“…Alternatively, the suture is knotted around a tube or rod that remains in the loop during the test (Rosin & Robinson, 1989). The clinical relevance of the ear technique has been questioned as the loop can pull through and the load is applied to the physician's side and not the patient's side of the knot (Huber et al, 1999;Thacker et al, 1975).…”

“…The loop thus formed is removed and positioned around two right-angled rods that are placed in the jaws of a tensile tester (Annunziata et al, 1997;Bayraktar & Hockenberger 2001;Herrmann, 1971;Holmlund, 1974;Huber et al, 1999;Mishra, Cannon, Lucas, & Belzer, 1997;Nilsson, 1982;van Rijssel et al, 1989). While the load is applied to the patient's side, failure of the suture is usually by knot slippage, rather than knot failure.…”

“…In the cut-loop method a loop is formed as in the loop method, however the knotted suture loop is cut opposite the knot and each newly formed end is placed in a jaw of a tensile tester (Huber et al, 1999;Lewis, Milthorpe, & Bellenger, 1997;Rodeheaver, Green, Odum, Bussard, & Edlich, 1998;Rosin & Robinson, 1989;Schiller, Stone, & Gupta, 1993;Tera & Aberg, 1976a;Thacker et al, 1975). Although the load is applied to the patient's side, the cutloop technique usually measures knot slippage rather than knot strength, the measured values being affected by the length of the ears.…”

There is no international standard method for measuring the strength of knotted suture materials, and although several methods have been published, there has been minimal investigation on the effects of test variables on measured properties (e.g. speed, gauge length, and knot tensioning force). Methods investigated in this work were the "ear method" (with and without a rod inside the loop), and the "cut-loop and ear method". The test environment, material, and type of knot were constant. Effects of varying gauge length, test speed, and knot-tensioning force on tenacity and strain were investigated and compared with data for nonknotted sutures. Different values of tenacity and strain were evident for the different test methods; lower values of tenacity for specimens with shorter gauge lengths and tested at greater speeds; lower values of strain for specimens with longer gauge lengths and tested at greater speeds. Thus, tensile properties of suture materials tested at one gauge length or one test speed, as widely reported in the literature, may be misleading. Knot tensioning force neither affect tenacity nor strain.

Cranial cruciate ligament rupture (CCLR) is one of the most important orthopedic conditions in dogs, leading to joint instability, pain, osteoarthritis and eventually to meniscal injuries. Several surgical techniques have been described to reestablish joint stability following CCLR, including extracapsular procedures. This study compared the biomechanical effects of two extracapsular stabilization techniques (lateral fabello-tibial suture -LFTS, and modified retinacular imbrication technique -MRIT) using nylon leader line following experimental CCLR in cadaver dogs. Twenty canine cadaveric stifles were used. Joint stiffness, cranial and caudal tibial displacement were evaluated in 4 different experimental scenarios: intact stifle, stifle with CCLR, CCLR treated with lateral fabello-tibial suture (LFTS), and CCLR treated with modified retinacular imbrication technique (MRIT). Results: Mean cranial tibial displacement increased progressively from intact to MRIT, LFTS and CCRL stifles. MRIT resulted in less caudal drawer motion than LFTS. Joint stiffness did not differ significantly between LFTS and MRIT treated stifles. Conclusion: LFTS and MRIT increase joint stability but MRIT is more effective; however none of the techniques studied was able to restore original intact stifle stiffness. Clinical implications of the results presented remain to be determined but kinetic gait analysis studies are warranted to determine whether this biomechanical advantage translates into improved hind limb function in dogs.

ResumoA ruptura do ligamento cruzado cranial (RLCCr) é uma das principais afecções ortopédicas em cães e resulta na instabilidade do joelho, dor, desenvolvimento de osteoartrose, podendo também causar lesão de menisco. Com o intuito de restabelecer a estabilidade da articulação, muitas técnicas são utilizadas, dentre elas, as extracapsulares. O objetivo do presente trabalho foi realizar a avaliação biomecânica de duas dessas técnicas em 20 joelhos de cadáveres de cães utilizando-se fio de náilon leader line. Nestas peças foram avaliados a rigidez articular e o deslocamento tanto cranial quanto caudal da tíbia em quatro situações distintas: joelho íntegro; joelho com RLCCr e sutura fabelo-tibial lateral (SFTL); joelho com RLCCr e sutura fabelo-tibial lateral e medial (SFTLM); e por fim, o joelho com RLCCr sem as técnicas de estabilização. Houve diferença no deslocamento cranial entre todas as situações, sendo em ordem crescente, o joelho integro, com SFTLM, com SFTL e por fim, o joelho com RLCCr não estabilizado. Na comparação da presença de movimento de gaveta caudal a técnica de SFTLM apresentou menor deslocamento que a técnica de SFTL. Com relação à rigidez tanto cranial quanto caudal, as duas técnicas não apresentaram diferença. As duas técnicas testadas diminuem a instabilidade do joelho, sendo a SFTLM mais efetiva, e nenhuma delas restaurou a rigidez articular de um joelho íntegro. As implicações clínicas dos resultad...

“…capitis femoris'in görevini yapacak yapay bir bağ oluşturulurken, bu amaçla farklı dikiş materyalleri kullanılmaktadır. En çok kullanılan dikiş materyalleri multiflament poliester, monofilament polipropilen ve monofilament poliamid'dir (cerrahi naylon dikiş materyali) (2,7,10,12). Dikiş materyalleri ile ilgili en önemli komplikasyon, bunların özellikle erken dönemde kopmaları sonucu şekillenen reluksasyonlardır (%18,5 -%25) ve genellikle operasyondan sonra 2. ve 8. haftalar arasında oluştuğu bildirilmiştir (3,5,10).…”

Özet: Bu çalışmada koksofemoral luksasyonların toggle pin uygulaması ile sağaltımında, monofilament naylon balıkçı misinasının intra-artiküler stabilizasyon amacıyla kullanımının klinik ve radyografik olarak sonuçlarının değerlendirilmesi amaçlandı. Koksofemoral luksasyonların sağaltımında uygulanan toggle pin tekniği, ekstremitenin erken dönemde fonksiyonel olarak iyileşmesi arzulanan olgularda olumlu sonuçlar vermektedir. Kliniğimize arka ekstremite topallığı ile getirilen 14 köpek ve 11 kedi çalışma materyalini oluşturdu. Bir kedi ve bir köpekte caudoventral, diğer olgularda ise craniodorsal yönde belirlenen koksofemoral luksasyonların sağaltımı sonrasında, caput femoris'te kırık ve operasyon bölgesinde osteomyelitis belirlenen iki olgu dışında klinik ve radyografik sonuçlar fonksiyonel iyileşme açısından tatmin edici olmuştur. Sonuç olarak, ekstra-artiküler stabilizasyon amacıyla birçok çalışmada denenmiş olan monofilament naylon balıkçı misinasının intra-artiküler stabilizasyon amacıyla kullanımı, gerek koksofemoral eklem stabilitesinin dayanıklılığı açısından gerekse operasyondan sonra yapılan klinik ve radyografik değerlendirme-lerde vücutta reaksiyon yaratmaması nedeniyle uygundur.Anahtar sözcükler: Balıkçı misinası, kalça eklemi, kedi, köpek, luksasyon, toggle pinApplication and clinical assessment of toggle pin with monofilament nylon sutur material for treatment of coxofemoral joint luxation in dog and cat Summary:In this study, we intended to evaluate clinical and radiographical results of monofilament nylon fishing line usage in intra-articular stabilization of hip joint via toggle pin technique. Toggle pin technique for treatment of coxofemoral luxations generally results in early functional recovery of the extremity. Fourteen dogs and 11 cats were referred to our clinic with hind limb lameness constituted cases of our study. After treatment of caudoventral luxations in a cat and a dog, and of craniodorsal luxations in remaining cases, results of treatment of cases were satisfactory, except for two cases, one had fracture of femoral head and other had osteomyelitis at the operation site. In conclusion, intra-articular application of monofilament nylon fishing line which has been used in extra-articular stabilization of joint is convenient because of strength of repaired joint stability and no body reaction against suture material had been observed in postoperative clinical and radiographical examinations. Key words: Cat, dog, fishing line, hip joint, luxation, toggle pin * Aynı başlıklı tez çalışmasından özetlenmiştir. GirişKoksofemoral luksasyon, kalça eklemini oluşturan caput femoris'in acetabulum'dan ayrılarak, farklı yönlerde yer değiştirmesidir. Koksofemoral eklem luksasyonları, küçük hayvanlarda diğer eklemlere göre (yaklaşık %90) en sık şekillenen luksasyon tipidir (4,15,18).Luksasyonların büyük bir çoğunluğunun (yaklaşık %75) craniodorsal doğrultuda oluştuğu bilinmektedir.
