The four-in-one arthroplasty for the painful arc syndrome.

The painful arc syndrome of the shoulder is a manifestation of rotator cuff tendinitis associated with tenosynovitis of the long head of the biceps under and just distal to the transverse humeral ligament. Eighty-nine patients with clinical signs of the painful arc syndrome were proven to have an associated biceps tenosynovitis by arthrography and at surgical treatment. The four-in-one arthroplasty consists of: (1) excision of the coracoacromial ligament; (2) acromioclavicular arthroplasty; (3) excision of the anterior inferior area of the acromion process; and (4) transfer and tenodesis of the long head of the biceps. The operation decompresses the acromial arch and also eliminates the biceps tenosynovitis by tenodesis. Almost invariably, there was relief of pain within four to five months of postoperative rehabilitation, and at an average follow-up of two to eight years.

[Reoperation after surgery of flexor tendons].

After stabilizing operations such as tenodesis or arthrodesis used for lesions of flexor tendons in the hand, secondary operations to achieve more suitable angulation are mainly needed when there is elongation of the tenodesis. Complications are more frequent after mobilizing operations such as reinsertion, advancement, Z-lengthening, primary suture, tendon graft or tendon transfer. Tenolysis, the operation most frequently used, since contractures may occur after all the prementioned procedures, is treated in a separate paper. Tendon rupture, for instance after reinsertion or advancement operations may require repetition of the primary procedure. More often another procedure will be indicated, for instance a graft after rupture of a primary suture. Pulley reconstruction is necessary when correction of bow-stringing is the aim. Synovitis after the first stage of HUNTER's tenoplasty, a consequence of mechanical or chemical irritation from the silastic rod, is best treated by a short period of immobilisation. Tardy, secondary contractures after tendon graft are a real problem. If conservative treatment using splints is ineffective, either the hook-deformity has to be accepted or the finger amputated.

[Isolated intraarticular plasty of the semitendinosus or combined intra- and extra-articular plasty in chronic anterior laxity of the knee].

MATERIAL AND METHODS: In a prospective study we examined 32 athletes with arthroscopic implantation of a double loop of semitendinosus tendon for intra-articular anterior cruciate ligament reconstruction combined with an iliotibial band tenodesis for extra-articular augmentation. They were compared to 26 athletes operated by isolated intra-articular semitendinosus reconstruction. RESULTS: The Lysholm-Score, clinical and radiological findings, KT-1000 stability values and isokinetic tests were evaluated monthly over a year. The data suggests that while both procedures under standardized rehabilitation conditions may obtain excellent functional results, adding the iliotibial band tenodesis to an intra-articular reconstruction significantly improves stability and muscular strength. Patients were able to resume all activities without a pivot shift following combined intra- and extra-articular stabilization.

Results of Watson-Jones ankle reconstruction for instability. The influence of articular damage.

We reviewed 32 ankles in 30 patients at an average of five years after a Watson-Jones tenodesis. All but one patient had had ankle pain before operation and 19 had had clicking, catching, or locking of the ankle. Eleven of these had an ankle arthrotomy at the time of ligament reconstruction for intraarticular pathology. At review seven of 23 ankles had a significant decrease in ankle motion, and five in subtalar motion, but only two were unstable on examination. Twenty-one ankles, however, caused some pain on activity and nine were tender on palpation. These findings indicate intra-articular degeneration or injury rather than simple instability. Radiographs of 16 ankles showed good varus and anterior-drawer stability. Seven had talocrural osteoarthritis, but only four showed grade-1 subtalar osteoarthritis. We found no correlation between follow-up time and long-term results. The Watson-Jones tenodesis provides good rotational and lateral ankle instability and does not appear to lead to subtalar degeneration.

[Suture of the anterior cruciate ligament--what is the real value of this method?].

After suture of the anterior cruciate ligament without anatomical augmentation, used as a routine method, 88 patients were followed up after a minimum of 2 years using the Lysholm score and the activity scale. Residual laxity was checked clinically and with the KT-1000. For comparison, 20 patients with chronic symptomatic anterolateral instability were followed up who had been operated on using the Eriksson technique during the same time period. Postoperative treatment was a limited functional approach. The peripheral ligament structures were treated following the Hughston and Müller principles. In two-thirds of the knees lateral tenodesis was added. The results of the suture method were disappointing and inferior to the results obtained by the Eriksson technique (trend). The Lysholm score was 77 and 82, respectively. The activity scale was 4.4 (recreational sports) for both groups. The Lachmann sign (KT-1000) in side-to-side comparison (89 N) showed a residual laxity of 1.9 mm and 0.8 mm (average), respectively. In no series was tractopexy of demonstrable advantage. The final conclusion must be that the suture method (with iliotibial tract tenodesis) is not superior to guided conservative treatment. Despite an unfavorable situation preoperatively, the (abandoned) technique of ligament substitution is superior to the suture method (trend). In isokinetic testing dominant knees fare better. In good results, a high hamstrings-quadriceps ratio is typical. The reasons for this are not well-trained hamstrings, but the relative insufficiency of the quadriceps mechanism.

[Principles of palliative motor surgery of paralysis of the hand].

The purpose of surgical restoration of the paralysed hand is to use or to reconstruct the physiological tenodesis effects which are linked on to flexion-extension motions of the wrist. Active movements of interphalangeal (IP) flexion and metacarpo-phalangeal (MP) extension of the fingers are made by extrinsic muscles coming from the forearm. The intrinsic muscles of the fingers produce MP flexion and IP extension. A claw deformity occurs when they are completely paralysed in a finger whose joints are flexible, and whose extrinsic muscles remains functional or are restored. When Bouvier's maneuver is positive, the claw is said simple, and its treatment is either MP capsuloplasty when there is no motors, or an active palliative procedure with proximal (or MP) effect when motors exist: lasso and/or direct interosseous activation. Indications of the classical active palliative procedures with distal (or IP) effect remain rare, only in a few complicated claw deformities. Circumduction of the thumb may be decomposed into three elementary movements: reposition, antepulsion, and adduction, which are respectively controlled by the radial, median, and ulnar nerves. Each of these movements may be restored by a specific tendinous transfer. In the total paralysis of the thumb as we observe in high tetraplegia, a key-grip may be restored by joint stabilization of the thumb, associated with activation of the Flexor Pollicis Longus and Extensor Pollicis Longus by means of tenodesis or tendinous transfers.

Evaluation and treatment of biceps tendon pathology.

Until recently, the role of the long head of the biceps tendon as a source of shoulder pain had been controversial. With careful examination, improved imaging techniques, and arthroscopy, a specific diagnosis can be made. In 95% of patients, biceps tendinitis is secondary to a primary diagnosis of impingement syndrome. Subluxation of the biceps tendon and primary biceps tendinitis are diagnoses of exclusion. However, in the properly selected patient, both respond well to biceps tenodesis. Rupture of the long head of the biceps tendon can be the end result of any of these pathologic processes. In the older sedate patient, conservative treatment results in little functional loss and a mild cosmetic deformity. In the young active patient, especially those who perform tasks that require supination strength, a primary biceps tenodesis should be performed, as well as decompression if there is any evidence of impingement. The key to successful treatment of lesions of the long head of the biceps tendon is recognition of associated pathologic findings in the shoulder. With advances in arthroscopy, the orthopedist can tailor treatment exactly to the pathology, minimizing morbidity and maximizing a successful outcome.

[Isolated rupture of the tendon of the supra spinatus muscle. Results of 49 surgical repair].

PURPOSE OF THE STUDY: The purpose of this study was to assess the results of surgical repairs in 49 << isolated >> tears of the supra- spinatus in 49 patients, 32 males and 17 females. MATERIAL AND METHODS: The average age at operation was 54,2 years (35 to 72) and the dominant side was injured in 30 patients (12 opposite side and 5 unknown). According to Constant's score the pain was permanent in 23 patients, it occurred at moderate exertion in 21 patients and at important exertion in 5. The average pain duration was 43,4 months (0 to 360 months). The range of motion was normal (40 points) in 24 patients, diminished in 15 (30 points), very diminished (10 points) in 7 and the shoulder was stiff in one patient (2 files were uncomplete). All the patients were disturbed in daily living activity and the strength assessment was disturbed because of the pain. In all cases we performed an anterior acromioplasty. At operation, 39 patients had an isolated tear of the supra-spinatus and 10 an associated tear of the long head of the biceps (7 tendinities, 1 dislocation and 2 ruptures). The size of the rupture was less than 2 cm2 in 21 cases comprised between 2 and 5 cm2 in 27 and greater than 5 cm2 in one case. The surgical procedure was a Neviaser's technique in 4 cases, a single suture in 19, a transosseous suture in 19 and a deltoid muscular flap in 7 cases (large retracted tear), in addition we performed 14 resections of the distal end of the clavicle and 4 tenodesis of the long head of the biceps. RESULTS: The results were assessed according to Constant's score on 46 patients (3 lost to follow-up), the average follow-up was 31,5 months (12 to 86). The average scores were: pain 12,3 points (3 to 15), range of motion 35,5 (14 to 40), daily living activity 17,4 (8 to 20), and strength 11,4 (< > side = 14,8 points). The total Constant's scores were 75,7 per cent (actual score) and 88,3 per cent (weighted score), according to the weighted score 24 patients had 100 per cent; 9 were comprized between 85 and 100, 5 between 65 and 85, and 8 were less than 65 per cent. The average post-operative acromio-humeral height was 9,84 mm (pre-operative height = 11 mm). DISCUSSION - CONCLUSION: If we compare the results in terms of surgical procedure the difference was not statistically significant although the transosseous suture was not so good: single suture 91,5 per cent, deltoid muscular flap 90,9 per cent, Neviaser's technique 87 per cent, and transosseous suture 79,1 per cent. Nevertheless the results are not so good (p = 0,01) if it is an industrial injury and if the post operative acromio-humeral height is diminished. On the other hand, age, sex, duration of the pain, occupation, tenodesis of the long head of the biceps and resection of the distal end of the clavicle don't have any pejorative influence on the results.

Spontaneous patella dislocation in Rubinstein Taybi Syndrome.

A patient with Rubinstein Taybi Syndrome ( RTS) was found to have spontaneous patella dislocation and spontaneous patella reduction. Clinical examination revealed ligamentous laxity and reducible patella. Open reduction and stabilization with semitendinosus tenodesis were done. Surgical treatment should not be put off because of the delay in the ability to walk in addition to the poor psychomotor abilities of children with RTS. This case is of particular interest as it represents an unusual type of dislocation that has not been reported in the literature so far.

Interventions for treating chronic ankle instability.

BACKGROUND: Chronic lateral ankle instability occurs in 10% to 20% of people after an acute ankle sprain. The initial form of treatment is conservative but if this fails and ligament laxity is present, surgical intervention is considered. OBJECTIVES: To compare different treatments, both conservative and surgical, for chronic lateral ankle instability. SEARCH STRATEGY: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialized Register (to July 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2005, Issue 3), and MEDLINE (1966 to April 2006), EMBASE (1980 to April 2006), CINAHL (1982 to April 2006) and reference lists of articles. SELECTION CRITERIA: All randomised and quasi-randomised controlled trials of interventions for chronic lateral ankle instability were included. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed methodological quality and extracted data. Where appropriate, results of comparable studies were pooled. MAIN RESULTS: Seven randomised trials were included and divided into three groups: surgical interventions; rehabilitation programs after surgical interventions; and conservative interventions. None of the studies were methodologically flawless. Only one study described an adequate randomisation procedure. Only two studies, both about rehabilitation programs after surgery, had a moderate risk of bias; all other studies had a high risk of bias. Due to clinical and methodological diversity, extensive pooling of the data was not possible. Surgical interventions (four studies): one study showed more complications after the Chrisman-Snook procedure compared to an anatomical reconstruction, whereas another study showed greater mean talar tilt after an anatomical reconstruction. Subjective instability and hindfoot inversion was greater after a dynamic than after a static tenodesis in a third study. The fourth study showed that the operating time for anatomical reconstructions was shorter for the reinsertion technique than for the imbrication method. Rehabilitation after surgical interventions (two studies): both studies provided evidence that early functional mobilization leads to an earlier return to work and sports than immobilisation. Conservative interventions: the only study in this group showed better proprioception and functional outcome with the bi-directional than with the uni-directional pedal technique on a cyclo-ergometer. AUTHORS' CONCLUSIONS: In view of the low quality methodology of almost all the studies, this review does not provide sufficient evidence to support any specific surgical or conservative intervention for chronic ankle instability. However, after surgical reconstruction, early functional rehabilitation was shown to be superior to six weeks immobilisation regarding time to return to work and sports.

Ligament length relationships in the moving knee.

This article presents an investigation of potential ligament attachment sites for surgical reconstruction of the anterior and posterior cruciate ligaments as well as for the lateral extraarticular iliotibial band tenodesis. Our methodology was based on quantitative measurements of knee anatomy and motion in fresh cadavers, not on biomechanical modeling. Using computer search techniques, we located all the ligament insertion sites that were nearly isometric for motion of the intact knee.

Brachial plexus surgery: our concept of the last twelve years.

In patients with brachial plexus injuries restoration of complete function is seldom seen. The diagnosis is a clinical one; investigations such as MRI or myelography are not sufficiently reliable to base surgical indications on them. Surgery has to be performed within the first six months after the trauma. The surgical procedure firstly includes an exact intraoperative definition of the extent of the lesion. Depending on the type of the lesion, microsurgical neurolysis, nerve grafting, or reneurotization is performed. When regeneration is complete, secondary operations may follow if necessary as part of our integrated concept. The spectrum of secondary operations in our patients includes arthrodesis, tenodesis, tendon transfers, muscle transfers, and free neurovascular tissue transfer. In selected cases with extensive lesions a bifunctional latissimus dorsi transfer allows restoration of minimal grip with simultaneous elbow flexion. Our concept includes a series of hierarchical steps: 1. Diagnosis and indication 2. Nerve repair 3. Intensive physiotherapy, control in intervals 4. Secondary operations--if necessary 5. Intensive physiotherapy 6. Ergotherapy, orthosis In the last 12 years 362 patients with brachial plexus lesions have been operated on in our clinic. In these patients we performed 104 neurolyses, 126 nerve grafting procedures, 87 reneurotizations, and 191 secondary operations in 96 patients. Only the combination of nerve repair with both conventional and newer methods of tendon and muscle transfers can restore the maximum function for the individual situation.

Secondary surgery following brachial plexus injuries.

The favourable treatment of post-traumatic brachial plexus lesions based on our experience of 362 cases over a 12 year period is reported. Twenty-five percent of the patients needed secondary operations. The spectrum of the latter consisted of arthrodesis, tenodesis, and musculotendinous transfer, including free neurovascular tissue transfer partially innervated by nerve transposition. Functionally, secondary tendon transfer can help to improve the effect of nerve repair techniques. To restore shoulder function the trapezius transfer (n = 22) has been used mainly; elbow flexion has been regained by pedicled latissimus dorsi translocation (n = 22), triceps-to-biceps transfer (n = 18), bipolar latissimus muscle transfer, and free neurovascular tissue transfer (n = 8). The Steindler flexorplasty was performed in four plexopathies, and finally a pedicled serratus muscle transfer was used. A unipolar latissimus dorsi transfer results in an ability to lift 10-15 kg, whilst the bipolar latissimus transfer and the triceps-to-biceps transfer produced a maximal strength of 5-8 kg. Epitrochlear flexor-pronator mass transfer produced a strength of 2-5 kg, whereas free neurovascular latissimus dorsi transfer developed a maximal muscular strength of 2-4 kg in the unipolar variation and 1-2 kg for the bipolar LD. In 97 secondary procedures to the lower arm and hand the following secondary operations were indicated: in 29 cases of radial nerve palsy transfers according to Merle d'Aubigne, a further 21 wrist tenodeses and 8 wrist arthrodeses were performed. To restore median nerve function, coupling tendon transfer (n = 4) and free neurovascular gracilis transfer (n = 3) were selected.(ABSTRACT TRUNCATED AT 250 WORDS)

Replacement of the anterior cruciate ligament. a comparative study of four different methods of reconstruction.

Eighty-seven patients have been examined 2 years on average after knee ligament reconstruction for a torn anterior cruciate ligament. The patients were divided into four groups according to the type of operation that had been carried out. In the first group an extra-articular lateral repair ("MacIntosh tenodesis") had been performed, in the second group an intra-articular "over-the-top" repair using the quadriceps and the patellar tendon, in the third group a modified "Eriksson" procedure using the patellar tendon, and in the fourth group a combined intra- and extra-articular repair using carbon fibres as a graft. The results of the operations in the different groups are compared. The best results were obtained with the "Eriksson" procedure, closely followed by the "over-the-top" repair. Limited range of motion and retropatellar pain resulting from changes in the alignment of the patella were the main problems. The results after the use of carbon fibres were less good. In two cases the graft tore without further trauma, and there were also problems because of restricted range of motion and retropatellar pain. The worst results were found after extra-articular lateral repair, due to insufficient stability in many cases. However, the best results with regard to the range of motion were found in this group.

[Arthroscopic surgical measures in the shoulder joint].

Arthroscopic and open surgery have to be combined for successful surgical therapy of the shoulder joint. A surgeon performing open surgery alone or just using arthroscopic measures cannot cover the full spectrum of modern shoulder surgery. Isolated diagnostic arthroscopy is rarely indicated. Far more common, diagnostic arthroscopy is combined with an operative procedure both to confirm preoperative assessment of pathology and to uncover associated lesions. The results of arthroscopic stabilization of chronic anterior post-traumatic dislocations fail to compare with the high success rates of open procedures. Better patient selection will probably be the key to improving results. In cases of acute traumatic first-time dislocation in young, highly athletic people, arthroscopic repair of the isolated Bankart-Perthes lesion offers the attractive advantage of anatomic reconstruction with minimal soft-tissue dissection. Further indications for arthroscopic measurements of pathologies of the glenohumeral joint are synovectomy in rheumatoid arthritis, capsulotomy in frozen shoulder and tenodesis for lesions of the long head of the biceps. Arthroscopic subacromial decompression according to Ellman is the procedure performed most often and most successfully in the shoulder joint and has overcome the classic Neer open acromioplasty. For smaller tears of the supraspinatus tendon, arthroscopic acromioplasty can be combined with an all arthroscopic suture repair or with mini-open repair. Larger tears of the rotator cuff are still the domain for open reconstructive procedures. In associated or isolated AC joint arthritis, an arthroscopic Mumford procedure can be performed. For chronic calcific tendinitis, isolated arthroscopic excision of the calcium deposit is of great value. Additionally, acromioplasty is needed for true mechanical obstruction of the subacromial space.

[Dynamic radioulnar convergence after Darrach operation, soft tissue stabilizing operations of the distal ulna and ulnar head prosthesis implantation--an experimental biomechanical study].

The most common method of treating the arthrotic distal radioulnar joint (DRUJ) is resection of the entire ulnar head (Darrach procedure). Complications related to instability of the distal forearm resulting from loss of the ulnar head are usually manifested by pain and weak grip strength and have remained the drawbacks of this procedure. In an attempt to mechanically stabilize the distal forearm, an endoprosthesis was developed to replace the ulnar head after Darrach resection. The purpose of this study was to: 1) evaluate the dynamic effects of the Darrach procedure on radioulnar convergence; and 2) evaluate the mechanical efficacy of two soft tissue stabilizing techniques (Pronator quadratus advancement flap and ECU/FCU tenodesis) for the unstable distal ulnar stump and 3) the stability after the implantation of an ulnar head endoprosthesis following a Darrach resection on radioulnar convergence. With a dynamic PC-controled forearm simulator the rotation of 7 fresh-frozen cadaver upper extremities was actively and passively performed while loading relevant muscles. Resultant total forearm torque and the 3-dimensional kinematics of the ulna, radius and third metacarpal were recorded simultaneously. The implantation of the ulnar head endoprosthesis effectively restored the stability of the DRUJ. There were significantly better results after the implantation of the prosthesis compared with the Darrach and the soft tissue stabilization procedures. This study provides laboratory validity to the option of implanting an ulnar head endoprosthesis as an attempt to stabilize the distal forearm after Darrach resection in lieu of performing soft tissue stabilization techniques.

[Proximal and distal ruptures of the biceps brachii tendon].

Proximal ruptures. Ruptures of the long head of the M. biceps humeri are commonly caused by degenerative changes within the tendon. Non-operative treatment gives good results, the loss of power regarding elbow flexion and supination amounts to only 8-21%. Refixation may be indicated for cosmetic reasons and offers a small but evident improvement of flexion and supination power. Deformity of the slipped muscle can be corrected effectively. Residual complaints after conservative treatment often result from associated subacromial problems. Distal ruptures. Ruptures of the distal tendon should be treated operatively. The loss of power after conservative treatment is evident (30-40% for flexion, >50% for supination). Extra-anatomical tenodesis to the brachialis muscle or anatomical fixation to the radial tuberosity can be applied. Flexion power and cosmesis can be addressed by both techniques. If supination strength is to be restored, the tendon has to be fixed anatomically. Preparation of the tuberosity bears the risk of heterotopic ossification or nerve damage. Mini-open techniques, using only a limited anterior approach, may decrease risks.
