To assess healing pattern of Achilles tendons across the gap created by a percutaneous tenotomy and maintained by cast in club feet. Twenty-one tenotomies in 16 patients (Age range 12 weeks-36 months) were monitored with dynamic and static ultrasonographic studies. Ultrasounds were performed before and immediately after tenotomy and at approximately 3, 6 and 12 weeks post tenotomy. Cast removal was done at three weeks. Two patients above age of two were casted for 6 weeks. The healing pattern went through different phases although they were not distinctively exclusive from each other and did show considerable overlap. First phase showed formation of a bulbous mass with some continuity of scar tissue across tendon gap. The transition zone between new fibre and the original tend quite distinct. However dynamic ultrasound showed the Achilles tendon moved as a single unit. Second phase showed fibres resembling normal tendon crossing the gap and reduction of bulbous mass. The transition zone was still discernible. Final stage demonstrated more homogenous fibres of Achilles tendon with an indistinct transition zone. Two older children showed a distinctly longer process of healing. One child showed an irregular mass of fluid and soft tissue structures in the gap at six weeks. The other child demonstrated a relative reduction in the proportion of tendon fibres across the gap. At 12 weeks there was evidence of continuation of tendon fibres, but transition zone partly visible. Young Child (<1 Year): when cast immobilisation is discontinued, the tendon is in mid phase of healing. There may be a positive effect on continued improvement in dorsiflexion while using boots and bars. Older Child: safe to consider percutaneous tenotomy in children up to 3 years of ages provided the period of immobilisation is extended.Conclusion
The healing pattern went through different phases although they were not distinctively exclusive from each other and did show considerable overlap. First phase showed formation of bulbous mass with some continuity of scar tissue across tendon gap. The transition zone between new fibre and the original tend quite distinct.

The transition zone was still discernible. Final stage demonstrated more homogenous fibres of Achilles tendon with an indistinct transition zone. Two older children showed a distinctly longer process of healing.
At 3 weeks there was no evidence of healing. At 6 weeks an irregular mass of fluid and soft tissue structures was seen. At 12 weeks there was evidence of continuation of tendon fibres, but transition zone partly visible.
Older Child-Safe to consider percutaneous tenotomy in children up to 3 years of ages provided the period of immobilisation is extended.
Emergency ultrasound was only available in 9 patients. Only 5 (38%) of these 13 patients had septic arthritis. Septic arthritis group.
– Emergency ultrasound unavailable in 2 patents. They proceeded straight to arthrotomy yielding pus. – 3 had a preoperative ultrasound which confirmed the hip joint had an effusion. “Non Septic Arthritis of Hip” (8 patients).
– In 2 patients emergency ultrasound unavailable. They underwent emergency arthrotomy with negative findings of pus. – 1 actually had septic arthritis of knee. – 6 patients did have emergency ultrasound which showed no effusion. Emergency arthrotomy was cancelled. – They proceeded to MRI of Hip. MRI revealed pathology close to but not involving the hip: Pelvic osteomyelitis, Psoas abscess, Gluteal abscess secondary to small bowel fistula Cellulitis of medial thigh Femoral Epiphysis osteomyelitis and inflammation of tendon secondary to line insertion. Inflammation of rectus femoris tendon (secondary to central line insertion). Conclusion: Use of ultrasound avoided unnecessary arthrotomy in 6 patients (48%). If ultrasound was available in all cases, then 8 (63%) patients would have avoided an unnecessary arthrotomy. Out of hours urgent hip ultrasound may be difficult to request. However our recent experience leads us to propose that if available ultrasound should be performed in all suspected case of hip septic arthritis prior to surgical drainage. Pathology in the vicinity of the hip can often masquerade convincingly as a septic hip joint.

osteomylelitis has traditionally been managed by intravenous antibiotics for 4 to 6 weeks. This requires a prolonged in patient stay, inconvenience to parents, morbidity and unnecessary cost. A number of authors have suggested that shortened course of intravenous antibiotics 7–10 days are effective. In 2001 we started to prospectively evaluate a shortened 3 day of intravenous antibiotic regime. We prospectively treated 36 cases of acute osteomyelitis and 30 cases of acute septic arthritis in children. These were confirmed by positive blood culture, positive aspirate culture, raised WCC in joint aspirate for septic arthritis or positive bone scan/culture for osteomyelitis. These patients were treated with a shortened course (3 days) of intravenous antibiotics following surgical drainage when required. Serial measurements of inflammatory markers and clinical status were recorded. On Day 4 of admission if clinical and biochemical parameters improved patients commenced high dose oral antibiotics. If no improvement they continued IV abx and consideration for repeat washout given. Patients discharged with three week course of antibiotics. Endpoint analysis of duration of IV administration, inpatient stay, readmission/ reoccurrence was undertaken.
This studies reviews the outcomes of a short course regime started in 2001.
Patients were treated with a 3 day course of intravenous antibiotics, following surgical drainage of joints when required. Providing the clinical and biochemical parameters were improving patients then received 3 weeks oral antibiotics. The duration of IV administration and of inpatient stay and any incidence of readmission/reoccurrence was noted. Serial measurements of inflammatory markers were recorded.
