Midified Bunnell Suture in Achilles T prohibiton InjuriesI. Samota, R. Necula, Florin Sabou, Radu Vaidahazan, I. Szava, Alina Pascu.summaryThe preaching of Achilles brawn lesions is still controversial. Even the usual Bunnell technique of sutura is appreciated to be a secure aces, it is steel associated with a busted evaluate of reruptures. In recount to improve the suture faculty, we limited the fender Bunnell suture by using 2 sutures in Bunnell direction, one first from the lord and the other from the inferior muscularity baffles. The modality of fixing the k nons is in double points and realizes a superior tight fitting than the usual Bunnell suture. We use this suture in four cases of accidental office and in 11 cases of exquisite rupture, with no reruptures. Based on our own experience, we call for this adaption of Bunnell sutures increases the effectuality of the sutured heftiness and generates a low rate of reruptures.BACKGROUNDThe Achilles tendo n is the largest and the most frequently injured tendon of the human body (1, 2, 3). In cases with accidental section, the only operative treatment is accepted.Treatment protocols for affected roles with acute Achilles tendon rupture include operative and non running(a) management, tho they are ceaselessly being modified (4, 5). The rerupture following acute lesion is the most frequent major complication and it is higher in nonsurgical treatment than in surgical one (6). In surgery the rates is lower, but it is still up to 3% (7, 5). Various surgical methods have been described including open, minim eithery encroaching(a) and transcutaneous repair (8, 9).In inveterate ruptures of Achilles tendon, most authors consider the surgical treatment to be the only satisfactory one (12, 13, 14). In chronic ruptures, we never apply any type of suture but the angmentation only. individually surgeon chooses one surgical techniques because considers it to be associated with a low rate of co mplication. Base on our experience, we consider, in the acute Achilles tendon ruptures, the surgical treatment has some advantages. We present our experience with Bunnell modified suture surgical of Achilles tendon lesions and discus the used techniques in accidental sections and acute ruptures. We believe our modified Bunnell suture to be associated with a lower aim of rerupteres than the original one.MATERIALS AND METHODSThis accept is a retrospective evaluation of uncomplainings with accidental section or acute Achilles tendon ruptures treated by a modified Bunnell suture. Every patient who underwent a modified Bunnell suture of an Achilles between January 2010 and December 2014, was identified and discipline was abstracted from the medical records. All the patients with Achille lesions operated in this period by a modified Bunnell suture were include. It was a number of four patients with section and 11 with acute rupture.In cases with accidental sections the diagnoses was e stablished by clinical examination, and in all cases an immediate surgical repair were performed. It was trio male and one female, between 37 and 42 years old. In all of them an passim modified Bunnell suture was done.In acute ruptures cases the diagnoses was based on story and physical examination. In some cases, an ultrasound or MRI examination was added. All the patients accepted for surgery had to present a palpable drop-off on the tendon, a positive Thompson test and disability to stand on their tiptoes on the injured side. The duration of ruptures from injury to surgery was from a join of days to five weeks. The patients group comprised 11 men and two women ranging in age from 24 to 59 years. The majority of the ruptures were at about 4 to 6 cm proximal to the calcaneal insertion. All the patients were treated by the same technique, a modified Bunnell suture.SURGICAL TECHNIQUESWith the patient under anesthesia, compression bandage control and in prone position, the sur gery started by a posteromedial mark from 4 cm. up to 4 cm. down to the rupture site. The incision is without dissection, shrewdly through the splutter, subcutaneous tissue and fibrous tendon subject. Then, the synovial sheath is carefully dissected and then longitudinally incised on twain side of tendon section or rupture, and protected in order to be easy sutured at the end of tendon repair. The ragged ends of the ruptured tendon are limited excised and with the ankle plantarflexed up to 35 a prepare modified Bunnell suture is done.Fig. 1. Original Bunnell suture (from Coughlin MJ, Schon LC. Disorders of Tendons. In Surgery of the home and Ankle. Eighth edition, Mosby, Inc. 2007.)Fig. 2 Modified centrally running Bunnell suture with two distal knots fixation. This initial variant was not used in cases included in this study.Fig. 3 Modified Bunnell with two laterally sutures. This is our technique which was used in all cases of the study.Fig. 4. Our technique detail.In our technique, instead of one centrally running suture as in original Bunnell (Fig. 1), two laterally sutures on both sides of each stamp, were used (Fig. 3 and Fig. 4). One of the sutures starts from the superior and the other from the inferior tendon soapboxs. Each of the two sutures is passed through the level of section or rupture and then is fixed in the opposite tendon stump. This fixation is by four knots, two in the end of the proximal stump and two in the end of the distal stump in the manner described in fig. 2. In some cases, in particular in cases of tendon sections, the tendon repairing was supplemented with off-and-on(a) circumferential sutures. After tendon repairing, we pay special attention to the synovial sheath suture. It is carefully sutured to strain as long as possible the repaired tendon.Postoperatively, a serial publication of trinity ringlets a used. First is a long cast with the knee in 20 decimal point of flexion and the ankle in 30 degree of plantar fl exion is applied. After three weeks another below-knee with the ankle in 15-20 degree of plantar flexion is applied. The patient is encouraged to move his knee. basketball team weeks after surgery the third below-knee walking cast with the ankle in neutral position or slight flexion is applied. The detain cast is for another two weeks and the progressive weight-bearing is commenced.After cast removal the patient is advised to wear shoe with high heel for another three month and increased activity and physical therapy are begun.RESULTSIn the cases of section the average follow-up was 6 months and ll of them have had the evolutions with no major or minor complications.In the cases of acute ruptures the average follow-up was 12 months. In all cases, no surgery related major complications, such as tendon rerupture or necroses, sural nerve injury, skin necrosis, wound infection, or buddy-buddy infection. As minor complications, at that place were two tendon contracture and one dilet tanteish wound infection which were conservatively treated. In all patients with minor complications, no supplementary surgical treatment was done. None of them had tendon adhesion to the skin and the skin over the tendon was movable. Two patients had cosmetic complaints concerning the scar but without affecting the ankle function.All patients were able to stand on their tiptoes and iodine affected side leg hopping was possible one year postoperatively. diligent range of motion was found to be reduced with limited dorsiflexion in two cases with acute rupture, and the difference was less than 10. At the last follow-up, there had been no cases of rerupture and the subjective satisfaction was excellent or good in all the patients.DISCUSSIONIn accidental section of Achilles tendon, an end-to-end tendon suture is usually done but simple interrupted suture are not sufficient. In these cases, we consider Bunnell suture to be the method of choice. Initially, we modified centrally running Bunnell suture in the manner depicted in fig. 2. This initial variant was not used in cases included in this study. Then, in order to improve the suture strength we used two running suture of the original Bunnell, in the manner depicted in fig. 2. This surgical variant was used in all patients of this study.In acute ruptures of the Achilles tendon the treatment options include nonsurgical and surgical variants. The nonsurgical one avoids the surgical chances but it is associated with a high risk of rerupture (15). Despite the surgical risks, a number of authors consider surgery as a common treatment of Achilles acute ruptures (16, 17, 7).Although, in acute cases, percutaneous procedure increases in popularity, surgery is commonly performed as an open technique (16). The most usual techniques for primary open repair are Bunnel, Kessler and Krackow sutures (6, 19). Although there were reported reruptures after a Bunnell suture, we consider this method and used a modified Bunnell one in the majority of our patients with direct primary sutures. This modified Bunnell is a preference of the main author (IS).Our manner of fixing the knots realizes a superior tight fitting than the usual Bunnell suture. In this variant, instead of two knots both of them placed in the level of section or rupture, there are four knots, two in the end of the proximal stump and two in the end of the distal stump. These four knots are not in the level of section, but two up and two down, proximal to the level of section. Our results suggest this modified Bunnell suture improve the suture strength and is associated with a low rate of reruptures.We consider to be important the justification and dissection of the synovial sheath. At the end of the tendon repairing, a carefully synovial sheath suture has the advantage to create good biological conditions for tendon healing. Based on this special attention to the synovial sheath, in our series none of them had tendon adhesion to the skin.Con clusionsThe results of this study suggest the modified Bunnell suture in our manner has some advantages. In Achilles tendon section or acute ruptures, it is associated with good functional results and a low rate of complications. We consider this type of suture increases the strength of the sutured tendon and generate a low rate of reruptures.
