Self-induced Hot Water Finger Burn Trying to Get Feeling Back after Ropivacaine Block.

This case report is about a patient with self-induced hot water burns several hours after an infraclavicular block with ropivacaine for a scaphoid fracture operation. This patient was honest about what happened. However, some patients are too embarrassed to admit what they did to themselves. The injury may be misdiagnosed by the emergency department physician or by the surgeon because the history is incomplete. The resulting burn, which can lead to fingertip loss when severe, can be erroneously misdiagnosed as an ischemic injury after lidocaine with epinephrine local anesthesia. Most hand surgeons have seen ischemic finger injuries the morning after failed finger replantation. Acutely ischemic fingers from arterial insufficiency do not have parallel hot water burn lines, reactive hyperemia at the base of the burn, or burn blisters at the fingertips. The purpose of this article and its video is to help physicians and nurses recognize the three signs of self-induced hot water finger burns after local anesthesia: (1) a parallel hot water line in the fingers at the proximal burn level; (2) reactive hyperemia just proximal to the burn line; (3) burn blisters in the submerged fingertips. When seeing postoperative patients with these signs, the examining clinician may tactfully ask: "Did you try to get the feeling back in your fingers by warming them?" It is hoped that the patient may then reveal that he tried warming the finger in water, and that may lead to the truth that the water was indeed too hot.

Surgical Management of Triquetral Osteoid Osteoma with Adjunct Tetracycline for Intraoperative Visualization: A Case Report.

CASE: We report the case of a 15-year-old male patient presenting with persistent wrist pain after surgical treatment of a triquetral osteoid osteoma. The patient was found to have a persistent nidus. These tumors are difficult to observe intraoperatively or through fluoroscopy, limiting adequate resection and resulting in continued pain. CONCLUSION: The nidus was excised successfully through an unusual technique using tetracycline for intraoperative identification. The patient remains asymptomatic without recurrence at 31 months postoperative. Difficulties visualizing and removing carpal lesions leading to recurrence are described.

Factors Driving Patient Perception of Quality Care After Primary Total Hip and Total Knee Arthroplasty.

INTRODUCTION: Differences in female and male patient perception of care and satisfaction following primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) were assessed via Hospital Consumer Assessment of Healthcare Providers and Systems survey, demographic, and clinical data. METHODS: After institutional review board approval, a retrospective review of the Hospital Consumer Assessment of Healthcare Providers and Systems survey responses at a private, academic, level-I trauma center was performed from January 2011 to December 2013. Inclusion criteria were primary THA and TKA patients who were 18 years or older and returned the survey. RESULTS: Overall, 1,166 THA and 1,411 TKA were included, with 55.0% of female THA patients and 64.5% of male THA patients highly satisfied (P = 0.002). The mean overall hospital rating was 7.2 for female THA and 7.8 for male THA (P = 0.003) patients. No significant differences was found in the TKA cohort. For all cohorts, the Nurse Communication with Nurses domain reported the greatest correlation with overall hospital rating (range, ρ = 0.418 to ρ = 0.502; P < 0.0001). DISCUSSION: This series indicated that initiatives to improve patient care and patient perception of care should focus on nurse-patient communication, hospital staff responsiveness, the care transition process, and hospital environment. Patient sex was a significant factor in the overall satisfaction for THA, with female patients reporting significantly lower ratings than male patients.

Where Are the Women in Orthopaedic Surgery?

BACKGROUND: Although women account for approximately half of the medical students in the United States, they represent only 13% of orthopaedic surgery residents and 4% of members of the American Academy of Orthopaedic Surgeons (AAOS). Furthermore, a smaller relative percentage of women pursue careers in orthopaedic surgery than in any other subspecialty. Formal investigations regarding the gender discrepancy in choice of orthopaedic surgery are lacking. QUESTIONS/PURPOSES: (1) What reasons do women orthopaedic surgeons cite for why they chose this specialty? (2) What perceptions do women orthopaedic surgeons think might deter other women from pursuing this field? (3) What role does early exposure to orthopaedics and mentorship play in this choice? (4) What professional and personal choices do women in orthopaedics make, and how might this inform students who are choosing a career path? METHODS: A 21-question survey was emailed to all active, candidate, and resident members of the Ruth Jackson Orthopaedic Society (RJOS, n = 556). RJOS is the oldest surgical women's organization incorporated in the United States. An independent orthopaedic specialty society, RJOS supports leadership training, mentorship, grant opportunities, and advocacy for its members and promotes sex-related musculoskeletal research. Although not all women in orthopaedic practice or training belong to RJOS, it is estimated that 42% of women AAOS fellows are RJOS members. Questions were formulated to determine demographics, practice patterns, and lifestyle choices of women who chose orthopaedic surgery as a specialty. Specifically, we evaluated the respondents' decisions about their careers and their opinions of why more women do not choose this field. For the purpose of this analysis, the influences and dissuaders were divided into three major categories: personal attributes, experience/exposure, and work/life considerations. RESULTS: The most common reasons cited for having chosen orthopaedic surgery were enjoyment of manual tasks (165 of 232 [71%]), professional satisfaction (125 of 232 [54%]), and intellectual stimulation (123 of 232 [53%]). The most common reasons indicated for why women might not choose orthopaedics included perceived inability to have a good work/life balance (182 of 232 [78%]), perception that too much physical strength is required (171 of 232 [74%]), and lack of strong mentorship in medical school or earlier (161 of 232 [69%]). Respondents frequently (29 of 45 [64%]) commented that their role models, mentors, and early exposure to musculoskeletal medicine were influential, but far fewer (62 of 231 [27%]) acknowledged these in their top five influences than they did the more "internal" motivators. CONCLUSIONS: To our knowledge, this is the largest study of women orthopaedic surgeons regarding factors influencing their professional and personal choices. Our data suggest that the relatively few women currently practicing orthopaedics were attracted to the field because of their individual personal affinity for its nature despite the lack of role models and exposure. The latter factors may impact the continued paucity of women pursuing this field. Programs designed to improve mentorship and increase early exposure to orthopaedics and orthopaedic surgeons may increase personal interest in the field and will be important to attract a diverse group of trainees to our specialty in the future.

Treatment of phalangeal fractures.

Treatment of phalangeal fractures depends on the characteristics of the fracture, condition of the soft tissue envelope, associated injuries, patient functional requirements, and surgeon familiarity and comfort with various techniques. Most phalangeal fractures can be treated successfully with nonoperative means. Surgery is considered to treat unstable injuries, articular incongruity, concomitant soft tissue damage, or other situations in which restoration of anatomy and preservation of function are achieved only via operative stabilization. Careful soft tissue handling and early mobilization are premises on which surgical phalangeal fracture treatment is based.

Clinical outcomes for patients with soft tissue sarcoma of the hand.

BACKGROUND: In an earlier report from the current study center regarding surgical treatment for patients with soft tissue sarcoma (STS) of the hand, it was concluded that repeat resection or amputation improves outcomes. Since then, the authors have aggressively sought to achieve negative resection margins, using standard or modified amputations when needed, and performing repeat resections to negative surgical margins when they were not achieved at the time of initial surgery. The current review was conducted to determine whether this approach resulted in better outcomes. METHODS: A retrospective review of 53 patients with STS of the hand who were treated between 1996 and 2005 was performed. Recurrence-free survival (RFS) and functional outcome of hand-preserving procedures were assessed according to the Musculoskeletal Tumor Society (MSTS) system. RESULTS: The median RFS was not reached at the time of last follow-up. Of 53 patients, 6 (11%) had positive microscopic resection margins. Three patients underwent repeat resection to negative surgical margins, whereas another 3 patients did not. All 3 patients with positive microscopic surgical margins that were not re-excised developed local disease recurrence; 2 patients also developed distant metastases. Two of the 50 patients with negative resection margins developed distant metastases. All 5 patients who developed local and/or distant disease recurrence had deep tumors. The median MSTS score was 29 (interquartile range, 27-30). Patients who underwent more extensive resections, such as double ray amputations, had lower MSTS scores. CONCLUSIONS: Suboptimal biopsies and positive resection margins are associated with local and distant disease recurrence in patients with STS. The results of the current study suggest that aggressive surgical treatment can result in better clinical outcomes, and underscore that care must be taken when planning biopsies of hand tumors.

Complications of radiation therapy to the hand after soft tissue sarcoma surgery.

PURPOSE: Radiation has been shown to improve local control after resection of soft tissue sarcomas. However, it may also result in major complications in the hand, given the compact nature of functional tissues and limited tissue volumes in the hand. The purpose of this investigation was to describe the hand-specific complications of radiation therapy for patients with soft tissue sarcoma of the hand (STSH). METHODS: We performed a retrospective chart review of 55 consecutive patients with STSH treated by a single surgeon between 1993 and 2006. We identified 26 patients who were treated with external beam radiation, brachytherapy, or both, either preoperatively or postoperatively, and reviewed their clinical course. RESULTS: After a median follow-up of 7 years, 29 treatment-related complications occurred in 19 patients who had received radiation, whereas 3 of the 29 patients treated with surgery alone developed complications. All patients who received brachytherapy and 14 of the 21 treated with external beam radiation alone developed complications. There were 5 early minor, 2 early major, 3 late minor, and 19 late major complications. CONCLUSIONS: Patients with STSH who underwent radiation therapy had a high rate of complications. The complication rate in our series was higher in patients who had brachytherapy catheters placed adjacent to finger joints. A better understanding of predictors of complications will help to determine the optimal timing and type of radiation therapy to treat patients with STSH. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

The advantage of throwing the first stone: how understanding the evolutionary demands of Homo sapiens is helping us understand carpal motion.

Unlike any other diarthrodial joint in the human body, the "wrist joint" is composed of numerous articulations between eight carpal bones, the distal radius, the distal ulna, and five metacarpal bones. The carpal bones articulate with each other as well as with the distal radius, distal ulna, and the metacarpal bases. Multiple theories explaining intercarpal motion have been proposed; however, controversy exists concerning the degree and direction of motion of the individual carpal bones within the two carpal rows during different planes of motion. Recent investigations have suggested that traditional explanations of carpal bone motion may not entirely account for carpal motion in all planes. Better understanding of the complexities of carpal motion through the use of advanced imaging techniques and simultaneous appreciation of human anatomic and functional evolution have led to the hypothesis that the "dart thrower's motion" of the wrist is uniquely human. Carpal kinematic research and current developments in both orthopaedic surgery and anthropology underscore the importance of the dart thrower's motion in human functional activities and the clinical implications of these concepts for orthopaedic surgery and rehabilitation.

Acute fractures of the scaphoid.

Fractures of the scaphoid must be treated promptly to minimize the risk of malunion and nonunion. Although most scaphoid fractures have been reported to heal well with cast immobilization, advances in surgical techniques have greatly changed the decision-making process for treatment. It is worthwhile to review the different management options for acute fractures.

Nerve transfers for adult traumatic brachial plexus palsy (brachial plexus nerve transfer).

Adult traumatic brachial plexus injuries can have devastating effects on upper extremity function. Although neurolysis, nerve repair, and nerve grafting have been used to treat injuries to the plexus, nerve transfer makes use of an undamaged nerve to supply motor input over a relatively short distance to reinnervate a denervated muscle. A review of several recent innovations in nerve transfer surgery for brachial plexus injuries is illustrated with surgical cases performed at this institution.

The effect of local corticosteroid or ketorolac exposure on histologic and biomechanical properties of rabbit tendon and cartilage.

Tendonitis, tenosynovitis, and the arthritides are clinical problems commonly encountered in daily orthopaedic practice. Systemic anti-inflammatories, physical therapy, and local corticosteroid injections all are used as nonoperative treatments of these conditions. Systemic anti-inflammatory agents and local corticosteroid agents, however, can be associated with adverse effects that render them intolerable to some patients. As a preliminary study assessing the feasibility of local injection of nonsteroidal anti-inflammatory medication, the histological and biomechanical effects of local exposure of rabbit cartilage and tendon to injectable steroidal (corticosteroid) and injectable nonsteroidal anti-inflammatory agents (ketorolac tromethamine, KT) were determined. Thirty rabbits underwent bilateral knee joint, patellar tendon, and Achilles tendon injections with either normal saline, corticosteroid, or KT. Mechanical and histologic evaluation of the tissues was performed at 6 and 15 weeks after injection. Gross tendon adhesions were observed in more corticosteroid-treated specimens than those exposed to normal saline or KT. Microscopic evaluation of tendons revealed no significant differences among the three groups. Mild cartilage degenerative changes were noted across all groups. Evidence of cartilage necrosis was noted for the corticosteroid-treated group only. Tendons exposed to corticosteroid or KT demonstrated increased load and energy to failure, but exhibited no difference in material stiffness or strain. The use of an injectable nonsteroidal anti-inflammatory agent may be safe and even pose less threat to local tissues after intra-articular and peri-tendinous administration.

Mini-pig fresh osteochondral allografts deteriorate after 1 week of cold storage.

As a well-defined animal transplantation model, the mini-pig potentially is well-suited for large animal studies of fresh osteochondral allograft transplantation. This study was done to determine the histologic characteristics and function of proteoglycan synthesis of mini-pig articular cartilage after refrigeration in basal media for as much as 6 weeks. Osteochondral sections of 10 mini-pig knees were refrigerated in various media at 4 degrees C for 1 to 42 days after slaughter. Four hundred twenty samples were evaluated by 35S uptake and 260 samples by histologic evaluations. Proteoglycan synthesis declined by 7 days to 21% of the level measured on Day 1 and was undetectable at 42 days. Histologic evaluation revealed progressive degeneration. Mankin scores rose from 3.69 +/- 0.27 on Day 1 to 6.40 +/- 0.18 on Day 7, and logarithmically increased to 10.83 +/- 0.07 on Day 42. These results indicate that the metabolic characteristics of porcine articular cartilage were not retained after refrigeration in basal media for 7 days. Optimum cold storage of porcine osteochondral allografts for cartilage transplantation research may be less than 7 days. Because osteochondral grafts for clinical use currently are stored for greater than 7 days, similar studies of the viability of human articular cartilage are needed.

Acute synovitis of the knee resulting from intra-articular knee penetration as a complication of flexible intramedullary nailing of pediatric femur fractures: report of two cases.

Management of pediatric femur fractures using flexible intramedullary nail fixation is widely accepted. Few complications have been reported in the literature; these include primarily malunions and nonunions. The authors present two cases of a previously unreported complication-acute synovitis of the knee following intra-articular penetration of the knee joint by migration of a flexible nail.
