Study Design: The effect of Total Hip Replacement surgery (THR) upon spinal sagittal alignment and low back pain was assessed in patients with severe hip osteoarthritis.

Summary of Background Data: Osteoarthritis in the hip joint is associated with abnormal posture and gait due to hip flexion contracture and hip pain. This in turn may cause abnormal spinal sagittal alignment and secondarily induce low back and leg pain. However, there have been no reports regarding the corrective effect of Total Hip Replacement surgery upon spinal sagittal alignment in patients with osteoarthritis of the hip.

Methods: This study prospectively analyzed the results of 25 patients (15 females and 10 males, average age 67.4 years (32–84)) undergoing THR for severe osteoarthritis of the hip. Pre and post-surgical assessment included; sagittal measurement of Sacral Inclination (SI) and total Lumbar Lordosis (L1-S1) on standing lateral radiographs. Functional clinical outcomes for hip as well as low back were also evaluated using the Oswestry back Questionnaire, the Modified Harris Hip Score and Visual Analog Scale for lower back pain and hip pain accordingly.

All the radiographic and clinical evaluations were completed both before THR surgery and 3 months following the surgery during routine follow up.

Results: Mean Lumbar Lordosis before the surgery and in the follow up was 50.36 and 50.32 respectively. Mean sacral inclination before and after surgery were 39.06 and 38.16 respectively. Mean Functional outcomes as assessed by the HHS score before and after the surgery were 45.74 and 81.8 respectively. Mean Oswestry Questionnaire scores before and after the surgery were 36.72 and 24.08 respectively. Mean VAS scores for hip pain before and after the surgery were 7.08 and 2.52 respectively. Mean VAS scores for lower back pain before and after the surgery were 5.04 and 3.68 respectively.

Discussion: No Significant difference was found between the sagittal alignment of the spine before THR and 3 months following it. Interestingly, total hip replacement surgery significantly improved spinal functional outcome as well as relieved low back and hip pain.

Introduction: Long bone fracture treatment with interlocking intramedullary nails is associated with long operative procedures, re-operations and long periods of infirmity. We assessed the clinical and economical factors associated with tibial fracture fixation with interlocking nails in comparison to fixation with an expandable stainless steel intramedullary nail.

Methods: Eighty diaphysial tibial fractures were consecutively treated with either an interlocking intramedullary nail (n=53 patients) or an expandable nail (n=27 patients).

Results: The duration of surgery was 139 minutes with interlocking nails and 52.9 minutes with expandable nails (p< 0.001). Re-hospitalization and re-operations were required in 51% and 42% of patients with interlocking nails respectively, compared to one patient (3%) with an expandable nail (p< 0.0001). Complications related to the introduction of interlocking screws (e.g., neurological deficits, screw breakage and delayed or non-union requiring dynamization) occurred in 19 interlocking nail patients and in none of the expandable nail patients. Union was achieved after 17.5 weeks (mean) with the interlocking nails compared to 11.5 weeks for expandable nails (p=0.071). The beneficial economic ramifications of using expandable nails were a 39% reduction in hospital expenses.

Conclusions: The use of an expandable stainless steel intramedullary nail is associated with a substantial reduction in clinical complications and hospital costs. An expandable nail features a unique fixation modality, which has superior mechanical fixation strength and is better adapted to the physiological bone healing process.

Based on these advantages, as well as its simplicity in use and short surgical technique, we recommend it for treatment of long bone fractures.

Introduction: Meralgia paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve, mainly associated with either injury or pressure to the nerve. Although this entity is well described, most clinical series have employed numerous treatment methods; therefore, the efficacy of individual modalities is unclear.

We describe our experience of 79 patients with complaints consistent with MP, treated, by the senior author, over a 13-year period.

Materials and Methods: Patients were managed in accordant to a structured protocol:

Initial management consisted of anti inflammatory agents, rest and redaction of aggravating factors.

Diagnostic nerve block test was carried out for those who were refractory to the above treatment. All patients who responded to the local anesthetic test were treated with local infiltration of corticosteroids.

Surgical intervention was reserved for patients who responded to the lidociane test but were refractory to repeated corticosteroids injections. Patients who failed to respond to the test injection were evaluated by CT-scan of the lumbar spine and by abdominal ultrasound (for female patients only). Follow-up ranged 1–13 years.

Results: Twenty-one patients (27%) reported satisfactory results flowing initial management. Local anesthetic yielded rapid relief of symptoms in 50 patients (86%), two additional patients responded to a second nerve block test (where a wider area was infiltrated).

In forty-two out of 52 patients (81%) who responded to the nerve block test and received treatment with corticosteroid injections, Long-lasting relief was obtained.

Three patients refractory to repeated injections of corticosteroid underwent surgery (neurolysis in one patient and nerve resection in two).

CT-scan of the lumbar spine revealed significant spinal stenosis and nerve root compression at the level of L1–3 in 3 out of 6 patients.

Conclusion: Idiopathic MP usually improves with nonoperative modalities. Temporary relief of symptoms following LFCN block is a specific diagnostic test, and is a good predictor of success following local corticosteroid injection. Surgery is seldom necessary and should be considered only if intractable pain persists despite such measures.
