Recurrence Rates of Dorsal Wrist Ganglion Cysts After Arthroscopic Versus Open Surgical Excision: A Retrospective Comparison.

BACKGROUND: This study directly compares the recurrence rates of dorsal wrist ganglion cysts in patients treated via open surgical excision versus arthroscopic surgical excision. We hypothesized that there would be no difference between recurrence rates with these 2 surgical options. METHODS: We retrospectively reviewed the charts of all patients with a dorsal ganglion cyst undergoing either open or arthroscopic surgical excision at a single academic center with 3 fellowship-trained attending hand surgeons from 2012 to 2017. Charts were identified using Current Procedural Terminology codes and were reviewed using postoperative office notes for preoperative and postoperative symptoms, episodes of recurrence, time at which recurrence occurred, subsequent operations, and outcome at final follow-up. RESULTS: The charts of 172 patients undergoing either arthroscopic or open dorsal ganglion excision were reviewed. Nine of 54 (16.7%) arthroscopic excisions resulted in cyst recurrence, while 8 of 118 (6.8%) open excisions resulted in cyst recurrence (P = .044). Two of 9 (22%) recurrences after arthroscopic ganglion excision versus 2 of 8 (25%) recurrences after open ganglion excision underwent repeat surgical intervention. Time to recurrence, as well as final follow-up, was not statistically different between groups. CONCLUSIONS: Dorsal wrist ganglion cysts are the most common benign soft tissue mass of the upper extremity, but it remains unknown whether arthroscopic or open surgical excision leads to lower recurrence rate. Scant literature exists directly comparing these 2 methods of surgical excision. This study suggests that open excision of dorsal wrist ganglia leads to a lower recurrence rate than does arthroscopic excision.

An Analysis of Extensor Carpi Ulnaris Groove Morphology and Tendon Instability.

BACKGROUND: The extensor carpi ulnaris (ECU) tendon has a distinct subsheath at the distal ulna. Symptomatic tears of this subsheath and subluxation of the ECU tendon often require reconstruction. We sought to determine the anatomical constraints of the ECU subsheath. METHODS: The ECU subsheath was exposed on 12 fresh-frozen upper extremities. The tip of the ulnar styloid, the distal ulnar joint surface, and the proximal extent of the distal radio-ulnar joint were identified and dimensions measured. Subluxation of the tendon was then assessed with and without an intact subsheath in 9 specimens. The travel of the tendon was measured in pronation through supination and flexion before and after sectioning of the subsheath. RESULTS: The ECU subsheath is 8.9 mm (standard deviation [SD] = 0.8 mm) wide proximally and 9.0 mm (SD = 1.2 mm) distally. The distal ulnar insertion is 0.5 mm (SD = 0.8 mm) proximal to the tip of the styloid, and stretches 10.2 mm (SD = 2.7 mm) proximally. From maximum pronation to maximum supination and flexion, the ECU tendon traveled 3.32 mm (SD = 4.24) medially when the subsheath was intact and 5.42 mm (SD = 5.0 mm) after sectioning. The maximum depth of the ulnar groove was 2.5 mm (1.59-3.56 mm). There was no significant association between changes in ECU subluxation and the depth of the ECU groove (Spearman's rho = 0.25). CONCLUSION: The ECU subsheath is roughly 1 cm square stretching proximally from the ulnar styloid. ECU groove depth is not a significant independent predictor of tendon subluxation.

Flexor tenosynovectomy in carpal tunnel syndrome as a screening tool for early diagnosis of amyloidosis.

INTRODUCTION: Amyloidosis is a heterogeneous group of diseases that most often presents with advanced cardiac pathology. Another presentation of the disease can include symptoms consistent with carpal tunnel syndrome; however, the true incidence of amyloidosis in patients with carpal tunnel syndrome remains unclear. METHODS: We performed a retrospective chart review on all patients who underwent an open carpal tunnel release, with tenosynovium biopsy by a single surgeon between 01/2000 and 12/2018. Samples were stored in formalin following hematoxylin-eosin or congo red staining. A total of 199 patients were excluded for incomplete records, and carpal tunnel release performed for traumatic or infectious etiologies. Histologic findings of the attending pathologist were examined and categorized as follows: amyloidosis, fibrous tissue, tenosynovitis/inflammation edematous, benign tenosynovium, and gout. RESULTS: Exactly 898 open carpal tunnel releases were performed, and 699 patients were included for final analysis. In all patients, biopsies for histology with hematoxylin-eosin (HE) staining were taken; in those HE stains where amylogenic proteins were suspected (73 or 10.4%), a subsequent congo red staining was additionally performed which confirmed the diagnosis of amyloidosis in 10 patients (1.4% of the carpal tunnel procedures). Overall, 10 patients were identified and constituted 1.4% of all HE stains (n = 10/699) and 13.7% of all congo red stains (n = 10/73). CONCLUSION: Our results suggest that the incidence of amyloidosis in the general CTS patient population may be as high as 1.4% with routine screening by synovial biopsy and the diagnosis should be considered as a potential cause. Level of Evidence: III, retrospective study.

International Orthopaedic Volunteer Opportunities in Low and Middle-Income Countries.

ABSTRACT: Globally, the burden of musculoskeletal conditions continues to rise, disproportionately affecting low and middle-income countries (LMICs). The ability to meet these orthopaedic surgical care demands remains a challenge. To help address these issues, many orthopaedic surgeons seek opportunities to provide humanitarian assistance to the populations in need. While many global orthopaedic initiatives are well-intentioned and can offer short-term benefits to the local communities, it is essential to emphasize training and the integration of local surgeon-leaders. The commitment to developing educational and investigative capacity, as well as fostering sustainable, mutually beneficial partnerships in low-resource settings, is critical. To this end, global health organizations, such as the Consortium of Orthopaedic Academic Traumatologists (COACT), work to promote and ensure the lasting sustainability of musculoskeletal trauma care worldwide. This article describes global orthopaedic efforts that can effectively address musculoskeletal care through an examination of 5 domains: clinical care, clinical research, surgical education, disaster response, and advocacy.

The history of orthopaedic surgery in India: from antiquity to present.

Indian orthopedists have a legacy dating back more than 4000 years. Starting with the Harappan civilization, ancient orthopaedic surgeons reduced fractures and conducted therapeutic trepanations. Since then, Indian physicians have pioneered many of the orthopaedic techniques still used today - including the use of prosthetics, fracture tables, and rehabilitative physical therapy. Today, orthopaedic surgeons coexist with traditional Indian bonesetters. Although bonesetting practices can have complication rates as high as 40%, bonesetters still handle a majority of fractures in India and are often culturally preferred. Importantly though, bonesetters are often the only expedient option available in both rural and urban settings.

Debate Update: Surgery After 48 Hours of Admission for Geriatric Hip Fracture Patients Is Associated With Increase in Mortality and Complication Rate: A Study of 27,058 Patients Using the National Trauma Data Bank.

OBJECTIVE: To determine the association between surgical timing and short-term morbidity and mortality in elderly patients who sustain hip fractures using a national trauma database (OTA/AO 31A1-3, 31B1-3). DESIGN: Retrospective cohort study. SETTING: Level I-IV trauma centers in the United States. PATIENTS/PARTICIPANTS: All patients ≥65 years of age who underwent surgery for hip fracture from 2011 to 2013. INTERVENTION: Time to surgery of <24, 24-48, and >48 hours from admission. MAIN OUTCOME MEASUREMENTS: Primary outcome was mortality by hospital discharge. Secondary outcomes were complications of myocardial infarction, cardiac arrest, acute respiratory distress syndrome (ARDS), unplanned reintubation, pneumonia, stroke, severe sepsis, and intensive care unit length of stay. RESULTS: Twenty-seven thousand fifty-eight patients were included in the study. Relative to the <24 hours cohort, patients in the >48 hours cohort were at increased risk for mortality (OR 1.89, 95% CI 1.52-2.33, P < 0.001), ARDS (OR 2.57, 95% CI 1.94-3.39, P < 0.001 for ARDS), myocardial infarction (OR 2.19, 95% CI 1.64-2.94, P < 0.0001), pneumonia (OR 2.04, 95% CI 1.71-2.44, P < 0.001), severe sepsis (OR 2.34, 95% CI 1.52-3.58, P = 0.003), and intensive care unit stay (OR 2.48, 95% CI 2.25-2.74, P < 0.0001). A subgroup analysis showed that healthier patients (modified Charlson Comorbidity Index less than 5) who had surgery >48 hours were not at increased risk of mortality. CONCLUSIONS: For elderly patients with hip fractures, delaying surgery for more than 48 hours may be associated with increased short-term morbidity and mortality. This association may be pronounced for patients with more medical comorbidities. LEVEL OF EVIDENCE: Therapeutic Level III.

Prospective Analysis of Hand Infection Rates in Elective Soft Tissue Procedures of the Hand: The Role of Preoperative Antibiotics.

Background: The purpose of this study was to evaluate the efficacy of prophylactic antimicrobial prophylaxis in elective hand surgery in preventing postoperative infection. Methods: Between 2009 and 2012, we performed a multicenter trial in which patients undergoing elective hand surgeries were categorized into an antibiotic or control group depending on the center they were enrolled in. Surgical site infections were defined according to the Centers for Diseases Control and Prevention. Results: In total, 434 patients were included: 257 did not receive antibiotics (control) and 177 received antibiotics at a mean age of 61.0 years. In the control group, comorbidities were more common with 23.7% (61/257) in comparison to the antibiotics group with 14.1% (25/177). Only one surgical site infection in each group was identified. One wound was opened surgically, and an antimicrobial treatment was indicated in both cases. In addition, we observed four complications in the control group and three complications in the antibiotics group which required conservative management. No significant differences in the two cohorts in infection rate (0.006% vs 0.003%, χ2 = 0.07, P > .05) and complication rate (2.8% vs 1.6%, χ2 = 0.01, P > .05) were found. Conclusions: Our prospective multicenter trial showed no significant difference in infection rate in elective hand surgery whether antibiotics were administered preoperatively or not.

Treatment of nonunions of the humeral shaft with nonvascularized fibular strut allograft: postoperative outcomes and review of a surgical technique.

HYPOTHESIS: Persistent humeral shaft nonunions result in continued pain and disability of the affected arm and are difficult to treat even with several surgical procedures and locked plating. A fibular allograft provides bony purchase for fixation as well as rotational stability and bridging of nonunion defects. METHODS: We conducted a retrospective review of a single surgeon's clinical practice between July 1995 and January 2011. The inclusion criteria were patients aged ≥ 18 years who underwent revision surgery for a humeral shaft nonunion by open reduction and revision internal fixation with a supplementary fibular strut allograft. RESULTS: Thirteen patients who met the inclusion criteria were evaluated with physical examinations, validated functional outcome measures, and radiographs to assess union rates. The mean follow-up period was 7.5 years (range, 0.5-15.6 years); there were 11 women (85%) and 2 men (15%). Of the patients, 3 (23%) had proximal-third nonunions, 7 (54%) had middle-third nonunions, and 3 (23%) had distal-third nonunions. After revision surgery with fibular allograft, 10 of 13 patients went on to achieve healing, giving a union rate of 76.9%. The mean postoperative Disabilities of the Arm, Shoulder and Hand score was 38.1 points (standard deviation [SD], 27.6 points). The mean Constant score was 55.2 points (SD, 24.0 points), representing a 62% return of function compared with the contralateral side. The mean postoperative American Shoulder and Elbow Surgeons score was 65.4 points (SD, 28.5 points), and the average visual analog scale pain score (out of 10) was 2.1 (SD, 3.3) at final follow-up. CONCLUSION: Fibular allograft is an effective and straightforward option for treating humeral midshaft and distal-shaft nonunions; however, treatment of proximal-third nonunions remains challenging.

Estimates of Direct and Indirect Costs of Ankle Fractures: A Prospective Analysis.

BACKGROUND: The quantification of the costs of ankle fractures and their associated treatments has garnered increased attention in orthopaedics through cost-effectiveness analysis. The purpose of this study was to prospectively assess the direct and indirect costs of ankle fractures in operatively and nonoperatively treated patients. METHODS: A prospective, observational, single-center study was performed. Adult patients presenting for an initial consult for an ankle fracture were enrolled and were followed until recurring indirect costs amounted to zero. Patients completed a cost form at every visit that assessed time away from work and the money spent in the last week on transportation, household chores, and self-care due to an ankle fracture. Direct cost data were obtained directly from the hospital billing department. RESULTS: Sixty patients were included in this study. With regard to patient characteristics, the mean patient age was 46.5 years, 55% of patients were female, 10% of patients had diabetes, and 17% of patients were active smokers. Weber A fractures composed 12% of fractures, Weber B fractures composed 72% of fractures, and Weber C fractures composed 18% of fractures. Operatively treated patients (n = 37) had significantly higher total costs and direct costs compared with nonoperatively treated patients (p < 0.01). In all patients, losses from missed work accounted for the largest portion of total and indirect costs, with a mean percentage of 35.8% of the total cost. The mean period preceding return to work of the 39 employed patients was 11.2 weeks. Longer periods of return to work were significantly associated with surgical fixation and having less than a college-level education (p < 0.05). The mean time for recurring observed costs to cease was 19.1 weeks. CONCLUSIONS: In patients treated operatively and nonoperatively, the largest discrete cost component was a specific indirect cost. Indirect costs accounted for a mean of 41.3% of the total cost. Although the majority of the direct costs of ankle fractures are accrued in the period immediately following the injury, indirect cost components will regularly be incurred for nearly 5 months and often longer. To capture the full economic impact of these injuries, future research should include detailed reporting on an intervention's impact on the indirect costs of ankle fractures.

Thumb Disability Examination (TDX) as a New Reliable Tool for Basal Joint Arthritis.

Background The general assessment of basal joint arthritis (BJA) is limited using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. This has been shown to be insensitive to pain and disability levels, leading to the development and validation of the thumb disability examination (TDX) as a specific tool for BJA in 2014. Objective The goal of this study was to evaluate the reliability, sensitivity, and specificity of the TDX score for BJA. Methods A multicenter BJA database was established in 2007 to collect prospective data. We evaluated the correlation between the TDX score, visual analog pain scale with activity (A-VAS), Eaton-Littler score, and grip strength using a Pearson test. Additionally, we evaluated the pre- and postintervention scores to assess their predictive values. Results A total of 109 thumbs of 74 patients with TDX scores were evaluated. Females were more commonly affected (75.2%), and the mean age was 65.39 years (standard deviation: 10.04). The majority of participants were white (90.8%). A high correlation between TDX and A-VAS score (Pearson's correlation = 0.520; p < 0.001) and between grip strength (Pearson's correlation = -0.336; p < 0.005) and Eaton-Littler score (Pearson's correlation = 0.353' p < 0.01) was identified. Additionally, when comparing pre- and post-intervention for all treatment groups and for operative intervention, significant differences in TDX scores were observed (both p ≤ 0.01). No significant differences could be identified for DASH score or A-VAS when assessing these same groups. Conclusion The TDX score correlates to high Pearson's correlation values and p -values, especially in grip strength, Eaton-Littler score, A-VAS score, and pre-/postintervention for all treatment groups combined and when specifically assessing the surgical intervention group. As a result, it can be concluded that the TDX score is a specific tool for the assessment of BJA. Level of Evidence This is a Level II, prospective comparative study.

Treatment methods for post-traumatic elbow stiffness caused by heterotopic ossification.

HYPOTHESIS: Heterotopic ossification (HO) is a common complication of surgically treated elbow fractures that can inhibit range of motion and impair quality of life. Although there are many treatment methods for HO, there is a lack of consensus as to the best option. We hypothesized that contracture release combined with Botox injection would lead to improved functional outcome scores when compared with current treatment methods. METHODS: A retrospective review was conducted of patients who presented to a single surgeon with HO secondary to elbow fracture between 2005 and 2018. A total of 59 patients were identified who met inclusion criteria. Data were classified into 3 groups: contracture release (control - CR), Botox injection with CR (Botox + CR), and radiation therapy with CR (CR + RT). Range of motion measurements were obtained, including flexion, extension, pronation, and supination. RESULTS: A total of 30 patients (30 of 59, 50.8%) received CR, 6 (6 of 59, 9.2%) were treated with CR + RT, and 23 (23 of 59, 40.0%) had CR + Botox. There was a significant difference between pre- and postoperative arc of motion for both CR + RT (P < .01) and CR + Botox (P < .01). In addition, there was a significant difference in pre- and postoperative extension for patients who received intraoperative Botox injections (P < .05). There was no significant difference between pre- and postoperative motion nor extension in the CR group. CONCLUSION: Intraoperative Botox injection with CR is an effective method in the treatment of post-traumatic elbow stiffness caused by HO.

Comparison of Exposure in the Kaplan Versus the Kocher Approach in the Treatment of Radial Head Fractures.

BACKGROUND: The aim of this study was to compare the complete visible surface area of the radial head, neck, and coronoid in the Kaplan and Kocher approaches to the lateral elbow. The hypothesis was that the Kaplan approach would afford greater visibility due to the differential anatomy of the intermuscular planes. METHODS: Ten cadavers were dissected with the Kaplan and Kocher approaches, and the visible surface area was measured in situ using a 3-dimensional digitizer. Six measurements were taken for each approach by 2 surgeons, and the mean of these measurements were analyzed. RESULTS: The mean surface area visible with the lateral collateral ligament (LCL) preserved in the Kaplan approach was 616.6 mm2 in comparison with the surface area of 136.2 mm2 visible in the Kocher approach when the LCL was preserved. Using a 2-way analysis of variance, the difference between these 2 approaches was statistically significant. When the LCL complex was incised in the Kocher approach, the average visible surface area of the Kocher approach was 456.1 mm2 and was statistically less than the Kaplan approach. The average surface area of the coronoid visible using a proximally extended Kaplan approach was 197.8 mm2. CONCLUSIONS: The Kaplan approach affords significantly greater visible surface area of the proximal radius than the Kocher approach.

Radiographic Results of Unicortical Medial Malleolar Fracture Fixation.

BACKGROUND:: Medial malleolar fractures commonly occur as part of rotational ankle fractures, which often require surgery. Different fixation techniques exist, including unicortical or bicortical lag-screw fixation. Bicortical screws that engage the lateral distal tibia have been noted to be biomechanically superior to unicortical ones with a lower failure rate. The authors of this study have used unicortical screws routinely. This study was initiated to investigate the clinical results of a large series of patients with unicortical medial malleolar fixation. METHODS:: Patients who underwent unicortical medial malleolar fracture fixation between 2011 and 2017 were reviewed. In total, 461 ankle fractures were identified with a mean follow-up of 11.4 months (range, 3-57), of which 211 had a medial malleolar fracture. Eight patients were excluded as they did not follow up with the treating surgeons after surgery, leaving 203 patients for evaluation. The primary outcome was radiographic union. Any loss of reduction, complication, or subsequent surgery was recorded. Malunion was defined as greater than 2 mm displacement. RESULTS:: There were 2 asymptomatic nonunions (1.0%), 1 delayed union that healed using an external bone growth stimulator (0.5%), and 2 malunions of the medial malleolus (1.0%) with 1 asymptomatic. The other patient developed posttraumatic osteoarthritis but has not yet required further surgery. None of these 5 patients required revision medial malleolar surgery. Ultimately, the union rate using unicortical medial malleolar fixation was 99.0% (201/203). CONCLUSION:: Unicortical fixation of medial malleolar fractures resulted in consistently good healing. Even though biomechanical studies have shown that bicortical screws provide stronger fixation, our clinical results indicate that the need for this stronger fixation may be questionable. LEVEL OF EVIDENCE:: Level IV, retrospective case series.

The Optimal Suture Placement and Bone Tunnels for TFCC Repair: A Cadaveric Study.

Background Transosseous repair of foveal detachment of the triangular fibrocartilage complex (TFCC) is effective for distal radioulnar joint stabilization. However, studies of the optimal foveal and TFCC suture positions are scant. Purpose The purpose of this study was to clarify the optimal TFCC suture position and bone tunnels for transosseous foveal repair. Materials and Methods Seven cadavers were utilized. The TFCC was incised at the foveal insertion and sutured at six locations (TFCCs 1-6) using inelastic sutures. Six osseous tunnels were created in the fovea (foveae 1-6). Fovea 2 is located at the center of the circle formed by the ulnar head overlooking the distal end of the ulna (theoretical center of rotation); fovea 5 is located 2 mm ulnar to fovea 2. TFCC 5 is at the ulnar apex of the TFCC disc; TFCC 4 is 2 mm dorsal to TFCC 5. TFCC 1 to 6 sutures were then placed through each of the six osseous tunnels, resulting in 36 combinations, which were individually tested. The forearm was placed in five positions between supination and pronation, and the degree of suture displacement was measured. The position with the least displacement indicated the isometric point of the TFCC and fovea. Results The mean distance of suture displacement was 2.4 ± 1.6 mm. Fovea 2, combined with any TFCC location, (0.7 ± 0.6 mm) and fovea group 5, combined with TFCC 4 location (0.8 ± 0.8) or with TFCC 5 location (0.9 ± 0.6) had statistically shorter suture displacements than any other fovea groups. Conclusion For TFCC transosseous repair, osseous tunnel position was more important than TFCC suture location.

Association Between Radiological and Patient-Reported Outcome in Adults With a Displaced Distal Radius Fracture: A Systematic Review and Meta-Analysis.

PURPOSE: To evaluate the association between alignment, as determined by plain radiographs, and patient-reported outcome in adults with a displaced distal radius fracture. We also determined which specific radiological parameters are associated with patient-reported outcomes. METHODS: We performed a systematic literature search to identify studies that evaluated the association between radiological and patient-reported outcome in adults with a displaced distal radius fracture and who had an average follow-up of at least 12 months. Radiological outcome was determined as acceptable or unacceptable reduction, defined by radiological parameters. Patient-reported outcome was assessed with the Disability of the Arm, Shoulder, and Hand, the Quick-Disability of the Arm, Shoulder, and Hand, and the Patient-Rated Wrist Evaluation questionnaires. RESULTS: Sixteen articles were included, comprising 1,961 patients with a distal radius fracture. A significant mean difference of 4.15 points in patient-reported outcomes (95% confidence interval [CI], 0.26-8.04) was found in favor of an acceptable radiological reduction. Moreover, a significant mean difference of 5.38 points in patient-reported outcomes (95% CI, 1.69-9.07) was found in favor of an acceptable dorsal angulation, and 6.72 points (95% CI, 2.16-11.29) in favor of an acceptable ulnar variance. CONCLUSIONS: An unacceptable radiological reduction is significantly associated with worse patient-reported outcomes in adults with a displaced distal radius fracture. Dorsal angulation and ulnar variance are the most important radiological parameters. Despite the statistical significance, the mean difference of each association did not meet the threshold of the minimally clinically important difference and therefore were unlikely to be clinically important. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Arthroscopic Wrist Debridement and Radial Styloidectomy for Advanced Scapholunate Advanced Collapse Wrist: Long-term Follow-up.

BACKGROUND: Symptomatic stage 2 or 3 scapholunate advanced collapse (SLAC) wrist is aggressively treated with salvage procedures, such as proximal row carpectomy or partial wrist fusion with resultant pain relief but limited motion. We hypothesize that arthroscopic synovectomy, radial styloidectomy, and neurectomy will preserve wrist motion, relieve pain, and delay or avoid salvage procedures. METHODS: We evaluated outcomes in 13 wrists through questionnaires and 11 of these through additional physical examination at a mean follow-up of 5.0 years. Eight wrists were stage 2 and 5 were stage 3. Data at final follow-up included mobility/strength measurements, subjective outcome scores (Disabilities of the Arm, Shoulder, and Hand [DASH] and visual analog scale [VAS] pain), patient satisfaction, and return to work statistics. RESULTS: Patients had an average flexion-extension arc of 88.0° in the treated wrist and an average grip strength that was 95.0% of the contralateral side. No patients required revision surgery at follow-up. The 13 wrists reported an average DASH score of 16.4 and mean VAS pain score at rest and with activity of 17.9 and 31.6, respectively. All patients working prior to the procedure (n = 8) were able to immediately return to work. In all, 84.6% of patients were satisfied. CONCLUSIONS: The procedure studied may have advantages in relieving pain, while preserving wrist motion for SLAC stage 2 or 3 disease. This procedure does not preclude future salvage procedures in those patients with severe disease who prefer to maintain wrist motion for the short term. Patients experience good functional outcomes with the majority experiencing a reduction in pain with the ability to return to work.

Development and Validation of a Disease-Specific Questionnaire for Basal Joint Arthritis.

Background The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire is the most commonly used instrument to assess outcomes of basal joint arthritis (BJA). However, the DASH is subject to influence by the entire upper extremity. Purpose This study aims to develop and validate a disease-specific questionnaire for BJA that would be more sensitive to changes in thumb function and pain, and correlate better with objective and subjective metrics. Patients and Methods The thumb disability examination (TDX) was developed and 80 patients presenting with BJA at one of the two hospital-based hand clinics were enrolled in the validation study. At enrollment, subjects were given the TDX, DASH, and visual analog pain scale with activity (A-VAS) surveys. The strength was assessed. Patients receiving corticosteroid injection were seen for follow-up at 6 weeks and those who underwent surgery were seen between 3 and 6 months postoperatively. Both the groups were given the TDX, DASH, and A-VAS scales at follow-up. Results In total, 65 subjects were included in the analysis. Average TDX completion time was 134.3 seconds. The TDX correlated more strongly with A-VAS scores at baseline than the DASH, but less strongly with tip-pinch measures. The TDX was more responsive to injection and surgical treatments for BJA than the DASH, yielding a larger effect size and standardized response mean, and was the only instrument to significantly correlate with changes in A-VAS. Conclusion The TDX is a reliable instrument for assessing BJA treatment outcomes. It bears less of a burden on patients, is more responsive to symptomatic changes, and correlates better with most objective and subjective measures than the DASH. Level of Evidence II, diagnostic.

How Should the Treatment Costs of Distal Radius Fractures Be Measured?

Distal radius fractures (DRFs) are common, but the best way to measure the total cost of treating these injuries is not known. We conducted a study to measure the total treatment cost of DRFs to identify which items should be measured, and for how long, to capture all major cost-drivers. Eighty-two patients with DRFs were included in this prospective, observational study. All costs, both direct and indirect, were measured. Direct costs were measured for each patient from internal billing records. Indirect costs were obtained with a customized questionnaire. The major contributors to overall cost were physician fees, operating room costs, occupational therapy, and missed work, which together accounted for 92% of total cost. Recurring indirect costs largely resolved within 3 months for nonoperative management and within 6 months for operative management. Physician fees, operating room costs, occupational therapy, and missed work are the major cost-drivers for DRFs and should be measured for at least 6 months after injury. Indirect costs, particularly those associated with missed work, represent a significant amount of the total overall cost.

Augmentation of Fracture Healing Using Soft Callus.

OBJECTIVES: This study sought to investigate the effect of soft callus removal and reapplication in a rat closed femur fracture model. We hypothesized that removing soft callus will impair fracture healing, whereas reapplication will facilitate healing. METHODS: A closed midshaft femur fracture was created in 78 rats and stabilized with an intramedullary wire. Seven days later, rats were equally divided and fractures surgically exposed. In the control group, no callus was removed, whereas in the callus removal group CR(-) group, the callus was removed and in the callus replaced group CR(+), callus was removed and replaced. Half of the rats were killed at 4 and 7 weeks. Fracture healing was graded with radiographs and callus volume measured with micro-CT. Mechanical torsion properties were measured, and histologic analysis was conducted. RESULTS: At both end points, evidence of delayed healing was found on radiographs and micro-CT in CR(-) rats (P = 0.0001), whereas CR(+) rats showed normal fracture healing compared with controls. The normalized callus volume was similar in all groups at both end points. At 7 weeks, the maximum stiffness in CR(-) rats was 68% less than control (P = 0.0001). Stiffness increased 55% in CR(+) rats from CR(-) rats (P = 0.0017). Histology supported our findings with complete endochondral ossification in CR(+) rats but wide areas of hyaline cartilage in CR(-) rats at 7 weeks. CONCLUSIONS: Removal of soft callus in a rat model delays fracture healing at early and late time points, whereas replacement mitigates these negative consequences. Replacing the soft callus should be considered in all osteosynthesis procedures.

Technique Using Isoelastic Tension Band for Treatment of Olecranon Fractures.

The isoelastic ultrahigh-molecular-weight polyethylene tension band may be considered an alternative to stainless steel wire for tension band fixation of olecranon fractures. In this article, we present our technique using this isoelastic tension band and describe the outcomes of 7 patients who underwent open reduction and internal fixation of closed, displaced olecranon fractures with minimal or no articular surface comminution. We reviewed medical records and performed physical examinations and functional assessments. Anatomical reduction was maintained in all elbows through union. Physical examination measurements indicated nominal side-to-side differences in motion and strength. Mean Broberg and Morrey elbow score was good (92/100), and mean (SD) Disabilities of the Arm, Shoulder, and Hand score was 12.6 (17.2). One patient had a minor degree of hardware irritation at longest follow-up but did not request hardware removal. One patient underwent implant removal for a symptomatic implant 5 years after surgery. This easily reproducible technique yields excellent physical and functional outcomes.
