Severely Deformed Extraarticular Fractures Of The Scapula: A Review, Sean B. Kuehn

UNM Orthopaedic Research Journal

Nonoperative treatment of severely deformed fractures of the scapula was historically common. However, the findings of newer research have challenged the notion that conservatively managing these fractures results in the most successful outcomes. In an attempt to possibly reveal important indicators for surgical treatment, I reviewed studies on scapula fractures involving scapular anatomy; associated injuries; technological advances that have helped with fracture evaluation; and treatment outcomes between nonsurgical and surgical methods. Although a universally accepted classification scheme of scapula fractures does not exist, use of 3D reconstruction with computed tomography can help define the level and category of fracture deformity. …

Treatment Of Full Circumferential Segmental Bone Loss Of The Tibia Resulting From Acute Traumatic Injuries And Complications: A Review, Gregory C. Strohmeyer

UNM Orthopaedic Research Journal

Full circumferential segmental bone loss of the tibia presents a challenge to orthopaedic surgeons. These open fractures often involve extensive soft-tissue damage, which can contribute to poor long-term outcomes even if the tibia is successfully reconstructed. Although amputation was historically used to treat full circumferential segmental bone loss of the tibia because of the severity of the injury, the development of new reconstruction procedures has provided the option of limb salvage techniques. I reviewed studies on treatment of traumatic tibia bone loss, focusing particularly on full circumferential bone loss of greater than 3 cm. Treatment options included amputation, allograft replacement, …

Open Reduction And Internal Fixation For Treatment Of Proximal Humerus Fractures: A Review, Heather K. Woodin

UNM Orthopaedic Research Journal

Fractures of the proximal humerus are common in older patients, and the incidence of these fractures in the United States is expected to notably increase with the aging population. Nonoperative procedures have been preferred in elderly patients with stable fracture patterns to avoid complications associated with osteoporotic bone. However, more complex and unstable fracture patterns often necessitate operative techniques to allow for more anatomical healing. Although proximal humerus fractures have been thoroughly examined, systemized, and studied, no clear method to choosing an appropriate surgical treatment or candidate has been accepted. I reviewed the role of the following factors on successful …

Survey Of Current Articles Published On Total Ankle Arthroplasty And Ankle Fusion, Tony G. Pedri, Richard A. Miller

UNM Orthopaedic Research Journal

In the United States, ankle fusion is more commonly performed than total ankle arthroplasty (TAA) for treatment of degenerative joint disease of the ankle. However, recent advances in implant design and technique have led to a renewed interest in research on TAA. To shed light on current research trends and limited data rather than examine the merits between both methods, we performed a PubMed search of studies on TAA and ankle fusion between January 1, 2009, and January 1, 2015, published in both the American edition of the Journal of Bone and Joint Surgery (JBJS) and Foot & Ankle International …

Third Extensor Compartment Disruption And The Biomechanics Of Thumb Extension, Christina Salas, Drew K. Newhoff, Zainab Cheema, Allison A. Richards, Deana M. Mercer, Amanda K. Medoro, Ahmed M. Afifi, Moheb S. Moneim, John M. Veitch

UNM Orthopaedic Research Journal

Background: Procedures involving release of the third dorsal wrist compartment have been thought to transpose the extensor pollicis longus (EPL) tendon from its anatomical position. Few studies, however, have reported on the effects this might have on function and mechanics of the thumb. We analyzed the impacts of intact extensor retinaculum, release of the third dorsal compartment, and removal of Lister’s tubercle on thumb extension.

Methods: A total of 15 fresh-frozen cadaveric upper extremities (eight male, seven female; mean age, 52 years; range, 38-59 years) were used. For each specimen, three phases of testing were analyzed: the extensor retinaculum was …

Isolated Traumatic Subscapularis Tear In A 12-Year-Old Male Gymnast: A Case Report, Katherine J. Gavin, Gehron P. Treme

UNM Orthopaedic Research Journal

Isolated avulsion fractures of the lesser tuberosity are rarely encountered in younger and older populations. However, because the tendon of the subscapularis insertion is stronger in skeletally immature individuals, isolated tears to the tendon occur more commonly in adults than children and adolescents. Most studies have been limited to case reports that mainly describe traumatic subscapularis tears in adolescent athlete-patients. We present a 12-year-old male gymnast who reported to our clinic with pain and weakness in the right shoulder at 2 months after the initial injury. We performed open repair with suture anchor fixation for treatment of an isolated subscapularis …

Severe Ischemia Of The Finger After Use Of Compressive Self-Adherent Wrap: Report Of Two Cases, Andrea B. Lese, Elizabeth A. Mikola, Deana M. Mercer

UNM Orthopaedic Research Journal

Use of Coban compressive self-adherent wraps (3M, St Paul, MN) has been found helpful in treating various conditions and injuries of the extremities, including lymphedema, edema in burned hands, and sprains or strains. However, the availability and easy application of the wrap have resulted in its common usage with or without adequate instructions. We report two cases in which severe pain and ischemia developed after this bandage was circumferentially applied to a finger to stop bleeding from a simple laceration. One patient required amputation at the level of the proximal interphalangeal joint; the other had resolution of venous congestion symptoms …

Custom-Made Angled Polyethylene Insert Exchange For Treatment Of Valgus Malalignment In Revision Total Knee Arthroplasty: A Case Report, Reilly J. Kuehn, Ch Christopher R Hanosh

UNM Orthopaedic Research Journal

Single- and dual-component revisions have typically been used to correct coronal malalignment after total knee arthroplasty (TKA). However, realignment of well-fixed components can result in complications such as bone loss and the need for increasing constraint of implants. Exchange to a custom-made angled polyethylene insert, although primarily implemented in cases of osteolysis, has been described with low complication rates and minimal loss of motion. We describe a 74-year-old woman who underwent TKA in January 2006 and presented to our clinic in March 2013 with symptoms of pain and instability of the right knee. We performed a revision TKA using two …

Workup And Treatment Of Acute Peripheral Nerve Injuries: A Review, Scott D. Evans

UNM Orthopaedic Research Journal

Peripheral nerve injury (PNI) can be a devastating and life-changing condition, normally caused from traumatic and iatrogenic events. Proper treatment of PNI remains difficult, with less than half of surgical procedures resulting in good or excellent outcomes. Subsequently, physicians should be aware of important principles that can help with management of acute PNI. I reviewed studies on PNI involving anatomy and classification schemes; workup such as electrodiagnostic tests, imaging procedures, and surgical indications; and operative treatment options (including nerve repair and use of nerve grafts and conduits, and nerve, muscle, and tendon transfers). Although treatment of these injuries continues to …
