[Extensor digitorum brevis muscle flap: its help in coverage of distal foot defects. Report of six cases].

From January 1997 to march 2002, six extensor digitorum brevis muscle flaps have been used in four women and two men. Their ages were between five and 65-years-old. The defects were localised in the hallux in three cases, the dorsum of foot in one case, the other toes in one case and the external border of foot in one case. The defects were secondary to burn retraction in four cases, secondary to trauma in one case and secondary to osteomyelitis in another case. All the flaps were elevated on the distal dorsalis pedis artery with a retrograde flow. With an average of four years follow-up, all defects covered were very satisfying and there is no functional sequellae.

[The protected tendinous graft in zone 2 or fibroblast trap].

INTRODUCTION: We present a simple technique for preventing adhesions to tendon grafts in zone 2. A silicone tube is cut longitudinally and the third of its diameter is removed. It is then introduced under the pulley with the slot towards the skeleton. The tendon graft is introduced into this tube which will protect it from adhesions except at the slot level where fibroblasts create a new vasculature. MATERIALS AND METHODS: Between April 2002 and April 2003, we have used this technique in three patients, two in their thumbs and one in the long finger. In the Boyes classification, one thumb lesion corresponded to stage 1 and the other two cases to stage 4. The main pulleys were preserved. The tube measured 12 cm in length, and extended from the proximal juncture to the distal one (Pulvertaft technique). After 5 weeks of strict immobilization, the tube was withdrawn and the patients began active mobilization. RESULTS: After 8 weeks, comparison of the results with the opposite hand showed: Normal extension in all cases. Flexion deficit of 15 degrees in the thumb interphalangeal joints. Flexion deficit of 20 degrees in the proximal and distal interphalangeal joints of the long finger. There were no reported complications. With a mean follow-up of 1 year, these results were stable. CONCLUSION: These results support the contention that a good blood supply to the tendon and a good gliding surface have been developed with this technique. The tube seems to work as a fibroblast trap and blocks harmful adhesions.

[The "necktie lasso": a new technique for the simultaneous treatment of Wartenberg's sign and claw deformities in the hand due to ulnar nerve palsy].

The "necktie lasso" is a new technique that allows the simultaneous active treatment, of both Wartenberg's sign and claw deformity of the fifth and the fourth digits in the hand with ulnar nerve palsy. The flexor sublimis of the fourth digit is taken by a palmar approach. It is then divided into two strips up to the proximal part of the palm; The radial strip is used as a classical "direct lasso" to treat the claw deformity of the fourth digit; The ulnar strip is wound around the base of the fifth digit by a palmar and dorsal approaches at the level of the proximal phalanx, like a necktie, being medial to its radial pedicle, dorsal and superficial to its extensor apparatus, then lateral to its ulnar pedicle; It is then recovered in the palm and sutured to itself. From September 1998 to April 2003, this technique has been used in eight patients aged between 21 and 35 years old and suffering from post traumatic low ulnar nerve palsy. It was always very effective in dealing with Wartenberg's sign: the active adduction of the fifth digit appearing at the start of flexion. The claw deformity of the fourth and fifth digits was equally actively corrected. No complications are reported in this series. With a mean follow-up of 3 years there was no recurrence of any of the deformities.

[The fasciomusculocutaneous flap at the leg. About 9 clinical cases].

The fasciomusculocutaneous flap at the leg (FMC) include a muscle strip in the classic dissection of the fasciocutaneous flap (FC); this muscle survives only by the musculocutaneous vessels perforators. This muscle improves the trophic quality of the classic FC flap and allows him to bring easily muscle to the lower third of the leg and sole of the foot. From october 96 to january 2001, 9 posterior FMC flaps have been used in 9 men, their ages were between 22 and 61-years-old, 8 of these flaps were distally based and 1 was proximally based. The muscle strip came from the medial gastrocnemius muscle, its lengh and its width corresponded to the dimension of this muscle but the depth has never exceeded 10-12 mm. The skin defects have a diameter ranging from 7 to 10 cm and were localised in 3 cases in the sole of the foot, in 5 cases in the lower third of the leg with 1 case of tibial osteomyelitis and in 1 case in the external part of the knee. All these defects were secondary to trauma. No complications were reported with this technique. There was no vascular problems with the muscle strip: its bleeding was checked at the operating room and at 3 weeks when the pedicle was severed. All these patients were hospitalized between 4 and 5 weeks. With an average of 30 months follow-up all the defects covered were very satisfying and the case of the osteomyelitis was healed. There is no functional sequellae and the aesthetic sequellae are those of the classic FC flaps at the leg.

[The bilobed flap: a very efficient method in aesthetic reconstruction of small skin defects at the alar and tip regions of the nose].

From October 1996 to January 2001, 20 patients (14 men and six women) ranging from 36 to 75 years old have been treated for their small skin defects of the nose by using the bilobed flap. These skin defects were located in 15 cases at the alar region and in five cases at the tip region. They were secondary to the resection of basal cell carcinoma in 17 cases and benign tumors in three cases. Their diameter ranged from 8 to 17 mm and in all these cases there was no involvement of the lining or cartilage. The design used for this bilobed flap was the Zitelli one, based on some mathematical principles; its base was medial or lateral depending on the site of the defect. With this method, the skin defects were reconstructed esthetically without any distortion of local anatomy of the nose with skin having the same color, texture and thickness. With an average of 28 month follow-up, all these reconstructions were stable with discreet scars and without the trapdoor phenomenon. No complications were reported. Esthetic reconstruction of such subunit nasal skin defects is easily done by this technique and is better than that obtained by the majority of others methods.

[Iterative surgery for goiter].

AIM: Identify and resolve problems related to iterative surgery for goiter. PATIENTS AND METHOD: Fifty-nine patients who underwent surgery for recurrent benign goiter between 1990 and 1999 were included in the study. RESULTS: Forty-two patients had lobectomy and isthmusectomy (71.2 and 17 patients had subtotal thyroidectomy (28.8%). The delay from initial surgery to recurrence was less than 5 years for 44% of the patients and was more than 10 years for 17.8%. There was no post-operative mortality and no recurrent laryngeal nerve injury. Early post-operative hypocalcemia occurred in 2 patients (3.3%). CONCLUSION: The goal of revision surgery for recurrent goiter is total thyroidectomy. Prevention is a rational management scheme for thyroid nodules.
