The Surgical Treatment of the First Metacarpal Fractures in Adults- About 30 Cases

This is a retrospective review of 30 cases of first metacarpal fractures in adults that were collected in our clinic from March 2015 to March 2018. According to Kapandji 02 cases and direct screw 01 case, it was concerned about surgeons Rolando, Bennett, extra-articular, and diaphyseal stipulation. Following surgery was routine in all patients for six weeks, immobilization was postponed. In 100% of cases, bone fracture reconstruction was achieved in 06 to 08 weeks.

Fractures and dislocation of the base of the thumb metacarpal

Acute traumatic lesions of the first metacarpal base are common, and their consequences can influence the thumb's opposition. The trapeziometacarpal joint reconstruction is therefore highly recommended. Bennett's fractures, small-fragment, and large-fragment are among the first metacarpal fractures, articular three-fragment Rolando, comminutive fractures, extra-articular fractures, and extra-articular fractures of the first metacarpal's base. Percutaneous surgery, open surgery, and arthroscopic surgery are all examples of surgical methods: percutaneous surgery, open surgery, and arthroscopic surgery.

Biomechanical Evaluation of Metacarpal Fracture Fixation: Application of a 90° Internal Fixation Model

Purpose Complications of metacarpal fracture repair rise in proportion to the severity of the initial injury and the surgical fixation technique's invasiveness. This paper explores the possibility of minimizing internal fixation construct size and soft tissue dissection, as well as maintaining the benefits of stable internal fixation in a biomechanical model. Means of failure For the dorsal plating system and 358. 87. 1 N for the orthogonal structure. Mean failure displacement was 3. 3 mm for the dorsal plating work and 4. 1 mm for the orthogonal construction, respectively. Mean stiffness was 161. 350. 0 N/mm for the dorsal plating system and 122. 146. 6 N/mm for the orthogonal construction. Mean failure time was 3. 091. 06 Nm for the dorsal plating system and 3. 14 Nm for the orthogonal structure. Conclusions The orthogonal structure and the standard dorsal plate build behaved comparably when subjected to apex dorsal bending.

Early Pleistocene third metacarpal from Kenya and the evolution of modern human-like hand morphology

Significance Kaitio, Kenya, dates back to 1. 42 Mya and provides evidence for the evolution of the human hand more than 600,000 yrs earlier than ever reported. This bone shows a styloid process, which is part of a distinctively human rearrangement of the wrist that is associated with increased hand function when making and using tools.

A Comparison of Outcomes of Reconstruction of Palmar versus Dorsal Defects of the Thumb Using a First Dorsal Metacarpal Artery Flap with a Cutaneous Bridge Segment

Background: The aim of this review is to compare the results of palmar versus dorsal fractures of the thumb made using the first dorsal metacarpal artery flap with a cutaneous bridge segment. In this report, all FDMA flaps created at our center for reconstruction of traumatic thumb injuries in the period from November 2017 to May 2019 were included. The mean static 2-PD was 9. 35 mm, cortical reorientation was complete in six patients, paresthesia score at the flap was 0. 27, and at the donor site was 0. 36 percent. Except for the cosmetic appearance of the flap that was rated higher for dorsal defects, there were no differences between palmar and dorsal defects. Conclusion: The FDMA flap, which was built with a cutaneous bridge segment, was used to provide safe, single-stage reconstruction of dorsal and palmar thumb injuries with positive results. Patients liked the cosmetic result of flaps used for dorsal reconstruction more than others.

Precision of the Wilson corrective osteotomy of the first metacarpal base using specific planning and instruments for treatment of basal thumb arthritis

Introduction to the Arthritis of the Basal thumb is a common disorder that also affects younger patients. A 20°-30° closing wedge osteotomy of the first metacarpal bone to unload the trapeziometacarpal joint was described as a 20°-30° closing wedge osteotomy of the first metacarpal bone to unload the trapeziometacarpal joint. The aim of this study was to investigate the proximal extension osteotomy of the first metacarpal bone using patient-specific planning and technologies. All patients who underwent proximal metacarpal osteotomy for basal thumb arthritis at our tertiary referral center were retrospectively accepted. At a mean follow-up duration of 33–16 months, there were eight Wilson osteotomies in six patients. The MHQ for satisfaction was 7728, the postoperative MHQ for general hand function. Conclusion The combined extending and ulnar adducting osteotomy with patient-specific protocols and instrumentation provides a safe cure for early-stage thumb arthritis.

Mini External Fixator Assisted Metacarpal Lengthening With The Distraction Method

Abstract Phalangeal brachydactyly, which is triggered by the abnormal growth of the metacarpal, is characterized by shortness that can be seen in a single finger or in both fingers of the hands. A twelve-year-old girl was admitted to our clinic with complaints of shortness in the left hand's fourth finger. The results from progressive distraction without bone grafting are near to perfect in patients under the age of twenty years old. Although the technique of successfully lengthening metacarpal fractures in children is straightforward, stringent guidelines should not be ignored.

600 Reconstruction of Finger Contracture with an Expanded Dorsal Metacarpal Artery Perforator Flap

Abstract Introduction The first dorsal metacarpal artery perforation flap is often used to mask painful bone, tendon, and neurovascular structures in the hand following injury and fire. The DMCAP flap's size and breadth are limited, but rotation arc usually allows to cover defects up to middle phalanx. Expansion of the DMCAP flap has not been reported in the literature, and it may be a way to increase flap stability and size in order to mask flaws up to distal phalanx. We'll first DMCAP and a case of electric burns in with flexor contracture in this report. Methods A nine-year-old male patient presented to our clinic with the complaint of inability to extend the left hand's second finger after an electrical burn. With 1 ml of isotonic three days a week from the second postoperative week, the tissue expander was inflated. Results In the second session, contractures at the level of the left hand 2nd finger DIP and PIP were eliminated. Conclusions: Extra tissue can be obtained by free flaps or tissue expanders in cases where the tissue defect cannot be closed with loco regional flaps. Among the benefits of the expanded DMCA flap are primary closure of the donor area, correct flap thickness for the finger, and visually pleasing results.

Radiographic Thumb Metacarpal Subsidence Following Ligament Reconstruction With Tendon Interposition and Suture-Only Suspension Arthroplasty in the Treatment of Basal Joint Arthritis

Osteritis in the thumb carpometacarpal joint is a common cause of osteoarthritis. This article is a retrospective review of 23 patients who underwent thumb CMC arthroplasty following thumb CMC arthroplasty. At a preoperative time point, radiographs were taken from real trapezial height, as well as trapezial height normalized to capitate, thumb metacarpal, and proximal phalangeal heights. Mean trapezial height decreased from approximately 12 to 5 mm in both groups, but there were no differences between LRTI and SSA at each time point. Both normalized trapezial heights revealed differences from preoperative to greater than six months postoperative time points, but there were no differences between LRTI and SSA. Conclusions: Ligament reconstruction with tendon interposition and SSA display equivalent true and normalized trapezial heights over a greater than 6-month postoperative time course.

OUTCOMES OF FIXATION METACARPAL FRACTURES USING BIOABSORBABLE IMPLANTS

The study of the most effective fixation of fractures of the hand bones in domestic and international literature is also extensive, with Tactics of fractured metacarpal bones. The aim of the investigation was to assess the results of fixation of 2-5 metacarpal fractures using bioabsorbable implants. Objects and methods: A retrospective examination of 40 patients with fractured closed fractures of 2-5 metacarpal bones was published. Patients had a metacarpal fracture three months after surgery, with all patients displaying joint frustration.
