A clinical and histologic analysis of failed fresh osteochondral allografts.

Fresh small osteochondral allografts were implanted in 108 patients. A clinical and histologic analysis was undertaken in 18 patients whose grafts failed and were excised. Twelve of these patients had evidence of viable hyaline cartilage despite adverse conditions. If careful attention is given to patient selection, age, appropriate timing for correction of alignment, and meticulous technique associated with graft positioning, size, and thickness, then the incidence of clinical failure should be minimized.

Distal femoral varus osteotomy for valgus deformity of the knee.

Twenty-four patients who had degenerative arthritis of the lateral compartment of the knee that was associated with a valgus deformity and a superolateral tilt of the joint line were treated by distal femoral varus osteotomy. A surgical technique that was designed to produce a horizontal joint line and a tibiofemoral angle of zero degrees is described. At an average length of follow-up of four years, twenty-two of twenty-four patients had a successful result as judged by our protocol for evaluation. One osteotomy had to be revised for failure of fixation, and one patient had a pulmonary embolism that had a satisfactory outcome after the administration of anticoagulants. One patient required manipulation of the knee at six months. The simple surgical technique that we used was effective in realigning the femoral with the tibial axis in patients who had a valgus deformity of the knee, a superolateral tilt of the joint line, and osteoarthritis of the lateral compartment.

Keller arthroplasty: a prospective review.

A prospective study of the Keller procedure for hallux valgus was carried out on 44 female patients (75 feet) with an average age of 66 years. The average follow-up was 31 months (range, 12-64 months). The operation was effective in improving symptoms (joint pain and bunion tenderness), cosmesis, function (footwear and level of activity) and in decreasing the deformity. The operation did not have an influence on metatarsal calluses. Cock-up deformity was common postoperatively but did not affect the results. The overall patient satisfaction rate was 77%.

Asymmetric epiphyseal distraction in treatment of Blount's disease.

A 10-year-old boy with Blount's disease was treated by asymmetric distraction of the proximal tibial epiphysis to correct varus deformity of 12 degrees. Gradual hemichondrodiastasis with immediate mobilization resulted in slight overcorrection of the deformity with no complications.

Arthroscopic treatment of osteochondral lesions of the talus.

In a study of twenty-four patients (twenty-four ankles) with a symptomatic osteochondral lesion of the talus, eighteen of the lesions were found to be associated with trauma. The lesions were evaluated both radiographically and by arthroscopy. The method of treatment was determined at arthroscopy by observing the nature of the articular cartilage overlying the lesion. The cartilage was graded from I to III based on its appearance. It was found that a lesion can progress from grade I to grade III while under observation. There was a lack of correlation between the radiographic appearance and the findings at arthroscopy. The results after an average length of follow-up of thirty months (range, twenty to forty-four months) indicated that osteochondral lesions over which the cartilage is intact (grade I) are best treated by simple restriction of sports activities. Lesions in which the overlying cartilage is soft (grade II) can be treated through the arthroscope by drilling and those in which the overlying cartilage is frayed (grade III) can be treated through the arthroscope by curettage, with minimum morbidity and good results.

Ski injuries in 1976-1982: Ybrig region, Switzerland.

An analysis is presented of 1763 consecutive injuries that occurred in the Ybrig region in Switzerland, a ski resort, during the 1976-1982 ski seasons. The study included all persons injured while skiing and treated at the emergency care facility at the base of the Ybrig region. Fractures were the most frequent injury. Over the years, a decrease in the total number of injuries was noticed. The severity of the injuries was increased. More attention should be paid to the individual preparation of the skier.

Ankle arthroscopy.

Arthroscopic assessment of the ankle joint can be an important diagnostic aid for intra-articular pathologic conditions. The major portals of entry are anteromedial and anterolateral. In one patient with loose bodies of the ankle, the authors successfully localized the loose bodies and determined the status of the articular surface by arthroscopy. In a second patient with pain and a roentgenogram suggestive of an osteochondral fracture, arthroscopic evaluation determined that the articular surface was intact, and the patient was successfully treated non-surgically. Precise indications for arthroscopy of the ankle have not yet been determined, but its role will certainly be less extensive in the ankle than in the knee.

Lower limb injuries in parachuting.

Parachuting injuries commonly result from inaccurately performed landing. Alteration of the vertical force absorption pattern to a rotational one is suggested as their major cause. Special attention to the flexed body position and adduction of the lower limbs while gliding and landing can prevent those injuries.

Use of radionuclide method in preoperative and intraoperative diagnosis of osteoid osteoma of the spine. Case report.

A 24-year-old man with persistent low back pain and right sciatica, was found to have an osteoid osteoma of the right pedicle of the second lumbar vertebra. 99mTc-MDP bone scan and CAT scan produced an early diagnosis of the lesion. Intraoperative 99mTc-MDP in vitro combined with imaging and quantitative activity measurements were useful for accurate localization and complete removal. The method is simple and can be performed in every nuclear medicine department, with no need for special operating room facilities.

[Experimental traumatic epiphysiolysis (author's transl)].

Two experimental series of epiphysiolysis, with and without displacement, were performed on 100 young rabbits in each group. The histological site of the epiphysiolysis was demonstrated, and the healing process studied. The basic healing process is induced by the vascular metaphyseal penetration of the separation line, as shown in the epiphysiolysis without displacement. A compensative mechanism appears in the series of epiphysiolysis with displacement, consisting of an epiphyseal vascular penetration of the epiphyseal plate, performing then the embryonal anatomical pattern. The vascular epiphyseal channels close progressively after they reach the metaphyseal vessel. If they do not join the metaphyseal vessels quickly enough, or in sufficient number, they are invaded by osteoblastic cells and fibrous or bony bridges will be created through the epiphyseal plate. These bridges are responsible for growth retardation, axial deviation and even early closure of the epiphyseal plate.

Sequential use of technetium 99m MDP and gallium 67 citrate imaging in the evaluation of painful total hip replacement.

Fourteen patients with 20 total hip joint replacements were studied for 14 painful prosthetic hips. Clinical examination, plain film radiographs and 99Tcm-MDP bone scans failed to differentiate between infection and mechanical loosening of a prosthesis. Sequential use of 99Tcm-MDP and 67Ga-citrate bone scans were performed in an attempt to discover underlying infectious process. Increased focal uptake of both radiopharmaceuticals over the same hip indicated an infectious process responsible for prosthetic loosening. There were no false positive gallium examinations. Sequential use of 99Tcm-phosphate compounds and 67Ga-citrate is recommended for differentiation between mechanical loosening of a prosthesis and loosening of a prosthesis secondary to an infectious process.
