Combined lateral extra-articular tenodesis and anterior cruciate ligament reconstruction : risk of osteoarthritis
No full textPurpose Lateral extra-articular tenodesis (LET) procedure, combined with an intra-articular reconstruction of the anterior cruciate ligament (ACL), is used to reduce rotational laxity and the risk of graft failure. However, concern of overtightening of the lateral compartment and subsequent osteoarthritis remains. The aim of this study is to evaluate the degenerative changes in the lateral compartment and to compare the clinical and radiographical results between two LET techniques. Methods Eighty-three patients (86 knees) were retrospectively reviewed at a mean of 67.7 months (range 49-85 months). Forty-two knees had an ACL reconstruction combined with a LET procedure according to the modified Lemaire technique and 44 knees according to the modified Coker-Arnold technique. IKDC, Lysholm, Tegner and VAS scores were used. Osteoarthritis was radiographically evaluated by the Kellgren-Lawrence classification. Results There were 12 patients (28.6%) in the modified Lemaire subgroup and 13 patients (29.5%) in the modified Coker-Arnold subgroup that had doubtful or mild radiologic signs of osteoarthritis. No patients had moderate or severe signs at final follow-up. There was no significant difference in radiological signs of osteoarthritis. In the modified Lemaire subgroup, we report a mean IKDC of 86.31 (+/- 13.794), a mean Lysholm of 87.83 (+/- 12.802) and a mean Tegner of 5.38 (+/- 2.556). In the modified Coker-Arnold subgroup, a mean IKDC of 87.27 (+/- 11.653), a mean Lysholm of 91.89 (+/- 8.035) and a mean Tegner of 5.16 (+/- 2.420) were reported. There were no statistical significant differences between both techniques. In eight patients, a complication was identified, 3 of which had a failure of the ACL reconstruction. Conclusions The chosen LET-technique seems to have minimal effect on both the clinical and the radiographic results. The LET is a safe procedure, and it does not increase the risk of osteoarthritis in the lateral compartment
Relative Femoral Neck Lengthening in Legg-Calvé-Perthes Total Hip Arthroplasty
No full textBackground: Total hip replacement (THR) in patients with a history of Legg-Calv e-Perthes disease can be
a technically challenging procedure due to the distorted hip morphology. We propose a technique in
which THR is preceded by a modified relative femoral neck lengthening (RFNL) procedure. Hereby, we
aim to restore the biomechanical parameters.
Methods: Twenty-eight patients underwent RFNL in preparation of a second-stage THR between
December 2011 and September 2019. The mean age was 38.1 ± 11.4 years. Radiographs were analyzed for
centrotrochanteric distance, lateral displacement of the greater trochanter, and leg length discrepancy to
assess the biomechanical restoration. Complication rate, reoperation rate, and patient-reported outcome
measures were measured.
Results: Mean centrotrochanteric distance increased from 18.7 ± 6.7 mm preoperatively to 1.9 ± 9.0
mm (P < .001) after RFNL and to 11.4 ± 10.4 mm after THR (P < .001). Mean lateral displacement of the
greater trochanter increased from 34.2 ± 8.1 mm preoperatively to 42.4 ± 5.2 mm (P < .001) after RFNL
and to 49.9 ± 8.3 mm after THR (P < .001). Leg length discrepancy decreased from 17.5 ± 10.5 mm to 2.7 ±
2.2 mm after THR (P < .001). Mean Harris Hip Score improved from 56.9 ± 17.6 preoperatively to 89.4 ±
10.7 at the latest follow-up (P < .001). Eight patients (8 hips) postponed THR because of sufficient clinical
improvement, at a mean follow-up of 4.2 ± 2.1 years. Two hips needed a revision RFNL due to non-union
(7.1%), and 1 hip replacement was revised due to a deep infection (5.0%).
Conclusions: RFNL prior to THR in patients with end-stage osteoarthritis following Legg-Calv e-Perthes
disease allows for utilizing regular implants with straight access to the femoral canal, with restored
biomechanics and restoration of leg length. The prominent overhanging greater trochanter is reduced to
prevent postoperative extra-articular impingement.RFNL prior to THR in patients with end-stage osteoarthritis following LCPD allows for utilizing regular implants with straight access to the femoral canal, with restored biomechanics and restoration of leg length
Accentuation of Jonas Rėza's Psalter of 1625
No full textStraipsnyje trumpai apžvelgiama dabartinių kalbų kirčio ženklų istorija – nuo Antikos kalbininko Aristofano Bizantiečio žymėtų akūto, gravio ir cirkumflekso iki Mažvydo Katekizme pažymėto į riestinį cirkumfleksą panašaus ženklo, Baltramiejaus Vilento raštų, D. Kleino gramatikos, J. Rėzos psalmyno ,,Psalteras Dowido“ kirčio ženklų. Išsamiau straipsnyje analizuojamas 1625 m. J. Rėzos psalmyno kirčiavimas, iš graikų perimti kirčio ženklai, paties autoriaus įsivestas kirčio ženklas. Straipsnyje taip pat aptariama Rėzos psalmyne vartotų kirčio ženklų funkcijos, kirčio ženklų vartojimo įvairavimas, sąsajos tarp psalmyno kirčiavimo ir D. Kleino gramatikos Reikšminiai žodžiai: Akūtas; Gravis; Cirkumfleksas; Psalmynas; Lietuvių kalbos istorija; KirčiavimasThis article gives a brief overview of the history of the accent marks of languages from Antiquity linguist Aristophanes of Byzantium marked the acute accent, grave accent and circumflex accent until the sign similar to a tilde-shaped circumflex marked in Mažvydas’ Catechism, and accent signs of Baltramiejus Vilentas’ writings, Daniel Klein‘s grammer, and Jonas Rhesa’s Psalter of David. The article gives a comprehensive analysis of the accentuation made by Jonas Rhesa in the psalter, accent marks taken from Greek, and an accent mark developed by the author himself. The article also discusses the functions of the accent marks used in Rhesa’s psalter, the variation of the usage of accent marks and the interaction between the accentuation of the psalter and D. Klein’s grammer
The peri-articular muscle envelope of the hip (PAME) shows atrophy in patients with refractory groin pain after iliopsoas tenotomy
No full textBackground:
Iliopsoas tenotomy is commonly used to address refractory groin pain resulting from iliopsoas tendinopathy. However, consensus and high-level research on its effectiveness are lacking, with concerns about poor outcomes and complications. Little is known of the effects of iliopsoas tenotomy on the peri-articular muscle envelope of the hip. As the iliopsoas loses its function as the most important hip flexor, the rectus femoris takes over its function, which makes the rectus prone to tendinopathy.
Methods:
A retrospective review of patients (n = 17) undergoing iliopsoas tenotomy between January 2016 and January 2021 was conducted. Pelvic MRI scans were evaluated for muscle quality and volume using a Quartile classification system and cross-sectional area (CSA) measurements. Reliability tests determined the most consistent reference points. Statistical analyses assessed changes between ipsilateral and contralateral sides.
Results:
Following iliopsoas tenotomy, significant reduced cross sectional area was seen in the psoas, iliacus, gluteus minimus, gluteus maximus, rectus femoris, piriformis, obturator internus and obturator externus. Significant increased fatty degeneration was seen in the psoas, iliacus, gluteus minimus, tensor fascia latae, piriformis, obturator internus and obturator externus. The gluteus medius was the only muscle where no difference was seen in the cross sectional area or the fatty degeneration. 15 patients (88%) presented with rectus tendinopathy and 8 of these patients had a surgical debridement of the rectus femoris.
Conclusions:
Our findings reveal that patients with persistent groin pain following iliopsoas tenotomy exhibit changes in the peri-articular muscle envelope, displaying atrophy or fatty degeneration in all muscles except the gluteus medius. Awareness of potential risks is crucial when contemplating iliopsoas tenotomy. Persistent groin pain after iliopsoas tenotomy may be linked to secondary rectus femoris tendinopathy. Caution is recommended in the consideration of iliopsoas tenotomy for patients with pre-existing iliopsoas tendinopathy.The author(s) received no financial support for the research, authorship and/or publication of this article
Jonas, Hobbes e le forme della paura
No full textThis essay aims at clarifying the concept of Jonas’s heuristic of fear. Although it has been severely criticized, fear remains an aspect of his thought which has drawn little attention, particularly regarding the role it plays in the elaboration of the imperative of responsibility. Jonas elaborates a new concept of fear, moulded by the particular form of uncertainty brought about by the technological age. Although critics have interpreted Jonas’ attempt as an ethics founded on irrationality and emotion, the present analysis shows that Jonas affirms a cognitivist theory of fear. The concept of fear he discusses in The Imperative of Responsibility is not an emotion as an immediate physical and psychological reaction, but a form of evaluative thinking that is part of responsibility. In order to illustrate form and function of fear in Jonas thought, I will refer to the meanings of fear in Hobbes, an author Jonas himself refers to
