[Treatment of Dupuytren's contracture (author's transl)].

Surgical treatment of Dupuytren's contracture improves function but cannot remove the cause of the disease. Strict selection of cases, knowledge of the anatomy, the use of incisions appropriate to the local alterations, an atraumatic operative technique, and careful aftercare are essential for positive results. The literature cites success rates of between 60 and 85 percent. Recurrences cannot always be avoided but the frequency can be reduced by meticulous removal of all diseased and normal connective tissue in this area.

Defective collagen fibril formation and mineralization in osteogenesis imperfecta with congenital joint contractures (Bruck syndrome).

We describe a male patient with osteogenesis imperfecta (OI) who was born with contractures of the knee, elbow and ankle joints. During the first 4 years he suffered from recurrent fractures. He has white sclerae, mild dentinogenesis imperfecta, multiple wormian bones, severe scoliosis and short stature. Morphological analysis of cortical bone revealed typical characteristics of OI including varying width of the osteoid, swollen mitochondria and a dilated endoplasmic reticulum of the osteoblasts. Collagen fibrils of the osteoid had a varying diameter, a feature not found in typical OI patients. Analysis of compact bone showed that the size of apatite crystals and the extractability of collagen with pepsin were markedly elevated compared to controls and other OI type III and IV patients. Lysyl hydroxylation of collagen from the organic bone matrix and the electrophoretic mobility of collagen alpha 1(I)- and alpha 2(I)-chains were normal. Our results provide evidence that this patient belongs to a subtype of OI. The biochemical studies indicate that the underlying defect involves defective fibril-formation of collagen type I leading to an altered mineralization of bone.

[Acute intermittent porphyria with transient paresis and contracture. Evidence for initial myopathic dysfunction?].

A 70-year old man with acute intermittent porphyria had acute transient bibrachial paresis with moderate contracture of the involved muscles, which showed electrical silence in a conventional electromyographic investigation with surface electrodes placed over the contracted muscle belly (filter: 20 Hz-2 Hz, amplifier 50 microV). Slow finger movements were still possible and showed typical muscle-action potentials. This electroclinical correlation points to myopathic localized dysfunction, perhaps similar to rare case reports with patients having metabolic myopathy of McArdle's type.

[Nonoperative treatment of ischemic contractures of forearm and hand].

The acute compartment syndrome of the forearm and hand leads to severe muscle necrosis and nerve damage if the diagnosis is not recognized. The resulting ischemic contractures and paralyses require a distinctive regime of therapy. Therefore,physiotherapy and occupational therapy are of main importance. In mild cases exclusively nonoperative treatment is possible. The goal is to exercise the function of the remaining muscles, mobilize the joints, and stretch muscle scars. Severe forms need surgery. To reach the best starting point for the operation, extensive preoperative active and passive exercises as well as splint therapy are required. Postoperatively, this regime has to be continued to retain a favorable outcome. The treatment approach is demonstrated with a case report.

Iliac hyperdense line: a new radiographic sign of gluteal muscle contracture.

BACKGROUND: A hyperdense line on the ilium that runs roughly parallel to the sacroiliac joint (we called it "iliac hyperdense line sign") was frequently observed on pelvic radiographs of patients with gluteal muscle contracture (GMC). A literature search revealed no description of this sign. OBJECTIVE: To determine the relationship between the iliac hyperdense line sign and GMC and to explore how this sign is formed. MATERIALS AND METHODS: Pelvic plain films of 103 cases of GMC and those of 200 control individuals were reviewed for the presence or absence of the iliac hyperdense line sign. Pelvic CT scans in 8 of 103 cases and 13 of 200 controls were analyzed with relation to the plain films. RESULTS: The iliac hyperdense line sign was visualized in 85 of 103 (82.5%) cases of GMC and none of the 200 controls. In the GMC group, pelvic CT scans showed a deformity of the posterior ilium. The lateral cortex of the posterior ilium took on a partly or completely anteroposterior course, while in the control group the course appeared as an oblique orientation from posteromedial to anterolateral. CONCLUSION: The iliac hyperdense line on pelvic plain film can be used as a radiographic sign to suggest a diagnosis of GMC. This sign might be a result of the long and persistent pulling effect of the contracted gluteus maximus muscle, which deforms the lateral cortex of the posterior ilium from an oblique course to an anteroposterior course tangential to the X-ray beam.

Osteogenesis imperfecta with joint contractures: bruck syndrome.

We describe an Egyptian boy with osteogenesis imperfecta who was born with thumb contractures and bilateral antecubital pterygia. He was seen at 16 months of age with femur and tibial fractures, thoracic vertebral compression fractures, scoliosis and Wormian bones. The findings are consistent with a diagnosis of Bruck syndrome.

The use of combined lateral and medial releases in the treatment of post-traumatic contracture of the elbow.

Elbow stiffness is a common disorder, which restricts daily activities. Between 30 degrees and 130 degrees of elbow movement is usually enough to perform most daily activities. However, a 10 degrees to 15 degrees loss of elbow extension may be a problem when the patient is an athlete. From 1996 to 2004, 20 elbows of 20 patients (who were available for follow-up examination) were treated by lateral and medial release at Kocaeli University, for post-traumatic elbow contracture. Preoperative and the postoperative 12-month follow-up measurements were performed. The mean preoperative arc of motion was 35 degrees and this value improved to 86.2 degrees . The maximum improvement at the arc of motion was 105 degrees . In an effort to understand the pathophysiology of the condition, surgical approaches may be used safely. The purpose of this study was to assess the functional outcome of the elbow joint after using a combination of lateral and medial approaches to treat elbow stiffness.

A different strategy in the surgical treatment of capsular contracture: leave capsule intact.

The authors present their experience with the surgical treatment of capsular contracture to achieve better results in a safe, predictable, and practical way, and discuss the possible treatment modalities. They simply advise leaving the capsule intact, even if it is calcified, and create another pocket, rarely in the front or, more typically, at the back of the capsule. If the breast tissue is also ptotic, a mastopexy procedure may be added to the procedure, in addition to augmentation, with a rather small prosthesis placed in the new pocket or, occasionally, in the old one. External, forceable massage is not advisable to treat the capsule. Open capsulotomy and/or partial capsulectomy can be applied to release the capsule. However, it is not advisable since recurrence is usually inevitable. The purpose of this paper is to present a series of surgical procedures to avoid the problems created by the capsule and present different cases with good results.

Electrostimulation: uses and applications for periprosthetic capsular contracture: experimental model.

BACKGROUND: Studies have documented an increase in collagen production and acceleration of the scarring process when galvanic electrostimulation of less than 300 mV is used, but the effects of electrostimulation with characteristics different from those usually studied are unknown. METHODS: Electrostimulators were designed and manufactured specifically for the study. A total of 40 rats were divided into 10 groups, with 4 randomly selected rats in each group. Five groups received smooth implants, and the remaining five groups received textured implants. The first group was designated as the control group, and the remaining four groups received electrostimulation in differing amounts from the 3rd to the 15th postoperative day. RESULTS: The type of implant used was not a determining factor in the degree of capsular contracture encountered. In the groups that received less than 300 mV, showed greater capsule thickness than the control group. The group that received 600 mV, had a thinner periprosthetic capsule than the control group and all the other groups. All the results were statistically significant. CONCLUSIONS: Electrostimulation using direct galvanic current with reversal of polarity on postoperative day 3 at intensities of 600 mV inhibits the process of periprosthetic capsular formation in rats.

Diabetes with hyperlipidemia: a risk factor for developing joint contractures secondary to immobility in rat knee joints?

Several studies have reported that diabetes may cause limited joint motion and often combines with hyperlipidemia (HL). This study clarifies that joint contracture can be produced by diabetes, HL, or both. The experimental animal model, a rat with diabetes and HL, was developed by streptozosin injection and addition of 1% cholesterol to the food. One hindlimb each from the diabetes group, the HL group, the combined diabetes/HL group, and the control group was immobilized for 2, 3, or 4 weeks in the Phase I study. Diabetes/HL rats were used 4 weeks after immobilization in a Phase II study. Joint motion, elasticity of the knee joint capsule, and contractile function of the gastrocnemius muscle were measured. Gastrocnemius muscle was observed histologically by H&E and ATPase staining. Limited joint mobility was observed 4 weeks after immobilization only in the diabetes/HL group. The intraarticular pressure from the saline injection was lower, and the contractile function of the gastrocnemius muscle decreased in this group. Atrophy of type II fiber was observed in the gastrocnemius muscle. This restriction of joint mobility may depend on skeletal muscle degeneration around the joint rather than on an intraarticular lesion.

Clinical features of scleroderma patients with contracture of phalanges.

Contracture of phalanges (CP) is a frequent complication of patients with systemic sclerosis (SSc). The objective of this study was to examine the prevalance of CP in patients with SSc and investigate the clinical and laboratory features of SSc patients with CP. Three hundred and fifty patients with SSc were examined. CP was found in 164 of the 350 patients (47%) with SSc. The prevalence of oesophageal involvement, pulmonary fibrosis or heart involvement was significantly greater in the patients with CP than that in those without CP. Our study suggested that the presence of CP may be a marker of oesophageal involvement, pulmonary fibrosis and heart involvement.

Myogenic knee contracture from acute pelvic venous thrombosis.

A unique case of knee extension contracture resulting from acute pelvic venous thrombosis is presented. Magnetic resonance imaging/angiography and electrodiagnosis aided in understanding the pathogenesis and hence in designing the treatment. Neuropathies contributed to the severity of the problem. Physical treatment to ease the edema improved knee joint range of motion but did not fully restore knee flexion.

Fasciotomy and Z-plasty in the management of Dupuytren's contracture.

The technique of fasciotomy and Z-plasty for the management of Dupuytren's contracture is described. The results of its use in a series of nine patients is presented. It is suggested that this method is applicable to the patient whose disease is confined to a single ray in the palm. None of the patients studied required re-operation during the period of follow-up which ranged from 2 years 4 months to 5 years 6 months.

Multiple seagull flaps for digital contractures in electrical burns.

Following legislation in the early 1970s, electrical bar fire burns are much less common in the UK than 20 years ago. However, their long-term effects are still encountered as microdactyly, syndactyly and digital flexion contractures. A case is described in which multiple seagull flaps were used as a single stage procedure to achieve sustained improvement in function in a severely affected hand, 10 years after injury, without prolonged postoperative daytime splintage.
