Comparative StudyBilateral transfemoral/transtibial amputations due to battle injuries: a comparison of Vietnam veterans with Iraq and Afghanistan servicemembers.
Multiple limb loss from combat injuries has increased as a proportion of all combat-wounded amputees. Bilateral lower-extremity limb loss is the most common, with bilateral transfemoral amputations being the most common subgroup followed by bilateral amputations consisting of a single transfemoral amputation and a single transtibial amputation (TFTT). With improvements in rehabilitation and prostheses, we believe it is important to ascertain how TFTT amputees from the present conflicts compare to those from the Vietnam War. ⋯ Participants with TFTT limb loss from both conflicts reported similar scores for QoL and health status, although those from OIF/OEF reported better function and use of prosthetic devices. It is unclear whether the improved function is from age-related changes or improvements in rehabilitation and prosthetics. Some areas of future research might include longitudinal studies of those with limb loss and assessments of physical function of older individuals with limb loss as the demographics shift to where this group of individuals becomes more prominent.

What are the patterns of prophylactic postoperative oral antibiotic use after foot and ankle surgery?
The CDC estimates 23% of healthcare-associated infections to be surgical site infections, with alarming prevalence of antibiotic-resistant organisms. While there is consensus regarding preoperative prophylaxis, orthopaedic surgeons' use of prophylactic postoperative oral antibiotics is less defined. ⋯ Surgeons' reported use of prophylactic postoperative oral antibiotics after elective foot or ankle surgery was common, without demographic association. Commonalities were identified in antibiotic regimen and personal indications for this practice. Comparative clinical studies are warranted to elucidate the efficacy of prophylactic postoperative oral antibiotics and establish evidence-based guidelines for their use.

Observational StudyCan an integrated orthotic and rehabilitation program decrease pain and improve function after lower extremity trauma?
Patients with severe lower extremity trauma have significant disability 2 years after injury that worsens by 7 years. Up to 15% seek late amputation. Recently, an energy-storing orthosis demonstrated improved function compared with standard orthoses; however, the effect when integrated with rehabilitation over time is unknown. ⋯ We found this integrated orthotic and rehabilitation initiative improved physical performance, pain, and patient-reported outcomes in patients with severe, traumatic lower extremity deficits and that these improvements were sustained for > 2 years after injury. Efforts are underway to determine whether the Return to Run clinical pathway with the Intrepid Dynamic Exoskeletal Orthosis (IDEO) can be successfully implemented at additional military centers in patients > 2 years from injury while sustaining similar improvements in patient outcomes. The ability to translate this integrated orthotic and rehabilitation program into the civilian setting is unknown and warrants further investigation.

Comparative StudyDoes fracture affect the healing time or frequency of recurrence in a simple bone cyst of the proximal femur?
Studies have focused on intramedullary nailing of femoral simple bone cysts but have not clarified the recurrence frequency or management of recurrent cysts. In particular, the affect of pathologic fractures on cyst healing, recurrence, and complications of treatment have not been reported. ⋯ Whether a pathologic fracture had occurred before surgical treatment, intramedullary nailing of femoral simple bone cysts resulted in reliable healing, and the frequency of recurrence did not differ. Because this was a retrospective study, the optimal treatment for recurred cysts after intramedullary nailing should be further investigated through a comparative or prospective study.

Benefit of cup medialization in total hip arthroplasty is associated with femoral anatomy.
Medialization of the cup with a respective increase in femoral offset has been proposed in THA to increase abductor moment arms. Insofar as there are potential disadvantages to cup medialization, it is important to ascertain whether the purported biomechanical benefits of cup medialization are large enough to warrant the downsides; to date, studies regarding this question have disagreed. ⋯ Cup medialization with compensatory increase of the femoral offset may be particularly effective in patients with less femoral antetorsion. However, cup medialization must be balanced against its tradeoffs, including the additional loss of medial acetabular bone stock, and eventual proprioceptive implications of the nonanatomic center of rotation and perhaps joint reaction forces. Clinical studies should better determine the relevance of small changes of moment arms on function and joint reaction forces.
