[Perioperative antibiotics in the management of hand infection]. / Antibiothérapie périopératoire dans les infections de la main.

PURPOSE: There is no consensus on the utility of postoperative antibiotherapy in hand infections after surgical management. The aim of this study was to evaluate if the absence of postoperative antibiotic therapy was detrimental after surgical treatment. METHODS: We included 287 patients operated on for a hand infection between January 2018 and October 2023. Preoperative or postoperative antibiotic prescription was collected for every patient. Patients cured for their infection with a single surgery were classified as "simple evolution", while patients requiring repetitive surgery or who had at least one complication directly linked to the initial infection (extension of infection or necrosis) were considered "complicated". RESULTS: From a total of 287 patients, we included 188 paronychia, 40 phlegmons, 47 abscesses and 12 superinfected wounds. The revision surgery rate was 9.4%, and the complication rate was 27.2%. One hundred and seventeen (40.8%) patients received preoperative antibiotic therapy from emergency physicians or general practitioners, among whom a complication rate of 31.6% was observed. The causal link did not reach the significance threshold for the whole group of patients (P=0.079). However, preoperative antibiotic use in phlegmon patients was directly correlated with the occurrence of at least one complication (P=0.032). In all, 82.9% of patients did not require postoperative antibiotic therapy, 95% of whom had an uncomplicated course. CONCLUSIONS: Preoperative probabilistic antibiotic therapy is an independent risk factor for complications, particularly if given at a collected stage. Antibiotics should not be routinely prescribed postoperatively in a correct debridement is performed. We recommend that antibiotics be used only in very specific cases (osteitis, arthritis, necrosis and/or high-risk patients).

Metastatic tumour of the hand - Three new cases and a literature review.

Metastatic tumours of the hand are rare, and therefore, is the subject of only a few publications in the literature. We report on three new cases along with a retrospective and descriptive study with file and literature analysis dating from 1900 to 2017, which reported on 337 studies. To perform the statistical analysis, ordinary lease square regression was used to group the metastases into distal phalanx, proximal/middle phalanx, thumb, hand and carpus. We found 564 metastases at the hand for a total of 482 patients. Of the reported cases, 60% were male. The average age was 59 years. The main primary cancers were lung cancer (40%), followed by gastrointestinal (19%), genito-urinary (13%), gynaecological (11%) and ear, nose and throat (6%) cancers. The mean survival time was 7.2 months. Fifty-nine per cent was bone metastasis, 18% tissue metastasis and 3% cutaneous metastasis. In 20% of cases, the type of metastasis was not mentioned. Of all the tissue metastases, 47 (54%) were subungual and in that group, the thumb was the finger most commonly affected. Overall, metastases most commonly appeared in the distal phalanx, which can be explained by a greater vascularisation as well as microtraumatisms. Survival was independent of the epidemiological criteria and of the location and type of metastasis. Patients with primary urological cancer lived on average 3 months longer than patients with other types of primary cancers.

[Granular cells tumour (Abrikossof) of the ulnar nerve at the arm. A case report and literature review]. / Tumeur d'Abrikossof (tumeur à cellules granuleuses) du nerf ulnaire au bras. À propos d'un cas et revue de la littérature des tumeurs à cellules granuleuses du nerf ulnaire.

INTRODUCTION: Granular cell tumours are extremely rare on peripheral nerves, with an incidence of 0.029% of pathologic samples. In a literature review, we found only 5 cases involving the ulnar nerve, although considered the most frequently involvement nerve. CASE REPORT: A 32 year-old female from the French West Indies presented a severe arm pain with deficit of interosseous hand muscles. Imaging studies were in favour of a Schwanoma, but during surgery, we found an unremovable intra-neural tumour. Nerve biopsy revealed a granular cell tumour. Initial decision was observation only. However, within two years, tumour increased in size, along with pain aggravation and functional deficit. We performed a nerve resection (with adequate margins) with reconstruction using sural nerve graft associated with a neurotisation of the motor branch with the anterior interosseus nerve. At two years follow-up, no recurrence was observed. The scar is hypersensitive with moderate neuropathic pain. There is a sensory reinnervation of the fourth finger, with no motor recovery of the hand. We observed a slight recovery of flexor profundus tendons, which, in turn increased the claw hand. DISCUSSION: The five cases described in the literature were managed differently (biopsy only, excision, excision with reconstruction), with modest results. There is no recommended treatment. Our case is the first at arm level. We were able to perform complete resection, but functional result is poor. CONCLUSION: Granular cell tumours require treatment if symptomatic (pain, function loss), but, at the moment, there is no recommended treatment.

Advanced finger infection: more frequent than expected and mostly iatrogenic.

Some patients present at an advanced stage of their fingertip infection with an extension of the infection in anatomical spaces or into fragile structures. One hundred and twenty-five patients have been operated on for a finger infection. Forty-one patients (33%) have been treated at the "complication" stage, while 84 cases (67%) were considered "non-complicated". The delay between initial injury and the surgical treatment was 12 days in the "non-complicated" group versus 30 in the "complication" group (p < 0.001). Osteitis (39% of the complications), and flexor sheath infection (37%) were the most frequent complications. Prescribing preoperative antibiotics increases the risk of being in the "complicated" group at p = 0.09. One hundred and thirteen patients (90.4%) were cured of their infection after a single operation. Neither the cause of infection, nor the type of germ or associated diabetes increased the risk of complication in our series. A better education of the first interveners (general practitioner or emergency doctor) in hand infection care could reduce the rate of complication allowing a faster access to hand surgeons.

[Combined scaphoid and distal radius fractures in adults]. / Fractures du scaphoïde associées aux fractures de l'extrémité distale du radius chez l'adulte.

Although isolated distal radius and scaphoid fractures are common, the combination of both fractures is rare, with a reported frequency between 0.5% and 6%. This rarity is probably due to the fact that both fractures share the same injury mechanism. Published studies are limited, but most patients are males in their 40s and the injuries are typically due to high-energy trauma. In most studies, the distal radius fracture is displaced while the scaphoid fracture is not. Since the functional outcome depends of the severity of the radius fracture, we believe, as do others, that it is logical to fix both fractures with stable devices (i.e., screw fixation for the scaphoid, locking plate for the radius) to allow for early rehabilitation.

IFSSH scientific committee on skin coverage: 2015 report.

Skin coverage in hand reconstruction is a challenging and vast chapter in hand surgery; covering every aspect of it in a report is simply not feasible. Therefore, this report focuses on a few specific topics. The coverage of anatomical regions like the fingertips is common ground for hand surgeons worldwide, but in the last 10 years, various refinements have been published in order to optimize the reconstruction of this organ. Nevertheless, in many emergency departments, the amputation of badly injured fingertips, including the thumb, remains the preferred treatment. The main focus of this report is to counter this tendency by providing alternatives to surgeons. Large defects in the fingers involving more than one segment, defects in the palm and in the dorsum of the hand are currently debated in international meetings. The use of skin substitutes vs. the use of extremely refined microsurgical procedures vs. classic island flaps has generated animated discussions, which are also influenced by cultural and socioeconomic factors around the world. This report offers the views of six surgeons from four different countries, in the hope of animating discussions and suggesting new approaches.

Radial artery pseudoaneurysm: a rare complication after arthroscopic treatment of a volar wrist ganglion in a hemophilia patient.

Vascular complications of wrist arthroscopy are rare. We report the case of a 42-year-old male patient with a history of hemophilia who had a ganglion located where the radial pulse is taken that had been causing him pain for five months. After infusion of Exacyl (antifibrinolytic agent), the ganglion was drained arthroscopically. Fifteen days later, the patient presented with a pseudoaneurysm of the radial artery requiring urgent reoperation.

Severe granulomatous reaction associated with hypercalcemia occurring after silicone soft tissue augmentation of the buttocks: a case report.

UNLABELLED: Liquid silicone is a permanent filler. Its use to augment soft tissues for aesthetic purposes was widespread worldwide in the 1960s. Although initially considered to be biologically inert, this substance may cause, after its injection, an inflammatory granulomatous effect of variable severity and, in very rare cases, a severe hypercalcemia, which can be life threatening. The reported case highlights the well-known physiopathology of hypercalcemia, and the various therapeutic options are discussed.

[Treatment of Dupuytren's contracture by collagenase injection]. / Traitement des brides de la maladie de Dupuytren par la collagénase injectable.

Dupuytren's disease is a disorder of the palmar aponeurosis responsible for apparition of pathological collagen cords that will gradually lead to a digital retraction. These cords cause functional disability to the hand with a real handicap for the patient. No curative treatment exists currently in this disease. Injections of collagenase from Clostridium histolyticum cause lysis of the collagen present in the cords and cause an interruption of the palmar cord. It is a new treatment in the management of Dupuytren's disease. The use of collagenase injection in the treatment of palmar form of Dupuytren's disease gives good results in the short and medium terms. It is a simple, minimally invasive treatment, several studies have proven its effectiveness and it approximates percutaneous needle fasciotomy in its easy use and its indications. Patients should be well informed about local reactions and transient pain with the injection of C. histolyticum collagenase. Diffusion of this technique is still limited by: the assessment of its cost compared to that of other methods of treatment and particularly the needle fasciotomy, and the evaluation of results over the long-term.

[Intra-osseous ganglion cyst of the carpal bones. A review of the literature underlining the importance of systematic computed tomography]. / Kystes synoviaux intraosseux du carpe : intérêt de la tomodensitométrie systématique pour l'évaluation du risque fracturaire.

The intraosseous ganglion cyst (IOGC) is a benign and lytic bone tumor affecting mostly the metaphyseal and epiphyseal regions of long bones. Its location on the short bones, including the carpal bones has been little reported in the literature. Our review of the literature shows consensus about the surgical techniques to use, but there is currently no real consensus about its pathophysiology, and its diagnostic work-up. Complications related to this lesion (mainly the risk of pathologic fracture) are potentially serious, and can cause irreversible damage. They therefore require accurate assessment to guide the choice of medical or surgical treatment, including a CT scan, which - we believe - is essential.

Isolated Kaposi sarcoma of the finger pulp in an AIDS patient.

A 63-year-old woman with long-standing AIDS and previous Kaposi sarcomas of the lower limb presented to our consultation complaining of a painful left ring finger with pulp enlargement. X-rays revealed an osteolytic lesion of the distal phalanx. We suspected an isolated osseous Kaposi sarcoma and at surgery we found a hemorrhagic lesion with bone extension into the phalanx. Bone involvement is rare in Kaposi sarcoma and even rarer in patients without a cutaneous location.

[Ultrasonography for hand surgeons (lecture from the 46th meeting of French Society of Hand Surgery)]. / L'échographie pour le chirurgien de la main (conférence d'enseignement XLV(e) congrès de la Société française de chirurgie de la main).

Ultrasound examination is inexpensive, easily accessible and has numerous applications. Its diagnostic or even therapeutic use is developing in the context of hand surgery. The purpose of this work is to review the literature dealing with hand ultrasonograpy by recalling its physical basis and by showing the normal and pathological aspects of different structures and pathologies.

The intra-operative radius joystick test to diagnose complete disruption of the interosseous membrane.

Disruption of the interosseous membrane is easily missed in patients with Essex-Lopresti syndrome. None of the imaging techniques available for diagnosing disruption of the interosseous membrane are completely dependable. We undertook an investigation to identify whether a simple intra-operative test could be used to diagnose disruption of the interosseous membrane during surgery for fracture of the radial head and to see if the test was reproducible. We studied 20 cadaveric forearms after excision of the radial head, ten with and ten without disruption of the interosseous membrane. On each forearm, we performed the radius joystick test: moderate lateral traction was applied to the radial neck with the forearm in maximal pronation, to look for lateral displacement of the proximal radius indicating that the interosseous membrane had been disrupted. Each of six surgeons (three junior and three senior) performed the test on two consecutive days. Intra-observer agreement was 77% (95% confidence interval (CI) 67 to 85) and interobserver agreement was 97% (95% CI 92 to 100). Sensitivity was 100% (95% CI 97 to 100), specificity 88% (95% CI 81 to 93), positive predictive value 90% (95% CI 83 to 94), and negative predictive value 100%). This cadaveric study suggests that the radius joystick test may be useful for detecting disruption of the interosseous membrane in patients undergoing open surgery for fracture of the radial head and is reproducible. A confirmatory study in vivo is now required.

The middle radioulnar joint and triarticular forearm complex.

The forearm is composed of the radial and ulnar shafts, which are linked by the interosseous membrane and intercalated between the elbow and wrist. The radius and ulna are connected by three joints, the proximal, middle, and distal radioulnar joints. The forearm ensures pronation/supination and longitudinal load transfer. The biomechanical and clinical relevance of the proximal and distal radioulnar joints is well established. In contrast, the middle radioulnar joint was considered relatively unimportant until studies published in the last decade showed that it fulfils crucial biomechanical functions and is of considerable clinical significance. We believe the conventional concept in which the forearm is viewed as part of either the elbow or the wrist is outdated and that a more relevant concept describes the forearm as a triarticular complex that functions as a full-fledged entity. In this concept, the three forearm radioulnar joints (proximal, middle, distal) work together to provide stability, mobility and load transfer. Here, we will argue for the relevance of the triarticular complex concept based on published data about forearm biomechanics and pathological conditions.

Osteoid osteoma of the pisiform: a case report.

Osteoid osteoma of the pisiform is exceptional, and has been reported previously only once, in 1985, by Kernohan. This report presents a clinical case of osteoid osteoma of the pisisform assessed by CT-scanning, 3D reconstruction CT-scan images, MRI imaging and per-operative pictures.

Pulmonary embolism following thrombosis of the brachial vein after shoulder arthroscopy. A case report.

Thromboembolic complications are very rare after arthroscopic surgery of the shoulder. We report the case of a 25-year-old who presented thrombophlebitis of the brachial vein complicated by pulmonary embolism following arthroscopic surgery for posterior instability of the shoulder. No hemostasis impairment was found in this patient. The factors arguing in favor of thrombosis that had been retained from the literature were the lateral decubitus position with traction of the limb in its axis, prolonged surgical time, use of interscalene brachial plexus block, and a general condition susceptible to thrombosis (personal or family history of thromboembolism, genetic risk factor for thrombosis, smoking, obesity, neoplasia). There are currently no guidelines on the need for thromboembolism prevention during shoulder arthroscopy.

[Arthroscopic treatment of dorsal ganglion cyst at the wrist. About 54 cases]. / Résection arthroscopique des kystes synoviaux dorsaux du poignet: à propos de 54 cas.

INTRODUCTION: Ganglion cyst of the wrist can, some time, need surgery. Different arthroscopic technical procedures have been described. We report our experience in all articular resection of dorsal ganglion cyst of the wrist. OBJECTIVES: Evaluation of efficiency of resection of dorsal ganglion cyst of the wrist by of arthroscopic resection of the pedicle. METHODS: Fifty-four cysts of 52 patients have been evaluated retrospectively. Operative data, pain, strength, recurrence and complications have been collected. RESULTS: Average follow up was 28 months (6 to 78). Return to work was 8,8 days, operative time 41 minutes (25 to 90). In 67% cases, the operation was judged easy. Three surgeries had to be performed open. Complications were one hematoma and one neurodystrophy. Pain decrease from 3,37 to 1,76 on analogical pain scale. Flexion was 89% of opposite side, extension 88%. Sixteen recurrences (29.7%) were found. Sixty percent of those recurrences occurred during the first year experience. But independently of experience, the operative performance was foun difficult in 1 time on 3. CONCLUSION: Endoarticular arthroscopic resection of the pedicle of ganglion cyst is not so reproducible. In experimented hands, it remains a difficult procedure after a long learning curve with a recurrence rate 3 times higher from what is reported in literature for open surgery. For our discharge, our long follow-up can contain some cases of de novo cyst explaining this high rate, the learning curve is certainly the main reason for our high recurrence.

Acute carpal tunnel syndrome secondary to pyogenic tenosynovitis.

We report a case of acute carpal tunnel syndrome related to a spontaneous pyogenic tenosynovitis and a review of this clinical condition.

[Quality of information transfer for informed consent: an experimental study in 21 patients]. / Difficultés du transfert d'information en vue d'un consentement éclairé: etude expérimentale chez 21 patients.

PURPOSE OF THE STUDY: Delivering information to the patient, an ethical obligation recognized for years, has recently become a legal obligation. Proof of information delivery has become the legal responsibility of the surgeon. We conducted a prospective study to evaluate the quality of information transfer by assessing patient comprehension of information delivered in an orthopedic surgery unit. MATERIAL AND METHODS: All patients attending consultations before undergoing arthroscopic treatment for rotator cuff tendinopathy were enrolled in this study when the consultation was conducted in the presence of an observer. Two questionnaires, one for the patient and one for the surgeon, were used to collect given information about the pathological condition, the modalities of treatment, and the expected results of the treatment and its complications. RESULTS: All 21 patients included in the study considered they had been well informed and that they had understood their pathological condition as well as the complications of the proposed treatment. However, agreement between their stated comprehension and the information delivered was poor, varying from 15 to 50%. Furthermore, 90% of the patients stated they had understood the potential complications of the surgical procedure, despite the fact that the consulting surgeons had not (generally) provided information on such complications. DISCUSSION: There is a gap between what the surgeon says (or thinks he/she says) and what the patient understands. Potential biases in this study (non-unbiased observer) might explain this discordance which was probably related to the unequal relationship between the patient and the physician for any consultation. Therefore, the basis of informed consent cannot be found in the details concerning complications actually delivered to the patient. Surgeons must become aware that the patients understand very little of their explanations. This does not mean that the information should not be delivered but on the contrary that it must be. The important point is not necessarily the information content but rather the quality of the human relationship enabling information transfer.
