Endoscopic calcaneoplasty with gastrocnemius recession for Haglund's syndrome: Is it safe and effective? Results from a retrospective case series.

BACKGROUND: Endoscopic calcaneoplasty (ECP) and gastrocnemius recession (GR) are procedures that have been described to effectively treat Haglund's deformity and insertional Achilles tendinopathy respectively. The purpose of our manuscript is to evaluate the efficacy and safety of ECP and GR with immediate weightbearing for the treatment of Haglund's deformity with mild to moderate insertional Achilles tendinopathy. METHODS: We performed ECP coupled with GR on 14 patients with an average age of 52 years. All patients demonstrated < 50% tendinous degeneration on MRI. All were allowed weightbearing as tolerated in a CAM boot within the first post-operative week. AOFAS scores and plain film radiographic findings were collected pre-operatively and post-operatively. RESULTS: The radiographic exam of the Fowler-Philip angle significantly improved from an average 60.1-40.7° (p < 0.001). The AOFAS ankle/hindfoot score significantly improved from an average 54.7-91.4 (p < 0.001). The average return to work was 7.5 weeks. There were two cases of temporary sural nerve paresthesia, and two cases of delayed wound healing. CONCLUSIONS: This is the first mid-term study evaluating the outcomes of ECP with GR. The results of our study suggest that ECP with GR followed by immediate weightbearing is a safe and effective procedure for the treatment of Haglund's deformity and mild to moderate insertional Achilles tendinopathy.

Type IV Cell-Mediated Hypersensitivity Reaction Caused by Titanium Implant Following Double Calcaneal Osteotomy and First Metatarsal-Cuneiform Arthrodesis: A Case Report and Review of the Literature.

Because of their inert character and desired biocompatibility, titanium implants have been universally accepted as safer alternatives to the conventional stainless steel orthopedic implants; however, recent emergence of type IV hypersensitivity reactions to titanium have included eczema, contact dermatitis, a prolonged febrile state, sterile osteonecrosis, and impaired fracture and wound healing. This report presents a patient with postoperative incision dehiscence and devascularization of surfaces in contact with titanium hardware after undergoing a double calcaneal osteotomy and a first metatarsal-cuneiform arthrodesis using titanium alloy implants. Titanium hypersensitivity was confirmed in this case through standard allergy patch testing by a board-certified immunologist. Complete healing occurred after diagnosis of the titanium allergy and hardware explant. To our knowledge, this is one of a few known allergies to titanium implants after foot and ankle surgery.

Reconstruction After Osteomyelitis of the Midfoot From High-Pressure Washer Injury.

Reports of ballistic injures to the extremities typically include those involving gunshot wounds. However, high-pressure washer injuries frequently lead to equally damaging injuries. These injuries should not be overlooked, because they can result in high morbidity and complication rates. Similar to the open fracture protocol, these injuries require prompt debridement and irrigation with administration of antibiotics to avoid limb loss. The present case report identified a delay in the treatment protocol that left limited options for the patient. However, the patient agreed to undergo staged reconstruction consisting of serial debridement, implantation of a polymethylmethacrylate antibiotic spacer, and eventual interpositional iliac crest arthrodesis of the midfoot. At a follow-up point >5 years from the initial injury, the patient was walking with minimal pain and no limitations in his daily activities.

An Approach to Transmetatarsal Amputation to Encourage Immediate Weightbearing in Diabetic Patients.

Transmetatarsal amputation remains the standard treatment for the unsalvageable diabetic forefoot; however, this operation is often complicated by wound dehiscence, ulceration, and the need for additional surgery and tendon balancing. The technique described in the present report provides an uncomplicated suturing method for closure of a standard transmetatarsal amputation. A drill hole is created through the first, second, and fourth metatarsals, which facilitates added stability to the plantar flap of the residual metatarsals. The patients are encouraged to begin protected weightbearing as early as the first postoperative day. The security of the flap promotes immediate weightbearing, which could result in fewer postoperative complications of transmetatarsal amputations. Early weightbearing will not only encourage tendon rebalancing, but also could improve angiogenesis through capillary ingrowth.

Procalcitonin as a Biomarker for Predicting Amputation Level in Lower Extremity Infections.

Inflammatory markers are essential tools in the decision-making process for lower extremity infections. When coupled with objective findings, clinicians can more accurately diagnose and treat these entities. Typically, markers such as the white blood cell count, erythrocyte sedimentation rate, and C-reactive protein are used to initially assess these patients or monitor the progression of medical or surgical therapy. Procalcitonin is a newer inflammatory marker that is specific for an infectious process. Originally, procalcitonin was used to monitor antibiotic therapy and sepsis for patients in the intensive care setting, but it has now been expanded to other facets of medicine. The utility of procalcitonin has been described for diagnosing infection or osteomyelitis in diabetic foot ulcers. However, limited research has compared inflammatory marker levels and the level of amputation. A retrospective inpatient medical record review was performed of 156 consecutive patient occurrences during 25 months in which surgical intervention was required for a lower extremity infection and an initial procalcitonin level had been obtained. This initial procalcitonin value was then compared with the level of amputation at the final surgical intervention. A highly statistically significant difference was found when comparing those who underwent a below-the-knee or above-the-knee amputation (median procalcitonin 1.72 ng/mL) and those who did not (median procalcitonin 0.105 ng/mL; p < .001). Therefore, patients with higher initial procalcitonin values were more likely to undergo below-the-knee or above-the-knee amputation or require aggressive surgical intervention. Thus, the procalcitonin level can provide valuable initial information to the clinician.

Fact or fiction? Iatrogenic hallux abducto valgus secondary to tibial sesamoidectomy.

First ray function and hallux misalignment after isolated tibial sesamoidectomy have been topics of debate. Although sesamoidectomy has been proved to be effective in the relief of sesamoid pain, many foot and ankle surgeons remain hesitant to perform the procedure fearing a possible joint perturbation. To our knowledge, the present study is the first to evaluate both laboratory and clinical evidence of the association between isolated tibial sesamoidectomy and hallux abducto valgus deformity. The bench study consisted of 10 cadaveric limbs that were dissected and prepared for testing. Controlled valgus loads were applied before and after tibial sesamoidectomy. No significant difference was found in the joint position after sesamoidectomy in both the rectus (p = .36) and the dorsiflexed (p = .062) positions. The clinical evaluation consisted of a retrospective cohort of 5 females; all of whom underwent isolated tibial sesamoidectomy. The pre- and postoperative radiographs and self-reported pain scores (visual analog scale) were compared. None of the patients developed a postoperative hallux abducto valgus deformity. Neither the hallux abductus angle (p = .180) nor the intermetatarsal angle 1-2 (p = .180) changed significantly in the postoperative setting. The visual analog scale pain scores changed from a mean of 6.8 to 1, a significant difference (p = .042). Based on our observations and clinical experience, we believe that isolated tibial sesamoidectomy does not have a significant effect on the position of the first metatarsophalangeal joint when meticulous surgical technique is used to excise the sesamoid. Isolated tibial sesamoidectomy can provide substantial pain relief and appears to be a safe treatment for a variety of conditions affecting the tibial sesamoid.

A simple method of intramedullary fixation for proximal interphalangeal arthrodesis.

Lesser digital arthrodesis has become one of the most widely used techniques in foot and ankle surgery. When performing digital arthrodesis, surgeons have an abundance of options for implantable devices. We provide information on a simple method of achieving successful arthrodesis. An intramedullary Kirschner wire is implanted into the proximal phalanx with the intermediate phalanx compressed over the wire for rigid internal fixation to avoid the use of an external device. We have had results similar to those from the published data of more expensive implants.
