Screw fixation of a complete rotator cuff tear.

Partial and sometimes full-thickness rotator cuff tears can be managed by arthroscopic debridement and anterior acromioplasty. The recent literature on shoulder arthroscopy does not however mention any alternative operation techniques for this very common lesion. We present a case of a distal avulsion of the supraspinatus vendar tendon which was reattached with one screw and washer under arthroscopic control. Indications for this type of fixation are discussed.

Meniscal bearing dislocation in the Oxford knee.

The Oxford knee is a unicompartmental knee prosthesis with a polyethylene meniscal bearing. Anterior dislocation or medial subluxation has been described in lateral compartment arthroplasties. The authors present the case of a medial dislocation of the lateral meniscal bearing and a review of the literature concerning meniscal bearing instability in the Oxford Knee.

Chondral lesions of the patella evaluated with computed tomography, magnetic resonance imaging, and arthroscopy.

In a small series of cadaver knees, experimentally created lesions of the patellar cartilage were compared using contrast computed tomography (CT) and magnetic resonance (MR) imaging. Contrast CT was able to recognize only 50% of the lesions smaller than 3-mm diameter at the first attempt, and none of the lesions of 0.8 mm. MR imaging detected all the lesions, even those as small as 0.8 mm, without use of contrast material. Simultaneously, a prospective clinical study comparing MR diagnoses of chondral lesions with arthroscopic findings was initiated in a series of 54 knees. This clinical study revealed that, concerning patellar chondral lesions, the accuracy of MR imaging compared with arthroscopy (the gold standard) was 81.5%. The sensitivity was 100%, but the specificity only 50% due to the false positives. Reexamination of the MR records enabled us to refine the MR diagnosis and to propose a staging of the chondral lesions. The high rate of false-positive results in our series can be explained by the hypothesis that MR imaging can possibly detect very early lesions, which appear as abnormalities in the deep cartilage layers.

Malignant schwannoma. A case report and review of the literature.

A rare case of a malignant schwannoma presenting as a central fracture-dislocation of the acetabulum is reported. Histological examination showed a high-grade sarcoma. A pleural metastasis was present. A local reconstructive procedure consisting of local tumor excision with an acetabular prosthetic replacement and adjunctive radiation therapy was elected for the patient, who had a short-term prognosis.

CT arthrography and MRI of the patella.

The importance of CT scanning in the diagnosis of patello-femoral disorders is reviewed and illustrated. CT double-contrast technique is compared to Magnetic Resonance Imaging (MRI) using both clinical examples and a cadaver study. The authors demonstrate the superiority of MRI to CT in detecting retropatellar cartilage lesions.

Arthroscopy in the diagnosis of occult dislocation of the patella.

The authors investigated the incidence of acute patellar dislocation by clinical and radiologic examination and by arthroscopy. Acute patellar dislocation represented 2.44% of all knee injuries in their series, and only 25% of the former were evident at the initial examination.

Dome osteotomy of the tibia for osteoarthritis of the knee.

Dome osteotomy of the tibia was performed for osteoarthritis of the medial knee compartment in 54 knees (48 patients). All patients were reviewed after a mean follow-up period of 5-7 years (range: 2 to 10 years). At follow-up, 42 knees (78 per cent) were rated good or excellent, according to the Hospital for Special Surgery Knee Service Rating System (H.S.S.). Twelve knees (22 per cent) were rated fair or poor, according to the H.S.S. score. A highly significant correlation (p less than 0.01) was found between the H.S.S. score and the preoperative grade of osteoarthritis, as well as between the H.S.S. score and the grade of preoperative laxity. Immediate postoperative complications occurred in 19 knees (35 per cent), although without significant influence on the final clinical outcome. Revision surgery had to be performed in 6 knees.

Treatment of unstable intertrochanteric and subtrochanteric fractures in elderly patients. Primary bipolar arthroplasty compared with internal fixation.

Thirty-seven consecutive patients who were more than seventy-five years old and had an unstable intertrochanteric or subtrochanteric fracture were treated by primary bipolar arthroplasty from 1983 through 1986. The functional results, according to the rating scale of Merle d'Aubigné, were rated as good or excellent in 75 per cent of the patients and remained almost unchanged with time. Roentgenographic follow-up showed early bone formation around the extramedullary part of the femoral component. The results in this prospective group of patients were compared with those in a similar but retrospective control group of forty-two patients who were treated by internal fixation from 1979 through 1982 and in whom early full weight-bearing was not possible. In the bipolar arthroplasty group, rehabilitation was easier and faster, and the incidences of pressure sores, pulmonary infection, and atelectasis were significantly lower (p less than 0.05). The early walking with full weight-bearing that the bipolar arthroplasty made possible is considered to be a major contributing factor to these results.

Deep sedation for arthroscopic knee surgery.

Deep sedation was explored in a prospective study of 46 consecutive patients as an alternative to local and general anesthesia. All usual arthroscopic surgical procedures could be completely performed with an inflated tourniquet under this type of anesthesia. Hemodynamic and respiratory parameters exhibited only moderate variations, and returned to baseline values less than 15 minutes after surgery. Recovery of consciousness was faster than with general anaesthesia. Patient satisfaction and operative ease were considered better than with local anaesthesia.

Traumatic haemarthrosis of the knee.

We have investigated a prospective series of 100 acute traumatic haemarthroses of the knee in a general non-athletic population. All the patients had normal radiographs and an aspiration which confirmed the haemarthrosis, before undergoing ligament testing and an arthroscopic examination under anaesthesia. Only one patient had no serious pathology; in the other 99 a total of 193 lesions were recorded. Thirty knees had only one isolated lesion, 69 had combined lesions. This study confirms the serious nature of an acute traumatic haemarthrosis of the knee, even in non-athletic patients.

The Müller acetabular support ring. A preliminary review of indications and clinical results.

A series of 41 total hip arthroplasties with acetabular reinforcement by a Müller support ring is reviewed. The postoperative management was the same as that used in conventional cemented total hip arthroplasty. The overall clinical results and the radiological findings were most satisfactory after one to six years. Of the 30 hips available for functional assessment using the Merle d'Aubigné scale, 16 were excellent, 10 good, 2 fair, 1 poor and 1 bad. These results indicate that, regardless of the primary disorder, the Müller support ring has been helpful when dealing with severe osteoporosis, an acetabular floor lined by bone which does not allow adequate penetration of methyl methacrylate, a small acetabulum needing a small polyethylene socket and localised destruction of the acetabular roof or of the anterior or posterior acetabular pillar. A good result can only be guaranteed if the ring makes a perfect fit with the reamed acetabular cavity.

The use of computerised tomographs in the diagnosis of thoracolumbar injury.

This paper presents four patients with injuries to the thoracolumbar spine assessed by computerised tomography. This technique enabled an easy, quick and accurate diagnosis to be made, avoiding dangerous manipulation of the patient. The scans were analysed using the anatomical classification of Louis to evaluate the instability of the lesions. Control CT scans were used to monitor progress and to provide an accurate prognosis within acceptable limits of irradiation.

SLAP lesions: a retrospective multicenter study.

A retrospective analysis of 530 glenohumeral arthroscopies performed by three independent Belgian arthroscopists revealed the presence of 32 SLAP lesions, which represents an incidence of 6%. Since this is exactly the same percentage as found by Snyder et al., we report our data in this article. We classified 23 of the SLAP lesions using Snyder's classification, 7 needed the additional classification of Maffet et al., and 2 lesions were considered to be anatomic variations; 53% of the lesions were of type II. Concerning the mechanism of injury, we found comparable percentages of traction (22%) and compression (28%) injury as reported by Snyder, but also a high number (25%) of overhead sports activities as described by Andrews et al. Associated lesions were in close accordance with Snyder's data, but a relatively low incidence of rotator cuff injuries (10%) was present. Comparison of treatment regimens showed that the same percentage of lesions (34%) was fixed arthroscopically in both series. Only SLAP II, IV, and V lesions must be considered as unstable and in need of fixation. We confirm that patients' complaints and clinical symptoms are vague and inconsistent. Imaging, using computed tomographic arthrography or magnetic resonance, was performed in a minority of cases. Advantages and pitfalls of both techniques are discussed. Anatomic variations causing an extra-large sublabral hole are shown, and we warn about potential diagnostic and therapeutic errors in these cases.

Comparative radiologic study of the influence of ankle joint bandages on ankle stability.

A comparative radiologic study was carried out to test the stabilizing value of ankle strapping and taping on unstable tibiotalar joints. Unstable ankle joints of 51 athletes were examined without bandages, with strapping, and with taping before and after an activity program. The use of taping proved to give the greatest decrease of the talar tilt (TT) angle. This improvement was greater, even after activity, than the stabilization obtained by strapping before any activity.

Static and dynamic roentgenographic analysis of ankle stability in braced and nonbraced stable and functionally unstable ankles.

Patients suffering from functional ankle instability were selected based on a structured interview. Talar tilt was measured using supine ankle stress roentgenographs and standing talar tilt was measured using erect ankle stress roentgenographs. A digital roentgenocinematographic analysis of a 50 degrees ankle sprain simulation was performed to measure dynamic talar tilt and inversion distance between two video images (inversion speed). A significant decrease in pathologic supine talar tilt in unstable ankles was found in the braced compared with the nonbraced situation (talar tilt = 13.1 degrees versus 4.8 degrees with brace). The talar tilt with the brace after activity was still significantly lower than the initial value without the brace. The standing talar tilt of unstable ankles was shown to be significantly lower with the orthosis than without (standing talar tilt = 16.6 degrees versus 12.0 degrees with brace). Roentgenocinematographic evaluation of ankle sprain simulation showed that the mean dynamic talar tilt during simulated sprain decreased significantly in the braced ankles compared with the nonbraced ankles (dynamic talar tilt = 9.8 degrees versus 6.4 degrees braced). A significant decrease in the digital measurement of inversion distance (from 110.6 pixels to 92.4 pixels) was observed in the total sample of 39 ankles during the initial high-speed phase of the simulated sprain. The brace significantly slows down the inversion speed.
