilateral biportal endoscopic discectomy (UBED), percutaneous endoscopic lumbar discectomy (PELD), and traditional fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). Methods: The clinical data of 347 LDH patients who met the selection criteria and underwent discectomy between January 2017 and December 2021 were retrospectively analyzed. They were divided into FD group (160 cases), PELD group (86 cases), and UBED group (101 cases) according to operation methods. There was no significant difference in gender, age, surgical level distribution, disease duration, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between groups ( P>0.05). The operation time, hospitalization stay, treatment cost, and incidence of surgery-related complications were recorded and compared between groups. The patients' pain and functional recovery were evaluated by VAS score and ODI before and after operation. Results: The operation time of FD group was significantly shorter than that of PELD group and UBED group, and the hospitalization stay was significantly longer than that of PELD group and UBED group ( P<0.05); there was no significant difference between PELD group and UBED group ( P>0.05). The treatment cost in UBED group was significantly higher than that in PELD group, and in PELD group than in FD group ( P<0.05). All the patients were followed up 6-24 months, with an average of 14.6 months. VAS score of lower extremity and ODI in 3 groups significantly improved after operation when compared with that before operation ( P<0.05). At 1 day after operation, VAS score of lower extremity of UBED group was significantly better than that in PELD group and FD group ( P<0.05), but there was no significant difference between PELD group and FD group ( P>0.05). There was no significant difference in VAS scores of lower extremity between the 3 groups at 1 and 3 months after operation ( P>0.05). The difference of ODI before and after operation in FD group and UBED group was slightly better than that in PELD group ( P<0.05), and there was no significant difference between FD group and UBED group ( P>0.05). Incidence of surgery-related complications in FD group (20.0%) was significantly higher than that in PELD group (12.8%) and UBED group (6.9%), and PELD group was significantly higher than UBED group ( P<0.05). All the incision infection occurred in FD group (12 cases), symptomatic disc cyst and myeloid hypertension-like occurred in 1 case each in PELD group. Conclusion: UBED, PELD, and FD have similar effectiveness on lower extremity pain in early LDH. Compared with FD, UBED and PELD have the advantage of shorter hospitalization stay and fewer complications.

RESUMO

BACKGROUND: Patellar resurfacing is optional during total knee replacement (TKR). Some surgeons always resurface the patella, some never resurface, and others selectively resurface. Which resurfacing strategy provides optimal outcomes is unclear. We assessed the effectiveness of patellar resurfacing, no resurfacing, and selective resurfacing in primary TKR. METHODS: A systematic review and meta-analysis was performed. MEDLINE, Embase, Web of Science, The Cochrane Library, and bibliographies were searched to November 2021 for randomised-control trials (RCTs) comparing outcomes for two or more resurfacing strategies (resurfacing, no resurfacing, or selective resurfacing) in primary TKR. Observational studies were included if limited or no RCTs existed for resurfacing comparisons. Outcomes assessed were patient reported outcome measures (PROMs), complications, and further surgery. Study-specific relative risks [RR] were aggregated using random-effects models. Quality of the evidence was assessed using GRADE. RESULTS: We identified 33 RCTs involving 5,540 TKRs (2,727 = resurfacing, 2,772 = no resurfacing, 41 = selective resurfacing). One trial reported on selective resurfacing. Patellar resurfacing reduced anterior knee pain compared with no resurfacing (RR = 0.65 (95% CI = 0.44-0.96)); there were no significant differences in PROMs. Resurfacing reduced the risk of revision surgery (RR = 0.63, CI = 0.42-0.94) and other complications (RR = 0.54, CI = 0.39-0.74) compared with no resurfacing. Quality of evidence ranged from high to very low. Limited observational evidence (5 studies, TKRs = 215,419) suggested selective resurfacing increased the revision risk (RR = 1.14, CI = 1.05-1.22) compared with resurfacing. Compared with no resurfacing, selective resurfacing had a higher risk of pain (RR = 1.25, CI = 1.04-1.50) and lower risk of revision (RR = 0.92, CI = 0.85-0.99). CONCLUSIONS: Level 1 evidence supports TKR with patellar resurfacing over no resurfacing. Resurfacing has a reduced risk of anterior knee pain, revision surgery, and complications, despite PROMs being comparable. High-quality RCTs involving selective resurfacing, the most common strategy in the UK and other countries, are needed given the limited observational data suggests selective resurfacing may not be effective over other strategies.

RESUMO

BACKGROUND: The purpose of this study is to evaluate the change patterns of leg numbness (LN) after lumbar decompression surgery (LDS), and to find the predictive factors that affect the recovery of numbness. METHODS: Patients who underwent LDS in our institution between August 2020 and July 2021 were prospectively enrolled in this study, and were followed by a 12-month follow-up. The degree of LN, leg pain (LP) and the disability were assessed using the visual analog scale (VAS) and oswestry disability index (ODI). RESULTS: A total of 314 patients finished the 12-month follow-up. The preoperative mean VAS-LN score was 3.49 ± 2.44, which decreased to 1.91 ± 1.30 at 3 months, to 1.29 ± 0.97 at 6 months and to 1.26 ± 0.96 at 12 months after surgery. The preoperative mean VAS-LP score was 6.05 ± 1.30, which decreased to 2.00 ± 0.86 at 3 months, to 1.02 ± 0.80 at 6 months, and to 0.49 ± 0.71 at 12 months after surgery. The preoperative mean ODI score was 27.90 ± 7.08, which decreased to 9.73 ± 3.09 at 3 months, to 6.72 ± 2.98 at 6 months, and to 4.57 ± 2.76 at 12 months after surgery. Via multivariate logistic regression analysis, only preoperative VAS-LN score (p < 0.001*) was identified as a significantly independent predictive factor for residual LN after operation. CONCLUSION: Clinically significant improvement in LN was observed in the majority of patients within 6 months after LDS, and the improvement of VAS-LN was slower than the VAS-LP. High pre-operative VAS-LN score can independently predict the presence of residual LN after surgery at 12-month follow up.

RESUMO

Adjacent segment stenosis can occur after lumbar fusion surgery, leading to significant discomfort and pain. If further surgeries are required, the choice of the operative technique is an individual decision. In patients without over instability, it is still uncertain whether patients with adjacent spinal stenosis should be treated like primary lumbar spinal stenosis via decompressive surgery alone or with decompression and fusion. This is a retrospective analysis with prospective collected data. We included patients with adjacent segment stenosis after lumbar fusion. Patients with spinal deformity and/or obvious instability and/or significant neuroforaminal stenosis were excluded. All patients were divided into two groups according to the surgical technique that has been used: (a) treated via microsurgical decompression (MDG), (b) decompression and fusion of the adjacent segment (FG). Treatment decision was at discretion of the surgeon. Primary outcome was the need for further lumbar surgery after 1 year. In addition, patient reported outcome was measured via numerical rating scale (NRS), SF-36, Oswestry disability Index (ODI), Pittsburgh Sleep Quality Index (PSQI), and General Depression Scale before and after 1 year after surgery. In a further follow-up, need for additional lumbar surgery was redetermined. Total study population was 37 patients with a median age of 72 years. A total of 86.1% of patients suffered from a proximal adjacent segment stenosis and most common level was L3/4 (51.4%). A total of 61.1% of included patients developed adjacent segment stenosis after fusion of one single lumbar segment. Eighteen patients were included in MDG and 19 patients in FG. Both groups benefited from surgical interventions and there was no significant difference concerning pain, pain associated disability, sleeping, life quality, and mood after 1 year or the need of follow-up surgeries 1 year after primary fusion (5 in MDG vs. 5 in FG, p = 0.92) and at the second follow-up with a median time after surgery of 30 months (6 in MDG vs. 7 in FG, p = 0.823). Duration of surgery and hospital stay was significant shorter in MDG. There was no difference concerning operative complications rate. Both groups improved significantly in pain associated disability index, pain in motion, and concerning the sleeping quality. The present study indicates that decompression may not be inferior to decompression and fusion in patients suffering from degenerative adjacent segment stenosis without obvious signs of instability, deformation, and neuroforaminal stenosis after lumbar fusion in short-term follow-up. Due to significant shorter time of surgery, a pure microsurgical decompression may be a sufficient alternative to a decompression and fusion, particular regarding old age of this patient cohort.

RESUMO

The treatment of proximal interphalangeal joints (PIP) after a traumatic injury has produced disappointing outcomes. The objective of this study was to evaluate the functional results of emergency hinged or gliding arthroplasty for destroyed PIP joints. A two-center retrospective study was carried out in 24 patients with open and closed trauma of the PIP joint of the fingers from 2007 to 2019. Fifteen hinged silicone implants (NeuFlex®) and nine gliding implants (Tactys®) were used. Pain on a visual analog scale (VAS), stability and total active motion (TAM), grip and pinch strength (Jamar®), QuickDASH and PRWE and satisfaction were assessed, and X-rays were performed. With a mean follow-up of 48 months, 24 patients aged 58 years on average were reviewed. Pain on VAS was 0.2/10, the TAM was 72% of the contralateral side, the QuickDASH was 15.6/100 and the PRWE was 24.5/100. PIP flexion was ≥50% of the contralateral side in 75% of patients. PIP and DIP extensor lag of 9° was significantly larger with the Tactys® than with the NeuFlex®, with no significant difference in the TAM. Three clinodactylies in fingers with the NeuFlex® and three reducible swanneck deformities in fingers with the Tactys® were noted. Three-quarters of patients were very satisfied or satisfied with the outcome. Emergency PIP arthroplasty with Tactys® seems to provide functional results that are as good as with NeuFlex®. Clinodactyly was found with NeuFlex® use. A significant PIP and IPD extensor lag of 9° and swan-neck deformities were found with Tactys® without significant functional impairment.
