ABSTRACT

Femoral neck stress fractures (FNSFs) are increasingly common, particularly in military training. The usual mode of classifying these injuries is based on the involvement of the compression or tension side of the femoral neck; however, this may oversimplify and fail to address factors such as the orientation of the fracture line. We present a novel subtype of a compression-sided FNSF affecting the subcapital femoral neck and report the treatment outcomes in a military trainee population. A retrospective analysis of patients with a subcapital, compression-sided FNSF was identified from a single U.S. Army basic trainee installation. Radiographic evaluation as well as treatment outcomes associated with the ability to complete military training were reported. A total of three patients with a subcapital compression-sided FNSF were identified in a military trainee population, accounting for 10% of all FNSFs that developed over a 3-month period. Of these individuals, one was treated operatively while the other two were treated non-operatively. Overall, one patient was able to return to and successfully complete military training.

ABSTRACT

BACKGROUND: Cast removal can be associated with considerable noise exposure, especially impacting the pediatric patient and provider. Although noise generation from cast saws has been deemed safe by the U.S. Occupational Safety and Health Administration and the U.S. Centers for Disease Control and Prevention standards, there are no current studies on the effects of cast material on noise levels generated. METHODS: A simulated casting model utilizing plaster, fiberglass, and plaster with fiberglass overwrapping was used for experimental testing. Four different casting conditions were tested, with 5 samples in each group. Samples were tested using 2 different cast saws: a standard cast saw and a quiet saw. Each saw was used for 30 seconds of continuous cutting for each sample, measuring peak, mean, and minimum sound levels in decibels with sound level meters. Noise levels were measured at 18, 36, and 72 in (20, 91, and 183 cm) from the saw, comparing saw and cast types against ambient noise and baseline cast-saw noises. Between-group comparisons were performed using univariate analyses. RESULTS: Mean noise generation differed between casting materials, with plaster material demonstrating significantly greater noise levels than fiberglass casts at all distances for each saw type. Increasing fiberglass thickness significantly increased the mean noise levels with standard (18-in distance for 10 and 5 ply: 87.4 and 85.8 dB; p = 0.0004) and quiet cast saws (78.3 and 76.1 dB; p = 0.041. Additionally, the quiet cast saw provided a 5.7 to 10.6 dB reduction in mean and peak noise levels, varying by casting material and distance. CONCLUSIONS: Occupational noise exposure can be mitigated with the use of fiberglass casting material that is not >5 ply in thickness, with a quiet cast saw for removal. The use of a quiet cast saw substantially decreased noise exposure to patients and staff members over standard orthopaedic cast saws.

ABSTRACT

CASE: A 2.5-year-old male child presented to the clinic for evaluation of left wrist popping. Ten months earlier, he sustained a closed left both-bone forearm fracture (BBFF) treated with reduction and casting. His clinical course was complicated by redisplacement requiring secondary manipulation and casting before osseous union. His parents reported wrist popping with active motion in the setting of a 20° apex volar malunion of the midshaft radius. He has been treated with observation and monitoring of deformity remodeling. CONCLUSION: Distal radioulnar joint instability is a potential complication of malunited BBFF, even in a pediatric population. Residual deformity, especially in the radius, should prompt clinical follow-ups after osseous union to assess functional recovery and deformity remodeling.
