effect of durations of wheelchair tilt in space and recline on skin perfusion over the Ischial Tuberosity in people with spinal cord injury
Archives of Physical Medicine and Rehabilitation, 2013Co-Authors: Fuyuan Liao, Maria Jones, Laura A Rice, Teresa TisdellAbstract:Abstract Objective To compare the efficacy of various durations of wheelchair tilt-in-space and recline on enhancing skin perfusion over the Ischial Tuberosity in people with spinal cord injury (SCI). Design Repeated-measures, intervention and outcomes measure design. Setting University research laboratory. Participants Power wheelchair users with SCI (N=9). Interventions Three protocols of various durations (3min, 1min, and 0min) of wheelchair tilt-in-space and recline were randomly assigned to the participants. Each protocol consisted of a baseline 15-minute sitting, a duration of 0- to 3-minute reclined and tilted, a second 15-minute sitting, and a 5-minute recovery. The position at the baseline and the second sitting was no tilt/recline of the participant and at the reclined and tilted and recovery was at 35° tilt-in-space and 120° recline. Main Outcome Measures Skin perfusion response to tilt and recline was assessed by laser Doppler and was normalized to mean skin perfusion at the baseline sitting. Results The results showed that mean skin perfusion during recovery at the 3-minute duration was significantly higher than that at the 1-minute duration ( P P Conclusions Our findings suggest that performing the 3-minute duration of wheelchair tilt-in-space and recline is more effective than the 1-minute duration in enhancing skin perfusion of weight-bearing soft tissues.

effect of wheelchair tilt in space and recline angles on skin perfusion over the Ischial Tuberosity in people with spinal cord injury
Archives of Physical Medicine and Rehabilitation, 2010Co-Authors: Maria Jones, Meheroz H Rabadi, Robert D Foreman, Amy ThiessenAbstract:Abstract Jan Y-K, Jones MA, Rabadi MH, Foreman RD, Thiessen A. Effect of wheelchair tilt-in-space and recline angles on skin perfusion over the Ischial Tuberosity in people with spinal cord injury. Objective To investigate the efficacy of wheelchair tilt-in-space and recline on enhancing skin perfusion over the Ischial Tuberosity in wheelchair users with spinal cord injury (SCI). Design Repeated-measures, intervention, and outcomes-measure design. Setting A university research laboratory. Participants Wheelchair users with SCI (N=11; 9 men, 2 women; mean ± SD age, 37.7±14.2y; body mass index, 24.7±2.6kg/m 2 ; duration of injury, 8.1±7.5y). Interventions Protocols (N=6) of various wheelchair tilt-in-space and recline angles were randomly assigned to participants. Each protocol consisted of a 5-minute sitting-induced ischemic period and a 5-minute wheelchair tilt-in-space and recline pressure-relieving period. Participants sat in a position without tilt or recline for 5 minutes and then sat in 1 of 6 wheelchair tilted and reclined positions, including (1) 15° tilt-in-space and 100° recline, (2) 25° tilt-in-space and 100° recline, (3) 35° tilt-in-space and 100° recline, (4) 15° tilt-in-space and 120° recline, (5) 25° tilt-in-space and 120° recline, and (6) 35° tilt-in-space and 120° recline. A 5-minute washout period (at 35° tilt-in-space and 120° recline) was allowed between protocols. Main Outcome Measures Laser Doppler flowmetry was used to measure skin perfusion over the Ischial Tuberosity in response to changes in body positions caused by performing wheelchair tilt-in-space and recline. Skin perfusion response to wheelchair tilt-in-space and recline was normalized to skin perfusion of the upright seated position (no tilt/recline). Results Combined with 100° recline, wheelchair tilt-in-space at 35° resulted in a significant increase in skin perfusion compared with the upright seated position (no tilt/recline; P P Conclusions Our results indicate that wheelchair tilt-in-space should be at least 35° for enhancing skin perfusion over the Ischial Tuberosity when combined with recline at 100° and should be at least 25° when combined with recline at 120°. Although smaller angles of wheelchair tilt-in-space and recline are preferred by wheelchair users for functional purposes, wheelchair tilt-in-space less than 25° and recline less than 100° may not be sufficient for effective pressure reduction for enhancing skin perfusion over the Ischial Tuberosity in people with SCI.

Ischiofemoral impingement and hamstring dysfunction as a potential pain generator after Ischial Tuberosity apophyseal fracture non-union/malunion
Knee Surgery Sports Traumatology Arthroscopy, 2017Co-Authors: Luke Spencer-gardner, Asheesh Bedi, Michael J. Stuart, Christopher M. Larson, Bryan T. Kelly, Aaron J. KrychAbstract:Purpose The purpose of this study was to describe the occurrence of ischiofemoral impingement (IFI) and hamstring dysfunction following malunion or non-union of Ischial Tuberosity apophyseal avulsion fractures and report the short-term outcomes of surgical treatment with regard to alleviating symptomatic extra-articular impingement. Methods All patients who underwent surgery for recalcitrant hip and buttock pain in the setting of prior Ischial Tuberosity avulsion fracture at three tertiary-level hip preservation centres were included for this review. A total of ten patients met our inclusion criteria and underwent sciatic neurolysis, resection of the Ischial Tuberosity fragment and hamstring reattachment. Clinical outcomes scores were collected post-operatively including the Modified Harris Hip Score (mHHS) and the Hip Outcomes Score (HOS). Results Ten patients with a mean age of 18 years (range 14–28) underwent surgery for symptomatic ischiofemoral impingement after Ischial Tuberosity avulsion fracture. At a mean of 2.2-year follow-up (range 1.7–3.5), the median post-operative mHHS was 89.7 (65.7–96.8) and HOS ADL and Sport subscales were 90 % or greater in all cases. Five patients (50 %) rated their hip as normal, and five patients (50 %) rated their hip as near normal. Conclusion Malunion or non-union following Ischial Tuberosity apophyseal fracture can lead to IFI and hamstring dysfunction. Clinically, the resultant pain and dysfunction is often chronic, and can be debilitating. In select cases, a reliable surgical technique is presented to improve hamstring function and correct ischiofemoral impingement in this setting with good-to-excellent outcomes in the majority of cases at short-term follow-up.

Atypical Coxa Saltans Due to Partial Proximal Hamstring Avulsion: A Case Presentation Highlighting the Role for Dynamic Sonography
Pm&r, 2015Co-Authors: Luke Spencer-gardner, Adam M. Pourcho, Jay Smith, Aaron J. KrychAbstract:Abstract Painful hip snapping can present as a rare sequela of proximal hamstring injury. We present a case of painful snapping of the conjoint tendon of the semitendinosus and biceps femoris over the Ischial Tuberosity in the setting of a partial proximal hamstring disruption. Dynamic ultrasonography identified the source of snapping and a persistent attachment of the conjoint tendon to the sacrotuberous ligament, which prevented retraction and allowed subluxation of the tendons across the Ischial Tuberosity. Following surgical transection of the persistent sacrotuberous ligament attachment to the conjoint tendon and tendon reattachment, the patient's symptoms resolved with full return of function.

tardy sciatic nerve palsy following apophyseal avulsion fracture of the Ischial Tuberosity case report
Journal of Neurosurgery, 1998Co-Authors: Robert J Spinner, John L D Atkinson, Doris E Wenger, Michael J. StuartAbstract:This 4 1-year-old man presented with a 2-year history of symptoms and signs of sciatic nerve compression. Imaging studies revealed a large ossified fragment within the biceps muscle of the thigh abutting the sciatic nerve at the level of the lesser trochanter. The bony fragment resulted from an unrecognized apophyseal avulsion fracture of the Ischial Tuberosity, which the patient had sustained while sprinting 27 years earlier. External neurolysis of the sciatic nerve and excision of the mass led to a successful outcome.
