Bilateral Achilles tendon rupture: a report on two cases

Two cases of traumatic bilateral Achilles tendon rupture are reported. One of the patients was a healthy middle-aged man, who had been an active national-level gymnast 20 years earlier. He had not suffered any complaints of Achilles tendons before. The ruptures occurred when, after a sauna, he showed his guests a vault forwards, which he had been able to perform easily. This time the landing took place on the toes, causing a high peak stretch to the calf muscles and Achilles tendons. The total rupture of both Achilles tendons was treated surgically, with an excellent result 2 days after the trauma. End-to-end suturation and a fascial flap plasty were made on both sides. No macroscopic degeneration could be detected on the rupture sites. He was allowed to walk freely 6 weeks after the surgery. The second case was a 54-year-old woman, who had suffered from Achilles tendinitis and peritendinitis for 2 years. Both tendons had been surgically treated, and severe adhesions and local degenerative changes had been found. The tendon rupture occurred when she injured her left ankle while getting out of the car. Two days later she fell at home, because of the weakness of the left side, and consequently the right Achilles tendon was injured. She was treated conservatively for 10 days, before the surgery was performed. Both tendons were ruptured and an extensive degeneration of the area was observed. The right side suffered from a rerupture, which was again treated surgically. After surgery the recovery was slow, but the final result 3 years later was moderate. Neither of the patients had any systemic diseases.     

Outcome and prognostic factors of achilles rupture repair using a new scoring method

A new clinical scoring system, including subjective assessment of symptoms and evaluation of ankle range of motion and isokinetic measurement of ankle plantar flexion and dorsiflexion strengths, is presented in 101 patients (86 men, 15 women) who had repair of a closed Achilles tendon rupture. Twenty-one patients were competitive athletes and 70 were recreational athletes. Eighty-one percent of the ruptures were related to sports, and 32% occurred while playing volleyball. Twenty-six patients had previous Achilles tendon symptoms. At followup, an average of 3.1 years after repair, the overall result scores were excellent in 34 cases, good in 46, fair in 17, and poor in four. Only age was a predictor of overall results. The isokinetic strength scores were excellent or good in 72 cases, fair in 18, and poor in 11. Presence of systemic diseases, activity level, previous Achilles tendon symptoms, and later return to physical exercise were predictors of strength results. Gender, body weight, height, period between rupture and operation, surgeon, rupture site, operative method, complications, and thickness, width, and area of the Achilles tendon at followup were not related significantly to the outcome.     

Ruptures of the tendo achillis. An objective assessment of surgical and non-surgical treatment

A comparative study is presented of seventy-nine patients with rupture of the tendo achillis, forty-eight of whom were treated surgically and thirty-one, non-surgically. With one exception, all were healthy, athletic individuals. Twenty-two per cent of the patients had an initial misdiagnosis. The patients treated surgically were more satisfied with the results of their treatment. Strength, power, and endurance as measured on the Cybex II dynamometer revealed that the patients treated non-surgically attained only 72 per cent of normal strength and 70 per cent of normal power and endurance as compared with the surgically treated patients. Wound complications occurred in only two patients and no reruptures occurred in the surgically treated group, whereas there were nine rereptures in the group not treated surgically.     

Biochemistry and biomechanics of healing tendon: Part II. Effects of combined laser therapy and electrical stimulation

Twenty-two closed Achilles tendon ruptures caused by sports injuries in 22 patients (average age, 37.6 years) were repaired with Kirschmayer core suture and cross-stitch epitenon suture, and early active ankle motion with weightbearing was implemented after surgery. This study was undertaken to evaluate the effectiveness of the repair technique and rehabilitation protocol by assessing clinical results and magnetic resonance imaging findings. The follow-up period averaged 24.6 months. Twenty of the tendons (91%) healed without rerupture, and two tendons (9%) suffered a partial rerupture at 23 and 56 days, respectively. Active ankle extension reached from the minus range to 0 degree in an average of 9.7 days, and ankle motion recovered to normal in an average of 6.0 weeks. Full weightbearing without heel raising became possible in an average of 16.4 days, and heel raising with both legs became possible in an average of 7.3 weeks. The patients returned to full sports activity in 13.1 weeks. The interval until the area of high-intensity signal at the tendon repair site on T2-weighted magnetic resonance imaging scans became intermediate-intensity signal averaged 6.9 weeks, and the tendon repair site became low-intensity signal in an average of 12.6 weeks, demonstrating excellent tendon healing. Treatment employing Kirschmayer core suture and cross-stitch epitenon suture may help athletes return to sports activity in a shorter period than that allowed by previous methods of repair for Achilles tendon ruptures.     

Current status of treatment of Achilles tendon ruptures. Results of a nationwide survey in Germany]

In a standard questionnaire distributed nationwide, we questioned staff from 1307 clinics (surgical, trauma-surgical, orthopedic), of which 787 clinics (60.2%) answered by letter. In 698 clinics (88.7%), operation is considered the standard therapy. Seventy-five clinics (9.5%) use both conservative and operative therapy (average postoperative rate of complication 3.5%). Only 14 hospitals (1.8%) treat strictly conservatively. The average rate of reruptures is 1.6% in the operated group (77.7% postoperative plaster cast fixation) regardless of postoperative treatment; the conservative group (96.1% functional treatment) showed 2.7% reruptures. Thus, operation is the standard therapy for fresh ruptures of the Achilles tendon in Germany. However, there seems to be a trend towards conservative functional therapy.     

Increasing incidence of Achilles tendon rupture

During the period 1987-91, 153 cases of total Achilles tendon rupture were diagnosed in the city of Malmo (population 230,000). Almost two thirds were caused by sporting activities, notably badminton. Ruptures caused by nonsports injuries were found in older subjects. Compared to the age-specific incidence in 1950-73, a marked increase in both sports and nonsports injuries was found and patients in the latter group were older than in the former period. Patients with Achilles tendon ruptures can be classified into two subgroups with partly different etiologies: young or middle-aged athletes and older non-athletic persons. The increase in the former group is mostly explained by increased participation in recreational sports; the cause of increase in the latter group is unknown.     

Early motion after repair of Achilles tendon ruptures

The purpose of this study was to evaluate the clinical outcome of patients treated with limited immobilization and early motion after repair of acute Achilles tendon ruptures. Thirteen consecutive patients with complete ruptures of the Achilles tendon were identified, repaired, and rehabilitated with early motion starting an average of 10 days after surgery. Active range of motion was begun at an average of 23 days and weightbearing in a walking boot was started at an average of 3.5 weeks after surgery. The average length of follow-up was 27 months. Twelve of 13 patients returned to running activities in an average of 3 months. All 12 patients who participated in lateral motion activities before their injury returned to similar activities in an average of 7 months. The patients rated their overall status at an average of 93% of their preinjury level. Follow-up Cybex testing demonstrated plantarflexion strength averaging 92%, plantarflexion power averaging 88%, and plantarflexion endurance averaging 88% of the nonindexed extremity. Early range of motion after Achilles repair is safe and there is no increased risk of rerupture in compliant patients. The patients achieved good return of plantarflexion strength, power, and endurance.     

Can sonography predict the outcome in patients with achillodynia?

PURPOSE: We evaluated whether the grade assigned to the Achilles tendon's appearance on sonograms can be used to predict the outcome of achillodynia. METHODS: A retrospective evaluation was done of a case series of patients with Achilles tendon pain seen at a sports medicine clinic. The study consisted of chart reviews, telephone follow-up interviews, and grading of ultrasound images of the tendon obtained during the initial visit. The grading scheme was as follows: grade 1, normal tendon; grade 2, enlarged tendon; and grade 3, tendon containing a hypoechoic area, regardless of size. The time needed to recover from symptoms was compared between grades using survival analysis. RESULTS: The group consisted of 33 patients, with a mean age of 35.8 years and a mean follow-up time of 24.3 months. There was a statistically significant difference in the time to full recovery between grades (p = 0.02). Patients with grade 1 tendons had a prompter resolution of symptoms than did patients with grade 2 or 3 tendons. CONCLUSIONS: This retrospective study of the outcome of achillodynia demonstrates the possible use of tendon sonography as a prognostic tool to supplement physical examination.     

Valproic acid treatment of epilepsy in autistic twins

Ultrasound-guided percutaneous core biopsy technique was studied in 15 consecutive patients with chronic Achilles tendon disorder defined as persisting local pain during daily activities, localized pain and swelling on palpation 2-5 cm proximal to the calcaneal insertion. Ultrasound verified widening of the tendon and low echogenous areas at the site of pain. Percutaneous biopsies were taken from both the low echogenous areas and the normoechogenic tendon tissue. Of 104 core biopsies 99 were representative. Open biopsies were taken from the macroscopically injured and normal tendon for comparison. Core and open biopsies of the low echogenous and macroscopically injured tendon showed similar histopathology. In 10 patients the core biopsy was performed under local anesthesia with limited subjective symptoms. Five of these patients were operated 18-41 days later. No adverse effect was found referring to the biopsy taken a few weeks prior to surgery. No complications occurred. We conclude that the percutaneous core biopsy, guided by ultrasound and performed under local anesthesia, can be used under clinical and experimental in vivo studies for improving knowledge on pathoanatomy and healing processes of the Achilles tendon.     

Achilles tendon rupture. Surgical or non-surgical treatment

Opinions differ about the proper treatment of Achilles tendon rupture. 38 patients with acute total rupture of the Achilles tendon were included in a comparative study of operative as against non-operative treatment. 21 of the patients were treated operatively and 17 non-operatively. The follow-up time was 6-53 months. Three of the non-operated patients but none of the operated group experienced major complications. Ten of the non-operated patients and 14 of the non-operated group experienced minor complications. In the non-operated patients the plantar-flexion range was significantly reduced in the injured foot compared with the other foot (p = 0.03). Because of more re-ruptures and reduced muscle strength in the non-operative group, operative treatment is recommended for active persons. Non-operative treatment may be considered for older people.     

The treatment of prolactinomas during pregnancy and the lactation period

Thanks to its good long-term results, surgery is the method of choice to treat subcutaneous ruptures of the Achilles tendon. Reconstructed tendons present typical morphological and functional US patterns which depend partly on the kind of surgical reconstruction and partly on the time passed since surgery. The authors report the results of the clinical and US follow-up of a series of 62 surgical patients treated in 7 years for the subcutaneous rupture of the Achilles tendon. The patients were 55 men and 7 women, whose mean age was 36 years (range: 25-65 years). The left-hand side was affected in 38 patients and the right-hand side in 24 patients. All patients were operated on using an end-to-end suture and reinforcement plastic surgery pulling down a gastrocnemius tendon flap. To homogenize the results, all the US exams were performed by the same operator, in the presence of the orthopedic specialist and under the same conditions: both the involved and the contralateral Achilles tendons were studied, longitudinal and transverse scans were performed with the foot in max. plantar and dorsal flexion and, whenever possible, dynamic scans were also performed making the sural triceps contract against resistance. The following parameters were studied clinically: pain (which was absent in 39 patients, occasional in 11, after stress in 9 and on walking in 3 patients), skin scar trophism (which was eutrophic in 53.23% of patients, keloid in 27.42% and hypertrophic in 19.35% of patients), ankle joint excursion (plantar flexion was impaired in 32.3% and dorsal flexion in 36% of patients), walking on tiptoe (in all, 22.6% of patients complained of difficulties walking on tiptoe) and, finally, work activity resumption (which all patients achieved). US depicted the surgical tendons as much bigger than the contralateral ones (3-4 times on the average), which increase in volume lasted throughout the follow-up. In 75% of patients the echo structure of the surgical tendons was inhomogeneous, with scattered hypoechoic and hyperechoic areas. In the extant 25% of patients, nearly all of them followed-up for over 6 years, US depicted a clear-cut hyperechoic area whose size and echo structure were similar to the healthy tendons'. Our results strongly suggest that tenorrhaphy and flap plastic surgery be used to repair subcutaneous ruptures of the Achilles tendon. US proved to be the most reliable and feasible method also in the follow-up. The US images of the patients submitted to surgery more than 6 years earlier revealed fibrillate reorganization patterns and tendon restructuring. These processes involve both ends of the sutured tendon and not the reinforcement flap, which further confirms the exclusively mechanical, and not biological, function of the latter.     

Conservative functional therapy of closed rupture of the Achilles tendon. Treatment approach and analysis of results

In a prospective study in the period from May 1989 to April 1994, 161 patients at the Unfallchirurgische Klinik in Braunschweig were treated for rupture of the Achilles tendon using a conservative functional method. A follow-up examination was carried out on 132 patients (81%) after an average of 12.6 months. Conservative therapy was indicated if dynamic ultrasonography showed sufficient adaptation of the rupture. Continuous retention of the adapted tendon fragments was guaranteed by means of special footwear that raises the back of the foot (Variostabil). The average age of the patients was 39.5 years. In 97 cases (73.5%) the injury was caused by sports. In 68 ruptures the dehiscence was compensated in plantar flexion. In 48 cases the dehiscence was 1-5 mm, and in 16 cases it was between 6 and 10 mm. The average period of hospitalization was 4.8 days (1/19). The period of inability to work was an average of 4 weeks (27.4 days (0/98)). The rupture healed on an average of 9.5 weeks (5.9/23). Complications included seven cases of re-rupture (5.3%), and, in the course of treatment, four patients (3%) suffered profound leg vein thrombosis that in one case developed into postthrombotic syndrome. In two cases there was tendovaginitis of the Achilles tendon. Early functional conservative therapy using the VARIO-STABIL shoe is a suitable method for treating a newly ruptured Achilles tendon. When there is a precise indication, the method is equally as good as operative therapy and because of the low complication rate, it is even preferable.     

Gait analysis and muscle strength in children with surgically treated clubfeet

Twenty-three children who had unilateral surgery for idiopathic clubfeet underwent gait analysis and isokinetic muscle-strength testing at an average of 10 years after surgical release. Ankle sagittal-plane kinematics were disturbed in 20 clubfeet. Fifteen children had an internal foot-progression angle. Genu valgum and knee hyperextension were common. Plantarflexion power was decreased by 23% on the side of surgery (p = 0.00005). Quadriceps weakness (defined as a decrease in strength >10% of the nonoperated-on limb's strength) was seen in nine of 22 operated-on limbs and hamstring weakness in eight of 22. Gastrocsoleus weakness exceeded 10% in 16 of 21 clubfeet. Average weakness of the gastrocsoleus was 27% (p < 0.05). Ten-year analysis of children treated with clubfoot releases revealed disturbances in ankle motion and strength. Loss of plantarflexion power and gastrocsoleus strength can be predicted by Achilles tendon lengthening. Knee kinematic abnormalities and weakness also were seen. These abnormalities produce functional difficulties in gait and may lead to degenerative changes later.     

Etiology, histopathology, and outcome of surgery in achillodynia

Fifty-eight patients suffering from achillodynia for a median of 12 months (range, 4-240 months) were analyzed using history, clinical findings, ultrasound findings, histopathology, and surgical outcome. Surgical criteria were daily pain or inability to perform sports activity and failure of nonoperative treatment. There were 34 men and 24 women, 31% (18 of 58 patients) of whom had no direct association with sports or vigorous physical activity. Ultrasonography was performed in all cases and showed low echogenous areas (N = 48), increased tendon diameter (N = 40), and/or peritendinous fluid (N = 11). Histopathological evaluation of tendon biopsies, obtained from regions showing pathology at surgery (N = 35), revealed altered fiber structure and arrangement, focal variations in cellularity, extracellular glycosaminoglycans, neovascularization, and/or hyalinization. In no case was inflammatory cell infiltration observed. At a median clinical follow-up of 25 months after surgery, symptoms were decreased in 86% of patients, and 76% had reached a higher activity level compared with the level before surgery. Complications occurred in 13% of operations. In conclusion, achillodynia is not always associated with excessive physical activity. Macroscopic pathologic tendons showed marked histopathologic changes, correlating well with ultrasound findings. Surgical treatment was beneficial in most cases, despite a relatively high complication rate. The etiology and reason for the lack of healing response to rest and nonoperative treatment are unclear.     

Locations of crossover breakpoints within the CMT 1 A-REP repeat in patients with hereditary neuropathy with liability to pressure palsy--detection by recombinant chromosome-specific polymerase chain reaction

The "short Achilles tendon" syndrome, characterised by limited dorsiflexion of the tibiotarsal joint, is not well-known but could be a disposing factor for trophic disorders and plantar ulcer related to hypersupport in the diabetic subject. We report two cases of multicomplicated diabetic patients treated during several months for plantar ulcer superinfected with underlying osteoarthrits, whose course became rapidly favourable after tenotomy of the Achilles tendon. This simple surgical act can be performed in ambulatory conditions under local anaesthesia. Functional disability is negligible. The benefit of this treatment as part of the curative or preventive therapeutic arsenal for care of the diabetic foot remains to be evaluated.     

Apoptosis of tubular epithelial cells in familial juvenile gouty nephropathy

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.     

Surgical repair of Achilles tendon rupture. Comparison of surgical with conservative treatment

Achilles tendon suture combined with a triceps surae tendon tip-over graft was performed in 314 patients with acute rupture of the Achilles tendon between 1980 and 1991. Analysis of these cases showed a low tissue complication rate compared with that reported in the literature. An average of 8.1 years after repair, 223 patients were examined using Holz's scale of clinical assessment after Achilles tendon repair. The results were 'good' in 87.4%, 'fair' in 11.2% and 'poor' in 1.4%. The re-rupture rate was very low (0.4%). These results are better than the re-rupture rate after surgical repair with solely end-to-end suture or after conservative immobilizing or conservative functional treatment. In conclusion, these data show that the fascial reinforcement is a valuable complement to the tendon suture.     

Tendon transfer for equinovarus deformed foot caused by cerebrovascular disease

Surgical correction was performed on 125 patients who had equinovarus deformity caused by a cerebrovascular accident and who needed an ankle foot orthosis for walking. The operative procedures involved anterior transfer of the long toe flexors (flexor hallux longus and flexor digitorum longus; long toe flexor group) or lateral transfer of the anterior tibial tendon (anterior tibial tendon group), combined with lengthening of the Achilles tendon. On evaluation more than 2 years after surgery, 83 of 110 patients of the long toe flexor group and eight of 15 patients of the anterior tibial tendon group were able to walk without a brace. Five patients of the anterior tibial tendon group who had shown strong contraction of the anterior tibial muscle during the swing phase before surgery, needed a brace because of a drop foot after surgery. Thus, lateral transfer of the anterior tibial tendon was abandoned in 1984. Recurrence of varus deformity was seen in approximately 15% of the patients in both groups. Anterior transfer of the long toe flexors, using them as dorsiflexor tendons or for tenodesis, seemed to produce better results.     

Elbow arthroscopy in a mostly athletic population

The effectiveness of elbow arthroscopy was assessed in 35 consecutive patients (primarily weight lifters and baseball players) treated by one surgeon. The most commonly treated lesions were loose bodies and impinging spurs. Most elbow problems resulted from repetitive or acute athletic trauma. Repetitive stress injuries usually involved the athlete's dominant arm (91%). A standardized rating system demonstrated significant improvement at 24 months' average follow-up. Flexion and extension improved an average of 9 and 6 degrees, respectively. Elbow arthroscopy appears to be a safe and effective treatment for athletes, allowing most a full return to participation in sports.     

One hundred years of orthopedics in the Netherlands. X. Sports injuries

Sports injuries result from frequently repeated similar movements performed with submaximal force. In practice the term is also used, incorrectly, for many other injuries sustained during, or even outside, the practising of sports. Running may lead to injuries of muscles (rupture, chronic compartment syndrome), of tendons (peritendinitis, tendinosis, partial rupture, insertion tendinitis), of bone (stress fracture) and of cartilage (athrosis). Jumping mostly puts the ankle at risk, especially of development of an anterior or posterior impingement syndrome. Throwing puts much strain on the shoulder muscles; possible problems are microruptures in the rotator cuff, avulsion of the glenoid rim, chronic tendinitis of the biceps tendon and entrapment of the suprascapular nerve. The main element of the treatment is rest. If symptoms persist, surgery may be considered. Previous diagnostic imaging may then be of value.
