Lift, drill, fill and fix (LDFF): a new arthroscopic treatment for talar osteochondral defects.

PURPOSE: The purpose of this study was to describe the short-term clinical outcome of a new arthroscopic fixation technique for primary osteochondral talar defects: lift, drill, fill and fix (LDFF). METHODS: Seven patients underwent an arthroscopic LDFF surgery for osteochondral talar defects, the mean follow-up was 12 months (SD 0.6). Pre- and postoperative clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS) and the numeric rating scales (NRS) of pain at rest and during walking. Remodelling and bone ingrowth after LDFF were analysed on weight-bearing radiographs during follow-up. RESULTS: In all patients, LDFF led to an improvement of the AOFAS and NRS of pain. The AOFAS significantly improved from 63 to 99 (p < 0.001). The NRS of pain at rest significantly improved from 2.9 to 0.1 (p = 0.004), and pain with walking significantly improved from 7.6 to 0.1 (p < 0.001). On the final radiographs, five of seven patients showed remodelling and bone ingrowth after LDFF. CONCLUSIONS: The LDFF of an osteochondral talar defect appears to be a promising arthroscopic treatment option for primary talar osteochondral defects. Although the clinical and radiological results of 1-year follow-up are encouraging, more patients and longer follow-up are needed to draw any firm conclusions and determine whether the results stand the test of time. LEVEL OF EVIDENCE: Prospective case series. Therapeutic, Level IV.

[Generalized exanthematous pustular dermatophytid, a rare clinical presentation of dermatophytid reaction]. / La dermatophytide exanthématique et pustuleuse généralisée (DEPG), une présentation clinique rare de dermatophytide.

BACKGROUND: Dermatophytids are immunologically mediated dermatologic presentations secondary to sensitization to a dermatophyte infection. They are most frequently associated with toe-web intertrigo and usually present as localized, palmar, pruriginous vesicular eruptions. We report three original cases of generalized exanthematous pustular dermatophytid associated with kerions. PATIENTS: Two boys aged 11 and 6 years, and one girl aged 6 years initially presented with kerion secondary to Trichophyton tonsurans (case 1), Trichophyton soudanense (case 2) and Trichophyton mentagrophytes (case 3), respectively. Two to three days after initiation of griseofulvin treatment, all patients presented with a pustular eruption extending from the head to the trunk, associated in one case with fever of 39°C and inflammatory chondritis. Samples obtained from the pustular lesions were sterile, serum inflammatory markers were within the normal range and skin lesions resolved on oral corticosteroid treatment (prednisone 0.75 mg/kg, case 1) or high-potency topical steroids (cases 2 and 3) given as an adjunct to griseofulvin treatment (19 to 23 mg/kg/d). DISCUSSION: Dermatophytids occur during the acute phase of infection or within a few days of treatment initiation. Lesions are remote from the infection site, contain no dermatophyte, and resolve after treatment of the infection. We report three original cases of generalized exanthematous pustular dermatophytid, associated in one case with fever and inflammatory chondritis. The main differential diagnosis is acute generalized exanthematous pustulosis secondary to antifungal drugs. Differences in clinical presentation between the two enable the appropriate diagnosis to be made as well as continued use of the antifungal medication needed to cure the patient. General or topical steroids may also be used in combination.

Surgical treatment of an osteochondral lesion associated with stress fracture of the tarsal navicular: a case report.

We surgically treated an osteochondral lesion associated with a stress fracture of the tarsal navicular. The surgical procedure involved the confirmation and complete resection of the lesion under direct vision, followed by the transplantation of block-shaped iliac bone grafts. The postoperative computed tomography scan showed that the lesions had disappeared, the grafted bone had fused, and the stress fracture had healed. However, the tarsal navicular joint surface was slightly irregular. The patient was able to resume her sports activities 15 weeks after surgery. We have described a novel method to reconstruct the tarsal navicular after osteochondral lesion resection.

Gouty tophus as a rare cause of a Hepple stage V osteochondral lesion of the talus.

BACKGROUND: Talus osteochondral lesion is commonly associated with trauma, avascular necrosis or even genetic factors, but gouty tophus as a cause of Hepple stage V type talus osteochondral lesion is rare. CASE PRESENTATION: Here, we report a case of an 18-year-old man who complained of left medial deep ankle pain on ambulation. This young man had an extreme liking of sea food rich in purines and also sugar-sweetened drinks. He was diagnosed with a Hepple stage V type talus osteochondral lesion and was treated with medial malleolus osteotomy and an osteochondral graft. The talus osteochondral lesion was found to be a gouty tophus and was completely removed. Hypouricemic therapy was prescribed for 2 months, which allowed the patient to walk with a visual analogue score (VAS) score of 1. He was followed up for 12 months. CONCLUSIONS: Young people with an extreme liking of sea food rich in purines and also sugar-sweetened drinks may be at a risk of developing gout. Acute onset of ankle atraumatic pain, swelling with a high level of serum uric acid and a talus osteochondral lesion with cyst formation should make physicians consider a diagnosis of gout.

Cartilage degeneration is associated with augmented chemically-induced joint pain in rats: a pilot study.

BACKGROUND: Osteoarthritis arising from cartilage degeneration is the most common cause of joint pain. However, the relationship between joint pain and cartilage degeneration is not well understood. QUESTIONS/PURPOSES: We asked whether the inflammatory mediators participate in the joint pain in the presence of cartilage degeneration. METHODS: We observed electromyographic responses of hindlimb flexors to four inflammatory mediators (bradykinin, ATP, acetylcholine, and serotonin) injected in normal rat knees and in those with monosodium iodoacetate (MIA)-induced arthritis. RESULTS: Joint cartilage of all the rats with MIA-induced arthritis histologically showed severe degeneration. We observed greater magnitude and longer duration responses in the MIA-induced arthritis than normal joints with all four mediators. CONCLUSIONS: The data suggested nociceptors in osteoarthritic joints are more sensitive to inflammatory mediators than in normal joints. Such nociceptive sensitization to inflammatory mediators may participate in the joint pain in osteoarthritis.

Posterior tibial tendon dislocation: a systematic review of the literature and presentation of a case.

OBJECTIVE: In contrast to posterior tibial tendon lesions, dislocations of the posterior tibial tendon are thought to be 'extremely rare'. Diagnostic criteria for this condition have not yet been established. METHODS: A systematic literature review revealed 61 published cases with posterior tibial tendon dislocation in 36 reports, including eight (12 patients) in French and five (7 patients) in German. We add one more case, which was complicated by a longitudinal tibial tendon tear and a lateral talar dome osteochondral lesion. Fifty-nine cases were descriptively analysed regarding initial injury, subjective symptoms, clinical presentation and findings on different imaging modalities. Treatment and outcome were additionally evaluated. RESULTS: 58.5% of the initial injuries were induced by sport. Initially most cases were misdiagnosed (53.1%). 35.6% of the patients felt a recurrent snapping phenomenon at the medial ankle. Physical examination exhibited a cord-like structure over the medial malleolus in 58.6%, and a posterior tibial tendon (sub)luxation could be provocated in 54.2%. MRI, ultrasound and plain radiography (medial malleolar chip fracture) detected specific findings in 75.0%, 66.7% and 14.7%, respectively. Surgery was done in 83.1% of the patients using varying techniques. The authors judged the treatment result as excellent or asymptomatic in 80%, as good in 12% and as fair or moderate in 8% of the patients. CONCLUSIONS: Posterior tibial tendon dislocation occurs more frequently than was previously thought. Misdiagnosis can be avoided, if the surgeon is aware of the condition and combines findings from history, physical investigation and imaging modalities.

The natural history of osteochondral lesions in the ankle.

Most osteochondral lesions (defects) of the talar dome are caused by trauma, which may be a single event or repeated, less intense events (microtrauma). A lesion may heal, remain asymptomatic, or progress to deep ankle pain on weight bearing, prolonged joint swelling, and the formation of subchondral bone cysts. During loading, compression of the cartilage forces water into the microfractured subchondral bone. The increased flow and pressure of fluid in the subchondral bone can cause osteolysis and the slow development of a subchondral cyst. The pain does not arise from the cartilage lesion but most likely is caused by repetitive high fluid pressure during walking and a concomitant decrease in pH produced by osteoclasts, which sensitize the highly innervated subchondral bone. Prevention of further degeneration depends on several factors, including the repair of the subchondral bone plate and the correct alignment of the ankle joint.

Osteochondral Lesions of the Talar Dome.

Osteochondral lesion of the talar dome (OCLT) can be a devastating injury that affects mobility. Etiology of these lesions is debated but trauma seems the most supported etiology. Diagnosis of lesions is based on imaging. Conservative management, including weight-bearing restrictions, physical therapy, and supportive measures, often is first-line treatment. Nonsurgical modalities have mixed results and surgical measures often are necessitated for symptom relief. Surgical treatments vary in invasiveness and often are dictated by OCLT size. Studies show patient satisfaction increases substantially after having these procedures performed after failing nonsurgical measures. Results are encouraging, although thorough work-up and discussion should be undertaken.

Bilateral osteochondral lesions of the talus.

BACKGROUND: Osteochondral lesions of the talus (OLT) are relatively uncommon but may be a cause of significant pain and disability. Although the majority of patients have an osteochondral lesion of the talus that is unilateral, bilateral involvement has been reported in 10% to 25% of cases. In addition, factors that cause one side to be symptomatic and the contralateral side to be asymptomatic have never been evaluated. MATERIALS AND METHODS: A database containing all patients at our institution with an OLT has been maintained for the past 23 years. This was reviewed and patients with bilateral involvement identified. A chart review was performed to determine location and size of the OLT, which were symptomatic, associated with trauma, and required surgery. RESULTS: Between 1984 and 2007, 526 patients with an OLT were seen. Fifty-two patients had bilateral OLT, for an overall bilateral incidence of 10%. Of these, 16 patients required no surgery (Group 1), 31 required only unilateral surgery (Group 2), and five required bilateral surgery (Group 3). 88% of the OLT were located medially. Symptomatic talar lesions were significantly larger compared to asymptomatic OLT (p < 0.01). Of those that required only unilateral surgery, the size of the OLT eventually requiring surgery was significantly larger (p < 0.01). CONCLUSION: The overall incidence of bilateral involvement was 10%. A majority of patients with bilateral involvement had the OLT located on the medial side. A larger surface area appeared to be related to the presence of symptoms and the need for surgery.

Osteochondrosis juvenilis of the medial malleolar epiphysis.

Osteochondrosis juvenilis is caused by a dysfunction of endochondral ossification. Several epiphyses and apophyses can be affected, but osteochondrosis juvenilis of the medial malleolus has not been reported. We describe a 12-year-old boy with bilateral pes planovalgus who was affected by this condition. Conservative management was successful. The presentation, aetiology and treatment are described and the importance of including it in the differential diagnosis is discussed.

Osteochondral lesions of the talus.

Osteochondral lesions of the talus can present as a late complication of ankle injuries. As the talus is largely covered by articular cartilage, it has a limited ability for repair. Early and accurate diagnosis is important as talar integrity is required for optimal function of the ankle. The common presentation is chronic ankle pain with a history of ankle trauma. Conservative treatment involving a period of casting and non-weight-bearing is recommended for acute, non-displaced osteochondral lesions. Surgical management is recommended for unstable lesions or failed conservative management.

[Lumbosacral pain syndrome in sportsmen and ballet-dancer (diagnostic algorithm)].

There is presented an experience of the examination of 517 cases including sportsmen and ballet dancers, 15-45 olds, suffering from low back pain syndrome. 265 patients were diagnosed with osteochondrosis, 105 cases--with spondylolis, 92--with facet syndrome, and 55 cases--with pelvic ligaments ligamentopathia. Based upon the analysis of the results of examination diagnostic algorithm and differential diagnostics of these diseases were developed. The use of the proposed algorithm in patients with dissimilar variants of low back pain syndrome showed its informational content. It permits to make a right diagnosis and apply an adequate therapeutic approach.

Non-Small Cell Lung Carcinoma: Clinical Reasoning in the Management of a Patient Referred to Physical Therapy for Costochondritis.

Background and Purpose: Chest pain, a frequent complaint for seeking medical care, is often attributed to musculoskeletal pathology. Costochondritis is a common disorder presenting as chest pain. Initial physical therapist examination emphasizes red flag screening. Reexamination throughout the episode of care is critical, particularly when patients are not progressing and/or in the presence of complex pain presentations. The purpose of this case report is to describe the clinical reasoning process in the management of a patient referred to physical therapy with a medical diagnosis of costochondritis. Case Description: A 59-year-old woman presented with a 5-month history of left-sided chest pain that had progressed to include the cervical and shoulder regions. She reported multiple psychosocial stressors; a depression screen was positive. She reported a history of asthma and smoking and improvement in recent fatigue, coughing, dyspnea, and sweating. At the initial visit, shoulder, cervical, and thoracic active and passive range of motion and joint mobility testing reproduced her pain. Allodynia was present throughout the painful areas in the left upper quarter. Outcomes: The patient demonstrated improvement over 30 days (4 visits). On her fifth visit (day 35), she reported an exacerbation of her chest and upper extremity pain and noted increased fatigue, sweating, dyspnea, and loss of appetite. Even though her pain was again reproduced with musculoskeletal testing, the physical therapist contacted the patient's physician regarding the change in presentation. A subsequent chest computed tomography scan revealed a non-small cell lung adenocarcinoma. Discussion: Cancer can masquerade as a musculoskeletal condition. This case highlights the importance of screening, clinical reasoning, and communication throughout the episode of care, particularly in the presence of chronic pain and psychosocial stressors.

Outcome of osteochondral autograft transplantation for type-V cystic osteochondral lesions of the talus.

The treatment of osteochondral lesions of the talus has evolved with the development of improved imaging and arthroscopic techniques. However, the outcome of treatment for large cystic type-V lesions is poor, using conventional grafting, debridement or microfracture techniques. This retrospective study examined the outcomes of 50 patients with a cystic talar defect who were treated with arthroscopically harvested, cored osteochondral graft taken from the ipsilateral knee. Of the 50 patients, 45 (90%) had a mean good to excellent score of 80.3 (52 to 90) in the Karlsson-Peterson Ankle Score, at a mean follow-up of 36 months (24 to 83). A malleolar osteotomy for exposure was needed in 26 patients and there were no malleolar mal- or nonunions. One patient had symptoms at the donor site three months after surgery; these resolved after arthroscopic release of scar tissue. This technique is demanding with or without a malleolar osteotomy, but if properly performed has a high likelihood of success.

Arthroscopic Management of Osteochondral Lesions of the Talus.

Osteochondral fractures of the ankle are typically caused by traumatic injuries of the ankle. Repetitive trauma can lead to further cartilage damage with subsequent increasing size of the lesion, ultimately leading to severe cartilage disorder and degenerative arthritis of the ankle. Arthroscopic bone marrow stimulation has been shown to be a highly successful option for patients with small osteochondral lesions. Studies show a higher failure rate for larger lesions and cystic changes that disrupt the subchondral plate. The threshold size seems to be 150 mm(2).

Equol suppresses inflammatory response and bone erosion due to rheumatoid arthritis in mice.

Rheumatoid arthritis (RA) is a chronic and systemic autoimmune inflammatory disease. Typical pathological findings of RA include persistent synovitis and bone degradation in the peripheral joints. Equol, a metabolite of the major soybean isoflavone daidzein, shows superior bioactivity than other isoflavones. We investigated the effects of equol administration on inflammatory response and bone erosion in mice with collagen-induced arthritis (CIA). The severity of arthritis symptoms was significantly low in the equol-administered CIA mice. In addition, equol administration improved the CIA-induced bone mineral density decline. In the inflamed area of CIA mice, equol administration suppressed the expression of interleukin-6 and its receptor. Furthermore, equol reduced the expression of genes associated with bone formation inhibition, osteoclast and immature osteoblast specificity and cartilage destruction. These results suggest that equol suppresses RA development and RA-induced bone erosion by regulating inflammation and bone metabolism.

Arthroscopic assessment for intra-articular disorders in residual ankle disability after sprain.

BACKGROUND: After ankle sprain, there can be many causes of disability, the origins of which cannot be determined using standard diagnostic tools. HYPOTHESIS: Ankle arthroscopy is a useful tool in identifying intra-articular disorders of the talocrural joint in cases of residual ankle disability after sprain. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: The authors gathered the independent diagnostic results of physical examination, standard mortise and lateral radiography, stress radiography of the talocrural joint, and magnetic resonance imaging for 72 patients with residual ankle disability lasting more than 2 months after injury (mean, 7 months after injury). They performed arthroscopic procedures and compared the double-blind results. RESULTS: In all cases, the arthroscopic results matched those of other means of diagnosis. In 14 cases, the arthroscopic approach exceeded the capabilities of the other methods. Including duplications, 39 patients (54.2%) had anterior talofibular ligament injuries, 17 patients (23.6%) had distal tibiofibular ligament injuries, 29 patients (40.3%) had osteochondral lesions, 13 patients (18%) had symptomatic os subfibulare, 3 patients (4.2%) had anterior impingement exostosis, and 3 patients (4.2%) had impingement due to abnormally fibrous bands. There were only 2 cases in which the cause of symptoms could not be detected by ankle arthroscopy, compared with 16 cases in which the cause of disability could not be detected using standard methods. In 3 cases (17.6%) of distal tibiofibular ligament injuries, 8 cases (27.6%) of osteochondral lesions, and all 3 cases (100%) of impingement of an abnormal fibrous band, ankle arthroscopy was the only method capable of diagnosing the cause of residual ankle pain after a sprain. CONCLUSION: The present results suggest that arthroscopy can be used to diagnose the cause of residual pain after an ankle sprain in most cases that are otherwise undiagnosable by clinical examination and imaging study.

Prospective study on diagnostic strategies in osteochondral lesions of the talus. Is MRI superior to helical CT?

Our aim in this prospective study was to determine the best diagnostic method for discriminating between patients with and without osteochondral lesions of the talus, with special relevance to the value of MRI compared with the new technique of multidetector helical CT. We compared the diagnostic value of history, physical examination and standard radiography, a 4 cm heel-rise view, helical CT, MRI, and diagnostic arthroscopy for simultaneous detection or exclusion of osteochondral lesions of the talus. A consecutive series of 103 patients (104 ankles) with chronic ankle pain was included in this study. Of these, 29 with 35 osteochondral lesions were identified. Twenty-seven lesions were located in the talus. Our findings showed that helical CT, MRI and diagnostic arthroscopy were significantly better than history, physical examination and standard radiography for detecting or excluding an osteochondral lesion. Also, MRI and diagnostic arthroscopy performed better than a mortise view with a 4 cm heel-rise. We did not find a statistically significant difference between helical CT and MRI. Diagnostic arthroscopy did not perform better than helical CT and MRI for detecting or excluding an osteochondral lesion.
