Anterior cruciate ligament reconstruction with the press-fit technique. 2-5 years followed-up of 42 patients.

42 patients underwent anterior cruciate ligament (ACL) reconstruction with the press-fit technique. The ACL was reconstructed with a bone-tendon-bone graft from the medial third of the patellar tendon. The graft was stabilized without screws in the femur and tibia by press-fit. To imitate the anatomical functioning of the ACL, the femoral bone block was placed with the tendon close to the over-the-top position. The tibial block was then placed in a trough on the tibia, so that the ligament fibres were parallel and tight during extension and slightly inverted during flexion. At evaluation mean 41 (25-61) months postoperatively, the mean Lysholm score was 93 (80-100) points, the mean activity level was 6 (3-10) points, and the mean translation of the tibia head, measured by the KT-1000 arthrometer (side-to-side difference), was 2 (0-7) mm. Only 3 of the patients suffered loss of extension (5 degrees). Patients who underwent reconstruction at least 4 months after the injury had better results than those who were operated earlier. The press-fit method allowed for anatomic substitution of the ACL with a stable graft without the disadvantages associated with screws. This method gave early postoperative functioning of the knee and good mid-term results.

Osteoid osteoma in the differential diagnosis of persistent joint pain.

We report 20 cases (13 male and 7 female), mean age 21 years) of juxta-articular osteoid osteoma. The distribution of affected joints was as follows: hip joint (7 cases), knee joint (2 cases), ankle joint (2 cases); iliosacral joint (2 cases), lumbar spine (2 cases), carpus (2 cases), shoulder (1 case), second metacarpal (MCP; 1 case) and first metatarsal (MTP; 1 case). The duration between the onset of symptoms and diagnosis varied from 8 months to approximately 4 years. In juxta-articular osteoid osteoma, the clinical picture and the radiographic findings are often atypical, and this may lead to misdiagnosis and delayed definitive treatment. In young patients with persistent undiagnosed pain, the possibility of an osteoid osteoma should be considered. When the clinical picture is suggestive but radiological findings are negative, we must proceed to further investigation with bone scintigraphy and computed tomography. These examinations should be repeated 1 year after the onset of symptoms because initially negative findings may become positive at a later date. When the diagnosis of an osteoid osteoma is confirmed, surgical excision leads to complete relief of the symptoms.

Application of silicon tissue expanders for the direct or indirect coverage of soft tissue defects in the extremities.

In a 2 year prospective study, 17 tissue expanders were placed on the extremities of 17 patients. The aim was to cover soft tissue defects in the forearm of 8 patients after chinese flap dissection, which was used either as a free or reversed flap. In 8 of the remaining patients, the expanded skin was placed directly on the affected region as a local fasciocutaneous flap. In 1 patient it was determined intra-operatively that the prepared extended skin was not necessary to treat the patient. The tissue expander was successfully used to cover skin defects, both directly and indirectly, in the lower extremity (7 cases) and in the upper extremity (9 cases). Neither infection nor necrosis was observed in the flaps and the cosmetic results, particularly in the forearm, were satisfactory.

Transpositional microsurgery in multiple digital amputations.

In 34 of the 62 patients treated for complete multiple digital amputations, the severed part was not replanted in its anatomical position, but in the place of the most useful stump. This procedure is defined as transpositional digital microsurgery and refers to the transposition and replantation of any digit to another stump which plays a more significant role in the function of the hand. Twenty-eight patients had transposition of a digit, while six patients underwent thumb transposition. All except six of the transposed digits survived, while all of the thumbs survived the surgical procedure. The cosmetic appearance of the hand with a transposed digit or thumb was acceptable to the patients. Two-point discrimination was assessed to be 10-14 mm for the transposed digits, and the functional ability of the transplanted digit was comparable to digits which were replanted in their anatomical position. In conclusion, transpositional digital microsurgery remains a useful alternative for the treatment of multiple digit amputations, particularly in patients with severely damaged non-replantable amputated parts.

Vascularised bone grafts in the treatment of long bone defects.

Reconstruction of large bony defects of long bones was performed using vascularised fibular grafts in four patients at the Department of Orthopaedic Surgery of the University of Ioannina Medical School. Indications for grafting procedures in this small series had been the loss of bone due to the extensive resection of avascular and necrotic bone from septic pseudoarthrosis in three patients and congenital pseudarthrosis secondary to neurofibromatosis in a child. Primary skeletal union with graft hypertrophy occurred in three of the patients. The fourth patient had an asymptomatic nonunion at the proximal end of the graft. The result in each patient was the presence of a well-aligned limb that had normal or nearly normal motion and acceptable length.
