A qualitative assessment of shoulder girdle elevation during the upper limb tension test 1.

The 'feel through range' and the 'end-feel' of the elbow extension, and the elevation of the shoulder girdle during the upper limb tension test for the median nerve are considered important in clinical decision making. As no objective measurements have been published regarding these parameters, a special device was designed in order to obtain objective information on the force by which the shoulder girdle is elevated during the test. The purpose of this technical note is to describe the technical aspects of the device and its practical application. In a pilot study, five asymptomatic subjects have been assessed. The relationship between the elevation of the shoulder girdle and the range of elbow extension has been analysed. The data of five subjects and representative curves of one subject are presented. All five subjects demonstrate a considerable increase in force elevating the shoulder girdle. The results show that the device can be used to measure the force by which the shoulder girdle is elevated throughout the test. Although the number of subjects and the number of repetitions is limited, the data suggest that the method is accurate and that the phenomenon of shoulder girdle elevation during the upper limb tension test in asymptomatic subjects is consistent.

Shoulder girdle elevation during neurodynamic testing: an assessable sign?

One of the signs advocated for monitoring during neurodynamic testing in the assessment of patients with upper quadrant disorders, is the response of the shoulder girdle. It is stated that a protective rising of the shoulder girdle is present when patients with neurogenic disorders are assessed and that the elevation is absent in asymptomatic subjects. As sensory responses are elicited in the majority of asymptomatic subjects and as the range of motion (ROM) is often limited during neurodynamic testing, it is questionable whether the elevation of the shoulder girdle would be absent in asymptomatic subjects. The aim of this study was to measure the shoulder girdle elevation force during five variants of the neural tissue provocation test for the median nerve. Thirty-five asymptomatic male subjects were assessed. A load cell was used to measure the amount of shoulder girdle elevation force and two electrogoniometers were used to measure the ROM at the elbow and wrist. When the ROM at the end of the test was restricted, a gradual increase in shoulder girdle elevation force could be observed throughout the test. Compared to the initial force at the start of the test, all variants resulted in a significant increase in force. It is concluded that a gradual increase in shoulder girdle elevation force should not be regarded as an abnormal sign in the interpretation of neurodynamic tests.

Silicones in the rehabilitation of burns: a review and overview.

This article gives an overview of the use of silicones in the treatment and prevention of hypertrophic (burn related) scars. Of all non-invasive treatment modalities the use of continuous pressure and occlusive contact media, e.g. silicones, seem to be generally accepted as the only ones that are able to manage hypertrophic scarring without significant side-effects. A summary of the current opinions of the assumed working mechanisms of pressure as well as silicones is given. The use of silicones, either alone or in combination with pressure, is discussed. The recent development of custom made silicone devices has led to combinations of both modalities. Some of these, including the inflatable silicone insert systems (ISIS), are shown and discussed.

Unstable femoral neck fractures in young adults: treatment with the AO 130-degree blade plate.

OBJECTIVE: To evaluate the clinical outcome of the treatment of unstable femoral neck fractures using the AO 130-degree blade plate. DESIGN: Between 1980 and 1994, thirty-four consecutive patients younger than age fifty years with an unstable intracapsular femoral neck fracture (Garden Types III-IV) were treated with internal fixation. SETTING: University Hospital Gasthuisberg, Leuven, Belgium. INTERVENTION: The AO 130-degree blade plate with an antirotation, 6.5-millimeter, partially threaded cancellous lag screw was used. RESULTS: Nineteen (63.3 percent) patients had an excellent result, seven (23.3 percent) had a good result, three (10 percent) had a fair result, and one (3.3 percent) had a poor result. Delayed union was observed in one case, and avascular necrosis was observed in two cases. Two implants perforated the subchondral bone. CONCLUSION: Stable fixation with the AO 130-degree blade plate avoids damage to the adjacent blood supply to the femoral head and appears to guarantee a good final outcome of unstable intracapsular femoral neck fractures in young adults.

Pertrochanteric fractures in the elderly: are there indications for primary prosthetic replacement?

During a 10-year period (1978-1988), 565 patients, aged greater than or equal to 70 years, who sustained a fresh pertrochanteric fracture, were treated in the Department of Traumatology at the University Hospitals of Leuven, Belgium. Three hundred eighty-eight fractures were complex and unstable, according to the Evans-Jensen system and the AO system. Special attention was given to the 324 cases of type IC and ID in Evans' system, type A2 in the AO system. The method of treatment changed greatly during the period of study. All patients were followed prospectively during 1 year. Our study showed that for these unstable fractures, fixation with an angled plate or Ender nails should be forsaken. The overall results of the compression hip screw treatment were good (reoperation rate 2%, good functional results in 64%), but as this treatment has a risk for serious collapse and pain in about 80% of all type ID fractures, one could suggest treating these complex multifragment fractures primarily with an endoprosthesis. This treatment need no longer be considered severe intervention, as the danger of mechanical complications is minimal (less than 1%).

Treatment of unstable peritrochanteric fractures in elderly patients with a compression hip screw or with the Vandeputte (VDP) endoprosthesis: a prospective randomized study.

A prospective randomized study was set up, comparing a compression hip screw with the Vandeputte (VDP) endoprosthesis treatment for fresh, unstable peritrochanteric fractures, according to the Evans-Jensen and AO systems. Ninety patients, ages > or = 70 years, 47 of whom were treated with a compression hip screw and 43 with a VDP endoprosthesis, were included. All patients were being followed for 3 months. No difference between the two groups was found for operating time, wound complications, and mortality rate, but there was a higher transfusion need in VDP treatment. Severe fracture redisplacement or total collapse of the fracture occurred in 11 (26%) compression hip screw patients, two of whom had revision surgery. Only one patient needed reintervention after VDP treatment. Functional capacity of preoperative independent patients at hospital discharge did not differ for the two groups. In conclusion, the compression hip screw seemed to be an appropriate implant for most of the peritrochanteric fractures, but for very old patients with advanced osteoporosis, with a complex, unstable peritrochanteric fracture, and who are eligible for early mobilization, primary cemented endoprosthesis might be the best treatment.

Addition of test components during neurodynamic testing: effect on range of motion and sensory responses.

STUDY DESIGN: Single session, repeated-measures design. OBJECTIVES: To analyze the impact of different components of the neural tissue provocation test for the median nerve (NTPT1) on the range of motion (ROM) of the elbow and wrist and the sensory responses elicited by the test. BACKGROUND: The assessment of minor peripheral nerve injuries by neurodynamic tests is becoming more integrated in physical therapy practice. The influence of different test components on the nervous system has been analyzed in numerous in vitro studies, but in vivo studies are still lacking. METHODS AND MEASURES: Five test variations were performed on 35 asymptomatic men (23.5 +/- 2.3 years). Elbow extension was performed (1) without additional components (NTPT1NEUTRAL), (2) with wrist extension (NTPT1WE), (3) with cervical contralateral lateral flexion (NTPT1CLLF), and (4) with both wrist extension and cervical contralateral lateral flexion (NTPT1WE+CLLF). In the fifth variant, the wrist was extended from a preloaded position (WENTPT1). The range of elbow and wrist extension when a submaximal discomfort was elicited was measured with 2 electrogoniometers. RESULTS: The addition of each test component resulted in a significantly reduced ROM (NTPT1NEUTRAL: 179.5 +/- 8.8 degrees, NTPT1WE: 169.0 +/- 13.9 degrees, NTPT1CLLF: 154.7 +/- 13.2 degrees, NTPT1WE+CLLF: 143.9 +/- 16.1 degrees; WENTPT1: 67.1 +/- 11.0 degrees). Sensory responses were predominantly evoked at the region of the added component. CONCLUSIONS: The different test components, whose mechanical influence on the nervous system has been demonstrated in anatomical studies, also have an effect on joint ROM and sensory responses during neurodynamic testing, when individually or simultaneously added. If the nerve bedding is elongated throughout its whole length, the available ROM is markedly reduced and sensory responses can be elicited throughout the entire arm.

Hip fractures in the elderly. Mortality, functional results and social readaptation.

Six-hundred and fourteen aged over 70 and presenting hip fractures have been studied prospectively. The results were compared with the literature. The overall mortality rate within three months was 24%. This mortality was significantly influenced by the general health condition of the patient at the time of the injury, his living conditions and the possibility of walking again after the operation (p less than 0.001). For 38% of the survivors, the fracture means a considerable loss of functional independence. The adjacent impairment was in close relationship with patient's age and fracture-type (p less than 0.05). Sixty per cent of the patients were able to return home. In predicting the probability of returning home, the functional status before injury and the possibility of walking at the moment of discharge were particularly important (p less than 0.001).

Home-going: prognostic factors concerning the major goal in treatment of elderly hip fracture-patients.

Two hundred and forty-one hip fracture patients over 70 years of age still living at home at the moment of the accident were followed prospectively until three months postoperatively. The patients were admitted to the department over a five year period (1978-1983). One hundred and forty-four patients returned home. In order to predict whether an elderly hip fracture patient will be able to return home within three months, the following prognostic factors will have to be taken into account: pre-operative functional status (p = 0.0001), ambulatory capacity at discharge (p = 0.0001), age (p = 0.001), presence of relatives at home to return to (p = 0.02) and general medical postoperative complications (p = 0.0006). In this respect it was noted that sex, fracture type or mechanical complication with possible operation do not significantly influence the home-going rate within three months after surgery (p greater than 0.05).

Polytrauma in patients of 65 and over. Injury patterns and outcome.

In a consecutive series of 416 patients with multiple injuries, 49 were aged 65 years or older (mean age 72.1). This group of "old" patients was compared with the remaining 367 "young" patients (mean age 31.3). In the old patients group, survivors and non-survivors were profiled. In general the injured old patient was a pedestrian hit by a car or a motorbike or someone who had simply fallen at home. Despite the fact that the mean Injury Severity Score (ISS) was significantly lower in the old patients' group (33.2 versus 42.1) (p less than 0.001), the mortality rate was significantly higher (18% versus 7.6%) (p less than 0.05). We found that in the elderly injured the ISS and preexisting diseases were not predictive of survival. However, brain injury with unconsciousness and the need for early intubation followed by long-term assisted ventilation were predictive of survival (p less than 0.001). Seventy-six per cent of the survivors were able to return home again within six months. As the final outcome in the elderly is no worse after polytrauma than after other important emergency procedures, an aggressive treatment including urgent operative fixation of major fractures is in our opinion justified.

Internal fixation of femoral neck fractures. A follow-up study of 118 cases.

A retrospective study of 118 femoral neck fractures treated with multiple Knowles pins or with AO (ASIF) cancellous bone screws, and followed for at least 22 months, revealed nonunion in 1/33 undisplaced fractures and in 27/85 displaced fractures. Avascular necrosis was radiographically evident in respectively 2/32 and 19/58 united undisplaced and displaced fractures. Four factors were adversely associated with union: inaccurate reduction, mental confusion, age above 80 years and fixation with less than 6 Knowles pins. Late segmental collapse was not significantly related with any of the 9 analyzed factors. It was concluded that displaced femoral neck fractures in confused patients older than 80 years, or fractures one cannot adequately reduce, should be primarily treated with arthroplasty. Following accurate reduction, internal fixation with less than 6 Knowles pins cannot be recommended.

[The use of Müller hip prostheses for post-traumatic injuries]. / Emploi des prothèses de la hanche de Müller pour des lésions posttraumatiques.

Between 1978 and 1984 373 Müller prostheses have been used in treating post traumatic lesions of the hip joint. Three groups of patients were concerned: elderly people with fresh fractures of the femoral neck; late sequels of femoral neck fractures; late sequels of acetabular fractures. The follow-up period ranged from 18 months to 8 years. Special attention was brought to late mechanical problems and the final functional status of the patients. We could conclude that: 1. Three years after surgery about 50% of the survivors were still in a good functional condition. After 5 years, this number decreased to 35%. 2. Total prosthesis with "banana formed" stem has to be abandoned. After five years signs of loosening were present in nearly all the cases. The functional results of the straight stem prostheses were significantly better. 3. Old people in good general condition with a fresh fracture of the femoral neck are better of with a total hip replacement than with a hemiarthroplasty. 4. Late sequels of acetabulum fractures present a more complex problem. Maybe a total hip arthroplasty is not always the best final solution.

A plate osteosynthesis for femoral shaft fractures in adults.

Between 1978 and 1982 154 femoral shaft fractures were treated in 145 adults in our department of general surgery and traumatology. 52 fractures were nailed intramedullary. We reserved the intramedullary nailing for ideal cases like the transverse and the short oblique fractures in the middle 3/5 of the shaft. 102 fractures were treated by a dynamic compression plate applying the AO principles correctly. Condylar plates were not included in this study. 88 patients with 95 FSF were followed up. In our prospective study a significant relationship was found between the types of fractures, the consolidation, the rehabilitation (including walking), the hospitalisation time and the full weight-bearing results. The prognosis for simple fractures was better than for comminuted fractures. Polytrauma patients showed a significantly slower limb rehabilitation, a longer hospitalisation and a worse clinical result than patients with isolated fractures. A significant relationship was shown between the mobility of the knee and the localisation of the fracture. In the beginning of our study we thought a delayed osteosynthesis (1-2 weeks) should lead to a faster consolidation but afterwards we didn't notice any significant difference with the early operation. General complications were restricted to one fat embolism. Important bone shortening (greater than or equal to 2 cm) was only measured 4 times (4.2%). Distinct rotation or angulation deformities were not observed. Bone infection occurred twice (2.1%). All but two of the 9 comminuted fractures healed within a year in spite of an initial delayed union.

Pertrochanteric fractures in the elderly. Is the Belgian VDP prosthesis the best treatment for unstable fractures with severe comminution?

During a ten year period (1978-1988) 565 patients, aged 70 years and over, suffering a fresh pertrochanteric fracture have been treated in the Department of Traumatology at the University Hospitals of Leuven, Belgium. According to the system of Evans and Jensen, 388 fractures were classified as unstable. Special attention was given to the 324 cases of type I C and I D fractures. The method of treating greatly changed during the period of study. All patients were followed up prospectively during one year. Our study showed that for these unstable fractures, fixation with an angled plate or Ender nails should be forsaken. The overall results of the dynamic hip screw treatment were good (reoperation rate 2%, good functional results in 64%), but as this treatment has a risk for serious collapse and pain in about 80% of all type I D fractures, one could suggest to treat these complex multifragment fractures primarily with an endoprosthesis. This treatment needs no longer to be considered as a severe intervention, as the danger of mechanical complications being very minimal (less than 1%).

Multiple trauma in patients of 65 and over. Injury patterns. Factors influencing outcome. The importance of an aggressive care.

In a first study of 416 polytrauma patients, 49 were aged 65 years or older. These "old patients" (mean age 72.1) were compared with the remaining 367 "young patients" (mean age 31.3). In a second study concerning 126 polytrauma patients of 65 and over, the survivors and non survivors were profiled and compared. The typical injured old patient was a pedestrian hit by a car or a motorbike or someone who had simply fallen at home. Despite the fact that the mean Injury Severity Score (ISS) was significantly lower in the old patients' groups (33.2 versus 42.1 degrees) (p < 0.0001) the mortality rate was higher (18% versus 7.6%) (p < 0.05). In old trauma victims multiple system organ failure (MSOF) was responsible for the fatal outcome in 48% of the cases and in 71% of the deaths more than 7 days after trauma. Seventy eight percent of the surviving old patients still living at home pre-injury were able to go back to their normal surroundings. In the old patients groups there was no significant difference in age nor in ISS nor in pre-existing diseases between survivors and non-survivors. On the other hand the Glasgow Coma Scale (GCS) was of important prognostic value, as well as to survival as to functional recovery (p < 0.001). Also the need for early intubation and continued ventilation were predictive of survival (p < 0.001). Nevertheless this need for respiratory assistance was not an indication for withdrawing support as also 9% of the survivors required endotracheal intubation for 5 days or longer.(ABSTRACT TRUNCATED AT 250 WORDS)

Peripheral cutaneous nerve distribution to the fingers.

Both sensory distribution charts and the unaffected side, are used as reference points in the assessment of cutaneous innervation. Sensory nerve conduction studies, in particular, often use comparison between sides. However, remarkable differences can be found between various sensory innervation maps, and no evidence was found in the literature for the assumption that the pattern of cutaneous sensory distribution of the peripheral nerves between the left and right limbs is symmetrical. The purpose of this study was to investigate variations in the sensory innervation of the fingers by means of a neurophysiological method, and to compare the results for the left and right hands. The subjects of this study were 31 young women. Percutaneous peripheral nerve stimulation was performed on the four nerve branches providing sensory innervation to the fingers, and action potentials were sought from the fingers by use of annular surface electrodes. Variations in the cutaneous innervation of the fingers between individuals often occurred and were found more frequently on the dorsal than the palmar aspect. The distribution of sensory innervation may even differ markedly between hands in the same individual. The cutaneous innervation of all peripheral nerves supplying the fingers may differ from the innervation patterns described in the various distribution charts. Prudence is called for when applying sensory distribution charts as absolute references for the assessment of cutaneous sensation in patients. Caution should also be applied when comparing one hand with the other when assessing the cutaneous innervation of the fingers.

[Hip fractures in the elderly; mortality, functional results and probability of returning home]. / Heupfracturen bij bejaarden; sterfte, functionele resultaten en kans op huiswaarts keren.

767 patients over the age of 70 with a fracture of one hip were studied prospectively. The results were compared with the literature. The overall mortality rate within 3 months was 24%. This mortality was significantly influenced by the general health condition of the patient at the time of the injury, his living quarters and the ability to walk again after operation (p less than 0.001). For 38% of the survivors, able-bodied before the injury, the fracture meant an important loss of functional independence. The degree of impairment was closely related to the patient's age and fracture type (p less than 0.05). Of patients living in their own homes before injury only 60% were able to go back home. In predicting the probability of going back home, the functional status before injury and the ability to walk again at the time of discharge from the surgical department were highly important (p less than 0.001).

Effect of forearm rotation on grip strength.

Forearm rotation affects grip strength. In a study with 40 volunteers, an overall decrease in grip strength was observed when the forearm rotated from pronation to supination. In males grip strength in pronation was significantly lower compared to the neutral and supinated position, with the wrist free as well as in an immobilized wrist position. In females this was only observed with a free wrist position, but with the wrist immobilized, the grip strength was higher in supination compared to neutral and pronation.

Randomized controlled trial on physical therapy for TMJ closed lock.

This study evaluated the one-year effect of physical therapy on pain and mandibular dysfunction associated with anterior disc displacement without reduction of the temporomandibular joint (closed lock). Forty-nine individuals were randomly assigned to either a physical therapy group [n = 23, mean age (SD) 34.7 (14.0) yrs] or a control group [n = 26, mean age 38.5 (15.1) yrs]. At baseline and after 3, 6, 12, 26, and 52 wks, pain and mandibular function were evaluated. All patients received extensive information about avoiding parafunctions and oral habits on all evaluation days. The physical therapy group received, in a 6-week period, 9 sessions of physical therapy, including joint mobilization, exercises, and massage, and the information on avoiding parafunctions and oral habits was repeated each time. All pain variables decreased, and all function variables increased significantly over time for both groups. The interaction between time and treatment group was not significant. Hence, physical therapy had no significant additional effect in patients with anterior disc displacement, without reduction, of the temporomandibular joint (ClinicalTrials.gov number, CT01475630).

One-year evaluation of the effect of physical therapy for masticatory muscle pain: a randomized controlled trial.

Physical therapy is widely used to decrease pain and restore function in patients suffering from masticatory muscle pain. Controlled studies on its efficacy are scarce. This study evaluated the 1-year effect of a 6-week physical therapy programme in a single blind, randomized, controlled trial. Fifty-three subjects were randomly assigned to either a physical therapy group [n = 26; 19 women, mean age (SD) 36.6 years (15.5 years)] or a control group [n = 27; 20 women, mean age (SD) 42.9 years (15.1 years)]. In the physical therapy group, the patients received education, muscle stretching, exercises and homework for nine treatments in 6 weeks. In the control group, the patients received education on the evaluation days only. At baseline and after 3, 6, 12, 26 and 52 weeks, pain and masticatory function were evaluated using visual analogue scales, the McGill Pain Questionnaire, pressure pain thresholds of the masseter and temporalis muscles, the mandibular function impairment questionnaire, and active and passive maximal mouth opening. All pain rating variables decreased and all function variables increased significantly over time in both groups. No significant differences in improvement between the groups (time-treatment interaction) were found. These data suggest that the long-term decrease in pain and the improvement of function are not related to active physical therapy.
