The use of Stack splint or aluminum finger splint in the conservative management of acute Doyle type IVb bony mallet finger.

BACKGROUND: The aim of this study was to compare the functional outcomes and direct costs of Stack splints and aluminum finger splints when used in the conservative management of patients with acute Doyle type IVb bony mallet finger. METHODS: We retrospectively analyzed demographic and clinical characteristics, functional outcomes (using the Crawford classification, DIP flexion angles, and extension lag measurements), time to confirmation of union, and splint costs of 24 patients treated with aluminum finger splints (Group 1) and 20 patients treated with Stack splints (Group 2). RESULTS: Of 44 patients, the median age was 38 (range, 20-59) years, 14 (32%) were smokers, 23 (52%) had fourth digit injuries, 32 (70%) had injuries to the dominant hand, 30 (68%) had a mechanism of injury of a fall, and median follow-up was 15 (range, 12-18) months; none of these differed significantly between Group 1 and Group 2 (all p > 0.05). In Group 1, functional outcomes were excellent and good in 14 (58%) and 10 (42%) patients, respectively; in Group 2 functional outcomes were excellent and good in 13 (62%) and 7 (35%) patients, respectively; and there was no significant difference between the groups. Median extension lag was 3.2° (range, 3.0°-3.5°) in group 1 and 3.4° (range, 3.2°-3.8°) in group 2, indicating no significant difference between groups. Complete union was confirmed radiographically in all patients. Per-patient cost was significantly lower for aluminum finger splints (0.208 TRY [US $0.03]) than for Stack splints (25 TRY [US $3.60]). CONCLUSIONS: Good functional outcomes are possible with the use of either Stack or aluminum finger splints in patients with acute Doyle type IVb mallet finger, confirming that conservative management may be appropriate for these injuries. Direct costs of Stack splints are many times greater than those of aluminum splints, though the costs for both are relatively low. LEVEL OF EVIDENCE: Therapeutic, Level III.

Comparison of plaster cast and open reduction internal fixation in delayed fourth and fifth carpometacarpal fracture-dislocations.

OBJECTIVES: This study aims to compare the clinical, radiological, and functional outcomes of the late-presenting ulnar carpometacarpal (CMC) joint injuries treated conservatively with plaster cast versus treated surgically with open reduction internal fixation (ORIF). PATIENTS AND METHODS: Between May 2019 - October 2021, a total of 28 patients (26 males, 2 females; mean age: 32.2±10.3 years; range, 20 to 59 years) who were treated conservatively or surgically were retrospectively analyzed. Fourteen patients operated with ORIF were included in the first group (surgery group), and 14 patients followed conservatively with a plaster cast were included in the second group (conservative group). The patients were classified according to Cain's classification and the AO Foundation and Orthopedic Trauma Association (AO/OTA) classification. The patients were evaluated in terms of pulp palm distance (PPD), Visual Analog Scale (VAS), Disabilities of the Arm, Shoulder and Hand (DASH) score, grip strength, time to return to work, follow-up time, and presence of complications. RESULTS: No significant difference was found in terms of the pain and functional scores. In the conservative group, the grip strength of the injured side was significantly lower than the healthy side (p=0.0093). The patients with and without metacarpal fracture subluxation/dislocation were evaluated separately, and the grip strength of the fractured side in the subluxation/dislocation group was found to be significantly higher in the surgery group than the conservative group (p=0.0237). In the group with subluxation/dislocation, the recovery time increased, as the time to treatment increased. In three patients in the conservative group, the PPD values were 2, 3, and 4 mm, respectively while it was 0 mm for all in the surgery group. CONCLUSION: The non-bridging dorsal buttress plate technique with or without a Kirschner wire is effective in patients with delayed ulnar CMC fracture-dislocations. Although surgery is associated with longer time to return to work, long-term results obtained with anatomical reduction of the joint are satisfactory for manual workers.

Nascent Malunion of Distal Radius Fractures Treated with Fixed Angled Volar Plates without Using Bone Grafts.

Purpose: Malunion of the distal radius is a common complication. Using bone grafts is common to restore the bone to an acceptable level. This study aimed to verify if it is necessary to use bone grafts in nascent malunion of distal radius fractures treated with fixed angled volar plates and which radiographic parameters are essential to obtain satisfactory outcomes. Methods: This single-centered prospective study included 11 patients who underwent corrective osteotomy of the radius for malunion. Patients with a metaphyseal, extraarticular osteotomy stabilized by a volar fixed angle plate within 3 months after the fracture are included. Patients underwent a standard radiological evaluation at postoperative 1 month, 3 months, 6 months, 1 year, and annually thereafter. Radial inclination, radial height, ulnar variance, and palmar tilt were measured. Wrist ranges of motion are measured throughout follow-up with a goniometer. Grip strength is measured using a Jamar Hand Dynamometer. The function is evaluated via the Gartland-Werley (GW) score and the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Results: The mean age of 11 patients, 9 (81.82%) males, included in the study was 41.45 ± 14.89 years. The mean post-fracture admission time is 39.3 ± 15.1 days. Radial inclination, radial length, and ulnar variance improved significantly after surgery (p = 0.0023, 0.0002, 0.0037). Radial inclination values are within normal limits for all patients at admission. The radial length was in the normal range for 72.73%, the ulnar variance was in the normal range for 72.73%, and palmar tilt was in the normal range for 100% of the patients. Extension 54.55%, flexion 72.73%, radial deviation 81.82%, ulnar deviation 63.64%, pronation 90.91%, and supination 72.73% were achieved after surgery. GW average was 3.09 ± 3.24 DASH score average was 12.24 ± 13.48. The mean grip strength was 29.27 ± 7.21 on the operated side, while it was 34.91 ± 5.32, on the healthy side, with a significant difference (p = 0.0108). Conclusion: It is possible to get good results without using bone grafts in corrective osteotomy of distal radius malunions.

The diagnostic value of ultrasonography and magnetic resonance imaging in missed hand tendon injuries.

BACKGROUND: Patients with hand tendon injuries may present to the hand surgery clinic in the late stage after being examined in emergency departments. Even if an approximate idea has been obtained in physical examination of these patients, diagnostic imaging is usually requested for reconstructive approach, correct planning of surgical incisions and medicolegal reasons. The primary purpose of this study was to determine the overall accuracy of Ultrasonography (USG) and Magnetic Resonance Imaging (MRI) in patients with late presentation of a tendon injury. METHODS: The surgical findings and imaging reports of 60 patients (32 females, 28 males) who underwent surgical exploration, late secondary tendon repair or reconstruction with a diagnosis of late-presenting tendon injury in our clinic were evaluated. Comparisons were made of 47 preoperative USG images (18-874 days) and 28 MRI (19-717 days) results for 39 extensor and 21 flexor tendon injuries. The imaging reports were interpreted as partial rupture, complete rupture, healed tendon and adhesion formation and these were compared with the surgical reports in terms of accuracy. RESULTS: In extensor tendon injuries, the sensitivity and accuracy values were both 84% for USG and 44% and 47% for MRI, respec-tively. In flexor tendon injuries, the sensitivity and accuracy values were 100% for MRI and 50% and 53%, respectively, for USG. Of the 4 sensory nerve injuries, 4 were missed on USG and 1 on MRI. The results obtained with USG and MRI in the late-presenting patients in this study were lower than those reported in previous USG and MRI studies in the literature. CONCLUSION: Scar formation with tendon healing causes a change in anatomy, which could prevent accurate evaluation. There-fore, it would be beneficial for surgeons to start evaluating their patients with easily accessible ultrasonography; thus, surgical morbid-ity should be reduced.

Malignant Tumors of the Foot and Ankle.

BACKGROUND: Surgical treatment is usually required for malignant foot and ankle tumors. In this study, we sought to review factors in treatment that may be associated with morbidity and mortality. METHODS: All malignant foot and ankle tumors at our institution between April 1988 and April 2018 were retrospectively reviewed. The surgical modalities used and clinical outcomes of patients according to the anatomic location (Kirby zone) and clinical stage (Enneking system) of each tumor were described. Extent of surgical resection required, recurrence, and death rates were assessed. RESULTS: Between April 1988 and April 2018, 80 patients with malignant tumors of the foot and ankle were treated at out institution. Mean age of patients was 42.6 (range, 3-89) years. Mean follow-up was 30.2 months (range, 24-120). Tumors were primary in 75 patients (94%) and metastatic from another organ in 5 patients (6%). Tumors originated from bone in 18 patients (22%) and from soft tissue in 63 patients (78%). Synovial sarcoma was the most common soft tissue tumor, and osteosarcoma was the most common osseous tumor.All patients had surgery to resect their tumor. Twenty-one (26%) had unplanned surgical procedures without initial biopsy at an outside institution prior to referral. Those patients were more likely to be treated with amputation or wide excison and free flap surgery (P < .01). The recurrence rate was 50% for the unplanned surgery group and 22% for the planned surgery group. Mortality rate was 10% for the unplanned group and 6% for the planned group. The recurrence and mortality rate was higher in the unplanned group (P = .03). CONCLUSION: Our study suggests that unplanned initial surgeries are associated with higher recurrence and mortality rates and reinforces the notion that these patients should be referred for treatment at a center with specialized expertise in tumor management. LEVEL OF EVIDENCE: Level, IV, retrospective case series.

Can headless screw used in fixation of the scaphoid proximal pole fracture be broken after wrist trauma? An unreported complication of scaphoid surgery.

The post-traumatic impairment of blood supply of the scaphoid bones' proximal pole is the subject of controversy in the surgical techniques which would heal this fracture. In a surgery performed with a dorsal approach, the main goal is to make a strong fixation with a small incision and a good implant without disturbing the blood supply of the bone. To date, complications related to surgical treatment of scaphoid proximal pole fractures have been reported in detail. However, there is no other study which presents headless screw failure which placed for the scaphoid proximal pole fracture surgery. Although implant technologies have been developed nowadays, our case report highlights that the endurance of these implants has not been carried out in such proximal pole fractures of the scaphoid, yet. Herein, we present the explanation of a broken headless screw which was placed into the proximal pole fracture of scaphoid, avoiding to affect bone stock of the scaphoid surgical technique. We believe that this surgical technique would be helpful to manage similar difficult situations for orthopedic surgeons.

The importance of Böhler's angle in calcaneus geometry: A finite element model study.

OBJECTIVES: Calcaneal fractures are the most common tarsal fractures following a foot-ankle trauma. The Böhler's angle is an important measurable angle before, during, and after surgery. In this study, we aimed to investigate correlation between Böhler's angle, calcaneal strength, and subtalar joint stress using a finite element analysis (FEA). PATIENTS AND METHODS: Between January 2016 and December 2016, computed tomography (CT) scans were used with MIMICS® software for FEA. The ankle and foot of a 23-year-old male person with a height of 180 cm and weighing 80 kg was modeled as reference. Raw coronal CT images were obtained in Digital Imaging and Communications in Medicine format with the resolution of 512X512 pixels and 0.3-mm slice intervals in 135 kV. The structures including tibia, fibula and 26 other bones (talus, calcaneus, cuboid, navicular, three cuneiforms, five metatarsals, and 14 components of phalanges), cartilage and ligamentous tissues were modeled to form ankle joint. After determining Böhler's angle as 35 degrees for the reference model, a fracture line was created on calcaneus. Calcaneus was remodeled with the Böhler's angle of 45, 40, 30, 25, 20, 10, and 0 degrees respectively. All models were transferred to ANSYS software for FEA and the loads on the lower extremities with normal posture were applied on models. RESULTS: Analysis of all models based in the reference model revealed that maximum tension values on calcaneus increased, while the Böhler's angle decreased, indicating a statistically significant difference. The decreased Böhler's angle indicated statistically significantly higher maximum tension values (p=0.04). Action force in subtalar joint was evaluated by comparing with the forces in reference model. The increased Böhler's angle was found to be associated with statistically significantly decreased amount of load on subtalar joint. The decreased Böhler's angle was related to the statistically significantly increased amount of load on subtalar joint. CONCLUSION: Our study results suggest that decreased Böhler's angle increases the possibility of subtalar arthrosis, although overcorrection of the Böhler's angle seems not to increase the risk of subtalar arthrosis.

A rare cause of osteomyelitis of distal phalanx: Candida lusitaniae.

Osteomyelitis of the phalanx caused by Candida species are rare. A 49-year-old female patient was admitted to an external center with a splinter injury of the third phalanx of the middle finger of her left hand about 45 days ago. She was referred to our clinic with persistent pain and discharge, despite four-week antibiotherapy. Debridement and curettage were performed and partial excision of the distal phalanx at an appropriate level was done. Her complaints gradually resolved postoperatively with prescribed antibiotics for the pathogen identified as Candida lusitaniae based on the intraoperative cultures. At her three-month follow-up visit, treatment yielded near-excellent results. To the best of our knowledge, this is the first case of osteomyelitis of the distal phalanx caused by Candida lusitaniae in the literature, highlighting the importance of definitive diagnosis and pathogen-specific treatment, rather than empirical treatment, to achieve favorable results with cure.

Spontaneous Bone Regeneration of Distal Half Ulnar Segment After Open Fracture of Forearm in a Pediatric Case.

Loss of the radius with open fractures of the forearm is rarely reported in pediatric cases and to the authors' knowledge, cases of segmental loss of the distal half of the ulna have not been previously reported. A 6-year-old girl was admitted with a Gustilo-Anderson type IIIB open forearm fracture and loss of the distal half of the ulna after a motor vehicle accident. Serial debridement was performed and a Kirschner wire was inserted into the distal half of the ulna. Unexpectedly, the ulna regenerated and the defect healed 4 weeks later. Soft tissue coverage was achieved with a skin graft and uneventful healing ensued. Eight weeks later, the bone was spontaneously and completely reconstituted. This case report demonstrates that substantial defects of the ulna may be spontaneously reconstituted over time.

Outcomes of primary surgical repair of zone 2 dDigital nerve injury.

The objective of our study was to assess the functional and sensory outcomes of the primary repair of 138 digital nerve injuries in 48 consecutive patients between January 2012 and November 2014, and to determine whether there were any relationships between demographics, clinical characteristics, or functional test results and post-operative sensory recovery outcomes. Mean follow-up was 14 (range, 10 to 20) months. Sensory evaluation was performed using the static two-point discrimination test, and post-operative sensoryrecovery results were classified according to the Seddon Classification: 69 (50%) injuries were S3+, 3 (2%) were S3, 15 (11%) were S2, 18 (13%) were S1, and 33 (24%) were S0. Sensory recovery was associated with time between surgery and testing and with objective functional recovery. More than half of digits sustaining nerve injuries had good intermediate-term recovery of sensation after early primary surgical repair. Surgeon experience and early primary repair may have a favorable impact on results.

Predictors of Lower Extremity Amputation and Reamputation Associated With the Diabetic Foot.

In the present study, we aimed to identify the comorbidities that would be predictive of requiring lower extremity amputation or reamputation for diabetic foot wounds. We performed a retrospective review of 132 consecutive patients who had undergone lower extremity amputations (110 patients) or reamputations (22 patients) for diabetic wounds from January 2013 to March 2016. We used multivariate logistic regression to calculate the odds ratios (ORs) for amputation and reamputation for various comorbidities. The ORs of undergoing amputation were greatest for adult males (OR 5.12, 95% confidence interval [CI] 1.56 to 13.04; p = .05) and those with longer term diabetes (OR 4.22, 95% CI 2.01 to 12.95; p = .05), wound infection (OR 3.94, 95% CI 1.04 to 9.00; p = .05), diabetic neuropathy (OR 3.53, 95% CI 1.07 to 9.11; p = .05), and a positive history of smoking (OR 3.04, 95% CI 1.55 to 9.89; p = .05). Similarly, the ORs of undergoing reamputation were greatest for adult males (OR 4.06, 95% CI 1.02 to 12.08; p = .05) and those with longer term diabetes (OR 3.67, 95% CI 1.94 to 11.42; p = .05), wound infection (OR 3.12; 95% CI 0.9 to 8.32; p = .05), diabetic neuropathy (OR 3.01, 95% CI 0.92 to 8.54; p = .05), and a positive history of smoking (OR 2.89, 95% CI 1.09 to 9.42; p = .05). The early identification of these comorbidities could help determine which patients are most likely to require amputation or reamputation.

Winograd Method Versus Winograd Method With Electrocoagulation in the Treatment of Ingrown Toenails.

An important component of the Winograd surgical method for an ingrown toenail is total excision of the associated germinal matrix. However, this might not always be accomplished with the procedure. We hypothesized that the surgical results might be improved by adding electrocoagulation of the germinal matrix to the Winograd method. The objective of the present study was to compare the recurrence, satisfaction, and complication rates of the Winograd method with those of the Winograd method with electrocoagulation. We retrospectively evaluated the records of 102 patients with single Heifetz stage 2 or 3 ingrown toenails who had undergone surgery from January 2013 to October 2014 using 1 of these 2 methods. Of the 102 patients, 50 (49%) underwent the Winograd method and 52 (51%) underwent the Winograd method with electrocoagulation. The mean follow-up period of our patients was 12 (range 6 to 22) months. An ingrown toenail recurred in 3 patients (6%) in the Winograd group and in no patient in the Winograd with electrocoagulation group (p = .04). Among the patients in the Winograd group, 46 (92.0%) were satisfied or very satisfied. Among the patients in the Winograd plus electrocoagulation group, 49 (94.2%) were satisfied or very satisfied (p = .04). No complications developed in either group. In conclusion, the Winograd method for ingrown toenails results in high satisfaction rates, low recurrence rates, and low complication rates. The addition of electrocoagulation of the germinal matrix to the Winograd method could result in even lower recurrence rates, while maintaining high patient satisfaction and without increasing the risk of complications.
