‘It’s A Wonderful Life’ Sequel Could Be Blocked By Paramount

The upcoming sequel to Frank Capra's classic Christmas film It's a Wonderful Life could be blocked by Paramount Pictures, which owns the copyright to the 1946 film.

The studio acquired Spelling Entertainment and its Republic Pictures subsidiary, which owned the rights to the original 1939 story "The Greatest Gift," in 1998.

Paramount said that Hummingbird Productions and Star Partners have not obtained sequel rights to the movie.

"No project relating to 'It's a Wonderful Life' can proceed without a license from Paramount," a Paramount spokesman said. "To date, these individuals have not obtained any of the necessary rights, and we would take all appropriate steps to protect those rights."

The film's producer, Bob Farnsworth, told Variety that the producers have a "clear" claim to the sequel rights.

"We have spent a lot of time, money and research that leads us to believe that we are clear on any infractions of the copyright," Farnsworth said. "If anyone feels that have a legal claim, we will be happy to talk with them. I believe that whatever resolution needs to be made will be made amicably, in the positive spirit of the project."

The sequel, called It's a Wonderful Life: The Rest of the Story, will focus on the unlikeable grandson of George Bailey (who is also named George Bailey). Karolyn Grimes, who played George's daughter, Zuzu, in the original, has agreed to play an angel who shows George what the world would be like if he had never been born.

"The new film will retain the feeling of the original, and it simply must be shared. I've probably read close to 20 scripts over the years suggesting a sequel to 'It's a Wonderful Life,' but none of them were any good," Grimes said. "The script by Bob Farnsworth and Martha Bolton was wonderful, and I wanted to be involved with his version of the film immediately."

2. Definition/Description

Leg length discrepancy, or anisomelia, is defined as a condition in which the paired lower extremity limbs have a noticeably unequal length.
Classification of leg length discrepancy (LLD):
Structural (SLLD) or anatomical: Differences in leg length resulting from inequalities in bony structure.
Functional (FLLD) or apparent: Unilateral asymmetry of the lower extremity without any concomitant shortening of the osseous components of the lower limb.
3 Epidemiology/Etiology

Prevalence of LLD is a topic in recent literature that evokes heavy discussion. Little agreement exists regarding the degree of LLD that is clinically significant to treat, with values ranging from 3 to 60 mm.
Some authors have tried to determine a significant LDD by quantification, others by a significant discrepancy in functional outcomes. This values are found in the review by Burke Gurney 2002 Gait and posture.
Prevalence rates for leg length difference often lack crucial information regarding demographics, examiner experience, methods to recruit patients, methods used to detect leg inequality and yet it is often cited and used by other authors.

Etiological factors :
" Idiopatic developmental abnormalities
" Fracture
" Trauma to the epiphyseal endplate prior to skeletal maturity
" Degenerative disorders
" Legg-calv?(C)- Perthes disease
" Cancer or neoplastic changes
" Infections
" Functional:
o Shortening of soft tissues
o Joint contractures
o Ligamentous laxity
o Axial malalignments
o Foot biomechanics (such as excessive ankle pronation)

4. Characteristics/Clinical Presentation

In concordance with the classification of LLD, the characteristics can be divided into two categories:
Functional limitations, including gait and balance problems :
The role of LLD on standing posture/ balance: Check for specific compensation used by the patient to level out the difference in height.:
- Pronation in the ankle of the longer leg
- Supination or plantar flexion in the shorter leg
- Knee and hip extention of the shorter or flexion in the longer leg
- If the leg is left uncompensated, the anterior and posterior iliac spine on the side of the short leg can be lower which may result in a sacral base unlevelling and/or scoliosis.
- Increased muscle activity in several muscle groups
The role of LLD on walking:
- Gait asymmetries throughout the kinetic chain
- Increased vertical displacement of center of mass resulting in increased energy consumption.
o Compensatory mechanisms for this: calcaneal eversion, knee extension, toe walking, circumduction, hip or knee flexion (steppage gait)
- Decreased stance time and stride length in the shorter leg
- Decreased walking velocity, increased walking cadence
The role of LLD on running: Biomachanics in running is different from walking, as are the effect of LLD. In running, the vertical oscillation is greater and there is no double support so weight is not shared between legs. The stance phase is only 30% in running wheras 60% in walking. This results in stress on the lower extremity that is three times that of walking. Evidence is conflicting about the effect of running but it is suggested that the effect is also augmented threefold.

Associated musculoskeletal disorders :
Low back pain: Literature is very ambiguous. LLD appears to affect the lumbar spine, at least in part, by creating a lumbar scoliosis. It has been shown that LLD leads to pelvic obliquity on the frontal plane inducing a scoliosis. (Gurney) .
Lumbosacral facet joint angles appear to be smaller on the short side, it is hypothesized that asymmetry of joint angles predispose patients to osteoarthritic changes in lumbosacral joints. (Giles)
Further research will conclude if LLD is merely associated or a objective causal factor in LBP, literature at hands is contradicting and non conclusive.
Hip pain: A longer leg might be a predisposing factor in Osteoarthritis (OA). With length increasing, femoral head contact/ weight bearing area is decreasing. (+10mm- 5%/ +50mm - 25,1%). Combined with an increased tone in hip abductors caused by elongated distance between origin and insertion and an increased GRF puts the longer leg at risk.
Stress Fractures: Greater incidence of stress fractures in the tibia, metatarsals and femur of the longer leg appears consistent with the greater forces emitted trough the longer leg described under hip pain.
Other: There seems to be an association with trochanteric bursitis, patellar apicitis, patellar joint incongruencies and myofacial pain syndrome of the peroneus longus

There are three types1,2 of limb length discrepancy inequality (LLI) also called leg length discrepancy.

- Anatomical1,2; structural limb length inequality. It"s a physical (osseous) shortening of one lower limb between the trochanter femoral major and the ankle mortise.

- Functional1,2; non-structural shortening. It is a unilateral asymmetry of the lower extremity without any shortening of the osseous components of the lower limb.*

- Environmental1; it"s only significant for a small number of high-level athletes or a specialized workforce population. An example: accumulation of forces during running when a runner consistently trains on 1 side of a crowned road.
" Environmental LLI can easily be solved by asking the runner to run in the opposite side then he usually runs. Environmental LLI is often considered as a functional LLI.
A functional inequality may occur at any level of the lower extremity from the most superior aspect of the ilium to the most inferior aspect of the foot. Different causes may lead to a functional inequality: foot mechanics, adaptive shortening of soft tissues, joint contractures, ligamentous laxity and axial malalignments

6. Examination and outcome measures

The most accurate method to identify leg (limb) length inequality (discrepancy) is through radiography. It"s also the best way to differentiate an anatomical from a functional limb length inequality.

- Radiography1,2:
A single exposure of the standing subject, imaging the entire lower extremity. Limitations are an inherent inaccuracy in patients with hip or knee flexion contracture and the technique is subject to a magnification error.
Computed Tomography (CT-scan)1: It has no greater accuracy compared to the standard radiography. The increased cost for CT-scan may not be justified, unless a contracture of the knee or hip has been identified or radiation exposure must be minimized.

However, radiography has to be performed by a specialist, takes more time and is costly. It should only be used when accuracy is critical. Therefore two general clinical methods were developed for assessing LLI.

- Direct methods1,2: they involve measuring limb length with a tape measure between 2 defined points, in stand. Two common points are the anterior iliac spine and the medial malleolus or the anterior inferior iliac spine and lateral malleolus.
Be careful, however, because there is a great deal of criticism and debate surrounds the accuracy of tape measure methods. If you choose for this method, keep following topics and possible errors in mind:
" Always use the mean of at least 2 or 3 measures
" If possible, compare measures between 2 or more clinicians
" Iliac asymmetries may mask or accentuate a limb length inequality
" Unilateral deviations in the long axis of the lower limb (eg. Genu varum,") may mask or accentuate a limb length inequality
" Asymmetrical position of the umbilicus
" Joint contractures

- Indirect methods1,2: Palpation of bony landmarks, most commonly the iliac crests or anterior iliac spines, in stand. These methods consist in detecting if bony landmarks are at (horizontal) level or if limb length inequality is present.
Palpation and visual estimation of the iliac crest (or SIAS) in combination with the use of blocks or book pages of known thickness under the shorter limb to adjust the level of the iliac crests (or SIAS) appears to be the best (most accurate and precise) clinical method to asses limb inequality.

You should keep in mind that asymmetric pelvic rotations in planes other than the frontal plane may be associated with limb length inequality. A review of the literature suggest, therefore, that the greater trochanter major and as many pelvic landmarks should be palpated and compared (left trochanter with right trochanter) when the block correction method is used.

Exact procedure of the indirect measurement method: the use of blocks :
Patient is standing with feet 10 cm apart, knees extended and equal weight on both feet.
The clinician places his/her hands on a bilateral anatomical structure: spina iliaca posterior superior, spina iliaca anterior superior or crista iliaca left and right.
Now the clinician visually assesses if there is a length inequality, and if so, places a wooden board of 0,5 cm under the foot of the shorter side.
Keep placing thicker planks under the shorter side until equal length is reached, the thickness of the plank is equal to the leg length difference.
Although Reliability is highly dependent on the accurate measurements of the clinician, this method has shown excellent results in inter- examinator results between highly trained clinicians and medicine students . Confounding variables reported by literature are: pelvical asymmetry, incorrect positioning of feet, obesity, joint contractures, scoliosis and inaccurate measurement.
Leg length discrepancy after Total Hip Arthroplasty (THA)
Clinical signs: Patients can be categorized into three types according to the presentation of symptoms: 1) Most commonly, patients with pain from the resultant imbalance in muscle force around the hip and knee, as well as around the spine. 2) Pain and fatigue from the longer leg"s Quadriceps and hamstring muscles (flexed knee syndrome). Patients flex their knee during gait to maintain level pelvis. 3) Instability or dislocation as result of component orientation, the pain is often a result of hip and periarticular muscle fatigue from preventing subluxations.
Correctable cause after THA: initial postoperative apparent LLD. The initial postoperative LLD can be described as periarticular muscle spasm, lumbosacral scoliosis, and pelvic obliquity. They can each produce this early postoperative LLD. The physical result is a tilted pelvis relative to the floor, with the surgical hemipelvis pushed inferiorly and the contralateral hemipelvis pulled superiorly, giving an apparent LLD despite equal lengths from the anterior superior iliac spines to medial malleoli. The mainstay of treatment for this problem is patient education, reassurance, physical therapy muscle techniques, and possibly a temporary shoe lift. The patient should be reassured that most cases resolve within 6 months from surgery.

7. Medical Management

Two factors dictate if intervention is needed or not: the magnitude of the inequality and whether or not the patient is symptomatic.
Reid and Smith [15] suggest dividing limb length inequality intro three categories: mild (0-30 mm), moderate (30-60mm) and sever (>60mm). They suggest that mild cases shouldn"t be treated surgically, except if patient is symptomatic then a non-surgical intervention can be applied. Moderate cases should be dealt case by case and may be dealt with surgically intervention. Sever cases should be corrected surgically.

- Non-surgical intervention :
Use of shoe lifts, up to 20mm. Further corrections should be done on the sole of the shoe or making adapted shoes for the patient.
- Surgical intervention:
" Consist in stopping the bone growth (in the longest leg) in adolescents and children.
" Sometimes, in patients with skeletal maturity, limb shortening by bone resection procedures is sometimes performed.
" Limb lengthening is generally reserved for LLI greater than 40-50mm. It involves corical osteotomy followed by the extremity being fitted with an external fixation device that applies continuous longitudinal distraction across the osteotomy site.

8. Physical Therapy Management

The non-surgical intervention is mainly usedfor the functional and environmental types of leg length discrepancies. It is also applied to the mild category of limb length inequality.

Non-surgical intervention consists of stretching the muscles of the lower extremity. This is individually different, whereby the M. Tensor Fascia latae, the adductors, the hamstring muscles, M. piriformis and M. Iliopsoas are stretched.

In this non-surgical intervention belongs also the use of shoe lifts. These shoe lifts consists of either a shoe insert (up to 10-20mm of correction), or building up the sole of the shoe on the shorter leg (up to 30-60mm of correction). This lift therapy should be implemented gradually in small increments.

Several studies have examined the treatment of low back pain patients with LLD with shoe lifts. Gofton obtained good results: the patients experienced major or complete pain relief that lasted upon follow-up ranging from 3 to 11 years. Helliwell also observed patients whereby 44% experienced complete pain relief, and 45% had moderate or substantial pain relief. Friberg found that 157 (of 211) patients with LBP, treated with shoe lifts, were symprom-free after a mean follow-up of 18 months.

However, evidence in the literature regarind the use of lift therapy is inconsistent.

LLD and Low Back pain.

Shoe lifts can reduce low back pain, if patients" low back pain is correlated to the LLD. See Differential Diagnosis! Important is to gradually increase the corrective lift, rather than correct a fixed percentage of LLD . Shoe inserts appear to reduce (chronic) low back pain and functional disability in patients with LLDs of 10mm or less. It can be added to the treatment (low back exercises) . The importance of exercises lies in the fact that (one study suggest that:) the quadratus lumborus endurance ipsilateral to the supine short leg has significantly decreased endurance combared to people with no leg-length asymmetry . However, this is only 1 small observational study and further research about changes in muscle endurance and strength in people with LLD is needed.

The PALM (palpation Meter)

The PALM is a reliable and valid instrument for measuring pelvic height difference (PD). It is convenient, cost-effective and is a good alternative to radiographic measurement!

Measurement Procedure:
2 tape strips were placed on the ground, 15cm apart. The tape strips mark the location on the floor were patients have to place their feet. The patients are asked to walk for 10 steps and the align the medial borders of their feet with outside of the tape strips. Patients have to stand fully erected (no knee or hip or spine bending). The PALM is placed on the most superior aspect of the iliac crest. The distance between caliper heads are measured to the nearest mm and the angle of inclination to the nearest half degree. The inclinometer ball is designed to move towards the side of the shorter limb.
