Enzyme histochemical alterations in human skeletal muscles after tenotomy and after spontaneous rupture of the tendon.

The authors studied the histochemical alterations of human skeletal muscles after tenotomy and after spontaneous rupture of the tendon. Both succinate dehydrogenase (in type I fibers), and myofibrillar ATP-ase (in type 2 fibers) activity was decreased in all injured muscles. In the intact antagonists and contralateral muscles alterations were not found. The creatine phosphokinase and aldolase activity were decreased also in injured muscles. The lactate dehydrogenase activity was various both in affected and in unaffected muscles. Two weeks or more after the injury of the tendon in injured muscles the number of type 1 fibers were decreased and therefore a mathematically significant type 2 fibre predominance occurred. Atrophy involve both type 1 and type 2 fibers, but type 1 fibre atrophy was more pronunced as type 2 fibre atrophy.

[Effect of adductor tenotomy on the hip joint in spastic paralysis].

Author examined the effect of adductor tenotomies in spastic patients. The changes of passive abduction, of the shaft-neck angle, of Wiberg's angle and of the decentric distance are evaluated following the operation. It was found that the change of the supplementary development of the acetabulum decreases with the time. With this operation the scissoring gait and the subluxation of the hip can be eliminated.

Minimal incision tenotomy for hallux interphalangeal joint extensus.

The spoon-toe hallux deformity causing symptomatic hallux pathology can be corrected through a minimal incision stab tenotomy of the extensor hallucis longus tendon that is usually performed at the level of the interphalangeal joint. This procedure is recommended rather than a traditional tenoplasty because it creates very little disability, successfully reduces the deformity, has low incidence of complications, and produces lasting results in maintaining the correction. The procedure can be used as both a solo procedure or in conjunction with other procedures on the hallux.

Hallux tenotomy-capsulotomy.

The deformity of the hallux that is described in this article is most probably more common than we realize and is often seen in patients with mycotic nails and subungual exostosis. This pathology is easily corrected with a tenotomy-capsulotomy at the level of the distal interphalangeal joint. This procedure, when accomplished as described, does not affect the function of the hallux at the level of the metatarsophalangeal joint.

Long-term results of open sternocleidomastoid tenotomy for idiopathic muscular torticollis.

At the end of their skeletal growth, we evaluated the cases of sixty-seven patients who had had an open tenotomy of the sternal and clavicular origins of the sternocleidomastoid muscle for idiopathic muscular torticollis. The average length of follow-up was 15.4 years, and the average age at the last follow-up was 23.9 years. The patients were divided into three groups according to their age at the time of operation. Group I consisted of patients who were operated on between the ages of five months and six years; Group II, of patients who were operated on between the ages of seven and eleven years; and Group III, of patients who were operated on when they were twelve years old or older. According to our method of evaluation, 37 per cent of the patients had a good, 45 per cent had a fair, and 18 per cent had a poor result. The patients in Group I had the best results and those in Group III, the worst. In general, the patient's age at operation, the duration of the disease, and the severity of the deformity before the operation had the major effects on both cosmetic and functional results.

[Spasm of the adductor muscles, pre-dislocations and dislocations of the hip joints in children and adolescents with cerebral palsy. Clinical observations on aetiology, pathogenesis, therapy and rehabilitation. Part II. The importance of the iliopsoas tendon, its tenotomy, of the coxa valga antetorta, and correction through osteotomy turning the hip into varus (author's transl)].

The following factors besides spasm and contraction of the adductor muscles contribute to the occurrence of dislocations of the hip in spastic paralysis: Spasm and contraction of the iliopsoas muscle and enhanced valgus position and antetorsion. The author holds the opinion that in case of malformation of the proximal end of the femur, it is not only the indirect action of the spastic musculature via the proximal femur-epiphyseal cartilage which is responsible for this phenomen in accordance with the law on functional adaption through longitudinal growth (Pauwels), but also the direct traction of the iliopsoas tendon. A clue in this direction is the often very pronounced elongation or enlargement of the trochanter minor. The author demonstrates the pathogenetic importance of iliopsoas contracture and malpositioning of the neck of the femur by means of analyses of the course in two patients. The following principles of treatment are postulated for spastic dislocation of the hip: Elimination of the pathogenetic factors through myotenotomy of the adductor muscles and complete resection of the obturator nerve, with observation of strict aftertreatment criteria, tenotomy of the iliopsoas, repositioning and osteotomy with turning into varus. Osteotomy without previous elimination of the pathogenetically acting muscular forces does not appear useful. Likewise, permanent re-positioning by means of muscle-relaxing operation cannot be sufficiently safe-guarded without additional osteotomy once the dislocation has taken place. In twelve patients with spastic dislocation of the hip, treated in accordance with these guidelines (two without osteotomy) aged 6 6/12 and 19 5/12 years, a roentgenologically good result was obtained in half of the cases, whereas the functional result was satisfactory not only with these patients but also with part of the other patients. If surgical treatment is instituted early enough, and if the experiences described here are taken into consideration, it is to be expected that the results will be even more satisfactory. The corset supporting the seated patient, developed by us, has been found very useful during the aftertreatment stage. A definite stand is taken against the therapeutic nihilism which leaves treatment of spastic dislocations to physiotherapy. It is also pointed out that indication for treatment is not represented only by the target of learning how to walk, but also by providing an overall improvement of the life situation of the patient, by either enabling him, or improving his ability, to sit or by "merely" improving the care of the perineum.

[Changes in lactate dehydrogenase, glutamate-cxaloacetate transaminase and glutamate-pyruvate transaminase in several muscular atrophies. I. Changes following tenotomy].

The activites of lactic dehydrogenase (LDH), glutamicoxalactic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) are investigated within variable periods following tenotomy of m. gastrocnemius in the rat. A gradual fall of total activities is established, mostly significant for LDH, and least - for GPT. The specific activities undergo similar alterations. Experiments with dialysates show that the changes found are due to a reduced enzyme molecules' synthesis, and not to altered ratios between enzyme activators and inhibitors.

Effect of tenotomy and denervation on the early post-exercise glycogen recovery in skeletal muscles of the rat.

The role of passive tension and innervation in the early (1 and 3 h) post-exercise glycogen repletion was studied in different types (fast-twitch-glycolytic (FG), fast-twitch-oxidative-glycolytic (FOG) and slow-twitch-oxidative (SO) rat skeletal muscles. Immediately after a 30 min exercise the rats were anaesthetized and the muscles were subjected to the following surgical procedures: 1) left intact, 2) tenotomized, 3) denervated, 4) tenotomized and denervated. A group of resting rats was handled in the same way. It was found that tenotomy had no effect on glycogen levels in the muscle of resting rats. It, however, delayed the postexercise glycogen repletion in the FOG muscle. Denervation lowered the resting glycogen level only in the FG muscle. It resulted in further reduction of the glycogen level one hour after the exercise in this muscle. In the 3rd hour after the exercise the glycogen level in FG-denervated muscle was equal to that in the intact one. In the FOG and SO muscle denervation affected neither the resting glycogen level nor its recovery after the exercise.

[Pectineus myectomy, tenotomy of the iliopsoas and neurectomy of the joint capsule as symptomatic therapy for coxarthrosis of the dog].

Abduction and extension of the hip is reduced and painful in patients with coxarthrosis. Contracture of the pectineus and iliopsoas muscles restricts the abduction and extension of the hip, respectively. Pectineus myectomy and tenotomy of the iliopsoas muscle result in clinical improvements. This symptomatic therapy is relatively simple, with minimal invasion. Clinical results are satisfactory.

Treatment of the chronic boutonniere deformity by extensor tenotomy.

A patient with a chronic boutonniere deformity often experiences more difficulty because of the hyperextension deformity at the distal joint, rather than the lack of extension at the proximal interphalangeal joint. It is in these cases that restoration of flexion at the terminal joint by tenotomy of the terminal extensor tendon is of most value.

Transection of the superior rectus muscle during intended superior oblique tenotomy: a report of three cases.

Reported complications of superior oblique surgery include postoperative vertical or torsional deviation, Brown's syndrome, head tilt, blepharoptosis, and conversion of an A-pattern to a V-pattern. McNeer reported three cases of postoperative vertical deviation, one of which was attributed to severing of the superior rectus tendon. We report three additional cases of inadvertent unrecognized transection of the superior rectus during intended superior oblique tenotomy to emphasize the importance of direct visualization of these tendons during surgery.

[Prevention of hip dislocation in children with cerebral palsy by early tenotomy of the adductor and psoas muscles].

The effectiveness of early tenotomy of the psoas and adductor muscles for the prevention of dislocation of the hip dislocation in children with cerebral palsy precluding walking was studied in 40 hips in 24 children with severe disability. Age at the time of the procedure ranged from 1 1/2 years to 10 years. Results were evaluated by measuring Reimers' migration percentage (MP). Mean follow-up was three years. A satisfactory outcome (at least 10% improvement in MP at last follow-up) was seen in 67% of cases. The study of correlations with age and degree of displacement at surgery showed that results were satisfactory in 90% of children who had surgery before 4 years of age and whose MP was under 33%. To have preventive value, this procedure should be carried out at 2 years of age, before development of dislocation of the hip.

Percutaneous longitudinal tenotomy in chronic Achilles tendonitis.

In the period from August 1989 through December 1992, 42 track and field athletes with unilateral Achilles tendonitis and/or peritendinitis were operated using multiple percutaneous longitudinal tenotomy under local anesthesia following failure of conservative treatment. Patients were reviewed in a special clinic over three consecutive days at an average of 19.2 (9.4) months from the operation. Of the 42 patients operated, 36 (86%) attended. On this occasion, only subjective assessment was carried out. Of the other six patients, four were interviewed by telephone using the same questionnaire; two were lost to follow-up. The results in 25 patients (59.5) were rated as excellent, 11 (28.2%) as good, 4 (9.5%) as fair, and 2 (4.8%) as poor.
