ABSTRACT
Introduction: Avascular necrosis of the lunate bone has been extensively researched, although the etiology of the condition remains controversial. Even though many treatments for the disease exist, a better understanding of the pathophysiology can improve our decision-making between preventive and therapeutic measures. Various hematological disorders have been found to predispose for Kienböck's disease. On the other hand, there has not yet been any reference in literature to a relationship between this condition and hereditary hemochromatosis (HH). Case Report: We present two cases of Kienböck's disease in two patients who are third-degree relatives and diagnosed with HH. A 61-year-old Caucasian female patient with type 1 HH presented with symptomatic Kienböck's disease on the left side. The patient is a third-degree relative of a 51-year-old male Caucasian patient with Kienbock's disease on the right side, known as having the same hereditary hematological condition. Conclusion: Our findings suggest a potential correlation between the aforementioned conditions. The prevalence of these coexisting pathologies should be studied further.
ABSTRACT
Emerging advances in immersive virtual reality incorporating optical hand-tracking present promising potential for application in orthopedic hand therapy. The system is designed to analyze hand movements, enabling users to "use" their hands virtually in any fabricated setting. This article, supplemented with videos, examines practical applications of immersive virtual reality in routine hand therapy and provides a scientific presentation of the interaction of immersive virtual reality with our physiological and neurological systems. Indications for immersive virtual reality use, critical evaluations and recommendations are comprehensively discussed. Immersive virtual reality has the potential to evolve into a standard treatment modality in orthopedic hand therapy.
ABSTRACT
BACKGROUND: In patients with symptomatic trapeziometacarpal (TMC) joint arthritis resistant to conservative treatment, surgical treatment can be advised. One of the many surgical treatment options is TMC arthroplasty. The Arpe prosthesis is one example of these TMC arthroplasties. METHODS: This retrospective study evaluated patients who underwent TMC arthroplasty with the Arpe prosthesis after a minimum of 15 years of follow-up. Clinical, radiologic, and qualitative outcomes were assessed for 43 Arpe arthroplasties in 41 patients, of whom 2 had bilateral arthroplasties. The female to male ratio was 39:4. The mean follow-up time was 197 months (range = 180-225). RESULTS: The cumulative survival rate after a mean of 16.5 years was 84%. Seven failures (16%) were registered, of which 5 during the first 3 years after primary surgery. All patients were successfully converted to a trapeziectomy. Quick Disabilities of the Arm, Shoulder and Hand score improved with 44.9 points and visual analogue pain score with 97% and 91% at rest and during exercise, respectively. CONCLUSIONS: This series demonstrates that thumb arthroplasty is a reliable long-term solution for thumb base arthritis, with significant pain reduction and functional improvement, even after 15 years of follow-up.
ABSTRACT
Digital mucous cysts are common, benign and highly recurrent tumors of the distal interphalangeal joints of the fingers and often associated with osteoarthritis. Multiple treatment modalities have been described, but still no consensus is stated. In the absence of degenerative changes, we promote a novel non-surgical approach. The aim of this study was to examine all patients with digital mucous cysts without underlying osteoarthritis, undergoing this injection technique and to assess outcome and complications of this procedure. This was a single center study (2018-2019) of 17 patients who received a long needle trajectory aspiration and injection for treatment of digital mucous cysts. Exclusion criteria were prior surgical treatment, post-traumatic cyst formation and the presence of radiographic distal interphalangeal joint osteophytosis. A total of 15 patients were found eligible for inclusion. The patient reports were retrospectively analyzed with a follow-up of 6 months. The primary study outcome was resolution of the cyst; secondary outcomes were complications of the procedure. Twelve (80%) resolved completely and three (20%) had limited local recurrence at 6 months. No complications were reported. None of the patients with limited recurrence desired further treatment. We believe that this technique offers a non-invasive, low-cost treatment option for digital mucous cysts, particularly in the subset of patients with ample evidence of degenerative articular changes in the distal interphalangeal joint. The described technique can be performed in an office-based setting and avoids typical surgical as well as aspiration-associated complications.

OBJECTIVE: Management of recurrent Dupuytren's disease of the little finger is challenging. Various treatment modalities have been proposed: external fixation, local skin flap, dermofasciectomy, or even amputation. An alternative surgical technique was introduced by Honecker et al. in 2016 and refined by Raimbeau et al. in 2019, consisting in resection of the middle phalanx and shortening arthrodesis. We modified the technique by combining arthrodesis with a limited fasciectomy of the abductor and/or pretendinous cord in the fifth ray to improve cosmetic and functional outcomes. METHODS: Patients with severe recurrent Dupuytren's disease of the little finger (Tubiana stage III/IV) were treated with proximodistal interphalangeal arthrodesis, combined with limited fasciectomy. Range of motion was assessed preoperatively and postoperatively. QuickDASH and a VAS were assessed to determine overall function and pain respectively. Radiographic evaluation was made at 6 and 12 weeks postoperatively. RESULTS: Thirteen patients were eligible for inclusion. Mean age was 69 years (range 49-87). Radiographic consolidation was obtained at a mean 58 days (range 27-97). Full extension of the metacarpophalangeal joint was achieved in 11 patients and full adduction in 12. Mean active flexion was 94° (range 90-100). QuickDASH scores decreased from 18 to 12 after surgery. Pain scores were low and unchanged. CONCLUSION: By combining proximodistal interphalangeal arthrodesis with limited fasciectomy through a volar approach, finger extension improved, and fixed abduction was also treated. The combined volar and dorsal approach did not induce vascular impairment or other complications.

BACKGROUND: Although carpal tunnel syndrome (CTS) is the most common form of peripheral entrapment neuropathy, its pathogenesis remains largely unknown. An estimated heritability index of 0.46 and an increased familial occurrence indicate that genetic factors must play a role in the pathogenesis. METHODS AND RESULTS: We report on a family in which CTS occurred in subsequent generations at an unusually young age. Additional clinical features included brachydactyly and short Achilles tendons resulting in toe walking in childhood. Using exome sequencing, we identified a heterozygous variant (c.5009T>G; p.Phe1670Cys) in the fibrillin-2 (FBN2) gene that co-segregated with the phenotype in the family. Functional assays showed that the missense variant impaired integrin-mediated cell adhesion and migration. Moreover, we observed an increased transforming growth factor-ß signalling and fibrosis in the carpal tissues of affected individuals. A variant burden test in a large cohort of patients with CTS revealed a significantly increased frequency of rare (6.7% vs 2.5%-3.4%, p<0.001) and high-impact (6.9% vs 2.7%, p<0.001) FBN2 variants in patient alleles compared with controls. CONCLUSION: The identification of a novel FBN2 variant (p.Phe1670Cys) in a unique family with early onset CTS, together with the observed increased frequency of rare and high-impact FBN2 variants in patients with sporadic CTS, strongly suggest a role of FBN2 in the pathogenesis of CTS.

We report the case of a 14-year-old boy with an isolated Salter-Harris type IV physeal fracture of the distal ulna. Following failed closed reduction, transition to open reduction and pin fixation was required. Six-month follow-up showed a favourable clinical evolution. Evidence suggests that long-term follow-up is needed because of the increased risk of premature physeal closure and subsequent growth disturbances associated with this type of injury.
ABSTRACT
Primary bone and soft tissue tumours are rare in a non-referral teaching department. The incidence varies greatly among the different subtypes and every Orthopaedic surgeon will encounter one or more benign or malignant lesions during their careers. History, clinical examination and technical investigations are of great importance, but basic knowledge and basic principles are necessary for a correct clinical practice. It was the purpose of this study to raise awareness towards such pathology by exemplifying our cases from a two-year period in our community-based hospital and if necessary, to refer patients to specialised sarcoma centres.

The purpose of this study was to evaluate the safety and the effectiveness of a new modified anconeus transfer technique in revision surgery for refractory lateral epicondylitis of the elbow. A modified anconeus muscle transfer was performed in nine patients with persistent symptoms after previous surgical release of the common extensor origin. The original technique was modified by using only half of the anconeus muscle. Patients were clinically evaluated, including quickDASH score and grip strength measurement. At a mean follow up period of 36 months, 4 patients had an excellent result, 3 a good result and 1 a poor result. All patients rated their clinical situation as better than before surgery. All but one patient said to be happy with the result and they would undergo the procedure again. The mean quickDash score at the follow up was 10.6 (SD 14.4). No complications were observed. The modified Anconeus muscle transfer is a safe and effective procedure in patients with persistent lateral epicondylitis complaints after a previous surgical release.
ABSTRACT
We report the case of a 47-year-old man who presented with a pathologic fracture of the middle phalanx of the fourth finger. The treatment of this juxta-articular lesion close to the proximal interphalangeal joint was performed in 2 stages. First, a biopsy was carried out combined with fixation of the fracture by a Suzuki dynamic external fixator. After 6 weeks, a curettage of the confirmed enchondroma was performed with iliac crest grafting, leaving the external fixator for another 4 weeks. With a follow-up of 48 months, a satisfying functional result has been obtained with a remarkable remodeling of the painless proximal interphalangeal joint.

Lower leg trauma is a frequent pathology in the emergency department of every hospital. Given the lack of a general consensus and the poor knowledge in the current use of pharmacological thromboprophylaxis, a cross-sectional, observational and epidemiological disease registry with 261 patients included by 16 centers was designed. These patients presented with a lower leg trauma and all needed a cast or splint to immobilize the injured leg. First, the different risk factors for thromboembolism and the type of injury in this population are mapped out. Secondly, the importance of both parameters in the decision making process to use or not to use prophylaxis in a lower leg trauma is discussed. In the absence of clear guidelines, the presence of thromboembolic risk factors (type and number in a specific patient) and the type of injury are leading the decision to use thromboprophylaxis in emergency department of non-university hospitals, in patients with a lower leg trauma receiving a cast or splint to immobilize an injured leg.

Determination of thumb length in children is helpful in the diagnosis of congenital syndromes and in the evaluation of the outcome after reconstruction of the thumb in congenital or post-traumatic conditions. Two hundred and sixty-two normal children were examined with a simple technique to procure information related to age, the thumb length dominance and sex. Out of all these, data growth curves and percentiles were constructed as a guideline to detect pathologies and syndromes in children.
