W C Lee Lhj Wee

Malays Orthop J 2019 Mar;13(1):42-44

Department of Orthopaedic Surgery, Tan Tock Seng Hospital, Singapore.

We present a unique case of tibial post fracture of a posterior-stabilised total knee arthroplasty (PS-TKA) using highly crosslinked polyethylene (HXLPE) in the unafflicted limb of a patient who had poliomyelitis. The tibial post is an upright structure perpendicular to the PE insert articular surface which articulates with the cam of the femoral component to prevent excessive posterior translation of the tibia. We explore the choice of PS polyethylene (PE) inserts in patients with neuromuscular disorders (NMD). Read More

Outcome of Islanded Gastrocnemius Musculocutaneous Flap in Orthopaedic Practice.

Malays Orthop J 2019 Mar;13(1):25-29

Department of Surgery, International Islamic University of Malaysia, Kuantan, Malaysia.

Large wounds in the leg require combination of local flaps or free flap for wound coverage. Gastrocnemius musculocutaneous flap (GMCF) allows a large wound to be covered by a single local flap. However, the conventional GMCF is often associated with donor site morbidity where the exposed soleus raphe causes poor uptake of the skin graft. Read More

Does Femoral Notching During Total Knee Arthroplasty Influence Periprosthetic Fracture. A Prospective Study.

J Arthroplasty 2019 Feb 27. Epub 2019 Feb 27.

Department of Orthopaedics, Sparsh Hospitals, Bangalore, India.

Background: Notching of the anterior femoral cortex during total knee arthroplasty (TKA) has been attributed to cause supracondylar fractures of the femur. Anatomic variations in the femur bone in different races make notching inevitable when standard designs of prostheses are used. The objective of this study is to determine the prevalence of notching when a PFC Sigma knee was used in an Indian population sample using the anterior referencing system and to assess the frequency of femoral shaft fractures in these cases.

Tribble, A. C. Weintrob, Infectious Disease Clinical Research Program, Department of Preventive Medicine and Biostatistics, Uniformed Services University of the Health Sciences, Bethesda, MD, USA B. K. Potter, L R. Lewandowski, Department of Surgery, Uniformed Services University of the Health Sciences-Walter Reed National Military Medical Center, Bethesda, MD, USA A. C. Weintrob, The Henry M. Jackson Foundation for the Advancement of Military Medicine Inc, Bethesda, MD, USA; and Walter Reed National Military Medical Center, Bethesda, MD, USA M. Krauss, Westat, Rockville, MD, USA.

Background: During recent wars, 26% of combat casualties experienced open fractures and these injuries frequently are complicated by infections, including osteomyelitis. Risk factors for the development of osteomyelitis with combat-related open tibia fractures have been examined, but less information is known about recurrence of this infection, which may result in additional hospitalizations and surgical procedures.

Questions/purposes: (1) What is the risk of osteomyelitis recurrence after wartime open tibia fractures and how does the microbiology compare with initial infections? (2) What factors are associated with osteomyelitis recurrence among patients with open tibia fractures? (3) What clinical characteristics and management approaches are associated with definite/probable osteomyelitis as opposed to possible osteomyelitis and what was the microbiology of these infections?

Methods: A survey of US military personnel injured during deployment between March 2003 and December 2009 identified 215 patients with open tibia fractures, of whom 130 patients developed osteomyelitis and were examined in a retrospective analysis. Read More

Restoring Condylar Width: Radiographic Relationship Between the Lateral Tibial Plateau and Lateral Femoral Condyle in Normal Adult Knees.

J Orthop Trauma 2019 Apr;33(4):180-184

Department of Orthopaedic Surgery, Keck School of Medicine of USC, Los Angeles, CA.

Objectives: We hypothesized that a constant radiographic relationship exists between the lateral tibial and femoral condyles and that no side-to-side variation exists.

Methods: We reviewed anteroposterior x-rays of 217 uninjured adults ages 18-65, Included 109 unilateral and 108 bilateral radiographs with no or minimal osteoarthrosis (Kellgren-Lawrence grades 0-1). The perpendicular distance between the lateral-most margins of the tibial plateau articular surface (A) and the lateral femoral epicondyle (B) and the lateral femoral condyle articular surface (C) was measured in millimeters (mm).

Assessing the performance of motorcyclists' impact protectors in simulated ATD knee and shoulder impacts.

Traffic Inj Prev 2019 19;20(2):169-173. Epub 2019 Mar 19.

b Neuroscience Research Australia, School of Medical Science , University of New South Wales , Randwick , New South Wales , Australia.

Objective: Fractures are a common injury among motorcycle riders and can have serious health implications. Impact protection (IP) has been designed to help prevent fractures, yet there are conflicting opinions as to whether this IP does in fact help prevent fractures in real-world crashes. This work aimed to (1) use simulated dummy impacts to examine whether existing types of IP could reduce the force transferred to the underlying bone to below fracture tolerance levels and (2) investigate whether current European Standard (EN 1621-1) test procedures for impact protectors designed for motorcyclists are sufficient to ensure fracture protection.
