Carpometacarpal (CMC) arthritis of the thumb is one of the most common pathologies encountered in clinical hand and orthopedic surgery practices. Anatomy of the CMC joint and its biomechanics are theorized to predispose the articulation to laxity and subsequent degenerative changes. Diagnosis of CMC arthritis is primarily based on history, physical examination, and imaging findings, all of which coalesce to guide treatment. There are a multitude of treatment options for CMC arthritis, each with its own set of pearls and pitfalls with treatment decision making shared by surgeon and patient. Continued research and longitudinal data on outcome measures will assist in determining the ultimate "rule of thumb" for the treatment of CMC arthritis.

The consequences of malnutrition in spine surgery have been studied to a lesser degree compared to other orthopedic subspecialties. However, there is growing interest in understanding the effects of preoperative malnutrition on spine surgery outcomes. Literature on the relationship between malnutrition and spine surgery outcomes appeared sporadically in the late 1990s and early 2000s. Over the last decade, however, there has been a push to understand the sequelae of malnutrition on patients undergoing spine surgery. The aims of this review are to highlight: 1. the different parameters by which malnutrition has been defined and measured in spine surgery; 2. the prevalence of malnutrition in spine surgery; 3. the outcomes of spine surgery in malnourished patients; and 4. the effects of nutritional supplementation or interventions on spine surgery outcomes. Malnutrition has often been defined utilizing specific serological laboratory values or nutritional indices. Serologic values of malnutrition include an albumin < 3.5 g/dL, transferrin < 150 mg/ dL, or a total lymphocyte count of < 1,500 cells/mm3 . The available literature reports that the prevalence of malnutrition in patients undergoing lumbar spine surgery ranges from 5% to 50%, with most literature supporting a value toward the higher end of this spectrum. Malnourished patients undergoing spine surgery have higher rates of surgical site infections, medical complications, lengths of stay, ICU admissions, 30-day and 1-year mortalities, reoperations, 30-day readmissions, and costs of care. Given the plethora of spine surgeries performed in the country annually and the prevalence of malnutrition in up to 50% of our patients, we recommend performing preoperative nutritional assessments on all patients to ensure their optimization prior to surgery.

Orthopedic surgeons frequently use fluoroscopy and flat plate X-ray in the operating room. As the length of surgeons' careers gets longer, the risk of potential for harm from radiation exposure also grows. Knowledge of the background and science of radiation, the C-arm, and various ways that surgeons can protect themselves is fundamental and should be incorporated into residency education for orthopedic surgery. This review provides information that we hope will better prepare residents in orthopedic surgery to use fluoroscopy and X-rays and protect themselves from radiation risks.

The treatment of massive irreparable rotator cuff tears has been a controversial topic with multiple procedures described. Research trends have been growing rapidly over the past decade resulting in a greater understanding of its natural evolution. No singular superior procedure has been described. Rather, treatment options should be weighed in the setting of patient expectations, comorbidities, and the findings from clinical examinations. Based on the current literature, practitioners should be aware of the available treatment options and the most appropriate settings for employing each option. This review discusses the history of massive irreparable rotator cuff tears and evaluates each treatment option based on the highest quality of research available.

Anterior cruciate ligament (ACL) repair is a procedure that has been used to treat torn ACLs dating back to the early 1900s. With unpredictable outcomes of repair, a paradigm shift led to surgeons to opt for ACL reconstruction as a new gold standard, as the evidence showed a more reliable outcome. However, there has been a recent resurgence in ACL repair worthy of review, particularly in proximal avulsions. Suture anchor repair is one repair technique in which recent studies show low failure rates, low reoperation rates, and favorable clinical outcomes. More recent data supports augmenting this strategy with suture tape. An innovation in ACL repair techniques is the Bridge-Enhanced ACL Repair (BEAR) technique, which combines a patient's whole blood with a collagen-based scaffold to augment the repair. While promising results have been shown with these techniques, narrow indications are necessary for a successful ACL repair.

The human body has evolved greatly over time and the hand has shown some of the most intricate changes. Most evolutionary experts attribute this to the greater use of tools facilitated by the early hominid's transition to a bipedal gait. Increased tool use drove these changes by providing a convincing reproductive advantage for early humans. In particular, hand adaptations resulted from two types of grips that were fundamental in our development: the precision grip and the power grip. To fully understand how these changes in development occurred, a review of evolutionary theory will be proffered and further discussion of the unique architecture of the hands of our closest living relatives compared with that of humans will follow. Finally, we will examine the two uniquely human grips, the anatomic adaptations that allowed for their development, and the reasoning behind how these grips provided a compelling reproductive advantage.

Background: Handwritten consent forms for medical treatment are commonly used despite the associated risk of documentation errors. We performed an internal audit of handwritten surgical consent forms to assess the quality of consenting practices within the department of hand surgery at our orthopedic specialty hospital.

Methods: A sample of 1,800 charts was selected. Con- sents were assessed for procedure type, physician details, abbreviations, consistency, and legibility.

Results: A total of 1,309 charts met the inclusion crite- ria. Two hundred and eight consents contained at least one illegible word. The name of the consenting physician was not listed or illegible on 114 forms. Medical abbreviations were found on 1.8% of all included forms, and 19 consent forms contained a crossed-out word or correction.

Conclusions: Although the majority of the handwrit- ten consent forms were complete, accurate, and legible, there were notable errors in the consenting process at our institution. Documentation errors have medical and ethical ramifications. Further research into consenting practices is necessary to improve the quality of consent forms and the process of informed consent.

Orthopedic surgeons may encounter patients with musculo- skeletal complaints that are not localized to a specific joint or anatomical area. The list of diagnoses that may cause generalized pain originating from bones, muscles, fasciae, and joints, including surrounding tissues like tendons, ligaments, and bursae, is vast; starting with influenza or fibromyalgia and ending with mycetism and ultra-rare he- reditary disorders. A systematic multidisciplinary approach is required. Many of these patients require referral to rheu- matology, endocrinology, or other specialties but at least a basic understanding of differential diagnosis is needed. The purpose of this review is to comprehensively examine the clinical presentation of various causes of generalized musculoskeletal pain and create a mental framework to aid the diagnostician in achieving the correct diagnosis in an orderly and efficient manner.

Sex-based differences in outcomes of tibial tubercle anteromedi- alization. Bull Hosp Jt Dis. 2022;80(4):252-6. Abstract Background: Previous research has demonstrated sex- based differences in patient-reported outcomes of orthopedic surgical procedures. The hypothesis of the current study was that females would have inferior patient-reported outcomes to their male peers following a tibial tubercle anteromedial- ization (AMZ) procedure for both patellofemoral instability and cartilage defects.

Methods: Patients who had undergone AMZ for isolated osteochondral defect or patellofemoral instability with a minimum follow-up time of 1 year were identified. They were then asked to complete several patient-reported outcome questionnaires that were then statistically analyzed.

Results: Overall, 109 patients were included in this study. Seventy-nine patients (72.5%) were female with a mean follow-up duration of 3.4 ± 2.0 years. Forty-seven females had AMZ for patellar instability while 32 females had AMZ for osteochondral defects. There were no statistically signifi- cant differences between sexes with respect to concomitant procedures performed, visual analog scale (VAS) pain score, or patient reported outcome (PRO) scores at follow-up (p > 0.05). There was no statistically significant difference with respect to outcomes between the sexes for AMZ overall and when isolating the sexes based on indication.

Conclusion: This study demonstrates that female patients undergoing AMZ have short-term clinical and functional outcomes that are not significantly different to those reported in males.

Rupture of the triceps tendon is a rare event, and the care could be often problematic for orthopedic surgeons. Cases of triceps tendon re-rupture are even rarer. The stump is often retracted, atrophic, and the tissue quality is poor. Several surgical techniques have been reported. We present our surgi- cal reconstruction using free semitendinosus (ST) autograft.
