Blastomycotic Osteomyelitis: An Unusual Cause of Hand Swelling.

Isolated blastomycosis hand infections are extremely rare, and are often clinically unsuspected, leading to delays in clinical diagnosis. Conclusive diagnosis often necessitates fungal cultures and histopathological demonstration of budding yeasts in tissues. In this report, we describe the rare occurrence of isolated blastomycotic hand infection, without any other organ involvement, in a 42-year-old male patient. Analyzing tissue specimens with frozen section has been shown in the past to demonstrate granulomatous inflammation and yeast forms of the organism; however, as demonstrated in this patient, the presence of pseudoepitheliomatous cells may deceptively appear as malignant, causing substantial concern and anxiety. Definitive diagnosis often necessitates fungal culture and histopathological examination with special fungal stains including polymerase chain reaction for speciation.

Ipsilateral Rupture of Quadriceps Tendon with Distal Tibia Fracture: A Case Report and Review of the Literature.

Traumatic rupture of the quadriceps tendon by itself is not an uncommon clinical condition. However, its association with concurrent ipsilateral closed distal tibia oblique fracture is exceedingly rare with only one previously reported case in English literature. The dual diagnosis of this atypical combination of injury may be masked by pain and immobilization of the more obvious fracture and may be missed, unless the treating physician maintains a high index of suspicion. Suprapatellar knee pain with or without a palpable gap in the quadriceps tendon and inability to straight leg raise in the setting of a distal tibia fracture should raise concern, but if initial treatment employs a long-leg splint the knee symptoms may be muted. In this report, we describe this unusual combination of injury in a 67-year-old male patient who sustained a trivial twisting injury to the leg. The aim of this report is to raise awareness and emphasize the importance of thorough and repeated clinical examinations in the presence of distracting injuries. Despite the complexity of the problem, standard techniques for quadriceps tendon repair using transpatellar bone tunnels following locked intramedullary rodding of the tibia fracture may lead to optimal outcomes.

Preliminary trauma radiographs misrepresent pubic diastasis injuries.

The goal of this study was to evaluate the role of portable primary trauma survey radiographs in the evaluation and management of anteroposterior (AP) compression pelvic injuries. A retrospective analysis was conducted at a level I academic trauma center. Twenty-seven adults with AP compressive class pelvic ring injuries who received both portable pelvic radiographs and pelvic computed tomography (CT) imaging in an unbound pelvic state were included. Three orthopedic surgeons performed independent measurements of diastasis on portable pelvic radiographs and coronal pelvic CT reconstructions. Measurement techniques were standardized among observers and were repeated after 8 weeks to assess intraobserver reliability. Nonoperative vs operative treatments were correlated with the initial magnitude of pelvic injury on CT and portable radiographic images. Independent measurements of diastasis on both radiographs and CT scans showed excellent intraobserver reliability (average correlation coefficient, 0.986) and interobserver reliability (average correlation coefficient, 0.979). Compared with diastasis measurements on CT scans, portable pelvic radiographs overestimated diastasis by an average of 49%, or 12.6 mm (P<.0001; 95% confidence interval, 9.6-15.6). Portable pelvic films were less precise than standard pelvic radiographs in measuring the size of femoral head controls (R(2)=0.919 vs 0.759; P=.004). In 12 of the 27 patients evaluated, radiographic indications for operative pelvic fixation were met by portable radiographs but not CT scans, and 11 of these patients ultimately underwent operative fixation. Portable AP pelvic radiographs may distort and exaggerate pelvic bony injuries, especially those involving anterior pelvic structures. Surgeons should use caution when making management decisions based on preliminary portable pelvic radiographs.
