RESUMO

Compared with hip and knee arthroplasty, total elbow arthroplasty (TEA) has a higher complication rate and lower survivorship. Modern TEA implants most commonly require revision due to implant loosening, infection, and periprosthetic fracture. Concerns with revision TEA include handling of the soft tissues and possible necessity of flap coverage, triceps management, preservation of bone stock, and management of concurrent infection or fracture. In this review, we will discuss preoperative evaluation of the failed elbow arthroplasty, surgical approaches, techniques for revision, outcomes, and complications following revision total elbow arthroplasty.

RESUMO

PURPOSE: Hand and wrist injuries are common among competitive athletes and can have a substantial impact on playing time and future participation. The purpose of this study was to provide epidemiological data from the National Collegiate Athletic Association Injury Surveillance Program to correlate injury diagnosis with the need for surgery and time loss. METHODS: Using the National Collegiate Athletic Association Injury Surveillance Program, this retrospective study extracted data of hand and wrist injuries for all 25 National Collegiate Athletic Association sports from the academic years 2004-2005 to 2013-2014. The "severe" category was defined as injuries resulting in the following: (1) surgery, (2) season-ending status, or (3) more than 30 days of playing time loss. The epidemiologic data included injury rate per 100,000 athlete exposures (defined as 1 athlete participating in 1 practice or competition) based on diagnoses and demographic information such as sports and sex. We used a Poisson regression model to estimate the incidence rate and 95% confidence interval. RESULTS: Overall, 4,851 hand injuries were identified, with an injury rate of 41.2 per 100,000 athlete exposures. The most common diagnoses were metacarpal or phalangeal fractures (19.9%), lacerations or contusions (15.4%), and wrist sprains (14.7%). The surgical rate was 9.6%, and the season-ending rate was 5.8%. Severe injuries occurred in 17.5% of the hand and wrist injuries; within this subset, the most common diagnoses included metacarpal or phalangeal fractures (43.8%), scaphoid fractures (12.8%), and thumb ulnar collateral ligament tears (8.7%). Scaphoid fractures and metacarpal or phalangeal fractures had the highest surgical rate and season-ending rate among all the injuries. CONCLUSIONS: The injury rate of hand and wrist injuries is comparable with those of other common sports injuries. Approximately one fifth of the injuries were considered severe, which led to a high surgical rate, and these had a considerable impact on the athletes' ability to finish the season. TYPE OF STUDY/LEVEL OF EVIDENCE: Outcome research level II.

RESUMO

PURPOSE: Inconsistent outcomes have been reported in several prior studies of elderly patients with distal humerus fractures treated with open reduction and internal fixation (ORIF). We evaluated the outcomes of ORIF using modern precontoured plates exclusively in a parallel orientation. METHODS: A retrospective review was performed to identify the patients aged over 65 years who sustained an isolated distal humerus fracture between 2015 and 2019. We identified 22 patients who underwent distal humerus ORIF using parallel, precontoured locking plates. Electronic medical records were reviewed for demographic characteristics, physical examination findings, and radiographic data. Outcomes were assessed with Quick Disabilities of the Arm, Shoulder, and Hand scores and Mayo Elbow Performance scores. Complications were evaluated by a review of the patient's medical record and postoperative radiographs. RESULTS: Of the included patients, 18 were women and 4 were men; the average age was 78 years (SD, 8.5 years), and the patients were followed for an average of 33 months. The sample consisted of 19 AO type C, 1 type B, and 2 type A fractures. At the final follow-up, the mean arc of total elbow flexion was 107° (SD, 18.9°; range 40° to 130°), with mean elbow flexion of 129° (SD, 11.7°; range, 120° to 140°) and mean extension of 22° (SD, 12.9°; range 0° to 90°). The mean Quick Disabilities of the Arm, Shoulder, and Hand score was 19 (SD, 14.4), and the mean Mayo Elbow Performance score was 86 (SD, 10.2). Complications occurred in 5 (23%) patients, requiring 4 subsequent surgeries, of which 1 was a conversion to total elbow arthroplasty. CONCLUSIONS: Older patients who underwent ORIF of the distal humerus using a parallel construct demonstrated good functional outcomes and similar complications to those in previously reported studies. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

RESUMO

BACKGROUND: Despite surgical fixation, the scaphoid nonunion rate remains at 3% to 5%. Recent biomechanical studies have demonstrated increased stability with 2-screw constructs. The objective of our study is to determine the preliminary union rate and anatomic feasibility of 2-screw surgical fixation for scaphoid fractures. METHODS: This study is a retrospective case series of 25 patients (average age 32 years) with scaphoid fractures treated with 2 parallel headless compression screws (HCS). Postoperative evaluation included Mayo Wrist Score (MWS), range of motion, time to union, and return to activity. Bivariate analysis for gender and Pearson correlation coefficient for body size (height, weight, and body mass index) was conducted against radiographically measured scaphoid width, screw lengths, and the distance between the 2 screws. RESULTS: All fractures healed with an average time to union of 9.9 weeks (median 7.6 weeks; range: 4.1-28.3). The mean MWS was 93.3 (range: 55-100), with 3 complications (12%), one of which affected the outcome of the surgery. The bivariate analysis demonstrated that the female gender was associated with significantly smaller scaphoid width (P = .004) but a similar distance between the 2 screws (P = .281). The distance between the 2 screws and the body size demonstrated a weak-to-no correlation. CONCLUSIONS: The 2-screw construct for scaphoid fracture achieved a favorable union rate and clinical outcome. Gender was the only variable significantly associated with scaphoid width and screw length. The distance between the screws was constant regardless of gender and body size, indicating that the technique for parallel screw placement can remain consistent. TYPE OF STUDY: Therapeutic. LEVEL OF EVIDENCE: Level IV.

RESUMO

Monteggia fractures classically involve a proximal ulna fracture with an associated radial head dislocation. The presence of radial head/neck fracture and comminution of the proximal ulna with coronoid involvement elevates the complexity of surgical reconstruction considerably. The Jupiter classification captures this injury pattern as a subgroup of Bado posterior Monteggia lesions. Access to the critical coronoid fragment can be problematic from the posterior approach and may result in tenuous reduction and fixation, directly affecting the functional outcome. Multiple operative techniques have been described to address the broad spectrum of injuries seen in Monteggia fractures. This article will cover commonly used fixation techniques for Monteggia fractures with a comprehensive literature review, including technical tips, outcomes, and complications.

RESUMO

Monteggia fractures involve proximal ulna fracture associated with a radiocapitellar joint dislocation. The Bado classification is primarily based on the direction of the radial head dislocation. The Jupiter subtype classification of Bado II fractures further characterizes the severity of proximal ulna comminution and the involvement of the coronoid fragment. This latter classification can better prognosticate the challenges of surgical reconstruction and clinical outcomes. Surgery for all adult Monteggia fractures is required to restore the anatomic alignment of the ulna, which indirectly reduces the radiocapitellar joint. The complexity of the injury is considerably increased by comminution of the proximal ulna, the degree of radial head fragmentation, the reduction of the radial head, and ulnohumeral instability. Anatomic reduction is considered critical to achieving a favorable outcome.

RESUMO

Intra-articular distal humerus fractures with an associated coronal shear capitellar fragment present a challenge for stable internal fixation. Adequate visualization and fixation of the capitellar shear fragment are difficult to achieve with conventional exposures, including the olecranon osteotomy. The capitellar fragment often translates anterior and proximally and is challenging to visualize with intact soft tissue attachments from a posterior approach. We describe a surgical exposure that releases the lateral ulnar collateral ligament in addition to an olecranon osteotomy to allow complete visualization of the entire articular surface. In contrast to an isolated capitellar fracture, the column stability and the posterior cortex are frequently disrupted with distal humerus fractures. Depending on the comminution of the posterior cortex, a supplemental posterolateral plate or headless compression screws can provide fixation to the coronal fracture plane. The lateral ulnar collateral ligament is repaired at the conclusion of fracture stabilization through a bone tunnel or to the plate to restore lateral stability. Despite the release of the ligament and additional soft tissue stripping, there were no cases of elbow instability or avascular necrosis in our case series of 9 patients.

RESUMO

PURPOSE: Wikipedia is a popular online encyclopedia generating over 5.4 billion visits per month, and it is also a common resource for the general public and professionals for medical information. The goal of this study is to determine the accuracy and completeness of Wikipedia as a resource for musculoskeletal anatomy. METHODS: The origin, insertion, innervation, and function of all muscles of the upper and lower extremities as detailed on Wikipedia was compared to the available corresponding information in Grant's Atlas of Anatomy (14th edition). Entries were scored for both accuracy and completeness. Descriptive statistics were calculated and associations between and within entries for accuracy and completeness were assessed by McNemar's tests. Information on Wikipedia's references was also collected. RESULTS: Overall, data on Wikipedia was 97.6% complete and 98.8% accurate when compared to Grant's Atlas of Anatomy. 78.6% of all entries were fully complete and accurate, with 15.3% of entries containing one error and 6.1% containing two errors. There were no associations between or within entries' accuracy and completeness. Only 62% of references from Wikipedia included were from academic sources. CONCLUSIONS: Musculoskeletal anatomy entries on Wikipedia are imperfect; they have inaccurate and missing information. Furthermore, a considerable proportion of references cited in entries are from poorly identified sources. While Wikipedia is an easily accessible resource for a large number of people and much of the anatomic information is appropriate, it cannot be considered to be an equivalent resource when compared to anatomic texts.

RESUMO

BACKGROUND: The purpose of this investigation was to compare the presentation and postoperative results of children treated for open and closed, completely displaced type III supracondylar humerus fractures (SCFs). METHODS: Thirty patients with open and 66 patients with closed, completely displaced type III SCFs were evaluated. Open fractures underwent irrigation and debridement, and all patients were treated by open or closed reduction and pin fixation. Medical records were reviewed to obtain demographic information as well as preoperative and postoperative clinical data regarding mechanism of injury, neurovascular status, associated injuries, postoperative range of motion, infections, and pain. Radiographs were evaluated to quantify displacement, Baumann's angle, humeral capitellar angle, position of the anterior humeral line, and adequacy of reduction. Outcomes were assessed using Flynn criteria. Mean clinical follow-up for the open and closed fracture groups was 8.9 and 5.7 months, respectively. RESULTS: Both groups were similar with respect to age, sex distribution, weight and body mass index, laterality of involvement, and mechanism of injury. At presentation, 35% of closed SCFs and 23% of open SCFs presented with abnormal neurovascular status. There was a higher prevalence of diminished/absent pulses or distal limb ischemia in patients with open injuries (27%) compared with closed fractures (18%). Conversely, severely displaced closed fractures were more commonly associated with nerve injury/palsy at presentation (35%) than those with open fractures (23%). Spontaneous nerve recovery was seen in 87% within 3 to 6 months. Postoperative loss of reduction and malunion were more common in the closed fracture group. However, 84% of patients achieved good-to-excellent results by Flynn criteria, with no appreciable difference based upon open versus closed fractures. CONCLUSIONS: With timely wound and fracture treatment, the clinical and radiographic results of children treated for open SCFs is similar to those with closed type III injuries, with little increased risk for infection, malunion, or neurovascular compromise. LEVEL OF EVIDENCE: Level III.

RESUMO

BACKGROUND: Open reduction and internal fixation (ORIF) of the clavicle is a common procedure that has been shown to have improved outcomes over nonoperative treatment. Several incisions can be used to approach clavicle fractures, the decision of which is variable among surgeons. PURPOSE: To compare patient satisfaction and subjective outcomes between patients with a longitudinal incision versus those with a necklace incision for the treatment of diaphyseal clavicle fractures. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Thirty-six patients with a diaphyseal clavicle fracture (Orthopaedic Trauma Association type 15-B) were treated by 1 of 7 orthopaedic surgeons. The intervention was ORIF with anatomic contoured plates. Patients were divided into a necklace incision group and a longitudinal incision group depending on the surgical approach used. Medical records were reviewed, and participants completed an online survey with questions related to pain, numbness, scar appearance, and satisfaction. Function was assessed using the American Shoulder and Elbow Surgeons score. Statistical significance was determined with P < .05. RESULTS: There were 16 patients in the necklace incision group and 20 in the longitudinal incision group. Patients in the necklace incision group were significantly more satisfied with the appearance of their scars (P = .01), which correlated with overall satisfaction (P = .05). There were no differences in overall satisfaction, pain, numbness, or reoperation rates for hardware removal between the necklace (6%) and longitudinal groups (15%). CONCLUSION: Patients undergoing clavicle ORIF with a necklace incision are more satisfied with their scar appearance than those with a longitudinal incision. The overall satisfaction, rate of numbness, and plate removal were similar in both groups.

RESUMO

The purpose of this investigation was to determine the incidence and identify the predictors of carpal tunnel release (CTR) after open fractures of the distal radius (DRF). Patients with clinical symptoms of persistent median nerve neuropathy that required CTR were analyzed for risk factors. One hundred thirty-nine open DRFs (107 grade I, 23 grade II, 9 grade III) met the inclusion criteria. The incidence of CTR was 13.7% in all open DRFs (19 out of 139). Multivariable logistic regression analysis identified four predictors: male sex [odds ratio (OR) = 8.8, p = .001], type III Gustilo and Anderson grade (OR = 6.2, p = .04), OTA fracture type C (OR = 3.8, p = .03), and the application of external fixation (OR = 14.0, p D .02). The probability of CTR, determined by preoperative variables, was 80% with three factors present and 2% with no risk factors. High-risk patients may be identified who may benefit from closer perioperative surveillance and possibly carpal tunnel release. (Journal of Surgical Orthopaedic Advances 26(4):227-232, 2017).

RESUMO

PURPOSE: A high incidence of nonunion and relatively poor outcomes with prior fixation techniques has precluded scapholunate (SL) arthrodesis as a standard treatment for SL instability. Our purpose was to determine the impact on range of motion (ROM) of simulated SL arthrodesis via headless screw fixation. METHODS: We performed baseline wrist ROM for 10 cadaveric wrists using a standardized mounting-and-weights system. Extension, flexion, radial deviation, ulnar deviation, dart-thrower's extension, and dart-thrower's flexion were assessed. Two 3.0-mm headless compression screws were inserted across the SL joint to simulate SL arthrodesis. Goniometric measurements and fluoroscopic imaging were repeated to assess ROM differences after simulated SL arthrodesis. We assessed SL angle and gap during testing to ensure there was no significant motion between the scaphoid and lunate, thus confirming stable simulated fusion. Differences in ROM were compared between baseline and simulated SL arthrodesis using paired t tests. RESULTS: Mean SL angle remained constant between pre- and post-arthrodesis imaging (47° ± 6° vs 46° ± 4°) and did not change during post-arthrodesis ROM testing, indicating a stable simulated fusion. Compared with baseline, SL arthrodesis had a statistically significant reduction in maximum flexion of 6° and 9° based on fluoroscopy and goniometry, respectively, in dart-thrower's extension of 5° and 9° based on fluoroscopy and goniometry, respectively, and in dart-thrower's flexion of 6° for both fluoroscopy and goniometry. No other ROMs after simulated SL arthrodesis were significantly different compared with baseline. CONCLUSIONS: The effects of simulated SL arthrodesis on radiocarpal and midcarpal motion compare favorably with motion after SL soft tissue repair and other reconstructive techniques that have been previously reported. The statistically significant decreases in wrist flexion and dart-thrower's extension-flexion after simulated SL arthrodesis are of questionable clinical importance. CLINICAL RELEVANCE: These results may support reconsidering SL arthrodesis as a viable treatment option for acute or chronic SL instability with regard to apparent minimal adverse effects on functional wrist ROM.

RESUMO

BACKGROUND: Symptomatic osteochondromas (OCEs) of the proximal humerus present a number of challenges, based upon their location and proximity to neurovascular structures. The purpose of this investigation was to evaluate the characteristics of these lesions and report the early results of surgical excision in children. METHODS: This is a retrospective case series of 31 pediatric patients with proximal humeral OCE treated with surgical excision. Radiographs and medical records were reviewed to evaluate tumor characteristics, treatment, and clinical results. The mean patient age was 13 (SD, 4) years, and the median follow-up was 11 months (range, 1 to 78 mo). RESULTS: From 1995 to 2009, 31 patients with proximal humeral OCE underwent surgical excision. Indications for surgery included pain in 25 (81%) and limited range of motion in 8 (26%). The OCE were most commonly posterolateral (23%) and posteromedial (16%). The site of OCE significantly influenced the extent of mass excision. OCEs located anteriorly, laterally, and posterolaterally had an average of 92% of mass excised (range, 69% to 100%), whereas those located posteromedially had an average of 68% of mass removed (range, 30% to 82%; P=0.02). Two patients (6%) had persistent postoperative pain, and 2 had recurrence. The deltopectoral approach was most commonly utilized (61%). For the posteromedial lesions, the direct medial approach led to more complete excision (79% vs. 51%). There were no neurovascular complications. CONCLUSIONS: Surgical excision of proximal humerus OCE led to favorable results, though persistent postoperative pain was seen with inadequate excision. Despite risks of neurovascular injury, a direct medial approach should be considered for posteromedial lesions. LEVEL OF EVIDENCE: Level IV-retrospective study.

RESUMO

BACKGROUND: The AAOS's Clinical Practice Guideline on "Optimizing Care of Rotator Cuff Problems" suggested a lack of high-quality data. Our purpose is to quantify the quality of randomized controlled trials of rotator cuff disorders via the Jadad score, and to apply the 2010 Consolidated Standards of Reporting Trials CONSORT Criteria to determine factors associated with high Jadad scores and areas for improvement. METHODS: A systematic review using PRISMA guidelines was performed. Utilizing an iterative search strategy of the top 6 impact factor orthopaedic journals from 2001 to 2011, all randomized controlled studies involving rotator cuff disorders were identified and scored in a systematic, blinded fashion. Each study received a Jadad score. Adherence to CONSORT criteria was quantified and linked to the Jadad score via linear regression. Common deficiencies were described. RESULTS: A total of 129 manuscripts were identified; 54 met inclusion criteria: total patients n = 4099; mean patients per article = 76; range, 16-660. The mean Jadad score was 3.0. Sixty-six percent (35/53) of studies were high quality (high quality: >3). Among these, the majority (63%, 22/35) were nonoperative trials. Adherence to CONSORT Criteria was associated with higher Jadad scores (R(2) = 0.3). The most common deficient CONSORT Criteria were: trial design descriptions (66%; 36/54 studies), descriptions of randomization type (65%; 35/54), and power analysis (46%; 25/54). CONCLUSION: The majority of randomized controlled trials of rotator cuff pathology are high-quality studies based on the Jadad score. Adherence to CONSORT criteria is linked to high-quality scores. Future studies should use full CONSORT Criteria.

RESUMO

The distal radioulnar joint (DRUJ) is a complex structure that contributes to full, painless forearm rotation and weight bearing. Stability requires adequate bony architecture and robust soft-tissue support. Arthritis of the DRUJ between the sigmoid notch of the distal radius and the ulnar head can be caused by traumatic, inflammatory, congenital, and degenerative processes. Initial management of symptomatic DRUJ arthritis is nonsurgical. Surgery is reserved for patients with refractory pain. Although outcomes typically are positive following excision of the distal ulna, serious potential postoperative complications include instability and potentially painful impingement of the residual distal ulnar stump. Procedures used to manage the unstable residual ulna include soft-tissue stabilization techniques and DRUJ implant arthroplasty.

RESUMO

STUDY DESIGN: Systematic literature review from 1970 to 2007. OBJECTIVE: This study reports the results of a systematic review comparing surgical decompression ± radiation to radiation therapy alone among patients with metastatic spinal cord compression. SUMMARY OF BACKGROUND DATA: Currently, the optimal treatment of metastatic spine lesions is not well defined and is inconsistent. Radiation and surgical excision are both accepted and effective. There appears to be a favorable trend for improved neurological outcome with surgical excision and stabilization as part of the management. METHODS: A review of the English literature from 1970 to 2007 was performed in the Medline database using general MeSH terms. Relevant outcome studies for the treatment of metastatic spinal cord compression were selected through criteria defined a priori. The primary outcome was ambulatory capacity. A random effects model was built to compare results between treatment groups, based on calculated proportions from each study. RESULTS: Of the 1595 articles screened, 33 studies (2495 patients) were selected based on our inclusion and exclusion criteria. Sixty-four percent of the patients who underwent surgical decompression, tumor excision, and stabilization had neurological improvement from nonambulatory to ambulatory status. Twenty-nine percent of the radiation therapy group regained the ability to ambulate after treatment (P < 0.001). Paraplegic patients had a 4-fold greater recovery rate to functional ambulation with surgical intervention than with radiation therapy alone (42% vs. 10%, P < 0.001). Pain relief was noted in 88% of the patients in the surgical studies and in 74% of the patients in studies of radiation therapy (P < 0.001). The overall surgical complication rate was 29%. CONCLUSION: This systematic review suggests that surgical excision of tumor and instrumented stabilization may improve clinical outcomes compared with radiation therapy alone, with regard to neurological function and pain. However, most data in the current literature are from observational studies, where variations in patient population and treatments cannot be controlled. This compromised our ability to compare the results of both treatments directly.

RESUMO

BACKGROUND: Osteochondral fractures of the talar dome (OCFT) are frequently associated with ankle fractures. Controversy exists regarding the treatment of acute Grade III and IV OCFT. Osteochondral autograft transplantation (OAT) is a possible operative solution. MATERIALS AND METHODS: We performed OAT in 16 patients with acute Grade III or IV OCFT. There were ten males and six females with the average age of 33.9 (range, 18 to 49) years. The average period of followup was 36.3 (range, 21 to 48) months. OCFT was identified, and clinically determined to be Grade III or IV using radiographs and intraoperative assessment. Seven patients were Grade III, nine patients were Grade IV OCFT. The OAT consisted of two sequential procedures: 1) harvesting of osteochondral autograft cylinder from the nonweightbearing surface of the ipsilateral knee, and 2) implanting the donor graft into the talar defect with press-fit technique. Single cylinder transplantation or a mosaicplasty was used. The outcome was determined by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, the simplified symptomatology evaluation, plain radiography and MRI. RESULTS: The mean size of the osteochonral fracture defects was 84.1 (range, 50 to 125) mm(2), and the mean depth was 2.5 (range, 1 to 5) mm. The mean AOFAS score was 95.4 (range, 86 to 100) points postoperatively. At the latest followup, there was no radiographic evidence of post-traumatic arthritis. Based on the MRI of all patients, 93.7% of the osteochondral grafts showed bony integration and articular congruity of the talar dome. CONCLUSION: OAT was shown to be an effective treatment with excellent clinical outcome and imaging evidence of graft integration.

RESUMO

Modifications in implant design and improvements in surgical technique have expanded the applications of total elbow arthroplasty. Complications associated with reconstructive elbow surgery persist, however, often leading to profound and sometimes nonsalvageable disability. The most recognized complications include implant loosening, periprosthetic fracture, implant failure, infection, triceps insufficiency, and nerve palsy. Although far fewer elbow arthroplasties than lower extremity arthroplasties are performed, the proportion of complications is greater with elbow arthroplasty, and the outcomes of secondary reconstruction are less favorable.

RESUMO

This case report identifies a traumatic laceration of the long head of the biceps brachii associated with a displaced surgical neck fracture of the humerus in a 37-year-old woman who sustained a fall while skiing. At the time of surgery, the tendon was found sharply divided and repaired primarily. The fracture was fixed with a proximal humeral blade plate. Followup revealed nearly full glenohumeral motion and a functional biceps muscle by 4 months.
