[Surgical treatment of the Charcot foot : long-term results and systematic review]. / Operative Versorgung des Charcot-Fußes am Rückfuß : Langzeitergebnisse und systematischer Überblick.

BACKGROUND: Because of extensive bone loss and the associated complex instability and deformity of the feet, Charcot arthropathy or neuroosteoarthropathy is a challenge for the orthopedic surgeon. Ulcerations offer entry of various bacteria; thus, infections are a frequent serious issue and complication. The careful choice of treatment is not only very important for the correct alignment of the foot and the loading capacity, but also contributes significantly to the prevention of skin irritation or the healing of existing ulcers. Above all, chronic plantar ulcerations, caused by prominent exostoses or axial malalignments are almost untreatable without surgery. Because diagnosis requires an individual approach, no strict regimen of therapy has become established. OBJECTIVES: The major objective was to reduce the number of ulcerations and infections, and to minimize the risk of amputation. In addition, complications and comorbidities were determined. Tibio-calcaneal arthrodesis is a very frequently used surgical treatment option. Therefore, a special focus in the following article is on this method. MATERIALS AND METHODS: In a 12-year period (1999-2011), 43 patients (46 feet) suffering from Charcot foot were treated surgically. The following were used: triple, talo-navicular, subtalar, tibio-calcaneal arthrodesis and midfoot fusion bolts. The arthrodesis related to the hindfoot and tarsus and most commonly the tibio-calcaneal arthrodesis was applied. The reduction of load on the affected foot preoperatively and postoperatively by white-cast, Aircast walker shoe or other orthesis is essential in the treatment. For a long-term satisfactory outcome, an orthopedic custom-made shoe is indispensable after surgical treatment. RESULTS: After surgical treatment of 16 feet with ulcerations, 14 could be healed and only 2 suffered from complications, such as infections, nonunions, talus necrosis, and wound healing disorder. Revision was frequently necessary, although the majority of complications could be treated. In this population, three amputations could not be prevented. CONCLUSION: Even with strict aseptic techniques and years of experience in Charcot arthropathy, complications can occur, which can even lead to amputation. The early detection of the Charcot foot is the most important factor and helps to reduce morbidity and further complications. Co-morbid diseases (e.g., diabetes mellitus) need special care and optimal treatment, because they are often responsible for the poor surgical outcome. Finally, the ulceration rate and related complications, such as amputation, can be reduced by timely surgical treatment. Unfortunately, the progressive course of the disease often requires follow-up operations.

Dental Apical Inflammation Score (DAIS): Histopathological scoring for the evaluation of the apical inflammatory activity and local bone destruction.

OBJECTIVE: The purpose of this study was to evaluate 210 periapical lesions with a newly created Dental Apical Inflammation Score/DAIS with regard to their inflammatory cell infiltration, bone tissue, epithelium, bacteria and foreign material. STUDY DESIGN: Specimens were obtained from 51 different dental practices over a period of 11 months. These specimens were then sent in for histopathological routine diagnostics. RESULTS: The DAIS classified 81 cases of Type 1 (acute inflammation = low, chronic inflammation = low), 79 cases of Type 2 (acute inflammation = low, chronic inflammation = high), 46 cases of Type 3 (acute inflammation = high, chronic inflammation = low) and 4 cases of Type 4 (acute inflammation = high, chronic inflammation = high). Bone tissue was found in 141 cases, signs for bacterial osteitis in 49 cases, cyst epithelium in 40 cases and foreign material in 27 cases. In 210 cases, cyst epithelium was evident in 27.2 % of Type 1, 15.2 % of Type 2, 8.7 % of Type 3 and in 50 % of Type 4 (p = .019). The 141 cases containing bone tissue showed signs of bacterial osteitis in 16.1 % of Type 1, 29.8 % of Type 2, 77.8 % of Type 3 and in 100 % of Type 4 (p < .001). In 64 cases, Bacteria was evident in 30 % of Type 1, 25 % of Type 2, 55 % of Type 3 and in 100 % of Type 4 (p = .013). CONCLUSION: The DAIS could classify apical lesions with statistically significant differences. Bacterial osteitis in apical lesions was reported for the first time.

Mid-term follow-up of patients with hindfoot arthrodesis with retrograde compression intramedullary nail in Charcot neuroarthropathy of the hindfoot.

AIMS: Hindfoot arthrodesis with retrograde intramedullary nailing has been described as a surgical strategy to reconstruct deformities of the ankle and hindfoot in patients with Charcot arthropathy. This study presents case series of Charcot arthropathy patients treated with two different retrograde intramedullary straight compression nails in order to reconstruct the hindfoot and assess the results over a mid-term follow-up. PATIENTS AND METHODS: We performed a retrospective analysis of 18 consecutive patients and 19 operated feet with Charcot arthropathy who underwent a hindfoot arthrodesis using a retrograde intramedullary compression nail. Patients were ten men and eight women with a mean age of 63.43 years (38.5 to 79.8). We report the rate of limb salvage, complications requiring additional surgery, and fusion rate in both groups. The mean duration of follow-up was 46.36 months (37 to 70). RESULTS: The limb salvage rate was 16 of 19 limbs. Three patients had to undergo below-knee amputation due to persistent infection followed by osteomyelitis resistant to parenteral antibiotic therapy and repeated debridement. Complications including infection, hardware removal, nonunion, and persistent ulcers requiring further intervention were also observed. Postoperative functional scores revealed significant improvement compared with preoperative scores on American Orthopaedic Foot and Ankle Society (AOFAS) - Hindfoot scale, Foot Function Index (FFI), visual analogue scale (VAS), and Foot and Ankle Outcome Score (FAOS). CONCLUSION: The use of retrograde intramedullary compression nail results in good rates of limb salvage when used for hindfoot reconstruction in patients with Charcot arthropathy.
