Open Fractures: A Review, Alex Telis

UNM Orthopaedic Research Journal

Open fractures occur most commonly in men aged more than 50 years, which may result in lifetime costs for patients and healthcare systems. In the past 5 years, high-quality evidence for direct treatment of these fractures has increased. The expedient administration of intravenous antibiotics continues to be one of the most predictive factors of infection prevention. Open fractures are complicated injuries to classify owing to multiple factors that will be reviewed in the current study: severity of fracture and soft-tissue injury, thoroughness of debridement, time to initial treatment, modality of antibiotic delivery, and timing of definitive fracture fixation and soft-tissue …

Correlating Patient-Specific Anthropometric Variables With Soft-Tissue Thickness At The Superolateral Arthrocentesis Entry Site To The Knee, Savannah P. Krebsbach, Tony G. Pedri, Paul J. Johnson, Christina G. Kurnik, Gehron P. Treme

UNM Orthopaedic Research Journal

Background: Irrigation for treating septic joints in adults in the emergency department is possible but requires the development of novel systems that fit all body habitus. However, varying body habitus and age of patients may affect the amount of soft tissue surrounding the knee joint capsule. We examined whether the dimensions of the soft-tissue thickness at the superolateral approach of entry to the arthrocentesis site correlated with patient anthropometric data such as age, sex, height, weight, and body mass index (BMI, kg/m2).

Methods: Using the diagnosis code 844.2 (International Classification of Diseases, Ninth Revision), we reviewed findings of magnetic resonance …

Patterns In Bone Drilling Performance Before And After The 2017 Motors Skills Course Of The Southwest Orthopaedic Trauma Association, Naghmeh Zamani, Bill Lou, Ashkan Pourkand, Christina Salas, Deana Mercer, David I. Grow

UNM Orthopaedic Research Journal

Background: Although experience within the operating room can help surgeons learn simple bone-drilling techniques, outside training may be better suited for complex procedures. We adapted a rotary handpiece to evaluate bone drilling skills of orthopaedic resident physicians during the 2017 motor skills course of the Southwest Orthopaedic Trauma Association (SWOTA).

Methods: A total of 25 postgraduate year-one orthopaedic residents from seven institutions were asked to perform a bicortical drilling task three times before and after attending a motor skills course. Kinetic and kinematic data were collected using force, acceleration, and visual sensors.

Results: A total of 16 parameters were measured. …

Pelvic Ring Emergency Stabilization System (Press), Christina Salas, Thomas R. Howdieshell, Rachel Tufaro, Lauren Long, Ava K. Mauser, Aneesha Kondapi, Sherif H. Aboubakr

UNM Orthopaedic Research Journal

Pelvic ring fractures can be lethal owing to the potential for hemodynamic instability or arterial hemorrhage when the pelvic volume is increased. Pelvic binders are the standard of care used to provide circumferential compression to the pelvis, reducing the volume and increasing the intra-pelvic pressure. While commercially available options have been shown to provide adequate stability to the unstable pelvis, the circumferential nature of the binders limits access to the abdomen and groin regions, where accessibility is often necessary during the course of emergency treatment. We introduce a new technology known as the Pelvic Ring Emergency Stabilization System (PRESS). The …

Comparison Of Techniques Used For Application Of Hip Spica Cast To Treat Femoral Shaft Fractures In Children: Long-Term Follow-Up, Selina R. Silva, Elizabeth A. Szalay, Charlotte E. Orr, Brielle Payne Plost, Geneva Tranchida

UNM Orthopaedic Research Journal

After treatment using hip spica casts, femoral shaft fractures in children can appear well reduced in the operating room. However, the resulting bone length may quickly angulate or shorten. We describe a technique that places a well-molded hip spica cast to help decrease the risk of revision procedures and malunited fractures. We compared results of patients aged 1 to 6 years treated by one pediatric orthopaedic surgeon using the casting technique described (Group A, n = 25) to those treated by other orthopaedic surgeons who did not use the technique (Group B, n = 46). Although not statistically significant, results …

Subperiosteal Abscess Of The Distal Radius In A 13-Year-Old Boy: A Case Report, Anastasiya K. Haponyuk, Deana M. Mercer

UNM Orthopaedic Research Journal

Children and adolescents have the tendency to develop osteomyelitis in metaphyseal sinusoids because turbulent blood flow increases the probability of bacterial growth. Osteomyelitis in children is frequently misdiagnosed owing to lack of symptoms and specific findings from laboratory tests. Without rapid antibiotic treatment of osteomyelitis, complications such as subperiosteal abscesses may occur. We describe a 13-year-old boy who underwent irrigation and debridement to treat a subperiosteal abscess of the right distal radius and ulna, caused by acute osteomyelitis. After debridement, the patient was placed on a continuous 6-week course of nafcillin infusion through a peripherally inserted central catheter (PICC). The …

Rhabdomyolysis Of The Abdominal Wall In A 23-Year-Old Football Player: A Case Report, Brandon J. Hockenberry, Christopher A. Mcgrew, Shane P. Cass, James P. Toldi

UNM Orthopaedic Research Journal

Rhabdomyolysis is a syndrome caused by injury to skeletal muscle, which results in leakage of large quantities of potentially toxic intracellular contents into plasma. Causes include direct trauma, drug use, genetic muscle diseases, hyperthermia, seizures, ischemia, and severe exertion. We describe a rare case of exercise related rhabdomyolysis of the abdominal wall in a 23-year-old football player. He presented with painless hematuria after starting a new abdominal workout routine to lose weight. Although the workout was not excessively strenuous, it involved new exercises targeting a poorly trained muscle group. Results of initial workup indicated severely elevated levels of creatine kinase. …

Suspected Propofol-Related Infusion Syndrome After Lumbar Spinal Fusion With Total Intravenous Anesthesia: A Case Report, Tony G. Pedri, Matthew G. Wharton, Andrew J. Paterson

UNM Orthopaedic Research Journal

Propofol-related infusion syndrome (PRIS) is a welldocumented yet rare complication of prolonged infusions of propofol. It is characterized by a myriad of metabolic abnormalities, including cardiac arrhythmias, rhabdomyolysis, acute kidney injury, metabolic acidosis, and other disturbances. First described in children receiving extended propofol infusions to maintain sedation while in the intensive care unit, PRIS has now been described in every age group. It typically results in death. Management of this potentially devastating complication involves supportive treatment of the metabolic problems encountered and discontinuing the use of propofol. We describe a patient with suspected PRIS who underwent a two-stage lumbar spine …

Cutaneous Manifestations In The Fingertips After A Supracondylar Humerus Fracture In A 6-Year-Old Girl: A Case Report, Dan M. Quan, Kristin M. Loker, Lauren Mercer, David M. Bennett, Deana M. Mercer

UNM Orthopaedic Research Journal

A 6-year-old girl jumped from a swing and fell on her left arm, presenting to our clinic with a supracondylar fracture of the distal humerus. The child underwent closed reduction and percutaneous pinning. At 3-week follow-up, anterior interosseous nerve palsy was noted with concurrent manifestations in the median nerve distribution. Our patient was treated nonoperatively; at 8-week follow-up spontaneous resolution of cutaneous and motor symptoms was observed. Healthcare professionals should be aware that cutaneous lesions may develop after injury to the median nerve of the proximal forearm, which can result from supracondylar humerus fractures.

Posttraumatic Radioulnar Synostosis In A 63-Year-Old Man With Isolated, Non-Displaced Ulna Shaft Fracture: A Case Report, Audrey A. Rich, Deaba M. Mercer

UNM Orthopaedic Research Journal

Radioulnar synostosis in adults is a rare pathological fusion of the two forearm bones. When seen in adults, it is an uncommon complication after a minimally displaced ulnar fracture. We describe a 63-year-old man who presented with radioulnar synostosis after closed treatment of a left ulna midshaft fracture sustained 7 months earlier. At 10 weeks after presentation, the patient underwent radioulnar synostosis excision with nonsteroidal adjuvant therapy. At 18 months postoperatively, no pain was noted, with complete degree of flexion. Healthcare professionals should consider treating radioulnar synostosis with an operative excision in adults as initial management when forearm pronosupination is …

Radiographic Features And Remodeling Of Proximal Radius Osteomyelitis In A 14-Month-Old Child With Long-Term Follow-Up: A Case Report, Christopher L. Shultz, Deana M. Mercer

UNM Orthopaedic Research Journal

Pediatric primary hematogenous osteomyelitis is uncommon. Studies have been mainly small case series with limited clinical and radiographic followup. We present a child with primary hematogenous osteomyelitis and osteolysis of the proximal radius. Inflammatory laboratory values were normal, and blood and elbow aspirate cultures were negative for osteomyelitis. Diagnosis was made by findings of magnetic resonance imaging. The patient was successfully treated with intravenous antibiotics. At 4-year follow-up, she had normal range of motion and near symmetric proximal radial morphological features radiographically. To our knowledge, this is the most long-term radiographic follow-up of a patient with spontaneous osteomyelitis. The reported …

Open Reduction And Internal Fixation For Treating Pertrochanteric Femoral Fracture Below A Hip-Resurfacing Implant In A 65-Year-Old Man: A Case Report, Alex Telis, Christopher R. Hanosh

UNM Orthopaedic Research Journal

Periprosthetic proximal and pertrochanteric femur fractures around a well fixed hip resurfacing implant present a challenge to orthopaedic surgeons, as they do not allow the most biomechanically favorable fixation constructs in patients with otherwise highdemand levels of physical activity. A 65-year-old man hit a tree while skiing. He presented to our emergency department with a right-sided pertrochanteric fracture of the proximal femur beneath an implant used in prior hip resurfacing. The patient underwent open reduction and internal fixation with intraoperative fluoroscopyassisted manipulation to ensure fixation of the hip resurfacing. At 6-week follow-up, a slight varus collapse at the fracture was …

Recurrent Trigger Finger In The Early Postoperative Period: A Case Report, Kavita T. Vakharia, Moheb S. Moneim

UNM Orthopaedic Research Journal

Postoperative complications of trigger finger, a type of tendon entrapment, are low, and there is little information regarding evaluation after a complication occurs. Recurrent trigger finger is a rare occurrence, but often requires additional procedures to relieve symptoms. Here we present a case of recurrent trigger finger in the immediate postoperative period after the patient developed a cyst distal to the A1 pulley and synovitis. The first procedure demonstrated a thickened and tight A1 pulley as well as synovitis around the tendon. The patient developed continued clicking and trigger symptoms distal to the A1 pulley at the level of the …

Delayed Below-Knee Amputation For Treating Open Pantalar Dislocation With Extruded Talus: A Case Report, Jory Wasserburger, Andrew W. Parsons, Jessica C. Mcmichael, Richard A. Miller

UNM Orthopaedic Research Journal

Pantalar dislocation occurs when the talus is dislocated from the ankle, subtalar, and talonavicular joints. An extruded talus is seen when the talus protrudes out of an open wound with little or no soft-tissue attachment. We describe a 62-year-old man who underwent debridement and irrigation for treatment of a pantalar dislocation with an extruded talus. About 1 year postoperatively, he underwent a below-knee amputation. This case highlights the difficulties and complications associated with this injury.

Orthopaedic-Based Treatment Of Laurin- Sandrow Syndrome In A 13-Month-Old Child: A Case Report, Marcella R. Woiczik, John C. Carey, David M. Bennett, Brielle Payne Plost

UNM Orthopaedic Research Journal

Laurin-Sandrow syndrome (LSS) is a rare condition with only a few published cases in studies. This syndrome, originally described by Laurin in 1964 and again by Sandrow in 1970, can involve digit duplication with mirror hand and foot deformity, ulnar and tibial dimelia, and abnormalities of the knee, ankle, and nasal passages. A 7-month-old male infant presented to our clinic with limited function of his hands and feet due to multiple abnormalities. Results of clinical and radiographic examinations were suggestive of LSS, confirmed by a geneticist. Amputations through the knees, reconstructive pollicization of the right hand, and surgical removal of …

Acute Gluteus Medius And Minimus Intramuscular Tear In A 59-Year-Old Half-Marathon Runner: A Case Report, Claire E. Zeorlin, Eric R. Reynolds, Dustin L. Richter, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Acute gluteus medius and minimus tears are an infrequent and possibly underdiagnosed cause of lateral hip pain. When reported, they most commonly occur at the distal tendinous attachment at the insertion on the greater trochanter or at the musculotendinous junction. It is rare for muscle belly or proximal muscle tears to occur. They are more prevalent in the setting of degenerative joint disease, but cases have also been described in previously healthy athletes without preexisting joint or muscle disease. We describe a 59-year-old man who developed considerable pain and swelling on the left side of the hip during a halfmarathon …

Arthroscopic Wrist Debridement And Radial Styloidectomy For Advanced Scapholunate Advanced Collapse Wrist: Long-Term Follow-Up, P. C. Noback, M. Seetharaman, J. R. Danoff, M. Birman, M. P. Rosenwasser

Journal Articles

© The Author(s) 2017. Background: Symptomatic stage 2 or 3 scapholunate advanced collapse (SLAC) wrist is aggressively treated with salvage procedures, such as proximal row carpectomy or partial wrist fusion with resultant pain relief but limited motion. We hypothesize that arthroscopic synovectomy, radial styloidectomy, and neurectomy will preserve wrist motion, relieve pain, and delay or avoid salvage procedures. Methods: We evaluated outcomes in 13 wrists through questionnaires and 11 of these through additional physical examination at a mean follow-up of 5.0 years. Eight wrists were stage 2 and 5 were stage 3. Data at final follow-up included mobility/strength measurements, subjective …

Faculty & Staff Scholarship

Objective. Given the high prevalence of anxiety in adults with arthritis and other rheumatic diseases (AORD) and the subsequent need for interventions to reduce anxiety, this brief report sought to determine if evidential value exists to support the role of exercise for reducing anxiety in adults with AORD. Methods. Utilizing data from a prior meta-analysis, a recently developed approach, P- curve, was used to determine evidential value by assessing for publication bias and p-hacking. Binomial tests as well as the more robust Stouffer’s test were used to examine for evidential value. To examine the influence of selected studies on p-curve …

Osseointegrated Transcutaneous Device For Amputees: A Pilot Large Animal Model, Brian T. Grisez, Andrew E. Hanselman, Karim W. Boukhemis, Trapper A.J. Lalli, Brock A. Lindsey

Faculty & Staff Scholarship

Traditional above-the-knee amputation prosthetics utilize a stump-socket interface that is well-known for skin/socket problems, sitting difficulty, disuse osteopenia, and increased work of ambulation. As a result, we evaluated a novel osseointegrated transcutaneous implant in a large animal. The implant was designed to promote osseointegration at the bone-implant interface and minimize complications. As proof of concept, four Dorset sheep underwent a two-stage surgery for forelimb placement of an osseointegrated transcutaneous implant utilizing Compress�� technology (Biomet, Inc., Warsaw, IN). Two sheep received a long anchor plug (90 mm long x 9 mm in diameter) and two received a short anchor plug (46 …

Arthroscopic Knotless Rotator Cuff Repair: Factors Associated With Construct Selection And Recent Trends From A Manual Review Of 1617 Cases, S. S. Shah, A. Shah, V. Chadayammuri, M. Mcgill, N. Wei, D. V. Tuckman, N. A. Sgaglione

Journal Articles

© 2018 Prof. PK Surendran Memorial Education Foundation Purpose: Our aim was to identify predictors of construct selection and recent trends for arthroscopic knotless rotator cuff repair (RCR). Methods: A manual review of 1617 operative reports was performed. Results: A medium-sized tear had a threefold increase in odds of single row (SR) knotless repair (OR, 6.91; p = 0.009) versus SR knotted (OR, 3.05; p = 0.003). Generalist orthopaedic surgeons were 79% less likely to perform SR knotless repairs versus sports medicine trained specialists (p < 0.001). Conclusion: There was a significant increase from 2009 to 2016 in SR knotless and double row medial row knotless constructs contrasting the declining use of the SR knotted technique.

Can Weakness In End-Range Plantar Flexion After Achilles Tendon Repair Be Prevented?, K. F. Orishimo, S. Schwartz-Balle, T. F. Tyler, M. P. Mchugh, B. B. Bedford, S. J. Lee, S. J. Nicholas

Journal Articles

Background: Disproportionate end-range plantar flexion weakness, decreased passive stiffness, and inability to perform a heel rise on a decline after Achilles tendon repair are thought to reflect increased tendon compliance or tendon lengthening. Since this was first noted, we have performed stronger repairs and avoided stretching into dorsiflexion for the first 12 weeks after surgery.

Hypothesis: Using stronger repairs and avoiding stretching into dorsiflexion would eliminate end-range plantar flexion weakness and normalize passive stiffness.

Study Design: Case series; Level of evidence, 4.

Methods: Achilles repairs with epitendinous augmentation were performed on 18 patients. Plantar flexion torque, dorsiflexion range of motion …

Metabolic And Transcriptional Modules Independently Diversify Plasma Cell Lifespan And Function, Wing Y. Lam, Arijita Jash, Cong-Hui Yao, Lucas D'Souza, Rachel Wong, Ryan M. Nunley, Gordon P. Meares, Gary J. Patti, Deepta Bhattacharya

Faculty & Staff Scholarship

Plasma cell survival and the consequent duration of immunity vary widely with infection or vaccination. Using fluorescent glucose analog uptake, we defined multiple developmentally independent mouse plasma cell populations with varying life- spans. Long-lived plasma cells imported more fluo- rescent glucose analog, expressed higher surface levels of the amino acid transporter CD98, and had more autophagosome mass than did short-lived cells. Low amino acid concentrations triggered re- ductions in both antibody secretion and mitochon- drial respiration, especially by short-lived plasma cells. To explain these observations, we found that glutamine was used for both mitochondrial respira- tion and anaplerotic reactions, yielding …

Tranexamic Acid Increases Early Perioperative Functional Outcomes After Total Knee Arthroplasty., M. J. Grosso, D. P. Trofa, J. R. Danoff, T. R. Hickernell, T. Murtaugh, A. Lakra, J. A. Geller

Journal Articles

Background: The purpose of this study was to investigate the influence of tranexamic acid (TXA) on functional outcomes in the immediate postoperative period after total knee arthroplasty (TKA). We hypothesized that the known benefits of TXA would confer measurable clinical improvements in physical therapy (PT) performance, decrease pain, and decrease hospital length of stay (LOS).

Methods: We retrospectively analyzed 560 TKA patients, including 280 consecutive patients whose surgery was performed before the initiation of a standardized TXA protocol and the first 280 patients who received TXA after protocol initiation. Outcome measurements included postoperative changes in hemoglobin and hematocrit, LOS, pain …

Revision Total Shoulder Arthroplasty Is Associated With Increased Thirty-Day Postoperative Complications And Wound Infections Relative To Primary Total Shoulder Arthroplasty, V. Boddapati, M. C. Fu, W. W. Schairer, L. V. Gulotta, D. M. Dines, J. S. Dines

Journal Articles

© 2017, Hospital for Special Surgery. Background: With an increasing volume of primary total shoulder arthroplasties (TSA), the number of revision TSA cases is expected to increase as well. However, the postoperative medical morbidity of revision TSA has not been clearly described. Questions/Purposes: The purpose of this study was to determine the rate of postoperative complications following revision TSA, relative to primary TSA. In addition, we sought to identify independent predictors of complications, as well as to compare operative time and postoperative length of stay between primary and revision TSA. Methods: Patients who underwent primary/revision TSA between 2005 and 2015 …
