Grasping power by means of functional electrical stimulation in a case of C6 complete tetraplegia.

Grasping power (GP) by means of functional electrical stimulation (FES) was measured in a case of C6 complete tetraplegia. This was compared with GP by means of the dynamic tenodesis effect, the flexor hinge splint and the GP of normal female. Palmar grasp strength by means of FES was approximately 16% of the control group and 2.4 times greater than the flexor hinge splint. Lateral grasp strength by FES was approximately 13% of the control group. Our results suggest that FES is more effective than the flexor hinge splint in increasing the GP of tetraplegic patients, and that a stronger and stable GP, which is not affected by wrist position, makes FES practical for improving activities of daily living (ADL).

Chronic lateral instability of the ankle in athletes.

Acute lateral ligament injuries of the ankle are best treated nonsurgically, with peroneal strengthening and neuromuscular training. At least 80 to 90% of patients will regain satisfactory ankle stability after functional treatment. Chronic ankle instability occurs in approximately 10 to 20% of patients after acute ligament injuries, irrespective of primary treatment. Surgical reconstruction may be necessary, especially in athletes with high demands on ankle joint stability. Numerous different surgical procedures have been described many with some kind of a tenodesis. The classic tenodeses, Evans, Watson-Jones and Chrisman-Snook, have all been used with good short term results. Anatomical ligament reconstruction using the remnants of the ruptured and elongated ligaments, with shortening, reinsertion and duplication, have been shown to be simple, effective and free from complications. As the results of anatomical reconstruction are satisfactory both in the short and the long term, this reconstruction is recommended for correction of lateral ankle instability.

Subtalar ankle instability. A review.

The aetiology of chronic functional lateral ankle instability is fairly well understood. Pathophysiological factors such as mechanical instability, proprioceptive deficit and peroneal muscle weakness have been demonstrated. Subtalar instability has been in focus during the last years as one of the possible factors behind chronic functional instability of the foot. The exact aetiology and the true incidence of subtalar ligament injuries remain unknown. Most subtalar ligamentous injuries probably occur in combination with injuries of the talo-tibial articulation. Subtalar instability can have the characteristics of chronic lateral instability or recurrent ankle sprains. Patients with chronic subtalar instability typically complain of 'giving way' symptoms and a history of recurrent sprains. Clinical examination including increased inwards rotation and forward displacement of the calcaneus may not be sufficient for the differentiation between ankle and subtalar instability. Radiographic imaging using stress radiographs may be necessary to assess subtalar instability. Subtalar instability can be defined as chronic functional instability with increased values of talar tilt and talo-calcaneal displacement as measured with standardised stress radiographs. Few authors have addressed the treatment of subtalar instability and the condition has not been clearly defined. Subtalar instability can be treated either with a tendon transfer or tenodesis procedure, such as the Chrisman-Snook or triligamentous tenodeses, or with an anatomic ligament reconstruction using the calcaneo-fibular, lateral talo-calcaneal and cervical ligaments combined with a reinforcement of the inferior extensor retinaculum. There have been no studies comparing anatomical and non-anatomical reconstructions and the long term results after ligamentous stabilisation are unknown. The focus of this article is on subtalar instability causing chronic functional ankle instability.

Lateral instability of the ankle treated by a modified Evans procedure.

A technically simple tenodesis of the peroneus brevis tendon has been applied in the treatment of 42 patients with lateral instability of the ankle; 33 patients have been examined 2-10 years after the operation and 91 per cent showed excellent or good results. It is concluded that this procedure gives good stability in the varus as well as the antero-posterior direction and is therefore comparable to the technically more difficult Watson-Jones procedure.

Medial dislocation of the tendon of the long head of the biceps brachii.

Medial displacement of the long tendon of the biceps brachii muscle is a rare condition associated with degenerative or traumatic ruptures of the rotator cuff. This condition was recorded in nine shoulders during 45 reconstructive procedures on the rotator cuff. Five of the displacements were complete, leaving the tendon medially displaced in a fascial sling; four were incomplete, allowing a to-and-fro medial displacement of the tendon out of the intertubercular groove. Anatomical dissections on eight shoulders showed that the coracohumeral ligament is the key ligament which keeps the biceps tendon aligned in the sulcus: transection of the medial part of the ligament allows the tendon to be medially displaced. There was no pathognomonic clinical sign of the luxation or subluxation. Since abnormal movement of the tendon in the sulcus may be an important cause of shoulder pain, the condition should be carefully looked for during reconstructive procedures on the rotator cuff. Tenodesis of the displaced tendon is recommended, either as the sole procedure or in combination with other reconstructive measures.

Synovitis in chronically unstable ankles.

Histopathologic synovial changes were studied prospectively in 69 patients with 75 ankles operated on for radiographically verified chronic lateral instability. The median duration of instability was 2(0.5-20) years. Before the operation, 73 ankles were painful. After a peroneus brevis tenodesis, all but 1 patient felt improved. Twenty-eight of 75 ankles had moderate or extreme degrees of synovitis. The degree of ankle instability did not influence the severity of changes. Factors that influenced the degree of synovitis were duration of instability of more than 4 years, degenerative changes--such as old bony avulsions, chondral fibrillations and clefts--and high activity level of the patient. To improve stability, alleviate pain, and perhaps to prevent the development of arthrosis, we recommend ligamentous repair in painful active patients with long-standing lateral instability of the ankle with degenerative changes in or around the ankle joint.

Zanoli's procedure for overlapping fifth toe: retrospective study of 18 cases followed for 4-17 years.

Digitus quintus superductus pedis (overlapping fifth toe) is a congenital deformity, often bilateral, in which the fifth toe is medially directed, rotated and hyperextended. There is no consensus regarding the best treatment. We describe our experience using Zanoli's procedure, which is a tenodesis procedure using the extensor tendon of the fifth toe. Between 1979 and 1993, we operated on 16 patients (7 bilateral, total 23 feet). 13 (10 women) patients (18 feet), with a mean age of 26 (19-40) years, were seen on follow-up. The mean follow-up time was 8 (4-17) years. Pain relief was achieved in all patients. From the surgeon's point of view, 3 toes overcorrected due to technical errors were considered unsatisfactory. All patients, however, were satisfied with the result and would advise other patients to undergo the same operation.

Tendon transfers in traumatic foot.

A clinical review was performed of 11 cases of traumatic foot treated by tendon transfer. Among 11 patients, there were eight males and three females, ranging from four to 36 years of age. The anterior tibial tendon was used in six cases for tendon transfer and among these, split anterior tibial tendon was used in three cases in children. The posterior tibial tenodn was used in two cases and the extensor digitorum longus tendon of the foot was in three cases. In six cases of soft tissue injury where tendon transfer was impossible, microvascular free cutaneous flap transplantation was combined with the tendon transfer. Follow-up results were obtained from 25 months to nine years. Excellent results were obtained in eight cases and satisfactory results in three cases. For the correction of function loss in traumatic foot, tendon transfere were a useful method for the recovery of active motion of the foot. For the restoration of function loss in the traumatic foot, there are several methods of treatment such as tendon transfer, arthrodesis and tenodesis, but for recovery of the active motion of the foot, tendon transer is the only useful method.

Dynamic post-surgical hallux varus after lateral sesamoidectomy: treatment and prevention.

Hallux varus and clawing are occasionally seen after a McBride procedure, due to the severance of the flexor hallucis brevis, when the lateral sesamoid is removed. The present study includes six patients, (involving ten feet), who developed hallux varus and great toe clawing after McBride procedures were performed by various orthopedic surgeons. Treatment utilized partial proximal phalangeal resection, with and without silicone single-stem implants, extensor hallucis longus tendon transfer to the great toe metatarsal, and interphalangeal joint arthrodesis, or tenodesis of the great toe to correct clawing. One patient eventually required a great toe metatarsophalangeal joint fusion. This reconstructive surgery is generally effective by correcting capsular malalignment, the "bowstringing" tendency of the extensor hallucis longus, and great toe clawing that develops simultaneously with hallux varus. Lateral sesamoidectomy is risky, and believed unnecessary as adductor hallucis tenotomy is effective in relieving hallux valgus. Although, it can occur with excessive excision of the medial emminence and distal advancement of the abductor hallucis. The author is unaware of hallux varus developing after adductor hallucis tenotomies.

Operative management of acute PCL injuries with associated pathology: long-term results.

Eighteen consecutive patients with posterior cruciate ligament injury and associated pathology were reviewed. All were re-examined with an average follow up of 5.4 years (range: 3.5 to 7.5). Six posterior cruciate ligaments were repaired to the femur with multiple #2 nonabsorbable suture, and one "mop end" mid-substance tear was repaired with sutures in each stump. Seven mid-substance tears were repaired and augmented with the semitendinosus tendon, while four additional mid-substance tears were repaired and augmented with the semitendinosus tendon and a Dacron stent (Meadox). One medial meniscus was repaired and one was partially excised, and one lateral meniscus tear was partially excised. The anterior cruciate ligament was repaired to the tibia in two knees, left alone (interstitial tear) in two, and excised with extraarticular iliotibial band tenodesis augmentation in five. At follow up, arthrometer readings (Stryker) correlated well with clinical examination. The four knees with Dacron stent had a 0 to 1 mm difference at 90 degrees, while the failures had greater than 5 to 6 mm. Six of these were in the repair alone group and two were in the repair with semitendinosus augmentation group. Eight knees (44.5%) had radiographic changes primarily in the medial compartment. Using Hughston's perimeters to evaluate the results, objective 55.5% were rated good, 27.8% were rated fair, and 16.7% were rated poor or failures. Using Clancy's criteria, 22.2% were excellent, 22.2% were good, 44.5% were fair, and 11.1% were rated failures.(ABSTRACT TRUNCATED AT 250 WORDS)

Basal joint arthroplasty using the Roosevelt Hospital techniques.

Many reconstructive procedures have been developed to treat osteoarthritis of the basal joint of the thumb. The current article describes techniques used at the Hand Surgery Center at Roosevelt Hospital in New York City. A tonometry applanation radiographic staging system is outlined; it serves as a rationale for selecting which form of arthroplasty is appropriate for a particular patient and is predicated on the extent of involvement of the trapezial articulations. Stage 1 disease implies symptomatic laxity of the trapeziometacarpal joint with normal articular surfaces and is most appropriately treated with volar ligament reconstruction. Stage 2 is an intermediate category and amenable to either volar ligament reconstruction or interpositional arthroplasty of the trapeziometacarpal joint, based on the condition of the articular cartilage at surgery. In stage 3 disease there are significant degenerative changes of the trapeziometacarpal joint with preservation of the articular surfaces of the scaphotrapezial joint. Two variations on ligament reconstruction with interpositional arthroplasty of the trapeziometacarpal joint are described; they have consistently good results. Finally, stage 4 is characterized by pantrapezial degenerative disease and necessitates trapezial resection. Reconstruction may be by silicone rubber implant arthroplasty using a stemmed trapezial implant stabilized by an abductor pollicis longus tenodesis. The alternative is a procedure in which the thumb metacarpal is tethered to the index metacarpal by a ligament reconstruction.

The Cobb procedure for stage II posterior tibial tendon dysfunction.

Flexor digitorum longus transfer or augmentation is currently the most popular adjunctive procedure for the repair of an attenuated or ruptured tibialis posterior tendon. Although the procedure is efficacious, an important functional muscle is sacrificed. Results show that similar results can be achieved with a tenodesis procedure by way of a split anterior tibial tendon repair. The authors have modified the Cobb procedure, and do not create a hole through the medial cuneiform or navicular. The thick, fibrous periosteal tissue at the medial aspect of the cuneiform is a sufficient tunnel for securing and positioning the tibialis anterior tendon. An additional site of healing and potential complications are avoided. The Cobb procedure is a useful and successful treatment option for PTTD, provides strong autograft augmentation to the posterior tibial tendon without sacrificing function of other tendons, and offers the surgeon and patient predictable outcomes with long-term satisfaction.

[Anatomic reconstruction of the lateral ligaments of the ankle using a plantaris tendon graft in the treatment of chronic ankle joint instability].

The purpose of this work was to present our technique of anatomic reconstruction of the lateral ankle ligaments using a free plantaris tendon graft. Between 1988 and 1997, 52 ankles (48 patients) were treated for chronic ankle instability resisting to a training program of minimally 3 months. The average age was 28.6 years (16 to 46 years) at the time of surgery. There were 30 ankles in men and 22 ankles in females. 4 patients were treated on both ankles. 50 ankles were available for a follow-up investigation after a mean of 3.5 years (1 to 10 years). Based on the AOFAS-Hindfoot-Scale an average score of 97.9 points (90 to 100 points) was found. The functional result was found to be excellent in 39 ankles (78 %), good in 9 ankles (18 %), fair in 2 ankles (4 %), and poor in 0 ankle (0 %). Dorsi-/plantarflexion was not restricted in any ankle. Supination was slightly restricted in 2 ankles, but not increased in any ankle. High patient's satisfaction with respect to the achieved stability was found in all but one ankle. No deterioration with time was observed in any case. The overall good and excellent results with this method may be explained by the strictly anatomic reconstruction that did not alter the kinematics nor the mechanics of the ankle joint complex. In addition the peroneal tendons were not weakened. We feel that this procedure is a better alternative to other more complex ligament reconstructions, especially tenodesis operations by using the peroneal tendon.

Salvage of failed resection of the distal ulna. Case report.

A 45-year-old woman completely lost the ability of active supination of the forearm after a Darrach resection for malunited fracture of the distal radius. A three-component reconstruction was performed to stabilise the distal stump of the ulna and prevent convergence between the two forearm bones. The procedure combined advancement lengthening osteotomy of the ulna, longitudinal intramedullary tenodesis of the extensor carpi ulnaris tendon, and dorsal transfer of the pronator quadratus through the interosseous space. Four months after the salvage procedure she again had full active supination of the forearm and she returned to work two months later.

[Evaluation of the function of the flexor and extensor tendons of the hand].

Evaluation of the function of flexor tendons is a complex problem with a lot of controversies. Many propositions have been done since the first quotation of Boyes in 1950. Were are making a presentation and a critical analysis of the most used methods: T.A.M., Kleinert's classification, and the one described by Buck-Gramcko. We are presenting a personal method, useful in every zone, eliminating the action of the intrinsics and showing certain tenodesis effects. This method has been compared to those of Kleinert, Buck Gramcko and Strickland, using the analysis of the results of 165 tendon sutures. Our results are situated in between the most optimistic method (Buck-Gramcko) and the most severe method (Strickland). Moreover, the authors propose an original method of evaluation of the extensor tendon function extrapolated from the one used for the flexor tendons.

Repair of distal biceps brachii tendon ruptures.

This study consisted of 26 male patients with distal biceps tendon ruptures, 2 of whom had bilateral injuries, making the total number of ruptures 28. The average age at injury was 45 years. The treatment groups were the following: 3 were treated without surgery, 4 were repaired with brachialis tenodesis, and 21 were reattached to the radial tuberosity by the 2-incision Boyd-Anderson approach. Patients underwent follow-up a minimum of 14 months after surgery, with the average being 43 months. Outcome was evaluated based on the physical examination, isokinetic testing of strength and endurance of flexion and supination, and radiographic analysis.

Surgical treatment of chronic dislocation of the sterno-clavicular joint.

The costo-clavicular ligament is always ruptured in dislocation at the sterno-clavicular joint. Anterior, superior or posterior displacement of the medial end of the clavicle may occur. Acute dislocation usually responds to conservative treatment and operation is seldom required. Chronic, or recurrent, dislocation may cause pain and disability on strenuous activity and necessitate surgical treatment. The operation of tenodesis of the subclavius tendon with capsulorrhaphy described by Burrows (1951) has been adopted. The intraarticular meniscus is often damaged and displaced, and may block reduction; its removal is then necessary. In addition, a threaded Stinmann pin transfixing the joint has been found useful to maintain the stability of reduction. The operation has been performed on five patients, four of whom had excellent results. The fifth patient disrupted the repair in a drinking bout shortly after the operation.

Orthotics research evaluation framework.

The evaluation framework presented here defines a three-tier hierarchy of the functional goals of rehabilitation, using the tenodesis splint as an example of an orthosis designed to improve limb function. These goals are combined with five categories of evaluative criteria to create a matrix. Based upon the key validity assumptions underlying the goals, conjoint criteria are suggested. Directions of development and inquiry are indicated. The matrix illustrates the separation as well as the integration of goal levels and evaluative categories; it sets the stage for the proper context and relative importance of specific splinting. This framework will increase the validity of criteria for orthotics evaluation in the design of future clinical studies.
