A review of the literature reveals that incorporating a second screw enhances scaphoid fracture stability by bolstering resistance against torsional forces. All writers suggest that the two screws should be positioned in a parallel manner in all circumstances. Our study presents an algorithm for screw placement, contingent upon the fracture line's type. In transverse fractures, screws are placed parallel and perpendicular to the fracture plane; for oblique fractures, a first screw is placed perpendicular to the fracture line, and a subsequent screw is positioned along the scaphoid's longitudinal axis. The algorithm provides the principal laboratory criteria for maximum fracture compression, which is adaptable to the fracture line's specific direction. The research, involving 72 patients exhibiting analogous fracture geometries, divided them into two groups: those fixed using a single HBS and those fixed with two HBSs. Analysis of the results confirms that the application of two HBS in osteosynthesis procedures produces superior fracture stability. Simultaneous placement of the screw along the axial axis, perpendicular to the fracture line, constitutes the proposed algorithm for fixing acute scaphoid fractures using two HBS. Improved stability results from the even distribution of compression force throughout the fracture surface. selleck chemicals The fixation of scaphoid fractures often involves the use of Herbert screws, utilizing a two-screw approach.
Individuals with congenital joint hypermobility are susceptible to carpometacarpal (CMC) instability in the thumb joint, which can stem from injuries or overuse of the joint. In young individuals, undiagnosed and untreated conditions can serve as a basis for developing rhizarthrosis. The authors' analysis reveals the results of the Eaton-Littler technique. The authors' materials and methods describe a series of 53 CMC joint surgeries performed on patients between 2005 and 2017; these patients had an average age of 268 years, ranging from 15 to 43 years of age. In a group of patients examined, ten cases showed post-traumatic conditions, with forty-three cases presenting instability stemming from hyperlaxity, which was also found in other joints. The operative procedure was carried out via the Wagner's modified anteroradial approach. The patient was fitted with a plaster splint for six weeks after the operation, afterward commencing rehabilitative therapy encompassing magnetotherapy and warm-up treatments. A preoperative and 36-month postoperative evaluation of patients included the VAS (pain at rest and during exercise), the DASH work subscale, and self-reported assessments (no difficulties, difficulties not interfering with normal activities, and difficulties impeding normal activities). The resting VAS score averaged 56, escalating to 83 during exercise, as measured during the preoperative evaluation. At rest, during the VAS assessments, postoperative values at the 6, 12, 24, and 36-month intervals were 56, 29, 9, 1, 2, and 11, respectively. Across the prescribed intervals, the values 41, 2, 22, and 24 were observed under load. Prior to surgical intervention, the DASH score in the work module was 812. At the six-month mark, the score had decreased to 463, continuing to a score of 152 by 12 months following surgery. A subsequent score of 173 was observed at 24 months, and 184 was recorded at 36 months post-surgery, within the work module. Thirty-six months post-operation, self-assessments revealed 39 patients (74%) experiencing no difficulties, with 10 patients (19%) reporting limitations that did not impede their usual activities, and 4 patients (7%) reporting functional impairments that limited daily routines. The collective findings of several surgical studies on post-traumatic joint instability showcase sustained, positive outcomes observed in patients two to six years following their operations. There exists a dearth of investigations into the instabilities present in individuals exhibiting hypermobility-related instability. At 36 months following surgery, our results, obtained via the 1973 method described by the authors, exhibited a comparable outcome to those reported by other authors. We recognize the brief duration of this follow-up and its limitations in preventing the development of degenerative changes long-term. This approach, however, minimizes clinical difficulties and may help delay the progression of severe rhizarthrosis in younger individuals. CMC instability in the thumb joint, while relatively frequent, does not inevitably lead to clinical difficulties for all individuals. Preventing early rhizarthrosis in predisposed individuals requires a diagnosis and treatment of any instability that arises during difficulties. A surgical solution, as implied by our conclusions, is a possibility for obtaining excellent results. Joint laxity in the carpometacarpal thumb joint, also known as the thumb CMC joint, is a key feature of carpometacarpal thumb instability, potentially leading to the degenerative condition known as rhizarthrosis.
Patients experiencing scapholunate (SL) instability often have both scapholunate interosseous ligament (SLIOL) tears and the disruption of supporting extrinsic ligaments. SLIOL partial tears were scrutinized for tear localization, severity grade, and accompanying extrinsic ligament injury Conservative treatment outcomes were evaluated, differentiating by the type of injury sustained. selleck chemicals Past patient records of those with SLIOL tears, without any dissociation, were examined in a retrospective study. Magnetic resonance (MR) images were reassessed to specify tear positioning (volar, dorsal, or both volar and dorsal), the degree of injury (partial or complete), and if any extrinsic ligament injury (RSC, LRL, STT, DRC, DIC) was concurrent. selleck chemicals Magnetic resonance imaging (MRI) was employed to investigate associations between injuries. A year after conservative treatment, all patients were brought back for a re-evaluation. Visual analog scale (VAS) pain scores, Disabilities of the Arm, Shoulder and Hand (DASH) scores, and Patient-Rated Wrist Evaluation (PRWE) scores, both before and after the first year of conservative treatment, were analyzed to determine the treatment response. Among our 104 study participants, SLIOL tears were observed in 79% (82 cases), and 44% (36) of these also exhibited concomitant extrinsic ligament injuries. In the case of SLIOL tears, and every extrinsic ligament injury, the predominant outcome was a partial tear. The volar SLIOL sustained the greatest degree of damage in SLIOL injuries, comprising 45% of cases (n=37). Ligaments of the DIC (n 17) and LRL (n 13) types were prominently affected by tearing, with radiolunotriquetral (LRL) injuries often associated with volar tears and dorsal intercarpal ligament (DIC) injuries frequently coinciding with dorsal tears, irrespective of the duration of the injury. Ligament injuries alongside other structures were correlated with higher pre-treatment VAS, DASH, and PRWE scores compared to situations where only the SLIOL was torn. The impact of the injury's grade, its location, and the presence of extrinsic ligaments on treatment outcomes was insignificant. Test scores experienced a superior reversal in those with acute injuries. For accurate imaging interpretation of SLIOL injuries, the condition of the secondary stabilizers must be carefully examined. Conservative treatment is a viable option for achieving pain relief and functional recovery following partial SLIOL injuries. Partial injuries, especially those of an acute nature, can benefit from an initial conservative treatment strategy, irrespective of tear localization or injury grade, if secondary stabilizers are not compromised. The integrity of the scapholunate interosseous ligament and extrinsic wrist ligaments maintains wrist stability, and carpal instability can be diagnosed through MRI of the wrist. The presence of wrist ligamentous injury, especially the volar and dorsal scapholunate interosseous ligaments, is critical in assessment.
This study's objective is to determine the appropriate position of posteromedial limited surgery in the treatment plan for developmental hip dysplasia, occurring in the interval between closed reduction and medial open articular reduction procedures. We undertook this study to evaluate the practical and radiological results of this method. The retrospective analysis focused on 30 patients presenting with 37 dysplastic hips, categorized as Tonnis grade II and III. The average age, measured in months, of the patients undergoing the surgical procedure was 124. On average, the follow-up period spanned 245 months. Due to the failure of closed techniques to produce a stable and concentric reduction, posteromedial limited surgery became necessary. There was no application of traction before the operation commenced. Post-surgical intervention, the patient was fitted with a human position hip spica cast, which remained in place for three months. The modified McKay functional results, acetabular index, and presence of residual acetabular dysplasia or avascular necrosis were used to assess outcomes. Thirty-five out of thirty-six hips demonstrated satisfactory functional outcomes; unfortunately, one hip exhibited a poor result. The average acetabular index was determined to be 345 degrees before the surgical intervention. The temperature, observed as 277 and 231 degrees in the last X-ray scans performed six months after surgery. A statistically significant variation in the acetabular index was measured, as indicated by a p-value less than 0.005. During the final checkpoint, three hips presented with residual acetabular dysplasia and two hips with avascular necrosis. Developmental dysplasia of the hip, failing to respond to closed reduction, dictates the application of posteromedial limited surgical techniques, mitigating the need for an unnecessarily invasive medial open articular reduction. In keeping with the extant literature, this investigation provides evidence indicating that this method has the potential to reduce occurrences of residual acetabular dysplasia and avascular necrosis of the femoral head.
