ABSTRACT
We assessed the effect of four-corner intercarpal fusion with locking plate without bone graft on daily activities and pain in patients with stage II and III scapholunate advanced collapse and scaphoid nonunion. Twenty-one patients who underwent four-corner fusion with scaphoidectomy without bone graft were evaluated with the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Visual Analog Scale (VAS) pain scores before and 16 months after surgery. We also compared postoperative grip strength between the operated and the healthy side. A principal component analysis was used to establish the relationship between functional benefit, immobilization period and number of physiotherapy sessions. We compared our results with published data. VAS and QuickDASH scores improved significantly. Loss of strength was observed postoperatively. QuickDASH score improved the most with a short immobilization period. No significant difference was found relative to the literature for follow-up time, range of motion, grip strength and QuickDASH score. All patients had bone fusion after 1 year. Four-corner fusion with locking plate is a procedure that reduces pain and improves functional scores. Our results are equal to those reported in the literature with bone graft. The union rate seemed high despite the absence of bone graft but was only assessed by x rays. This study allowed us to establish a treatment guideline: a shorter immobilization leads to better recovery.

UNLABELLED: Advanced stages of Kienböck's disease are treated by several techniques, one of which is Graner's procedure, nearly abandoned nowadays. The results of long-term follow-up of a series of four cases Graner's procedure are presented. Four patients were reviewed with a follow-up of 25years. There were two women and two men mean aged 37years at the time of surgery. Two of them were manual workers. Graner's procedure was the first surgery in three cases and secondary to failure of radius shortening in one case of Stage IIIa. Three patients underwent bone healing and the fourth benefited secondarily from radiocarpal arthrodesis. At maximal follow-up, the mean DASH score was 36.6 and pain assessed by visual analogic scale was 3.25 out of 10; the range of movement was half of the opposite side; the wrist strength was 80.9% of the opposite side. In the three consolidated cases, a spontaneous remodeling of the radiocarpal articular surfaces was noted. Graner's procedure is logical as it aims at creating a new radiocarpal articulation, either by the fusion of the lunate with the capitate (Graner I) or by replacing the lunate with the head of the capitate (Graner II and III). However, this old procedure should no longer be one of the surgical procedures for Kienböck disease due to its drawbacks: necrosis or non-union of the head of the capitate, necessity to perform a wrist fusion in the long-term and side effects of bone graft harvesting. LEVEL OF EVIDENCE: II. Retrospective study.

The treatment of ulnar nerve compression at the elbow remains controversial. No single technique has yet proven its superiority. We describe a technique combining the advantages of the mini-invasive approach with those of transposition. We present the results of 30 patients, of mean age 52 years, who underwent anterior subcutaneous transposition of the ulnar nerve using a mini-invasive approach with a follow-up of more than six months. The incision measures 3 cm. The results were evaluated by measuring pain intensity, quick disabilities of the arm shoulder and hand (DASH), grip strength and pinch, and McGowan score, pre- and post-operatively. All parameters were improved post-operative. The mean pain score went from 5.5 to 4, the quick DASH from 48 to 38, mean grip strength from 28 to 31 kg, and mean pinch strength from 4.7 to 6.4 kg. The McGowan score was also improved; pre-operatively, there were 16 patients at stage III, seven patients stage II, seven patients stage I, and post-operatively there was one patient stage III, three patients stage II, 16 patients stage I, and 10 patients stage 0. Analysis of our series shows that a 3 cm incision without endoscopy allows subcutanous transposition, with results at least as good as those with other techniques. The advantages of our technique are that it is easy, has a limited approach, preserves blood supply, allows placement of the nerve in a favourable environment, and decreases nerve stretching during elbow flexion.

INTRODUCTION: It is usual to stop the intake of oral anticoagulants (anti-vitamin K) before surgery. Some authors have shown that during minimal surgery, the relay with low molecular weight heparin (LMWH) may lead to more thromboembolic complications. We present a prospective comparative study while evaluating the results of stopping or continuing anticoagulants in the surgery for carpal tunnel syndrome. MATERIAL AND METHODS: Our series included 21 patients (24 hands) taking anticoagulants on a long-term basis. For the first nine patients (group I), treatment with anticoagulants was stopped before the surgery. For the following 12 patients (group II), treatment with anticoagulants was not interrupted. The evaluation was based on the measurement of pain (VAS), functional score of the Quick D.A.S.H. and grip strength (Jamar®) and search for a haematoma or thromboembolism). RESULTS: The pain decreased by 3.5 points in both groups. The Quick D.A.S.H. decreased by 19.9 and 27.7 points in groups I and II, respectively. The average grip strength decreased by 2.5 kg in group I and increased by 3.8 kg in group II. A subcutaneous haematoma that got healed by itself was observed in group II. We did not observe any thromboembolic complications. DISCUSSION: In conclusion, it seems pointless to stop anticoagulants before surgical treatment of carpal tunnel. The first reason is that continuing anticoagulants does not result in a bleeding risk. The second reason is that this approach removes the theoretical risk of thromboembolic complications during a poorly monitored relay.
ABSTRACT
The infra-millimetre vessels are difficult to suture, because the placement of forceps in the lumen is delicate and threads often cross the walls. The technique of the IntraVascular Stent (IVaS), developed to remedy it, did not make the proof of its superiority. The purpose of this study was to analyze the results of a variant, the Clip Stent. Our series included two groups of 10 rats. In group I, the artery of the tail was anastomosed by threads of nylon 10/0. In group II, the artery was anastomosed according to the technique of Clip Stent including three stages: introduction of a monothread of polypropylene 6/0, anastomosis by threads of nylon 10/0, ablation of the Clip Stent and the closure of possible leaks. The assessment consisted in measuring the time of anastomosis, in counting the number of separate threads and leaks, and in testing the permeability. The time of anastomosis was longer 12 minutes in the group II. The number of points by anastomosis was 6.5 in the group I and of 5.5 in the group II. The permeability was 90% in two groups. The Clip Stent is faster than the IVaS. It is useless to realize vascular threads of the lumen before the introduction of the stent. Once the stent in position, it cannot traumatize the intima and its migration is impossible. Contrary to the IVaS, the Clip Stent allows to realize the last threads stent in position, by releasing the tourniquet. The ablation is safe. Its superiority to the conventional methods remains to demonstrate by improving its introduction in the lumen.

The "heating lamp" is one of the complementary measures used to improve the survival rate of replantations and flaps. No publication demonstrated its efficiency, but burn injuries have been reported. The purpose of this study was to estimate the efficiency of the "heating lamp". A questionnaire was sent to the members of the French society for surgery of the Hand, 16 % of who answered. The heat emitted by three electric bulbs (energy saving, strand, halogen) was measured at room temperature at 10, 15, 20 and 25cm distance from the bulb over 4h. The pressure of capillary drip PFC of the pulp of the index was measured in 10 healthy subjects by a laser Doppler. The PFC was measured without source of heat, then at 38, 40 and 42°C, during 30min. Among the answers to the questionnaire, 67 % never use the heating lamp. Among the 33 % who use it, the protocol was variable; 18 control the temperature without precision, 18 use it continuously, and 23 use it more than 24hours. Nine reported complications, including eight burns (five flaps, three replantations). Subjectively, the majority of the users believe in its efficacy. Objectively, the heat emitted by the "heating lamp" was unimportant; whatever the distance from the source. The PFC did not vary with the temperature. The "heating lamp" is used empirically in microsurgery. The physical and physiological measures at the lower threshold for burns (43°C) show that it is ineffective. Burns have been reported. In conclusion, the "heating lamp" should no longer be a part of the therapeutic arsenal of the hand surgeon.
