[Ballistic hand trauma].

46 victims of projectile accidents or explosions were treated over a 5 years period between 1984 and 1989. 3 categories were distinguished: injuries due to a single projectile (12 cases), only inducing serious bone damage and, apart from 3 immediate amputations, the final result was satisfactory. Injuries due to multiple scattered projectiles (11 cases), less severe in terms of the initial lesions, not requiring any amputations, with good results in 8 cases. Explosion injuries (23 cases) in which the effect of the explosion induced considerable initial lesions leading to one hand amputation and 33 finger amputations; the association of skeletal and soft tissue lesions raises the problem of excision and primary cover, requiring large flaps. The course is long and 8 out of 26 hands had serious sequelae, while the reconstruction of an elementary pinch can be considered to be an acceptable result in the other cases.

[Comparative study of the effects of a local antibiotic and a local antiseptic in emergency hand surgery].

An open randomised comparative study was conducted in patients presenting with a hand injury requiring a surgical operation, in order to compare the efficacy of topical application of rifamycin SV with that of iodinated polyvidone dermal solution, in terms of the quality and rate of healing evaluated by the clinician, 268 patients were included in the study and 223 of them participated in the analysis of the results. Analysis of the results demonstrated the following conclusions: signs of infection developed in 8 patients in the rifamycin SV group (7%) and in 20 patients in the iodinated polyvidone group (18.5%). This difference was significant (p = 0.011) in favour of rifamycin SV. The rate of healing was considered to be rapid in 10% of patients in the rifamycin SV group and in 4% of patients in the iodinated polyvidone group. It was considered to be slow in 14% of the subjects in the rifamycin SV group and in 21% of those in the iodinated polyvidone group. This difference was also significant in favour of the rifamycin SV group (p = 0.038). In terms of local tolerance, 32 patients equally distributed between the two treatment groups developed signs of cutaneous intolerance.

[Expansion of the facial integument in children].

In the light of four clinical cases of paediatric facial reconstruction, the authors discuss the advantages and indications of the cutaneous expansion technique which can be combined with other plastic surgery procedures to obtain an abundant skin with ideal texture and sensitivity and minimal scars. Operations for cicatricial alopecia, very extensive forehead naevus, preauricular tumour and nasal mutilation are described.

Conversion to arthroplasty from proximal interphalangeal joint arthrodesis.

Fifteen patients, interested by the functional results of certain arthroplasties and discouraged by those of their arthrodesis, agreed to undergo disarthrodesis. This operation was performed by arthroplasty with Swanson implant under the following 4 conditions: excellent skin cover, an intact flexor system, articular fusion in good position with preservation of the normal length and axis of the finger, the understanding by the patient that an arthroplasty does not mean normal range of movement but, at best, recovery of a limited but functional, stable and pain-free range of movement. 12 cases operated between 1971 and 1984 have been followed for a mean of 39 postoperative months. The mean gain of active movement from a fused joint was 56.8. The postoperative course was always uneventful in these particularly motivated patients and 11 out of 12 were satisfied with their result.

The transfer of the abductor digiti quinti: palliative treatment for paralysis of the superficial thenar muscles.

Described by Huber in 1921, the transfer of the abductor digiti quinti constitutes an elegant solution to paralysis of thumb opposition. Interest in this operation was renewed and defended by Littler and more recently by Manske and McCarroll. The technique is simple and we do not believe that it is necessary to detach the muscle from its proximal insertion, thus preserving the force of the transfer. The advantages are as follows: elective reconstitution of antepulsion of the thumb column, which supposes that the adductors and the flexors are intact. A small operative field with limited routes of approach reducing scarring to a minimum. The cosmetic advantage is evident with reconstitution of the thenar contour. The functional loss is minor and in our opinion the abductor digiti quinti appears to be less inexpendable than the flexor digitorum sublimis or the extensor pollicis. The limitations of the operation are the absence of functional deep thenar muscles and adductors as well as, of course, the absence of a healthy abductor digiti quinti as in associated ulnar palsy. The results in 8 operations lead us to think that, when possible, the transfer of the abductor digiti quinti is a particularly interesting solution to paralysis in women and children, but probably insufficient in manual hard labor workers, at least in those who need strong abduction of their thumb.

Resection arthroplasty with Swanson's implant for posttraumatic stiffness of proximal interphalangeal joints.

Proximal interphalangeal joint resection arthroplasty with Swanson's implant should be considered as a simplified new hinge joint with a simplified shorter but isometric extensor system which will work if the flexor system is intact. The procedure is indicated in cases of severe, ill-tolerated, fixed joint contractures. Functional improvement with restoration of some range of motion can be expected. Patients should be aware that they will not regain a complete range of motion at the PIP joint, there will be limited involvement of the distal interphalangeal joint, and there may be some discomfort in cold weather. The procedure is not recommended for patients with a high risk of postoperative dystrophy, on workmen's compensation, or unable to understand the goals and limitations of a joint resection arthroplasty.

Treatment of old introclable lesions of the extensors of the middle finger by resection arthroplasty with implant.

Traumatic boutonniere deformity may become fixed and cannot be reduced when the joint cartilage become altered. We propose a resection arthroplasty with a Swanson's silicone implant as a valuable solution for this problem as it simplifies the joint and the extensor apparatus. We use a transverse approach through the extensor tendon which enables to restore a good balance between bone and tendon and seems to avoid some adhesions. Results of 17 operations with a minimum follow up of 12 months show that 40 degrees of motion have been recovered in an angle sector which corrects the deformity. The final evaluation is good if compared to the severity of the initial status.
