Project description:The olecranon bursa is very commonly involved in tophaceous gout because of the tendency of monosodium urate crystals to deposit in superficial structures with low temperatures. Surgery is indicated if the olecranon tophus is recalcitrant to medical treatment. Open surgery requires a long incision over the tophus and may lead to wound complications. Endoscopic debridement of the tophus can reduce the risk of wound complications. In this Technical Note, the technical details of endoscopic decompression of an olecranon tophus are described. This endoscopic technique also allows debridement of tophus infiltration of the triceps tendon.

Project description:Tophaceous deposition of tendon can result in spontaneous patellar tendon rupture. Surgical therapy may be needed to control symptoms and prevent tendon rupture. Open debridement of the lesion requires a lengthy incision over the lesion; this may result in symptomatic scar adhesion of the patellar tendon or an unhealed wound with persistent tophaceous discharge. Moreover, the other part of the patellar tendon cannot be examined through the incision. We describe a technique for endoscopic resection of a gouty tophus of the patellar tendon. It has the advantage of small incisions away from the lesion and tendon and minimizes wound problems. The whole patellar tendon can be examined endoscopically.

Project description:Morton neuroma is an entrapment of the intermetatarsal nerve by the deep intermetatarsal ligament. It is usually treated conservatively. Surgery is considered if there is recalcitrant pain that is resistant to conservative treatment. The surgical options include resection of the neuroma or decompression of the involved nerve. Decompression of the nerve by release of the intermetatarsal ligament can be performed by either an open or minimally invasive approach. We describe 2-portal endoscopic decompression of the intermetatarsal nerve. The ligament is released by a retrograde knife through the toe-web portal under arthroscopic guidance through the plantar portal.

Project description:We present a 24-year-old male who developed an infected hematoma that resulted in sciatic nerve injury after he underwent an endoscopic sciatic nerve decompression. He underwent urgent hematoma evacuation and cultures speciated as Salmonella. At 4 months' follow-up, the patient's nerve had improved motor and sensory function. This case highlights the importance of obtaining appropriate hemostasis at the end of an endoscopic sciatic nerve decompression.

Project description:The perception of the body and its parts has traditionally been studied using the conscious body image. Here, we determine the implicit representation of the hand. Participants were sequentially shown two life-size images of either the dorsal or palmar surface of their hand. In one interval either the horizontal or vertical dimension of the image was varied using an adaptive staircase, while the other interval contained the full-size, undistorted image. Participants reported which image most closely matched their hand. The staircase honed in on the distorted image that was equally likely to be judged as matching their own hand as the accurate image. The implicit representation was taken as midway between these two images. The experiment was repeated with different hand orientations. Perceived width depended on the orientation, with differences found between the upright and right orientations. Interestingly, the perceived length of the dorsum and palm were different from each other-length of the dorsum was overestimated whereas palm length was perceived accurately. This study reveals distortions of the implicit representation of the hands in healthy individuals.

Project description:ObjectiveCervical osseous foraminal stenosis (COFS) results from the uncinate process and facet hyperostosis. Currently, the optimal surgical technique for the treatment of COFS remains controversial.Materials and methodsPatients with COFS presenting radiculopathy underwent posterior endoscopic cervical foraminotomy by the circumferential decompression technique. The neck disability index (NDI), the visual analogue scale (VAS), and the modified MacNab criteria were used to evaluate the outcomes. In addition, the range of motion (ROM) and the slippage distance between the operated vertebrae in flexion-extension position were measured to evaluate the stability of the cervical spine.ResultsThere were 24 consecutive patients in the study. The mean follow-up period was 16.2 months (range: 12-26 months). The NDI and VAS scores for arm/neck pain improved significantly from preoperatively to the last follow-up. The satisfaction rate by modified MacNab criteria was 91.7% on the third postoperative day and 100% on the day of final follow-up. There were no significant differences in intervertebral ROM or slippage distance between the last follow-up and preoperatively (P = 0.968, P = 0.394). Arm pain occurred in one patient, and sustained fingers numbness in two patients, but these symptoms resolved at the last follow-up.ConclusionsPosterior endoscopic cervical foraminotomy by the circumferential decompression technique is a safe and effective treatment for COFS. Moreover, it preserves the stability and physiological mobility of the cervical spine.

Project description:Endoscopic spine surgery for the treatment of degenerative spinal diseases from lumbar to cervical spine has accelerated over the past 2 decades. Posterior endoscopic cervical discectomy (PECD) has been described as a safe, effective, and minimally invasive procedure for cervical radiculopathy or even part of the myelopathy. This procedure also has been validated with comparable outcomes to open and microscopic surgery. Radiculopathy due to foraminal disc herniation or foraminal stenosis should be the optimum indications of this procedure. Intraoperative 3-dimensional navigation can help surgeons to get quick and great quality guidance for endoscopic surgeons. In this review, we will focus on the technical details and evidence-based results of PECD which is a promising procedure for cervical radiculopathy with the advantages of a minimally invasive method.

Project description:Core decompression is a joint-preserving surgery feasible in early-stage avascular necrosis of the femoral head. An arthroscopically/endoscopically aided development of this procedure is presented to overcome some drawbacks of the standard technique. Conventional imaging may underestimate the articular damage; thus a preliminary hip arthroscopy helps to identify those patients with significant joint damage, who might not benefit from the procedure. The standard fluoroscopically guided core decompression does not allow precise targeting or reliable debridement of the lesion. Tunnel endoscopy helps the surgeon to aim precisely at the lesion and to debride it thoroughly, with accurate visual verification. In conclusion, the arthroscopic-endoscopic assistance may lead to more accurate patient selection, more precise targeting, and more complete debridement, with no apparent disadvantages.

Project description:BackgroundTo describe the surgical technique and assess the clinical efficacy and safety of modified endoscopic transnasal orbital apex decompression in the treatment of dysthyroid optic neuropathy.MethodsIn this retrospective research, forty-two subjects (74 orbits) who underwent modified endoscopic transnasal orbital apex decompression for the treatment of dysthyroid optic neuropathy were enrolled. Preoperative and postoperative best-corrected visual acuity (BCVA), visual field mean deviation (MD), Hertel exophthalmometry, and new onset diplopia were assessed before and after the intervention. The Wilcoxon test was used for differential analysis. Linear mixed-models' analyses were conducted to assess the potential predictors for BCVA change.ResultsPostoperatively, the mean BCVA improved from 0.70 ± 0.62 logMAR to 0.22 ± 0.33 logMAR. BCVA significantly improved in 69 eyes (93%), remained stable in 4 eyes (5%) and deteriorated in 1 eye (1%). MD of visual fields improved from -13.73 ± 9.22 dB to -7.23 ± 7.04 dB. Proptosis decreased from 19.57 ± 3.38 mm to 16.35 ± 3.01 mm. Preoperative BCVA, MD of visual fields and medical rectus diameter were independent factors associated with improvements in BCVA (P < 0.05) by linear mixed-models' analyses. Eighteen patients (42.9%) developed new diplopia postoperatively.ConclusionModified endoscopic transnasal orbital apex decompression effectively restores vision in dysthyroid optic neuropathy.

Project description:ImportanceCarpal tunnel release (CTR) technique may influence the likelihood of revision surgery. Prior studies of revision CTR following endoscopic CTR (ECTR) compared with open CTR (OCTR) have been limited by sample size and duration of follow-up.ObjectiveTo estimate the incidence of revision CTR following ECTR compared with OCTR in a national cohort.Design, setting, and participantsThis retrospective cohort study used data from the US Veterans Health Administration. Participants included all adults (age ≥18 years) undergoing at least 1 outpatient CTR from October 1, 1999, to May 20, 2021. Data were analyzed from May 21, 2021, to November 27, 2023.ExposureIndex CTR technique.Main outcomes and measuresThe primary outcome was time to revision CTR, defined as repeat ipsilateral CTR during the study period. Secondary outcomes were indications for revision, findings during revision, and additional procedures performed during revision.ResultsAmong 134 851 wrists from 103 455 patients (92 510 [89.4%] male; median [IQR] age, 62 [53-70] years) undergoing at least 1 CTR, 1809 wrists underwent at least 1 revision at a median (IQR) of 2.5 (1.0-3.8) years. In competing-risks analysis, the cumulative incidence of revision was 1.06% (95% CI, 0.99%-1.12%) at 5 years and 1.59% (95% CI, 1.51%-1.67%) at 10 years. ECTR was associated with increased hazard of revision CTR compared with OCTR (adjusted hazard ratio [aHR], 1.56; 95% CI, 1.34-1.81; P < .001). The risk difference for revision CTR associated with ECTR compared with OCTR was 0.57% (95% CI, 0.31%-0.84%) at 5 years (number needed to harm, 176) and 0.72% (95% CI, 0.36%-1.07%) at 10 years (number needed to harm, 139). Regardless of index CTR technique, the most common indication for revision was symptom recurrence (1062 wrists [58.7%]). A reconstituted transverse carpal ligament (TCL) was more common after ECTR compared with OCTR, whereas scarring of the overlying tissues and of the median nerve itself were more common following OCTR. Incomplete transverse-carpal-ligament release was observed in 251 of the wrists undergoing revision CTR (13.94%) and was more common among revisions following ECTR (odds ratio, 1.62; 95% CI, 1.11-2.37; P = .01).Conclusions and relevanceIn this cohort study of revision CTR in the Veterans Health Administration, ECTR was associated with increased risk of revision compared with OCTR, but the absolute risk was low regardless of technique. Intraoperative findings at revision varied significantly according to index CTR technique.
