Cross-cultural adaptation and validation of the Turkish version of the Musculoskeletal Tumor Society scoring system in patients with musculoskeletal tumors.

OBJECTIVE: This study aimed to translate and cross-culturally adapt the musculoskeletal tumor society (MSTS) scoring system into Turkish and to determine the reliability and validity of the translated version for the functional evaluation of patients with musculoskeletal tumors. METHODS: A total of 36 patients (16 women, 20 men; mean age=36.6; age range=13-75 years) who underwent limb-salvage surgery owing to benign aggressive or malignant musculoskeletal tumors were included in the study. Translation and back translations of the MSTS were performed according to the published guidelines. Short form (SF) 36 physical component, Western Ontario and McMaster Universities Arthritis Index (WOMAC), disabilities of the arm, shoulder, and hand (DASH), and range of motion scale (ROMS) that were previously analyzed for Turkish validation were used for validity. Reliability of MSTS Turkish version was evaluated by calculating test-retest reliability and internal consistency. Intraclass correlation coefficient (ICC) was used to evaluate the inter-observer consistency and test-retest reliability. Alpha coefficient (Cronbach's alpha) was used to evaluate the internal consistency. RESULTS: It was observed that total MSTS score has a strong negative correlation with DASH (r=-0.689; p<0.001) and WOMAC scores (r=-0.634; p<0.001) and moderate correlation with the ROMS score (r=0.521; p<0.001). Total MSTS score also had a statistically significant strong correlation with SF-36 scores (r values ranging from 0.425 to 0.609, p<0.001). Inter and intra-observer reliability of the MSTS scale was found to be excellent (Cronbach's α=0.97 p<0.001; ICC: 0.97 (0.96-0.99; p<0.001). Unlike other subscales, statistical correlation between dexterity and hand-positioning subscales of MSTS with DASH scores was found to be insignificant (r=-0.533, p =0.061 and r=-0.336, p=0.261, respectively). CONCLUSION: The Turkish version of the MSTS scoring system seems to be a valid and reliable scale that measures the correct and desired values in the evaluation of health-related quality of life in orthopedic oncology. Reliability coefficients of the Turkish version of MSTS were determined to be strong. LEVEL OF EVIDENCE: Level II, Diagnostic Study.

Limb salvage surgery of primary and metastatic bone tumors of the lower extremity: Functional outcomes and survivorship of modular endoprosthetic reconstruction.

OBJECTIVE: The study was aimed to determine the survivorship and functional outcomes of modular endoprosthetic reconstruction in the management of primary and metastatic bone tumors of the lower limbs and to investigate the rate and causes of implant failure. METHODS: A total of 84 limbs of 82 patients (49 male, 33 female; mean age=48 years, age range=13-78 years) with a minimum follow-up of 12 months in whom resection and modular endoprosthetic reconstructions were performed for primary or metastatic bone tumors of the lower extremity were retrospectively reviewed and included in the study. The mean follow-up was 43 (range=13-119) months. Functional status was assessed using the Musculoskeletal Tumor Society (MSTS) scoring system at the final follow-up. Implant survival was defined as the time from implantation until partial or complete exchange of the prosthesis secondary to mechanical or nonmechanical causes or amputation. The effects of the anatomical site on functional scores and implant survival were statistically analyzed. Additionally, the effects of diagnosis and adjuvant treatments on functional scores, implant survival, and failure rates were investigated. RESULTS: At the time of the study, 55 patients were still alive with a mean follow-up of 48 (range=15-119) months. The mean MSTS scores resulting from the final follow-up of all patients and of those surviving were 87.9% (range=16%-100%) and 86.8% (range=16%-100%), respectively. Overall implant survival was 95.2%, 89.2%, 87%, and 87% at 1, 2, 3, and 4 years, respectively. Statistically, both functional scores and implant survival analysis in different anatomical sites were found similar. In 15 of the patients (17.8%), endoprosthetic reconstructions had failed. The causes of failure were soft tissue failure (dislocation) in 5 patients, infection in 5, structural/mechanical failure in 2, local recurrence in two, and aseptic loosening in one. The diagnosis and receiving preoperative and/or postoperative adjuvant treatment did not affect functional scores, implant survival or failure rates. CONCLUSION: The results of this study have shown that modular endoprosthetic replacement can provide satisfactory functional results and a durable mid-term limb salvage option in the management of patients with primary and metastatic bone tumors of the lower limbs.

Sports activity after soft tissue sarcoma of the lower extremity.

Introduction: The aim of this case series was to assess sports activity levels in long-term survivors of soft-tissue sarcomas after multimodal treatment including limb salvaging surgical resection and radio-chemotherapy.Methods: Thirty-two patients (17 f/15 m) with a mean age of 29 (range 10-44) years at the time of diagnosis and a mean follow-up time of 9 (range 3-21) years following sarcoma were included. Ten patients had been diagnosed with liposarcoma, seven with synovial sarcoma, four with fibrosarcoma, three with undifferentiated pleomorphic sarcomas and the remaining eight patients with different soft-tissue sarcoma entities. Sarcoma location of twenty-four (75%) patients was in the thigh, eight (25%) in the lower leg. Eleven (34%) tumors were located epifascial, 21 (66%) in deeper tissue layers. Sports activity was measured by the University of California, Los Angeles (UCLA) Activity Score.Results: One year before treatment 30 patients (94%) and >3 years post-treatment 29 patients (91%)had been pursuing athletic activity regularly. They were performing 5.5 h/week prior and 4.2 h/week >3 years post surgery. The mean UCLA score in case of subfascial sarcomas was 8.0 and thereby lower (p < 0.05) than those of epifascial sarcomas, which were 9.3. Furthermore, the mean UCLA score after subfascial sarcoma resection 3 years postoperative was still below preoperative UCLA levels (p < 0.05), whereas patients after epifascial tumor resection showed no loss of sports activity. No relation between complications and postoperative sports activity level was found.Conclusions: Healthy long-term survivors can achieve high levels of sports activity following limb salvage after soft-tissue sarcomas. The concerned muscle groups may influence the functional and sports outcome and draw attention to this topic in future rehabilitation. This knowledge may be of high value for patients counseling, physicians and orthopedists treating patients, as well as for patients inquiring information regarding post-treatment activity levels.Implication for rehabilitationSport is possible after soft tissue sarcoma treatment and longer-term rehabilitation which is usually three yearsRehabilitation is best undertaken in specialized centersIt is important to maintain contact with surgeons in order to optimize mobilizationHigh impact sports may be affected by deep muscle resections.

Reliability of StepWatch Activity Monitor to Measure Locomotor Activity in Youth With Lower Limb Salvage.

PURPOSE: The study purpose was to determine the minimum number of monitoring days necessary to reliably capture walking among individuals with lower limb salvage. METHODS: Nineteen participants with lower limb salvage wore an ankle-mounted motion sensor over a 7-day period to obtain step counts. Generalizability theory was used to examine the variance components in step counts (G study) and to determine the appropriate length of activity monitoring using various combinations of days (D study). RESULTS: Mean step counts were higher on weekends than on weekdays. Fifty percent of the total variance in step counts was accounted for by interindividual variability in walking (D study). Eighty percent was reached individually with 4 weekdays, 2 weekend days, or 3 week days + weekend days. CONCLUSION: The study provides data for an appropriate monitoring method to track walking outcomes of rehabilitation for individuals with lower limb salvage.

Limb-sparing sarcoma reconstruction with functional composite thigh flaps.

INTRODUCTION: Innervated muscle transfer can improve functional outcomes after extensive limb-sparing sarcoma resections. We report our experience using composite thigh flaps for functional reconstruction of large oncologic extremity defects. PATIENTS AND METHODS: Between 2011 and 2014, four limb-sparing oncologic resections (3 lower extremities, 1 upper extremity) underwent immediate functional reconstruction with composite thigh free flaps in three males and one female. The age of the patients ranged from 36 to 73 years. There were 3 soft-tissue sarcomas and one giant cell tumor, all required resection of entire muscle compartments. Flap components included fasciocutaneous tissue with sensory nerve, plicated iliotibial band (ITB), and variable amounts of motorized vastus lateralis (VL). RESULTS: All flaps survived without complications. All patients showed VL motor innervation by six months. Follow-up ranged from 20 to 36 months. Motor strength ranged from 2 to 5 out of 5, active range of motion was 25-92% of normal, and Musculoskeletal Tumor Society (MSTS) Scores were between 22 and 29 out of 30. CONCLUSIONS: Limb-sparing techniques for upper and lower extremity sarcomas continue to evolve. Our experience has validated the composite thigh free flap as an excellent option for one-stage functional reconstruction of large limb defects.

Free flap reconstruction for diabetic foot limb salvage.

BACKGROUND: Although free flap is gaining popularity for the reconstruction of diabetic foot ulcers, it is unclear whether free flap reconstruction increases the chances of postoperative independent ambulation. The aim of this study is to evaluate the relationship between free flap success and postoperative ambulation. METHODS: This study reviewed 23 cases of free flap reconstruction for diabetic foot ulcers between January 2007 and March 2014. Free rectus abdominis, latissimus dorsi, and anterolateral thigh flaps were used in ten, eight, and five patients, respectively. A comparison was made between free flap success and postoperative independent ambulation using Fisher's exact test. RESULTS: Two patients developed congestive heart failure with fatal consequences within 14 days postoperatively, resulting in an in-hospital mortality rate of 8.7%. Five patients lost their flaps (21.7%). Of the 16 patients who had flap success, 12 achieved independent ambulation. Five patients with flap loss did not achieve independent ambulation, except one patient who underwent secondary flap reconstruction using a distally based sural flap. Fisher's exact test revealed that independent ambulation was associated with free flap success (p = 0.047). CONCLUSION: The present study indicates that free flap reconstruction may increase the possibility of independent ambulation for patients with extensive tissue defects due to diabetic ulcers. Intermediate limb salvage rates and independent ambulation rates were favourable in patients with successful reconstruction. The use of foot orthoses and a team approach with pedorthists were effective to prevent recurrence.

Amputation: Not a failure for severe lower extremity combat injury.

INTRODUCTION: The use of improvised explosive devices is a frequent method of insurgents to inflict harm on deployed military personnel. Consequently, lower extremity injuries make up the majority of combat related trauma. The wounding pattern of an explosion is not often encountered in a civilian population and can lead to substantial disability. It is therefore important to study the impact of these lower extremity injuries and their treatment (limb salvage versus amputation) on functional outcome and quality of life. PATIENTS AND METHODS: All Dutch repatriated service members receiving treatment for wounds on the lower extremity sustained in the Afghan theater between august 2005 and August 2014, were invited to participate in this observational cohort study. We conducted a survey regarding their physical and mental health using the Short Form health survey 36, EuroQoL 6 dimensions and Lower Extremity Functional Scale questionnaires. Results were collated in a specifically designed electronic database combined with epidemiology and hospital statistics gathered from the archive of the Central Military Hospital. Statistical analyses were performed to identify differences between combat and non-combat related injuries and between limb salvage treatment and amputation. RESULTS: In comparison with non-battle injury patients, battle casualties were significantly younger of age, sustained more severe injuries, needed more frequent operations and clinical rehabilitation. Their long-term outcome scores in areas concerning well-being, social and cognitive functioning, were significantly lower. Regarding treatment, amputees experienced higher physical well-being and less pain compared to those treated with limb salvage surgery. CONCLUSION: Sustaining a combat injury to the lower extremity can lead to partial or permanent dysfunction. However, wounded service members, amputees included, are able to achieve high levels of activity and participation in society, proving a remarkable resilience. These long-term results demonstrate that amputation is not a failure for casualty and surgeon, and strengthen a life before limb (damage control surgery) mindset in the initial phase. For future research, we recommend the use of adequate coding and injury scoring systems to predict outcome and give insight in the attributes that are supportive for the resilience that is needed to cope with a serious battle injury.

Can a Made-for-Consumer Activity Monitor Assess Physical Activity in Adolescents and Young Adults After Lower Extremity Limb Salvage for Osseous Tumors?

BACKGROUND: The purpose of this study was to test the validity of a consumer-oriented activity monitor in adolescents and young adults undergoing limb salvage for primary bone malignancies. METHODS: A cross-sectional population of participants with an average age of 16 (range 12 to 22) years produced 472 days of activity monitoring during 25 evaluations periods alongside patient-reported outcome measures. RESULTS: Average daily steps ranged from 557 to 12,756 (mean=4711) and was moderately associated with the short-form (SF) 36 physical component subscale (r=0.46, P=0.04) as well as the SF6D health state utility measure (r=0.48, P=0.04), but not the SF36 mental component subscale (P=0.66) or Toronto extremity salvage score (P=0.07). Time from surgery was strongly correlated with average daily steps (r=0.7, P<0.001). CONCLUSIONS: A made-for-consumer activity monitor provided real-world data regarding the outcome of adolescent and young adult limb salvage, and evidence of validity in this population. Such lower cost, user-friendly devices may facilitate assessment of free-living activity and allow novel comparisons of treatment strategies. LEVEL OF EVIDENCE: Level II-diagnostic.

Rehabilitation needs in oncological patients: the On-rehab project results on patients operated for musculoskeletal tumors.

BACKGROUND: Rehabilitation plays an important role in improving functional outcome in patients operated on musculoskeletal tumors. Literature in the field is scarce and the specific needs for rehabilitation of these patients are still unknown. AIM: To analyze the rehabilitation needs of patients with primary malignant musculoskeletal tumors. DESIGN: Observational, longitudinal study on both inpatient and outpatient operated on musculoskeletal tumors. METHODS: Rehabilitation needs of oncological patients were explored by means of questionnaires administered by a physician. Demographic, oncological, psychological domains were also assessed. RESULTS: Twenty-nine patients were evaluated in the immediate post-operative period, 25 patients had a follow up at 6 months, and 11 patients at 12 months. Rehabilitation needs concerned essentially the neuromotor function and the improvement of independence at home/outside home. At first admission, support for occupational rehabilitation was also relevant, while its importance was reduced over the follow-up. Pain control need was greater at first admission (VAS over the follow-up 3.3, 0.52, and 1.09, respectively) and required treatment with painkillers. Quality of life (EORTC) increased over the three assessments (respectively 48.80; 71.42; 82.14). The Psychological Distress Inventory (PDI) scores were 26.23, 21.75, 23.6, and the Caregiver Needs Assessment (CNA) scores were 32.69, 27.95, and 31.7 respectively at the three follow up. CONCLUSIONS: The relevant domains in which rehabilitation needs emerged in up to 1 year follow up were the neuromotor area in order to gain independence at home and outside the home, pain control, particularly after surgery, nursing, psychological support of patients and caregivers, and occupational activities (personal, work, school, social). CLINICAL REHABILITATION IMPACT: The findings of the present study suggest that: short and midterm clinical rehabilitation programs should be made available for patients operated on musculoskeletal tumors. Physical function recovery is only one aspect of rehabilitation, and psychosocial functioning must be taken into account and coordinated by a comprehensive team of specialists. Appropriate assessment tools should be used, and a continuum of care from the hospital to the patient's home should be promoted.

Influence of Immediate and Delayed Lower-Limb Amputation Compared with Lower-Limb Salvage on Functional and Mental Health Outcomes Post-Rehabilitation in the U.K. Military.

BACKGROUND: Medical practitioners face difficult decisions over whether to amputate or to salvage a lower limb that has undergone trauma. To our knowledge, there has been little evidence reporting the impact of different surgical decisions on functional and mental health outcomes following intensive rehabilitation that might inform decision-making. METHODS: This study is a retrospective, independent-group comparison of rehabilitation outcomes from a U.K. military complex trauma rehabilitation center. There were 100 procedures examined: 36 unilateral amputations (11 immediate-below-the-knee amputations, 15 delayed below-the-knee amputations, and 10 immediate above-the-knee amputations), 43 bilateral amputations, and 21 single-limb salvages (including 13 below-the-knee limb salvages); the patients had a mean age (and standard deviation) of 29 ± 6 years and a mean New Injury Severity Score of 34 ± 15 points. The outcome measures at completion of rehabilitation included a 6-minute walk test (6MWT), Defence Medical Rehabilitation Centre mobility and activities of daily living scores, screening for depression (Patient Health Questionnaire [PHQ-9]) and general anxiety disorder (General Anxiety Disorder 7-item scale [GAD-7]), mental health support, and pain scores. RESULTS: On completion of their rehabilitation, the unilateral amputation group walked significantly farther in 6 minutes (564 ± 92 m) than the limb-salvage group (483 ± 108 m; p < 0.05) and the bilateral amputation group (409 ± 106 m; p < 0.001). The delayed below-the-knee amputation group (595 ± 89 m) walked significantly farther than the group with limb salvage below the knee (472 ± 110 m; p < 0.05), and there was no significant difference between the group with delayed below-the-knee amputation and the group with immediate below-the-knee amputation (598 ± 63 m; p > 0.05). The limb-salvage group was less capable of running independently compared with all amputee groups. No significant differences (p > 0.05) were reported in mean mental health outcomes between the below-the-knee injury groups, and depression and anxiety scores were comparable with population norms. At discharge, 97% of all patients were able to control their pain. CONCLUSIONS: After completing a U.K. military interdisciplinary rehabilitation program, the unilateral amputation group demonstrated a significant functional advantage over the limb-salvage and bilateral amputation groups. We found that patients electing for delayed amputation below the knee after attempted limb salvage achieved superior functional gains in mobility compared with patients who underwent limb salvage below the knee and experienced no functional disadvantage compared with patients who underwent immediate amputation. The mental health outcomes were comparable with general population norms, optimizing the prospect of full integration back into society. LEVEL OF EVIDENCE: Therapeutic Level III.

Functional and psychological outcomes of delayed lower limb amputation following failed lower limb reconstruction.

PURPOSE: The purpose of this study was to evaluate the functional and psychological outcomes of patients who underwent delayed lower limb amputation following failed limb salvage surgery. METHODS: This retrospective, descriptive study evaluated functional outcomes using the Sickness Impact Profile (SIP) and Short Form-36 (SF-36) in 12 patients. Inclusion criteria included patients who underwent limb reconstruction and delayed amputation between July 2006 and December 2014, with an age range between 18 and 80 years of age, the ability to ambulate independently, a time interval between the last salvage procedure and amputation greater than six months, and a minimum follow-up of 24 months. Patients were contacted via telephone by the principal investigator and both the Sickness Impact Profile (SIP) and Short Form-36 (SF-36) were completed. Descriptive analysis (means and standard deviation) was used to determine outcomes for both SIP and SF-36 health profiles. RESULTS: Ten patients who had amputations following failed reconstruction (2006-2014) with a mean age of 53±10years were interviewed. Six patients had a SIP <5, three patients scored between five and 10 points and one scored >10 points. The main deficit on the SF-36 was in the physical component. The SF-36 scores demonstrated a mean score of 40.8±11.5 for the physical component, and 57.4±7.9 for the mental component. Three patients returned to work after amputation and continued performing their pre-injury duties as farmers. Three other patients returned to work, but were allocated to administrative duties. Two patients were pensioners at the time of their injuries, and the only female patient was a housewife. One patient went into early retirement. CONCLUSION: The results of this study strongly suggest that delayed amputation following failed limb salvage surgery can still result in good and satisfactory outcomes in the majority of patients and achieves results similar to early amputation and limb reconstruction techniques.

A telephone questionnaire in order to assess functional outcome after post-traumatic limb salvage surgery: Development and preliminary validation.

BACKGROUND: Post-traumatic limb salvage surgery is challenging and evaluation of the results remains arduous. No questionnaire specifically assessing functional outcome after post-traumatic limb salvage surgery of the lower extremity exists. Due to regionalization of specialized care, the patients' travel time to the hospital increases. To overcome a higher patients' travel burden, patients' follow up by telephone is an option. We aimed to develop a telephone questionnaire in order to assess functional outcome after post-traumatic limb salvage surgery of the lower extremity. METHODS: From a review of scores of functional assessment of the lower limb surgery, we have developed a telephone questionnaire. A prospective study was performed to validate this telephone questionnaire. Twenty patients were included. The participants were called to complete the telephone questionnaire twice with an interval of a week. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was completed during the second telephone call. The internal consistency was analyzed by the Cronbach's alpha (α). With the outcome scores of both completions, the test-retest reliability was analyzed by the interclass correlation coefficient (ICC) 2,k with a 95% confidence interval (95% CI). The outcome scores of the second telephone questionnaire and the WOMAC questionnaire were used for the construct validity analysis by the Spearman's rank correlation coefficient (r(s)) with a 95% CI. RESULTS: The internal consistency analysis revealed a α=0.62 which improved to α=0.92 after removing one question from the telephone questionnaire. The final version of the telephone questionnaire comprises 32 questions, divided in 3 subscales: function, daily life and psychology. The total score varies between 0 and 86 points. The test-retest reliability was ICC 2,k=0.93 (95% CI: 0.82-0.97) and the construct validity was r(s)=0.92 (95% CI: 0.81-0.97). CONCLUSIONS: We present a specific telephone questionnaire in order to assess functional outcomes after posttraumatic limb salvage surgery of the lower extremity. Further research on a large number of patients will be necessary to validate this newly developed questionnaire.

How does ankle-foot orthosis stiffness affect gait in patients with lower limb salvage?

BACKGROUND: Ankle-foot orthoses (AFOs) are commonly prescribed during rehabilitation after limb salvage. AFO stiffness is selected to help mitigate gait deficiencies. A new custom dynamic AFO, the Intrepid Dynamic Exoskeletal Orthosis (IDEO), is available to injured service members but prescription guidelines are limited. QUESTIONS/PURPOSES: In this study we ask (1) does dynamic AFO stiffness affect gait parameters such as joint angles, moments, and powers; and (2) can a given dynamic AFO stiffness normalize gait mechanics to noninjured control subjects? METHODS: Thirteen patients with lower limb salvage (ankle arthrodesis, neuropathy, foot/ankle reconstruction, etc) after major lower extremity trauma and 13 control subjects who had no lower extremity trauma and wore no orthosis underwent gait analysis at a standardized speed. Patients wore their custom IDEO with posterior struts of three different stiffnesses: nominal (clinically prescribed stiffness), compliant (20% less stiff), and stiff (20% stiffer). Joint angles, moments, powers, and ground reaction forces were compared across the varying stiffnesses of the orthoses tested and between the patient and control groups. RESULTS: An increase in AFO compliance resulted in 20% to 26% less knee flexion relative to the nominal (p = 0.003) and stiff (p = 0.001) conditions, respectively. Ankle range of motion and power generation were, on average, 56% (p < 0.001) and 63% (p < 0.001), respectively, less than controls as a result of the relatively fixed ankle position. CONCLUSIONS: Patients with limb salvage readily adapted to different dynamic AFO stiffnesses and demonstrated few biomechanical differences among conditions during walking. None of the stiffness conditions normalized gait to controls. CLINICAL RELEVANCE: The general lack of differences across a 40% range of strut stiffness suggests that orthotists do not need to invest large amounts of time identifying optimal device stiffness for patients who use dynamic AFOs for low-impact activities such as walking. However, choosing a stiffer strut may more readily translate to higher-impact activities and offer less chance of mechanical failure.

Return to duty after integrated orthotic and rehabilitation initiative.

OBJECTIVES: To determine the return to active duty rate of military service members undergoing lower extremity limb salvage while using a novel custom orthosis and specialized rehabilitation compared with those receiving a novel custom orthosis alone. DESIGN: Retrospective cohort study. SETTING: Military level I trauma center and tertiary referral center for limb salvage. PATIENTS/PARTICIPANTS: All active duty service members enrolled in our institution's Return to Run Clinical Pathway were analyzed retrospectively. Service members were enrolled if they sustained injuries with residual disability below the knee. Injuries typically involved substantial motor and/or nerve deficit, and the overwhelming majority was secondary to high-energy injuries. INTERVENTION: Service members were fitted with a customized orthosis, an Intrepid Dynamic Exoskeletal Orthosis (IDEO), for use during rehabilitation. Service members were divided into 2 groups: those who had participated in the Return to Run Clinical Pathway with an IDEO (group 1) and those who only were fitted with an IDEO only (group 2). MAIN OUTCOME MEASURE: Return to military active duty rate. RESULTS: One hundred forty-six service members met the inclusion criteria. Group 1 consisted of 115 service members and group 2 consisted of 31 service members. Of those in group 1, 59 (51.3%) returned to active duty compared with 4 (12.9%) in group 2 (P = 0.0001). Mechanisms of injury were significant factors for return to duty (RTD), and those sustaining explosive mechanisms of injury or gunshot wounds had significantly lower RTD rates across both groups. CONCLUSIONS: Active duty service members participating in an integrated orthotic and rehabilitation initiative after a lower extremity injury have a higher rate of RTD than previous reports, and it is significantly higher than the orthotic device alone.

Standardization of rehabilitation after limb salvage surgery for sarcomas improves patients' outcome.

BACKGROUND AND OBJECTIVE: The purpose of this study is to establish a standardized postoperative rehabilitation protocol following limb salvage surgery (LSS) in patients with primary bone sarcoma in five major anatomical locations: distal femur, proximal tibia, proximal and total femur, humerus and shoulder girdle and pelvic resections. SETTING AND DESIGN: Retrospective study. PATIENTS AND METHODS: All LSSs were performed by an orthopedic oncology surgeon, and rehabilitation of all patients was based on a devised standardized rehabilitation protocol. Patient outcomes were measured using the modified Musculoskeletal Tumor Society-International Symposium on the Limb Salvage (MSTS-ISOLS) scoring system. RESULTS: A total of 59 patients received LSS in the above mentioned locations; endoprostheses were used in 49, bone allograft in five, while no replacements were made in five patients. At a mean follow-up of 24 months, the mean modified MSTS-ISOLS score for all patients was 87% (95% CI; 0.85-0.89). The highest scores were encountered for patients with distal femur replacement: 93% (95% CI; 0.91-0.95). Seven patients had interruption of more than six weeks in their rehabilitation and had a mean score of 71% (95% CI; 0.64-0.82). CONCLUSION: The proposed rehabilitation protocol is a comprehensive, organized and applicable guideline to be used after performing LSS at the above mentioned anatomical locations. The use of standardized rehabilitation protocol resulted in improved patient functional outcome.

Eighteen-year follow-up after rotationplasty for a grade IIIC open fracture of the distal femur.

We report the 18-year follow-up of a patient who underwent rotationplasty for severe bone loss and infection after an grade IIIC open fracture of the distal femur. The patient is now 49 years old and fully satisfied with his life. During the follow-up period, he has never had significant physical or psychological problems directly concerning the rotationplasty. The analysis of quality of life using the SF36 questionnaire revealed even higher scores than the normal healthy population in seven out of eight sub-categories. Clinical examination revealed bland soft tissues without hyperkeratosis or other signs of maladaptation. Articular and cutaneous proprioception was intact all over the left leg. The active extension/flexion of the prosthetic knee was 0°-0°-100° and 10°-0°-70° of the ankle joint. Manual testing of motor strength revealed grade five of five for dorsiflexion and plantar flexion of the ankle. Gait patterns including climbing slopes and stairs were close to normal. Examination in sports physiology showed lower maximum power of hip and knee muscles compared to the healthy side, but better muscular endurance. These findings emphasize that rotationplasty can be a good alternative to arthrodesis or amputation in trauma patients providing high satisfaction and activity levels in the long-term follow-up.

Deployment after limb salvage for high-energy lower-extremity trauma.

BACKGROUND: Many wounded warriors experienced high-energy lower-extremity trauma (HELET) that may be limb threatening. Volumetric muscle loss, posttraumatic osteoarthritis, nerve injuries, and pain may severely limit physical function. Several wounded warriors express a strong desire to return to their units and be deployed in their original military occupational specialty. We began the return-to-run (RTR) clinical pathway at our institution 2 years ago to facilitate high-performance goals such as these. It involves an energy storing ankle foot orthosis, the intrepid dynamic exoskeletal orthosis in combination with high-intensity, progression-oriented rehabilitation. We sought to determine the rate of deployment or predeployment training after participation in this noninvasive intervention. METHODS: A retrospective analysis of the RTR database was performed to determine the rate of deployment or predeployment training among those service members who began participation in the RTR between November of 2009 and March of 2011. Medical records were reviewed for demographics, injury, surgical data, and major complications. Requests for delayed amputation were recorded, and charts were reviewed to determine if patients eventually elected to proceed with amputation or if they chose to continue with limb salvage. RESULTS: Between November 2009 and March 2011, 87 service members completed the RTR. Of these, 17 (19.5%) have been deployed to combat or are in predeployment training. Sixteen serve in combat arms (nine Special Forces, four infantry/ranger, two combat engineers, and one gunner), and one is a member of the military intelligence community. Fifteen patients sustained their injuries as a result of HELET (four gunshot, five motor vehicle collisions, four explosions, one parachute injury, and one fall from height), one had idiopathic avascular necrosis of the talus, and one had an iatrogenic nerve injury after pelvic surgery. Six of the patients underwent circular external fixation, five received joint fusions (three ankle, two subtalar joint), and nine had major nerve injuries. Four initially desired amputation of their injured limb but have subsequently countermanded their request. CONCLUSION: Returning to high-level physical function after HELET is challenging. After implementation of the RTR clinical pathway with the intrepid dynamic exoskeletal orthosis, 19.5% of wounded warriors treated with the RTR have been deployed or will be deployed in the coming year.

Physical activity assessment in adolescents with limb salvage.

OBJECTIVES: To evaluate ambulatory activity differences between youth with limb salvage procedures and typically developing youth (TDY) and assess differences in self-reported activity levels in the 2 groups, to provide a basis for physical activity assessment in patients who had undergone limb salvage surgery and treatment planning that incorporates regaining normal physical and daily living activities. STUDY DESIGN: In this cohort comparison study, we compared ambulatory and self-reported activity levels in 20 youth (aged 11.7-20.8 years) who had undergone limb salvage surgery and a sex- and age-matched comparison cohort of 20 TDY. StepWatch activity monitor and Activity Scale for Kids data were used to answer these questions. RESULTS: Significant differences were found between the youth who had undergone limb salvage surgery and the TDY in total time active each day (43% vs 48%; P = .03), median total strides per day (4487 vs 7671; P = .001), and amount of time per day at high activity levels (20 minutes vs 47 minutes; P = .001). Self-reported overall physical activity, locomotion, and standing Activity Scale for Kids subscale scores were significantly lower in the youth undergoing limb salvage surgery compared with the TDY (summary score, 88.3 vs 97.7; P = .001). CONCLUSION: Patients undergoing limb salvage surgery exhibit reduced physical activity compared with normal age-matched controls.
