The role of concomitant biceps tenodesis in shoulder arthroplasty for primary osteoarthritis: results of a multicentric study.

This study evaluated the effects of concomitant biceps tenodesis in patients undergoing shoulder arthroplasty for primary osteoarthritis. Six hundred eighty-eight shoulders that had undergone replacement for primary glenohumeral arthritis were reviewed at a mean 43 months postoperatively. One hundred twenty-one patients had undergone a biceps tenodesis at arthroplasty, while the remaining patients did not. Tenodesis was significantly better than no tenodesis in most outcome parameters. No difference was found between the groups in complication rate. Biceps tenodesis is a useful adjunct to shoulder arthroplasty in the treatment of primary osteoarthritis.

[The role of the long head of the biceps in subacromial impingement syndrome and arthroscopic assisted tenodesis].

OBJECTIVES: Tenosynovitis of the long head of the biceps tendon, which commonly accompanies subacromial impingement syndrome, is one of the most important underlying cause of shoulder pain. We evaluated our experience with arthroscopic subacromial decompression and tenodesis of the long head of the biceps using mini-open approach. METHODS: Among patients who underwent arthroscopic subacromial decompression (112 patients) alone or in combination with mini-open rotator cuff repair (55 patients), 19 patients (11%; 12 females, 7 males; mean age 47 years, range 42 to 62 years) had tenodesis of the long head of the biceps. During arthroscopy of the glenohumeral joint, the decision for tenodesis was based on the presence of irreversible findings of chronic inflammation such as atrophy, excessive fraying, or partial rupture. The patients were divided into two groups depending on the surgery, namely, mini-open rotator cuff repair (group 1, 9 patients) and arthroscopic subacromial decompression alone (group 2, 10 patients). The mean follow-up was 17.6 months in group 1 (range 12 to 28 months), and 19.6 months in group 2 (range 12 to 40 months). RESULTS: Seven patients in group 1 (78%) did not complain about pain, while two patients had pain after vigorous physical activity. In group 2, nine patients (90%) were pain-free, whereas one patient had moderate pain. None of the patients had any cosmetic deformity. Two patients in group 1, and one patient in group 2 had mild biceps spasms. CONCLUSION: Despite the small sample size and a relatively short follow-up period, our results for tenodesis may be regarded as satisfactory. Special attention should be paid to the arthroscopic evaluation of the biceps tendon and tenodesis may be inevitable in the presence of chronic changes.

Lateral hindfoot instability treated with the Evans tenodesis: a biomechanical analysis.

The stabilizing effect of the Evans tenodesis on movements in the tibiotalocalcaneal joint complex was studied in 10 amputation specimens, using a kinesiologic testing device. The tenodesis was tested following solitary lesion of the anterior talofibular ligament and after combined lesions of the anterior talofibular and calcaneofibular ligaments. All tenodeses were performed with the joint complex in the neutral position. Regardless of the extent of ligamentous damage, the tenodesis frequently restricted adduction and internal rotation to a level below that recorded at intact ligaments. Instability in external rotation in the joint complex and anteroposterior laxity of the talus were never completely reconstructed, regardless of what degree of flexion in the joint complex the tenodeses were tested. The study demonstrates that, if performed with the tibiotalocalcaneal joint complex in the neutral position, the Evans tenodesis cannot reconstruct normal hindfoot kinematics, irrespective of the extent of ligamentous damage. However, severe instability in adduction and internal rotation, both part of clinical supination, were effectively prevented by the tenodesis.

Distal biceps tendon rupture: biomechanical analysis of repair strength of the Bio-Tenodesis screw versus suture anchors.

The purpose of this study was to compare the strength and stiffness of distal biceps tendon ruptures repaired with either a Bio-Tenodesis screw or suture anchor technique in a cadaveric model. Ten matched pairs of cadaveric arms underwent simulated distal biceps tendon ruptures and were repaired with either a Bio-Tenodesis screw or suture anchor technique. We analyzed pullout strength, stiffness, and mode of failure for each construct. The mean pullout strength of the repair with a Bio-Tenodesis screw was significantly higher (192 N [SD, 42.5 N] vs 147 N [SD, 29.5 N], P < .013). Use of the Bio-Tenodesis screw is an effective means of repairing distal biceps tendon ruptures. It provides significantly more initial pullout strength compared with suture anchors. This could potentially allow more aggressive rehabilitation and faster return to function.

Arthroscopic tenodesis for lesions of the long head of the biceps.

OBJECTIVE: Resection of the intraarticular part of the long head of the biceps and tenodesis to decrease shoulder pain due to a pathologically altered biceps tendon and to improve shoulder function. INDICATIONS: Tenosynovitis. State of prerupture. Instability (subluxation or dislocation of tendon from intertubercular groove). Intraarticular entrapment secondary to hypertrophy of the long head of the biceps in the presence of an intact cuff. To be performed during arthroscopic cuff repair or during debridement of an irreparable cuff tear. CONTRAINDICATIONS: Very thin, frayed, almost ruptured biceps tendon. Complete rupture of the long head of the biceps. SURGICAL TECHNIQUE: Standard arthroscopy with 30 degrees scope inserted through the posterior portal. Detachment of the long head from the glenoid origin. Longitudinal opening of the bicipital groove. Exteriorization and doubling of the tendon. Drilling of a socket starting in the groove but perforating the posterior cortex only with a guide wire. Passing of the tendon in an anteroposterior direction and securing the anchorage with a bioresorbable PLA interference screw. RESULTS: Between 1997 and 1999, an arthroscopic tenodesis was performed in 43 patients. Minimum follow-up 2 years. The absolute Constant Score improved from 43 points preoperatively to 79 points at the time of follow-up. No loss of elbow extension or flexion; power of biceps after tenodesis 90% of opposite side. Early on, two failures of tenodesis occurred.

Arthroscopic biceps tenodesis.

Arthroscopic biceps tenodesis is indicated for the treatment of severe biceps tendonopathy, partial- or full-thickness tendon tears, or biceps instability typically associated with rotator cuff tear, although there has been considerable debate on tenotomy versus tenodesis. We advocate tenodesis, for the following reasons: to re-establish the resting muscle length so as to avoid scaring and spasm, to allow biceps use for complex elbow motion, and to avoid cosmetic defects in cases in which deformity can sometimes equal disability. This technical note provides illustrations and detailed descriptions of our arthroscopic tenodesis technique using a Arthrex (Naples, FL) biotenodesis system.

Arthroscopic biceps tenodesis using interference screw: end-tunnel technique.

The conflict between tenotomy versus tenodesis for biceps lesions of the shoulder has not been resolved. We, however, believe that tenodesis is the treatment of choice until proven otherwise. Hence our department has been performing arthroscopic tenodesis for biceps subluxation or partial tears that involved over 50% of its diameters. We introduce our technique of arthroscopic biceps tenodesis in which the biceps tendon is fixed in the sequentially enlarged bony end-tunnel using bioabsorbable interference screws without transosseous drilling.

Arthroscopic biceps tenodesis.

The proximal biceps tendon is a significant source of shoulder pain that may be treated with biceps tenotomy or tenodesis. Biceps tenodesis has suggested advantages over tenotomy that include maintenance of the length-tension relationship, prevention of muscle atrophy, maintenance of elbow flexion and supination strength, avoidance of cramping pain, and avoidance of cosmetic deformity. The recent advancement of all arthroscopic tenodesis techniques has provided sufficient fixation strength while easing technical demands and minimizing neurovascular injury risk. With our newer techniques and better understanding of proximal biceps tendon pathology, the indications for tenodesis are evolving, and longer-term follow-up is required to fully evaluate the outcome of these procedures.

Principles of conservative management for a non-orthotic tenodesis grip in tetraplegics.

The effectiveness of a tenodesis grip is determined by the passive properties of the hand. An effective tenodesis grip can be achieved by encouraging a decrease in the resting length (i.e., adaptive shortening) of the flexor digitorum profundus and the flexor digitorum superficialis so that the fingers flex when the wrist is extended. Also, adaptive shortening of the flexor pollicis longus needs to be encouraged so that the thumb approximates the flexed fingers when the wrist is extended. The length of the adductor pollicis will in part dictate where along the radial side of the index finger the thumb will contact. Development of an effective tenodesis grip also requires that excessive metacarpophalangeal and interphalangeal joint stiffness of the fingers be prevented and that the interphalangeal joint of the thumb become stiff in extension. Careful management of the tetraplegic hand can ensure the development of the musculoskeletal changes necessary for an effective tenodesis grip.

[Extensor tenodesis to the retinaculum extensorum: anatomic and biomechanical study].

INTRODUCTION: The extensor tenodesis is a direct dynamic tenodesis which is activated by wrist flexion due either to hand weight or flexor carpi radialis. This tenodesis is usually performed to the distal radius, but it is possible to fix EDC (extensor digitorum communis) to the retinaculum extensorum. MATERIAL AND METHODS: Biomechanical study concerned 12 anatomical subjects (24 wrists). The biometric and radiological analysis of retinaculum displacement distalwards was made under low (1 kg) and moderate (6 kg) pulling. Surgical clips were placed on the proximal and distal limits of the retinaculum in order to study their positions on roentgenograms. RESULTS: Average width of the retinaculum was 19 mm. Average movement under 1 kg drive was 6 mm and 8.6 mm under 6 kg drive. X-rays showed that the proximal border of the retinaculum was always located proximally to the wrist rotate centre, whatever the traction. DISCUSSION: We found the same anatomical features described by different authors, except for the width of the retinaculum. Our study suggests that the retinaculum is strong enough to support a surgical tenodesis.

Arthroscopic biceps tenodesis: a new technique using bioabsorbable interference screw fixation.

PURPOSE: To report a new technique of arthroscopic biceps tenodesis using bioabsorbable interference screw fixation and the early results. TYPE OF STUDY: Prospective, nonrandomized study. METHODS TECHNIQUE: The principle of arthroscopic biceps tenodesis is simple: after biceps tenotomy, the tendon is exteriorized and doubled on a suture; the biceps tendon is then pulled into a humeral socket (7 or 8 mm x 25 mm) drilled at the top of the bicipital groove, and fixed using a bioabsorbable interference screw (8 or 9 mm x 25 mm) under arthroscopic control. PATIENTS: 43 patients treated with this technique between 1997 and 1999 were followed-up for at least 1 year. The technique was indicated in 3 clinical situations: (1) with arthroscopic cuff repair (3 cases), (2) in case of isolated pathology of the biceps tendon with an intact cuff (6 cases), and (3) as an alternative to biceps tenotomy in patients with massive, degenerative and irreparable cuff tears (34 cases). The biceps pathology was tenosynovitis (4 cases), prerupture (15 cases), subluxation (11 cases), and luxation (13 cases). RESULTS: The absolute Constant score improved from 43 points preoperatively to 79 points at review (P <.005). There was no loss of elbow movement and biceps strength was 90% of the strength of the other side. Two patients, operated on early in the series, presented with a rupture of the tenodesis. In both cases the bicipital tendon was very friable and the diameter of the screw proved to be insufficient (7 mm). No neurologic or vascular complications occurred. CONCLUSIONS: Arthroscopic biceps tenodesis using bioabsorbable screw fixation is technically possible and gives good clinical results. This technique can be used in cases of isolated pathologic biceps tendon or a cuff tear. A very thin, fragile, almost ruptured biceps tendon is the technical limit of this arthroscopic technique.

Long-term outcome of anatomical reconstruction versus tenodesis for the treatment of chronic anterolateral instability of the ankle joint: a multicenter study.

The long-term clinical outcome after anatomical reconstruction and tenodesis in the treatment of chronic anterolateral ankle instability was assessed in a retrospective multicentre study. The first group (AR) consisted of 25 patients (mean age at operation 22 yrs +/- 5.7) who underwent anatomical reconstruction and the second group (TE) of 29 patients (mean age 23 yrs +/- 6.6) who underwent tenodesis. For both groups, the mean follow-up period was 12.3 yrs (AR +/- 2.5 yrs, TE +/- 2.7 yrs). At physical examination, there were significantly more patients in the TE group (n=18) with a positive anterior drawer sign as compared with the AR group (n=7) (p=0.02). Medially located degenerative changes in the ankle joint as seen on standard radiographs were seen more often in the TE group (n=7) than in the AR group (n=1) (p=0.03). The mean talar tilt, 4.7 degrees in the AR group vs 6.9 degrees in the TE group, (p=0.02) and anterior talar translation, 2.9 mm in the AR group vs 4.3 mm in the TE group, (p=0.04) were significantly higher in the TE group at radiographic stress examination. According to the rating system developed by Good et al. (1975), significantly fewer patients in the TE group (n=8) had an excellent result as compared with the AR group (n=15) (p=0.03) and more patients in the TE group (n=9) had a fair or poor result (p=0.04) as compared with the AR group (n=2). We conclude that a tenodesis procedure does not restore the normal anatomy of the lateral ankle ligaments. When compared with anatomical reconstruction, a tenodesis leads to inferior results in terms of functional and mechanical stability, as well as overall satisfaction at long-term follow-up.

Watson-Jones tenodesis for ankle instability. A mechanical analysis in amputation specimens.

The stabilizing effect of a modified Watson-Jones ankle tenodesis was studied in 10 lower extremity amputation specimens using a kinesiologic testing device. Cutting of the lateral ligaments caused maximal instability in adduction of the entire hindfoot joint complex, as well as of the talocalcaneal joint. The tenodesis restricted adduction and internal rotation when compared with the movement pattern with intact ligaments. Instability in external rotation persisted because the tenodesis did not restore the function of the calcaneofibular ligament. Our study confirms clinical observations that the Watson-Jones ankle tenodesis prevents abnormal inversion of the hindfoot, but does not restore hindfoot kinematics.

Arthroscopic biceps tenodesis: technique and results in six dogs.

Biceps tenodesis was performed using an arthroscopic-assisted technique on six dogs diagnosed with chronic bicipital tendon pathology. The technique was performed using two different fixation methods (i.e., cannulated interference screw, cannulated screw and tissue washer). All six dogs had successful outcomes in terms of return to full function at a mean follow-up time of 11.7 months after surgery. Arthroscopic biceps tenodesis is a feasible option for surgical management of biceps tendon pathology, and it may have advantages over open tenodesis and open or arthroscopic tenotomy. Further study is needed before definitive recommendations regarding indications, complications, and prognosis associated with arthroscopic biceps tenodesis can be made.

Tenodesis for chronic lateral ankle instability.

The goal of lateral ankle stabilization is restoration and stability without any functional deficit. Obviously, only anatomic reconstruction can prevent deficits in range of motion. As a result, motion loss is unavoidable with tenodesis procedures. Unfortunately, no procedures are available for anatomic reconstruction of subtalar joint instability. Therefore, when there is objective evidence of subtalar joint instability, tenodesis procedures must be considered. The authors believe that stability is more important than range of motion when degenerative changes are present within the ankle joint. Tenodesis results are good for the short term (less than 5 years) but may deteriorate over time (after more than 9 years). Some residual pain is common following tenodesis procedures.

[Anterio-lateral extra-articular tenodesis of the knee using a short strip of fascia lata].

This study describes a lateral extra-articular tenodesis using a short strip of ilio-tibial band. The tenodesis consists of a 12 x 75 mm strip of iliotibial band remaining attached to the Gerdy's tubercle. An isometric point in the region of Krackow's point F-9 is determined with a callipers. The strip of iliotibial band is twisted by 180 degrees to enhance its isometry. Then it is either onlay with a screw and spiked washer on the F-9 point, or within a transverse tunnel drilled through the lateral femoral condyle, from the F-9 point, using and interference screw. Thus, the uses of a short ilio-tibial band tenodesis with a 180 degrees twist in combination with a BPTB reconstruction of the ACL, leads to similar results that the combined classic Lemaire tenodesis, with shorter skin incision, shorter graft harvesting, and at least on the biomechanical standpoint a better graft isometry.

[Arthroscopic assisted biceps tenodesis].

OBJECTIVES: Functional results of arthroscopic assisted biceps tenodesis were evaluated in patients with chronic biceps tendinitis. METHODS: The study included six patients (4 women, 2 men, mean age 55 years, range 47 to 60 years) who underwent arthroscopic assisted biceps tenodesis with a diagnosis of chronic biceps tendinitis. During tenodesis, the biceps tendon was secured with the use of key-hole technique in one patient, and with suture anchors in five patients. The patients were evaluated by the Constant shoulder scoring system. The mean follow-up was 12 months (range 6 to 36 months). RESULTS: All the patients had shoulder impingement syndrome, five patients had rotator cuff lesions, and one patient had os acromiale. The mean preoperative and postoperative Constant scores were 62 (range 60 to 65) and 84.2 (range 82 to 87), respectively. All patients returned to work within a mean of six weeks. No complications were observed during follow-up. CONCLUSION: Arthroscopic assisted biceps tenodesis may give successful results in patients with chronic biceps tendinitis with coexistent shoulder impingement syndrome or rotator cuff lesions.

Extensor tenodesis for plexic hands with C7 to T1 or C8, T1 root avulsions: a new technique.

In C7 to T1 or C8, T1 root avulsion palsies, restoration of finger active extension is not possible. Only tenodesis may restore hand opening in active wrist flexion. Many techniques have been described to restore this motion. In routine techniques, extensor tendons are fixed on radius or sutured on dorsal retinaculum. However, in these procedures, progressive tendon lengthening or ruptures may occur and salvage procedure may be difficult to perform. Therefore, we proposed a new extensor tenodesis technique. The extensor digitorum communis tendons are sutured on the paralyzed flexor digitorum superficialis tendons through interosseous membrane. This procedure allows performing a strong tendon to tendon suture more resistant than radius or retinaculum fixation. As other tenodesis techniques, wrist flexion has to be active to obtain hand opening.
