The timing of epiphysiodesis. A comparative study between the use of the method of Anderson and Green and the Moseley chart.

This retrospective study compares two groups of patients who underwent an epiphysiodesis for leg length discrepancy. In group A (47 patients) the timing of the epiphysiodesis was calculated using the method of Anderson and Green; in group B (36 patients) the Moseley chart was used. A leg length discrepancy of 1.5 cm or less at maturity was considered a satisfactory result. Group A showed 51% good results, group B 63.9%. In both groups, an important source of the poor results was error in calculation and prediction: 30.4% in group A (or 15% of the total), 61.5% in group B (or 22% of the total). The percentage of patients presenting too late was also considerable and accounted for 34.8% of the poor results in group A and for 23.1% in group B. The unpredictability of growth rate is a lesser problem in group B (15.4% of the poor results) than in group A (30.4%). If the uncontrollable causes of poor results are omitted, only 18% of the poor results in the total group of patients could be accounted for by miscalculation.

Diffuse pigmented villonodular synovitis of the shoulder. A case report & review of literature.

The combination of a diffuse pigmented villonodular synovitis and a rotator cuff tear of the shoulder in a 64-year-old man is described. The patient was treated by complete synovectomy, open repair of the rotator cuff tear and a Neer acromioplasty. Six months after this surgical treatment the patient was free of pain, and clinical examination revealed an almost normal range of motion.

Radial ray deficiency and ulnar ray deficiency in two sibs.

A kindred with a diabetic mother is described with one sibling with a radial deficiency (type 1 radial dysplasia (Bayne) with a hypoplastic thumb type 3 of Blauth) and one with an ulnar ray deficiency (type 2 of Ogden or type 1 of Swanson). A metabolic cause is probable, although the diabetes was well controlled during pregnancy.

The syndrome of Parsonage and Turner. Discussion of clinical features with a review of 8 cases.

A clinical analysis of 8 patients with brachial plexus neuropathy is presented. The disease may involve the upper, the lower, or the entire plexus. There is a higher incidence in men than in women. The syndrome is not uncommon but is frequently diagnosed incorrectly. The fairly typical pattern of symptoms and signs includes sudden onset with severe pain along one side of the shoulder girdle, followed in a few hours or days by atrophic paralysis of muscles over the affected shoulder. The disorder is occasionally bilateral. The paresis persists for months or even years. The overall prognosis is excellent despite the severity and extent of the lesion. The etiology is unknown, but decreased physical resistance is a predisposing factor.

In situ posterolateral fusion for spondylolisthesis.

In this series spondylolisthesis was treated operatively in children and adolescents who had a displacement greater than 50% even if they were asymptomatic. In youngsters with less than 50% displacement and in adults, operative stabilization was performed if the displacement was progressive or if there were persistent symptoms unresponsive to conservative treatment that interfered with the patient's normal activities. The operation consisted of a posterolateral fusion in situ. Usually a laminectomy was not performed unless there were signs of severe neural compression. No reduction of the spondylolisthesis was attempted. We reviewed 38 cases treated operatively with a mean follow-up of 7 years. Twenty patients were younger than 20 years at the time of operation and 10 of these had greater than 50% displacement. The results were good to excellent in 90% (18 patients). In the adult group (18 cases) the results were less favorable, but still good to excellent in 72% (13 patients). In the adult group pseudarthrosis frequently occurred at the L4-L5 level. There were no neurologic complications postoperatively. Fusion in situ for spondylolisthesis is a safe operation giving satisfactory results.

An overview of implant materials.

Materials used for implant manufacture may play an important role in implant fixation. The choice of a material influences rigidity, corrosion characteristics, biocompatibility and tissue receptivity. The surface morphology of the implant affects its stability within the skeleton or within the surrounding cement mantle. This paper summarizes materials used in orthopedic implants, including metals and metal alloys, polymers and ceramics.

Shoulder impingement syndrome.

An analysis of the results of 53 patients treated by an open Neer decompression for chronic impingement of the shoulder is presented. Patients were evaluated pre- and post-operatively on the UCLA Shoulder Rating Scale, which includes an assessment of pain, function, range of motion, strength and patient satisfaction. After an average period of 27.3 months, good or excellent results were found in 81.1%. Satisfactory results (according to Neer) were found in 94.3%. Differential diagnosis of acromioclavicular pathology and cervical syndromes is important.

Ultrastructural changes in synovium and cartilage in experimental hemarthrosis in dogs.

This paper reports electron-microscopic findings in synovium and cartilage in experimental hemarthrosis in dogs. The results are correlated with the total amount of glycosaminoglycans in the cartilage matrix, measured by the fixed-charge density method. Very early, changes are seen in the synoviocytes, similar to synovitis, and especially phagocytosis of iron-containing particles forming secondary lysosomes or siderosomes. Siderosomes are also a constant feature seen in the chondrocytes, together with changes in the rough endoplasmic reticulum and in the glycogen content, correlating with the changes in the ground substance.

Conservative versus neurosurgical treatment of tethered cord patients.

We compared the outcome of neurosurgical release of a tethered spinal cord in 20 children with the neurological evolution of 21 other children known iwth a tethered spinal cord on nuclear magnetic resonance scan (NMR). Neurosurgery yielded stabilisation of the symptoms without any lasting improvement. Pre-operative conservative medical treatment had to be continued in all operated children. Three of the 20 operated children are showing signs of retethering despite appropriate neurosurgery, indicating that retethering should be considered as a major and frequent complication. In the majority of our children, symptomatic (re)tethering was recognised by the appearance of increased tendon reflexes and a progressive pes cavus, suggestive of an upper motor neuron disease involvement.

Triple arthrodesis in neuromuscular disorders.

Triple arthrodesis, consisting of a fusion of the calcaneo-cuboid, talonavicular, and talocalcaneal joints, is used to correct deformity and replace braces. Indications depend on symptoms. For good results, patients should be at least 12 years old. A review of 25 cases shows that a varus deformity usually does not give good results, a pseudarthrosis always had a poor outcome, and patients are usually more satisfied than the surgeon with the result.
