RESUMO

Motor dysfunction of the 1st dorsal interosseous (DIO) muscle is typically observed in low and high ulnar nerve palsy. This causes weak thumb-index pinch, which can be disabling for the patient. Various reconstructive techniques have been described; however, the choice often depends on the surgeon's experience, the presence of associated neurovascular and musculotendinous injuries, as well as the requirements of the palliative surgery schedule. Nerve transfers can be proposed when patients present early in the course of the disease. Tendon transfers are often a last resort when late presentation occurs. Tendon transfers must follow general principles: the insertion is made on the 1st DIO terminal tendon; the tension must be adjusted in a neutral position to avoid excessive tension, and immobilization is maintained for 4 weeks. Although many transfers are possible, the extensor pollicis brevis transfer is our preferred option. This donor does not require additional tendon grafting, has a direct line of pull close to that of the 1st DIO and is not often used for other reconstructive purposes.

RESUMO

BACKGROUND: Identifying men living with HIV in sub-Saharan Africa (SSA) is critical to end the epidemic. We describe the underlying factors of unawareness among men aged 15-59 years who ever tested for HIV in 13 SSA countries. METHODS: Using pooled data from the nationally representative Population-based HIV Impact Assessments, we fit a log-binomial regression model to identify characteristics related to HIV positivity among HIV-positive unaware and HIV-negative men ever tested for HIV. RESULTS: A total of 114,776 men were interviewed and tested for HIV; 4.4% were HIV-positive. Of those, 33.7% were unaware of their HIV-positive status, (range: 20.2%-58.7%, in Rwanda and Cote d'Ivoire). Most unaware men reported they had ever received an HIV test (63.0%). Age, region, marital status, and education were significantly associated with HIV positivity. Men who had HIV-positive sexual partners (adjusted prevalence ratio [aPR]: 5.73; confidence interval [95% CI]: 4.13 to 7.95) or sexual partners with unknown HIV status (aPR: 2.32; 95% CI: 1.89 to 2.84) were more likely to be HIV-positive unaware, as were men who tested more than 12 months compared with HIV-negative men who tested within 12 months before the interview (aPR: 1.58; 95% CI: 1.31 to 1.91). Tuberculosis diagnosis and not being circumcised were also associated with HIV positivity. CONCLUSION: Targeting subgroups of men at risk for infection who once tested negative could improve yield of testing programs. Interventions include improving partner testing, frequency of testing, outreach and educational strategies, and availability of HIV testing where men are accessing routine health services.

RESUMO

Controversy persists around trapeziectomy as standard of care in thumb base osteoarthritis. The difficulty of management of failure requires the utmost caution in choice of the initial technique. We here report a retrospective series of 10 revision procedures following trapeziectomy, supported by a review of literature. The main cause of revision was collapse of the thumb column resulting in arthrogenic contact of the first metacarpal with the scaphoid. At a mean 73.3 months' follow-up, 5 patients had to undergo additional surgery. Mean VAS pain score was 2.9; 5 patients were pain-free. Strength was more severely impaired than joint motion, resulting in disappointing functional results. The present outcomes are consistent with the literature, which mostly comprises heterogeneous series, making it impossible draw conclusions to guide practice. The most common option seems to be to perform a new ligament procedure, with or without tendon or pyrocarbon interposition, and was the one that provided the only good result in the present series. Other techniques (composite graft, non-autogenic interposition, scaphometacarpal prosthesis) seem promising, and deserve large-scale evaluation. Thus, the gold-standard status of trapeziectomy should be weighed against the observation of these multi-operated patients in situations of therapeutic impasse. Should indications for first-line trapeziectomy be restricted, especially in patients with a revision risk factor? LEVEL OF EVIDENCE: 4.

RESUMO

Sport climbing is increasingly popular and consultations by climbers in hand surgery departments are on the increase. The pathologies related to this sport concern essentially the pulley system, tendons being rarely affected. We report the case of a male climber who presented an atypical rupture of the flexor superficialis tendon in his left middle finger sustained when using an atypical climbing grip technique: the "hook grip". This consists in extension of the metacarpophalangeal joints and maximal flexion of the proximal interphalangeal joints with force exerted only on middle phalanx of the middle finger. A biomechanical analysis using finger musculoskeletal modeling was performed to compare the hook grip to other grips, and the patient's recovery performance was assessed. Adapted functional treatment with physiotherapy seems to have been a good option for the treatment of this atypical lesion since the patient recovered normal use of his finger in daily life. He recovered maximal force in climbing holds. The biomechanical analysis confirmed that the atypical "hook grip" was likely at the origin of the rupture, since flexor digitorum superficialis tendon force for this grip is greater than in other climbing grip techniques. The "hook grip" seems to be dangerous and should be used cautiously by climbers to prevent similar pathology. Additionally, the patient should henceforth be careful when climbing, since the biomechanical model showed that the remaining flexor digitorum profundus tendon was overused.

RESUMO

BACKGROUND: To minimize the risk of viscera exposure for parietal or calverial reconstruction after tumor removal, we used the two-stage free flap strategy. The flap was transferred a few days before tumor resection and left in a standby position until the second stage. PATIENTS AND METHOD: We conducted a retrospective monocentric study. All patients who underwent reconstruction with the two-stage free flap strategy after tumor resection since 2000 were included. RESULTS: We performed 14 two-stage flaps (8 for calvaria, 3 for abdomen, and 3 for thorax) on 12 patients. The average skin paddle surface was 318 cm2. The mean operative time was 274min for the first stage and 172min for the second stage. The average time between the two stages was 8.8 days (2 to 24 days). One flap necrosis, one venous thrombosis, and one hematoma were observed after the first stage. Partial skin paddle necrosis (2 flaps) and infections (3 flaps) occurred after the second stage. The mean follow-up was 20 months (6 to 61 months), and two patients had tumor recurrence. CONCLUSIONS: The two-stage free flap strategy is another option for major oncological reconstructions, to be safe and reliable some rules must be followed. The flap must contain a large skin paddle to ensure flap autonomization and to allow for complete tight plication of the flap between the two stages, which limits germ colonization. A short delay between the two stages (<12 days) decreases the risk of infection. The presence of a plastic surgeon during the second stage decreases the risk of pedicle trauma.

RESUMO

The arm is less often concerned by reconstructive surgeries than more distal parts of the upper extremity. However, when affected, the arm is frequently part of complex mutilating injuries involving composite defects. For a given traumatic or oncologic defect, there are several reconstructive options and choosing the right sequence may pose a challenge even to the most experienced surgeon. The latter must integrate not only functional and esthetic requirements, but also the surgeon's habits, especially in situations of emergency. Once life-threatening conditions are averted, wound debridement, bony stabilization, neurovascular, and cutaneous reconstruction tailored to the defects should be performed in a single-stage procedure. Functionally, prompt bony stabilization is necessary to allow early mobilization. Diaphyseal shortening of the humerus can be a salvage procedure to avoid nerve and vascular grafting, with good biomechanical tolerance up to 5cm. Restoration of adequate elbow motion sometimes requires muscle transfer and should be a main concern, as proper positioning of the hand during daily activities demands a functional elbow joint. Esthetically, the surgeon must choose the most cosmetic skin coverage option whilst limiting morbidity of the donor site area. The flaps vascularized by the sub- scapular or thoraco-dorsal vessels are the most useful flaps for arm reconstruction. This paper discusses the reconstructive sequence of complex defects of the arm and provides a review of commonly used reconstructive techniques supported with illustrative cases.

RESUMO

Ulnar impaction syndrome (UIS) is a frequent cause of ulnar-sided wrist pain. Several open and arthroscopic surgery techniques have been described. Ulnar shortening osteotomy (USO) is often the method of choice. It has the advantage of leveling the distal radioulnar joint extra-articularly while maintaining the integrity of the soft tissues that stabilize the joint. This retrospective study reports the short-term outcomes of 20 patients who underwent surgery between 2013 and 2015. USO was performed with a locked plate and a new compression device (Alians®, Newclip™, Haute Goulaine, France). Preoperative and postoperative ulnar variance were measured on wrist X-rays in neutral pronation-supination. Functional outcomes were evaluated with the QuickDASH score and the pain on VAS (visual analog scale). Postoperative range of motion and grip strength were compared to those of the contralateral wrist. The average follow-up was 16 months (4 to 28 months). Preoperative ulnar variance was positive with an average of 4mm (1-11mm). The average length of the final ulna shortening was 3.5mm (1.5-6mm); the mean time to union was 4 months (3-12 months). The average QuickDASH was 12 and pain had decreased 2.4mm on the VAS. The results achieved with this new compression plate designed specifically for USO are similar to those described in the literature. This kind of device has an easily reproducible technique and can reduce the operative time. LEVEL OF EVIDENCE: IV.

RESUMO

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis that can take many clinical forms. Its diagnosis is difficult and often delayed. We report the case of a 36-year-old man with PG complicating a chemical burn of the wrist. This mode of atypical onset delayed the diagnosis and the initiation of appropriate treatment. This was not sufficient since the patient's hand was amputated at his request because of unbearable pain, and failed treatment. Surgeons should be aware of this pathology in cases of rapidly progressing ulcers, especially if aggravated by repeated debridement.

RESUMO

We present a case report of a failed posterior interosseous flap with distal pedicle rescued by an extensor digiti minimi (EDM) island pedicle flap supplied by the posterior interosseous artery (PIOA) in reverse flow to cover a soft tissue defect in the hand of a 25-year-old man. We subsequently performed an anatomical study on 5 cadaver limbs to determine the EDM muscle's vascularization: it was segmental, multiple and came from the PIOA. The rotation arc reached the dorsal side of the metacarpophalangeal (MCP) joints, as well as the distal part of the thumb. The indications selected are the same as those of the distal pedicle flap: defect on dorsal side of the hand and MCP joints, coverage of carpal tunnel, failure of posterior interosseous flap. This study describes a new flap and adds to our understanding of the EDM muscle's vascularization.

RESUMO

The comminuted distal radius fractures among elderly people are usually linked to osteoporosis, and repairing them in this context is a therapeutical challenge. Several teams have reported good results of radius resurfacing. The goal of our study was to evaluate the usability of the wrist in a new series of patients after surgery. We performed a monocentric retrospective study on the data of the medical files. All the included patients were older than 65 years and received a wrist hemiarthroplasty according to the criteria that have been established by the in charge medical team. Eleven patients have been included, their average age was 80.4 years old, and the average follow-up was 18.3 months. The average QuickDASH Score was 59 (27-95). The Visual Analogue Scale for pain was in average 3.8/10 and the average mobility was: flexion 36° (12-50), extension 27° (12-50), radial deviation 15° (12-15), ulnar deviation 26° (12-40), pronation-supination range of motion 164° (150-170). The average measured strength was 44% (16-72%) of the strength of the unaffected hand. Our results are rather modest, probably because of insufficient follow-up and very severe fractures. Furthermore, the implant that has been used does not take into account the distal radioulnar joint. Another bound of this treatment is the complexity of surgical revision in case of bad result. So far, hemiarthroplasty cannot be considered as the standard treatment for complex fractures of the distal radius.

RESUMO

Closed rupture of the thumb flexor tendon pulleys is rare. Although anatomical and biomechanical studies have exposed the roles played by the pulleys in flexor pollicis longus (FPL) function, no standardized surgical management has yet been defined, in contrast to situations where pulley reconstruction is required in the fingers. We describe a case of rupture of the three pulleys in the thumb that probably occurred after violent thumb grasp during childbirth in the absence of any other trauma. We reconstructed the A1 pulley only using an extensor retinaculum graft because no remnants of the native pulleys were present.

RESUMO

BACKGROUND: The free vascularised fibular flap (FVFF) is widely used to treat bone defects, although it must be harvested from a healthy site. The objective of this study was to assess clinical morbidity and radiological changes at the FVFF donor site in children. HYPOTHESIS: Distal fibular stabilisation using a tibial strut decreases the prevalence of valgus ankle deformity. MATERIAL AND METHOD: Thirty-one children managed at two centres between 1994 and 2014 were included. Mean age was 8.9 years (range, 2-14 years) and mean follow-up was 6.6 years (range, 2-21 years). Early and delayed complications were evaluated. RESULTS: Of the 17 early complications, 82.4% resolved fully within 7 months. Valgus ankle deformity developed in 6 (19.4%) patients. Age-residual fibula index under 16 was not significantly associated with valgus ankle deformity, although the P-value was borderline (P<0.058). Residual distal fibula length did not predict valgus ankle deformity. Three techniques were used for fibular reconstruction: syndesmotic screw, tibial strut, and both. None of these techniques prevented the occurrence of valgus ankle deformity. DISCUSSION: Clinical donor-site morbidity after FVFF harvesting, although noticeable, usually resolved promptly. Taken alone, an age-residual fibula index under 16 did not predict valgus ankle deformity. We recommend a distal tibio-fibular quadricortical syndesmotic screw or combined syndesmotic screw-tibial strut fixation to prevent valgus ankle deformity, which is common when a tibial strut is used alone. LEVEL OF EVIDENCE: IV.

RESUMO

Management of complex intra-articular fractures of the distal radius in young active patients must aim to restore normal anatomy. For optimal planning of the surgical procedure, a thorough analysis of the fracture with appropriate radiological exams and diagnosis of frequently associated lesions are necessary. Surgical management involves use of various types of internal or external fixation. Routine use of standardized analysis tools for these fractures along with prospective follow-up should allow us to define guidelines for each situation in the near future.

RESUMO

Trapeziometacarpal (TMC) osteoarthritis is a common, disabling condition that mostly affects women. The demand for surgical treatment is growing and the patients are becoming younger, adding to the challenge. Surgery can only be proposed after failure of well-conducted conservative treatment and requires a complete X-ray assessment. In the early stages, conservative surgery measures can be used to stabilize the joint or realign it in cases of dysplasia, but in most cases, patients are seen with more advanced arthritis and joint replacement must be considered. The ideal arthroplasty technique has yet to be defined but nevertheless, the chosen technique must be well-suited to the patient's condition. Although many studies have been published on this topic, they do not help us define the treatment indications. Prospective studies focusing on the patient rather than evaluating a certain surgical technique are needed. Trapeziectomy with or without ligament reconstruction is still considered the gold standard, but the challenges associated with treating its complications limit its indications. Arthrodesis, interposition or arthroplasty are also viable therapeutic options. The patient must be sufficiently informed to be able to contribute to choosing the indication.

RESUMO

Streptococcal bone and joint infections are less common than staphylococcal cases. Few studies have reported the cases with well-identified Streptococcus species. Their clinical features and prognosis are not clearly known to date. Moreover, no treatment regimen has yet been clarified. We reviewed the streptococcal bone and joint infection cases managed in our centres from January 2009 to December 2013. We described the epidemiology, clinical and microbiologic characteristics, treatment approach and outcome. Among the 93 cases, 83% of patients were men with a median age of 60 years, and 90% of patients had comorbidities or risk factors. Bacteraemia occurred in 14% of cases. Serious complications occurred in six patients, including severe sepsis (two cases) and infective endocarditis (two cases). Orthopaedic device infections were observed in 35% of cases, including 17 patients with internal osteosynthesis device infection, 14 with prosthetic joint infection and three with vertebral osteosynthesis device infection. The median time between orthopaedic device implantation and onset of infection was 447 days. Fourteen species of Streptococcus were identified, including 97 isolates using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and three isolates using molecular identification. The five most represented species included S. agalactiae (37%), S. dysgalactiae (12%), S. anginosus (11%), S. constellatus (10%) and S. pneumoniae (9%). Streptococci isolates were susceptible to amoxicillin, with the exception of one S. mitis isolate. Remission 1 year after the end of treatment was recorded in 83%. One patient died of infection; eight patients had infections that failed to respond to treatment; and seven patients experienced relapse. Twenty patients (22%) had an unfavourable functional outcome, including 19 amputations and one arthrodesis. Five significant prognostic factors associated with an unfavourable clinical outcome were identified, including peripheral neuropathy (p 0.009), peripheral arterial disease (p 0.019), diabetes mellitus (p 0.031), location in the femur (p 0.0036), location in the foot (p 0.0475), osteitis without an orthopaedic device (p 0.041) and infection caused by S. dysgalactiae (p 0.020). The rate of poor outcomes remains high despite the low number of Streptococcus isolates resistant to antibiotics. Some prognostic factors, such as the presence of S. dysgalactiae, are associated with an unfavourable clinical outcome. Antibiotic regimens of streptococcal bone and joint infections are not standardized and need to be further investigated.

RESUMO

Mycetoma is a chronic inflammatory cutaneous and subcutaneous pathology caused by either a fongic (eumycetoma) or bacterial (actinomycetoma) infection, which lead to a granulomatous tumefaction with multiple sinuses. When localized in the foot this infection is named "Madura foot". This infection is endemic to tropical and subtropical regions and rarely occurs in western countries. A historical case in Europe of a foot mycetoma evolving since 20 years without any treatment is presented. A histopathologic diagnosis of actinomycetoma has been done in 1987. The patient presented a severe Staphylococcus aureus chronic osteitis leading to a trans-tibial amputation. This case allows to present this infection which, even if rarely presented in France, can be meet especially among a migrant's population.

RESUMO

Forearm vascular anatomical variations are common and may have complications during flaps harvesting. This article describes the presence of an ulnar superficial artery, revealed while harvesting a radial forearm flap. The prevalence of this anatomical variation is between 0.7 and 9.4%. It may have important consequences while covering loss of substance with a radial forearm flap. Unknown, there is a risk of vascular injury which may lead to distal ischemia of the upper limb. Preoperative diagnosis can anticipate this risk and harvest a fascio-cutaneous flap centered on a perforator of this artery.

RESUMO

The aim of this study was to determine if pisotriquetral instability is present after neurolysis of the median nerve in the wrist. Fifty-five patients who underwent carpal tunnel release between December 2005 and March 2009 were included in this retrospective study. The surgical procedure consisted of cutting the transverse carpal ligament under local anesthesia through an anterior approach. Instability was evaluated clinically and radiologically by measuring the pisometacarpal angle. The mean patient age was 61years and the mean follow-up 42months. Only 9% of patients complained of pain on the ulnar side of wrist. The pisometacarpal angle in all the operated wrists was the same as in the non-operated wrists. Our findings suggest there is no pisotriquetral instability after median nerve neurolysis.

RESUMO

First described by Ambroise Paré in the mid-17th century complex, regional pain syndrome (CRPS) can be defined as an articular and periarticular pain syndrome associated with vasomotor deregulation triggered by various stresses with no relationship between the intensity of the initial injury and severity of the continuing pain. Several names have been given to Type 1 complex regional pain syndrome (CRPS-I): causalgia, reflex sympathetic dystrophy, shoulder-hand syndrome and algodystrophy. The reported incidence of CRPS-I is about 25 per 100,000. Predisposing factors are tobacco consumption and being female (W/M ratio=4). Although all the limbs can be affected, the upper limb is by far the most affected. CRPS-I is a classic complication of distal radius fractures (4-37%) and carpal tunnel surgery (2-4%). Early diagnosis and management are the most important elements of treatment because this syndrome has a long and disabling course. Some of the proposed treatments include NSAIDs, antidepressants and anticonvulsants. The latter, despite their good analgesic effects, do not cure CRPS-I. In select cases, a surgical procedure aiming at removing a nociceptive stimulus can lead to spectacular improvements.

RESUMO

We report the finding of a subtotal rupture of the median nerve caused by a "bridge" or"easel" erosion due to a sequela of childhood wrist fracture. This unpublished observation was made during a carpal tunnel release procedure on an 80-year-old patient who was operated on for recurrence of a severe carpal tunnel syndrome 30 years after a previous neurolysis. If the flexor tendon ruptures are widely described, as well as nerve sections following high energy trauma, the median nerve rupture caused by its erosion over a bony projection has never been published at the best of our knowledge.
