Comparative analysis of the effects of AO mini-plate and Kirschner wire pinning in the metacarpal fractures: A retrospective study.

ABSTRACT: The aim of this study was to investigate the clinical effect of AO miniplate screw internal fixation and Kirschner wire (KW) in the treatment of metacarpal fractures.We retrospectively analyzed the clinical data of 590 metacarpal fracture patients admitted to our hospital from March 2016 to March 2019. Among them, 290 patients were treated with KWs; 300 were treated with AO microplate internal fixation. The clinical, radiological results, time of surgery, and complications were observed and compared between the 2 groups.The imaging characteristics and preoperative fracture types of the 2 groups were similar and comparable (P > .05). The operation time, length of hospital stay, and fracture healing time of AO group were shorter than those of KW group, and the differences were statistically significant (41.22 ±â€Š7.23 vs 25.64 ±â€Š6.29; 7.13 ±â€Š2.38 vs 5.26 ±â€Š1.71; 67.43 ±â€Š22.01 vs 52.57 ±â€Š17.46, P < .05). In addition, the incidence of postoperative complications in AO group was lower than that in KW group (8.3% vs 15.2%, P < .05). In terms of surgical knuckle extension, flexion, and total mobility (compared with the uninjured hand), patients in the AO plate group were significantly improved compared with patients in the KW group, and the difference was statistically significant (4 vs 10 degree; 19 vs 10 degree; 14 vs 29 degree, P < .05); The average degree of finger rotation deformity in AO plate group was significantly lower than that in KW group (1 vs 6 degree, P < .05). In terms of grip strength (compared with the healthy hand), the average grip strength of AO plate group was significantly higher than that of KW group (93% vs 83%, P < .05). Patients in the OA plate group had a lower Disabilities of the Arm, Shoulder and Hand score (P < .05).Compared with KW fixation, AO mini-plate and screw fixation for the metacarpal fracture has a better effect, which can effectively shorten the operation time and reduce the trauma to patients. It can provide patients with better stability and realize the early movement of the palm, promote fracture healing and joint function recovery; it can reduce the incidence of postoperative complications, which has certain safety. In addition, it can effectively reduce the risk of poor finger rotation.

Low-cost procedure for deformity correction in rheumatoid hands.

BACKGROUND: Surgical correction of ulnar drift of metacarpo-phalangeal joint (MPJ) due to Rheumatoid arthritis (RA) is conventionally done by silicon joint arthroplasty which is expensive and may be associated with many complications. We report the outcome of low-cost autologous interpositional arthroplasty. MATERIAL AND METHODS: Five patients (8 hands, 32 arthroplasties) underwent correction of ulnar drift of MPJ by dorsal capsule interpositional arthroplasty. Results were assessed according to the degree of recovery of movement at the MPJ and correction of ulnar drift. Functional improvement was graded as excellent, good and fair. Pain alleviation was assessed by visual analogue score (VAS) score. RESULTS: Excellent results were seen in 3 patients (5 hands, 20 arthroplasties), good in 1 patient (2 hands, 8 arthroplasties) and fair in 1 patient (1 hand, 4 arthroplasties). VAS score for pain decreased from mean preoperative 8.2/10 to 1/10. On average follow up of 1.4 years there was good hand function, no recurrence of deformities and patients were pain free. CONCLUSION: Interpositional arthroplasty for MPJ using dorsal capsule for correction of post RA ulnar drift is a low-cost option which improves the hand function and cosmesis. Additionally, it avoids all the complications related with the use of silicon joints.

Prosthetic Arthroplasty of Proximal Interphalangeal Joints for Treatment of Osteoarthritis and Posttraumatic Arthritis: Systematic Review and Meta-Analysis Comparing the Three Ulnar Digits With the Index Finger.

Background: It is common teaching that treatment of index finger alone is a relative contraindication for arthroplasty of the proximal interphalangeal joint (PIPJ). However, limited data exist reporting the digit-specific complication of PIPJ arthroplasty for the treatment of osteoarthritis or posttraumatic arthritis. The purpose of this article is to perform a systematic review and meta-analysis of the literature to assess whether the 3 ulnar digits may bear a similar instability and complication profile. Methods: Systematic searches of the MEDLINE, EMBASE, and Cochrane computerized literature databases were performed for PIPJ arthroplasty specifying by digit. We reviewed both descriptive and quantitative data to: (1) report aggregate instability and instability-related complications after non-index digit PIPJ arthroplasty; and (2) perform statistical testing to assess relative rates by digit and compared with index digits. Results: Computerized search generated 385 original articles. Five studies reporting digit-specific instability-related outcomes of silicone, pyrocarbon, or metal surface arthroplasty on 177 digits were included in the review. Meta-analysis demonstrated a 29% instability rate for long digits (n = 65), 6% for ring digits (n = 53), and 6% for small digits (n = 17), compared with 33% for index digits (n = 42). There was no difference in the overall deformity, instability, and complication rates of long versus index fingers (P = .65). Conclusions: Instability-related deformity and complication rates of long finger PIPJ arthroplasty may not be different from that of the index finger. Treatment of the long finger may be a relative contraindication to PIPJ arthroplasty. Future biomechanical and clinical studies are needed.

Minimally invasive modified Camitz opponensplasty for severe carpal tunnel syndrome.

PURPOSE: We aimed to compare the clinical results and the complications between the minimally invasive modified Camitz opponensplasty and the conventional Camitz opponensplasty for severe carpal tunnel syndrome (CTS), and to evaluate the efficacy of the modified technique for CTS. METHODS: Twenty-eight hands in 24 patients with severe CTS who had disorder of the thumb opposition with thenar muscle atrophy (group 1) were treated by minimally invasive modified Camitz opponensplasty, passing the transferred palmaris longus (PL) tendon under the abductor pollicis brevis (APB) fascia using only palm and thumb incision, and no incision to either wrist crease or forearm. Ten hands in 10 patients (group 2) were treated by the conventional Camitz opponensplasty. Clinical evaluation was made by comparing the results before and after surgery for the angle of the thumb palmar abduction, pinch power, and grip strength. RESULTS: All clinical findings significantly improved after surgery compared with before surgery in all patients. In group 1, there were no complications including transferred tendon bowstring, painful wrist scar, or injury to the palmar cutaneous branch of the median nerve in all hands. Conversely, patients in group 2 had four painful wrist scars and nine bowstrings of the transferred tendon. CONCLUSIONS: Several complications have been considered to attribute to the long incision and an extensive dissection crossing the wrist crease from the palm to the wrist in the conventional Camitz procedure. The current modified Camitz opponensplasty by minimally invasive incision without straddling the wrist crease is a simple and effective procedure that can decrease the risk of painful scar around the wrist crease in severe CTS patients with disorder of thumb opposition. Additionally, this technique, by passing the transferred PL tendon under the APB fascia, is useful in restoring the thumb opposition immediately, and in preventing the bowstringing of the transferred tendon.

Analysis of surgical results and of residual postoperative deformities in preaxial polydactyly of the hand.

PURPOSE: Polydactyly is the most common congenital anomaly of the hand. It may occur as a separate event or as part of a syndrome, with preaxial polydactyly of the hand (or thumb duplication) being the most common among Caucasians. The present study analyzed the surgical results and the residual postoperative deformities of patients with thumb duplication. METHODS: Thirty-one patients with duplicated thumbs were surgically treated from January 2002 to April 2008 and 19 of them, who had returned during the late postoperative period, were evaluated. Each case was typed according to Wassel's classification into seven types and the most common category was type IV. Removal of radial component was done in 18 patients aged on average 51 months. RESULTS: Patients and parents were satisfied with both the functional results and the appearance of the reconstructed thumb. In the subjective evaluation of residual deformities, axis deviation and residual prominence were commonly found. There were coherencies in data between both subjective and objective outcomes. The children that had difficulty in holding very small objects in the subjective functional result were the same children with residual deformities in the objective result. Patient's age at surgery and Wassel's type influenced the analysis of residual postoperative deformities. There was statistically significant difference in cases of type VII and in patients operated at more than three years of age. Correlation between type VII and patient's age at time of surgery was found. The children with type VII duplication were operated later. CONCLUSIONS: For a better result, surgical correction should be performed before three years of age, thus correcting all the changes detected, mainly in type VII, in order to reduce the incidence of residual deformity. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

[SURGICAL TREATMENT OF CONGENITAL TYPE V THUMB SYNDACTYLY].

OBJECTIVE: To study the effectiveness of surgical treatment of congenital type V thumb syndactyly. METHODS: Between March 2010 and May 2015, 12 cases of congenital type V thumb syndactyly were treated. There were 7 males and 5 females, aged from 1 to 25 years (mean, 8 years). The right thumb was involved in 8 cases, and the left thumb in 4 cases. There were 2 cases of radial type, and 10 cases of ulnar type. The basement of polydactylism was far away from the carpometacarpal joint in 7 cases, and was close to the carpometacarpal joint in 5 cases (slight ulnar deviation in 1 case). X-ray films showed that the main first thumb metacarpal bone and trapezium fitted well, and 2 cases had the first metacarpal bone deformity. Preoperative individualized treatment plan was made, and polydactylism was excised by the "S" or "Z" incision and simultaneous reconstruction of thenar muscle insertions or adductor muscle insertions was performed; if necessary, wedge osteotomy was used for correction. RESULTS: All incisions healed by first intention with no complication. All cases were followed up 6 to 24 months (mean, 12 months). The thumb appearance, flexion and extension, the function of opposition, abduction function were improved significantly in 11 cases with no scar contracture deformity, small first web space, and deviation deformity. One case had slightly narrow first web space. According to hand function criterion, the results were excellent in 10 cases, good in 1 case, poor in 1 case; excellent and good rate was 91.7%. CONCLUSIONS: Based on the condition of the type V thumb syndactyly, the individualized treatment plan is made, which can better restore the shape and function of the thumb.

Single forearm radius and ulna asymmetric lengthening in multiple cartilaginous exostoses: a case report and a long-term follow-up.

We describe one case of forearm deformity in a patient affected by multiple cartilaginous exostoses - also known as the forearm 'candy stick deformity'. Surgical treatment usually focuses on the correction of the wrist deformity without correcting the forearm shortening, the latter not being given the same consideration as lower limb shortening. In the presented case, radius and ulna corticotomies were performed and distal forearm deformity and shortening were corrected by two independent monoaxial external fixators, with full pronosupination. It is our belief that simultaneous treatment of forearm shortening and deformity not only results in an improved clinical and functional result but also provides significant psychological benefit. We recommend a long-term follow-up.

Surgical reconstruction of an unstable rheumatoid thumb deformity. A case report.

The thumb is frequently impaired in rheumatoid arthritis. This leads to major disability in affected patients. Through a clinical case, we describe a reconstructive strategy for a three-joint adduction thumb deformity that caused instability of the interphalangeal and metacarpophalangeal joints, without cartilaginous lesion. Ulnar collateral ligament destruction was treated by a bone-ligament-bone graft at the interphalangeal joint and by a Littler ligamentoplasty at the metacarpophalangeal joint. The trapeziometacarpal lesion was treated by trapeziectomy in combination with suspension ligamentoplasty. Clinical and radiological assessments at 22 months of follow-up revealed good outcomes. This technique is a new option to include in the reconstructive treatment for thumb instability, particularly when caused by rheumatoid arthritis.

Severe camptodactyly: A systematic surgeon and therapist collaboration.

INTRODUCTION: Although common, the treatment of camptodactyly is controversial. PURPOSE: Our purpose is to delineate a logical stepwise treatment plan based on corresponding components of the pre-operative and intraoperative evaluation of camptodactyly. In addition, describe structure rehabilitation plan utilizing the same stepwise evaluation. METHODS: With the use of a retrospective cohort study design, we reviewed 18 consecutively operated digits in twelve patients with camptodactyly affecting the proximal interphalangeal (PIP) joint. There were five girls and eight boys, averaging eight years of age (range: 9 months to 15 years) at surgery. RESULTS: Surgery corrected flexion contractures with mean post-operative flexion contracture of 3° (range 0-25°) at mean follow-up of 11 months (range 3-32 months). 15 of 18 digits achieved full active PIP extension. DISCUSSION: By employing a detailed clinical assessment to guide surgical treatment followed by focused therapy, we have markedly improved flexion contractures in digits with moderate to severe camptodactyly. CONCLUSIONS: Hand therapy is essential to maintain and further surgical improvement of passive extension and to regain active extension following surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Reconstructive surgery in children to correct ulnar claw hand deformity due to leprosy.

OBJECTIVES: To study the impact of tendon transfer surgery for ulnar claw hand correction in children with leprosy. SUBJECTS AND METHODS: All the children who underwent reconstructive surgery for ulnar nerve paralysis during the period 2007 to 2012 were included in the study. Unassisted angle, grasp contact, pinch contact and functional assessment were the main outcome measures. All the surgical procedures were performed by the same surgeon and pre- and post-operative therapy protocol was same for all the patients. A common surgical audit form was used to record assessments for all the patients. RESULTS: In this case series, 82 hands of 79 patients with ulnar paralysis were included. All the children had lasso surgery. In 83% of hands, flexor digitorum superficialis of middle or ringer finger was used, while in the remaining patients palmaris longus or extensor carpi radialis longus with fascia lata graft was used as the motor tendon. The unassisted angle decreased in all the patients, indicating correction of claw fingers. Hand function improved after surgery and it showed steady progress during follow-up. CONCLUSION: The deformity due to leprosy in the hands of children is a tragedy as it hampers the use of hands in daily routine activities, school work and other social interactions. Tendon transfer surgery should be done on children to correct established clawed fingers as it yields good results and helps in facilitating hand function to complete daily activities and lead a normal life.

The Neurological Hand Deformity Classification for children with cerebral palsy.

BACKGROUND/AIM: The purpose of this study was to evaluate the reliability of the Neurological Hand Deformity Classification and use it to describe changes in hand deformity over time in children with cerebral palsy. METHODS: We identified 114 video clips of 26 children with cerebral palsy, aged 1-18 years (mean = 8.4, SD = 4.2), performing upper-limb tasks at multiple time points (n = 3-8) at least 6 months apart. Using the Neurological Hand Deformity Classification, three observers classified hand deformity in the video clips. Inter- and intra-observer reliabilities were estimated using Fleiss and Cohen's kappa (κ) and the temporal changes in classification of hand deformity were investigated. RESULTS: Inter- and intra-observer reliability respectively were κ = 0.87 and κ = 0.91. Hand deformity was identified in all children at all time points, even before the age of 2 years. Ten children did not change hand classification, wrist flexion increased in eight, and eight showed changes from wrist flexion to extension or vice versa. CONCLUSIONS: The Neurological Hand Deformity Classification is a reliable tool to classify hand deformity in children with cerebral palsy. For more than one-third of children hand deformity classification did not change. For the remaining children, two patterns of change in hand deformity over time were identified. It is recommended that children with cerebral palsy involving their upper limbs be monitored regularly. SIGNIFICANCE OF THE STUDY: This is the first study to document longitudinal changes in hand deformity in children with cerebral palsy.
