Neglected Bicondylar Fracture of the Distal Humerus Treated With Total Elbow Arthroplasty.

A 69-year-old woman suffered a distal humerus fracture including the medial and lateral condyles. She received conservative treatment with a posterior arm splint at a local healthcare center where she was evaluated by a non-specialist physician. Eight months later, she presented to our department complaining about severe instability. An upper limb specialist examined the patient at the time, and after thoroughly explaining the condition, he suggested a surgical approach with total elbow arthroplasty (TEA), which was then performed. At the one-year follow-up, the patient had a full range of motion without any complications or pain complaints. TEA in neglected fractures of the distal humerus is a poorly researched topic in the field of upper limb surgery with only scarce literature available. In this case report, we present the excellent outcomes of the procedure performed on an elderly patient after non-union regaining her quality of life and suggest that TEA can be a viable solution in elderly patients with complicated or non-united elbow fractures.

The 100 Top-Cited Articles on Medial Patellofemoral Ligament: A Bibliometric Analysis and Review.

Background: The medial patellofemoral ligament (MPFL) has been investigated widely in the past 30 years, resulting in many research achievements in this field. Purpose: To perform a comprehensive bibliometric analysis to evaluate the 100 top-cited articles on the MPFL. Study Design: Cross-sectional study. Methods: We searched the Scopus database in December 2022 using the terms "medial patellofemoral ligament" OR "MPFL." The search was confined to English-language articles, including technical notes, systematic reviews on clinical outcomes and/or complications, clinical studies, studies regarding complications, and basic science articles (either cadaveric or biomechanical); we excluded letters, case reports, personal opinions, guidelines, editorials, and narrative or other types of reviews. Analysis of the 100 top-cited articles was performed according to total number of citations, average citations per year (ACY), study type, country of origin, journal of publication, affiliated institution, and most published authors. Results: The total number of citations was 16,358 (range of citations per article, 72-692). The majority of articles were published as clinical studies (54%), with cadaveric studies being the second most common (21%). Most studies originated in the United States (32%), with Japan (15%) and Germany (13%) following. The American Journal of Sports Medicine published the majority of the 100 top-cited articles (37/100; 6304 citations) as well as the 10 top-cited articles according to ACY (7/10; mean, 285.14 citations). The most prolific authors were Nomura (8 articles); Burks (6 articles); and Inoue, Sillanpää, and Dreyhaupt (5 articles each). Conclusion: By analyzing the characteristics of the 100 top-cited articles, this study demonstrated that the MPFL is a growing and popular area of research, with the focus varying through timeline trends. Questions regarding MPFL anatomy, isometry, and biomechanics might have been answered adequately, but research regarding optimal fixation technique under various circumstances is still ongoing.

Capitate Proximal Fragment Migration Compressing the Median Nerve in Scaphocapitate Fracture: A Case Report.

BACKGROUND Scaphocapitate syndrome is a rare clinical entity consisting of a combined scaphoid and capitate fracture along with a 90- or 180-degrees rotation of the proximal capitate fragment. The syndrome is scarcely described in the literature, with proximal migration of the capitate fragment being reported only by Mudgal et al in 1995. Concurrent compression of the median nerve is a highly unfortunate event, suggesting a unique case presented here. CASE REPORT We present a unique case of scaphocapitate fracture-dislocation in a 25-year-old man with volar dislocation of the capitate's fragment deep to the median nerve. X-rays and CT scan were performed and the patient was treated few hours after the injury by a hand specialist, in order to prevent median neuropathy and avascular necrosis of the fragment. Open reduction and internal fixation utilizing a Herbert screw for the scaphoid fracture and 3 additional K-wires was performed. Immediately post-operatively, the acute neurological symptoms had subsided and good reduction was acquired radiologically. One year post-operatively the patient had regained good hand and wrist functionality, with no extension or flexion ROM deficits. CONCLUSIONS Immediate intervention in a specialized center with reduction and fixation utilizing a Herbert screw and K-wires showed favorable 1-year results in our case of scaphocapitate syndrome. The impending complications of median neuropathy and capitate avascular necrosis were avoided despite the high-risk injury pattern.

A Comprehensive Review of COVID-19-Infection- and Steroid-Treatment-Associated Bone Avascular Necrosis: A Multi-Study Analysis.

BACKGROUND: The COVID-19 pandemic has presented numerous challenges to the global healthcare system and emerging evidence suggests a potential link between COVID-19 treatment, specifically steroid therapy, and the development of avascular necrosis (AVN) of the hip. This review aims to provide a comprehensive overview of recent studies and case reports investigating the relationship between COVID-19, corticosteroid therapy, and the development of AVN. Understanding the nuances of AVN in the context of COVID-19 is crucial for healthcare professionals to navigate treatment decisions and mitigate potential complications. MATERIALS AND METHODS: The Preferred Reporting Items for Systematic Reviews and a Meta-Analysis (PRISMA) were used in the systematic review until 1 September 2023. The full texts of the remaining twenty-three (n = 23) articles were independently reviewed by the authors of this review. CONCLUSIONS: The association between steroid therapy for COVID-19 and the development of hip AVN is a noteworthy concern even though no relationship is evident between the duration of treatment, cumulative dosage of medication, maximum daily dosage received, and presence of AVN. Further research with larger cohorts and long-term follow up is needed to better understand the causative relationship and optimal management strategies for hip AVN in the context of COVID-19 and steroid therapy.

Post Traumatic Neuroma in Continuity of the Median Nerve in a Child: A Case Report.

An 8-year-old girl suffered a wrist laceration from a sharp glass, severing the median nerve. The nerve was end-to-end repaired at the time by a pediatric orthopedic surgeon. Six months later, the girl suffered wrist pain and hyperesthesia over the previous surgical incision, significantly affecting her daily activities. Physical examination revealed a palpable mass over the median nerve with a positive Tinel sign, and the diagnosis of a painful neuroma in continuity was set. She underwent another surgery where the defective neuroma in-continuity was excised, and the median nerve was reconstructed using sural nerve cable autografts. At 18 months follow-up after the second surgery, the girl appeared with a full passive and active painless range of motion and a negative Tinel sign. This is the first case of neuroma in continuity presenting in a child in the literature, successfully managed surgically.

Terrible Triad of the Shoulder: A Case Series and Literature Review.

INTRODUCTION: The shoulder terrible triad is an underdiagnosed injury pattern consisting of anterior shoulder dislocation, rotator cuff tear, and nerve injury from the brachial plexus in its original description. The purpose of this study is to raise awareness of the condition, suggest treatment strategies, and emphasize the difficulties in treating this condition. METHODS: This case series of seven patients from the same institution. All patients underwent x-rays before and after the reduction of the dislocation, MRI to assess the musculoskeletal injuries, and EMG and clinical examination to assess the nerve lesions. Early arthroscopic repair was opted for the rotator cuff tears. A conservative approach was chosen for the nerve lesions. Active forward flexion and external rotation, Constant score, and Visual to Analogue Scale (VAS) were recorded pre- and post-operatively. RESULTS: All the patients showed an improvement in function postoperatively. However, four of the seven patients did not recover fully. The mean Constant and VAS scores were improved from 15.2 +/- 2.8 (12 to 19) to 67 +/- 16.6 (44 to 86) and from 7.5 +/- 1 (6 to 9) to 2.3 +/- 0.8 (1 to 3), respectively. The patients were followed up for a mean time of 28.2 +/- 10.1 months (18 to 43 months). Time-to-surgery shorter than four weeks showed better results, but not statistically significant. CONCLUSIONS: The diagnosis of the shoulder terrible triad requires a high level of suspicion. Early arthroscopic repair for the rotator cuff tears and waiting for the nerve recovery is suggested. Delayed time from injury to surgery might be related to worse outcomes, but higher-level research is needed in this direction.

Osteoid Osteoma of the Trapezium: A Rare Case Report and Literature Review.

Osteoid osteoma is the most common benign osteogenic bone neoplasm. Osteoid osteomas are typically located in the metaphysis and diaphysis of long bones, especially the tibia and femur. However, less common sites of the skeleton can be affected as well, including carpal bones. Among carpal bones, the scaphoid and the capitate are the most affected. Osteoid osteoma of the trapezium is an extremely rare entity, with only seven cases reported in recent literature. We present a case of a 29-year-old male with persistent left wrist pain who was diagnosed with an osteoid osteoma of the trapezium bone. The diagnosis was based on the patient's history, clinical examination and findings from the CT scan, MRI, and plain radiographs. The patient was treated with an excision biopsy with no additional bone grafting. After a follow-up period of 12 months, no pain or signs of recurrence were present. We conducted a literature review to elucidate the clinical presentation as well as the proper diagnostic tools and therapeutic methods for this rare occurrence.

Surgical Treatment of a Neglected Thumb Volar Plate Injury in an 11-Year-Old Girl: A Case Report.

BACKGROUND Volar plate injuries are rare and difficult to diagnose and treat. Only a few cases have been described on the thumb, especially in children, that resulted in swan-neck type deformity. Conservative treatment has been suggested as first-line management, but surgical reconstruction utilizing flexor digitorum superficialis tenodesis has been described for refractive cases. Only a few attempted surgical repairs of the volar plate have been reported, since it is a technically demanding procedure. CASE REPORT We present the case of a neglected thumb volar plate injury in an 11-year-old girl after a thumb hyperextension injury. The patient presented 2 months after her injury with functional disability of her thumb. Magnetic resonance imaging had been performed, with no signs of volar plate injury, and she was consequently treated with an extension-blocking splint, with no effect. Clinical examination raised the suspicion of a thumb volar plate injury, which was confirmed during surgical exploration. Therefore, fixation with a bone anchor was performed, and the metacarpophalangeal joint was immobilized in 20° flexion with a percutaneously inserted Kirschner wire. After splinting for 3 weeks, the patient had 10 sessions of physical therapy. At 6-week follow-up, she presented with excellent active and passive range of motion and absence of pain. CONCLUSIONS Magnetic resonance imaging did not have high sensitivity. Six weeks after surgery, full range of motion was achieved, with no stiffness or tenderness at the first metacarpophalangeal joint, suggesting that a thumb volar plate injury had been managed surgically with a suture anchor with excellent results.

Functional performance of the upper limb and the most common boxing-related injuries in male boxers: a retrospective, observational, comparative study with non-boxing population.

BACKGROUND: To investigate the functional status and recording the most common injuries of the upper limb in male Greek boxing squad in comparison to the general population. METHODS: A retrospective injury surveillance study using an electronic questionnaire was performed in 2021. The questionnaire was sent to male members of the Greek Boxing Federation and consisted of three parts. Demographic data, functional status scales, training conditions, hours of training, the location and description of upper limb injuries and whether the injury occurred during competition or training and also whether it was a new or a recurrent one were gathered. The same questionnaire was sent to non-boxer males (military recruits), but without asking them to report any training parameters. Inclusion criteria were age < 35 years-old for all participants and no involvement in martial arts for the control group. Also, all participants (boxers and non-boxers) completed the Patient Rated Wrist Evaluation (PRWE) scale and the Quick Disabilities of Arm, Shoulder and Hand (quick-DASH) score. RESULTS: The final study cohort was consisted of 62 elite or amateur boxers and 75 non-boxer males, less than 35 years old. The quick-DASH score was found to be significantly lower (better) in boxers in comparison to the general population (15.65 ± 10.25 vs. 12.55 ± 8.62; p = 0.020) whereas the PRWE score was similar in both groups (9.25 ± 14.96 vs. 8.61 ± 13.05; p = 0.843). Physical therapy sessions, thumb injuries and boxer's knuckle were also found to be significantly higher in the boxers group. On the other hand, upper limb surgeries were significantly less in the boxers group. Finally, the size of boxing gloves was associated to the number of finger fractures, thumb injuries and ulnar sided wrist pain in boxers. CONCLUSIONS: Although a controversial sport, boxing appears to have no long-term consequences to the upper limb function, especially regarding hand performance. The size of gloves during heavy bag training was found to be an aggravating factor for hand injuries.

Isokinetic Muscle Strength and Knee Function in Anatomical Anterior Cruciate Ligament Reconstruction With Hamstring Autografts: A Prospective Randomized Comparative Study Between Suspensory and Expandable Femoral Fixation in Male Patients.

Background Clinical performance, anterior knee stability, and isokinetic strength after anterior cruciate ligament (ACL) reconstruction with hamstring autografts are mainly influenced by graft selection, femoral tunnel preparation, and type of femoral fixation. Expandable femoral fixation devices are expected to provide a stronger initial fixation with circular graft compression, a blind-ended tunnel in the femur with less enlargement, and a theoretical double-band ACL equivalent through graft rotation. This study aimed to evaluate isokinetic strength and functional capacity after ACL reconstruction with hamstring tendons using two different anatomical femoral fixation techniques (expandable vs fixed-looped button). Methodology A total of 48 male patients with ACL deficient knees were randomized to two different femoral fixation groups, namely, the expandable (AperFix) and the standard cortical (Button) group. The primary outcome measures were isokinetic hamstrings and quadriceps strength capabilities and the hamstrings/quadriceps ratio at 60 degrees/second (°/s) and 180°/s using a Cybex before and at three, six, nine, 12, and 24 months after surgery. Secondary measurements were anteroposterior knee stability at two years (using KT-1000 arthrometer) and the functional outcome using the International Knee Documentation Committee (IKDC 2000) form, the Tegner activity scale, and the Lysholm knee score. Data were compared using a paired t-test and analysis of variance, with a p < 0.05 level of significance. Results Most patients regained the 60°/s quadriceps strength between three and 12 months (62.5% for the Button group vs. 50% for the AperFix group), as well as the 180°/s strength (79.17% vs 70.83%); however, at the 24-month evaluation, seven (29.17%) patients in the Button group and five (20.83%) in the AperFix group had significant deficits. The 60°/s flexor strength was regained in the first six months in 19 (79.17%) patients in the Button group and in 16 (66.7%) patients in the AperFix group, whereas the percentages for the 180°/s strength were 79.17% and 75%, respectively. Beyond the 24-month evaluation, only three (12.5%) patients in the Button group and four (16.67%) in the AperFix group had significant flexor deficits. Regarding the H/Q ratio, at 60°/s, the mean recovery time was six and 7.5 months for the Button and AperFix groups, respectively, whereas 15 and 12 patients, respectively, did not recover during the two-year duration. At 180°/s, a mean recovery time of six months was needed for the button group, and nine patients did not recover two years later. For the AperFix group, nine months were needed, and 12 patients did not recover in two years. Clinical performance and anterior knee stability showed no statistically significant differences between groups. Conclusions Although there were no significant differences in clinical performance, knee stability, and isokinetic strength testing between expandable and cortical button femoral fixation groups, return to play was doubtful at two years postoperatively.

Elbow Dislocation With Associated Essex-Lopresti Injury: A Case Treated Conservatively.

A 23-year-old woman suffered a posterior elbow dislocation, distal radius intraarticular fracture, distal radioulnar joint subluxation, and coronoid process fracture, suggesting an Essex-Lopresti injury variant. Closed reduction for the elbow dislocation was performed, and the limb was immobilized at a 90-degree angle with the forearm in a neutral position with a long posterior splint. Three months later complete fracture healing was noted radiologically. One year post-injury full range of motion regarding flexion, pronation, and supination was achieved with only 10 degrees of extension deficit remaining, suggesting a case of Essex-Lopresti injury managed conservatively with excellent results.

Early, Bilateral Re-Rupture of Quadriceps Tendon After Previous Bone-Anchor Repair for Simultaneous, Low-Energy, Bilateral Quadriceps Rupture: A Case Report and Literature Review.

BACKGROUND Bilateral simultaneous quadriceps tendon rupture is a relatively rare injury, more commonly seen in patients older than 50 years and is usually associated with underlying metabolic or inflammatory diseases. CASE REPORT We report the case of an otherwise healthy, 42-year-old man who sustained a bilateral, quadriceps tendon rupture while he was trying to pound a branch of an olive tree into the ground. On clinical examination, a defect in both proximal patella poles was found on palpation, with complete discontinuity of the extensor apparatus. A meticulous surgical repair was performed using 3 bone anchors with an uneventful postoperative rehabilitation. A biopsy specimen taken at surgery showed evidence of chronic inflammation. He had a second episode while walking fast on the beach 3.5 months postoperatively, and presented again with bilateral quadriceps rupture. He was successfully managed with bilateral allograft reconstructions, showing a very good outcome at 18 months of follow-up. Our systematic literature review covering a 20-year period (2000-2020) revealed 10 articles on bilateral quadriceps ruptures in 14 healthy patients without comorbidities. All these injuries occurred in males, with a mean age of 56.8 years, during walking, descending stairs, or participating in recreational sports; the functional outcome was good to excellent in most cases, without any reported re-ruptures. To the best of our knowledge, no similar case has been reported in the literature. CONCLUSIONS Bilateral quadriceps tendons rupture is a rare injury, especially in young patients without associated comorbidities. The risk of recurrence is low, but when it occurs, more complex techniques of reconstruction are needed.
