[Arthroscopic treatment of dorsal ganglion cyst at the wrist. About 54 cases].
INTRODUCTION: Ganglion cyst of the wrist can, some time, need surgery. Different arthroscopic technical procedures have been described. We report our experience in all articular resection of dorsal ganglion cyst of the wrist. OBJECTIVES: Evaluation of efficiency of resection of dorsal ganglion cyst of the wrist by of arthroscopic resection of the pedicle. METHODS: Fifty-four cysts of 52 patients have been evaluated retrospectively. Operative data, pain, strength, recurrence and complications have been collected. RESULTS: Average follow up was 28 months (6 to 78). Return to work was 8,8 days, operative time 41 minutes (25 to 90). In 67% cases, the operation was judged easy. Three surgeries had to be performed open. Complications were one hematoma and one neurodystrophy. Pain decrease from 3,37 to 1,76 on analogical pain scale. Flexion was 89% of opposite side, extension 88%. Sixteen recurrences (29.7%) were found. Sixty percent of those recurrences occurred during the first year experience. But independently of experience, the operative performance was foun difficult in 1 time on 3. CONCLUSION: Endoarticular arthroscopic resection of the pedicle of ganglion cyst is not so reproducible. In experimented hands, it remains a difficult procedure after a long learning curve with a recurrence rate 3 times higher from what is reported in literature for open surgery. For our discharge, our long follow-up can contain some cases of de novo cyst explaining this high rate, the learning curve is certainly the main reason for our high recurrence.

[Total knee arthroplasty for recent severe fracture of the proximal tibial epiphysis in the elderly subject].
PURPOSE OF THE STUDY: Bone comminution, serious cartilage damage, and the poor mechanical quality of osteoporotic bone create a difficult challenge for osteosynthesis of joint fractures in the elderly subject. Poor results with certain hip, elbow and shoulder fractures have lead certain authors to propose emergency arthroplasty in selected cases. We report our experience with four knee arthroplasties implanted for recent severe fracture of the proximal tibial epiphysis in elderly subjects. MATERIAL AND METHODS: Four independent patients aged over 75 years presented a severe comminutive fracture of the proximal epiphysis of the tibia (Three Schatzker 5, one Schatzker 4). After obtaining the patients' informed consent, early knee arthroplasty was performed. A long-stem cemented tibial piece was used on which the epiphysis was reconstructed. Implants providing support for ligament deficits were used in all cases. Immediate weight-bearing was authorized. RESULTS: Follow-up ranged from two to seven years. The IKS function score (15, 60, 100, 100) depended on the patient's general status. The IKS knee score was excellent for three knees (90, 95, 95), and fair in one (45). Re-operations were not needed in any of the patients. All x-rays showed bone healing with correctly aligned limbs (less than 2 degrees deformation). There were no lucent lines at last follow-up. DISCUSSION: Early arthroplasty for complex fractures of the proximal epiphysis of the tibia is a realistic option. Using a cemented long-stem tibial piece ensures primary stability sufficient for early weight-bearing before bone healing. Use of a constrained prosthesis, or better a hinged prosthesis, can be questioned but avoids the difficulty of ligament balance on an osteoporotic knee with a destroyed joint surface. None of the patients required reoperation and the results in terms of pain were excellent. The overall outcome depends on the general status of the patient.

[Pre-operative diagnosis of bucket-handle meniscal tears: clinical evaluation and value of arthroscan and MRI radiological criteria].
PURPOSE OF THE STUDY: It is important for both the patient and the surgeon to determine whether a meniscal lesion can be repaired before undertaking surgery. The purpose of this study was to examine the pertinence of clinical signs and determine the value of imaging findings for the preoperative diagnosis of bucket-handle meniscal tears. This preliminary study was conducted before undertaking an analysis of preoperative criteria of reparability in a homogeneous group of meniscal lesions. MATERIAL AND METHODS: This retrospective series included 33 arthroscopically-proven bucket-handle meniscal tears in patients who underwent arthrography and/or arthroscan and/or MRI preoperatively. The images were reviewed by two senior radiologists who established a consensus diagnosis. Clinically, the type of blockage and the presence of permanent flexion before surgery were noted. The following items were noted on the imaging results: fragment displacement (fragment in the notch on the coronal slice) anterior megahorn, double PCL, and serpent sign on the sagittal slice. Longitudinal, transversal extension and position of the bucket-handle were noted. We searched for correlations with the intraoperative findings. RESULTS: Fourteen patients had a history of knee blocking and 15 had permanent flexion before surgery. Only 10 patients had the typical association of blocking and flexion. Certain diagnosis of bucket-handle meniscal tear was provided by MRI (13/15), arthroscan (6/7), and arthrography (10/24) giving an equivalent sensitivity for the two slice imaging techniques. The sign of a fragment in the notch on the coronal slice was a constant finding. The double PCL sign was sensitive for medial meniscal tears and for lateral meniscal tears with associated ACL tears. The diagnosis was successfully established in all 9 patients who underwent several explorations (2 or 3). Buckle-handle meniscal tear was not identified in 9 patients (arthrography 7, MRI 2). DISCUSSION: Our findings demonstrate that the preoperative diagnosis of bucket-handle meniscal tears cannot be properly established on clinical criteria of typical blocking and/or permanent flexion. They confirm that arthrography is not contributive to diagnosis and that the absence of a slice image is detrimental to diagnosis. The sensitivity of the two slice imaging methods was similar. The key sign was the presence of a fragment in the notch on the coronal slice; in the three cases where this sign was absent, the reason was found to be the small size of the displaced fragment (resolution limit) and time between imaging and arthroscopy. The characteristic features of the bucket-handle lesions observed in this series are exactly the same as reported in earlier reports but to our knowledge provide the first data on comparative performance of arthroscan and MRI. CONCLUSION: The noninvasive nature of MRI and the possibility of assessing the meniscal wall and the quality of the meniscal tissue make MRI the exploration of choice for preoperative assessment of meniscal tears.

[Re-infection with a different strain after prosthesis revision for bacterial infection: 13 cases].
PURPOSE OF THE STUDY: Treatment of an infected arthroplasty is always a delicate task. Multidisciplinary management involving surgeons, clinicians, bacteriologists, and the patient may be long and not always successful. Rare re-infections caused by a bacterial strain different from the initial strain may be a cause of failure. We analyzed cases of re-infection with a different strain in search of an explanation. MATERIAL AND METHODS: We reviewed 13 cases of re-infection in 12 patients with 7 hip and 5 knee arthroplasties. The causal germ had been clearly identified by the bacteriology laboratory during the first infection. The antibiotic regimens were confirmed by the medical team. All patients underwent surgery in our unit. At the time of the second infection, the implant had been removed, had been left in place, or had been changed. We recorded the new strains isolated and studied their antibiotic susceptibility profile. Treatment protocols and biological and functional results were analyzed. RESULTS: A mean 27 months after the re-infection, clinical and biological success had been achieved in 7 cases. The failures more frequently corresponded to cases where the first infection was caused by an aggressive germ and where the second germ was found during reimplantation. DISCUSSION: Theoretically a change in the causal germ could be explained by an insufficient initial biological analysis with an unrecognized or masked germ, by peroperative contamination subsequent to the difficulties observed in these hospitalized patients, and finally by secondary contamination. We recall the criteria of secondary infection (free interval, distant infectious focus, time sequence), measures taken to prevent peroperative infections, and conditions for optimal bacteriological sampling. If no resistance emerges after the first antibiotic treatment, there could nevertheless be a selection of conditions enabling growth of germs infrequently encountered. We stress that re-infection should not be considered necessarily as a failure of initial management but can, in certain cases, be considered as a de novo infection, and treated as such.

[Reasons why musicians consult hand surgeons].
PURPOSE OF THE STUDY: Musicians occasionally consult orthopedic surgeons, particularly upper limb specialists. We wanted to learn more about the reasons why musicians attend orthopedic clinics. MATERIAL AND METHODS: We analyzed retrospectively 227 case files of musicians who consulted our center between 1994 and 2001. We noted patient related factors (age, gender, musical experience, level of performance, daily practice schedule) and their reasons for consulting (pain, discomfort, advice). We studied the medical history of the patients and searched for predisposing or triggering elements. We also recorded therapeutic options proposed. RESULTS: Our series included 119 men (52%) and 108 women, mean age 35 years with 27 years of musical experience on the average. Instruments played were mainly the piano (41%), the violin (19%), and the guitar (15%). Patients playing wind instruments, who consult more often for ENT problems, were exceptional. On the average, the patients played their instrument 4 hours daily. One-third of the patients were high-level amateurs, one-third were professionals, and one-quarter were lower-level amateurs. There was a small proportion of soloists or professors. Two-thirds of the musicians presented disorders of the musculoskeletal system, particularly trauma sequelae. Signs of overuse were present in 18% of the patients, mainly women, signs of misuse due to inappropriate or defective technique in 8.8%, and dystonia in 5.7%. Psychological problems were noted in 4 patients. More than one half of the patients had obtained medical advice prior to consulting an orthopedic surgeon and the very large majority had been referred by specialized physical therapists. A surgical procedure was proposed for only 19% of the patients presenting an orthopedic disorder. DISCUSSION: This study presents a diversified panel of musicians consulting orthopedic surgery clinics. Practicing schedules varied in the study population from one to five hours daily. More than half the patients complained of pain but 18% consulted because they perceived a problem when playing and 17% consulted simply for advice. Our findings recall that musicians comprise a sensitive population requiring careful overall management. Unlike series published to date, we had a majority of men. Problems involving an orthopedic disorder or trauma and trauma sequelae predominated. In the literature, diagnosis has been oriented by the specialty of the consulting physician. We found that our patients who suffered from overuse had often recently changed their habitual practicing methods or conditions. The diagnosis of misuse was facilitated when the patient was examined with his/her instrument. The low rate of dystonic disorders was probably related to the fact that nearly half of our patients were followed regularly by a physical therapist. We did not observe any case of excessive laxity or Linburg Comstock syndrome which exceptionally have functional impact. The very large majority of our patients were referred by physical therapists and when surgery was necessary, the procedure was performed in accordance with accepted rules concerning the therapeutic management of musicians.
