[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).

[Review of 10 patients with pure perilunate carpal dislocation at a minimum of 18years follow-up]. / Revue à 18ans de recul minimum, de 10 patients présentant une luxation périlunaire isolée du carpe.

OBJECTIVE: To evaluate, in long-term, the functional abilities and the occurrence of osteoarthritis in patients treated for a posterior perilunate carpal dislocation without bone lesion associated. PATIENTS AND METHOD: This was a monocentric retrospective observational study on patients operated on at the University Hospital of Guadeloupe for a posterior perilunate dislocation without bone lesion associated with a minimum of 18years of follow-up. Ten patients were included with a mean follow-up of 22.8years. The evaluation criteria were clinical (PRWE, QuickDASH, pain, grip strength, wrist joint mobility, Watson and Reagan tests, Cooney functional score) and radiographic (Gilula curves, carpal height, carpal ulnar translation, scapholunate and radiolunar angles, scapholunate and triquetro-lunar interlines in statics and dynamics, Herzberg's classification of complications). RESULTS: The average Cooney score was 67.5/100. Mean PRWE and QuickDASH scores were 33.9 and 24.8 respectively. The mean flexion-extension arc on the injured side was 71.5° (66.7% compared to the healthy side). Mean grip strength was 27kg (72.8% compared to the healthy side). The prevalence of osteoarthritis was 60%, with three A types, two A1 types, one B type and four B1 types according to Herzberg. CONCLUSION: The factors influencing the long-term prognosis are the initial displacement of the lunate, the quality of the reduction and the presence of chronic carpal instability, particularly scapholunate. The high prevalence of osteoarthritis in our series (60%) is apparently not correlated with the functional capacities of patients over the long term.

[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.

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.

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.

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.

[Kienböck's disease in a nine-year-old boy: a case report]. / Maladie de Kienböck chez un garçon de neuf ans : à propos d'un cas.

The authors report a case of Kienböck's disease in a nine-year-old male gymnast, treated conservatively. It resulted in a clinically normal wrist and complete revascularisation of the lunate on MRI. This case suggests that the natural course of Kienböck's disease can be more favourable in children as compared to adults.

Acute carpal tunnel syndrome secondary to pyogenic tenosynovitis.

[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.

[Elbow arthroscopy]. / L'arthroscopie du coude.

This symposium of the French Arthroscopic Society is the 2005 state of the art of elbow arthrosocpy in France. A survey reports 499 cases during 2 years with a rate of complication higher than the arthroscopies of other joints (6% of minor and 1% of major complications). The main indication is the removal of loose bodies. They can come from arthritis, chondromatosis, osteochondritis or fracture. The most accurate radiologic examination is an arthroCTscan. The main pronostic factor is the cartilage status. Arthrolysis is the second indication. We performed a retrospective and a prospective studies to compare open and arthroscopic surgery. Results are almost similar with a significant higher improvement in flexion (7 degrees ) in the open group. Open surgery seems more efficient but with a franck loss of motion in the postoperative course. However, in this group elbows were preoperatively stiffer in relation with a trauma event instead of sport related microtrauma in the arthroscopically treated group. Removal of necrotic fragment combined with abrasion in osteochondritis of the capitulum yields to good results with 82% of patients resuming to sports. Long term prognosis is unknown as the joint line is narrowed at a 3 years follow up. Arthroscopy is usefull in synovial diseases as resection of synovial folds or removal of tumors like villonodular synovitis. In the treatment of epicondylitis, the results of our retrospective study are not so good as those reported in the literature. But in our comparative study the results are similar to the open surgery group. The numerous procedures and the different follow up in these two groups did not allow to give statistical analysis. Elbow arthroscopy is a hyper specialty with more and more advanced procedures.

[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.

[Arthroscopic treatment of dorsal wrist ganglia]. / Traitement arthroscopique des kystes synoviaux dorsaux du poignet.

Incidentally discovered in 1987, arthroscopic treatment of dorsal wrist ganglia is based on our knowledge of their physiopathology which in turn benefits from the arthroscopic wrist evaluation. Dorsal wrist ganglia arise in the radiocarpal space from the dorsal part of the scapholunate ligament and migrate along the dorsal wrist capsule. According to their position above or under the dorsal intercarpal ligament, their cutaneous projection may vary. The basis of the arthroscopic treatment of wrist ganglia is, as with open surgery, the capsular resection in front of their origin. Arthroscopic resection is made either from dorsal radio-carpal or midcarpal approaches with little morbidity. Scars are unnoticeable, wrist mobility and strength close to normal by three months, which is the delay for dorsal wrist pain, always very limited, to disappear. The recurrence rate is however still debatable. Close to zero in some series, we had almost 20% recurrence rate in our series, with half of patients who reccur after two years follow-up. This variability in the recurrence rate also exists with open techniques. The only prospective and randomized study available to date found no differences between the two techniques, according to the recurrence rate.

[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.

Full thickness skin graft for nail unit reconstruction.

A retrospective study of 13 patients assessed the use of a full thickness skin graft for nail unit reconstruction after total nail unit removal for nail bed malignancies. No failures of the graft were observed and no patient had recurrence of the malignant tumour at 4 year follow-up. Full thickness skin grafting is a simple procedure which provides a good cosmetic outcome and does not produce significant donor site morbidity.

[Arthroscopic treatment of tennis elbow: preliminary experience with 14 patients]. / Traitement arthroscopique de l'épicondylalgie d'origine tendineuse: une expérience préliminaire á propos de 14 cas.

The purpose of the study was to report our experience in a preliminary series of patients who underwent arthroscopic treatment of tennis elbow in order to appreciate effectiveness of this method. Between September 2000 and February 2004, we treated arthroscopically fourteen patients with epicondylitis which failed to respond to medical treatment given for a mean duration of 15.8 months. We used the technique described by Baker in 1999. Briefly, the external capsule was sectioned followed by section of the extensor carpi radialis brevis and extensor digitorum communis insertions on the epicondyle. Section was continued until muscle fibers were visible. Mean patient age was 45 years (range 36-55). Five patients were victims of occupational accidents and one had an occupational disease. One patient suffered from fibromyalgia. All patients were reviewed at a mean follow-up of 11.5 months. We used the Mayo Clinic score to assess outcome which was excellent or good in nine patients, fair in one and poor in four. Despite these modest preliminary results, arthroscopy appears to be well indicated for this pathological condition. The ideal treatment remains a question of discussion.

Carpal tunnel syndrome and computer exposure at work in two large complementary cohorts.

OBJECTIVES: The boom in computer use and concurrent high rates in musculoskeletal complaints and carpal tunnel syndrome (CTS) among users have led to a controversy about a possible link. Most studies have used cross-sectional designs and shown no association. The present study used longitudinal data from two large complementary cohorts to evaluate a possible relationship between CTS and the performance of computer work. SETTINGS AND PARTICIPANTS: The Cosali cohort is a representative sample of a French working population that evaluated CTS using standardised clinical examinations and assessed self-reported computer use. The PrediCTS cohort study enrolled newly hired clerical, service and construction workers in several industries in the USA, evaluated CTS using symptoms and nerve conduction studies (NCS), and estimated exposures to computer work using a job exposure matrix. PRIMARY AND SECONDARY OUTCOME MEASURES: During a follow-up of 3-5 years, the association between new cases of CTS and computer work was calculated using logistic regression models adjusting for sex, age, obesity and relevant associated disorders. RESULTS: In the Cosali study, 1551 workers (41.8%) completed follow-up physical examinations; 36 (2.3%) participants were diagnosed with CTS. In the PrediCTS study, 711 workers (64.2%) completed follow-up evaluations, whereas 31 (4.3%) had new cases of CTS. The adjusted OR for the group with the highest exposure to computer use was 0.39 (0.17; 0.89) in the Cosali cohort and 0.16 (0.05; 0.59) in the PrediCTS cohort. CONCLUSIONS: Data from two large cohorts in two different countries showed no association between computer work and new cases of CTS among workers in diverse jobs with varying job exposures. CTS is far more common among workers in non-computer related jobs; prevention efforts and work-related compensation programmes should focus on workers performing forceful hand exertion.

Radiocarpal dislocations: classification and proposal for treatment. A review of twenty-seven cases.

BACKGROUND: The radiographic characteristics and treatment of radiocarpal dislocation are not well defined. There have been only two reported series of more than eight patients. Thus, there are many questions concerning treatment and functional results. METHODS: Two groups of patients were defined. Group 1 included all patients with pure radiocarpal dislocation and patients with only a fracture of the tip of the radial styloid process. Group 2 included patients with radiocarpal dislocation and an associated fracture of the radial styloid process that involved more than one-third of the width of the scaphoid fossa. A retrospective review and a clinical evaluation were performed. RESULTS: From 1975 to 1998, we observed twenty-seven cases of radiocarpal dislocation. Four were displaced volarly, and twenty-three were displaced dorsally. Fourteen patients presented with associated lesions. Four patients were treated with closed reduction and immobilization in a plaster cast; five, with percutaneous Kirschner wire fixation and cast immobilization; and two, with an external fixator. Eleven patients had open reduction with Kirschner wire fixation and cast immobilization. The seven patients in Group 1 had a highly unstable injury, and four of the seven patients presented with ulnar translation of the carpus. At the time of follow-up, at an average of 26.8 months, pronation averaged 76 degrees; supination, 66 degrees; wrist flexion, 54 degrees; wrist extension, 54 degrees; radial inclination, 15 degrees; and ulnar inclination, 18 degrees. The average grip strength was 27 kg. Group 2 included twenty patients. Only thirteen, with dorsal dislocation, were evaluated at the time of follow-up, which averaged fifty-one months. At that time, six reported no pain; four, slight pain; and two, moderate pain. Pronation averaged 63 degrees; supination, 76 degrees; wrist flexion, 51 degrees; wrist extension, 56 degrees; radial inclination, 21 degrees; and ulnar inclination, 39 degrees. Grip strength averaged 38 kg. Seven patients had complications. CONCLUSIONS: On the basis of our experience and a review of the literature, we believe that patients with pure radiocarpal dislocation or with radiocarpal dislocation with a fracture of the tip of the radial styloid process should be treated with reattachment of the ligaments through a volar approach. In patients with radiocarpal dislocation and a fracture of the radial styloid process that involves more than one-third of the width of the scaphoid fossa, the ligaments are still attached to the radial fragment. We believe that in this group of patients, exact articular reduction should be performed through a dorsal approach. Additional studies are needed to support these hypotheses.

Observer reliability in CT and MRI of the abdomen/pelvis.

The purpose of this research was to evaluate two sources of error in the performance of computerized tomography (CT) and magnetic resonance imaging (MRI) of the abdomen/pelvis. The sources of error assessed were inter- and intra-observer reliability. Thirty abdomen/pelvis CT scans were randomly selected from each of three hospitals (university, VA, military) with different CT scanners. Two radiologists were recruited from each site to be CT observers. Forty-five abdomen/pelvis MRI scans were randomly selected from two institutions with different MRI scanners. Four observers were recruited to read the MRI scans. All scans were read blind without clinical information or patient identification. Overall inter-observer and intra-observer diagnostic agreement was significantly higher for MRI compared to CT. Inter-observer diagnostic agreement rates were also significantly higher for MRI when the etiologies of neoplastic vascular and metabolic/toxic were assigned. Observer experience in CT (range: 5-9 yr) or MRI (range: 2-4 yr) was not statistically associated with improved diagnostic agreement. This research addresses many of the criticisms of the MRI literature and compares MRI favorably to CT.

Fracture of the distal radius. A prospective comparison between trans-styloid and Kapandji fixations.

We performed a prospective study on 96 patients with extra-articular or intra-articular fractures of the distal radius with a dorsally displaced posteromedial fragment. After closed reduction, we compared trans-styloid fixation and immobilisation with Kapandji fixation and early mobilisation. Forty-two patients of mean age 57.1 years +/- 18.1 (SD) were treated by trans-styloid K-wire fixation and 45 days of short-arm cast immobilisation. Fifty-four patients of mean age 57.7 years +/- 18.7 (SD) had Kapandji fixation and immediate mobilisation according to the originator. All the patients had clinical and radiological review at about six weeks and at 3, 6, 12 and 24 months after the operation. Pain, range of movement and grip strength were tested clinically, and changes in dorsal tilt, radial tilt, ulnar variance, and radial shortening were assessed radiologically. Statistical analysis was applied to comparisons with the normal opposite wrist. Pain and reflex sympathetic dystrophy were more frequent after Kapandji fixation and early mobilisation, but the range of motion was better although this became statistically insignificant after six weeks. The radiological reduction was better soon after Kapandji fixation, but there was some loss of reduction and increased radial shortening during the first three postoperative months. The clinical result at two years was similar in both groups.
