Despite the relatively high frequency of Achilles ruptures, there is no general consensus on the optimal treatment method. A general trend toward more patients being treated nonoperatively has emerged recently with the advent of functional rehabilitation. However, much of the recent data on this subject has been highly variable. This systematic review focused on Achilles tendon rupture (ATR) treatment outcomes, with a focus on rerupture and complication rates. This systematic review specifically focused on articles regarding ATR treatment that also included rerupture and complication rates. Treatments were divided into three categories: open minimally invasive, open standard, and nonoperative. Bivariate analyses were performed to compare complication and rerupture rates among pairs of treatment options, as well as between early weight bearing versus immobilization. There was significantly higher complications for minimally invasive compared to nonoperative treatment (risk ratio [RR] = 4.4154; p < 0.05), lower complication rates for minimally invasive compared to open treatment (RR = 0.3231; p < 0.05), and higher complications for open standard compared to nonoperative treatment (RR = 5.6350; p < 0.001). There were significantly lower rerupture rates in minimally invasive compared to nonoperative treatment (RR = 0.4085; p < 0.001), a significantly lower rerupture rate in nonoperative treatment compared to open treatment (RR = 0.2282; p < 0.001), and no significant difference in rerupture rates when comparing minimally invasive to open standard treatment. We found that operative treatment is associated with fewer reruptures and more complications than a nonoperative approach. Minimally invasive surgery appears to be associated with a lower rate of complications than open operative treatment., (© 2022 Orthopaedic Research Society. Published by Wiley Periodicals LLC.)

Purpose: The aim of this systematic review and meta-analysis was to compare re-rupture rates, complication rates, functional outcomes, as well as return to work (RTW)/sport (RTS) among different rehabilitation protocols following operative treatment of acute Achilles tendon ruptures., Methods: Systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Five databases were searched for randomized controlled trials (RCTs) comparing at least two rehabilitation protocols following surgical repair of acute Achilles tendon ruptures. Rehabilitation protocols were classified as a variation of either non-weightbearing (NWB) or weightbearing (WB) and immobilization (IM) or mobilization (M). The data collection consisted of re-ruptures, complications, and RTW/RTS., Results: Out of 2760 studies screened, 20 RCTs with 1007 patients were eligible. Fourteen studies included a group consisting of WB + M (Group 1), 11 of WB + IM (Group 2), 3 of NWB + M (Group 3), and 13 of NWB + IM (Group 4). Outcome parameters available for a meta-analysis were re-ruptures, complications, RTW, and RTS. Re-ruptures overall occurred in 2.7%, with prevalences ranging between 0.04 and 0.08. Major complications occurred in 2.6%, with prevalences ranging between 0.02 and 0.03. Minor complications occurred in 11.8% with prevalances ranging between 0.04 to 0.17. Comparing the odds-ratios between the four different groups revealed no significant differences with overall favourable results for group 1 (WB+M)., Conclusion: Early functional rehabilitation protocols with early ankle M and WB following surgical repair of acute Achilles tendon ruptures are safe and they apparently allow for a quicker RTW and RTS and seem to lead to favourable results.

Introduction: Amyloidosis is a heterogeneous group of diseases that most often presents with advanced cardiac pathology. Another presentation of the disease can include symptoms consistent with carpal tunnel syndrome; however, the true incidence of amyloidosis in patients with carpal tunnel syndrome remains unclear., Methods: We performed a retrospective chart review on all patients who underwent an open carpal tunnel release, with tenosynovium biopsy by a single surgeon between 01/2000 and 12/2018. Samples were stored in formalin following hematoxylin-eosin or congo red staining. A total of 199 patients were excluded for incomplete records, and carpal tunnel release performed for traumatic or infectious etiologies. Histologic findings of the attending pathologist were examined and categorized as follows: amyloidosis, fibrous tissue, tenosynovitis/inflammation edematous, benign tenosynovium, and gout., Results: Exactly 898 open carpal tunnel releases were performed, and 699 patients were included for final analysis. In all patients, biopsies for histology with hematoxylin-eosin (HE) staining were taken; in those HE stains where amylogenic proteins were suspected (73 or 10.4%), a subsequent congo red staining was additionally performed which confirmed the diagnosis of amyloidosis in 10 patients (1.4% of the carpal tunnel procedures). Overall, 10 patients were identified and constituted 1.4% of all HE stains (n = 10/699) and 13.7% of all congo red stains (n = 10/73)., Conclusion: Our results suggest that the incidence of amyloidosis in the general CTS patient population may be as high as 1.4% with routine screening by synovial biopsy and the diagnosis should be considered as a potential cause. Level of Evidence: III, retrospective study., (© 2021.

Background: Flexor pollicis longus (FPL) tendon lacerations typically occur via sharp mechanisms such as knife injury. When the injury is chronic, it may be difficult to perform a tension free repair, and tendon lengthening may be required. This article proposes a technique that transposes the proximal tendon stump over the thenar eminence subcutaneously, out of the carpal tunnel, in an attempt to gain additional tendon length by eliminating the sharp turn the FPL takes. Methods: A total of 17 cadaveric hands were used. The FPL tendon was identified and affixed to soft tissue in the distal forearm as well as at the thumb metacarpophalangeal (MP) joint with hypodermic needles. The tendon was then transected at the level of the MP joint of the thumb, removed from the carpal tunnel, and transposed on top of the thenar eminence to reach where it had been transected. The length gained by transposing the tendon was recorded by measuring the overlap of the tendon ends at the MP joint. Results: The mean amount lengthened was 7.6 mm with a standard deviation of 2.4 mm, ranging from as little as 5 mm to as high as 13 mm. Conclusions: To our knowledge, transposition of FPL tendon is a novel technique that has not been reported. Based on our cadaveric study, it can be used to bridge gaps between approximately 5 mm and 10 mm. Clinically, this amount of gap could potentially be more easily managed by simply making the repair tighter than usual as opposed to transposing the tendon.

Our research aims to assess the change in the grade of responsiveness using the Hunt and Hess score as well as the modified ranking scale in patients suffering from anterior communicating artery rupture. We retrospectively analyzed data from 11-patients who suffered from an anterior communicating artery aneurysm rupture that caused a subarachnoid hemorrhage. Severity was assessed using the Hunt and Hess scale grade and modified ranking scale. Anterior communicating artery rupture caused a subarachnoid hemorrhage in 40.81% of all aneurysm ruptures that took place at the Circle of Willis. Unfortunately, 4-patients deceased (3.4%) at a median age of 52-years (range 34-75-years), three of which deceased after coiling and one after clipping. In 71-patients (61.2%) endovascular coiling was performed - 33-males and 38-females - and in the remaining 45-cases, (38.8%) clipping was indicated - 24-males and 21-females. Overall, the pre-interventional median Hunt and Hess scale was 2, which remained after the intervention. When relating the outcome score to the intervention performed, we found that the Hunt and Hess scale score was 3 before coiling and 2 before clipping, whereas afterward, there was a slight increase to 2 and 2, respectively. The modified ranking scale was 2 after clipping, respectively, coiling ( P = 0.218). No significant differences were observed between the different groups. Our results show that clipping is as effective as coiling in terms of the Hunt and Hess scale and the rate of mortality in the short-term., Competing Interests: The authors declare that they don't have any conflict of interest related to this study., (© 2020 Bäcker et al.
