Osteoid osteoma mimicking overuse syndromes in athletes.

This article reports the clinical features, findings at imaging, management and outcome of five athletes who presented with osteoid osteoma. The diagnosis was missed initially in all the athletes, who were managed for an overuse syndrome for many months before receiving a correct diagnosis. Osteoid osteoma can cause atypical pain, and therefore lead to delay in diagnosis and inappropriate management. Each injured athlete must be fully evaluated by history, physical examination and appropriate imaging investigations to minimize the rate of misdiagnosis and underestimation, unnecessary procedures, and delayed management.

Prognostic factors in prosthetic rehabilitation of bilateral dysvascular above-knee amputee: is the stump condition an influencing factor?

AIM: The aim of this study was to evaluate the prognostic factors for rehabilitation outcome in bilateral dysvascular lower limb amputees, specifically to ascertain how the stump condition can influence the mobility outcome. METHODS: A retrospective study of 30 selected bilateral above-knee amputees for vascular disease was carried out. Barthel Index (BI) was given and stump condition was assessed at admission and at discharge. Influence of age, comorbidities and stump condition on effectiveness of BI was evaluated. Locomotor Capability Index (LCI) was performed at discharge. Influence of stump problems (pain, flexion, pain with flexion) on LCI was evaluated. RESULTS: At discharge, 25 patients were able to ambulate. Age and pathological conditions of stumps correlated negatively with BI effectiveness. LCI values were higher for patients with ideal stumps and lower for patients with combined stump pain and flexion deformities. Post hoc analysis showed that the principal factor negatively influencing the LCI score was the presence of stump flexion deformities. CONCLUSIONS: In our homogeneous group of bilateral amputees, age reduced the possibility of improving the level of autonomy. Good stump quality is one of the major determinants of mobility outcome. Efforts should be made to minimize stump complications. In particular, incorrect positioning of the stump, which is responsible for hip flexor retraction, should be avoided after surgery.

Residual limb wounds or ulcers heal in transtibial amputees using an active suction socket system. A randomized controlled study.

BACKGROUND: The factors that determine successful rehabilitation after lower limb amputation have been widely investigated in the literature, but little attention has been paid to the type of prosthesis and clinical state of the residual limb, particularly the presence of open ulcers. AIM: The aim of this study was to investigate the effects of a vacuum-assisted socket system (VASS) in a sample of trans-tibial amputees with wounds or ulcers on the stump and to evaluate prosthesis use as a primary outcome. Secondary outcome measures were mobility with the prosthesis, pain associated with prosthesis use, and wound/ulcer healing. STUDY DESIGN: Randomized controlled study. SETTING: Inpatient. POPULATION: Twenty dysvascular transtibial amputees suffering from ulcers due to prosthesis use or delayed wound healing post-amputation were enrolled. METHODS: Participants were separated into two groups: the experimental group was trained to use a VASS prosthesis in the presence of open ulcers/wounds on the stump; and the control group was trained to use a standard suction socket system prosthesis following ulcers/wounds healing. RESULTS: At the end of the 12-week rehabilitation program, all VASS users were able to walk independently with their prosthesis as reflected by a median Locomotor Capability Index (LCI) value of 42, whereas only five participants in the control group were able to walk independently with a median LCI value of 21. At the two-month follow-up, the participants used their VASS prostheses for 62 hours a week (median; range: 0-91), which was significantly longer than the control group using the standard prosthesis for 5 hours per week (range: 0-56, p=0.003). At the six-month follow-up, the difference between VASS-users (80, range: 0-112 hours a weeks) and control-users (59, range: 0-91) was no longer significant (p=0.191). Despite more intense use of the prosthesis, pain and wound healing did not significantly differ between the two groups. CONCLUSION: These results showed that the VASS prosthesis allowed early fitting with prompt ambulation recovery without inhibiting wound healing or increasing pain.
