Epithelioid sarcoma.

Epithelioid sarcoma is a malignant soft tissue tumor characterized by its propensity to occur in the distal extremities as a nodular lesion and its slow and asymptomatic growth. Microscopically, the diagnosis is difficult. Therefore the interval between onset of symptoms and diagnosis averages one to three years. 10 years survival after onset are not uncommon whatever the treatment chosen. Having to treat such a tumor of a hand, 8 years after onset, we decided a local radical excision by micro-surgery instead of amputation or mutilating excision. Long standing clinical follow-up will add valuable information as to the cure of the upper extremity.

[Arthrodesis of the interphalangeal joint of the thumb: indication, technic, results].

A series of 32 arthrodeses of the interphalangeal joint of the thumb has been reviewed and the results are presented. Using a figure-of-eight wire and two crossed K-wires, the tension band principle is observed. Thus, with a minimum of material, durable stability is achieved that permits reliable healing and early use of the thumb under increasing load. The morbidity is reduced to a reasonable duration of five weeks. The angle of arthrodesis should be adapted to the professional requirements: Instrument grip (large or disc grip) is best with a small angulation of 5 to 10 degrees, while for precision grip a larger angle of 20 to 30 degrees is preferred. Tactile gnosis is best preserved when pronation of 5 to 10 degrees and slight ulnar deviation of 5 degrees of the distal phalanx in relation to the proximal phalanx is achieved. For ten years, the H-shaped incision has been used with good results in our department. However, some patients have shown anesthetic skin areas distal to the incision. We therefore have changed to a fork-shaped incision, which better preserves the cutaneous innervation.

[Ischemic necrosis of the deep extensors of the forearm: a rare compartment syndrome].

The ischemic compartment syndrome is thought to develop following an unphysiological pressure increase in one of the numerous muscular compartments of the extremities, confined by bone surface and strong fascia. Pressure-induced ischemia may cause partial or total necrosis of the vulnerable structures in the compartment. This ischemic compression syndrome was found in the deep extensor compartment of the distal forearm in a young female patient following osteotomy of the ulna. The syndrome at this rather unusual site was not diagnosed and treated in the acute phase. Resection of fibrotic, contracted musculature (extensor indicis proprius, extensor pollicis longus and brevis and abductor pollicis longus) and tendon transfer were performed to restore useful function.

[Stable osteosynthesis and autologous bone graft in compound hand fractures with bone defects].

The use of large cortico-cancellous bone grafts in reconstructive surgery of the skeleton of the hand had been greatly facilitated by the advent of stable internal fixation techniques. In cases with bone-defects or large areas of comminution there is less hazard in using primary bone grafts rather than pursuing pain-staking open reduction and fixation of small fragments. When numerous structures are severely injured, primary reconstruction of skin and tendons is dependent upon sound primary reestablishment of bony continuity. Aftercare is then directed exclusively to the demands of the non-bony structures which have been repaired.

[Several years' experience with thumb saddle joint prosthesis by the de la Caffinière method].

This type of endoprosthesis was used for four years in chronically painful idiopathic osteoarthritis of the carpometacarpal joint of the thumb. Our results match exactly those published by the originator of the endoprosthesis CAFFINIERE, i.e. 70% excellent results, nearly 30% problem cases. The problem of loosening of the stem or the cup of the prosthesis seems to depend in our cases on the operative technique rather than on the design or other factors. In the rheumatoid patient as well as in polyarthrotic hands we cannot encourage the prosthetic replacement of the carpometacarpal joint of the thumb.

[Spontaneous osteolysis of the carpus (Gorham syndrome?)].

Osteolysis following trauma (vanishing bone) is well known. Its appearance is not typical to any special anatomical site. A massive osteolysis of the carpus was described by GORHAM in 1955. In subsequent years this type of osteolysis was found together with progressive nephropathy. The author presents a case of exclusively carpal osteolysis without initial trauma, not accompanied by nephropathy, starting out at the age of six. The carpal bones were completely destroyed by the age of eleven.

[The idiopathic osteolysis syndrome].

Idiopathic osteolysis of the multicentric type is a rather rare clinical entity without known causative factor at onset. It displays rapid clinical progression and destruction of bone is completed before the end of growth. A review of the literature is presented with a view in particular to useful classification of the different types of osteolysis. A case followed up at our clinic for surgery of the hand is described and discussed.

[Kirner's deformity: an isolated malformation of the third phalanx of the little finger].

A typical growth deformity of the third phalanx of the 5th finger known in the literature as "Kirner's deformity" has been observed over 5 years in 4 patients (there are now 5 patients) at the Clinic for Hand Surgery in St. Gall. Almost all reports (39 cases) are in the English-language literature. It is felt that apart from esthetic problems functional deficiency is of considerable relevance, and the only existing therapy mentioned in the literature (osteotomy) has been supplemented by localized partial epiphysiodesis by microsurgical operative technique.

Stabilization of bone in replantation surgery of the upper limb.

The principles of sound osteosynthesis of the skeleton of the hand are the same as in internal fixation of other bones. Small implants and instruments are essential. In replantation surgery healing of microvascular anastomoses and nerve sutures as well as repaired tendons is possible when the skeleton is stabilized. Only the minimum metal should be implanted to avoid interference with joint and tendon function. A small implant can provide an adequate stability, when it is applied correctly. Replantation should be performed only by surgeons with extensive experience in the field.
