RESUMO

BACKGROUND: When treated conservatively, unstable distal clavicle fractures demonstrate a high symptomatic nonunion rate. While a variety of surgical techniques have been described, many of these techniques are associated with high failure rates and hardware-related complications. The surgical technique used in this study has shown promising biomechanical results; however, long-term clinical results have not yet been described. PURPOSE: To assess the clinical and radiological outcomes of a surgical technique for fixing displaced distal clavicle fractures using a combination of cortical button fixation and coracoclavicular (CC) ligament reconstruction. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We conducted a retrospective review of 22 consecutive patients with displaced, unstable Neer type II or V distal clavicle fractures who underwent this surgical technique from 2012 to 2019. Primary outcome variables were radiographic union, patient satisfaction, and postoperative shoulder function. Preoperative and postoperative University of California, Los Angeles (UCLA), and American Shoulder and Elbow Surgeons (ASES) scores were compared. Secondary outcome variables included intraoperative complications, postoperative complications, time to radiographic union, and preoperative and postoperative CC distance. Quality of life was assessed using preoperative and postoperative 36-Item Short Form Health Survey (SF-36) scores. RESULTS: Nearly all (21/22) patients were available for a final review; 1 patient was lost to follow-up at 2 weeks. All 21 patients achieved radiographic union by 4 months (mean, 60.38 days; range, 41-84 days; 95% CI, 53.80-66.96 days). All patients were satisfied with the surgical procedure and their functional outcome. The mean UCLA score improved from 5.36 (95% CI, 4.14-6.60) preoperatively to 32.52 (95% CI, 30.56-34.48) postoperatively (mean difference, 27.14; P < .001). The mean ASES score improved from 16.23 (95% CI, 9.79-22.67) preoperatively to 88.11 (95% CI, 81.82-94.40) postoperatively (mean difference, 71.91; P < .001). Statistically significant improvements in SF-36 scores were seen in the physical functioning, role limitations due to physical health, pain, social functioning, and emotional well-being categories. There were 3 postoperative complications, including 1 patient with a minor complication secondary to hardware irritation, 1 patient with adhesive capsulitis, and 1 patient with wound dehiscence requiring wound closure. CONCLUSION: We describe a surgical technique for fixing displaced distal clavicle fractures using a combination of cortical button fixation and CC ligament reconstruction that resulted in a 100% union rate and excellent clinical outcomes with acceptable complications.

RESUMO

BACKGROUND: Unstable distal clavicular fractures treated surgically are associated with high failure rates and hardware-related complications. Newer techniques have shown promising early clinical results with fewer hardware complications; however, their biomechanical performance has not been assessed. This study biomechanically compared a distal-third locking plate with 3 newer techniques that incorporate coracoid fixation into the construct. METHODS: The study randomized 36 adult fresh frozen cadaveric shoulders to 4 groups: (1) distal-third locking plate (P); (2) distal-third locking plate with a coracoid button augmentation (P + CB); (3) coracoclavicular button (CB); and (4) coracoclavicular button with coracoclavicular ligament reconstruction using semitendinosus allograft (CB + CC). After fixation, each specimen was stressed in the coronal plane. Cyclic displacement, load at 10-mm displacement, and ultimate load to failure were measured. RESULTS: All 3 experimental groups biomechanically outperformed the locking plate. Mean load to failure was significantly higher in the CB (343 ± 76 N) and CB + CC (349 ± 94 N) groups compared with the P group (193 ± 52 N). There was also significantly less cyclic displacement in the CB (4.3 ± 1.9 mm) and CB + CC (4.4 ± 1.9 mm) groups compared with the P group (8.2 ± 2.9 mm). With respect to load at 10 mm of displacement, which essentially measures a clinical failure, the P + CB (235 ± 112 N), CB (253 ± 111 N), and CB+CC (238 ± 76 N) experimental groups significantly outperformed the P group (96 ± 29 N). CONCLUSIONS: CB and CB + CC techniques demonstrated more than 75% greater strength than the traditional locking plate alone. Coupled with greater overall construct strength and lower-profile hardware, these newer techniques may result in improved clinical outcome and fewer hardware-related complications.

RESUMO

Management of distal clavicle fractures remains controversial. Various treatment options have been described including open reduction and internal fixation with hook plate fixation, tension band wiring, screw fixation, and distal locking plates. Many of these techniques are associated with a high perioperative complication rate. We describe a surgical technique that allows indirect fixation of distal clavicle fractures and reconstruction of the CC ligaments without the use of prominent hardware.

RESUMO

OBJECTIVES: To determine whether ketorolac administered in the immediate perioperative period affects the rate of nonunion in femoral and tibial shaft fractures. DESIGN: Retrospective comparative study. SETTING: Single Institution, Academic Level 1 Trauma Center. PATIENTS: Three hundred and thirteen skeletally mature patients with 137 femoral shaft (OTA 32) and 191 tibial shaft (OTA 42) fractures treated with intramedullary rod fixation. INTERVENTION: Eighty patients with 33 femoral shaft and 52 tibial shaft fractures were administered ketorolac within the first 24 hours after surgery (group 1-study group). Two-hundred thirty-three patients with 104 femoral shaft and 139 tibial shaft fractures were not (group 2-control group). MAIN OUTCOME MEASUREMENTS: Rate of reoperation for repair of a nonunion and time to union. RESULTS: Average time to union of the femur was 147 days for group 1 and 159 days for group 2 (P = 0.57). Average time to union of the tibia was 175 days for group 1 and 175 days for group 2 (P = 0.57). There were 3 femoral nonunions (9%) in group 1 and eleven femoral nonunions (11.6%) in group 2 (P = 1.00). There were 3 tibial nonunions (5.8%) in group 1 and 17 tibial nonunions (12.2%) in group 2 (P = 0.29). The average dose of ketorolac for patients who healed their fracture was 85 mg, whereas it was 50 mg for those who did not (P = 0.27). All patients with a nonunion in the study group were current smokers. CONCLUSIONS: Ketorolac administered in the first 24 hours after fracture repair for acute pain management does not seem to have a negative impact on time to healing or incidence of nonunion for femoral or tibial shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVE: To evaluate the clinical and radiographic results associated with the use of a percutaneous suprapatellar (SP) portal and accompanying instrumentation for tibial intramedullary nail (IMN) insertion using a semiextended approach. DESIGN: Prospective, nonrandomized, nonconsecutive study. SETTING: Level 1 trauma center. PATIENTS AND METHODS: From June 2007 to January 2011, 56 fractures (55 patients) underwent intramedullary nailing of a tibia fracture with a semiextended approach through a SP portal. Radiographic and clinical follow-up examinations were performed at a minimum of 1 year after the index procedure. Measurements included bone healing, tibial alignment, knee range of motion, pain drawings, pain scoring (visual analogue scale), functional outcome (Lysholm and SF-36 scoring), evaluation of prenail and postnail insertion arthroscopic images of the patella-femoral (PF) joint (subgroup of study patients), and 1-year follow-up magnetic resonance imaging (MRI) scans (STIR and T2 gradient echo) of the knee to evaluate the PF joint cartilage. MRI scans were reviewed by an independent bone radiologist, whereas arthroscopic images were evaluated by an independent sports medicine fellowship-trained orthopaedic surgeon. RESULTS: Thirty-six patients (37 fractures) were available for follow-up at a minimum of 1 year (range: 12-49 months) after the index procedure. All but 2 fractures healed after the index procedure (94.6%). There was 1 radiographic malunion (2.7%). The mean Lysholm knee score was 82.14. Mean SF-36 physical and mental scores were 40.8 and 46.0, respectively. Mean arc of knee motion was 124.4 degrees for the affected extremity compared with 127.2 degrees for the contralateral knee. One patient (2.7%) complained of mild pain at the scar, but no patient complained of anterior knee pain either at the PF joint or at the anterior proximal tibia. In 13 of 15 patients undergoing an arthroscopic assessment of the PF joint, prenail and postnail insertion, no cartilage changes, or pressure points were seen either at the patella or at the trochlea groove. Two patients had grade II chondromalacia of the trochlea immediately after the procedure, but these did not correspond with either MRI scans or clinical findings at 1 year. When the remainder of the 1-year MRI scans were reviewed, 1 knee (2.7%) in a patient that did not have an arthroscopic examination was found to have grade II chondromalacia in the PF joint, but this did not correlate with the clinical examination, which was normal. CONCLUSIONS: This is the first paper to critically document clinical and radiographic results using the percutaneous SP portal with the semiextended approach for IMN of the tibia. Our 1 year results indicate that the procedure resulted in excellent tibial alignment, union, and knee range of motion, with rare sequelae in the PF joint based on immediate arthroscopy and 1-year MRI scans and clinical examinations. Even more interesting was the absence of anterior tibial pain often found when a tibial nail is inserted in a standard fashion.

RESUMO

OBJECTIVES: To determine if indomethacin has a positive clinical effect for the prophylaxis of heterotopic ossification (HO) after acetabular fracture surgery. To determine whether indomethacin affects the union rate of acetabular fractures. DESIGN: Prospective randomized double-blinded trial. SETTING: Level 1 regional trauma center. PATIENTS: Skeletally mature patients treated operatively for an acute acetabular fracture through a Kocher-Langenbeck approach. INTERVENTION: Patients were randomly allocated to 1 of 4 groups comparing placebo (group 1) to 3 days (group 2), 1 week (group 3), and 6 weeks (group 4) of indomethacin treatment. MAIN OUTCOME MEASUREMENTS: Factors analyzed included the overall incidence, Brooker class and volume of HO, radiographic union of the acetabular fracture, and pain. Patients were followed clinically and radiographically at 6 weeks, 3 months, 6 months, and 1 year. Serum levels of indomethacin were drawn at 1 month to assess compliance. Computed tomographic scans were performed at 6 months to assess healing and volume of HO. RESULTS: Ninety-eight patients were enrolled into this study, 68 completed the follow-up and had the 6-month computed tomographic scan, and there was a 63% compliance rate with the treatment regimen. Overall incidence of HO was 67% for group 1, 29% for group 2 (P = 0.04), 29% for group 3 (P = 0.019), and 67% for group 4. The volume of HO formation was 17,900 mm for group 1, 33,800 mm for group 2, 6300 mm for group 3 (P = 0.005), and 11,100 mm for group 4. The incidence of radiographic nonunion was 19% for group 1, 35% for group 2, 24% for group 3, and 62% for group 4 (P = 0.012). Seventy-seven percent of the nonunions involved the posterior wall segment. Pain visual analog scores (VASs) were significantly higher for patients with radiographic nonunion (VAS 4 vs. VAS 1, P = 0.002). CONCLUSIONS: Treatment with 6 weeks of indomethacin does not appear to have a therapeutic effect for decreasing HO formation after acetabular fracture surgery and appears to increase the incidence of nonunion. Treatment with 1 week of indomethacin may be beneficial for decreasing the volume of HO formation without increasing the incidence of nonunion. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

The history of limb-lengthening surgery can be traced back to the nineteenth century. Since that time, the orthopaedic community has made tremendous progress in performing successful lengthening procedures. Among the important contributors to the field, Dr. Gavril Ilizarov remains one of the most significant innovators. Because of advancements over the past century, limb lengthening has become a viable method of treating severe bony deformities and defects. This article, the first of a two-part series, reviews the history of distraction osteosynthesis.

RESUMO

Hospital readmissions are quality indicators of healthcare delivery. Our purpose is to examine the effect of a program designed to reduce readmissions after total joint replacement. We initiated a comprehensive program with 4 goals: (1) outpatient workup of venous thromboembolism; (2) decrease surgical site infection; (3) early follow-up with primary care physicians; and (4) increase physician awareness of the financial and quality-related ramifications of unplanned readmissions. We then compared readmission rates before our initiative was instituted (2005-2006) to 3 years after implementation (2007-2009). Readmission rates preintervention were 3.70 and 3.29 for total hip replacement (THR) and knee replacement (TKR), respectively. Postintervention rates fell to 1.78 and 1.98, respectively, representing a 47.2% reduction of readmission for THR and 39.8% for TKR (P<.05). These results demonstrate the success of our program in reducing readmissions. This may result in reductions in healthcare costs and improvement in quality of care.

RESUMO

Standard techniques for immobilization of a tibia shaft fracture in the emergency department in a long-leg splint can be cumbersome, technically difficult, and often requires the use of an assistant. We have developed a novel technique for the reduction and splinting of tibial shaft fractures, which uses a "hammock" constructed of stockinette, which allows a single consulting orthopaedic physician to rapidly reduce and place a long-leg plaster splint or cast on a patient. This technique was performed on 12 consecutive patients with a total of 12 tibial shaft fractures. Translation, angulation, and shortening of the fracture were documented in anteroposterior and lateral views of the injured tibia and these parameters were compared against values measured after the hammock technique was used to reduce and splint the fracture. Pre-"hammock" average values for fracture displacement in the anteroposterior plane for translation, angulation, and shortening were 10.5 mm (53.1%), 12.0°, and 9.4 mm, respectively. Post-"hammock" average values for fracture displacement in the anteroposterior plane for the same parameters were 8.7 mm (44.4%), 4.2°, and 7.9 mm, respectively. Pre-"hammock" average values for fracture displacement in the lateral plane for translation and angulation were 4.9 mm and 8.7°. Post-"hammock" average values for fracture displacement in the lateral plane for the same parameters were 4.9 mm and 2.0°, respectively. These results show that this technique is able to achieve the goals of fracture reduction and immobilization in a rapid fashion when help is not available.

RESUMO

Neurofibromatosis type 1 (NF-1) is an autosomal dominant disease that affects 1 in 3,000 persons worldwide. Café-au-lait macules and peripheral nerve sheath tumors (ie, neurofibromas) are the most commonly recognized manifestations of NF-1. However, NF-1 affects multiple organ systems, and a multidisciplinary approach to treatment is required. Management of the orthopaedic manifestations of NF-1 is often difficult. The most complex manifestations are scoliosis (dystrophic and nondystrophic), congenital pseudarthrosis of the tibia, and problems related to soft-tissue tumors. Metabolic bone disease is common; many patients are frankly osteopenic, which further complicates treatment. Dystrophic scoliosis, which may be caused by either bony dysplasia or intraspinal pathology, is characterized by early presentation and rapid progression. Pseudarthrosis is common even after instrumented fusion. Nondystrophic scoliosis tends to behave like adolescent idiopathic scoliosis, although it may present earlier and is associated with a higher rate of pseudarthrosis. Congenital pseudarthrosis of the tibia is a long-bone dysplasia that afflicts patients with NF-1. Management of this osseous deformity is challenging. Failure to achieve union and refracture are common.

RESUMO

BACKGROUND: To our knowledge, no study to date has compared the use of spinal and general anesthesia in patients undergoing operative fixation of an unstable ankle fracture. The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients. METHODS: Between October 2000 and November 2006, 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively. Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia. All patients were evaluated at three, six, and twelve months postoperatively with use of standardized, validated general and limb-specific outcome instruments. Standard and multivariable analyses comparing outcomes at these intervals were performed. RESULTS: Four hundred and sixty-six patients (93%) who had been followed for a minimum of one year met the inclusion criteria. Compared with the general anesthesia group, the spinal anesthesia group had a greater mean age (p = 0.005), higher classification on the American Society of Anesthesiologists system (p = 0.03), and a greater number of patients with diabetes (p = 0.02). There was no difference in sex distribution between the groups. At three months, patients who received spinal anesthesia had significantly better pain scores (p = 0.03) and total scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 0.02). At six months, patients in the spinal anesthesia group continued to have better pain scores (p = 0.04), but there was no longer a difference in total scores (p = 0.06). At twelve months, no difference was detected between the groups in terms of functional or pain scores. There was no difference in complication rates between the groups. CONCLUSIONS: Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period. We recommend that, unless there is a specific contraindication, patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture.

RESUMO

Femoral neck fractures in young patients are a relatively rare event and are often the consequence of a high-energy injury. Concomitant injuries are present more than 50% of the time. Previous reports have found the rate of nonunion and avascular necrosis in this population to be as high as 35% and 45%, respectively. The salvage options, which tend to yield more acceptable results in elderly patients with femoral neck fractures, yield disproportionately poor results in young, active patients who are often productive members of the labor force. Many reports exist in the literature evaluating the various treatment options of these injuries. This review will address the epidemiology and diagnosis of the injury. In addition, the various treatment options in the acute presentation, as well as options available for treating the sequelae of femoral neck fractures in the young, will be discussed. Although longer life expectancy and the sustained activity level of many people previously considered elderly has blurred the definition of "young," this review will use the available literature dealing with skeletally mature patients up to the age of 60 years.

RESUMO

PURPOSE: To prospectively compare the efficacy of 2-octylcyanoacrylate (Dermabond; Ethicon Inc, Somerville, NJ) with standard suture repair in the management of nail bed lacerations. METHODS: Forty consecutive patients with acute nail bed lacerations were enrolled in this study. Eighteen patients were randomized to nail bed repair using Dermabond (2-octylcyanoacrylate), and 22 were randomized to standard repair using 6-0 chromic suture. At presentation, demographic information and laceration characteristics were recorded. The time required for nail bed laceration repair with each method was documented, and cosmetic and functional outcomes were assessed at 1, 3, and 6 months after injury. Comparisons between treatment groups were made using unpaired Student's t-tests. RESULTS: The Dermabond repair group was composed of 10 males and 8 females with a mean age of 32.3 years. The suture repair group was composed of 17 males and 5 females with a mean age of 29.5 years. The mean follow-up was 5.1 months (range 4-11 months) and 4.8 months (range 4-11 months) for the Dermabond group and suture group, respectively. There was no difference between the two treatment groups with respect to age, comorbidities, and length of follow-up (p>.05). The average time required for nail bed repair using Dermabond was 9.5 minutes, which was significantly less than that required for suture repair (27.8 minutes) (p<.0003). At each follow-up time point, there was no statistical difference in physician-judged cosmesis, patient-perceived cosmetic outcome, pain, or functional ability between the Dermabond and suture treatment cohorts (p>.05). CONCLUSIONS: Nail bed repair performed using Dermabond is significantly faster than suture repair, and it provides similar cosmetic and functional results. In the management of acute nail bed lacerations, Dermabond is an efficient and effective repair technique. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

RESUMO

Recognizing the issues created in dealing with human body parts because of medical advances, the authors examine how the law has treated and currently treats tissues, cells, and gametes. In this examination, the authors discuss why the law should recognize property interests in tissues, cells, and gametes and how it might do so.
