Hand function following single ray amputation

We retrospectively studied primary and reconstructive single ray resection at 16 to 150 months after surgery (median, 41 months) in 25 patients (18 males) whose average age was 28 years. Cases were reviewed 16 to 154 months after surgery (median, 41 months). The injuries involved 14 dominant and 11 nondominant hands. Twelve patients had primary ray resection (< or =2 weeks after injury) and 13 had secondary/reconstructive amputation of 18 border and 7 central digits. Examinations and functional testing by Minnesota rate of manipulation and timed grooved pegboard tests were done and x-rays were reviewed. The majority of patients were subjectively satisfied with the appearance and function of the hand. Patients lost an average of 13 weeks of work (range, 2-24 weeks); those with primary resection were out of work 9 weeks (range, 2-17 weeks) and patients who had secondary resection lost a total of 16 weeks of work (range, 7-24 weeks). Twenty-one of the 25 patients returned to their preinjury occupation. Evaluation of nonwork plus settled workers' compensation cases versus nonsettled compensation/litigation cases showed that there were statistically significant differences in grip strength, key pinch, oppositional pinch, and Minnesota rate of manipulation test results. Primary ray removal limits the total costs associated with injury and disability; unsettled compensation/litigation issues produce statistically disparate and otherwise physically inexplicable differences.

Dynamic treatment of displaced proximal phalangeal fractures

We report a splint system for a protected mobilization program (termed dynamic treatment) of proximal phalangeal fractures. This program can be used for nonoperative treatment or after operative treatment. Intra-articular fractures of the proximal phalanx at the metacarpophalangeal joint were included. The custom-molded 2-component thermoplastic splint allows motion of the proximal and distal interphalangeal joints. It was developed to allow bone healing and recovery of motion at the same time. We evaluated the clinical and radiologic results of a consecutive series of 48 displaced proximal phalangeal fractures in 45 patients who received dynamic treatment. Fracture consolidation was achieved in all patients and bone healing and recovery of full active motion was achieved simultaneously in all but 4 patients by 6 weeks. The advantage of this splint system is the variability of its application. The splint can be used both for nonsurgical and surgical management. It can be removed to change dressings and for radiologic evaluations. The period of dynamic treatment can be determined individually in each case.

Effects of increased in vivo excursion on digital range of motion and tendon strength following flexor tendon repair

Postoperative rehabilitation is an important factor in determining functional outcome following intrasynovial flexor tendon repair. We hypothesized that a rehabilitation protocol that produced increased in vivo excursion would lead to increased digital range of motion and tendon strength and decreased adhesion formation in a canine model. Ninety-six flexor digitorum profundus tendons from 48 dogs were cut transversely and repaired by a multistrand suture technique. Postoperative rehabilitation was performed daily with a low excursion-low force (1.7-mm average excursion; < 10 N force) or a high excursion-low force (3.6 mm excursion; < 10 N force) protocol. After death of the dogs at 10, 21, or 42 days, specimens were evaluated for digital range of motion, tensile mechanical properties, elongation of the repair site, and adhesion formation. Our data indicate that the range of motion of digits whose tendons were at low or high excursion was similar to that of controls. Increased in vivo tendon excursion due to synergistic wrist motion did not significantly affect ex vivo flexion of the distal and proximal interphalangeal joints or tendon displacement (p > 0.05). Similarly, tensile properties (ultimate load, repair site rigidity, and repair site strain at 20 N and at failure) and length of the gap at the repair site were not significantly affected by increased excursion (p > 0.05). Severity of adhesion formation was reduced slightly by increased excursion (p = 0.04). Our findings indicate that 1.7 mm of tendon excursion is sufficient to prevent adhesion formation following sharp transection of the canine flexor tendon and that additional excursion provides little added benefit.

Predictors of dysphagia after spinal cord injury

OBJECTIVE

To quantify the incidence of swallowing deficits (dysphagia) and to identify factors that predict risk for dysphagia in the rehabilitation setting following acute traumatic spinal cord injury.

DESIGN

Retrospective case-control study.

SETTING

Freestanding rehabilitation hospital.

PATIENTS

Data were collected on 187 patients with acute traumatic spinal cord injury admitted for rehabilitation over a 4-year period who underwent a swallowing screen, in which 42 underwent a videofluoroscopic swallowing study (VFSS).

MAIN OUTCOME MEASURES

VFSS was performed on patients with suspected swallowing problems. Possible antecedents of dysphagia were recorded from the medical record including previous history of spine surgery, surgical approach and technique, tracheostomy and ventilator status, neurologic level of injury, ASIA Impairment Classification, orthosis, etiology of injury, age, and gender.

RESULTS

On admission to rehabilitation 22.5% (n = 42) of spinal cord injury patients had symptoms suggesting dysphagia. In 73.8% (n = 31) of these cases, testing confirmed dysphagia (aspiration or requiring a modified diet), while VFSS ruled out dysphagia in 26.2% (n = 11) cases. Logistic regression and other analyses revealed three significant predictors of risk for dysphagia: age (p < .028), tracheostomy and mechanical ventilation (p < .001), and spinal surgery via an anterior cervical approach (p < .016). Other variables analyzed had no relation or at best a slight relation to dysphagia. Tracheostomy at admission was the strongest predictor of dysphagia. The combination of tracheostomy at rehabilitation admission and anterior surgical approach had an extremely high rate of dysphagia (48%).

CONCLUSION

Swallowing abnormalities are present in a significant percentage of patients presenting to rehabilitation with acute traumatic cervical spinal cord injury. Patients with a tracheostomy appear to have a substantially increased risk of development of dysphagia, although other factors are also relevant. Risk of dysphagia should be evaluated to decrease the potential for morbidity related to swallowing abnormalities.

[Complications and therapy after arthroscopic interventions of the knee joint]

Complications following arthroscopic knee surgery are known from the literature to be relatively rare. It hence is all the more important for the rehabilitation staff to know the possible risks for complications. Usually it is quite sufficient to perform a good clinical examination in case of complications in order to be able to carry out the necessary therapeutic measures in regular contact with the surgeons involved. Among the most dangerous complications requiring immediate therapy are the extraarticular vascular complication, the knee joint infection, and the intraarticular bleeding complication. Responsible teamwork among surgeons and rehabilitation staff will be the key to a successful treatment outcome.

[Manual therapy in the rehabilitation of patients with ischemic heart disease in the early period following myocardial revascularization]

Therapeutic complexes eliminating anginal and nonanginal pain syndromes including physiotherapy and manual therapy have been developed and tried in 57 patients with coronary heart disease early after surgical treatment. The addition of manual therapy in the rehabilitation complex shortens duration of rehabilitation, corrects post-operative angina and reflex pain syndrome in the chest and shoulders.

[Post-therapeutic lymphedema of the arm--possibilities and limits of diagnosis and therapy]

The post-therapeutical secondary arm lymphedema is the most frequent complication after a curatively treated cancer of mamma. For the diagnosis and therapy the knowledge of physiology and pathophysiology of lymphedema and of specific anatomy are necessary. The diagnosis facilities are essentially limited to a basic diagnosis (anamnesis, inspection, palpation, sonography, functional-diagnosis). Specific apparative diagnostics like lab, sonography, CT, MRI and PTE have to be applied especially at an early stage of the secondary arm lymphedema for the differential diagnosis between the secondary malign and secondary benign arm lymphedema. Specific apparative examinations like lymphscintigraphy and lymphography are limited and solely indicated for special questions. As a therapy possibility of the secondary arm-lymph edema, a conservative therapy, that is, the complex two-stage-decongestive physiotherapy (CDP) is recommended as first choice. Surgical therapies such as autologous lympho-lymphostatic anastomoses and lymphovenous anastomoses are only recommended in selected individual cases. The secondary malignant arm lymphedema must be primarily treated oncologically; lymphological therapy measures have to be postponed. Diagnosis and therapy are limited through lymphological incompetence and insufficient patient compliance. In this respect the provision of financial resources through National Health policy ist regarded as utterly important.

Hand surgery and quality of life

The outcome in patients having surgery to the hand was assessed subjectively using a questionnaire that covered activities of daily living (ADL), hand pain and psychological well-being. The questionnaires were completed on average 6.9 months preoperatively and 20.6 months postoperatively by 15 patients with osteoarthritis undergoing trapeziectomy and 25 patients with rheumatoid arthritis undergoing Swanson arthroplasties of the metacarpophalangeal joints. Surgery resulted in significant improvements in reported ADL and hand pain, in both groups. Improvement in perception of hand function and health was only seen in the osteoarthritic group. There was no improvement in arthritis activity, mood or quality of life in either group. These results confirm that surgery for arthritis of the hand relieves pain and improves ADL. However, it has a greater effect in patients with localized osteoarthritis than in those with rheumatoid arthritis.

Follow-up after carpal tunnel decompression - general practitioner surgery or hand clinic? A randomized prospective study

We prospectively randomized 100 patients following carpal tunnel decompression who were having a 2-week postoperative assessment and removal of stitches to either their local general practitioner (GP) or the hospital outpatient department. All patients were seen at hospital 6 weeks postoperatively for a final assessment. The waiting time for assessment and suture removal was shorter at the GP surgery than in the outpatient department (mean 13 min and 28 min respectively) but significantly more patients were diagnosed as having wound infections (14% and 0% respectively); most were given antibiotics, perhaps unnecessarily.

Considerations for free-flap reconstruction of the hard palate

OBJECTIVE

To evaluate the use of microvascular free-tissue transfers in the reconstruction of hard palate defects.

DESIGN

Retrospective review of a case series.

SETTING

Two tertiary referral centers.

PATIENTS

Thirty patients had hard palatal defects that resulted from ablative oncologic surgery: 10 total or subtotal palatal defects, 14 hemipalatal defects, and 6 anterior arch defects.

INTERVENTION

Nine fibular, 11 rectus abdominus, 3 scapular, 6 radial forearm, and 1 latissimus dorsi free flaps were used to reconstruct these defects.

MAIN OUTCOME MEASURES

Separation of the oral cavity from the nasal and sinus cavities, complications, oral diet, speech intelligibility, and overall quality of life.

RESULTS

No flap failures occurred, and all palatal defects were ultimately sealed. Nineteen patients eat a regular diet, while the remainder maintain a soft diet. Twelve patients use a conventional dental prosthesis; 8 of the dental prostheses are supported by implants. Of 23 patients examined for speech, 18 have no disorders, 3 exhibit hyponasal speech, and 2 have hypernasal speech. Overall University of Washington, Seattle, quality of life scores were fair in 2 patients, good in 6, and excellent in 12.

CONCLUSIONS

Free-flap reconstruction of the palate provides reliable permanent separation of the oral and sinonasal cavities in one stage. In addition, the potential for dental rehabilitation with the restoration of masticatory function and normal phonation exists. Flap choice is tailored to specific palatal defects as well as patient needs.

[The gait of patients with full weightbearing capacity after hip prosthesis implantation on the treadmill with partial body weight support, during assisted walking and without crutches]

PROBLEM

Treadmill training with partial body weight support is a new promising technique in the rehabilitation in hip arthroplasty patients. With little data on the gait pattern and extent of pelvitrochanteric muscle activation, this study analysed the gait of hip arthroplasty patients walking on the treadmill and also during floor walking with and without crutches.

METHOD

Gait analysis in 19 hip arthroplasty patients capable of full weight bearing included the assessment of kinematics, kinetics and kinesiologic electromyogram of relevant trunk and lower limb muscles during treadmill walking with 15% of body weight support, and during floor walking with and without crutches at comparable walking velocities.

RESULTS

Both on the treadmill and with crutches, patients walked less frequent, with a longer stride and more symmetric as compared to the unaided gait. Both techniques, however, resulted in a reduced activation of most of the pelvitrochanteric muscles, particularly when using crutches. The comparison of both supporting methods revealed a higher activity of the M. gluteus medius of the affected side on the treadmill. The amount of body weight reduction was comparable ranging from 10 to 15%.

CONCLUSIONS

Treadmill training with constant body weight support enables hip arthroplasty patient to entrain a dynamic and symmetric gait pattern with a better activation of the hip abductor of the affected side as compared to walking with crutches. Nevertheless, the level of activation was less than when walking without crutches which, however, resulted in a limping gait pattern.

[Experiences with ambulatory cardiologic phase II rehabilitation]

The phase II cardiac rehabilitation in Germany differs markedly from other European countries and the USA. Most of the patients enter a 3-week full residential program. In contrast we developed an outpatient phase II cardiac rehabilitation program. Since 1979 we treated more than 8,500 patients with different indications (i.e. after myocardial infarction, coronary bypass surgery, valve replacement and reconstruction). Patients with a daily commuting time over 60 minutes are not suitable for outpatient rehabilitation. Our model corresponds to the German intrahospital rehabilitation. The rehabilitation is carried out in 3 weeks offering approximately 66 hours of therapy. Groups of 8 patients with a similar level of physical capacity stay together during the rehabilitation. A comprehensive program with exercise training, physical therapy, psychological support, education in life style changes and risk factor modification has been developed. The compliance of the patients as well as the acceptance by the family are excellent. Long-lasting reduction in LDL cholesterol levels and increments in work-load capacities have been demonstrated. A high percentage of patients returned to work. Cost analysis demonstrates a reduction up to 40% in comparison to the full residential program. Therefore the outpatient phase II cardiac rehabilitation is a good alternative especially in urban areas.

[Clinical follow-up 6 months after ambulatory/partial inpatient after-care rehabilitation. Further results of the Cologne model of ambulatory cardiac phase II rehabilitation]

Three hundred and thirty patients with coronary artery disease (CAD) (288 men, 42 women, age of 55.5 +/- 10.0 years) participated in a 4-week ambulatory cardiac rehabilitation program (ACR) (Table 1). The cardiovascular indication for ACR was in 229 cases a myocardial infarction. In 101 patients a CAD with invasive revascularization but without a history of MI was present. In 92 patients with myocardial infarction additionally an invasive revascularization was performed. Eighty-three patients were included after a CABG-procedure (Tables 2 to 5). Six months after the ACR 290 (87.9%) patients presented for clinical reevaluation. In 235 (81.0%) of the 290 examined patients the cardiovascular diagnosis was unaltered. In the first 6 months after ACR in 76 (26.2%) patients a coronarography was performed, in 44 patients a restenosis was diagnosed. In 36 patients an additional invasive procedure (in 28 patients a PTCA, in 5 patients with additional stent-implantation, in 1 case with rotablation, in 8 patients CABG) was performed. In 1 patients a pace-maker was implanted. Since the ACR 1 patient experienced a myocardial infarction and 2 a recurrent myocardial infarction. In 1 patient myocardial fibrillation occurred. Totally, 70 patients (24.1%) required stationary-hospital treatment during the first 6 months after ACR (Table 6). In 11 cases an acute admission to hospital treatment because of cardiovascular reasons was documented. The majority of the hospital admission was elective, because of diagnostic or therapeutic procedures. In 6 patients a CABG-surgery was performed. In approximately 80% of the patients the cardiovascular status was stable during the first 6 months after ACR. Though 24.1% of the patients required stationary hospital treatment, the majority of the admissions was elective of interest, there was a high rate of hospital admissions in the PTCA-group in combination with recoronarographies and revascularization because of early reocclusion.

[The staged medical rehabilitation of patients with secondary chronic pyelonephritis in infravesical obstructions]

The authors believe that chronic pyelonephritis patients operated for infravesical obstructions need staged postoperative rehabilitation. In antibacterial postoperative treatment, a significant response was seen in 7.9%, a partial response in 18.4% and no response in 73.7% of patients. After combined physiotherapy--in 38%, 41.7% and 20.3% of patients, respectively.

Cochlear reimplantation

OBJECTIVE

A small number of multichannel cochlear implant (CI) recipients require reimplantation. This study describes the causes of failure, surgical technique, and hearing outcomes in a consecutive series of 16 patients undergoing reimplantation of multichannel devices. We hypothesize that reimplantation is safe and that hearing results are at least as good as those measured following primary implantation.

STUDY DESIGN

Retrospective analysis of consecutive clinical series.

METHODS

Chart analysis of 191 consecutive CI operations performed at the University of Miami Ear Institute between 1990 and 1997 revealed 16 patients who received a second multichannel device. All but one had a minimum follow-up of 1 year after reimplantation. Ten of these patients had initial implantation performed by us, and six were initially operated on elsewhere. Main outcomes of the initial procedure were compared with those of the reimplantation, including electrode insertion length, number of channels programmed, and audiometric results. In addition, cause of failure and relevant surgical findings at the second procedure are described.

RESULTS

There were no surgical complications after reimplantation surgery. Device failure was the most frequent cause for reimplantation. Time between initial implantation and failure ranged from 0 to 46 months (mean, 22.4 mo; median, 23 mo). Common intraoperative findings include mastoid fibrosis, bone growth at the cochleostomy, and skin flap breakdown. Following reimplantation, mean length of insertion, number of channels actively programmed, and speech recognition scores were at least as good as findings before initial implant failure.

CONCLUSION

CI reimplantation is safe and effective.

[The benefit of head rotation on pharyngoesophageal dysphagia from three cases of paraganglioma in the parapharyngeal space]

The benefit of head rotation to the affected side is indicated during swallowing in patients complaining of dysphagia with unilateral pharyngeal palsy and/or laryngeal palsy. We experienced three cases of severe dysphagia after operations for giant paragangliomas (two vagal paraganglioma and one carotid body tumor) in the parapharyngeal space. During operation, the transmandibular transpterygoid approaches were applied to ensure better surgical views, and tracheostomy was performed to keep the airway open after operation. In each case, dysphagia during the pharyngeal stage of swallowing was significantly improved with rehabilitation using of this head rotation. We believe that rather than forbid oral intake, using an active bolus with head rotation is important for cases where dysphagia in the pharyngeal stage of swallowing is present with unilateral pharyngeal and/or laryngeal palsy. Repetitive swallowing exercises are important to reacquire the complicated movement of swallowing. Additionally, an active bolus flowing into the pyriform sinus on the healthy side will prevent a relaxation disorder of the cricopharyngeal muscle on that side. Furthermore, compensatory movement of the arytenoid on the healthy side improves dysphagia. We emphasize the usefulness of head rotation during swallowing rehabilitation for dysphagia with unilateral pharyngeal and/or laryngeal palsy in spite of its simplicity.

[Passive electrostimulation therapy of the anal sphincter is inferior to active biofeedback training]

Anal incontinence can be treated by conservative therapy if a significant anatomical sphincter defect has been excluded. We compared electrostimulation therapy with biofeedback training in a prospective study. Results showed that up to two thirds of all patients can be treated successfully, whereby the results of biofeedback were better than those of electrostimulation.

Postsurgical rehabilitation of Dupuytren's disease

Postoperative rehabilitation is an important component in the management of Dupuytren's disease patients. Through an effective splinting and exercise program, the surgical outcome can be enhanced. Treatment should be directed toward restoring hand function and monitoring development of complications that could compromise the outcome.

Facial reanimation with jump interpositional graft hypoglossal facial anastomosis and hypoglossal facial anastomosis: evolution in management of facial paralysis

When viable proximal facial nerve is inacessible, facial nerve paralysis has been classically managed with the hypoglossal facial anastomosis (HFA) for at least the past 70 years. While this procedure has proven its reliability, its problems with hemilingual atrophy (speech deglutition, drooling, mastication), hypertonia, synkinesis, and mimetic deficits indicate the need for a more perfect solution for facial paralysis. The jump interpositional graft hypoglossal facial anastomosis (JIGHFA) along with gold weight lid implantation and electromyographic (EMG) rehabilitation achieves substantial facial reanimation without hemilingual deficits. We present our results in 18 patients who underwent JIGHFA along with gold weight lid implantation and EMG rehabilitation for facial paralysis. These results were compared with those from published series of 30 patients treated with HFA with EMG rehabilitation evaluated with objective (House-Brackmann) criteria. Anonymous retrospective information from questionnaires from 22 of 48 patients who were treated with the classic HFA was also presented. In properly selected patients, the JIGHFA technique is capable of achieving substantial facial reinnervation (House-Brackmann grade III or better) in 83.3% of the patients without hemilingual sequelae which was seen in 45% of the HFA patients. In contrast to the HFA, this procedure can be used by patients with concomitant lower cranial nerve paralysis (except hypoglossal), and bilateral facial paralysis. Hypertonia, synkinesis, and lagophthalmus were less symptomatic in the JIGHFA patients. Mimetic expression was not improved in the JIGHFA population compared with the HFA group.

Comparison between men and women admitted to an inpatient rehabilitation unit after cardiac surgery

OBJECTIVE

To determine whether there are differences in several factors between men and women who undergo inpatient post-cardiac surgery rehabilitation.

DESIGN

A retrospective chart review. Information was collected on a variety of factors: age; previous myocardial infarction; number of days from surgery to admission to rehabilitation; postsurgery, prerehabilitation complications; length of stay on the rehabilitation unit; living arrangements before surgery; disposition; and postdischarge recommendations.

SETTING

Community hospital rehabilitation unit associated with a university hospital.

PATIENTS

One hundred thirty-eight patients (54 men, 84 women) admitted to an inpatient rehabilitation unit after cardiac surgery.

RESULTS

There was a significant relationship between sex and preadmission living arrangements; 56% of women lived alone versus 26% of men (p < .01). There was a statistically significant difference in length of stay on the rehabilitation unit (p < .02). Men stayed longer, with a median stay of 16 days (95% confidence interval, 15 to 20) versus 15 days for women (95% confidence interval, 14 to 15). Ninety-three percent of men were discharged from rehabilitation at 30 days versus 98% of women. No relationship was noted between men and women in age, previous myocardial infarction, number of days from surgery to rehabilitation admission, length of stay on the rehabilitation unit, postsurgery-prerehabilitation complications, complications on the rehabilitation unit, presurgery living arrangements, disposition, and postdischarge therapy recommendations.

CONCLUSION

Men and women showed comparable courses after cardiac surgery. Before surgery, women lived alone more frequently than men.
