Bone Biopsies

Microbiological cultures of per-wound bone biopsies have shown a lack of correlation and a high rate of false-negative results when compared with bone biopsy cultures in diabetic foot osteomyelitis. The selection of samples from the area of active osteomyelitis, which contains a complete census of the microorganisms responsible for the infection, is essential to properly guide antimicrobial treatment. We aimed to comparatively evaluate the quantitative and qualitative cultures taken from different areas, in metatarsal heads resected for osteomyelitis. For this purpose, we consecutively selected 13 metatarsal heads from 12 outpatients with plantar ulcers admitted to our diabetic foot unit. Metatarsal heads were divided transversally into 3 portions: plantar (A), central (B), and dorsal (C), and the 39 resulting samples were cultured. Qualitative and quantitative microbiological analysis was performed, and the isolated species and bacterial load, total and species specific, were compared between the 3 metatarsal bone segments. The primary outcome of the study was the bacterial diversity detected in the different bone sections. Cultures were positive in 12 of the 13 included metatarsal heads (92%). A total of 34 organisms were isolated from all specimens. Ten of the 12 cultures (83%) were polymicrobial. Ten of the 13 metatarsal heads (77%) had identical microbiological results in each of the 3 bone sections. The largest number of microorganisms was found in the central section. The overall concordance between sections was 91%. The predominant microorganisms were coagulase-negative staphylococci (41%). Statistical differences were not found in the bioburden between sections (range 3.25-3.41 log10 colony-forming unit/g for all sections; P = .511). The results of our study suggest that microorganisms exhibit a high tendency to spread along the metatarsal bone and that the degree of progression along the bone is species dependent. The central portions of metatarsal bones tend to accumulate a higher diversity of species. Thus, we recommend this area of bone for targeted biopsy in patients with suspected osteomyelitis.

The Difference

Objective. To evaluate the involvement of the bursa located next to the head of the 5th metatarsal bone in patients with psoriatic arthritis (PsA) in comparison with the other seronegative spondyloarthritis (SpA).Methods. All patients with PsA seen during a period of 24 months were enrolled. The control group included healthy subjects and patients with the other SpA. All subjects underwent clinical and ultrasound (US) examination of the lateral surface of the 5th metatarsal.Results. 150 PsA patients (88 M; 62 F), 172 SpA (107 M; 65 F), and 95 healthy controls (58 M; 37 F) were evaluated. Based on clinical and US evaluation, bursitis was diagnosed in 17/150 (11.3%) PsA patients but in none of the SpA (P<0.0001) and healthy (P=0.0002) controls. In detecting bursitis, US was more sensitive than clinical examination, although the difference did not reach statistical significance (P=0.09).Conclusion. The bursa of the 5th metatarsophalangeal joint appears to be involved in PsA more frequently than by chance. If confirmed by other studies, this finding could be considered as a distinctive clinical sign of PsA, useful for differential diagnosis with the other SpA. In asymptomatic patients, US proved to be more sensitive in the detection of bursitis.

Stepwise Procedure

The aim of this study is to find basic quantitative geometric data that may contribute to the understanding of the etiology of hallux valgus. Embalmed specimens with existing hallux valgus (N = 39) were dissected; 28 variables were measured with a Vernier caliper gauge and toe goniometer. Correlations between pairs of independent variables were calculated. Linear dependency of the hallux angle, varus angle, and the width of the forefoot on a number of independent variables was analyzed by multiple linear regression. A least squares method and a stepwise procedure were used. The distance from the tendon of the flexor hallucis longus muscle to the head of the first metatarsal bone explains more than other variables the variation in hallux angle and width of the forefoot. A widened forefoot is significantly correlated with both hallux and varus angles. The interrelation of the predictor parameters illustrates the complicated hallux valgus phenomenon.

Background: Mixed results for functional outcomes and long-term fixation have been reported for first metatarsophalangeal arthroplasty. This prospective study was designed to evaluate the migration of the BioPro metatarsophalangeal-1 (MTP-1) joint hemiprosthesis with Roentgen stereophotogrammetric analysis (RSA). Migration patterns of the prosthesis, prosthesis-induced erosion of the metatarsal bone, and clinical outcomes were evaluated sequentially to 5 years postoperation (PO). Methods: Eleven female patients received the BioPro-1 hemiprosthesis. Prosthesis translation and metatarsal erosion were measured with RSA at immediately PO, 6 weeks, and 3, 6, 12, 36, and 60 months postoperatively. Clinical assessment was done by patient questionnaires. Results: RSA data of 9 patients were available for analysis. Median (range) number of markers used in RSA analysis, condition number, and mean error of markers around the prosthesis were 4 (3-7), 320 (208-862), and 0.13 (0.02-0.28), respectively. Progressive subsidence was seen up to 3 years PO (mean 2.1 mm, SE 0.32). Progressive metatarsal erosion was found from 1 year PO (mean 0.49 mm, SE 0.15). Pain, function, and quality scores improved after surgery and did not deteriorate at later follow-up moments. Conclusion: Model-based RSA of the BioPro-1 prosthesis shows nonstabilizing medial and distal translation and metatarsal erosion. Despite the measured migration and erosion, clinical outcomes improved and remained similar up to 5 years postoperation.
