Background: Previous studies investigating the windmill softball pitch have focused primarily on shoulder musculature and function, collecting limited data on elbow and forearm musculature. Little information is available in the literature regarding the forearm. This study documents forearm muscle electromyographic (EMG) activity that has not been previously published.

Purpose: Elbow and upper extremity overuse injuries are on the rise in fast-pitch softball pitchers. This study attempts to describe forearm muscle activity in softball pitchers during the windmill softball pitch. Overuse injuries can be prevented if a better understanding of mechanics is defined.

Study Design: Descriptive laboratory study.

Methods: Surface EMG …

Controlled Laboratory Comparison Study Of Motion With Football Equipment In A Destabilized Cervical Spine: Three Spine-Board Transfer Techniques, Mark L. Prasarn, Marybeth Horodyski, Matthew J. Dipaola, Christian P. Dipaola, Gianluca Del Rossi, Bryan P. Conrad, Glenn R. Rechtine Ii

Background: Numerous studies have shown that there are better alternatives to log rolling patients with unstable spinal injuries, although this method is still commonly used for placing patients onto a spine board. No previous studies have examined transfer maneuvers involving an injured football player with equipment in place onto a spine board.

Purpose: To test 3 different transfer maneuvers of an injured football player onto a spine board to determine which method most effectively minimizes spinal motion in an injured cervical spine model.

Study Design: Controlled laboratory study.

Methods: Five whole, lightly embalmed cadavers were fitted with shoulder pads and …

Expandable Total Humeral Replacement In A Child With Osteosarcoma, Eric R. Henderson, Jidi Gao, John Groundland, Odion Binitie, G. Douglas Letson

Case. A right-handed 8-year-old female patient presented with a conventional, high-grade osteosarcoma involving her right humerus; through-shoulder amputation was recommended. After consultation, total humerus resection with expandable, total humeral endoprosthesis reconstruction was performed with a sleeve to encourage soft-tissue ingrowth. At three-year follow-up she has received one lengthening procedure and her functional scores are excellent. Conclusion. Total humeral resection and replacement in the pediatric population are rare and although early reports of expandable total humeral endoprosthesis outcomes demonstrate high failure rates, this patient’s success indicates that expandable total humeral replacement is a viable option.
