Repair of flexor carpi radialis tendon laceration at the wrist in a professional ice hockey player

The flexor carpi radialis is a wrist flexor and radial deviator with half the relative strength of flexor carpi ulnaris. In the majority of patients, the flexor carpi radialis tendon is expendable and is routinely used for various reconstructive procedures about the hand and wrist. Isolated flexor carpi radialis lacerations at the wrist are rare. Flexor carpi radialis tendon ruptures, which have been reported in association with distal radius fractures, longstanding osteoarthritis, and percutaneous treatment of scaphoid fractures, are usually treated non-operatively. We report a case of a traumatic laceration of the flexor carpi radialis tendon at the wrist in a professional ice hockey player. Surgical repair and rehabilitation using established principles for intrasynovial flexor tendon repair allowed return to sport at the professional level in 2 months.Tension-free core suture repair was performed with a modified-Kessler, 4-strand repair using a double-stranded 4-0 Supramid suture. A running epitendinous suture was then placed around the circumference of the tendon with 6-0 Prolene. Immobilization of the wrist in 20° of flexion was maintained for 2 weeks. Full active and passive digital motion was allowed immediately postoperatively and continued throughout the rehabilitation. Therapy was initiated at 2 weeks postoperatively with full passive wrist flexion and passive wrist extension to a dorsal block of 20°. At 4 weeks postoperatively, a dorsal splint was fabricated to keep the wrist in neutral. At this time, active extension to a dorsal block of zero and full passive flexion was allowed. Active wrist flexion without resistance was begun at 6 weeks, and full strengthening was allowed at 8 weeks postoperatively. The patient returned to sport at the professional level shortly thereafter. At latest follow-up, the patient has been able to fully participate in professional ice hockey without pain or functional limitation.     

Augmented Repair of Acute Total Achilles Tendon Rupture With Peroneus Brevis Tendon Transfer Using Oblique Transosseous Calcaneal Tunnel: A Prospective Case Series

Acute Achilles tendon rupture is one of the most common tendon injuries. This prospective study aimed to evaluate the functional outcomes of augmented repair of acute Achilles tendon rupture with peroneus brevis tendon transfer and fixation to an oblique calcaneal transosseous tunnel. Functional evaluation was performed using the American Orthopaedic Foot & Ankle Society (AOFAS) score and Achilles Tendon Total Rupture Score (ATRS). Postoperative complications were recorded. This study included 33 males and 9 females, with a mean age of 26.1 ± 4.2 years. The Achilles tendon ruptures were right in 24 patients and left in 18 patients. The cause of rupture was sports injuries in all patients. The mean distance from the calcaneal insertion to the tear site was 4.4 ± 1.3 cm. The mean time from injury to surgery was 2.4 ± 1.6 days. The mean follow-up time was 40.3 ± 4.9 months. The mean AOFAS and ATRS scores were 99.3 ± 1.2 and 95.9 ± 1.9, respectively, at 12 months of follow-up. The mean time to return to work was 12.1 ± 1.2 weeks. The mean time to return to light sports activities was 16.1 ± 1.8 weeks postoperatively. None of the patients developed re-rupture. Augmented repair of acute Achilles tendon ruptures with peroneus brevis tendon transfer is a robust repair with excellent functional outcomes and early weight-bearing and return to sports activities.     

Concomitant Talar Neck Fracture and Achilles Tendon Rupture

A 56-year-old man fell down 1 m from a ladder and sustained a forced dorsiflexion injury to his right ankle when his foot contacted a lower rung, which resulted in the rare combination of a Hawkins II fracture of the neck of the talus and a concomitant rupture of the Achilles tendon. Clinical examination and diagnostic imaging confirmed the injuries, and surgical fixation of the fracture and repair of the Achilles tendon were achieved by means of a posterior approach. Healing proceeded unremarkably, and, at 18 months postoperatively, the patient had regained full function despite a 5 degrees limitation of subtalar joint range of motion.     

Outcome of achilles tendon ruptures treated by a limited open technique

BACKGROUND: The optimal surgical management of Achilles tendon ruptures remains a topic of active debate. Recently, many authors have preferred the limited open method because it afforded sufficient visualization to ensure anatomic apposition of disrupted tendon fibers, minimized local blood supply disturbances, guaranteed free tendon movement, and produced excellent cosmesis. We report our initial experience with this technique and review the literature. MATERIALS AND METHODS: The outcomes of 30 consecutive patients that underwent limited open repair for Achilles tendon rupture using Achillon (Newdeal SA, Lyon, France) from June 2003 to May 2006 were retrospectively reviewed. There were 20 men and 10 women, of average age 38.6 years, and the average followup period was 18.5 months. Twenty of the injuries were sports-related, eight were caused by a fall, and two by a laceration. The clinical results were assessed using patient satisfaction, the ankle-hindfoot scale of the American Orthopaedic Foot and Ankle Society (AOFAS), and the occurrence of complications. RESULTS: At last followup, sixteen patients were very satisfied, 11 were satisfied, and the remaining three were dissatisfied. Mean patient AOFAS score was 93.0 points. Surgical complications noted were re-rupture in two cases, deep infection in one, and sural nerve injury in one. All patients except the three patients with a re-rupture or infection, returned to work 2 months postoperatively and resumed light exercise at 3 months, and previous sporting activities by 6 months. CONCLUSION: The described limited open repair technique for Achilles tendon ruptures provided excellent cosmetic results, satisfactory functional results, and a high level of patient satisfaction.     

A Combined Repair Technique for Early Neglected Achilles Tendon Ruptures

Abstract Objective: This study presents the long-term results of a combined technique, using both Duthie's biological repair and a plantaris tendon transfer for the reconstruction of early neglected tendo Achilles ruptures. Materials and Method: Between January 2000 and November 2004, nine patients with an early neglected Achilles tendon rupture (≥ 4 and ≤ 12 weeks from injury), underwent surgical reconstruction. Eight patients were male and one female, their age was average 41 years and the median follow-up period was 3.66 years. The average clinical defect of the Achilles tendon was 4.33 cm. Results: All patients were examined by the clinical ankle scoring system of Leppilahti et al. (Clin Orthop 346:152–161, 1998). Six patients presented excellent results and three patients had good results. All patients had equal plantarflexion and dorsiflexion with the healthy side and all of the study's patients returned to work 3 months postoperatively. An average muscle atrophy of 0.83 cm was documented compared with the uninjured side. Only four of nine patients (44.44%) had a normal one-legged jump. There were no complications postoperatively and no re-ruptures of the Achilles tendons. Conclusion: This combined method appears to be safe and effective, with a low risk for complications, allowing us to obtain excellent results for the majority of our patients.     

Tendon Disorders of the Foot and Ankle

Attritional and traumatic injuries to the tendons around the foot and ankle are not uncommon. Treatment of overuse-type injuries (tendinitis) remains straightforward. However, surgical treatment of peroneal subluxation, Achilles tendon ruptures, and posterior tibial tendon insufficiency remains somewhat controversial. Generally speaking, soft-tissue reconstruction of the superior peroneal retinaculum is superior to bony procedures for peroneal dislocation. Open repair of a torn Achilles tendon is more predictable than closed treatment. Good clinical judgment is needed in determining the best treatment for posterior tibial tendon problems. The painful os peroneum syndrome is a newly described spectrum of posttraumatic conditions that may be the cause of lateral foot pain, which is frequently difficult to identify.     

Häufig und selten kombiniert ergibt sehr selten Kombinierte Talushalsfraktur und Achillessehnenruptur

BackgroundIn both injuries, an isolated Achilles tendon rupture and a talar neck fracture, the mechanism of injury is supposed to be a forced dorsiflexion of the foot. Yet the combination of these injuries is uncommon. It remains uncertain whether further efforts to diagnose a taler neck fracture in any dorsiflexion foot traumas are made. Nevertheless, the knowledge of the presence of a combination of these injuries could be helpful in the decision making between an operative and a conservative therapy option.Material and MethodsA 44-year old mountain biker suffered a forced dorsiflexion of his left foot after landing a jump. In the clinical examination and radiography a Achilles tendon rupture and a talar neck fracture Hawkins I were diagnosed. Due to the combination of injuries, we decided an operative therapy with screw osteosynthesis and direct tendon repair.ResultThree months post-surgical fixation of the talar neck fracture and repair of the Achilles tendon rupture, the patient had regained full weight bearing function despite a slight reduction of the ROM in dorsiflexion/plantarflexion 10/0/20°.ConclusionConsidering the good outcome in this case we highly recommend an operative procedure. Especially due to the high risk for a secondary dislocation of the talus fracture in case of insufficient immobilization.     

Achilles allograft reconstruction of a chronic patellar tendon rupture

Chronic ruptures of the patellar tendon are uncommon injuries. They are technically difficult to repair because of scar formation, poor quality of the remaining tendon, and quadriceps muscle atrophy and contracture. We report the reconstruction of a chronic patellar tendon rupture with an interesting complication, a tibial stress fracture. The reconstruction was performed 3 months after the injury using an Achilles tendon-bone allograft and reinforcing suprapatellar wire. At 2 weeks postoperatively, the patient had attained full extension and 90 degrees of flexion. Ten months after the index procedure, the patient had range of motion 0 degrees to 120 degrees and was diagnosed with a healing tibial stress fracture. At 17 months postoperatively, the patient had attained full extension, 120 degrees of flexion, and 85% quadriceps strength. The preoperative goals of attaining full range of motion, improving quadriceps strength, obtaining anatomic patellar alignment, and restoring function were obtained despite the complication of a tibial stress fracture. Although this reconstructive procedure is technically demanding, with potential complications, the functional results obtained can be excellent.Arthroscopy 1998 Apr;14(3):340-4     

Chronic rupture of a patellar tendon: A technique for reconstruction with achilles allograft

Chronic ruptures of the patellar tendon fortunately are an uncommon event. These ruptures are often difficult to repair because they are generally accompanied by quadriceps muscle contracture and a great deal of scar tissue formation. We report the case of a repair of a chronic patellar tendon rupture. The patient's right patellar tendon was reconstructed approximately 10 months after the injury using quadricepsplasty and an Achilles tendon allograft with a suprapatellar wire for tension release. Four weeks postoperatively, he had attained 60° of flexion and full active extension. At 8 weeks, the suprapatellar wire was removed allowing the distribution of stresses on the reconstructed patellar tendon. At 6 months, the patient had 130° of flexion and full extension, but showed a persistent 40% deficit in right quad strength. The technique accomplished the preoperative goals of restoring quadriceps function, restoring the anatomic position of the patella, and allowing early mobilization after surgery. Although the use of a suprapatellar wire to reduce tension on the reconstructed tendon required a second operation for removal, it allowed early mobilization and better healing of the repair.     

A Minimally Invasive “Overwrapping” Technique for Repairing Neglected Ruptures of the Achilles Tendon

About 10% to 25% of acute ruptures of the Achilles tendon go undiagnosed for some time beyond what would be optimal for repair and a return to optimal function. Managing these chronic or neglected ruptures is a surgical challenge, because the tendon ends retract and atrophy and could develop a short, fibrous distal stump. In the present report, a patient with a ruptured right Achilles tendon, neglected for approximately 10 years, is described. The chronically injured tendon was successfully treated by overwrapping the interposed scar at the rupture site. This minimally invasive technique restored tension to the tendon, a prerequisite for which was the presence of functional triceps surae, confirmed by identification of gross contraction of the muscle during tiptoeing. The procedure is contraindicated when the scar tissue is not intact and does not have sufficient laxity to allow adequate dorsiflexion of the ankle after overwrapping the tendon or when the triceps surae are nonfunctional.     

Repair of Achilles Tendon Rupture Using Autologous Semitendinosus Graft in a Kidney Transplant Recipient

Insertional Achilles tendon injuries can be difficult to treat when minimal tendon tissue remains for anastomosis. Moreover, in the chronic case with tendon shortening, operative repair can be more difficult than acute rupture. It is particularly desirable to reinforce the tendons, in addition to performing primary repair, in patients with renal or systemic diseases because of the accelerated collagen degeneration. Many techniques have been described for the surgical management of Achilles tendon rupture; however, none has shown clear superiority. We report the case of a 50-year-old renal transplant patient with a spontaneous distal Achilles tendon injury that we repaired using the pull-out technique reinforced with an autologous semitendinosus graft. At 2 years postoperatively, the ankle-hindfoot scale score was 92 points, and the postoperative course was without complication. We believe that the free hamstring tendon autograft is advantageous for this repair, because it is easy to handle, has limited donor site morbidity, and preserves the structures around the ankle.     

Percutaneous suturing of the ruptured Achilles tendon with endoscopic control

Introduction  A prospective study of modified percutaneous Achilles tendon repair performed between 1999 and 2005 under local infiltration anesthesia is presented; the study evaluated the results of percutaneous repair technique by visualization of the synovia under endoscopic control, followed by early functional postoperative treatment for surgical intervention of acute Achilles tendon ruptures. Patients  Sixty-two patients (58 males, 4 females, mean age 32) were treated by percutaneous suturing with modified Bunnel technique under endoscopic control within 10 days after acute total rupture. Physiotherapy was initiated immediately after the operation and patients were encouraged to weight-bearing ambulation with a walking brace-moon boot as tolerated. Full weight-bearing was allowed minimum after 3 weeks postoperatively without brace. Results  The procedure was tolerated in all patients. There were no significant ROM limitation was observed. Two patients experienced transient hypoesthesia in the region of sural nerve that spontaneously resolved in 6 months. Fifty-nine patients (95%) including professional athletes returned to their previous sportive activities, while 18 of them (29%) had some minor complaints. The interval from injury to return to regular work and rehabilitation training was 11.7 weeks (10–13 weeks). At the latest follow-up (mean: 46 months; range: 12–78 months), all the patients had satisfactory results with a mean American Orthopedic Foot and Ankle Society’s ankle-hindfoot score of 94.6. No re-ruptures, deep venous thrombosis or wound problems occurred. Conclusion  The proposed method offers a reasonable treatment option for acute total Achilles tendon rupture with a low number of complications. The rerupture rate and return to preinjury activities are comparable to open and percutaneous without endoscopic control procedures.     

Management of chronic ruptures of the Achilles tendon

Chronic ruptures of Achilles tendons are those that present four to six weeks after the original injury. They have become more common as acute Achilles tendon injuries have become more frequent, and they are associated with considerable functional morbidity. Most surgeons agree that chronic ruptures should be managed operatively. Diagnosis is based predominantly on history and clinical examination. Real-time, high-resolution ultrasound and magnetic resonance imaging are helpful in preoperative planning or as a diagnostic aid. Local tissue, local tendons, and allografts can be used to reconstruct the tendon, and end-to-end repair is possible if the gap is <2.5 cm. Compared with acute injuries, chronic injuries are associated with a higher rate of postoperative infection and more prolonged recovery.     

Repair of Lacerated Anterior Tibial Tendon with Acellular Tissue Graft Augmentation

In the present case report, we describe the surgical repair of a complete laceration of the anterior tibial tendon using acellular human dermal tissue matrix. A 17-year-old, elite league hockey player was injured in the locker room when a teammate still clad in ice skates stepped on his bare left foot. After evaluation at a local emergency department, the patient presented to our office the next day for additional evaluation. It was determined that surgery would be performed using acellular tissue graft augmentation, followed by physical therapy. Within 7 weeks of the injury, the athlete returned to his original level of activity. At 3 years of follow-up, he was playing Division 1 hockey at the university level. We believe that augmentation of the tendon repair with the grafting material enhanced the tendon tensile strength and promoted ingrowth through vascular channels. This, combined with the patient’s dedication to physical therapy, led to excellent recovery in less time than anticipated.     

Bilateral achilles tendon ruptures in a patient with ochronosis: a case report

We report the case of a 67-year-old man with ochronosis who had bilateral Achilles tendon ruptures. We reconstructed the Achilles tendon using pull-out wiring for the right side and an anchoring system for the left side, and reinforced the repair site using the peroneus brevis tendon for both sides. He could walk without a cane at 3 months postoperatively. Tendon ruptures in patients with ochronosis should be treated as pathologic ruptures because histologic examination reveals that both ends of the ruptured tendon and the insertion site at the calcaneus have extensive black pigment depositions where homogentisic acid and its metabolites have accumulated, and there are no normal collagen bundles present. Even if an Achilles tendon rupture is clinically diagnosed as an acute injury, the ruptured Achilles tendon should be primarily repaired and reinforced with autologous tissue because there are a few viable cells at the ruptured site, and because the tendon ruptures mainly at the insertion site of the calcaneus. Although this is a preliminary report, the short-term result is good and the reconstructed sites have showed no rerupture.     

Anterior Rectus Sheath Autograft in WRAP-Augmentation of Achilles Tendon Rupture

Achilles tendon ruptures can be counted as the most common traumatic ankle injuries. As such, there is a comparatively large set of treatment options including surgical and nonsurgical approaches. The purpose of this case report is to demonstrate a new technique for a specific subgroup of Achilles tendon ruptures that present with a large tendinous gap. We used a 2-step procedure designed to grant additional stability through an autograft from the anterior rectus sheath of the patient. Two patients were treated after suffering traumatic Achilles tendon ruptures on the left side with a gap of >3.5 cm and a high demand in daily activities. The reconstruction was performed using an upper quadrant recuts sheath as a WRAP-augmentation. After securing the transplant tissue, the abdominal wall was reconstructed using a Vicryl™-Prolene™ mesh (VYPRO®, Johnson & Johnson Medical GmbH, Ethicon Deutschland, Norderstedt, Germany). After, a standard approach to the Achilles tendon was performed with a Kirchmayr-Kessler suture. The end result was then stabilized with a rectus sheath WRAP over a length of 14 to 15 cm. On the cases reported here, multiple clinical follow-ups were performed over a 5-year period. We can report highly satisfying results, with a return to sports activity after 6 months and no complications. As such we believe the rectus sheath autograft an effective solution for Achilles tendon ruptures with large gaps in healthy patients that demonstrate a high demand in daily activities.

Nonsurgical treatment and early return to activity leads to improved Achilles tendon fatigue mechanics and functional outcomes during early healing in an animal model

Achilles tendon ruptures are common and devastating injuries; however, an optimized treatment and rehabilitation protocol has yet to be defined. Therefore, the objective of this study was to investigate the effects of surgical repair and return to activity on joint function and Achilles tendon properties after 3 weeks of healing. Sprague–Dawley rats (N = 100) received unilateral blunt transection of their Achilles tendon. Animals were then randomized into repaired or non‐repaired treatments, and further randomized into groups that returned to activity after 1 week (RTA1) or after 3 weeks (RTA3) of limb casting in plantarflexion. Limb function, passive joint mechanics, and tendon properties (mechanical, organizational using high frequency ultrasound, histological, and compositional) were evaluated. Results showed that both treatment and return to activity collectively affected limb function, passive joint mechanics, and tendon properties. Functionally, RTA1 animals had increased dorsiflexion ROM and weight bearing of the injured limb compared to RTA3 animals 3‐weeks post‐injury. Such functional improvements in RTA1 tendons were evidenced in their mechanical fatigue properties and increased cross sectional area compared to RTA3 tendons. When RTA1 was coupled with nonsurgical treatment, superior fatigue properties were achieved compared to repaired tendons. No differences in cell shape, cellularity, GAG, collagen type I, or TGF‐β staining were identified between groups, but collagen type III was elevated in RTA3 repaired tendons. The larger tissue area and increased fatigue resistance created in RTA1 tendons may prove critical for optimized outcomes in early Achilles tendon healing following complete rupture. © 2016 Orthopaedic Research Society.

Evolution of the Achilles tendon: The athlete's Achilles heel?

The Achilles tendon is believed to have first developed two million years ago enabling humans to run twice as fast. However if the Achilles tendon is so important in terms of evolution, then why is this tendon so prone to injury – especially for those more active like athletes. The Achilles tendon had an integral role in evolving apes from a herbivorous diet to early humans who started hunting for food over longer distances, resulting in bipedal locomotion. Evolutionary advantages of the Achilles tendon includes it being the strongest tendon in the body, having an energy-saving mechanism for fast locomotion, allows humans to jump and run, and additionally is a spring and shock absorber during gait. Considering these benefits it is therefore not surprising that studies have shown athletes have thicker Achilles tendons than subjects who are less active. However, contradictory to these findings that show the importance of the Achilles tendon for athletes, it is well known that obtaining an Achilles tendon injury for an athlete can be career-altering. A disadvantage of the Achilles tendon is that the aetiology of its pathology is complicated. Achilles tendon ruptures are believed to be caused by overloading the tensed tendon, like during sports. However studies have also shown athlete Achilles tendon ruptures to have degenerative changes in the tendon. Other flaws of the Achilles tendon are its non-uniform vascularity and incomplete repair system which may suggest the Achilles tendon is on the edge of evolution. Research has shown that there is a genetic influence on the predisposition a person has towards Achilles tendon injuries. So if this tendon is here to stay in our anatomy, and it probably is due to the slow rate of evolution in humans, research in genetic modification could be used to decrease athletes’ predisposition to Achilles tendinopathy.     

Percutaneous repair of acute ruptures of the tendo Achillis

Minimally invasive repair of acute traumatic ruptures of the tendo Achillis may produce lower complications compared to open repair. Twenty-three active patients underwent percutaneous repair of an acute rupture of the tendo Achillis. Post-operatively, the ATRS score was administered to assess the functional status. The maximum calf circumference, isometric plantar flexion strength of the gastrocsoleus muscle complex, ankle dorsiflexion, and return to sport activity were assessed in all patients at an average post-operative follow-up of 25.7 months. At the last follow-up, the mean Achilles tendon total rupture score (ATRS) score was 84 (range: 53–99). Ankle dorsiflexion and maximum calf circumference on the operated limb were not significantly different compared to the uninjured side. The isometric strength on the operated limb was significantly lower (P = 0.04) compared to the contralateral side. Of the 21 (90%) patients participating in sports activities, 16 (80%) had returned to their pre-operative sport, 2 changed to lower activity, and 1 increased his performance. This percutaneous technique provides satisfactory outcome in terms of strength and return to pre-operative level of sport activity.
