שברים בבסיס עצם הטפח החמישית בכף היד אינם שכיחים. הסיבות להתהוותם הן בדרך כלל נפילה על יד מושטת או פגיעה בעקבות חבטת אגרוף. הגישות הטיפוליות הן שמרניות וניתוחיות. בספרות אין הסכמה לגבי הגישה הטיפולית המיטבית. במעקב אחר 14 חולים עם שברים בבסיס עצם הטפח החמישית שנותחו תוך יום ועד ארבעה ימים מהפציעה, נמצא איחוי מלא בכל השברים, טווח תנועות תקין במיפרקי הזרת והיעדר שינויים ניווניים במיפרק הקרפו-מטאקרפי החמישי במהלך שלוש שנים ומעלה ממועד הפציעה.

המטרה במאמר היא לסקור את ניסיוננו בטיפול ניתוחי מיידי בשברים בבסיס עצם הטפח החמישית, תוך שימת דגש על המצב האנטומי הייחודי של המיפרק הקרפו-מטאקרפי ועצם הטפח של הזרת וההשלכה התיפקודית שיש לכך על החולה, וכן סקירת הספרות המשמעותית לנושא.

Prevalence of hip fractures is increasing world-wide, as the mean age of populations increases. Despite advances in anesthesia, nursing care, and surgical techniques, hip fractures remain a significant cause of morbidity and mortality in the elderly.

We operated on 65 cases of hip fractures from 1995 to the end of 1997: average age was 82.9, 72% were women, average waiting time for operation was 1.6 days, perioperative mortality was 3.5% and postoperative mortality 26.2%.

Osteoarthritis results from progressive catabolic loss of cartilage proteoglycans due to imbalance between synthesis and degradation. The availability of glucosamine, an intermediate in mucopolysaccharide synthesis, can be rate-limiting for proteoglycan production in cartilage tissue culture.

57 patients suffering from osteoarthritis of the knee were randomized into a group treated for 4 weeks with daily IV glucosamine sulfate (GS) together with 800 mg chondroitin sulfate, and a placebo group. Knee pain at rest, on movement and on palpation, as well as range of knee motion were then recorded.

In the GS group, there was significant reduction of clinical symptoms (p<0.01), but no significant reduction in the placebo group. Physicians' assessment of tenderness and range of motion were significantly in favor of the GS group (p<0.01). In those treated with glycosamine there were no adverse reactions and no changes in laboratory blood tests.

It is clear to experts in the health care industry that with regard to medical decision-making, considering costs of medical devices is not a good index, but it is highly important to include medical aspects. This approach guarantees an advance and an appropriate method.

We present a cost-effectiveness analysis to target the optimal strategy of how to use medical diagnostic devices in cases of knee injuries. Today, one of the more common medical emergency referrals seen worldwide is in the area of orthopedics, knee injuries in particular. They can harm soft tissue, bone tissue, or both simultaneously. The diagnosis of soft tissue injury is difficult at best. Among the devices helping the clinician make an accurate diagnosis are MRI and ultrasound (US).

We conclude that US is superior to MRI in this condition. This is especially true when the orthopedic examination leads to the suggestion of arthroscopy. The results were not modified, and a sensitive study of the parameters that influence the decision- making process was undertaken. Decision-makers should not consider medical outcome alone, but should take into account the costs. A clinical study should validate the assumption on which this study was based.

Low back pain radiating to a limb is usually caused by lumbar disc herniation. Tumors of the spinal cord or near the sciatic or femoral plexus can cause neural compression and clinical signs similar to those of disc herniation. Such tumors are usually misdiagnosed as discal herniation and appropriate treatment is delayed. We present 4 men who had tumors causing low back pain radiating to the leg: a 70-year-old with metastatic squamous cell carcinoma of the lung, a 20-year-old with aneurysmal bone cyst of the vertebral column, a 52-year-old with retroperitoneal sarcoma and a 32-year-old who also had retroperitoneal sarcoma. Diagnosis and trwere delayed because the clinical symptoms were ascribed to lumbar disc herniation. The latter 2 patients had CT-scans showing lumbar disc herniation, but similar findings are common among asymptomatic individuals.

The differential diagnosis of low back pain radiating to the leg should include tumor when there is a history of cancer, pain not relieved by conservative treatment nor by lying down, pain is increased at night, pain accompanied by weight loss, and when physical examination demonstrates injury to more than 1 nerve root. In these circumstances work-up should include EMG, radioisotope scan and CT of the pelvis.

Trauma increases risk of thromboembolic complications. Thus, in pelvic fractures and spinal injuries the incidence of deep vein thrombosis (DVT) is about 35-60%. Half occur in the pelvic veins and are the most likely to result in pulmonary embolism. While symptomatic pulmonary embolism occurs in 2-10% of patients, more have silent pulmonary embolism. 0.5-2% of pulmonary embolisms are fatal. In lower extremity trauma the incidence of DVT is about 58%, with 18% of them in the proximal veins. Thromboembolic complications are the prime cause of morbidity and mortality among trauma patients, yet they can be prevented efficiently and cost-effectively. The arsenal of prophylactic agents includes heparin, low molecular weight heparin, and mechanical devices including inferior vena cava filters.

Scapular pain is a common complaint in daily orthopedic practice. A different type of scapular discomfort, the snapping scapula syndrome that occurs when smooth gliding motion of the scapula upon the chest wall is interfered with is much less common.

We studied the syndrome of periscapular pain and discomfort, and present a rare etiology: elastofibroma dorsi, a unique, benign, soft tissue-tumor with unique characteristics.

Elastofibroma appears deep to the lower scapular pole, is often bilateral, and consists of a mixture of collagen, elastic fibers and fibroblasts. We present 6 cases, in 3 men and 3 women aged 51-65.

Soft tissue sarcomas are exceedingly rare, making up less than 1% of all solid malignancies. In the retroperitoneum, they tend to be large when diagnosed and are a therapeutic challenge to the surgical oncologist. Our experience with 51 patients with retroperitoneal sarcomas operated on during the past 4 years is presented. 37 were primary and 26 presented as recurrent tumors. The group included many different histological sub-types, the majority being high grade tumors.

Complete resection was achieved in 84%, necessitating extensive surgery, but was not possible in 8 patients (16%) who underwent partial resection or biopsy only. There was 1 perioperative fatality (2%). 18 (35%) suffered complications, all of which were reversible. The estimated 5-year survival in the complete resection group is 40%, while none of those who underwent partial resection survived more than 2 years. There was significantly better survival in patients with primary, low grade sarcomas which were smaller than 8 cm, compared to those with high-grade, recurrent sarcomas larger than 8 cm. Local recurrence developed in 8 patients of the complete resection group (18%), 2 months to 3 years after surgery.

These data show that despite the concept of retroperitoneal sarcomas as being aggressive, invasive tumors with a poor prognosis, the prognosis is not unusually bad. With proper surgical technique, resectability may be high, with improved overall survival.

CT-guided excision of osteoid osteoma is a new surgical technique that enables accurate resection of the nidus during 1-day hospitalization. We present 5-year results in 42 patients (26 males and 16 females, mean age 18 years, range 3-46). In 40 out of 42, complaints disappeared immediately after the procedure. The recovery period was short and the return to normal activity was faster than in the open surgical approach. Complications were minimal and transient.

Nerve paralysis following the use of tourniquets, regular or pneumatic, for limb surgery is rare. We describe a 19-year-old male soldier who had tourniquets applied for 3 1/4 hours to his arm and both legs due to penetrating injuries. As a result, he suffered palsy of the radial nerve and both common peroneal nerves. Nerve palsy in such cases has not been described in the literature. It is not clear whether the cause is direct mechanical pressure on the nerve, nerve ischemia, or a combination of both.

We recommend that tourniquets should not be used continuously for more than 2 hours. If evacuation of the injured is delayed, the medical team should consider loosening tourniquets for short intervals or changing for a pressure bandage. This is providing the patient's condition is stable and bleeding does not start again on release of the tourniquet.

A 42-year-old man was admitted for fever and severe low back pain radiating to both legs. On MRI, an epidural spinal abscess from S1 to D10 was seen. Treatment included laminectomy, drainage of the abscess and antibiotics. Recovery was complete without neurological damage. Increased awareness of this disease may lead to diagnosis and treatment.

Lymphoma of the Knee Joint Simulating Patellar Fracture

Orthopedics Dept., Shaare Zedek Medical Center, Jerusalem

Fracture of the patella is not uncommon after direct anterior knee trauma. However, there are other medical situations that resemble it radiologicaly. We present a patient mistakenly diagnosed as having a patellar fracture who had primary, solitary, malignant B-cell lymphoma of the knee space eroding the lower pole of the patella. We have found no reports of such a lesion in the literature. Another commbenign condition that might erode adjacent bone is chronic synovitis. Our patient was treated withchemo- and radiotherapy and the lesion fully regressed with no evidence of local or systemic recurrence 1.5 years after diagnosis.

During routine emergency room work penetration by foreign objects is frequently encountered, some of which may be very irregular in shape. These may cause further damage if inappropriately removed. It is important to perform a proper X-ray survey.
