RESUMO
BACKGROUND: Conventional surgery performed to treat carpal tunnel syndrome (CTS) is associated with complications such as pillar pain or loss of strength. This study aimed to compare the incidence of pillar pain between two techniques at the 3-week and 6-month follow-up and to determine any differences in the recovery of grip strength (GS), pinch strength (PS), and Boston Carpal Tunnel Questionnaire (BCTQ) scores. METHODS: This randomized clinical trial comprised 109 patients of which 55 underwent ligament Z-plasty and 54 underwent conventional surgery (longitudinal section of the transverse carpal ligament without posterior closure). The GS, PS, presence of pillar pain, and BCTQ scores were assessed preoperatively and after 3 weeks and 6 months. RESULTS: The incidence of pillar pain after 3 weeks was lower in patients undergoing Z-plasty than in those undergoing conventional surgery (25.5% vs. 44.4%, p = 0.04). Moreover, the absolute change in the PS after 3 weeks (p = 0.01) and GS after 6 months (p = 0.05) and the absolute and relative changes in the PS after 6 months (p = 0.008 and p = 0.01, respectively) were significantly higher in the Z-plasty group than in the conventional surgery group. CONCLUSIONS: Z-plasty is a valid surgical procedure for treating CTS. It is associated with a lower incidence of pillar pain and better recovery of postoperative strength compared to the conventional surgical technique, with both techniques showing similar results in CTS recovery.
RESUMO
Background: Glenohumeral arthropathy after surgery for traumatic shoulder instability is a condition whose etiology and long-term course are still unknown. Purpose: To evaluate the risk factors for the onset of arthropathy and to assess the relationship between the degree of arthropathy and final outcomes. Study Design: Case series; Level of evidence, 4. Methods: We included patients who underwent surgery for a shoulder instability at a single institution between 2000 and 2004. The following variables were studied for relationship with functional outcomes: sex, age, body mass index, smoking at the time of surgery, number of episodes of shoulder dislocation, and time from first dislocation to surgery. The number of anchors used and their position were also evaluated. Functional outcomes were assessed using the Constant-Murley, Western Ontario Shoulder Instability Index, and Rowe scores, and results were compared with the onset of arthropathy according to Buscayret classification. Spearman and Pearson correlations were performed for the association between glenohumeral arthritis (Buscayret grade) and the study variables, the Mann-Whitney U test and Student t test were used to compare outcome scores with the study variables, and the Kruskal-Wallis test was used to compare Buscayret grade and outcome scores. Results: A total of 26 shoulders in 25 patients were analyzed, finding a high rate (54%) of arthropathy at a minimum follow-up of 16 years. Patients with Buscayret grade 4 had the worst functional results (P = .007). However, 80% of patients with Buscayret grade ≤3 had excellent Constant-Murley scores. A significant relationship was found between degree of arthropathy and patients who were smokers before surgery (P < .01). No relationship was found between the onset of arthropathy and the other variables analyzed. Conclusion: Postinstability glenohumeral arthropathy was not correlated with functional outcomes except in those patients with advanced arthroplasty (Buscayret grade 4). A direct relationship was found between smoking before surgery and the onset of glenohumeral arthropathy.
RESUMO
The objective of this article is to describe intraoperative pulmonary embolism during shoulder arthroscopy in a patient with previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Further, we describe how the pandemic has influenced the population by increasing the rate of embolisms. Awareness of such cases will help to increase knowledge regarding SARS-Cov-2 and to determine if such patients should receive routine antithrombotic prophylaxis.
RESUMO
BACKGROUND: There is still little information about the long-term results of clinical and radiological evolution in patients older than 65 years with complex proximal humerus fractures (CPHF) treated acutely with reverse shoulder arthroplasty (RSA). The aim of this paper was to evaluate function and results 7 years after surgery. MATERIAL AND METHODS: A prospective cross-sectional cohort study was designed for this purpose. Patients who underwent RSA surgery during 2012 because of a CPHF were included. The surgical approach was randomized (deltopectoral vs anterosuperior). Functional activity, evolution of tuberosities and evidence of scapular notching 7 years after surgery were analyzed. RESULTS: After evaluating 32 patients, the Constant score improved from 64.83 in the first year to 69.54 at 7 years postoperative. Results were independent of the approach used. Functional outcomes were poorer in patients with scapular notching and when tuberosities were resorbed or displaced. CONCLUSIONS: At 7 years, function in patients undergoing RSA after CPHF demonstrated improvement in all patients except those who developed scapular notching or when tuberosities did not consolidate in an anatomical position. These results are completely independent of the approach used. LEVEL OF EVIDENCE: III Controlled cohort study.

INTRODUCTION: Obesity is an epidemic nowadays and this fact conditions results in orthopaedic surgery. Very few studies evaluates if obesity is a risk factor for reverse shoulder arthroplasty. The aim of this study is to confirm if there are differences with regard to the outcomes in patients undergoing reverse shoulder arthroplasty according to their body mass index (BMI). MATERIALS AND METHODS: A total of 35 patients were enrolled in the study. Then divided into subpopulations according to their BMI and analyzed twice. First analysis set a division 30 of BMI and second set it in 35. ASES score, major complications, length of the hospital stay, radiolucent lines in components as well as scapular notching were assessed. RESULTS: No major complications were described in our patients. No differences were found related to hospital stay, radiolucent lines or scapular notching. However, in the second analysis (BMI < 35 and ≥ 35) statistical differences were found regarding ASES score. Poorer functional outcomes were described in the type-II obese and morbidly obese population. CONCLUSION: Functional outcomes of reverse shoulder arthroplasty are worse in patients with a BMI over 35.
