RESUMEN

BACKGROUND: Rotator cuff disorders include a broad spectrum of pathological conditions including partial-thickness and full-thickness tears. Studies have shown partial-thickness rotator cuff tear (PTRCT) prevalence to be twice that of full-thickness tears. In the working population, PTRCTs are one of the most common causes of shoulder pain and often result in occupational disability due to pain, stiffness, and loss of shoulder function. Treatment of PTRCTs remains controversial. The purpose of this study was to consolidate the existing high-quality evidence on best management approaches in treating PTRCTs using both nonoperative and operative approaches. METHODS: A scoping review with best evidence synthesis was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. MEDLINE (OVID), EMBASE (OVID), Cochrane Library (Wiley), SCOPUS, Web of Science Core Collection, CINAHL Plus with Full Text (EBSCOhost), PubMed Central, and Science Direct were searched from 2000 to March 3, 2023. Level 1 studies, and systematic reviews and meta-analyses that included level 1 and 2 studies, were included. RESULTS: The search yielded 8276 articles. A total of 3930 articles were screened after removing 4346 duplicates. Application of inclusion criteria resulted in 662 articles that were selected for full-text review. Twenty-eight level 1 studies, 1 systematic review, 4 meta-analyses, and 1 network meta-analyses were included in the best evidence synthesis. Nonoperative strategies included injections (ie, platelet-rich plasma, corticosteroid, prolotherapy, sodium hyaluronate, anesthetic, and atelocollagen), exercise therapy, and physical agents. Operative interventions consisted of débridement, shaving of the tendon and footprint, transtendon repair, and traditional suture anchor repair techniques with and without tear completion. Both nonoperative and operative strategies demonstrated effectiveness at managing pain and functional outcome for PTRCTs. The evidence supports the effectiveness of surgical intervention in treating PTRCTs regardless of arthroscopic technique. CONCLUSION: The results of this scoping review do not support superiority of operative over nonoperative management and suggest that both strategies can be effective at managing pain and functional outcome for PTRCTs. Surgery, however, is the most invasive and costly approach, with the highest risk of complications such as infection. Other variables such as patient expectation, treating practitioner bias, or preference may change which modalities are offered and in what sequence.

RESUMEN

OBJECTIVES: To determine whether magnetic resonance imaging (MRI) with metal artifact reduction sequencing is superior to conventional knee MRI in the evaluation of an injured anterior cruciate ligament (ACL) graft, where visualisation on conventional MRI can be limited by the metal artifact from fixation devices. METHODS: Eighteen patients underwent conventional MRI sequence (proton density fat saturated [PDFS]) and two types of metal artifact reduction sequencing MRI (WARP, slice encoding for metal artifact correction (SEMAC); Siemens) following a secondary injury to their ACL reconstructed knee. Six raters with experience in knee MRI evaluation reviewed sagittal PDFS, WARP, and SEMAC sequences, providing semi-quantitative grades for visualisation and diagnostic confidence assessing the ACL, posterior cruciate ligament , menisci, tibial and femoral tunnel margins, and articular cartilage. Intra-class correlation coefficients for inter-rater reliability were evaluated. The 6-rater mean scores for the visualisation and diagnostic confidence derived from each sequence were compared using the Friedman test for multiple paired samples. RESULTS: No statistically significant difference in the ACL visualisation among the sequences was found (p â€‹= â€‹0.193). Further, a subgroup analysis was performed in cases evaluated as "moderately blurry" or "indistinct ACL visualisation" on PDFS (58% of cases). SEMAC significantly improved diagnostic confidence in ACL visualisation (p â€‹= â€‹0.041) and ACL graft rupture (p â€‹= â€‹0.044) compared to PDFS. There was no statistically significant difference in the inter-observer reliability between sequences. The WARP sequence added 2.84 â€‹± â€‹0.69 â€‹min, while SEMAC added 2.95 â€‹± â€‹0.40 â€‹min to the standard knee MRI scan time. CONCLUSION: use of the SEMAC metal reduction sequence significantly improved diagnostic accuracy and confidence in the detection of ACL graft rupture in cases where the ACL was moderately blurry or indistinct on the PDFS sequence. This sequence should be considered as an adjunct to conventional PDFS in cases where graft visualisation is limited by the metal artifact from fixation devices. LEVEL OF EVIDENCE: III.

RESUMEN

Knee dislocation with a common peroneal nerve injury is a serious problem. A case of multi-ligamentous knee injury with the unusual and interesting finding of a common peroneal nerve rupture incarcerated within the knee joint is presented. MRI and arthroscopic images are used to document this occurrence. To date, there are no published reports of a similar finding in the English orthopaedic literature. Level of evidence IV.

RESUMEN

Cases of isolated spontaneous celiac trunk dissections have been appearing in the literature more recently with the increased availability of high-resolution computerized tomography angiograms. We report a unique case of this entity. A 48-year-old woman presented with acute abdominal pain that radiated to the back and worsened with breathing. This was diagnosed as a celiac trunk dissection by computerized tomography angiogram. She was treated conservatively with antihypertensive medications, anticoagulants, and opioid medication for pain control.

RESUMEN

BACKGROUND: Intraneural ganglion cysts are rare, benign, mucinous lesions that occur within neural sheaths and are thought to involve cystic fluid exiting from nearby synovial joints. They often present as tender masses causing paresthesias in the distribution of the involved nerve, muscle weakness or cramping, or localized or referred pain. CASE DESCRIPTION: We present a case of a patient who initially presented with foot drop due to an intraneural ganglion cyst of the common peroneal nerve. This cyst was successfully treated using ultrasound guidance to aspirate the cyst and inject corticosteroid to prevent further inflammation. LITERATURE REVIEW: Standard of care has previously involved surgical resection, but this has been associated with a high frequency of recurrence. Due to the risks of nerve and vessel damage, there have been efforts to find alternative ways of resolving these cysts. PURPOSES AND CLINICAL RELEVANCE: Aspiration and injection of corticosteroid is a useful and minimally invasive alternative to surgery for managing intraneural ganglion cysts.

RESUMEN

Solid lesions of the pancreas represent a heterogeneous group of entities that can be broadly classified as either neoplastic or nonneoplastic. Neoplastic lesions include pancreatic adenocarcinoma, pancreatic neuroendocrine tumor, solid pseudopapillary tumor, pancreatoblastoma, pancreatic lymphoma, metastases to the pancreas, and rare miscellaneous neoplasms. Nonneoplastic lesions include focal pancreatitis, fatty infiltration-replacement, intrapancreatic accessory spleen, congenital anomalies such as prominent pancreatic lobulation and bifid pancreatic tail (pancreatic bifidum), and rare miscellaneous lesions (eg, pancreatic sarcoidosis, Castleman disease of the pancreas). A variety of imaging modalities are available for assessing these solid lesions, including ultrasonography (US), computed tomography (CT), magnetic resonance imaging, endoscopic US, and hybrid nuclear imaging techniques such as single photon emission computed tomography-CT and positron emission tomography-CT, each of which has its own strengths and limitations. Accurate diagnosis can be challenging, and use of a multimodality imaging approach is often helpful in equivocal or complex cases. Knowledge of relevant clinical information and key radiologic features is essential for confident lesion characterization and differentiation.

RESUMEN

PURPOSE: To assess the technical success and complications of Angio-Seal vascular closure device in antegrade common femoral artery (CFA) punctures. METHODS: Over a 14-month period, 55 patients (37 men; age range 37-94 years) underwent antegrade CFA Angio-Seal placement at a single center; the clinical data and angiograms were reviewed retrospectively. A total of 56 antegrade CFA punctures were made for hemostasis; 6-F Angio-Seal devices (40 model STS and 12 model VIP) were deployed in 52 CFAs, and 8-F Angio-Seal devices were deployed in 4. RESULTS: The technical success rate was 98.2% (55/56). Two (3.6%) patients developed small, non-expanding hematomas (<5 cm) during deployment of the device. There was 1 episode of device/operator failure, presumably due to extravascular deployment within soft tissue. None of the patients developed pseudoaneurysm, arterial injury, or large hematomas requiring transfusion. Small calcified plaques at the puncture site did not influence the outcome. CONCLUSION: This series suggests that Angio-Seal may be a safe and effective device for hemostasis in antegrade CFA punctures. Further randomized trials testing its risk-benefit balance in comparison to standard manual compression are warranted.
