Nikhil Sharma, Ahmed El Refaiy, T F Sibly
We report outcomes of using GraftJacket to repair massive rotator-cuff-tears. Twenty patients with a mean age of 64.6y over 12-month duration were reviewed. Two patients had a single GraftJacket repair (group1), whilst 18 had the GraftJacket sheet doubled (group2). Pre and post oxford shoulder scores (OSS) and patient related outcome measures were evaluated. A statistically significant improvement of OSS was demonstrated in-group 2 from a mean of 22 to 45.5 (p < 0.00148) over a follow up of 18 months...

Background: Currently, correction of the first intermetatarsal angle associated with hallux valgus is done using two main categories of surgeries either a distal or a proximal first metatarsal osteotomy. The osteotomy-sparing technique using TigthRope ®device was developed to manage hallux valgus avoiding osteotomy complications. Our hypothesis was that osteotomy sparing technique using TightRope® implant would be suitable for moderate hallux valgus in young adult patients with strong larger bones giving good results with minimal complications...

Femoral shaft fracture is the commonest major pediatric orthopedic injury requiring hospitalization. Controversy persists regarding management of femoral fractures in the patients aged between 5-15 years. 11 patients were followed up for the mean period of 12 months and evaluated using Flynn's criteria. All the fractures united between 8-12 weeks. 3 patients had knee stiffness, 1 patient had shortening > 2 cm and 1 had superficial infection. We conclude that TENs is simple, rapid & effective treatment for displaced pediatric femoral shaft fractures between 5-15 years of age with very less complication rate...

One-hundred and three patients with intertrochanteric hip fractures as classified by the OTA 2007 system underwent fixation using the telescoping AOS Galileo lag screw system and ES Nail (a long IM nail). Thirty-one patients (76%) were female and ten (24%) were male, with an average age of 75.70 ± 11.3 years at date of surgery. At final follow-up 21 (53%) patients returned to their pre-fracture ambulatory status, 20 (47%) had a reduction in ambulatory status, and no patients were confined to a wheel chair...

Idiopathic toe walking (ITW) is a pathological gait pattern in which children walk on their tip toes with no orthopedic or neurological reason. Physiological characteristics of the gastrocnemius muscles, the Achilles tendon, and the foot of toe walkers differ from subjects with a plantigrade walking pattern. McArdle's disease is characterized by the inability to break down muscle glycogen. It is an autosomal-recessive condition, characterized by low exercise tolerance, muscular atrophy at the shoulder girdle, episodes of myoglobinuria after vigorous physical activities and the occurrence of the second wind phenomenon...

Antibiotic-impregnated calcium sulfate (AICS) beads have been used for prevention and treatment of periprosthetic joint infections. We evaluated post-operative complications following the use of AICS beads. 56 patients undergoing complex primary or revision hip or knee arthroplasty received antibiotic calcium sulfate beads. Primary outcomes were wound complication rates. Secondary outcomes included reoperation and reinfection rates. One case (1.7%) of persistent wound drainage occurred requiring surgical irrigation and a poly-exchange...

This study used the National Surgical Quality Improvement Program to evaluate octogenarians who underwent total shoulder arthroplasty (TSA). Specifically, we evaluated: (1) patient demographics; (2) perioperative factors; and (3) 30-day postoperative complications. Compared to controls, the octogenarians had more females, white patients, lower BMIs, fewer smokers, less functionally independent, higher ASA scores, shorter operative times, and longer LOS. Octogenarians had greater odds for developing any (OR = 2...

Background: When compared to total hip arthroplasty (THA), hip resurfacing arthroplasty (HRA) is usually undertaken in younger, more active patients with hip osteoarthritis. Previous research has noted that patients are able to return to pre-operative activity levels, with many even increasing their activity post HRA, but patterns in post-operative recovery have been less well investigated. Materials and Methodology: A randomised controlled trial dataset was analysed to explore activity levels attained after HRA...

ACL injury can be clinically diagnosed prior to imaging, and therefore understanding any symptomatology differences between age-groups and genders is critical. Data gathered from 341 patients with ACL injuries over six years showed no gender-based difference in ability to continue playing sport post-injury. Fewer males required crutches (37.2% vs. 49.5%, p = 0.04) and more males returned to sports prior to treatment (24.4% vs. 14.1%, p = 0.04). There was no age based difference in play continuation post-injury, however more elderly patients fell post-injury (<30 y: 91...
