Radiological and clinical analysis of Madelung's deformity in children

[Physiolysis with Resection of Vickers' Ligament in Adolescent Patients with Madelung's Deformity]

BACKGROUND

Madelung's deformity is a congenital or acquired growth disorder of the forearm that can lead to significant impairments in the quality of life of affected patients. Various surgical treatment options for the condition have been described in the literature. This study aimed to investigate whether physiolysis with resection of the Vickers ligament can successfully halt the progression of the disease in a cohort of young patients, as would be expected based on existing literature on this topic.

MATERIAL AND METHODS

An analysis was performed on the records of all patients with Madelung's deformity who were primarily treated with physiolysis with resection of the Vickers ligament between January 2001 and June 2017. Patients were invited for follow-up examinations, and surgical outcome was assessed. Parameters evaluated included pain at rest and under load, range of motion of the wrists, and activity level. Additionally, standard X-rays and radiological measurements were performed for each operated wrist. The collected data was compared with the preoperative data from patient records.

RESULTS

Nine wrists were included in the study. The average age at the time of surgery was 13.2 years, and the average follow-up period was five years. Extension and ulnar abduction showed a slight decrease from preoperative to follow-up, while flexion improved minimally, and radial abduction and forearm rotation showed noticeable improvement. The visual analogue scale score for pain at rest increased from preoperative 0.25 points to 1.88 points at follow-up. Under load, the average pain score increased from 2.00 to 4.25 points. The mean DASH score increased from 6.04 points before the surgical procedure to 12.20 points at follow-up. The average values of two out of the five measured McCarroll parameters increased, the increase being statistically significant for lunate subsidence. A follow-up procedure was required in one wrist.

CONCLUSION

In our cohort, the progression of Madelung's deformity was only partially halted by physiolysis with resection of the Vickers ligament, and a significant increase in pain symptoms during the study period could not be avoided. Therefore, this procedure should be used cautiously in skeletally immature patients.

Results of primary radial corrective osteotomy in Madelung's deformity

INTRODUCTION

The purpose of this study was the evaluation of surgical outcomes in a series of wrists with Madelung's deformity treated with radial corrective osteotomy. We hypothesize that this surgical technique is a suitable and safe way of treatment.

MATERIALS AND METHODS

A retrospective review of patients with Madelung's deformity treated with radial corrective osteotomy between January 2001 and June 2017 at a single large department of hand surgery in Germany was performed. Patients who met the inclusion criteria were invited for follow-up and outcome variables including pain, range of motion, patient-rated outcome measures, and radiographic measurements were obtained for comparison with preoperative data collected from the patients' medical records.

RESULTS

14 wrists were included. The average age at the time of surgery was 21.9 years, and the average follow-up was 7.2 years. The average visual analog pain scale at rest decreased from preoperative 2.6 points to postoperative 0.7 points. Under strain, the average VAS declined from 7.4 to 4.9 points. The mean DASH Score decreased from 42.9 before surgery to 22.0 points after surgery. Range of motion improved slightly in five out of six directions of motion, with the greatest increase seen in average supination from preoperative 68.5° to postoperative 82.0°. Averages of all five measured McCarroll's parameters and ulnar variance decreased, as expected from corrective surgery. Four wrists (26.8%) needed subsequent procedures.

CONCLUSION

Radial corrective osteotomy was a suitable treatment of Madelung's deformity in our collective, although surgical outcomes are not yet fully satisfying.

Medium to long term functional and radiographic outcomes in patients with Madelung's deformity treated by isolated or combined radioulnar osteotomy

INTRODUCTION

Madelung's deformity is a rare congenital condition of the wrist that can cause pain, aesthetic concerns, reduced range of motion and grip strength. Currently, there is no consensus on the optimal age for surgery or whether operative procedures can be isolated or combined depending on the extent of the deformity. The main objective of our study was to analyze the postoperative functional clinical results at a minimum of 3-years follow-up in patients operated on for Madelung's deformity. The secondary objectives were (1) comparison of preoperative and postoperative radiographic parameters, and (2) to assess whether certain preoperative radiographic parameters influence the choice of surgical procedure.

HYPOTHESIS

The surgery offered at our center achieves clinical and radiological result necessary for long-term activities of daily living, and varies according to the severity of the distal radial deformity.

PATIENTS AND METHODS

We carried out a retrospective observational monocentric study including patients operated on between 2004 and 2016. Clinical (VAS, mobility), functional (PRWE score), and radiographic assessments were performed before and after the last follow-up.

RESULTS

The study included 11 patients (12 wrists) with a mean age of 17±7.3 years and a mean follow-up of 8.1 years (4-12.3). The mean VAS was 2.3 (0-6) and the mean PRWE score was 37 (0-108). The mean flexion-extension arc was 134° and that of pronation and supination was 142°. The mean grip strength was 25.8±11.8kg. Four out of 6 radiographic criteria were significantly improved. An isolated radial osteotomy or combined radioulnar osteotomy was performed when the sagittal radial tilt was greater than 30° and protrusion of the lunate greater than 5mm, otherwise below these values, an isolated ulnar osteotomy was performed.

DISCUSSION

Our center offers surgical management of Madelung's deformity by osteotomy which improves the majority of postoperative radiographic parameters and gives satisfactory clinical and radiographic results after a mean follow-up of 8.1 years. The surgery is influenced by the severity of the distal radial deformity, including protrusion of the lunate and sagittal radial tilt.

Evaluation of a Grip-Strengthening Algorithm for the Initial Treatment of Chronic, Nonspecific Wrist Pain in Adolescents

Purpose

Chronic, nonspecific wrist pain in adolescents can be challenging to assess and treat. We hypothesized that an algorithmic approach beginning with grip strengthening can alleviate pain, improve function, and identify patients in need of further intervention.

Methods

We retrospectively reviewed the results of a grip-strengthening protocol for adolescents with chronic, nonspecific wrist pain. Before and after treatment, grip strength was measured using handheld dynamometry, and patient-reported pain and function were measured using the adolescent self-reported Pediatric Outcomes Data Collection Instrument’s (PODCI’s) Pain/Comfort and Upper Extremity Function domains (PODCI/pain and PODCI/UE, respectively).

Results

Thirty-two patients (28 female, 4 male) were included, with a mean age of 14 years (range, 10–18 years) and the dominant hand affected in 19, nondominant hand in 9, and bilateral impacts in 4. The mean symptom duration prior to presentation was 9 months (range, 1–63 months); 17 patients had undergone prior immobilization and 5 prior occupational/physical therapy. Grip-strengthening treatment, lasting a mean of 40 days (range, 21–82 days) with a median of 4 therapy visits (range, 2–6), was associated with significantly improved grip strength (mean, 32–48 lbs), PODCI/pain scores (mean, 49.0–78.2 points), and PODCI/UE scores (mean, 78.2–91.2 points). Improvements in grip strength correlated with improvements in PODCI/pain and PODCI/UE scores (r = 0.64 and 0.70, respectively). Eight patients (25%) had either no or incomplete pain relief: 5 underwent successful further intervention (2 ganglion cyst excisions, 1 triangular fibrocartilage complex repair, 1 arthroscopic debridement, 1 steroid injection), 2 received ongoing pain management for generalized pain syndromes, and 1 was lost to further follow-up. No pretreatment variables were identified that predicted failure.

Conclusions

Grip strengthening relieves pain and improves function in the majority of adolescents with chronic, nonspecific wrist pain. Systematic use of this protocol helps to identify patients who require further intervention.

Madelung-type deformity in a female individual from the Merovingian Period in Central Germany: A rare finding or a rare disease?

OBJECTIVE

This paper presents a probable case of Madelung-type deformity of the right lower arm in an individual from the Merovingian burial ground (7th and 8 th century CE) from Gotha-Boilstädt (Germany).

MATERIALS

A female individual with an age-at-death of 40-50 years was investigated.

METHODS

Macroscopic, osteometric and radiographic analyses were performed using standard methods.

RESULTS

The individual exhibits an unusual case of dysmelia of the right upper extremity. The shoulder and upper arm displayed gracile muscle attachment marks and less robustness compared to the left side. The ulna was shortened and distorted and the radius was severely deformed.

CONCLUSIONS

The results indicate that the individual might have been affected by a unilateral Madelung-type deformity. The severity of this case is greater than that reported in the clinical literature.

SIGNIFICANCE

This study places an ancient rare disease into archaeological and paleopathological contexts, allowing for the evaluation of the term "ancient rare disease." It also highlights the importance of reporting rigorously diagnosed cases in order to raise our level of awareness of the incidence and course of this rare condition in the past.

LIMITATIONS

The diagnosis cannot be stated with certainty, and only a handful of possible diagnoses can be offered. Congenital and acquired etiologies must be considered, especially when compared with clinical cases where severity of conditions may be modified by medical intervention.

SUGGESTIONS FOR FURTHER RESEARCH

Genetic analysis might be helpful in the determination of the etiology of the observed Madelung-type deformity.

Madelung's deformity in children: Clinical and radiological results from a French national multicentre retrospective study

INTRODUCTION

Madelung's deformity is rare. Treatment often consists in radial or ulnar osteotomy, Vickers' ligament resection or ulnar epiphysiodesis. The present multicenter retrospective study reports clinical and radiographic results in various surgeries. The study hypothesis was that early surgery improves outcome.

MATERIAL AND METHOD

Files were analyzed for 36 children (47 wrists) operated on between 1998 and 2015. Mean age at diagnosis was 12 years (range, 6-15 years). Mean follow-up was 7.2 years (range, 2-17.4 years). Two age groups were distinguished: 6-11 and 12-17 years. Endpoints were esthetic, functional (Mayo Wrist Score: MWS) and radiographic [lunate fossa angle (LFA), radial height (RH), lunatum cover rate (LCR), ulnar head translation (UHT), lunatum ascension (LA)]. Techniques mainly comprised distal radius osteotomy (DRO) with ulnar shortening osteotomy (USO), and Vickers' ligament resection (VR), either isolated or associated to osteotomy.

RESULTS

Age at surgery guided choice of technique, but did not impact results. VR gave better functional results when performed in young children; it was mainly performed in the 6-11 years age group, providing very satisfactory results (7 out of 8 wrists) with excellent function (7 out of 8), without improving radiographic parameters; in the 12-17 years age group, even when esthetic results were excellent, functional results were only good-to-acceptable (3 out of 5 wrists) and 1 result was poor. DRO+USO was mainly performed in the 12-17 years age group, with very satisfactory or satisfactory results (8 out of 10 wrists) and excellent function (6 out of 10). DRO+USO appeared to be an option of choice, significantly improving radiographic parameters and correcting the deformity (24.5° improvement in LFA (p=0.0033) and 36.2% improvement in LCR (p=0.0103)). DRO+USO+VR was mainly implemented in the 12-17 years age group, with very satisfactory results (3 out of 4 wrists) and excellent-to-good MWS in most cases (3 out of 4), but without significant radiographic improvement.

DISCUSSION

Esthetic and functional results were comparable regardless of age, except for VR, which gave better functional results in the 6-11 years age group, but without significant difference.

CONCLUSION

The present study showed that, regardless of children's age, surgery provided esthetic, functional and radiographic benefit, although no decision-tree could be drawn up.

Long-term Outcomes Following Vickers Ligament Release and Growth Modulation for the Treatment of Madelung Deformity

BACKGROUND

Madelung deformity arises from a partial distal radial growth disturbance in combination with an abnormal hypertrophic ligament spanning the volar radius and carpus, termed, the Vickers ligament. The purpose of this study is to report long-term clinical and radiographic outcomes following Vickers ligament release and distal radial physiolysis in a population of skeletally immature patients with symptomatic Madelung deformity.

METHODS

Medical records were retrospectively reviewed of patients with Madelung deformity surgically treated between 1994 and 2005. All eligible patients who underwent a Vickers ligament release and distal radial physiolysis were contacted and invited to return to the clinic for follow-up.

RESULTS

Six patients (8 wrists) with Madelung deformity underwent Vickers ligament release and distal radial physiolysis. All were white females with a mean age at initial presentation of 11.4 years (10 to 12.8 y). Mean age at the time of initial surgery was 12.0 years (10.0 to 14.5 y). The median follow-up time was 10.6 years (5.8 to 21.9 y) and the average age at last follow-up was 23.1 years (17.5 to 32.2 y). Pain alone or in combination with concerns for deformity was the chief complaint in 6 of 8 of the wrists. At 1 year of clinical follow-up, 7 of 8 wrists were reported to be pain-free, and 6 of the 8 were noted to be completely pain-free at last follow-up. Motion in flexion, extension, pronation, supination, radial, or ulnar deviation was similar between the preoperative status and long-term follow-up. The average preoperative ulnar tilt was 35.1 degrees (SD: 8.5 degrees), average preoperative lunate subsidence was 1.9 degrees (SD: 1.8 degrees), and average preoperative palmar carpal displacement was 21.9 degrees (SD: 2.9 degrees). At the final follow-up, there was a large progression in lunate subsidence, but minimal change in ulnar tilt and palmar carpal displacement. At last clinical follow-up, 2 of the 6 patients had undergone a subsequent procedure including 1 radial dome osteotomy and 1 ulnar shortening osteotomy.

CONCLUSION

In the skeletally immature patient population with Madelung deformity with growth potential remaining, distal radial physiolysis and Vickers ligament release is associated with relief of pain, preservation of motion, and, a reasonable rate of reoperation.

TYPE OF STUDY

This was a therapeutic study.

Radiotriquetral Ligament in Madelung's Deformity Associated with Leri-Weill's Dyschondrosteosis

Madelung's deformity (MD) is frequently associated with Leri-Weill's dyschondrosteosis (LWD) even if the primary isolated form (PI-MD) is much more common.

Recent studies pointed out how two abnormal ligaments, the Vickers ligament (VL) and the radiotriquetral ligament (RTL), are defining traits of MD. To date, in PI-MD, both VL and RTL have been reported. In MD associated with LWD (LWD-MD), the VL is also present, but the RTL has never been reported.

We herein report the first case of MD associated with a genetically confirmed LDW with an RTL, detected on MRI.

This report describes the MRI imaging features of MD-LWD, which have not been adequately characterized in previous literature.

Dental and Maxillofacial Signs in Leri-Weill Dyschondrosteosis

One of the most common causes of short stature is a defect of the short stature homeobox-containing (SHOX) gene, which is located in pseudoautosomal region 1 on the distal end of the short arm of chromosomes Xp22.33 and Yp11.32. More than 300 different mutations in the SHOX gene responsible for short stature syndrome have been described. The phenotypic expression of SHOX haploinsufficiency is remarkably varied. The 3 typical clinical presentations, from least to most severe, are idiopathic short stature without skeletal malformations, Leri-Weill dyschondrosteosis (LWD), and Langer mesomelic dysplasia, which is believed to represent the homozygous form of LWD. Despite a higher prevalence in women, suggesting the potentiating action of high estrogen levels on the effects of SHOX deficiency, the syndrome was initially believed to have an autosomal pattern of inheritance. In reality, heterozygous SHOX mutations can be transferred from the Y to the X chromosome and vice versa. This phenomenon is called "the jumping SHOX gene" and corresponds to a pseudoautosomal dominant inheritance. LWD is characterized by mesomelic short stature and Madelung deformity defined by an upward and medial displacement of the radial joint surface, which restricts range of motion. Less specific dysmorphic signs associated with LWD, such as short hands and feet, scoliosis, or muscular hypertrophy, have been described. When reviewing the dental and maxillofacial signs, only limited and summary data (micrognathia and high arched palate) have been published in the literature. This report presents a case of LWD that highlights many other noteworthy dental and maxillofacial signs that are important to clearly identify and appropriately treat.
