Operative fixation of rib fracture nonunions.

INTRODUCTION: Rib fractures are common injuries in trauma patients that often heal without intervention. Infrequently, symptomatic rib fracture nonunions are a complication after rib fractures. There is a paucity of literature on the surgical treatment of rib fracture nonunion. The purpose of this study was to describe the efficacy of rib fracture nonunion operative fixation with particular focus on surgical technique, healing rates, and complications. MATERIALS AND METHODS: Patients aged ≥ 18 years with symptomatic rib fracture nonunions treated with open reduction and internal fixation (ORIF) with locking plates at a single urban level 1 trauma center were retrospectively reviewed. Pertinent demographic, clinical, radiographic, and surgical data were collected and analyzed. RESULTS: A total of 18 patients met inclusion criteria. The mean time from injury to undergoing ORIF for rib fracture nonunion was just under a year and the number of ribs plated was 2.95 ± 1.16 (1-5 ribs) with bone grafting used in six cases. All patients (100%) showed evidence of healing at an average of 2.65 ± 1.50 months (2-8 months). All patients reported a decrease in pain. No narcotic pain medication was used at an average of 3.88 ± 3.76 weeks (0-10 weeks) post-operatively. Intraoperative and postoperative complications were found in 4 (22.2%) patients. CONCLUSION: This study concluded that operative fixation of symptomatic rib fracture nonunion demonstrated favorable outcomes with reduction in preoperative pain levels, decreased use of narcotic pain medication, minimal complications, and a high rate of fracture union. This described method provides symptomatic relief, reduction in pain, and promotes bony healing of the fracture nonunion without development of major complications. We suggest that operative fixation should be considered as the primary method of treatment of symptomatic rib nonunions.

First Extensor Compartment Tendon Rupture in the Setting of a Radial Styloid and Both-Bone Forearm Fracture: A Case Report.

CASE: We report on the rare occurrence of first extensor compartment tendon injury at the myotendinous junction after fractures of the radial styloid and both-bone forearm in a healthy 59-year-old man. Here, a novel technique for repair of this unique injury and an additional proposed mechanism of tendon rupture are discussed. CONCLUSION: We advocate for the suspicion of tendon rupture in the first dorsal compartment with fractures of the radial styloid and both-bone forearm. Tubularization and transfer of the abductor pollicis longus and extensor pollicis brevis tendons to the brachioradialis muscle may be of benefit in these patients.

Midshaft clavicle fractures with associated ipsilateral acromioclavicular joint dislocations: Incidence and risk factors.

INTRODUCTION: Simultaneous ipsilateral clavicle and acromioclavicular (AC) joint injury have been infrequently reported in the literature at this time. The purpose of this study was to assess incidence as well as assess risk factors for this dual injury pattern. METHODS: We performed a retrospective review of a prospectively collected database (Level III evidence), evaluating 383 adult patients without previous shoulder girdle injury or trauma with a minimum 1-year follow-up who sustained a displaced diaphyseal clavicle fracture. All patients in the study underwent either nonoperative management or surgical reduction and stabilization of a diaphyseal clavicle fracture with a plate and screw construct. Study subjects were followed with serial radiographs. Clavicle and shoulder radiographs, as well as chest radiographs and contralateral films in questionable cases, were used to assess for acromioclavicular joint injury in both operative and nonoperative groups. Additional data was collected on concurrent injuries, patient demographics, fracture characteristics, fixation techniques, surgical/post-operative data, and operative or nonoperative treatment. RESULTS: We found that 13/183 (7.1%) of patients undergoing fixation of a diaphyseal clavicle fracture had an ipsilateral AC joint injury, while 13/200 (6.5%) of patients undergoing conservative management had an ipsilateral AC joint injury. Critical analysis of the data revealed that presence of ipsilateral scapular body fractures, and a likely incidental association with superior plating fixation, were associated with an increased rate of this injury pattern. CONCLUSIONS: Ipsilateral clavicle fracture and AC joint injury is much more common than traditionally believed, with an incidence of 6.8% overall. It is unknown how the presence of an associated AC injury influences outcome, as AC injury was not universally symptomatic.

Clinical Outcomes of Surgical Stabilization of Flail Chest Injury.

INTRODUCTION: Recent reported success in surgical stabilization of flail chest has been described in small series, but scant evidence exists for this procedure in the orthopaedic literature. METHODS: We reviewed 88 consecutive patients who underwent surgical stabilization of flail chest, along with 88 consecutive patients with flail chest who underwent traditional closed management before initiation of our algorithm change to surgical management. RESULTS: Surgical stabilization of flail chest injuries led to statistically significant decreases in hospital length of stay, ventilator-dependency time, pneumonia, tracheostomy, and mortality rate. In addition, the presence of pulmonary contusion did not eliminate the significant improvements in the aforementioned variables. DISCUSSION: Surgical stabilization of flail chest with modern techniques and implants provides significant improvements in both mortality and short-term outcomes. Although pulmonary contusion decreased overall outcomes across both cohorts, this factor did not alter the ability of rib fixation to improve outcomes.

Equivalent outcomes after coronary artery bypass graft surgery performed by consultant versus trainee surgeons: A systematic review and meta-analysis.

OBJECTIVE: In recent years, concerns have been raised about the learning opportunities available to cardiac surgical trainees. This meta-analysis was conducted to assess the impact of trainee operator status on clinical outcomes after coronary artery bypass graft (CABG) surgery. METHODS: Medline, EMBASE, and the Cochrane Library were systematically searched for studies that reported CABG outcomes according to the training status of the primary operator (consultant vs trainee). Data were independently extracted by 2 investigators; a meta-analysis was conducted according to predefined clinical endpoints. RESULTS: Sixteen observational studies (n = 52,966) met criteria for inclusion, with 8 studies (n = 36,479) reporting propensity-adjusted analyses. Trainee cases were associated with increased aortic crossclamp duration (mean difference: 4.80; 95% confidence interval [CI], 0.76-8.83) and cardiopulmonary bypass duration (mean difference: 4.24; 95% CI, 0.00-8.47). Perioperative mortality was similar for CABG performed primarily by trainees versus consultants (odds ratio 0.98; 95% CI, 0.81-1.18). No significant difference was found in the incidence of perioperative stroke, myocardial infarction, acute renal failure, reoperation for bleeding, or wound infection. Trainee operator status was not associated with increased midterm mortality (hazard ratio 1.00; 95% CI, 0.90-1.11). In subgroup analysis that included 5 studies and 8025 patients, off-pump CABG trainee cases were not associated with increased perioperative mortality or morbidity. CONCLUSIONS: With appropriate supervision, conventional CABG can be performed by trainee surgeons without an adverse impact on perioperative outcomes or midterm survival. Data regarding off-pump CABG are limited, and further research is warranted to ascertain the impact of trainee operator status on long-term outcomes after off-pump CABG.

Treatment of acetabulum fractures through the modified Stoppa approach: strategies and outcomes.

BACKGROUND: Since the original description by Letournel in 1961, the ilioinguinal approach has remained the predominant approach for anterior acetabular fixation. However, modifications of the original abdominal approach described by Stoppa have made another option available for reduction and fixation of pelvic and acetabular fractures. QUESTIONS/PURPOSES: We evaluated our results in patients with acetabulum fractures with the modified Stoppa approach in terms of (1) hip function as measured by the Merle d'Aubigne hip score; (2) complications; and (3) quality of fracture reduction and percentage of fractures that united. METHODS: Between September 2008 and August 2012, 289 patients with acetabular fractures were treated at our Level I trauma center. Twelve percent (36 of 289) of patients were treated operatively using the modified Stoppa approach. Ninety-seven percent (35 of 36) of our patients had fracture patterns involving displacement of the posterior column. Six (17%) were converted early to a total hip arthroplasty, and 14 (39%) were lost to final followup, leaving 22 of 36 for subjective clinical outcome analysis at a mean of 32 months (range, 9-59 months). Our general indications for this approach during the period in question were fractures of the anterior column and anterior wall, anterior column with posterior hemitransverse fractures, both column fractures, transverse fractures, and T-type fractures. Followup included regularly scheduled office visits with radiographs (AP pelvis, Judet views) that were graded by the treating surgeon and by the authors of this study (MJI, BCT) and patient outcome surveys. RESULTS: Merle d'Aubigne hip scores were very good in 55% (12 of 22), good in 9% (two of 22), medium in 18% (four of 22), fair in 5% (one of 22), and poor in 14% (three of 22), and 70% (23 of 33) of patients were able to ambulate without any assistive devices. Complications included one superficial infection and three deep infections, two patients with temporary lateral thigh numbness, no obturator nerve palsies, and one inguinal hernia. Three deaths in the cohort were seen in followup as a result of unrelated causes. Radiographic grading of fracture reductions after surgery revealed that 27 (75%) were anatomic, six (17%) were satisfactory, and three (8%) were unsatisfactory. A total of 94% of the fractures united. CONCLUSIONS: In agreement with prior published data, our results show good functional outcomes with minimal complications using the modified Stoppa approach for a variety of acetabular fractures. Our results highlight the difficulty but feasibility in treating posterior column displacement through an anterior approach. Consideration for dual approaches with posterior column involvement may be warranted to optimize fracture reduction and functional outcomes. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Plating of patella fractures: techniques and outcomes.

Operative treatment of displaced patella fractures with tension band fixation remains the gold standard, but is associated with a significant rate of complications and symptomatic implants. Despite the evolution of tension band fixation to include cannulated screws, surprisingly little other development has been made to improve overall patient outcomes. In this article, we present the techniques and outcomes of patella plating for displaced patella fractures and patella nonunions.

Surgical approaches for rib fracture fixation.

Operative management of thoracic injuries is an increasingly accepted technique, with multiple reports of improved patient outcomes as compared with nonoperative treatment. Despite the evolving support of rib fracture fixation, descriptions of surgical approaches and tactics remain limited. We present this information to allow surgeons to begin or improve treatment of these injuries. In addition, we present the initial treatment results of a series of 21 patients treated with the approaches described within.

Successful treatment of a recalcitrant pleural effusion with rib fracture fixation.

Pulmonary complications of rib fractures typically occur in the immediate postinjury period, as a result of the forces causing the injury or subsequent rib fracture displacement. Pneumothorax, hemothorax, pulmonary contusions, or parenchymal lacerations are frequently seen with significant chest wall trauma. Hemopneumothorax is typically treated with tube thoracostomy, and full resolution of the pleural injury is expected; continued pleural fluid accumulation despite these measures is unanticipated, rare, and quite problematic. We report a case of hemorrhagic pleural effusion after rib fractures that were recurrent despite several tube thoracostomies and computed tomography-guided aspirations. The patient subsequently underwent operative fixation of her rib fractures, with successful resolution of her symptomatic pleural effusion.

Gritti-stokes amputations in the trauma patient: clinical comparisons and subjective outcomes.

BACKGROUND: The Gritti-Stokes amputation procedure is a modification of the traditional transfemoral amputation, with resection of the bone at a supracondylar femoral level and fixation of the patella to the distal part of the femur as an end-cap. Although well-established in patients with vascular compromise, no evidence exists on its use in the trauma setting. METHODS: Fourteen consecutive patients who underwent Gritti-Stokes amputation and fifteen consecutive patients who underwent traditional transfemoral amputation by fellowship-trained orthopaedic traumatologists at a level-I trauma center were evaluated at more than fourteen months postoperatively. The Sickness Impact Profile (SIP) questionnaire was also administered to both patient groups at more than thirty-six months postoperatively to assess patient-reported functional outcomes. RESULTS: Despite the two groups not having significant differences in preoperative variables or demographics, the Gritti-Stokes group had significantly improved SIP questionnaire overall and domain scores. This procedure also left the patients with a significantly longer residual limb (an average of 46.1 cm of residual femoral length versus 34.6 cm for the transfemoral group). The Gritti-Stokes group also had a significantly increased rate of walking without assistive devices (five patients versus none in the transfemoral amputation group). CONCLUSIONS: The Gritti-Stokes amputation appears to be safe and beneficial when utilized in the trauma population.

Induced membrane technique for reconstruction to manage bone loss.

Multiple surgeries are often required to manage segmental bone loss because of the complex mechanics and biology involved in reconstruction. These procedures can lead to prolonged recovery times, poor patient outcomes, and even delayed amputation. A two-stage technique uses induced biologic membranes with delayed placement of bone graft to manage this clinical challenge. In the first stage, a polymethyl methacrylate spacer is placed in the defect to produce a bioactive membrane, which appears to mature biochemically and physically 4 to 8 weeks after spacer placement. In the second, cancellous autograft is placed within this membrane and, via elution of several growth factors, the membrane appears to prevent graft resorption and promote revascularization and consolidation of new bone. Excellent clinical results have been reported, with successful reconstruction of segmental bone defects >20 cm.

Plating of acute humeral diaphyseal fractures through an anterior approach in multiple trauma patients.

OBJECTIVE: We evaluated the clinical and long-term functional outcomes of humeral diaphyseal fractures treated with acute anterior plating in a trauma population. DESIGN: Single-center, retrospective cohort analysis with long-term prospective follow-up. SETTING: Urban, Level I trauma center. PATIENTS: Ninety-six patients with high-energy fractures of the humeral shaft were treated over a 10-year period. INTERVENTION: All patients were treated by a standard surgical protocol of open reduction through an anterior approach with small or large fragment fixation in the supine position. MAIN OUTCOME MEASUREMENTS: Mechanism of injury, time to union, complications, and range of motion during clinical follow-up were obtained. We also prospectively assessed long-term strength, range of motion, and perceptions of disability using the Disabilities of the Arm, Shoulder and Hand questionnaire. RESULTS: Mean time to surgery was 5 days (standard deviation, 11 days); 97.5% of patients achieved union in an average of 16.9 weeks (range, 6-56 weeks). Complications included two postoperative infections, two nonunions, and three implant failures. Long-term follow-up (n = 34) averaged 4.75 years (range, 1.4-10.8 years). On average, no significant differences between the injured and uninjured extremities were seen in range of motion at the shoulder and elbow with the exception of shoulder flexion. A modest loss of upper extremity strength in the injured arm was appreciated. The mean Disabilities of the Arm, Shoulder and Hand score was 25.9 (range, 0-79). CONCLUSIONS: A standard anterior surgical approach with small fragment fixation is a safe and effective treatment for humeral shaft fractures in multiple trauma patients. We show a high union rate and few complications, although a modest loss of function and some perceived disability exists in the long-term.

Gritti-Stokes Amputation in the Trauma Patient: Tips and Techniques.

INTRODUCTION: The Gritti-Stokes amputation establishes osseous continuity between the patella and the distal part of the femur with maintenance of the intact prepatellar soft tissues. STEP 1 PREOPERATIVE PLANNING: As with all orthopaedic surgery, preoperative planning is essential to obtaining an optimal outcome with this procedure. STEP 2 FLAP DESIGN: Use an asymmetric flap consisting of the undisturbed prepatellar soft tissues and rotate it posteriorly to achieve closure. STEP 3 SOFT-TISSUE DISSECTION: Keep soft-tissue dissection subperiosteal or intratendinous to minimize blood loss and postoperative pain. STEP 4 DISTAL FEMORAL AND PATELLAR CUTS: Use a high-speed saw to transect the femur and patella. STEP 5 POSTERIOR DISSECTION: Carry out posterior dissection in a methodical manner, with individual identification and ligation of all neurovascular structures. STEP 6 PATELLOFEMORAL ARTHRODESIS: Suture the patella to the distal part of the femur using six drill holes and nonabsorbable suture. STEP 7 SOFT-TISSUE CLOSURE: Close the remaining soft tissue, including the posterior musculature, subcutaneous layer, and skin, in a layered fashion. STEP 8 POSTOPERATIVE MANAGEMENT: Postoperative care should be done in conjunction with a prosthetist to obtain optimal outcomes. RESULTS: The Gritti-Stokes amputation technique appears to be a potentially valuable addition to the amputation surgeon's armamentarium.

Medial malleolar fractures: a biomechanical study of fixation techniques.

Fracture fixation of the medial malleolus in rotationally unstable ankle fractures typically results in healing with current fixation methods. However, when failure occurs, pullout of the screws from tension, compression, and rotational forces is predictable. We sought to biomechanically test a relatively new technique of bicortical screw fixation for medial malleoli fractures. Also, the AO group recommends tension-band fixation of small avulsion type fractures of the medial malleolus that are unacceptable for screw fixation. A well-documented complication of this technique is prominent symptomatic implants and secondary surgery for implant removal. Replacing stainless steel 18-gauge wire with FiberWire suture could theoretically decrease symptomatic implants. Therefore, a second goal was to biomechanically compare these 2 tension-band constructs. Using a tibial Sawbones model, 2 bicortical screws were compared with 2 unicortical cancellous screws on a servohydraulic test frame in offset axial, transverse, and tension loading. Second, tension-band fixation using stainless steel wire was compared with FiberWire under tensile loads. Bicortical screw fixation was statistically the stiffest construct under tension loading conditions compared to unicortical screw fixation and tension-band techniques with FiberWire or stainless steel wire. In fact, unicortical screw fixation had only 10% of the stiffness as demonstrated in the bicortical technique. In a direct comparison, tension-band fixation using stainless steel wire was statistically stiffer than the FiberWire construct.

Use of the trauma pelvic orthotic device (T-POD) for provisional stabilisation of anterior-posterior compression type pelvic fractures: a cadaveric study.

OBJECTIVE: To demonstrate that a commercially available pelvic binder the trauma pelvic orthotic device (T-POD) is an effective way to provisionally stabilise anterior-posterior compression type pelvic injuries. METHODS: Rotationally unstable pelvic injuries were created in 12 non-embalmed human cadaveric specimens. Each pelvis was then stabilised first with a standard bed sheet wrapped circumferentially around the pelvis and held in place with a clamp. After recreating the symphyseal diastasis, the pelvis was stabilised with the T-POD. Reduction of the symphyseal diastasis was assessed by comparing measurements obtained via pre- and post-stabilisation AP radiographs. RESULTS: The mean symphyseal diastasis was reduced from 39.3mm (95% CI 30.95-47.55) to 17.4mm (95% CI -0.14 to 34.98) with the bed sheet, and to 7.1mm (95% CI -2.19 to 16.35) with the T-POD. CONCLUSIONS: Although both a circumferential sheet and the T-POD were able to decrease symphyseal diastasis consistently, only the T-POD showed a statistically significant improvement in diastasis when compared to injury measurements. In 75% of the cadaveric specimens (9 of 12), the T-POD was able to reduce the symphysis to normal (<10mm diastasis). Both a circumferential sheet and the T-POD are effective in provisionally stabilising Burgess and Young anterior-posterior compression II type pelvic injuries, but the T-POD is more effective in reducing symphyseal diastasis.

Does medial tenderness predict deep deltoid ligament incompetence in supination-external rotation type ankle fractures?

OBJECTIVE: To identify whether medial tenderness is a predictor of deep deltoid ligament incompetence in supination-external rotation ankle fractures. DESIGN: All Weber B lateral malleolar fractures with normal medial clear space over a 9 month period were prospectively included in the study. Fracture patterns not consistent with a supination-external rotation mechanism were excluded. SETTING: High-volume tertiary care referral center and Level I trauma center. PATIENTS/PARTICIPANTS: Fifty-five skeletally mature patients with a Weber B lateral malleolar fracture and normal medial clear space presenting to our institution were included. INTERVENTION: All study patients had ankle anteroposterior, lateral, and mortise radiographs. Each patient was seen and evaluated by an orthopedic specialist and the mechanism of injury was recorded. Each patient was assessed for tenderness to palpation in the region of the deltoid ligament and then had an external rotation stress mortise radiograph. MAIN OUTCOME MEASURE: Correlating medial tenderness with deep deltoid competence as measured by stress radiographs. RESULTS: Thirteen patients (23.6%) were tender medially and had a positive external rotation stress radiograph. Thirteen patients (23.6%) were tender medially and had a negative external rotation stress radiograph. Nineteen patients (34.5%) were nontender medially and had a negative external rotation stress radiograph. Ten patients (18.2%) were nontender medially and had a positive external rotation stress radiograph. We calculated a chi statistic of 2.37 as well as the associated P value of 0.12. Medial tenderness as a measure of deep deltoid ligament incompetence had a sensitivity of 57%, a specificity of 59%, a positive predictive value of 50%, a negative predictive value of 66%, and an accuracy of 42%. CONCLUSION: There was no statistical significance between the presence of medial tenderness and deep deltoid ligament incompetence. There is a 25% chance of the fracture in question with medial tenderness having a positive external rotation stress and a 25% chance the fracture with no medial tenderness having a positive stress test. Medial tenderness in a Weber B lateral ankle fracture with a normal clear space on standard plain radiographs does not ensure the presence of a positive external rotation stress test.
