The Tikhoff-Linberg procedure in the treatment of sarcomas of the shoulder girdle.

The majority of patients with soft tissue or bone sarcomas of the upper extremity can be treated today with limb-saving procedures using combined modality therapies. For patients with a tumor in the shoulder area, sometimes an interscapulothoracic amputation is the only radical surgical treatment. However, in selected cases, in which the tumor does not involve the neurovascular bundle, a limb-sparing alternative might be the Tikhoff-Linberg resection. Normal function of the hand and forearm, with reasonable function of the elbow, can be maintained by this procedure. Four case histories are reported.

Walking speed of normal subjects and amputees: aspects of validity of gait analysis.

This study investigated some aspects of the validity of walking speed recording in 15 normal subjects, 16 trans-femoral amputees and 8 knee disarticulation amputees. The variability and test-retest reliability of walking speed and the influence of simultaneous recording of EMG and goniometry on comfortable and fast walking speeds were studied. The variability between sessions was mainly determined by the variance within each session. The variance of speed within sessions while walking with fast speed, was higher when walking without equipment than when walking with equipment. The variances of speed within sessions of the normal subjects were higher than those for both amputee groups. The test-retest reliability, expressed by the intra-class correlation coefficient, was good: between 0.83 and 0.98. The speed when walking without equipment was significantly higher both in normal subjects and amputees than the speed when walking with equipment.

The interscapulothoracic amputation in the treatment of malignant diseases of the upper extremity with a review of the literature.

The majority of patients with soft tissue sarcoma (STS) or bone sarcomas (BS) of the upper limb can be treated today with limb saving procedures using combined modality therapies. However, for a small group of patients the interscapulothoracic (IST) amputation is the only final surgical treatment with either a curative or a palliative intent. Since 1972, 12 patients seven males and five females, median age 36 years (range 13-82) underwent an interscapulothoracic amputation; five for bone sarcomas, five for soft tissue sarcoma and two for locoregional metastases. There was no post-operative mortality or morbidity. During a median follow-up of 8 years (range 0.25-15), there was no local recurrence. The five-year survival rate for the soft tissue sarcomas was 80% and for the bone sarcomas 30%. The interscapulothoracic amputation is one of the major ablative surgical procedures which should be performed with curative intent, very rarely with a low palliative intent. The prognosis of an interscapulothoracic amputation for shoulder girdle malignancies is not different from extremity soft tissue sarcomas or bone sarcomas located more distally. The morbidity and local recurrence rate after interscapulothoracic amputation should be negligible.

The feasibility of hind foot amputation in selected sarcomas of the foot.

The treatment of foot sarcomas is generally a below knee amputation. In selected sarcomas of the forefoot, however, a transtarsal amputation according to Chopart, a calcaneotibial arthrodesis according to Pirogoff, or a supramalleolar amputation according to Syme can be considered the treatment of choice, leading to an optimal functional outcome.

[Ectopic bone formation: prevention, diagnosis and treatment].

Two patients are described who developed heterotopic ossification after a minor trauma. The clinical symptoms, pathophysiology and treatment are discussed. We conclude that disabilities and handicaps will be limited by rehabilitation, which includes training of still available functions, and compensation for the lost functions by offering adaptive equipment and adjusting the circumstances. The treatment of patients with heterotopic ossification requires a multidisciplinary approach.

The effect of low-frequency electrical stimulation on denervation atrophy in man.

The effect of low frequency electrical stimulation (LES) on denervation atrophy and recovery of the muscles was examined in a group of 73 patients with a single or a combined total lesion of the median, ulnar or peroneal nerves. The differences between the patients were evaluated by means of clinical muscle force testing, EMG, dynamometry (ulnar and median nerve lesions), computer tomography (ulnar nerve lesions) and ultrasonography (median and peroneal nerve lesions). A beneficial effect of LES could not be shown.

Outcome in elderly injured patients: injury severity versus host factors.

To evaluate the differences between the outcome of elderly patients with severe injuries and that of their contemporaries with a less severe injury, we reviewed 42 severely injured elderly patients and compared them with 76 patients with a femoral neck fracture. We analysed the influence of injury severity and host factors (age, sex and pre-injury medical status) on outcome. The in-hospital mortality rate was 31 per cent in the severely injured patients and 3 per cent in those with a femoral neck fracture. Home was the main discharge destination in the severely injured elderly (34 per cent) and a nursing home in patients with a femoral neck fracture (65 per cent). Functional outcome 1 year after injury was better in the severely injured elderly group. Long-term survival was mainly determined by host factors and not by injury severity. Physicians and policy makers should be careful in predicting the outcome of elderly injured patients merely on the basis of injury severity, because host factors are of greater importance.
