Retrospective study of Ishiguro's technique for mallet bone finger in children: long-term follow-up and analysis of predictors in outcomes.

PURPOSE: There is no consensus on the optimal treatment of bony mallet finger in the paediatric population due to a lack of studies in children. The Ishiguro technique is simple and less invasive, and treatment with K-wire fixation seems to provide better results for extension lag in bony mallet finger according to the literature. A retrospective cross-sectional study with long-term follow-up was performed to evaluate the functional and clinical outcomes of this method in children. Preoperative and intraoperative predictors of outcome were investigated. METHODS: From June to December 2022, we evaluated 95 children who underwent extension K-wire block from 2002 to 2012. Eighty-four children were included (mean age 14.8 ± 1.68 years) for a mean long-term follow-up of 11.6 ± 2.3 (8-16) years. Clinical and radiographic features were assessed. Pain and functional outcomes were assessed using Crawford criteria, range of motion (ROM) at the distal interphalangeal joint (DIPJ), loss of extension, and VAS scale. Univariate and multivariate regressions were used to assess which variables might predict the worst outcomes at long-term follow-up. RESULTS: Bone union and pain relief were always achieved. There were no complaints of potential growth impairment or nail deformity. 82.1% of patients showed excellent and good results. Fifteen patients had fair results. CONCLUSIONS: Although there are currently no significant differences between surgery and orthosis in adults, the Ishiguro technique is more effective in children when it comes to outcomes in the treatment of mallet fingers. A high percentage of excellent and good results were achieved, and no epiphyseal damage or nail deformity was reported. A strong and significant correlation was found between the worst outcomes and either delayed treatment time or excessive flexion angle.

Retrospective Review of Long-term Outcomes of Patients Undergoing CMC Arthroplasty With Interposition Scaffold.

Background: The treatment of rhizarthritis involves several surgical techniques; among them, bioabsorbable scaffolds have begun to be proposed to avoid the use of other biological tissues or artificial permanent devices. Methods: In this study, we evaluated the long-term outcomes of poly-ld-lactic acid scaffold in interposition arthroplasty in a series of patients treated in our department. Results: Strength, range of motion, and pain improved after the intervention and lasted over the years; nonetheless, most of the radiographs showed a progressive collapse of the first metacarpal. Conclusions: Despite radiological findings, we believe that poly-ld-lactic acid scaffold can be considered a good alternative to traditional trapeziectomy with tendon interposition and suspensionplasty, with long-lasting satisfactory clinical results.

Digital Replantations: Comparison Veins Anastomoses first versus Arteries Anastomoses first.

PURPOSE: This retrospective study analyses the effect performing veins anastomoses before arteries anastomoses in digital replantation. PATIENTS AND METHODS: 38 adult patients with replantation of 12 thumbs and 39 fingers, in whom the veins anastomoses were performed prior to the arteries anastomoses, were compared with 29 patients with replantation of 9 thumbs and 30 fingers, in whom the arteries anastomoses were done first, with respect to the survival rate, total active motion, grip strength, and duration of the replantation. RESULTS: There was no significant difference between the two groups with respect to the survival rates, total active motion, and grip strength, while the duration of the replantation was significantly shorter in patients, in whom the veins anastomoses were performed prior to the arteries anastomoses (2 hours and 50 minutes versus 3 hours and 42 minutes; p < 0.001). CONCLUSION: Performing veins anastomoses before arteries anastomoses in digital replantations reduces the replantation time significantly without influencing the survival rate and the clinical outcome.

Upper limb traumatic injuries: A concise overview of reconstructive options.

Different options for upper limb reconstruction are described in literature: advancement or rotation flaps, regional flaps and free flaps are the most common. Local and regional flaps can represent the reconstructive options for small defects while large wounds require the use of free flaps or distant pedicled flaps. In case of large wound, the use of free flaps rather than distant pedicle flaps is usually preferred. To choose the best reconstructive option, it is essential for the surgeon to have a general overview about the different methods. In this review the Authors will refer to the most commonly used methods to cover soft tissues injuries affecting the dorsum and the palm of the hand and the forearm (excluding fingers). The aim is to show all flap reconstructive options so as to support the inexperienced surgeon during the management of traumatic injuries of the upper limb.

Median Nerve Injury Caused by Screw Malpositioning in Percutaneous Scaphoid Fracture Fixation.

An unusual complication of percutaneous fixation of a schapoid fracture in a 36-year-old man is described. After this surgery, the patient complained of numbness and tingling within the median nerve distribution and thenar weakness. An Electromyography showing moderate CTS had led to carpal tunnel decompression, which resulted unsuccessful. When the patient presented to us, both sensory and motor median nerve impairment were present, interfering with his professional activity. A computed tomography scan performed to assess the scaphoid screw position, showed that the screw had been placed volar to the scaphoid, adjacent to the median nerve. Surgery confirmed median nerve compression by the screw, especially during complete wrist extension. The surgical removal of the screw led to immediate improvement of both the motor and sensory functions of the nerve, with complete clinical restoration of nerve function and resolution of the symptoms 2 months postoperatively.

Surgical correction of crossover deformity of the second toe: a technique for tenodesis.

Twenty-seven patients with 30 crossover toe (COT) deformities of the second toe were evaluated. This deformity in the transverse and sagittal planes at the second metatarsophalangeal joint may be caused by hindfoot pronation. Compression of the lateral plantar nerve may produce incompetence of the second dorsal interosseous muscle and an increased extension-adduction pull by the lumbrical and first dorsal interosseous muscles. A surgical procedure for tenodesis is described to correct these deformities and restore the extrinsic-intrinsic musculotendinous balance at the second MTP joint. Our results are encouraging, with 83% good or excellent results. There was one recurrence.
