Achilles and peroneal tendon injuries in the athlete. An expert's perspective

Peroneal tendonopathy or injuries are not common but may be troubling to the sports enthusiast. Prompt diagnosis and treatment usually result in complete recovery with conservative measures. Biodynamic orthosis with deep heel cups and a long lateral flange extension often are required for return to activity. MR imaging is helpful in difficult, persistent cases to check for ruptures. Surgery is not commonly performed but if required is usually successful in correcting the pathology. Alternative medicine may improve treatment outcomes. Biomechanical functional analysis and attention to training errors is essential in any lower extremity injury or pathology.     

Blood supply of the Achilles tendon

The Escherichia coli low molecular mass penicillin-binding proteins are enzymes associated with the periplasmic face of the inner membrane. This mini review discusses the membrane anchoring of these enzymes and their possible participation in a putative membrane bound protein complex involved in the regulation of peptidoglycan biosynthesis. The identification of such a complex may lead to the identification of new sites of action for antibacterial compounds.     

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.     

Fracture of the ossified Achilles tendon

OBJECTIVE: To analyse the relation between induced abortion and risk of subsequent miscarriage. DESIGN: Case-control study conducted between February 1990 and May 1995. PARTICIPANTS: Case group included 782 women (median age 32 years, range 14-46) admitted for spontaneous abortion (within the 12th week of gestation) to a network of obstetric departments in the greater Milan area. The control group was recruited among women who gave birth at term (> 37 weeks of gestation) to healthy infants on randomly selected days at the hospitals where cases had been identified. A total of 1543 controls (median age 30 years, range 14-45) were interviewed. RESULTS: A total of 102 cases (13%) and 181 controls (12%) reported one or more induced abortions. No clear relation emerged between miscarriage and induced abortions. In comparison with women reporting no induced abortion the odds ratio (OR) for miscarriage were 1.1 (95% CI 0.8-1.4) in women reporting one induced abortion and 0.9 (95% CI 0.4-1.8) in women reporting two or more. Likewise, there was no association between time since last and age at first induced abortion and risk of miscarriage. CONCLUSIONS: This study did not find any strong association between induced and spontaneous abortion.     

Ultrasonography of the Achilles tendon in hypercholesterolemia

The classical treatment of uretero-ileal anastomotic strictures after Bricker uretero-ileostomy is open surgical revision. Recent progress in endourology has provided a number of alternatives. The success rate of these endoscopic techniques is less than the success rate of the open surgical revision.     

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.     

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.     

Diseases of the Achilles tendon in dogs and cats

Dogs and cats rarely have problems with the Achilles tendon and if so, it usually results from a direct trauma. Prime area for injuries is the insertion on the tuber calcanei or directly proximal. One defers between complete and partial ruptures, acute and chronic injuries as well as displacement of the tendon of the superficial digital flexor muscle. In 38 cases (33 dogs and five cats) the clinical examination, radiology, ultrasonography and therapy are shown. Usually the clinical examination is sufficient for a diagnosis (hyperflexion of the hock and weight-bearing on the plantar surface of the metatarsus). The radiology primarily shows up abnormalities on the calcaneus, mineralisations of the tendon and allows the assessment of implants. Ultrasonography is the diagnostic imaging of choice for judgement of tendon diseases as well as the progress of their healing. Tendon suture is advisable if the rupture is open, fresh and/or complete and in cases of luxation of the superficial digital flexor muscle. Immobilisation of the tarsus in hyperextension seems to be of utmost importance no matter if an operative or conservative therapy is chosen.     

Repair of neglected Achilles tendon ruptures with Marlex mesh

An 11-month-old female infant presented with mild fever, hypernatremia, microcephaly, and growth and developmental delay. No sign of thirst was noted in this infant even when the osmolality was over 318 mOsm/kg. Magnetic resonance imaging demonstrated a lobar type holoprosencephaly. Plasma osmolality levels returned to normal after forced hydration and administration of a vasopressin analogue. These findings suggested holoprosencephaly may be associated with a defect in the hypothalamic osmoreceptors that control thirst and vasopressin secretion.     

Rehabilitation of tendon injuries in sport

Clinicians are faced with a growing number of athletes with injured tendons. Treatment of both acute and chronic injuries has proven to be quite complex. It is difficult to maintain the balance between resting the injured tendon and preventing atrophy of the surrounding muscles and joints. Questions also arise as to when the tendon should be strengthened and when the athlete is ready to return to full activity in sport. Through an awareness of the structural and mechanical properties of the tendon, an exercise programme for the rehabilitation of tendon injuries has been developed. It is recommended that this programme be used in combination with ice and other physical modalities. This approach will resolve most tendon injuries within 6 weeks of its implementation. The use of anti-inflammatory medications and surgery can only be recommended in select situations where more conservative measures are inadequate.     

Ultrasonography in the differential diagnosis of Achilles tendon injuries and related disorders. A comparison between pre-operative ultrasonography and surgical findings

OBJECTIVE: This analysis examines 1-year transition probabilities and baseline predictors for suicidal behaviors in young adolescents. METHOD: Adolescents from a two-stage, community-based longitudinal study were classified into suicidal behavior categories (attempt, plan, ideation, and none) for baseline and follow-up years. Transition probabilities for movement among categories were calculated, and polytomous logistic regression analysis was used to examine predictors of suicidal behaviors. RESULTS: Among those with no suicidal behaviors at baseline, 1-year incidence rates were 1.3% for attempts and 1.7% each for plans and ideation. Increasing family cohesion was protective for suicide attempts (odds ratio [OR] = 0.9). Female subjects were more likely than males to report plans (OR = 8.9) and ideation (OR = 4.1). Increasing impulsivity (OR = 2.3), prior suicidal behavior (OR = 10.6), and undesirable life events (OR = 1.1) were significant predictors of plans. CONCLUSIONS: While there are a number of predictors of suicidal behaviors, the false-positive rate is high. Focusing on proximal risk factors, particularly stressors in adolescent development, may overlook the fundamental role of underlying mental disorder and familial factors--both biological and environmental. Suicide and suicidal behaviors are the result of a constellation of adverse factors requiring a range of interventions for prevention.     

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.     

Subcutaneous suturing of the ruptured Achilles tendon under local anaesthesia

Debate concerning the appropriate treatment of ruptures of the Achilles tendon still continues. Conservative treatment can be associated with a high incidence of re-rupture and with relative weakness and lengthening of the triceps surae but with low costs. Surgical treatment contributes to a much lower incidence of re-rupture but can be associated with significant complications as well as with time loss and high costs of hospitalization. Subcutaneous reconstruction combines the advantages of surgical and non-surgical management. Operating with local anaesthesia reduces hospitalization time and operative costs; there are also almost no contraindications for the operation. The functional results in 36 patients operated on in this way are encouraging.     

Conservative treatment of fresh subcutaneous rupture of the Achilles tendon

Primary malignant melanoma of the uterine cervix in a 70-year-old Negro female is reported. Only 9 other cases have been reported in the literature. The diagnosis, prognosis, and modern trends in therapy for this lesion are discussed.     

Methods and rationale for closed treatment of Achilles tendon ruptures

A method of closed treatment of Achilles tendon ruptures by casting, utilizing a long leg cast for 6 weeks and a short leg cast for 4 additional weeks, is presented. An experimental model using rabbits supports the clinical contention that closed approximation and immobilization of Achilles tendons allows tendon healing to progress, at least in the early stages. Observations made on the tendon sheath during early healing attribute a very positive role to it in providing needed blood supply to the tendon. The importance of maintaining a smooth gliding surface as well suggests that the tendon sheath should not be violated by surgical repair on the Achilles tendon.     

Long survival with metastatic clear cell sarcoma of the Achilles tendon

Clear cell sarcoma of tendons and aponeuroses is a rare tumor with a predilection for the lower extremities, particularly the foot. Although it is claimed to have a poor prognostic outlook, it is sometimes characterized by a slow clinical course. The authors report a case with a prolonged survival period of 7 years--5 years in the presence of multiple lung metastases.
