Adenocarcinoma of the cervix

Sixteen ruptured extensor tendons were repaired in seven rheumatoid hands using autogenous palmaris longus tendon as a free interposition graft. The patients were reviewed at an average of 17 months (range, 5-45) after repair. Subjectively all patients were satisfied with the clinical results, and achieved a return to their level of ability before tendon rupture. A biomechanical model suggests that tendon repair using an interposition graft, rather than a traditional end-to-side tendon transfer retains the anatomical axis of tendon function, and achieves greater forces during active finger extension.     

Early motion after repair of Achilles tendon ruptures

The purpose of this study was to evaluate the clinical outcome of patients treated with limited immobilization and early motion after repair of acute Achilles tendon ruptures. Thirteen consecutive patients with complete ruptures of the Achilles tendon were identified, repaired, and rehabilitated with early motion starting an average of 10 days after surgery. Active range of motion was begun at an average of 23 days and weightbearing in a walking boot was started at an average of 3.5 weeks after surgery. The average length of follow-up was 27 months. Twelve of 13 patients returned to running activities in an average of 3 months. All 12 patients who participated in lateral motion activities before their injury returned to similar activities in an average of 7 months. The patients rated their overall status at an average of 93% of their preinjury level. Follow-up Cybex testing demonstrated plantarflexion strength averaging 92%, plantarflexion power averaging 88%, and plantarflexion endurance averaging 88% of the nonindexed extremity. Early range of motion after Achilles repair is safe and there is no increased risk of rerupture in compliant patients. The patients achieved good return of plantarflexion strength, power, and endurance.     

Deformity of the foot following anterior transfer of the posterior tibial tendon and lengthening of the Achilles tendon for spastic equinovarus

Twenty-four children with spastic equinovarus deformity due to cerebral palsy were treated by anterior transfer of the posterior tibial tendon and Achilles tendon lengthening. In five patients, the operation was performed on both sides, making a total of 29 feet available for evaluation after an average follow-up of five years. Only 38 per cent of the results were graded "good" or "satisfactory." Sixty-two per cent were rated as "poor" because of valgus, calcaneus or equinus deformity severe enough to require re-operation. The post-operative deformity was generally evident one or more years after surgery, often progressive, and more disabling as well as more difficult to correct than the original condition. Although the percentage of acceptable results was considerably higher for hemiplegic patients than for others in the study, we conclude that in this group and in all other categories of spastic patients anterior transfer of the posterior tibial tendon should not be performed.     

Neurokinin receptor mRNA localization in human midbrain dopamine neurons

The results of revision elbow arthroplasty with use of the semiconstrained Mayo-modified Coonrad implant in forty-one patients were reviewed retrospectively. The average duration of follow-up was six years (range, two to thirteen years). At the time of the latest follow-up evaluation, thirty-eight patients were able to perform activities of daily living, one had a stiff elbow because of heterotopic ossification, one had weakness secondary to an injury of the radial nerve, and one had an unstable elbow after removal of the prosthesis because of recurrent aseptic loosening. Fourteen patients sustained either a fracture or a perforation of the cortex at the time of removal of the primary implant. Three of these patients had an injury of the radial nerve; the injury was due to extravasation of the cement from a cortical defect in two of them and was sustained during removal of the cement in one. Eight patients had an intraoperative or postoperative complication that necessitated additional operative intervention. Postoperatively, twenty-two patients had complete relief of pain and sixteen had mild discomfort. Three patients remained disabled: one, because of pain secondary to loosening of the component; one, because of a pre-existing nerve injury; and one, because of the residual effects of an intraoperative injury of the radial nerve. The average Mayo elbow performance score was 87 +/- 16 points at the latest follow-up evaluation, compared with 44 +/- 17 points preoperatively (p < 0.0001). Revision elbow arthroplasty restored function to the patients who had had a failed prosthesis without infection.     

Biochemistry and biomechanics of healing tendon: Part II. Effects of combined laser therapy and electrical stimulation

Twenty-two closed Achilles tendon ruptures caused by sports injuries in 22 patients (average age, 37.6 years) were repaired with Kirschmayer core suture and cross-stitch epitenon suture, and early active ankle motion with weightbearing was implemented after surgery. This study was undertaken to evaluate the effectiveness of the repair technique and rehabilitation protocol by assessing clinical results and magnetic resonance imaging findings. The follow-up period averaged 24.6 months. Twenty of the tendons (91%) healed without rerupture, and two tendons (9%) suffered a partial rerupture at 23 and 56 days, respectively. Active ankle extension reached from the minus range to 0 degree in an average of 9.7 days, and ankle motion recovered to normal in an average of 6.0 weeks. Full weightbearing without heel raising became possible in an average of 16.4 days, and heel raising with both legs became possible in an average of 7.3 weeks. The patients returned to full sports activity in 13.1 weeks. The interval until the area of high-intensity signal at the tendon repair site on T2-weighted magnetic resonance imaging scans became intermediate-intensity signal averaged 6.9 weeks, and the tendon repair site became low-intensity signal in an average of 12.6 weeks, demonstrating excellent tendon healing. Treatment employing Kirschmayer core suture and cross-stitch epitenon suture may help athletes return to sports activity in a shorter period than that allowed by previous methods of repair for Achilles tendon ruptures.     

Intra-articular fractures of the distal end of the radius treated with an adjustable fixator system

Twenty-five wrists with comminuted, displaced, intra-articular fractures of the distal radius were prospectively treated with an adjustable external fixator for an average of 51 days. Twenty fractures (80% [20 of 25] were available for follow-up) in 16 adults (mean age, 34 years) were treated with the Wrist Jack external fixator system (Hand Biomechanics Lab, Sacramento, CA) and evaluated at a mean follow-up period of 25 months. Ten patients (12 fractures) sustained high-energy trauma with multiple injuries, while 6 patients (8 fractures) sustained isolated distal radius fractures. Percutaneous pins supplemented the fixation in 6 fractures. All fractures were reduced to restore articular congruity to within 1 mm. At follow-up, 5% were excellent, 75% good, 20% fair, and none as poor using the demerit point system of Gartland and Werley as modified by Sarmiento. Grip strength averaged 80% of the unaffected limb. Seventeen of the 20 fractures showed some evidence of articular incongruity at follow-up evaluation. Restoration of palmar tilt, radial inclination, radial length, and range of motion were at acceptable values. Subjective analysis confirmed 85% of the patients to have only occasional pain or none at all and 15% to have some pain with weakness or limitation of motion. Two patients required additional surgery: 1 underwent a Darrach procedure and the other a tendon transfer for a rupture of the extensor pollicis longus tendon. Results suggest that an external fixator system provides an additional alternative to the surgical armamentarium for an otherwise difficult fracture fixation problem.     

Müllerian duct cyst masquerading as chronic prostatitis: diagnosis with magnetic resonance imaging using a phased array surface coil

A retrospective study was designed to verify how often an anatomic variation caused the radial sensory nerve entrapment at the forearm (Wartenberg's syndrome). This variation, in which the superficial branch of the radial nerve emerges from under the fascia between two slips of a split brachioradialis tendon, was mentioned once in a clinical textbook as a basis for nerve entrapment but was found to occur in 5 of 150 dissected arms in 4 of 75 cadavers (3.3% of the investigated arms) in a recent anatomic study. To evaluate the incidence of this variation, 143 operative reports from patients who had Wartenberg's syndrome were reviewed. The variation was observed in seven patients. We conclude that any operation for Wartenberg's syndrome should include a thorough investigation of the site where the radial sensory nerve emerges from under the fascia and, if the nerve emerges through a split brachioradialis tendon, the anomalous tendon slip should be divided.     

The differential effect of personality on computer-based treatment of agoraphobia

A case of index flexor digitorum profundus and median nerve entrapment by bony fracture after reduction as a complication of distal radial fracture in an 11-year-old male is described. After release of tendon and nerve the patient had a good functional result.     

Surgical repair of Achilles tendon rupture. Comparison of surgical with conservative treatment

Achilles tendon suture combined with a triceps surae tendon tip-over graft was performed in 314 patients with acute rupture of the Achilles tendon between 1980 and 1991. Analysis of these cases showed a low tissue complication rate compared with that reported in the literature. An average of 8.1 years after repair, 223 patients were examined using Holz's scale of clinical assessment after Achilles tendon repair. The results were 'good' in 87.4%, 'fair' in 11.2% and 'poor' in 1.4%. The re-rupture rate was very low (0.4%). These results are better than the re-rupture rate after surgical repair with solely end-to-end suture or after conservative immobilizing or conservative functional treatment. In conclusion, these data show that the fascial reinforcement is a valuable complement to the tendon suture.     

Serratus anterior dysfunction. Recognition and treatment

Recognition of scapular winging may be difficult, and potential errors in treatment can result. Such treatment errors may cause morbidity for the patient. In addition, electrical evidence of long thoracic nerve injury usually is required to confirm the etiology of scapular winging as being caused by serratus anterior dysfunction. Although various conditions may result in scapular winging, primary serratus anterior dysfunction can be treated effectively by transfer of the pectoralis major tendon; however, this surgical approach sometimes may given an unacceptable cosmesis, and there may be local morbidity to the donor site of the iliotibial band graft that is used to augment the tendon transfer. The authors report eight patients with primary chronic scapulothoracic winging refractory to conservative treatment. Five of these patients had an incorrect diagnosis, and this resulted in 17 surgical procedures without resolution of their pain or improvement of function. Of the eight patients who required additional surgery to stabilize the scapula, only five patients had an electromyographic study that showed long thoracic nerve palsy, although all patients had profound scapulothoracic winging. All patients underwent a modified pectoralis major transfer with autogenous semitendinosus and gracilis tendon augmentation using two small incisions. Although one patient had a postoperative infection develop, the remaining seven patients had resolution of their winging, improved function, and satisfactory cosmesis.     

Effects of the neuropeptide thyrotropin-releasing hormone on GABAergic synaptic transmission of CA1 neurons of the rat hippocampal slice during hypoxia

Thirty-six consecutive patients with 37 complete tears of the ulnar collateral ligament of the thumb metacarpophalangeal (MP) joint were treated with primary repair using a miniature intraosseous suture anchor. Thirty patients were evaluated by clinical examination or by questionnaire at an average of 11 months after repair. Loss of interphalangeal joint motion averaged 15 degrees on the involved side versus the other side, while loss of MP joint motion averaged 10 degrees. There was no significant difference on stress testing measurements between repaired and nonrepaired thumbs. There were no instances of nerve injury, infection, device failure, or reoperation. The authors concluded that this is a safe and effective method for repair of complete tears of the ulnar collateral ligament of the thumb MP joint.     

Responses of the skin over the dorsum to sunlight in hairless descendants of Mexican hairless dogs

18 consecutive cases of delayed rupture of the extensor pollicis longus tendon were recorded during 5 years; 4 were spontaneous, and 14 after distal radius fracture, most of which were undisplaced or only slightly displaced. 15 cases were operated upon with tendon transfers: 13 had extensor indicis proprius transfer, 1 transfer of the extensor carpi radialis longus, and 1 reoperated with the extensor communis to the little finger as a motor unit. Subjectively, nearly complete satisfaction was reported; all patients were able to elevate the thumb to the level of the palm and full independent index finger movements were noted. In this 5-year-period 4,400 patients with distal radius fractures were treated, giving an incidence of delayed tendon rupture after distal radius fracture of 0.3 percent.     

Reconstruction of the distal aspect of the radius with use of an osteoarticular allograft after excision of a skeletal tumor

Twenty-four patients had reconstruction of the distal aspect of the radius with use of an osteoarticular allograft, between 1974 and 1992, after excision of a giant-cell tumor (twenty patients), a desmoplastic fibroma (two patients), a chondrosarcoma (one patient), or an angiosarcoma (one patient). Nine giant-cell tumors were recurrent lesions, and eleven were extracompartmental primary lesions that had extended through the cortex or subchondral bone. The average age of the patients was 31.5 years (range, fifteen to sixty-one years); thirteen patients were female and eleven were male. Seventeen lesions involved the right wrist and seven involved the left wrist. The reconstruction was performed through a dorsoradial incision with use of a size-matched, preserved, fresh-frozen, distal radial allograft. All procedures included internal fixation and reconstruction of the radiocarpal ligaments. All patients were followed for a minimum of two years (average, 10.9 years; range, 2.1 to 22.3 years). At the time of follow-up, two patients -- one who had a giant-cell tumor and one who had a desmoplastic fibroma -- had a local recurrence. Eight patients needed a revision of the osteoarticular allograft, at an average of 8.1 years (range, 0.8 to 17.8 years) after the initial reconstruction. Seven of these patients had an arthrodesis and one had an amputation. The reason for the revision was a fracture of the allograft in four patients, recurrence of the tumor in one, pain in two, and volar dislocation of the carpus in one. There were fourteen other complications, including ulnocarpal impaction necessitating excision of the distal aspect of the ulna (four), painful hardware necessitating removal (four), rupture of the extensor pollicis longus tendon necessitating transfer of the extensor indicis proprius (two), fracture of the allograft necessitating open reduction and internal fixation (two), volar dislocation of the carpus necessitating closed reduction (one), and a ganglion of the dorsal aspect of the wrist necessitating excision (one). Of the sixteen patients in whom the osteoarticular allograft survived, three did not have pain, nine had pain in association with strenuous activities, and four had pain in association with moderate activities. Three patients reported no functional limitation, nine had limitation in the ability to perform strenuous activities, and four had limitation in the ability to perform moderate activities. The average range of motion of the wrist was 36 degrees of dorsiflexion, 21 degrees of volar flexion, 16 degrees of radial deviation, 15 degrees of ulnar deviation, 58 degrees of supination, and 72 degrees of pronation. Reconstruction of the distal aspect of the radius with use of an osteoarticular allograft was associated with a low rate of recurrence of the tumor, a moderately high rate of revision, little pain in association with common activities, good function, and a moderate range of motion. Osteoarticular allografts are an option for reconstruction of the distal aspect of the radius after excision of a malignant tumor or a recurrent or locally invasive benign lesion.     

Alternative operative exposures of the posterior aspect of the humeral diaphysis with reference to the radial nerve

An anatomical study was performed to define the course of the radial nerve in the posterior aspect of the arm, with particular reference to its relationship to operative exposures of the posterior aspect of the humeral diaphysis. In ten cadaveric specimens, the radial nerve was found to cross the posterior aspect of the humerus from an average of 20.7 +/- 1.2 centimeters proximal to the medial epicondyle to 14.2 +/- 0.6 centimeters proximal to the lateral epicondyle. As it crossed the posterior aspect of the humerus in each specimen, the nerve had several branches to the lateral head of the triceps; however, no branches were found innervating the medial head of the triceps in the posterior aspect of any of the specimens. At the lateral aspect of the humerus, the nerve trifurcated into a branch to the medial head of the triceps, the lower lateral brachial cutaneous nerve, and the continuation of the radial nerve into the distal part of the upper arm and the forearm. Three operative approaches were performed in each specimen. The posterior triceps-splitting approach exposed an average of 15.4 +/- 0.8 centimeters of the humerus from the lateral epicondyle to the point at which the radial nerve crossed the posterior aspect of the humerus. For the second approach, the radial nerve was mobilized proximally to allow an additional six centimeters of the humeral diaphysis to be visualized. The third approach (the modified posterior approach) involved the identification of the radial nerve distally as it crossed the lateral aspect of the humerus, followed by reflection of both the lateral and the medial heads of the triceps medially. This exposure permitted visualization of 26.2 +/- 0.4 centimeters of the humeral diaphysis from the lateral epicondyle proximally. The results after use of the modified posterior approach in seven patients were also reviewed.     

Treatment of interphalangeal hyperflexion and metacarpophalangeal hyperextension of the thumb in combined low median-ulnar nerve palsy

A method of treatment of interphalangeal hyperflexion and metacarpophalangeal hyperextension of the thumb in combined low median-ulnar nerve palsy is described. The flexor pollicis longus tendon is divided longitudinally into 2 slips. One tendon strip is cut distally, extracted from the fibro-osseous canal, passed superficial to the tendon sheath, and attached to its previous insertion. An extensor indicis proprius opposition transfer was simultaneously performed. Eleven patients were monitored for 1 to 4 years after surgery. All results were positive, and there were no recurrences of either Froment's or Jeanne's sign.     

Tendon injury repair in a war wound

During 18 months of the 1991-1992 war against Croatia, 4425 injured were treated at the Department of Surgery, Osijek University Hospital. Among them 46 had tendon injuries, 20 with tendon laceration and 26 with total rupture. In 12 wounded primary repair was performed, 4 of an extensor tendon, 7 of a flexor tendon and 1 of both flexor and extensor. Four patients with primary flexor tendon repair had a good functional result. In other 34 no primary repair was done. Good function was achieved in 18 cases.     

Osteosynthesis of the hand--indications, technique, results

Between January 1st 1992 and December 31st 1993 140 non-complex (i.e. nerve, vascular, tendon injuries) fractures of the peripheral hand skeleton were operated at the Policlinic of the Kantonsspital Basel. In a retrospective study we analyzed results, complications and absence from work. We treated 110 male and 30 female patients with a mean age of 47 years. 45 fractures were treated by plate fixation, 45 by screw fixation, 53 times we applied k-wires and once a mini-fix-ex (AO-Prototype). Plate and screw fixation were performed with AO-mini-implants. 90% of our patients had an uneventful postoperative course. In spite of functional after-treatment we noted in 8.6% of the patients a relevant loss of movement leading to operative tenolysis in 7 patients. Fractures at the level of PIP were most frequently associated with loss of movement. Absence from work was 59 days in average (1-206)! Conclusions: Peripheral osteosynthesis of the hand (non-complex) are effectively treated on an out-patient basis. In spite of functional after-treatment about 10% of patients have a relevant postoperative reduction in motility. Absence from work is relatively long after operative treatment of peripheral hand fractures.     

Anterior tibialis tendon ruptures: an outcome analysis of operative versus nonoperative treatment

Ruptures of the anterior tibialis tendon are a rare clinical entity. Case reports in the literature reveal a total of 28 cases. Unfortunately, because of the limited discourse in the orthopaedic literature, there are few guidelines regarding the treatment for these injuries. This study analyzes the treatment of 16 anterior tibialis tendon ruptures. Eight patients in this group had operative treatment of their ruptures, and eight patients had nonsurgical treatment of their ruptures. The average follow-up for the operative and nonoperative patients were 6.68 years and 3.86 years, respectively. The Foot and Ankle Outcome questionnaire provided by the American Academy of Orthopaedic Surgeons and an outcome-based foot score described by Kitaoka et al. were used as the methods of analysis. Our outcome results show no statistically significant difference between operative and nonoperative treatment in anterior tibialis tendon ruptures. The lack of statistical difference between operative and nonoperative groups may be a reflection of the age bimodality present in this study. Elderly low demand patients were treated nonsurgically and young active patients were treated operatively. Therefore, despite a lack of statistical difference present in the outcome of both groups, we still maintain the need to repair/reconstruct anterior tibialis tendon ruptures in young active patients with high functional demands. The deficits present in the nonoperative group, we believe, would not be well tolerated in a young high functional demand patient. Nonsurgical management is an appropriate alternative in low demand elderly patients.     

Treatment of nonunion of the humerus using the Ilizarov external fixator

Ilizarov's method of monofocal compression was used in 30 humeri with a diaphyseal pseudarthrosis. Twenty-one patients had previous surgery but had loosening of the osteosynthesis material. Nine patients initially were treated with a hanging cast, resulting in interfragmentary distraction. Fourteen nonunions were hypertrophic, and 16 were atrophic, of which six were infected. A complete circular frame was used only in the first nine patients, whereas the remaining 21 patients were treated with the modified semicircular fixator. Union was obtained in all but two patients, with an average consolidation time of 4.5 months (range, 2.5-10 months). No patient required additional bone grafting. Apart from superficial pin tract infection seen in most of the patients, three had a minor temporary sensory neurologic problem. Four patients experienced a second fracture after removal of the fixator that required a second application of an Ilizarov frame. Although similar results with regard to union are reported after plate osteosynthesis, there was no radial nerve palsy or deep infection in this series, indicating that the treatment by the Ilizarov technique is associated with less complications. The authors' findings suggest that the Ilizarov method is a reliable treatment for humeral nonunions, even after multiple previous operations or in the event of infection.     

Long-term results of surgical treatment of thumb polydactyly

One hundred thirteen hands exhibiting thumb polydactyly were treated and followed up for an average of 49 months. Of these, 109 hands were treated by resection of a supernumerary hypoplastic thumb. Radial thumbs were resected in 107 hands and ulnar thumbs in 2 hands. Four hands were treated using a modified Bilhaut procedure. According to a modified Tada's evaluation, the results were evaluated as good in 97 hands, fair in 12 hands, and poor in 4 hands. Patients and/or their parents were satisfied with the results in 100 hands and dissatisfied with the results in 13 hands. The factors that influenced the surgical results were analyzed. The incidence of unsatisfactory results was relatively high in Wassel types 3, 5, and 6 and triphalangeal-type thumb polydactyly. It was higher when the ulnar digit was removed than when the radial digit was removed. The results for those patients treated between 1983 and 1991 were better than for those treated between 1976 and 1982. The type of deformity, type of procedure, and skillfulness of the surgeon were factors in the results after surgery.
